A small coding error can give hackers access to a system and expose it to serious security risks in the complex realm of software development. At Protecxo, we stress how crucial it is to use safe coding techniques to protect your applications from these vulnerabilities. This blog seeks to provide insight into common coding errors that compromise security, enabling you to create more robust, secure apps.

Injection Flaws
One of the most prevalent security risks arises from injection flaws, where untrusted data is sent to an interpreter as part of a command or query. SQL injections and Cross-Site Scripting (XSS) are prime examples, allowing attackers to manipulate databases or execute malicious scripts in a user’s browser. To mitigate these risks, employing input validation and parameterized queries is crucial, ensuring that user input is checked and sanitized before processing.

Unsecured Direct Object References
Directly referencing objects using user-supplied data can lead to unauthorized access and manipulation of system resources. For example, altering a user ID in a URL could expose another user’s personal information. Defending against this requires implementing rigorous authorization checks and validating user inputs to prevent manipulation.

Broken Authentication
Compromised authentication processes can lead to unauthorized system access. Issues such as weak password policies or improper session management pave the way for attackers to hijack user sessions or assume false identities. Strengthening password policies and ensuring secure session management, including the use of secure session tokens and implementing multi-factor authentication (MFA), are essential steps toward mitigating these vulnerabilities.

Security Misconfiguration
Failing to correctly configure security settings is akin to leaving your digital doors unlocked. Common mistakes include using default passwords and disabling essential security features. To avoid such pitfalls, it’s imperative to adhere to security best practices and conduct regular security audits to identify and rectify misconfigurations promptly.

Cross-Site Request Forgery (CSRF)
CSRF attacks exploit the trust a site has in a user’s browser, tricking the browser into executing unwanted actions on a trusted site. Protecting against CSRF involves implementing unique CSRF tokens for each user session and validating these tokens with every request, ensuring actions are genuinely initiated by the user.
