What threat do system administrators pose to network security?

System administrators possess elevated privileges and access that allow them to manage and configure network systems. While this access is essential for maintaining network functionality, it also creates a significant risk if not managed properly. One of the key threats posed by system administrators is the potential for misuse of this access. If an administrator chooses to act maliciously or if they inadvertently make mistakes, they could compromise the security of the entire network.

For example, an administrator with access to sensitive data could intentionally leak information or mistakenly misconfigure systems, leading to vulnerabilities that could be exploited by external attackers. Furthermore, because administrators often have access to various critical systems, they could unintentionally create backdoors or fail to properly secure configurations, providing additional opportunities for security breaches.

The other options, while relevant to network security, do not inherently highlight the specific threat posed by system administrators. Access to systems is inherently a double-edged sword: it is necessary for system administration but also creates risk if not managed with strict protocols and oversight.
