Custom source code accounts for 93% of app vulnerabilities, according to a recent study. This means that the code written specifically for an application, rather than relying on pre-built components, is more prone to bugs and security issues. But why is this the case?
One reason custom source code is more vulnerable is that it is often not as well-tested as pre-built components. Developers may overlook certain edge cases or fail to properly secure their code, leading to exploitable vulnerabilities. Additionally, the sheer complexity of custom code can make it harder to spot potential issues, especially when dealing with large codebases.
Some common types of vulnerabilities caused by custom source code include SQL injection, cross-site scripting (XSS), and insecure direct object references. These issues can be exploited by malicious actors to gain unauthorized access to sensitive data or compromise the integrity of an app. Understanding these vulnerabilities is crucial for developers to better protect their applications.
There are several steps developers can take to mitigate the risks associated with custom source code. One of the most important practices is regular code reviews by experienced developers to identify and fix potential vulnerabilities. Additionally, integrating automated security testing tools into the development process can help catch issues early on.
Furthermore, following secure coding practices, such as input validation and output encoding, can help prevent common vulnerabilities like SQL injection and XSS. By taking a proactive approach to security, developers can better protect their applications and reduce the likelihood of a breach due to custom source code.
Custom source code accounts for a significant portion of app vulnerabilities, making it essential for developers to be aware of the risks and take steps to mitigate them. By understanding the common types of vulnerabilities and following secure coding practices, developers can enhance the security of their applications and minimize the potential impact of security breaches.
