Guide on cyber incident response: skills, frameworks, real-world examples, and the OffSec advantage for building cyber resilience.
4 min read
The proliferation of new cyber threats has made incident response harder and more important. What’s clear is that incident response isn’t something that can be 100% automated. Today’s incident responders need to be equipped with a diverse set of skills including rapid detection, containment, eradication and recovery when faced with a security breach, as well as two real-world examples of incident response.
Effective incident response requires a proactive mindset focused on readiness. The key is having defined plans, skilled personnel, and tested processes in place before an event occurs. This enables organizations to swiftly detect incidents, understand the impact, contain threats, eliminate footholds, and restore operations. Below, we’ll be briefly going over core incident response frameworks, incident response team roles, the incident response lifecycle, and how having the OffSec advantage helps organizations stay safe.
Most organizations utilize established frameworks to structure their incident response capabilities. Below are a few examples of frameworks used in enterprise organizations today to maximize incident response capabilities:
NIST 800-61: Provides guidelines for building IR teams, communication plans, monitoring, analysis, mitigation, reporting, and improvements.
SANS IRP: Outlines a six-step process including preparation, identification, containment, eradication, recovery, and lessons learned.
MITRE ATT&CK: Maps out known adversary techniques to inform detection strategy and response capabilities.
Cross-functional collaboration is crucial for security incident response. The effectiveness of incident response hinges on a well-coordinated team, each member playing a pivotal role:
This collective expertise is the driving force behind an organization’s incident response lifecycle, which, when implemented correctly, ensures a strategic and comprehensive approach to every phase of incident management.
In the realm of cybersecurity, the Incident Response Lifecycle is a critical narrative of defense, unfolding in phases, each crucial to thwarting cyber threats effectively.
This lifecycle not only prepares organizations to face current threats but also to learn from past incidents like the two outlined below, turning each challenge into a stepping stone towards greater cyber resilience.
In the theater of cyber conflict, certain narratives stand out, serving not just as lessons but as catalysts for evolving our defense strategies. The SolarWinds and Colonial Pipeline incidents are such stories, each offering unique insights into the fabric of robust incident response.
A covert operation turned the trusted SolarWinds Orion platform into a conduit for a massive breach, affecting top-tier organizations. The incident underscored the essentiality of robust monitoring and quick, decisive action in incident response. It taught us that vigilance and a proactive stance in detecting and isolating threats are fundamental in mitigating the impact of a breach.
The Colonial Pipeline incident, a dramatic ransomware attack, disrupted critical infrastructure and market dynamics. However, the swift containment, collaboration with law enforcement, and strategic recovery efforts highlighted the power of a resilient incident response. This story reinforces the importance of preparation, rapid action, and clear communication in turning the tide against cyber threats.
The above narratives are not just cautionary tales but blueprints for building a resilient future. They emphasize that a robust incident response is our most reliable shield against the evolving threats in the cyber realm. As we forge ahead, let’s carry forward these lessons, integrating them into our strategies for a more secure digital world, and consider how OffSec’s continuous workforce development platform can help.
