Certified Incident Handler (CIH) Practice Ecam

Which practice is effective for eradicating email security incidents in an organization?

1. Block other unrelated emails

2. Identify common patterns and block them

3. Ignore spam reports

4. Monitor only outgoing emails

The correct answer is: Identify common patterns and block them

Identifying common patterns and blocking them is a highly effective practice for eradicating email security incidents in an organization because it allows for a proactive approach to dealing with threats. By analyzing past incidents, organizations can pinpoint the characteristics shared by malicious emails, such as specific keywords, sender addresses, or file types. Once these patterns are identified, implementing automated filtering rules to block emails that fit these criteria significantly reduces the risk of similar incidents occurring in the future. This systematic approach not only minimizes the chances of harmful emails reaching users but also helps in creating a reinforced security posture against evolving threats. As cybercriminals often reuse techniques and tactics, maintaining vigilance in identifying and blocking malicious patterns can adaptively respond to new threats as they emerge. In contrast, blocking unrelated emails could hinder legitimate communication and might not specifically target the actual issue at hand. Ignoring spam reports fails to engage with potential threats and misses opportunities for learning and adaptation. Monitoring only outgoing emails would overlook incoming threats, which are often the primary source of security incidents related to email. Therefore, focusing on identifying and blocking common malicious patterns is the most effective strategy for enhancing email security within an organization.
