New Threats to Federal IT Systems

5

Dark and Stormy forecast for Federal networks• In March 2011 24,000 documents exfiltrated from Pentagon

contractor

• Elaborate attack against RSA results in loss of millions of secret seeds for tokens

• Ensuing attacks against Lockheed Martin, Grumman and L3

• IMF losses

• Hacker attacks against Senate.gov, CIA.gov

Something needs to change• Threat is there, now what do we do?

How to Reorganize Federal IT

8

Advocate bottom-up rather than top-down change

•Pentagon’s just published Strategy for Operating in Cyberspace is yet another example of top down strategy documents.

•Expect similar results to the Comprehensive National Cybersecurity Initiative, Presidential Directives, and Cyberspace Policy Review.

8

Pentagon Strategy for Operating in Cyberspace 15, July 2011• Strategic Initiative 1: Treat cyberspace as an operational domain to organize,

train, and equip so that DoD can take full advantage of cyberspace’s potential.

• Strategic Initiative 2: Employ new defense operating concepts to protect DoD networks and systems.

• Strategic Initiative 3: Partner with other U.S. government departments and agencies and the private sector to enable a whole-of-government cybersecurity strategy.

• Strategic Initiative 4: Build robust relationships with U.S. allies and international partners to strengthen collective cybersecurity.

• Strategic Initiative 5: Leverage the nation’s ingenuity through an exceptional cyber workforce and rapid technological innovation.

Organizing for cyber defense

• There is no strategy without responsibility

• Create a separate unit to address targeted attacks

10

Introducing the cyber defense team

Cyber Commander

Analysts Operations Red Team

11

Cyber Commander• Assigns and directs roles

• Makes sure the correct tools and defenses are deployed

• Puts in place controls and audit processes

• Reports to upper management on the results of those processes and audits

• Primary point of contact for communicating to law enforcement and intelligence agencies

12

Analysts

Cyber defense analysts study the threat landscape and gather intelligence on emerging threats.

• Understanding the state of the art in attack methodologies.

• Getting to know potential attackers and monitoring their activity.

• Monitoring known attack sources.

• Communicating the threat level to the rest of the cyber defense team.

• Assisting in evaluating technology for internal deployment.

13

Operations

• Selecting and deploying tools

• Discovering internal infections

• Monitoring insider behavior

14

Red Team

• Attack and penetration

• Internal audit

• Operates outside the realm of operational vulnerability assessment. They thrive on social engineering.

15

16

Next steps

• Repeat cyber command structure in every agency / department

• Create overarching cyber command

16

17

Elements of a defensive strategyHarden networks and end points against targeted attacks:

1.Complete packet inspection inbound and outbound

2.Whitelisting on servers, desktops, and embedded systems

3.Platform diversity (Do not, for instance, run Windows on control systems)

4.User behavior monitoring

17

The attackers have changed their tools, targets, and goals.

The defenders must change too.

Examining Key Security Approaches

1. Implement Defense-in-Depth Endpoint Security

2. Shift from Threat-Centric to Trust-Based Security

3. Build a bottom up approach with operational excellence focused on “the basics”

Three Defensive Strategies

Strategy 1: Defense-in-Depth

Unauthorized•Games•iTunes

Unknown• Viruses• Worms• Trojans• Keyloggers• Spyware

Flexible Trust

Trusted Publisher• Authorizes applications based on the vendor that “published” them through

the digital signing certificate.

25

Trusted Updater• Authorizes select systems management solutions to “update” software, patches

and custom remediations, while automatically updating them to the whitelist.

Trusted Path• Authorizes applications to run based on their location.

Local Authorization• Allows end-users to locally authorize applications which have not been otherwise

trusted by the whitelist or any other trust rules.

25

Strategy 3: Operational Excellence – “The Basics”

26

Assess Prioritize Remediate Repeat• Identify all IT assets (including platforms, operating systems, applications, network services)

• Monitor external sources for vulnerabilities, threats and intelligence regarding remediation

• Scan all IT assets on a regular schedule for vulnerabilities, patches and configurations

• Maintain an inventory of IT assets

• Maintain a database of remediation intelligence

• Prioritize the order of remediation as a function of risk, compliance, audit and business value

• Model / stage / test remediation before deployment

• Deploy remediation (automated, or manually)

• Train administrators and end-users in vulnerability management best practices

• Scan to verify success of previous remediation

• Report for audit and compliance

• Continue to assess, prioritize and remediate

Stop Unwanted Applications

»Immediate and simple risk mitigation

27

Denied Application Policy prevents unwanted applications even if they are already installed

Easily remove unwanted applications

Reducing Local Administrator Risk

»Limit Local Admin Usage»Monitor and Control existing Local Admins
