The Agent Skills Directory

[COMMAND_EXECUTION]: The skill executes various system commands through shell scripts to perform audits and apply security settings. This includes the use of apt-get, ufw, iptables, and sysctl to manage system state and network security.
[PRIVILEGE_ESCALATION]: The hardening and auditing scripts require administrative privileges to access and modify sensitive system files, such as /etc/shadow, /etc/ssh/sshd_config, and various kernel parameters. These operations are necessary for the primary function of server hardening.
[DYNAMIC_EXECUTION]: The scripts/harden-system.sh script utilizes an eval command within a wrapper function (apply_change) to execute system modifications. Although the inputs to this function are hardcoded within the script's logic, the pattern of evaluating string arguments as shell commands is a dynamic execution technique.
