Open Source Vulnerability Database

The open source community has long been fueled by the drive and
inspiration of those wishing to produce software for the good of
everyone. Open source allows its users to achieve things that would
have otherwise not been possible. Often, proprietary software is too
expensive, not flexible, and full of bugs. Users of proprietary
software work at the mercy of their vendors with little to no influence
on features or functionality. Those organizations who demand security
often have trouble getting proprietary software vendors to comply. Open
source is a great solution for those wishing to have complete control
including over security, flexibility, and functionality.

Open source thrives on those wishing to share their work for the
benefit of the community. To have a successful open source project, it
must be backed by individuals who are ultimately committed to the
project. Contributors must be willing donate time and money for the
advancement of the cause. Often, open source projects are not properly
funded until they are already well established.

Recently, I
have had the great pleasure of talking with Tyler Owen, a contributor
to the Open Source Vulnerability Database project. He, and others
associated with the project have shown a lot of initiative. Although it
has been slow getting off the ground, there has been a renewed
commitment to provide the open source community with a database that
indexes security vulnerabilities. Rather than individual open source
users being burdened with keep track of them, OSVDB is striving for it
to be a more collaborative process so that work is not duplicated and
everyone can benefit.

Digital Launches Next Generation Secure Mail Suite
Guardian Digital, the premier open source security company, announced
the availability of the next generation Secure Mail Suite, the
industry's most secure open source corporate email system. This latest
edition has been optimized to support the changing needs of enterprise
and small business customers while continually providing protection
from the latest in email security threats.

and National Security
- As the open source industry grows
and becomes more widely accepted, the use of Linux as a secure
operating system is becoming a prominent choice among corporations,
educational institutions and government sectors. With national security
concerns at an all time high, the question remains: Is Linux secure
enough to successfully operate the government and military's most
critical IT applications?
