Description-en: basic system security checks
Checksecurity can periodically do some very basic system security checks:
.
* check-setuid - scans for insecurely mounted remote file systems,
and tracks changes in setuid programs;
* check-sockets - tracks changes in open ports to detect rogue programs;
* check-passwd - scans for empty or duplicate system accounts;
* check-disfree - scans for mounted filesystems nearing capacity;
* check-iptables-logs - scans logs generated by iptables and look
for intrusion attempts.
.
Be aware that these minimal set of checks are no substitute for a full
security auditing and integrity checking system.
.
In addition to these checks you are encourage to install additional packages
(listed in "Recommends") to provide more information concerning the security
or vulnerability of your system.
.
Installing the suggested package lockfile-progs can help to prevent
the cron jobs running multiple times if something gets jammed.
