Disable the Source Packet Routing
In a network, source routing allows the sender to specify some or all routes for data packets to pass through the network. In regular routing, routers in the network determine the path based on the destination of the data packets. If a large number of packets are tampered with and pass through th...
Ensure That Soft and Hard Link Protection Is Correctly Configured
In Linux, a soft or hard link is a file pointing to another file target. In other words, the target is opened once the link file is opened. Therefore, an attacker can forge a soft link as a common user for a privileged user to execute, causing security issues such as privilege escalation. The sam...
