Question 29

Anya, a security analyst at a global e-commerce firm, is reviewing audit logs and detects a pattern of failed login attempts followed by a successful login to the customer database using credentials belonging to a recently terminated employee. The access originates from a VPN IP address with a reputation for anonymity. The company operates under strict data privacy regulations like GDPR and CCPA, which mandate robust protection of customer personally identifiable information (PII). Given this context, what is the most prudent immediate course of action for Anya to mitigate the potential impact of this security event?

Accepted Answer

Immediately block the originating IP address and escalate the incident to the Security Incident Response Team (SIRT) and legal counsel for further investigation and regulatory compliance.

Question 30

During a routine security audit, Elara, a senior security analyst, discovers that a critical intrusion detection signature, previously highly effective against a specific advanced persistent threat (APT) group, is now exhibiting a significantly higher rate of false negatives. This is attributed to the APT group\'s recent adoption of novel obfuscation techniques designed to bypass signature-based detection. The organization’s security posture is at risk, and the threat landscape is rapidly evolving, creating a high degree of ambiguity regarding the exact nature and scope of the current compromise attempts. Elara needs to recommend an immediate strategic adjustment to maintain effective threat detection and response capabilities. Which of the following actions best exemplifies Adaptability and Flexibility in this scenario?
