Overview of this book

Information security and risk management best practices enable professionals to plan, implement, measure, and test their organization's systems and ensure that they're adequately protected against threats. The book starts by helping you to understand the core principles of information security, why risk management is important, and how you can drive information security governance. You'll then explore methods for implementing security controls to achieve the organization's information security goals. As you make progress, you'll get to grips with design principles that can be utilized along with methods to assess and mitigate architectural vulnerabilities. The book will also help you to discover best practices for designing secure network architectures and controlling and managing third-party identity services.

Sometimes, we need to take a hands-on approach to provisioning, auditing, updating, and de-provisioning systems, for example, when we transition to newer technology or when we have findings from a penetration test that was undertaken by a third-party.

Additionally, in Chapter 6, Designing and Managing Security Testing Processes, we covered web application vulnerability scanners, network vulnerability scanners, SAST/ DAST, dependency scanning, and similar automated scans, which can provide actions into changes that need to be undertaken and upgrades that need to be performed.

The problem is, how do you ensure that the IT team understands the risks facing the organization and action the list of changes that need...
