I have subscribed to numerous security lists, setup up2date/RHN, and have cpanel cron job to update other software. I also have daily, weekly, and monthly backups setup (local and remotely). Is their anything else I can do to tighten down security and safeguard? Can i turn off any of the ports listed below?
What is tcpmux, domain, sunrpc, unkown, rndc?
