Take-Aways

• Nature of attacks has changed• Law enforcement, judiciary not

prepared• Failure of traditional incident

response• Agile incident management• Computer Security and

Incident Response Teams, CSIRTs – moving to SMEs


"Fools you are . . . who say you like to learn from your mistakes ... I prefer to learn from the mistakes of others, and avoid the cost of my own.“ O. v Bismark

The Threat Has Changed

• Attackers financially motivated – skills are rewarded; “business competitors” are hacking

• “Trickle down effect” – powerful, easy to use tools are widely available

• Opportunistic, automated attacks• Targeted (social engineering; HBGary,

Government)• Persistent agents


Law Enforcement …

• 61,000 police officers in Canada• 245 specialize in cybercrime (0.4%)• Overall, lack budget and training• Still developing legal infrastructure to

support criminal investigations (lawfulintercept legislation)

• In short, an effective response is generally up to the victim

• Are you ready? …


Data Security Incidents

Non-compliance with the corporate security policy or procedures, or any

event that negatively impacts the confidentiality, integrity and availability

of your corporate data


“Traditional” Incident Response

• Event-triggered: you have lost the initiative• Competing priorities – technical (investigation)

versus business (recovery) • Mistakes are frequent


The Failure of Traditional IR - 1

Corporate• Tactical, short-term perspective• Competing priorities – business

versus technology• Poorly defined roles and responsibilities• Failure to support technical personnel• Corporate secrecy (external entities)• Failure to learn from previous incidents; no

formal method to create a corporate memory (internal)


The Failure of Traditional IR - 2Technical• Technical staff lack contacts,

communications skills for dealing with management, externals

• Failure to provide comprehensive response (legal, HR, etc)

• Focus on the technology; can lose sight of the business

• Difficult to deal with privileged users (system administrators, database admins)

• Difficult to deal with internal attackers© 2010 Digital Defence. All rights reserved. This document is for informational purposes

only. Digital Defence makes no warranties, express or implied, in this document.

The Failure of Traditional IR - 3Technical• Unable to keep up with methodology

and tools of attackers (encryption, anti-forensics, live response)

• Lack of “appropriate” training (scenario-based technical training, current attacks, soft skills)

• Lack tools for effective incident response• Not all problems have a technical solution!


Agile Incident Management

Incident management is the totality of proactive and reactive measures

undertaken to help prevent and manage data security incidents

across an organization

CSIRT

Computer Security and Incident Response Teams, CSIRTs• Types:

– National-level– Specific verticals (critical infrastructure)– Universities– Vendors– Businesses

• Multi-dimensional team focused on responding to all possible security incidents – (IT, security, HR, PR, physical security,

business owners, legal …)

Computer Security and Incident Response Teams, CSIRTs• Formal teams

– 5 – 10 members– 24x7 availability– Well trained – High-stress roles,

burn-out is common

• Require committed support of large organizations to gain benefits


Moving the CSIRT “Down the Chain”

• Bring CSIRT to SMEs• Change perspective:

– “First responders” are the end users

– CSIRT responds to incidents (“triage”)

– Collect and preserve evidence– Manage internal, external relationships– Maintain corporate memory


Agile CSIRTs – Reliance on 3rd Parties

• 3rd parties (“partner sourcing”)• Technology audits, assessments, evaluation,

certification• Alerts, warnings• Repository of documentation, tools, techniques• Post-event analysis – the “post mortem” • Education and training• Metrics and benchmarking• External validation of team and

processes© 2010 Digital Defence. All rights reserved. This document is for informational purposes only. Digital Defence makes no warranties, express or implied, in this document.

Agile CSIRTS – Key Success Factors• What are your core CSIRT functions?• Defined and documented roles, responsibilities• Business and technical functions represented• Access to tools

– Open source, proprietary • Access to information

– Similar organizations– Security warnings, briefings, CSIRTS– Law enforcement


Agile CSIRTs – Key Success Factors

• Training– Seminar, boot-camp– Scenario-based

• Risk assessment based – what do you need?– Ethical hacking– Incident response techniques– Malware analysis– Data forensics (live systems, static forensics)– Criminal and intellectual property law
