CWE List & CERT Secure Coding Standards — An Overview
Up to problems are caused by coding errors.
That’s why secure coding is more important than ever before. There are several secure coding practices you can adopt today. But to write truly secure code, you need a .
What Are Secure Coding Standards?
Secure coding standards are rules and guidelines used to prevent security vulnerabilities. Used effectively, secure coding standards prevent, detect, and eliminate errors that could compromise software security.
Why Secure Coding Guidelines Are Important
guidelines are important for every development team. And they're especially important for the C and C++ programming languages.
C and C++ are the preferred languages for embedded development — where safety and security is critical. That’s because they’re flexible, high-performance languages. But flexibility and performance come with a cost — risk.
So, embedded developers need to write secure code in C and C++.

CWE Security Weakness List
The Common Weakness Enumeration (CWE) list identifies software security weaknesses in C and C++. The CWE list is compiled based on community feedback. It’s sponsored by the MITRE corporation.
The latest version of CWE — CWE 3.1 — was released in 2018.
The CWE security weakness list includes over 600 categories, such as:
- Buffer overflows
- Cross-site scripting
- Insecure random numbers
So, you can use this list to identify potential weaknesses in your code. Using a static analyzer, such as Helix QAC, helps you identify CWE security weaknesses faster.
CWE Compliance With Perforce Static Analyzers
Perforce's static analyzers — Helix QAC and Klocwork — can check your code against the CWE list of security weaknesses automatically. Both Helix QAC and Klocwork can be used for compliance with CWE C and CWE C++. In addition, Klocwork can also be used in compliance with CWE C# and CWE Java.
What's more, both of Perforce's static analyzers report on the results of code analysis in terms of CWE compliance.
CERT Security & Secure Coding Rules
CERT is a secure coding standard. It’s developed by the CERT division of the Software Engineering Institute at Carnegie Mellon University. This secure coding standard is available for C and C++.
CERT targets insecure coding practices and undefined behaviors that lead to security risks. Using CERT security rules will help you identify security issues in existing code and prevent the introduction of new issues that pose a security risk.
You can apply CERT secure coding rules faster by using a static analyzer, such as Helix QAC.
CERT Compliance With Perforce Static Analyzers
Perforce's static analyzers — Helix QAC and Klocwork — can check your code against CERT C and C++ coding standards. CERT security rules improve the safety and quality of your code. And, both of Perforce's static analyzers automatically checks your code against CERT’s secure coding rules.
This module supports the 2016 editions of CERT C and CERT C++ coding standards.
CWE vs. CERT vs. MISRA
There are overlaps between secure coding standards. For instance, the CERT C and C++ coding standards address many of the CWE weaknesses.
includes two addenda focused on security. These map MISRA C’s rules against CERT C and ISO/IEC TS 17961:2013 “C Secure”.
You can apply MISRA C security rules faster with Helix QAC.
MISRA Compliance With Helix QAC
The MISRA compliance modules for Helix QAC improve the security of your C and C++ code. You can use these modules to automatically find security vulnerabilities in your code. And you can create MISRA compliance reports using Helix QAC.
These modules support MISRA C:2012 and MISRA C++:2008 security rules.
How to Apply Secure Coding Standards
The best way to ensure secure coding in C and C++ is to use a .
Static code analyzers enforce coding rules and flag security violations. comes with code security modules — CERT, MISRA, and CWE — to ensure secure software.
Each one includes:
- Fully documented rule enforcement and message interpretation.
- Extensive example code.
- Fully configurable rules processing.
- Compliance reports for security audits.
