The correct choice highlights significant threats that corporate servers face in a security context. Theft and fraud are critical concerns for organizations, especially those with valuable data assets. Corporate servers often contain sensitive information such as customer data, financial records, and proprietary software. The risk of theft can manifest through various methods, including unauthorized access to servers or networks, leading to data breaches where hackers exploit vulnerabilities to steal sensitive information.

Fraud can occur internally or externally; for instance, individuals may manipulate data or exploit systems to gain financial advantage or sabotage operations. Organizations must implement strong security measures, such as access controls, encryption, and constant monitoring, to mitigate these risks and protect their data integrity.

In contrast, while options related to viruses, taps, and data alteration represent real threats, they fall under broader categories of security challenges and do not specifically denote the direct impact of theft and fraud, which have profound implications on trust and financial loss within corporations.
