Data is the key target for security breaches…..… and Database Servers Are the Primary Source of Breached Data
http://www.verizonbusiness.com/resources/reports/rp_data-breach-investigations-report-2012_en_xg.pdf
2012 Data Breach Report from Verizon Business RISK Team
Database servers contain your clients’most valuable information
– Financial records– Customer information– Credit card and other account records– Personally identifiable information– Patient records
High volumes of structured dataEasy to access
“Go where the money is… and go there often.” - Willie Sutton

Verizon has a team that on a yearly basis analyzes risk and breaches in the digital world, looking for attack trends and pattern changes. Akin to the work we do with X-Force. For several years they have seen a trend, where the great majority of records breached came from databases, regardless of the source of the breach. So we reach a conclusion that databases are a major point of compromise. This may not be surprising, since here is where we find the most critical enterprise data worth stealing or violating. And since it is structured, it is easier to find. This is where Guardium has focused its attention up to now, but as more and more data gets stored in nosql databases or other nonrelationaldatabases, Guardium is tackling this problem as well and has an offering for Hadoop data activity monitoring.
Insider attacks are another particularly big issue when viewed from the perspective of production databases, because they are unique complex systems that are generally completely under the control of the DBAs that administer them. In fact survey of database administers routinely verify that issue; 62% of organization have no way to control what administrators do with their organizations most sensitive data; and the majority can’t even detect if inappropriate activity is taking place.

Native Database Logging
• Significant labor cost to review data and maintain process• High performance impact on DBMS from native logging• Not real time• Does not meet auditor requirements for Separation of Duties• Audit trail is not secure• Inconsistent policies enterprise-wide
At IBM we’ve been fortunate to consult with hundreds of enterprises world-wide that are seeking to secure their sensitive databases. Most fall into one of two categories. Either they have no database security solution in place, or they have attempted to build a “home grown” solution based on native auditing. Most of the larger enterprises fall in the latter category.
Let’s take a moment to explore how these home grown solutions are built, and why you may not want to go down that path. These systems are built on the native logging facilities of the databases; which are turned on to enabling auditing. Since they are distributed, scripts are typically written to scrape those logs, centralize the information and clean it up. Then reports are written to simplify examination of the information. On a periodic basis some poor individual examines these logs looking for inappropriate activity. When an anomaly is identified the individual responsible for that system is contacted, typically through email, and some manual system; a spreadsheet or database is used to track the incidents and responses.
This not a very good approach to securing your company’s most valuable assets for a variety of reasons:1. It is a costly approach, involving significant labor to develop the software and do the manual remediation
discussed. 2. Secondly, many companies can not implement, or sustain the approach due to the overhead incurred
when the native logging facilities are enabled. The overhead typically ranges from 10% to 45% of CPU cycles.
3. And it is obvious this type of system is not real time. By the time an anomaly is discovered, your valuable data is long since gone.
4. From a compliance perspective this type of approach is now being challenged by auditors, as it does not provide the separation of duties they require. Privileged users like DBAs are required to run the system; they can turn off the native auditing if they want to do something inappropriate, or modify the centralized logs
5. And of course the whole system is not secure; it can be compromised at many points6. And last of all, this type of approach does not provide consistent information enterprise wide, as the
underlying audit facilities deliver inconsistent information.

Historical perspective: What is Guardium?
Guardium, the company, was founded in 2002–Innovated a non-invasive solution for
continuous database auditingGuardium was acquired by IBM in 2009
The ‘Guardium’ name was extended to other products in the IBM Information Management portfolio that focus on data security and protection (that’s how good it is!)
InfoSphere Guardium Data Activity Monitoring InfoSphere Guardium Vulnerability AssessmentInfoSphere Guardium Data EncryptionInfoSphere Guardium Data Redaction
The ‘original’ Guardium and our focus for
today’s talk
The focus of this topic is the technology acquired by IBM from Guardium and is now marketed as two main offerings “InfoSphere Guardium Data Activity Monitoring and IG Vulnerability Assessment. InfoSphere Guardium Data Encryption encrypts databases and files “in place”and avoids the need to re-architect databases, files, or storage networks. Inserted above the file system and/or logical volume layers, InfoSphere Guardium Data Encryption is transparent to users, applications, databases and storage subsystems. It requires no coding, no modification to applications or databases. http://www.ibm.com/software/data/guardium/encryption-expert/InfoSphere Guardium Data Redaction protects sensitive data in documents, forms and files from unintentional disclosure by detecting & removing the data from the document version openly shared. It supports many document formats, including scanned documents, PDF, TIFF, XML and Microsoft® Word. Redaction usually happens as a result of a request, or a need to share select information. redaction is not a replacement for: Encryption,Proper access control , Secure document lifecycle management tools Web page: http://www.ibm.com/software/data/guardium/data-redaction/

And where does it fit?
InfoSphere Information Governance
Guardium has the privilege to be a key component in two IBM strategies: First the InfoSphere Information Governance Strategy, where there is a need to provide customers with trusted, relevant, and governed data throughout the information lifecycle. And with the Security Systems framework, where the protection of sensitive data is ultimately the essence of what enterprises want to accomplish.
Guardium integrates with and complements IM products, such as InfoSphere Discovery and Optim Archiving, as well as with Security products like QRadarand AppScan. For example, Guardium complements Optim Test Data Management solutions by monitoring sensitive data access in test environments/ It also can complement Optim Data Growth solutions with the ability to monitor access to both active and inactive (archived) data

Central Management & Aggregation Manage and use large deployments as a single federated systemCentral Management & Aggregation Manage and use large deployments as a single federated system
And so, at high level, Guardium offers two product suites1.Guardium Data Activity Monitoring (DAM) - to monitor dynamic data in real time, log the activity for compliance purposes and respond in real-time on any unauthorized or suspicious activity, either by triggering an alert on any unauthorized activity. Data discover and classification Crawls the network as directed by the user's configuration settings to find new database instances. Also finds and classifies sensitive data inside databases, using an intelligent database crawler to search for customizable patterns. Once sensitive objects have been located, they are automatically tagged with meta-data classifications such as “Regulated Record” and added to groups of items with similar properties, which ensures that appropriate policies are automatically applied to groups of objects with similar properties. Application end-user ID application (part of the DAM offering) identifies application users associated with specific database queries and transactions, in connection pooling environments where applications use a generic service account to access the database.The Advanced DAM package adds prevention functions such as blocking and masking – to actively prevent unauthorized activity and protect leakage of sensitive data. 2.Database Vulnerability Assessment (VA) - Scans database infrastructure for vulnerabilities such as missing patches, misconfigured privileges and default accounts. Also checks for behavioral or dynamic vulnerabilities by analyzing monitored activities, such as excessive number of failed logins or privileged users sharing credentials. The Advanced VA package also include the following functions:
1. Configuration Audit System (CAS): Tracks all changes to objects external to the database that have security implications – such as configuration files, environment variables, registry variables and executables such as shell scripts, Java and XML programs. To accelerate deployment, CAS includes a best practices library with hundreds of preconfigured knowledge templates for all major OS and DBMS combinations.
2. Entitlement Reports (ER): Provide a simple means of understanding user rights across the enterprise, including those granted through roles and groups, by aggregating and presenting in pre-defined reports entitlement information from across database instances.
Central Management and Aggregation Provides centralized management of multiple collectors via a single Web-based console. Includes centralized management of cross-DBMS security policies and hardware appliancesettings such as archiving schedules. Creates federated system from multiple Collectors.

VA helps identify common security configuration issues like:
-Patch levels on database servers -Administrators are sharing credentials-Users are still using default passwords
There are three important categories (Observed traffic, Database configuration, Operating System configuration) of tests to ensure complete analysis of your database infrastructure.Here are the testing methods used (from the Guardium Help Book)Guardium’s Database Vulnerability Assessment combines three essential testing methods to guarantee full depth and breadth of coverage.

Assessment tests give you information to help you correct failures and to show improvement over time. You can also create your own tests. A query based test is either a pre-defined or user-defined test that can be quickly and easy created by defining or modifying a SQL query, which will be run against database datasource and results compared to a predefined test value. See backup slides for an example. Once you've established a good VA score, you know your configuration is in good shape and you want to "lock down" the system by installing the Guardium Configuration Audit System (CAS) module, that will alert you on any change in configuration, file permissions, environment variables, etc." -- and it is part of the VA Advanced, which makes it a natural next-step for VA. CAS Tracks all changes that can affect the security of database environments outside the scope of the database engine• Tracks changes to database configuration files and other external objects that can affect your database security posture, such as ––Environment/registry variables, ––Configuration files (e.g. SQLNET.ORA, NAMES.ORA), ––Shell scripts, ––OS files, ––Executables such as Java programs• Required for all governance and risk management implementations• Implements security best practices with no administrator workCAS is a light-weight agent that runs on the server where database instances are installed. CAS monitors all changes to various constructs, including changes to files, file ownership and permission definitions, registry values, environment variables, and database structures. It will then poll these constructs based on a set of periods defined by the user and, if there are any changes, it will notify the InfoSphere Guardium server precisely which element was changed, what the new value is (versus the old value), etc. CAS works from a template that defines what to monitor. The InfoSphere Guardium system includes a set of predefined templates that define the best practices for monitoring in several different database environments

Heterogeneous support including System z and IBM i data servers
Example of detecting access to the database server from someone using the App Server credentials.Alerting is one of the options you have for policy rules. You can set up pretty fine-grained rules. Alerts can be sent to email, syslog and/or to a SIEM system such as QRAdar. They will also appear on the Incident Management tab of the Guardium UI. Be careful about how yo uset the Action – Alert per match could end up sending a lot of emails to someone depending on the type of SQL statement. Notes:The most common type of exception rule created is to alert on x number of failed login attempts within x minutes; for example 3 failed login attempts within 5 minutes.To create this alert, create a new exception rule as follows:•Action = Alert Per Match•Minimum Count = 3•Reset Interval = 5•Excpt. Type = LOGIN_FAILED•DB User = . <period>. Placing a period in DB User causes to the system to place a counter on DB User, so that you will only receive an alert the same user attempts to login three times with in five minutes. Otherwise, it will alert whenever there are three failed logins from any three users within five minutes, which could result in a great deal of false positives.

Preventing Unauthorized Access
Configurable behavior to block access for example of privileged users on sensitive data. Guardium solution works across multiple different database types and does not rely on an appliance between the App Server and database to do this. No impact to the legitimate Application Server traffic.SGATE – an extension of the S-TAP Agent resides at the kernel level on the Database Server. S-GATE can look for Privileged User access specifically and hold only this traffic for validation Guardium will hold the transaction – do an analysis – and allow it only if it doesn’t violate a policy. If the Privileged User violates a policy – Guardium can block this and report or alert on the violation.Other solutions that rely on using an inline apliance, would add latency to the application traffi and
would not be able to block a user at the database console – it can’t block local access.Using this reqiures you configure the guard_tap.ini file and create a policy ruleHere’s part of guard_tap.ini.firewall_default_state=0firewall_fail_close=0firewall_force_unwatch=NULLfirewall_force_watch=NULLfirewall_installed=1firewall_timeout=10

It’s critical to keep private data private, and that includes keeping it private from authorized users such as DBAs.Guardium can mask data using a single solution across multiple database types. Redaction (Scrub) rules should be set on the session level (meaning, trigger rules on session attributes like IPs, Users, etc), not on the SQL level / attributes (like -OBJECT_NAME or VERB), because if you set the scrub rule on the SQL that needs to be scrubbed it probably will take a few miliseconds for the scrub instructions to make it to the S-TAP where some results may go though unmasked. To guarantee all SQL is scrubbed, set the S-TAP (S-GATE) default mode to "attach"for all sessions (in guard_tap.ini). This will guarantee that no command goes through without being inspected by the rules engine and holding each request and waiting for the policy's verdict on the request. This deployment will introduce some latency but this is the way to ensure 100% scrubbed data. For more information, see the Guardium “Protect” Help Book.

File DataFile Data
File DataFile Data
InfoSphere Guardium Encryption Expert uses a proven and highly effective encryption process called MetaClear. MetaClear encryption protects the file data while leaving the File System MetaData (the data about the data) in the clear. There are three benefits of MetaClear encryption
* Transparency : because the outward appearance of the files do not change there is not impact to the OS, databases, storage, end-users, etc.
* Need to know : Applications and privilege administrators can still access protected data but may not be allowed to see the file data in clear-text. This meets separation of duties requirements. It also enforces need to know policies.
* Performance : we only encrypt/decrypt the specific portion of the file that is being processed. This has major implications in databases since a database doesn’t use all of it’s data at once, only a few rows at a time.

Included with VA Advanced
Entitlement reviews are the process of validating and ensuring that users only have the privileges required to perform their duties. Along with authenticating users and restricting role-based access privileges to data,even for the most privileged database users, there is a need to periodically perform entitlement reviews, the process of validating and ensuring that users only have the privileges required to perform their duties. This is also known as database user rights attestation reporting.Use Guardium’s predefined database entitlement (privilege) reports (for example) to see who has system privileges and who has granted these privileges to other users and roles. Database entitlement reports are important for auditors tracking changes to database access and to ensure that security holes do not exist from lingering accounts or ill-granted privileges.Custom database entitlement reports have been created to save configuration time and facilitate the uploading and reporting of data. Entitlement reports for DB2 for z/OS are also provided.

Audit Process Overview
Business Owner(PCI Role)
Information Security(InfoSec Role)
Guardium Admin(Admin Role)
Business Owner approves or rejects new connections to database
Information Security confirms Business Owner recommendation
Guardium Admin only makes changes for “authorized” connections
If there are no new connections, report will be empty and automatically approved…
(ie. Don’t waste anyone’s time)
One thing all auditors are going to want to see is a process that ensures all incidents are investigated and remediated. InfoSphere Guardium is unique in providing an integrated compliance workflow automationapplication that automates the process of ensuring all incidents are addressed; which reduces your operational costs while quickly providing the audit trail required for compliance.
The compliance workflow tool gives you the flexibility to define unique custom processes for their different organizations or efforts, for example a different escalation or review steps for different parts of the organization to ensure checks and balances. In this example, we are using this workflow process to ensure review and approval of new database connections. It needs to be routed from the businessd owner, through information security and then to the Guardium Admin who can actually move the new connections to the “approved connections” group.
The workflow process also provides enough granularity to handle individual line items in a report, like rerouting a subset of issues for escalation or outside review.
These capabilities enable the cost benefits of automation to be realized; even in large, complex organizations where you have a variety of different processes, and a variety of incidents with differing remediation profiles this custom workflow can fit seamlessly into your organizational processes.

The Guardium appliance is hardened, by which we mean that there is no root access allowed to the data stored there. The heavy duty lifting of parsing and logging data traffic is done there. The appliance is easily deployableOnce setup, the Collector can gather all the audit information in a normalized format (like an SIEM for DBs). The Vulnerability Assessment tool will scan these DBs and DB Servers for needed patches or configuration hardening, based on periodically updated vulnerability templates.
STAP Agents are very lightweight. They require nochanges to the Database or Applications. Collectors (appliance) handle the heavy lifting (parsing, logging, etc) to reduce the impact on the database server. They are OS-specific (aka Linux, Windows) The S-TAP is listening for network packets between the db client and the db server. The Guardium Admin configures each S-TAPto listen to the correct database ports and to interpret the specific type of database that Guardium needs to listen for. These configurations are called ‘inspection engines’. There is also an automatic discovery process to do the db discovery for you and configure the inspection engines with the correct ports. The S-TAPS Monitor ALL Access via network (TCP) or local connections (Bequeath, Shared memory, named pipes, etc). A Privileged User working on the server console won’t be detected by any solution that only monitors network traffic, so be careful of SPAN port solutions only.The GUI is a web-based and is out of the box customized for different roles such as PCI auditor. It’s also quite customizable with the ability add and delete portlets for specific functions. Those customizations can be rolled out to others.

Once STAP has been installed and the inspection engines configured, STAP will start forwarding all database traffic to the collector. This traffic is analyzed, parsed, and logged by the sniffer process on the collector, as follows:
Traffic sent by STAPDatabase Client -> Database Server•Client/server network connections•Sessions (logins/logouts)•SQL requests (commands)
Database Server-> Database Client•Failed login messages•SQL errors•Result sets
Traffic analyzed, parsed and logged by the snifferDatabase Client -> Database Server•Client/server network connections•Sessions (logins/logouts)•SQL requests (commands)
Database Server-> Database Client•Failed login messages•SQL errors•Result sets

How do you get access to this information?
Here’s a simple example to illustrate the flow of a select statement. Remember, we learned that from the client to the server, we will pass on not just the ‘command’ (the Select statement in the above example) but relevant about the client/server network connection (client IP, server IP etc) and the session information (login, logout). This process does not introduce latency for the database server – it is completely unintrusive.
The Analysis Engine (colloquially known as ‘sniffer’) will parse the information and store it in the internal Guardium repository on the hardened appliance. There is no direct access to this data- you have to go to go through UI or API to run reports or set u palerts etc to make use of that data. As you will see in the next slide, the data is externalized as domains, entities and attributes, not usually the direct table names.

Which sessions to monitor/ignore (based on OS User, DB User, etc.)What traffic (SQLs, Exceptions, Returned data) to audit , and in what granularity (based on
the command, the tables, the user, etc.)
Now that the audit data is in the repository of the hardened collector, how do you get at it.. ? There are many out of the box reports, but it’s good to have an understanding of how those reports are created so you can really take advantage of the stored audit data for your own needs.
The audit data is represented in the Guardium system as a collection of domains, with appropriate entities and attributes associated with that domain. (The Appendices Help book includes more details about this.) Each Guardium role typically has access to a subset of domains, depending on the function of that role within the company. Guardium admin role users typically have access to all reporting domains.
This slide shows use of the query builder for creating reports and how the entities and attributes appear on the builder.

Policy Primer - Accessing the Policy Builder
Notes:To access the Policy Builder:•As a user with the admin role go to Tools -> Policy Builder•As a user with the user role go to Protect-> Security Policies -> Policy builderNote:For a policy, or any changes to a policy, to take effect, it must be installed.
To install a policy:•Go to the Administration Console, Policy Installation•Highlight the policy that you would to install and choose Install from the drop down list
If the groups contained within the policy are updated regularly, the installation should be scheduled by clicking Modify Schedule to open the general-purpose scheduling utility. For example, if you are using ‘Populate from Query’ to update a group of privileged users nightly, the policy should be scheduled to be reinstalled after the group update.
More than one installed policy is permitted at the same time. All installed policies are available for action and are run sequentially. The only limitation is that policies defined as selective audit policies can not be mixed with polices not defined as selective audit policies. If trying to mix policies, an error message will result when installing these mixed policies. The order of appearance can be controlled during the policy installation, such as first, last or somewhere in between. But the order of appearance can not be edited at a later date.
Remember –The policy must be installed after any modifications (such as new or changed rules) for the changes to take effect. You would use install&override option on the installation.

Concept information – Rule TypesThere are three types of rules, which will determine which fields are available in the policy rule builder.Access rule – An access rule evaluates client accesses and enables the creation of real time alerts.Exception rule - An exception rule evaluates real-time exceptions returned by the server. For example, it might test for five file permission exceptions within one minute.Extrusion rule - An extrusion rule) evaluates real-time data returned by the server (in response to requests). For example, it might test the returned data for numeric patterns that could be social security or credit card numbers. For extrusion rules only, portions of database query output (for example, credit card numbers) may be masked for certain users..

Central Manager provides “Enterprise Views”
Appliance TypesCollectorUsed to collect database activity, analyze it in real time and log it in the internal repository for further analysis and/or reacting in real-time (alerting, blocking, etc.). Use this unit for the real-time capture and analysis of the database activity.Aggregator Used to collect and merge information from multiple appliances (collectors and other aggregators) to produce a holistic view of the entire environment and generate enterprise-level reports. The Aggregator does not collect data itself; it just aggregates data from multiple sources.Central Manager Use this Appliance to manage and control multiple Guardium appliances.With Central Manager (CM), manage the entire Guardium deployment (all the collectors and aggregators) from a single console (the CM console). This includes patch installation, software updates and the management and configuration of queries, reports, groups, users, policies, etc.Note:In many environments, the Central Manager is also the Aggregator. Central Manager and Aggregator can be installed on the same appliance.Hierarchical AggregationGuardium also supports hierarchical aggregation, where multiple aggregation appliances merge upwards to a higher-level, central aggregation appliance. This is useful for multi-level views. For example, you may need to deploy one aggregation appliance for North America aggregating multiple units, another aggregation appliance for Asia aggregating multiple units, and a central, global aggregation appliance merging the contents of the North America and Asia aggregation appliances into a single corporate view. To consolidate data, all aggregated Guardium servers export data to the aggregation appliance on a scheduled basis. The aggregation appliance imports that data into a single database on the aggregation appliance, so that reports run on the aggregation appliance are based on the data consolidated from all of the aggregated Guardium servers.
Aggregation Processv Accomplished by exporting data on a daily basis from the source appliances to the Aggregator (copying daily export files to the aggregator).v Aggregator then goes over the uploaded files, extracts each file and merges it into the internal repository on the aggregator.For example, if you are running Guardium in an enterprise deployment, you may have multiple Guardium servers monitoring different environments (differentgeographic locations or business units, for example). It may be useful to collect all data in a central location to facilitate an enterprise view of database usage. You can accomplish this by exporting data from a number of servers to another server that has been configured (during the initial installation procedures) as an aggregation appliance. In such a deployment, you typically run all reports, assessments, audit processes, and so forth, on the aggregation appliance to achieve a wider view, not always an enterprise view.

Here you can see the collectors that are connected in this central management system. From here, you can install policies, distribute patches, etc.
In a central management configuration, one Guardium unit is designated as theCentral Manager. That unit can be used to monitor and control other Guardium units, which are referred to as managed units. Unmanaged units are referred to asstandalone units.The concept of a "local machine" can refer to any machine in the Central Management system. There are some applications (Audit Processes, Queries,Portlets, etc.) which can be run on both the Managed Units and the Central Manager. In both cases, the definitions come from the Central Manager and thedata comes from the local machine (which could also be the Central Manager). Once a Central Management system is set up, you can use either the Central Manager or a Managed Unit to create or modify most definitions. Keep in mindthat most of the definitions reside on the Central Manager, regardless of which machine the actual editing is done from.

Failover, Load Balancing, and “Grid”

In many cases only a single Guardium appliance will be defined as the host for an S-TAP. Additional hosts can be defined to provide a fail over and load balancing capability.
Failover. S-TAP collects and sends data to a Guardium host in near real time. S-TAP buffers the data, so that it can continue to work if the Guardium host is momentarilyunavailable. If the primary host is unavailable for an extended period of time (time can be shorter if the buffer is filling up), S-TAP can fail over to a secondary Guardium host. It will continue to send data to the secondary host until either that appliance becomes unavailable, until the S-TAP is restarted or a connection to the primary server has been reestablished and remains up for a period of 5*connection_timeout_sec seconds.(configurable in guard_tap.ini file, default is 60 seconds). In this case STAP will fail over from secondary Guardium host back to Primary Guardium host.When a failover of S-TAP occurs, session information can also be sent over to the current active Guardium host.

Grid: Elasticity for supporting large deployments - Simplify configuration management for STAPs to a primary Virtual IP and a secondary, etc Virtual IP. Benefits: Better uptime, easier scalability, less configuration complexity and less chance of lost S-Tap data.
Tested with Cisco and F5. Seamlessly add audit capacity when adding/changing your database infrastructure such as during Enterprise deployments / upgradesAutomate the relationship between STAPs and the Collectors - Add or remove collectors with no effect on the deployment.Simply and consistently configure STAPs.Provide a high degree of failover and load balancing.From a capacity management perspective, add resources, monitor infrastructure, adjust capacity as needed (or when something fails ☺)
The main value is connection balancing. Guardium S-Tap is a long lived connection. When the initial connection setup happens, the F5 BIG-IP or other load balancer will direct the connection to the least loaded Guardium host. The load balancer will at connection setup time, choose the least loaded Guardium server based on connections.. The other benefits of this solution are that the BIG-IP or other supported load balancer will detect an outage, take that Guardium Appliance out of service and then send a TCP reset which will force a new connection. All of this happens without the intervention of an administrator.
A final benefit is that the configuration complexity is reduced. Instead of mapping the IP addresses of multiple Guardium hosts in the appropriate .INI file, only the Virtual IP address is included, load balancer does the rest.
Configure the S-TAP to work with Load Balancer environment:Sqlguard_ip = Virtual IP address/hostname of the Load balancer (depending on load balancer setup)Participate_load_balancing = 3 (to send pre-exsistingsession information on every failover to the appliance)All_can_control = 1 (in order to be able to edit STAP configurations through GUI)

Quiz question!
If you need to create corporate audit reports as well as manage a large number of Collectors, which configuration do you need? Pick BEST answer:
1. Central Manager directly managing Collectors
2. Aggregator connected to Collectors
3. A web application to roll up your reports
4. A Central Manager and one or more Aggregators
The correct answer is 4. Central managers cannot directly manage collectors. Note that answer 2 could work if you had a central manager on the same appliance on the aggregator but it doesn’t say that! But in either case you will likely need a Central Manager to help you manage policies and definitions across the enterprise and aggregators to roll up data/reports.

Ability to create user hierarchies to ensure automatic filtering of results based on user’s database
Access managers define users and their roles in the system.I call out Data level security here because that’s a way you can define a hierarchy of users in the system and map that hierarchy to data sources. This allowsyou for example, to create a single report that will be automatically filtered based on the report receiver’s role in the hierarchy and whether they are associated with thedata in the report. The same report on database access could be sent to the Oracle DBA and the DB2 DBA and the Oracle DBA would see only data related to Oracle.. And the DB2 DBA would only see data related to DB2. And the DBA manager could see both sets of data.

Command Line Interface (CLI) and APIs (GuardAPI)
Command line interface used for configuration, troubleshooting and management of Guardium System
The extensive set of GuardAPIs can be used by a user with either admin or CLI Role for automation of repetitive tasks or for ongoing maintenance
– Creating datasources, adding user/members to groups, connection profiling, entitlement report automation and more
– Many are invokable from reports in the UI!
GuardAPIs are documented in the Appendices help book or from the Cli–To see a list of all grdapi commands, enter:
CLI> grdapi–To see the parameters for a particular command:
CLI> grdapi list_entry_location --help=true
The Guardium command line interface (CLI) is an administrative tool that allows for configuration, troubleshooting, and management of the Guardium system.Access to the CLI is either through the admin CLI account cli or one of the five CLI accounts (guardcli1,...,guardcli5). The five CLI accounts exist to aid in the separation of administrative duties. Access to the GuardAPI, which is a set of CLI commands to aid in the automation of repetitive tasks, requires the creation of a user by access manager and giving those accounts either the admin or cli role. Proper login to the CLI for the purpose of using GuardAPI requires the login with one of the five CLI accounts (guardcli1,...,guardcli5) and an additional login with guiuserby issuing the 'set guiuser' command.For information about creating a user with CLI authority, see this ‘how to’ in the Information Center http://publib.boulder.ibm.com/infocenter/igsec/v1/topic/com.ibm.guardium.using.doc/topics/how-to-create-a-user-with-the-proper-entitlements-to-login-to-cli.htmlTo list all GuardAPI commands available, enter the grdapi command with no arguments or use the 'grdapi commands' command with no search argument.For example:CLI> grdapiTo display the parameters for a particular command, enter the command
followed by '--help=true'. For example:CLI> grdapi list_entry_location --help=true

APIs enable automation and ease maintenance
Invoke API to add
member to group
Example: Add a member to a group from a report
This example shows how you can use the API to add an ‘authorized’MapReduce job to a group so it won’t appear in this report anymore.
In this example, we wanted to add Hadoop MapReduce job names to a group after they have been vetted so they won’t appear in the ‘unauthorized list’ report anymore. There is configuration work to add APIs to reports if they are not already included with the system. We have a document on this process if you’re interested, contact me [email protected].

Discovering Sensitive Data in Databases
• Discover database instances on network
• Catalog Search: Search the database catalog for table or column name
– Example: Search for tables where column name is like “%card%”
• Search by Permission: Search for the types of access that have been granted to users or roles
• Search for Data: Match specific values or patterns in the data
– Example: Search for objects matching guardium://CREDIT_CARD (a built-in pattern defining various credit card patterns)
• Search for Unstructured Data: Match specific values or patterns in an unstructured data file (CSV, Text, HTTP, HTTPS, Samba)

Identifying Fraud at the Application Layer
Issue: Application server uses generic service account to access DB– Doesn’t identify who initiated transaction (connection
pooling)Solution: Guardium tracks access to application user associated with specific SQL commands
– Out-of-the-box support for all major enterprise applications (Oracle EBS, PeopleSoft, SAP, Siebel, Business Objects, Cognos…) and custom applications (WebSphere, WebLogic, ….)
– Deterministic vs. time-based “best guess”– No changes to applications

Identifying fraud or Application Mis-Use
You need a solution that shows WHO did WHAT!
Native Auditing solutions and logging tools, don’t show this depth
Track access back to the application user associated with a specific command
Deterministically – not by ‘best guess’!
Whatever middleware you are using!
And with NO changes to the application or the database!

Should my customer service rep view 99 records in an hour?Monitoring Data Leakage from High-Value Databases
Is this normal?
What exactly did Joe see?
Another Example
Traditional Solutions can’t identify suspicious behavior within legitimate traffic
Joe is viewing an abnormally high number of customer information!
We can even take a look at what he saw!
Notice that the audit information is masked,so that someone viewing these reports doesn’t also see the customer information that
we’re auditing Joe for…
Knowing what was breached and to what extent is what we’re looking for!
Native logs won’t give you this information!

Tracking privileged users who switch accounts
What InfoSphere Guardium shows you:
User activity
Privileged User
1. Joe logs in to Linux
2. He switches to the Oracle shell account
3. Logs into Oracle as system
4. Gives himself a big bonus!
Native database logging/auditing & SIEM tools can't capture OS user information
Other database monitoring solutions only provide OS shell account that was used
Do you have Privileged Users that use both generic DB accounts as well as generic OS accounts?
In many companies, users login with their OS account and then switch to a shell account that has the needed environment to access the database.
If they also use a generic database account,how do you track them back?!
Joe’s bumping his bonus!
Native auditing will only show you the DB Username
Other monitoring solutions can only show you the OS shell account that was used!
You need everything!
