Cyber Disaster Recovery

Planning for the Inevitable


Slide2 l.jpg

20 years ago Disaster Recovery (D/R) plans protected brick and mortar companies. Today it must protect the growing virtual side of business: E-business.


Why focus on incident preparedness l.jpg
Why Focus on Incident Preparedness? and mortar companies. Today it must protect the growing virtual side of business: E-business.

  • 20 years ago, survival of the business depended on survival of the brick-and-mortar infrastructure

    • Earthquake and hurricane “proof” buildings

    • Redundant power and communications

    • Disaster recovery planning

    • Regulatory requirements

Overview l.jpg
Overview the

  • 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


Traditional disaster recovery l.jpg
“Traditional” disaster recovery the

  • Business impact analysis

    • Determine functional areas critical to the business

    • Identify critical computer systems and applications

    • Determine disaster recovery budget

  • Formal disaster recovery plan

    • Disaster declaration criteria and procedures

    • Hot-site and cold-site arrangements

    • Staff response / call-out plans

    • Recovery procedures

  • Annual testing


Cyber disaster recovery7 l.jpg
“Cyber” disaster recovery the

  • Business impact analysis

    • Focusing on impact of “electronic” disasters such as computer security breaches, instead of “natural” disasters

  • Computer Security Incident Response Plan

    • Similar in structure to disaster recovery plan

      • Incident declaration criteria and procedures

      • Staff response / call-out plans

      • Recovery procedures

    • Restore operations “in-place,” not at hot-site

    • Focus on forensic approach

    • Quarterly testing


An observation l.jpg
An observation… the

  • ISS responded to as many intrusion incidents in Q4-03 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.


What happened l.jpg
What happened? the

  • These incidents were not caused by “natural” disasters like fire, flood, or earthquake

    • A “traditional” disaster recovery plan would not have been sufficient

  • But the potential effects were the same

    • Ability to conduct business was impacted

    • Reputation could have been damaged

    • Financial loss could have occurred

    • Loss of customers


The need for good and timely information l.jpg
The need for good and timely information the

  • During a natural disaster, information is made available to us by television, radio, and government sources

  • During a cyber-disaster, we are almost always limited to the information we can obtain for ourselves

  • Planning and response are improved when we know ahead of time how these attacks work and how we can defend against them


Obtaining good and timely information l.jpg
Obtaining good and timely information the

  • 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?


Information security lifecycle l.jpg
Information Security Lifecycle the

How well are we protected, now and in the future?

What can we add or change to improve our security?

Put all this in place without impacting users

Given what we have, how do we handle security incidents?


Goals of an incident response l.jpg
Goals of an Incident Response the

  • 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


Incident response l.jpg
Incident Response the

  • 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.
