Top 6 Cyber Incident Response Plans - 2024
#cybersecurity #incidentresponse #IRplan #preparation #identification #containment #eradication #recovery #lessonslearned
Modern security tools can protect networks, but incidents still happen.
Security teams need the right tools and knowledge to respond effectively.
SANS Institute defines a framework with six steps to a successful incident response.
Preparation, identification, containment, eradication, recovery, and lessons learned.
Training, logging, and technology are important aspects of preparation.
Identification involves detecting breaches and collecting IOCs.
Containment minimizes damage and requires clear plans.
Eradication involves completely removing threats and documenting the process.
Recovery brings operations back to normal and includes ongoing monitoring.
Lessons learned should be documented and used to improve capabilities.
Keep more logs, model attacks, train people, and consider an external investigation team.
