8/12/2023 0 Comments Security shift left![]() Much like software testing, security isn’t typically applied until the final stages of software development. As it turns out, shifting left can also be applied to security and audit teams as well. The shift-left strategy isn’t just for software testing. Shift-Left Security: A Natural Progression This is a strategy that originally emerged back in 2001 is becoming increasingly popular among development teams today. This strategy can save money and time while reducing or even eliminating bugs. Shifting left involves testing earlier in the development process instead of saving it until the very end. In many cases, IT decision makers are increasingly asking technical workers to do more with less.Ĭompanies can significantly reduce the time and cost of software development by “shifting left.” This strategy involves building continuous integration and continuous development (CI/CD) pipelines, and integrating automated software testing throughout all levels of production, from planning to monitoring. This is especially true in the current economic environment, where organizations are faced with tight budgets and, in some cases, reduced technical teams. ![]() Cross-Site Scripting (XSS) Protection: To prevent XSS attacks, you should test that your rendering function properly escapes user input.Software is rising in cost and complexity every year, making it harder for companies to iterate and compete. void testSqlInjectionVulnerability() Other examples for the user interface (JavaScript)ġ. Injection (OWASP A1): Create input validation tests to mitigate injection flaws. We can use unit tests to help prevent these risks from happening.ġ. One way to do this is to follow the OWASP Top Ten 2 security risks while writing and compiling our code. We want to ensure our code is secure and get feedback early. Why not make security-based unit tests a core practice of your team? OWASP Top 10: Key Practices for Secure Development in the coding stage The objective is to identify security issues quickly alongside quality and defects. Here’s the kicker: what if we did the same “shift-left” approach for security? Developers can access helpful tools such as profilers, static analysis, and dynamic analysis scanners. Significant improvements have been made at the platform and systems levels. It’s no longer just about developing features but ensuring they are secure and reliable for our users. Security has become indispensable to our work in the evolving technology and software development landscape. ![]() ![]() Our journey started several years back with Martin Fowler’s article on the practical test pyramid 1 and adopting the practice of test-driven development (TDD). Several libraries support unit test implementation in most languages. ![]() For us, we started shifting left for quality, running tests at all levels, and moving from depending on extensive, long-running tests in staging or production environments to reducing the number of these tests and replacing them with tests earlier in the flow (shifting the tests left). Why should we postpone identifying an issue until the last minute? The cost of detecting an issue increases as it is detected later in the delivery flow (cost is a whole other conversation). It’s about determining if your code modification is functioning as intended and detecting any potential damage to pre-existing code as soon as possible. I define shift left as enabling the earliest feedback. Let’s Shift LeftĪre you familiar with the term “shift left”? It is a popular concept in the tech industry for good reasons. What outcome do we hope to achieve? Additional security coverage, where applicable, earlier in the software development lifecycle. What are we trying to improve? The adoption of practices to find security vulnerabilities early in the development lifecycle. ![]()
