In the preparation stage, it's essential not only to establish incident handling capabilities but also to protect against incidents.
While the incident handling team focuses on response, protection-related activities are crucial for understanding incident types and sophistication, aiding investigations.
Highly recommended protective measures include technologies like SPF, DKIM, DMARC for email security, endpoint hardening with EDR, network segmentation, and privilege management.
- DMARC, an email authentication protocol, enhances email security by rejecting fraudulent emails.
- Endpoint Hardening and EDR technologies monitor and respond to threats on devices in real-time.
- Network Protection involves segmentation and IDS/IPS implementation. Privilege Identity Management, MFA, and strong password practices safeguard against credential theft.
- Vulnerability Scanning and User Awareness Training are critical for proactive security.
- Active Directory Security Assessments and Purple Team Exercises further strengthen security posture.
These exercises involve training incident handlers, performing security assessments, evaluating defensive capabilities, testing incident response playbooks, and improving detection and response mechanisms.
Thorough preparation and protective measures are key to mitigating cybersecurity risks effectively.
