Question

Why would you reduce TCP session timers?

a) Increase security
b) Improve performance
c) Enhance memory usage
d) Extend session lifespan

Answer 1

Reducing TCP session timers mainly enhances memory usage by freeing up resources for active connections and helping prevent resource exhaustion during DoS attacks.

Step-by-step explanation:

Reducing TCP session timers can primarily enhance memory usage on a network device. By decreasing the duration that inactive sessions remain in the device’s memory, more resources become available for new or active sessions, which is beneficial in environments where memory resources are limited. This reduction can help in mitigating the effects of Denial-of-Service (DoS) attacks, as fewer resources are consumed by idle or half-open connections. Although shortening TCP session timers may have some impact on performance, increasing security and extending session lifespan are not the primary reasons for this adjustment.
