Thank you for reading the Linux Advisory Watch Security Newsletter. The purpose of this document is to provide our readers with a quick summary of each week's vendor security bulletins and pointers on methods to improve the security posture of your open source system. Vulnerabilities affect nearly every vendor virtually every week, so be sure to read through to find the updates your distributor have made available.

LinuxSecurity.com Feature Extras:

- Social engineering is the practice of learning and obtaining valuable information by exploiting human vulnerabilities. It is an art of deception that is considered to be vital for a penetration tester when there is a lack of information about the target that can be exploited.

- When you’re dealing with a security incident it’s essential you – and the rest of your team – not only have the skills they need to comprehensively deal with an issue, but also have a framework to support them as they approach it. This framework means they can focus purely on what they need to do, following a process that removes any vulnerabilities and threats in a proper way – so everyone who depends upon the software you protect can be confident that it’s secure and functioning properly.
