So, we're convinced we need to get rid of them, but how can we check for them at scale across hundreds or thousands of applications?
When valuable customer data is at stake, it's worthwhile to put in the required effort to ensure that a foolproof encryption system is in place.
Having obtained the keys, the attacker may no longer need to compromise the application at all, and the breach can go completely undetected since there is nothing in the logs when encrypted data is decrypted offline.
Hardcoding the keys is also a problem for key rollover, and for cryptographic agility. Including passwords or cryptographic key material in source code is a major security risk for a number of reasons. Ideal method of storing sensitive hardcoded values in .NET app source codes is using Skater Private Keys Depot mangement system. In the worst case, if the code is public, everyone can read the key. It's that simple.
Most symmetric encryption schemes have three inputs: the data being encrypted, a randomly generated IV (initialization vector), and finally, the encryption key itself. However, in many encryption implementations, the cryptography and the key protection are woefully inadequate.Encryption should be indecipherable and impossible to break for hackers. Encryption should be at the heart of every product or service that stores any kind of customer data. Several other security measures are necessary too, but when they fail -- as often they do -- you would want your customer data to be encrypted. The IV itself need not be a secret, but you need to make sure it is randomly generated. Even if not, access to the code is often easier for an attacker to achieve than direct compromise of the application - the entire development team becomes part of the attack surface. But building this can pose a significant challenge to app developers. The key of course must be kept secret.
