Patching and upgrading software requires more than running a few commands. Having a patch recovery plan, communicating with developers on that server, and knowing who to contact in case of a botched patch job is critical.

Just to give everyone an idea about who writes these articles and feature stories that we spend so much of our time reading each day, I have decided to ask Brian Hatch and Duane Dunston, the newest members of the LinuxSecurity.com team, a few questions.

Maintaining accurate time is required for security. Many tools and devices exist to ensure that accurate time is maintained on an organization's system. It makes the job of analysis and system administration much easier to deal with, as well.

Attackers are still compromising servers with well-known attacks. General awareness can assist the busy administrators and users to protect their systems from these kinds of attacks. SANS provides a list of the Top 20 most common security vulnerabilities, how to identify each, and what can be done to protect against these vulnerabilities.

The question of the week: What is Slapper? Let me begin by telling you I am not only describing the Slapper worm, but I am also describing the Apache/mod_ssl worm, the bugtraq.c worm, and the Modap worm. In effect, this is just 4 different names for the same nasty worm.

NFS Security

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

NFS (Network File System) is a widely used and primitive protocol that allows computers to share files over a network. The main problems with NFS are that it relies on the inherently insecure UDP protocol, transactions are not encrypted and hosts and users cannot be easily authenticated. Below we will show a number of issues that one can follow to heal those security problems.
