Essential Guide to World-Class Incident Response Plans

Why You Need a Robust Incident Response Plan
In today's digital landscape, cybersecurity threats are inevitable. According to a report by Cybersecurity Ventures, the global damage costs due to cybercrime are expected to reach $10 trillion by 2025. This makes having a world-class Incident Response Plan (IRP) not just an option but a necessity.
Anatomy of a World-Class IRP
Identifying the Incident
The first step in any effective IRP is identifying the incident. According to the National Institute of Standards and Technology (NIST), an incident is a violation or imminent threat of violation of computer security policies, acceptable use policies, or standard security practices.
Incident Classification and Prioritization
Once an incident is identified, it needs to be classified and prioritized. A study by Ponemon Institute shows that the average time to identify and contain a breach is 280 days, costing companies an average of $3.86 million.
Incident Response Team
Having a dedicated Incident Response Team (IRT) is crucial. According to CSO Online, the team should consist of members from IT, legal, public relations, and operations.
Incident Analysis
The IRT should conduct a thorough analysis of the incident. Verizon's Data Breach Investigations Report suggests that 86% of data breaches are financially motivated.
Incident Mitigation Strategies
After analysis, the next step is to mitigate the incident. A report by IBM shows that companies with an incident response team that also extensively tests their incident response plan experienced $1.23 million less in data breach costs on average than those who didn’t have either in place.
Post-Incident Review
After the incident is mitigated, a post-incident review is essential. According to Forrester Research, companies that conduct a post-incident review save an average of 25% on incident response costs.

Case Study 1: Equifax Data Breach
The Equifax data breach in 2017 exposed sensitive information of 143 million consumers. A detailed analysis by KrebsOnSecurity revealed that the breach was due to a failure in implementing security updates.
Case Study 2: WannaCry Ransomware Attack
The WannaCry ransomware attack affected over 200,000 computers across 150 countries. Microsoft's post-incident report emphasized the importance of regular software updates.
