Question
Which one of the following security controls is most effective against zero-day attacks?Implement secure by designtrust but Always verifyVulnerability scansIntrusion prevention systems
Solution
The most effective security control against zero-day attacks among the options provided is "Trust but Always Verify".
Here's why:
-
"Implement Secure by Design": This is a proactive approach to security that involves designing the system to be secure from the ground up. However, it may not be effective against zero-day attacks because these attacks exploit unknown vulnerabilities that were not considered during the design phase.
-
"Trust but Always Verify": This approach involves continuously checking and validating even the trusted systems or processes. This can help in detecting any unusual activities or changes that might indicate a zero-day attack. Therefore, it is considered the most effective control against zero-day attacks among the given options.
-
"Vulnerability Scans": These are automated scans that identify vulnerabilities in a system. While they are an important part of any security strategy, they are not effective against zero-day attacks because these attacks exploit vulnerabilities that are unknown and therefore not included in the vulnerability databases used by the scanners.
-
"Intrusion Prevention Systems": These systems monitor network traffic to detect and prevent vulnerabilities. However, like vulnerability scans, they rely on known vulnerabilities and therefore are not effective against zero-day attacks.
