Overview n n n Traditional disaster recovery (D/R) planning is formal and tested regularly Cyber-D/R planning is less mature, but more necessary today Cyber-D/R requires quick reaction and different skill sets: e. g. , computer forensics Growing trend toward prosecution Critical infrastructure protection requires better Cyber-D/R planning and response capability © 2004 Internet Security Systems.

An observation… n n n ISS responded to as many intrusion incidents in Q 4 -03 alone as it did all of 2003. 75% of the cases have requested forensic evidence considerations for prosecution. These incidents were all different, but they have had recurring themes which make them easier to prepare for. © 2004 Internet Security Systems. All rights reserved.

What happened? n These incidents were not caused by “natural” disasters like fire, flood, or earthquake n n A “traditional” disaster recovery plan would not have been sufficient But the potential effects were the same Ability to conduct business was impacted n Reputation could have been damaged n Financial loss could have occurred n Loss of customers n © 2004 Internet Security Systems.

The need for good and timely information During a natural disaster, information is made available to us by television, radio, and government sources n During a cyber-disaster, we are almost always limited to the information we can obtain for ourselves n Planning and response are improved when we know ahead of time how these attacks work and how we can defend against them n © 2004 Internet Security Systems. All rights reserved. Contents are property of Internet Security Systems.
Obtaining good and timely information n n n Do you have skills in-house to stay on top of threats and vulnerabilities? Does your staff respond to attacks frequently enough to keep their skills sharp? Do you have ( and follow) escalation, notification and handling procedures? What is the value of a second opinion when you think you’re under attack? Can you conduct a forensic investigation without contaminating evidence? What are your regulatory requirements? © 2004 Internet Security Systems. All rights reserved.

Goals of an Incident Response n n n n Gain control of any upcoming security problems Facilitate centralized reporting of incidents Coordinate response to incidents Raise security awareness of users Provide a clearinghouse of relevant computer security information Promote security policies Provide liaisons to legal and criminal investigative groups both inside and outside the company © 2004 Internet Security Systems.

Incident Response • Detection: Analysis of incident data to determine the source of the incident, its cause (program error, human error, or deliberate action), and its effects; • Containment: Preventing the effects of the incident from spreading to other computer systems and computer communications networks in your organization; • Eradication: Stopping the incident at the source and/or protecting your computer systems and computer communications networks from the effects of the incident; • Recovery: Restoration of the affected computer systems and computer communications networks to normal operation; and • Risk Reoccurrence Mitigation: Making sure that your computer systems and computer communications networks are protected from future occurrences of the incident. © 2004 Internet Security Systems.
