  • Security Information and Event Management (SIEM): Use SIEM systems to aggregate and analyze security logs.

Incident Response Plan

Develop a robust incident response plan to address data breaches and security incidents promptly.

  • Preparation: Establish clear procedures and responsibilities for incident response.
  • Detection and Analysis: Quickly identify and analyze security incidents.
  • Containment and Eradication: Contain the incident and eliminate the root cause.
  • Recovery and Lessons Learned: Restore affected systems and review the incident to improve future response efforts.
