Defensive Coding Practices
The course is part of this learning path
This course is the second course in our series covering domain 4 of the CSSLP certification and explores defensive coding practices and how they can help secure your software.
- Understand the foundations of defensive coding practices
- Learn about the primary threat mitigations that can be employed
- Understanding how we can learn from our mistakes in the context of software security
This course is intended for anyone looking to develop secure software as well as those studying for the CSSLP certification.
Any experience relating to information security would be advantageous, but not essential. All topics discussed are thoroughly explained and presented in a way allowing the information to be absorbed by everyone, regardless of experience within the security field.
So in looking at our primary mitigations, in general, we consider that a defense in depth approach should be developed and informed by design and data flow analysis, threat modeling, and similar techniques that begin with stage one in development projects. In other words, at the earliest point where we have a clear idea of what we're doing and where we're going, this sort of thing should be considered. We have to ensure that the planned working environment, of course, has been sanitized and hardened to the extent reasonable. We have to control both inputs and outputs to prevent inadvertent and advertent alteration.
The philosophy of trusting no one means that regarding all components and tools are going to be considered as untrusted until proven otherwise. Now using known and proven industry-standard good libraries and frameworks, and avoid using home-built constructions. We need to consider the integration of security requirements from the very beginning as has been a theme, and we should have a varied program of tests and methods intended to expose weaknesses and vulnerabilities in different ways to avoid blind spots and the inevitable tunnel vision.
