Why are software updates important for Internet security?

• A. They introduce new vulnerabilities.
• B. They slow down the system but do not affect security.
• C. They remove security features.
• D. They fix vulnerabilities that attackers could exploit, reducing the risk of attacks.

Answer: (D)

Keeping software up to date is about closing gaps that attackers could use to break in. When developers find a flaw, they release a patch to fix it. If these fixes aren’t applied, the system stays vulnerable to exploits that could lead to data theft, malware infection, or unauthorized access. Updates often also refine defenses and fix other security issues, making the whole system harder to compromise. The best choice captures this idea: updates fix vulnerabilities that attackers could exploit, reducing the risk of attacks. Other statements miss the point, since updates are designed to improve security, not introduce or remove it, and while updates can affect performance in some cases, their primary purpose is to strengthen protection.
