App developer? Here are 5 basic code level security practices that you need to consider immediately!

Why does it matter now, more than ever?

With the rising demands on mobile applications, met by the acceleration from the mobile development market, cybercriminals are finding more opportunities to vector data that is becoming abundant. The job of cybersecurity professionals is becoming more complex by the minute, that more rigorous measures need to be taken into consideration to protect the less security-savvy users.

Being installed on a device that has access to device-specific security features like biometric authentication, mobile devices are still vulnerable to security risks like malware infections. The risks don’t stop at the mobile device, since a big percentage of mobile applications are also offered in web-based versions, the vulnerability landscape expands immensely, making their data more accessible through threats like cross-site scripting (XSS), cross-site request forgery (CSRF), and SQL injection attacks. To secure web applications, developers need to adopt secure coding practices, use encryption for sensitive data, and implement measures like server-side validation and access controls.

Mobile devices are still vulnerable to security risks like malware infections.

Code level cybersecurity in application development is a critical aspect of ensuring the security of systems. It involves implementing security measures and best practices at the code level to protect against potential threats such as hacking, data breaches, and malware infections.

Here are some basic, common practices that are widely adopted by developers to ensure the security of their users’ data from the get-go, namely on the code-level:

Input validation

A common-practiced security measure is input validation; Through checking user input’s format, the developer tries to ensure that the user’s does input any malicious code through the online-facing prompts. This can be done using various techniques such as using regular expressions to validate input or using built-in functions in programming languages to sanitize input and reject malicious or unauthorized commands.

These are a just few examples for code level security practices that apply on both mobile and web applications. More practices can be implemented depending on the use case. These can be implemented in your development lifecycle.
