Understanding HANA security

  HANA as a data mart   Similar to “classic” BW architecture, HANA gathers data from (several) source systems

  HANA in a classic 3-tier architecture   HANA replaces regular relational database

  HANA as a technical infrastructure for native applications   New business application platform (S/4 HANA)

Understanding HANA Security

HANA deployment scenarios

Content Considerations   Contains business critical data à espionage target

  Central to business processes à sabotage target

Technology Considerations   Fraud possibilities

  IT / Security has little experience with HANA

Understanding HANA Security Why is HANA important to Hackers

  HANA provides its own security functions

  Standard security features such as authentication, user/role mgt., authorization,

encryption…

  Need to be configured within HANA toolset

  Other mechanisms to integrate HANA into the general security infrastructure   Includes Standard SAP administration tools, Network, OS and DB security tools, etc.

  Different documents deal with HANA security, e.g. HANA security overview, HANA security admin guide, SQLScript-Reference-guide

Understanding HANA Security

What SAP says about HANA security

Security complexity rises with SAP HANA !

New risks in SAP HANA

Weaknesses can include XSS, SQL injection, Directory Traversal

Risk #1: Web Applications

SAP HANA systems can easily be found on the Internet

Unauthorized access possible

Services can be misused

SAP HANA is still vulnerable to typical web weaknesses

Be aware of risks in privileged functions, preventing OS command execution, etc.

Risk #2: R-Serve

R is used for statistical and advanced data analysis

SAP HANA can be connected to R-Serve to utilize R functions

For separate hosts, remote functions enabled

Make sure server-side scripting is protected against any injection attack

Risk #3: RAM scraping

HANA makes RAM scraping attractive for hackers Leaves almost no footprint

Circumvents encryption

Data on SAP HANA is not encrypted on RAM level

ABAP programming needs to be validated for weaknesses

Risk #4: Custom Development

SAP HANA applications are accessible through browsers

ABAP is still used for HANA in a 3-tier or data mart scenario

Increased development complexity

Web applications need to be secured at all levels

Risk #5: Basis security

Reality: SAP HANA runs in parallel to existing systems

SAP HANA includes separate security functions

Basic security features to be considered

Increased system landscape complexity with HANA means more security settings to keep in mind

5 rules to protect SAP HANA

Rule #1: No surprise: User and role management

Secure standard users (SYSTEM, <sid>adm, etc.)

Restrict authorizations

Use Single Sign-On

Strong Password Policies

Extensive privileges compromise the entire system !

Rule #2: Obviously: Data encryption and security

Encrypt all sensitive data (encryption is disabled by default on SAP HANA)

Encrypt at all levels (data at rest, secure store in the file system)

Establish key management procedures

Encryption effectively minimizes data theft !

Rule #3: Remember: Secure application development

Avoid http exposed packages

Use standard authentication methods

Follow development guidelines

Validate custom application security

Your code – your responsibility !

Rule #4: Don’t forget: Harden System settings

Ensure OS system security

Validate all other (HANA) system security settings

Secure communications for all connections

Restrict access wherever necessary

Monitor all security settings – configuration drift is a real challenge !

Rule #5: Not to mention: Enable auditing and logging

Enable audit log

Restrict audit authorizations

Secure access to audits and logs

Auditing enables a forensic analysis in case of an attack !

Security, Compliance and Quality Solutions

  HANA can be an attractive target for hackers

  Many known and new risks apply to HANA   Web applications

  R-Serve

  RAM-Scraping

  Custom developments

  Complexity of SAP system landscapes increases with additional HANA scenarios

  For an optimal use of HANA, many settings need to be adjusted
