How to Secure Source Code

Hacking is a real threat in this day and age, and companies have to be especially careful when it comes to protecting their source code. The more innovative your source code, the more worried you’ll be about someone stealing it, and the more reason you’ll have to protect it. So here are some basics of how to secure source code:

  • Use Application Security Testing. Secure code reviews are necessary before releasing an app. In some countries, they’re even mandatory. So you’ll have to check for such things as session management, data validation, and logging before your app gets the green light. Application security testing will check for any bugs or weak points in the source code, and make sure that it’s protected against hackers. Rather than auditing your system manually, you’d be well advised to use a vulnerability scanner, such as those offered by With the help of a scanner, you’ll be protected from SQL injections and other such forms of attack; though you may decide to save money and do it manually, in which case you’ll need to be well-versed in the programming languages used. Manual scanning is especially timely and laborious, which is why automated scans are advisable.
  • Encryption. In the event that a hacker does get through to your database, make sure to encrypt data that might be deemed compromising: passwords, financial information, etc. You can use such services as Javascript encryption to perform this function.
  • Use SCMs. An SCM is a Source Code Manager. This is a tool used by teams to manage their source code. SCMs serve to record any changes made to the software by team members, i.e. any revisions. Major SCMs include Apache Subversion, Git, and Mercurial. The most popular SCM, also known as a Revision Control System, is the Concurrent Versions System. This is a free software that tracks changes and allows developers to collaborate in a single shared server.

Well there you go. Those are just a few of the measures you should take to secure your source code. Besides these, all companies should have a careful vetting process to ensure that no rogue coders get through to their teams, and all code should be copyrighted. I hope that’s been partly useful, and I wish you the best of luck in protecting your source code.
