Open Letter to Linux Security Community
Welcome to the new LinuxSecurity.com! I must admit, I am really
proud of what we have been able to accomplish over the years.
LinuxSecurity.com has grown from a small idea that a couple of
security geeks had in 1999, to a major and well respected Linux
resource. With an all new look & feel, organizational changes,
security events, and additions to our staff, we hope to better
serve the Linux and open source community. Although there are
many aesthetic improvements, a major part of our development
has focused on creating a content structure and backend
system that is easy to update.
Since the beginning, we have been able to maintain one of the
largest, if not the largest and most comprehensive Linux
advisory archive on the Internet. Through the years, we have
scoured the net for thousands of hours to bring fresh and
relevant articles, papers, and resources to you. It wasn't easy
in the beginning. We had to create the site from scratch and
build a community-wide reputation. The site was started in 1999,
the middle of the dot-com boom. Dave Wreski, a Linux security
expert and the original founder of LinuxSecurity.com had great
foresight. He envisioned the widespread use of Linux as well as
many other open source tools. Rather than companies spending
thousands of dollars on proprietary tools, he saw a world
where open source would be respected and adopted because of its
flexibility and greater security through open standards and
full disclosure...

Mass deploying Osiris
Osiris is a centralized file-integrity program that uses a
client/server architecture to check for changes on a system.
A central server maintains the file-integrity database and
configuration for a client and at a specified time, sends the
configuration file over to the client, runs a scan and sends
the results back to the server to compare any changes. Those
changes are then sent via email, if configured, to a system
admin or group of people. The communication is all done over
an encrypted communication channel.

AIDE and CHKROOTKIT
Network security is continuing to be a big problem for companies
and home users. The problem can be resolved with an accurate security
analysis. In this article I show how to approach security using aide
and chkrootkit.
