Great! This is a fantastic entry primer on security particularly for software engineers, though it also delves a bit into corporate IT (very Windows heavy for that part). It covers the basics of what and how to implement cryptography for passwords, audit and patch vulnerabilities, and even goes into the basics of preventing SQL injection. Read this if you are a web developer without a traditional comp-sci background to get through most of what you will need building basic applications. If you are well versed in networking and infrastructure or larger scale architecture, read this as a reminder that other more junior individuals in your organization may not have all these practices as rote quite yet.
