← Logic & PuzzlesIf an engineer modifies a regular expression used for packet filtering in a network firewall to accept a broader range of patterns, which consequence follows?
A)Decreased computational resource utilization
B)Reduced risk of denial-of-service attacks
C)Increased network security vulnerability✓
D)Improved data compression efficiency
💡 Explanation
Increased network security vulnerability results because a broader regular expression means more packets are accepted, which reduces the filtering stringency, therefore increasing the risk of malicious traffic passing through rather than blocking it. Less restrictive expressions do not inherently improve compression or reduce resource use.
