In this era of vulnerability to cyber attack developers DevOps teams need to step up. Here we explore the concept of secure coding and provide several best practices that can help developers level up their skills and adopt secure coding.
What Is Secure Coding?
Secure coding involves practices, techniques, and tools that prevent accidental or malicious introduction of security vulnerabilities into software code. Threat actors often look for defects, logic flaws, and bugs they can exploit in software applications.
Identifying insecure coding practices that lead to these errors, and implementing secure coding practices, can reduce vulnerabilities and eliminate security problems long before software is deployed to production. This can reduce the attack surface, minimize risks, and reduce the impact of a breach even in case of a successful attack.
Secure Coding Statistics
Secure Code Warrior has released the results of its 2022 survey on the state of developer-centric security. The findings suggest that developers have conflicting security attitudes and behaviors. Most developers recognize the importance of a security-centric approach to software development; 86% don’t prioritize application security when coding.
According to the survey, over half of the developers failed to secure their code against the top seven vulnerabilities. Secure Code Warrior conducted this study to evaluate how developers can adopt proactive, secure coding practices.
Developers must address several priorities, with many administrative barriers preventing them from writing secure code early in the SDLC. Developers often prioritize deadlines or lack the guidance and training to write secure code.
Training significantly impacts the development team’s adoption of secure coding practices, with 81% of developers applying the knowledge gained from training in their daily work. Despite implementing the mechanisms from training, 67% of developers knowingly shipped vulnerable code. Many developers expressed a desire for further training.
Secure Coding Best Practices
Here are critical best practices developers must know to ensure their code and the surrounding environment are secure.
Shifting security left enables prioritizing security across the entire software development lifecycle (SDLC). It helps discover and remediate flaws early on, minimizing the probability of personnel ignoring security issues because they are forced to meet unforgiving time schedules.
Implementing security as an integral part of the development process enables teams to assess the risks of dependencies and open source components before including them. It also helps ensure versioning is consistent throughout the project.
Teams can leverage information from sources like the OWASP Top 10 list to get professional guidance on vulnerability management and use tools to make this process faster and more efficient. Here are common shift-left security tools:
Validation of Inputs and Encoding of Outputs
User inputs and encoding outputs can cause severe vulnerabilities. Here are common best practices to help mitigate this threat:
Error Handling and Logging
Error handling processes deal with unexpected outcomes that occur when a program is given unusual input. Error handling problems can expose sensitive information. Teams can mitigate this risk by using logging to maintain a record of changes made to applications.
For example, a threat actor can search for individuals using the same credentials so they could use these credentials to obtain access to many accounts. If there is no logging or tracking of these event occurrences, actors can keep performing these attacks using new credentials.
Here are common errors handling and logging approaches:
