Introduction

The CSSLP™ Professional Certification is designed to establish an industry standard and credential that attests to the holder's knowledge and ability to apply best practices in delivering secure software. The certification is language neutral and focuses on professionals whose work is related to the software life cycle, including software architects, software engineers, developers, programmers, project managers, quality assurance testers, and analysts.

The impetus behind the CSSLP certification is the ever-increasing losses incurred by all types of organizations from both insider and outsider attacks because of software that is not secure. Also, because of the increased exploitation of software vulnerabilities, additional regulatory and compliance requirements are being imposed by governmental bodies.

Secure software controls should be an integral part of the software life cycle, from conception to disposal, and should address the fundamental security concepts of confidentiality, integrity, availability, authentication, authorization, and auditing.

CSSLP Domains

As defined by (ISC)², the domains comprising the CSSLP Common Body of Knowledge (CBK^®) are:

Secure software concepts—Security implications in software development
Secure software requirements—Capturing security requirements in the requirements gathering phase
Secure software design—Translating security requirements into application design elements
Secure software implementation/coding—Testing for security functionality ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
