What is the primary purpose of warning banners in corporate networks?

• A. To prevent unauthorized access
• B. To inform employees that monitoring may occur
• C. To block monitoring
• D. To preserve bandwidth

Answer: (B)

Warning banners in corporate networks exist to alert users that their activity on the network may be monitored and recorded. This notice helps set expectations, supports policy compliance, and provides a basis for monitoring and audits if misuse occurs. It also can strengthen deterrence because users know their actions are subject to logging and review. The banners themselves aren’t a technical barrier to access, nor do they actively block monitoring or manage bandwidth; those are handled by other controls and policies.
