About

OSDefSec (Open Source Defensive Security) is about information and system security using open source software.

Security?

“The only truly secure system is one that is powered off, cast in a block of concrete and sealed in a lead-lined room with armed guards.” – Gene Spafford


“If you think technology can solve your security problems, then you don’t understand the problems and you don’t understand the technology.” – Bruce Schneier

Security is only a mere perception of what one believes is secure, cause "Everything is Vulnerable". It is all about adding layers and mitigating the chances of a security breach.
CIA triad, refered within the security industry, refers to security which needs to ensure Confidentiality, Integrity and Availability to a system.

So the real question is, How secure do you think your system is?

So?

OSDefSec's idea is to enlighten about security and mitigating techniques, in a cost effective way, using open source software. We like to bridge the huge gap in understanding of security, among those who are unaware.

If you are into System Administration, System Operations, IT support, Network Operation, Security Researcher, Security Team, Linux fan, etc, I believe that OSDefSec would be useful.

Who?

I am no security expert, and the articles are only to share what I have learnt. I believe that I am a good learner and love to learn every single day. I like to keep things very simple, and hope you think the same about my articles. I love FOSS(Free Open Source Software).
Hope you like my articles and feel free to write to us. I love to share about anything interesting.

What?

Expect my articles to be pure technical, and no theory. Theory is very boring. I love the powerful command line shell, and hence expect lot of screenshots, videos and code snippets.
