Defensive Security Handbook 2nd Edition (5th Early Release)

Despite the increase of high-profile hacks, record-breaking data leaks, and ransomware attacks, many organizations don't have the budget for an information security (InfoSec) program. If you're forced to protect yourself by improvising on the job, this pragmatic guide provides a security-101 handbook with steps, tools, processes, and ideas to help you drive maximum-security improvement at little or no cost.

Each chapter in this book provides step-by-step instructions for dealing with issues such as breaches and disasters, compliance, network infrastructure, password management, vulnerability scanning, penetration testing, and more.
