What is the primary hazard posed by worms?

1. They can change network configurations

2. They replicate quickly and spread without human intervention

3. They require human action to proliferate

4. They are less likely to be detected

The correct answer is: They replicate quickly and spread without human intervention

Worms are a type of malicious software that stand out primarily due to their ability to replicate and spread automatically across networks without the need for human intervention. This characteristic is what makes them particularly dangerous, as they can exploit vulnerabilities in operating systems or software to propagate rapidly from one computer to another. Unlike other types of malware that may require users to unknowingly assist in their propagation (such as opening an infected email attachment), worms autonomously seek out and infect other machines, leading to widespread infections in a short period. This can result in significant damage, including network congestion, performance issues, and potential data breaches. This automatic replication and spreading capacity distinguish worms from other malware types, which may rely more on user action or specific conditions to spread. Understanding this critical trait is vital for network security professionals as they develop strategies to defend against such threats.
