Today’s digital world has changed a great deal, opening the doors for new opportunities but also heightened risks, especially concerning data theft. With cyber threats lurking around the corner, it’s critical to fortify your code against cyber attacks. This article presents 8 practical tips to build your walls much higher. By following these tips below, you not only protect your code but also create a safe digital environment for your users.

Choose the Right Programming Language

Your first step towards defending your code against data theft starts with choosing the right programming language. There’s a variety of programming languages that you can use to code. While it’s important to choose one that suits your skill level and your project’s needs, choosing one based on its limitations and vulnerabilities can help too. 

For example, programming in C can expose you to buffer errors. Choosing Java, a popular programming language, also renders code vulnerable to information leaks and deserialization issues. The point is that you have to weigh the pros and cons of each programming language before you commit to using it for your project. 

Use a Code Editor 

A code editor is used by programmers to assist them in writing and manipulating code. It’s worth noting that its use isn’t just limited to just that. In fact, it also helps in bolstering the security of your code. Editors have various features that help programmers get the job done. 

For example, some editors have plug-ins that scan your code for vulnerabilities in real time. Other features like syntax highlighting and error detection spot errors that could otherwise lead to security vulnerabilities. Even the auto-completion feature reduces the amount of typos in code, ensuring robust code. In popular tools like Git, you can track code changes, which streamlines collaboration while maintaining the integrity and security of code. 

Take Note of the Least Privilege Principle 

When it comes to protecting your code, keep in mind the least privilege principle. In simpler terms, this concept limits user access rights to only what is essential. By doing this, you limit the potential damage from accidents or even deliberate actions that might lead to source code exfiltration. Ensure that you adjust the access levels periodically, as needed, to ensure that they remain appropriate. 

Regular Updates

It’s common advice, but it’s often advised for good reason. Don’t forget to update your software, libraries, and systems. As hackers are getting smarter and finding new ways to exploit vulnerabilities in code, it helps to update your software on the regular. New versions of software patch security flaws. If your version is outdated, your code is more vulnerable to data theft. 

Data Encryption

Protecting your data, both in transit and at rest, will involve data encryption. Start with your network controls and ensure that they’re robust enough. Solutions like setting up firewalls will help secure networks against cyber threats. 

Alternatively, using protected tunnels such as HTTPS or SSL/TLS is also an excellent option. For data at rest in particular, you can use an algorithm that converts your data into cipher text, only allowing it to be decrypted with a key. 

Security Training 

If you’re looking to elevate your code’s security, you can’t forget about your first line of defense against data theft: employees. All your efforts will prove futile if your team does not have a full understanding of basic cybersecurity practices. 

Security training involves a broad scope and a continuous effort. Hence, it’s not a one-time task due to the ever-changing nature of our digital world. Discuss topics about phishing awareness, password policies, safe browsing practices, and incident reports. If you cultivate a culture of security in your team, it builds another barrier for your organization to stay protected from cyber attacks. 

Regular Code Reviews

No code is perfect. Even the most experienced developers commit simple errors, overlook best practices, and miss potential vulnerabilities. Regular code reviews serve as an important checkpoint to ensure that your code is functional and secure. 

Assign designated reviewers to scrutinize code. Usually, you’ll have to go with someone more experienced or with a niche skill set. Once a developer submits their code for review, they have to be receptive to feedback. In succeeding projects, they can then learn from this and iterate upon the standard practices to continuously improve code quality. 

Keep Data Backups 

Always have a backup plan. That statement applies to all aspects of our lives and protecting digital data is no exception. Backups are a reliable way to restore information in the event that a data breach occurs.

You’ll first have to identify the critical data and choose appropriate backup solutions, whether on-site, off-site, or cloud-based. Don’t forget to configure your backup tool and customize it according to your needs. That includes the frequency of your backups, for instance. 

Final Thoughts 

The journey to protecting your code from data theft is indeed lengthy, requiring the adoption of a comprehensive strategy. Choosing the right programming language, conducting regular code reviews, and keeping data backups are just some of the many approaches to building strong defenses against data theft. As we traverse through the complexities of today’s digital world, every precaution we take provides assurance that our code, and the data that it interacts with, is in good hands.
