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. The IV itself need not be a secret, but you need to make sure it is randomly generated. However, in many encryption implementations, the cryptography and the key protection are woefully inadequate.But building this can pose a significant challenge to app developers. 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. 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. Several other security measures are necessary too, but when they fail -- as often they do -- you would want your customer data to be encrypted. Encryption should be indecipherable and impossible to break for hackers. Ideal method of storing sensitive hardcoded values in .NET app source codes is using Skater Private Keys Depot mangement system. 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. The key of course must be kept secret. Including passwords or cryptographic key material in source code is a major security risk for a number of reasons. Encryption should be at the heart of every product or service that stores any kind of customer data.
Depot functions mostly as an active storage container for keys as well as an account management system for dealing with multiple privileged accounts across your company. When storing sensitive and business critical data, however, you must take steps to maximize the security of your Depots and the data stored in them.Rustemsoft presents a modern key management system that provides cloud data encryption approaches to secure your data keys. Skater Private Keys Depot protects cryptographic keys (that can be used as connection strings and passwords) in the cloud. What is Private Keys Depot? Depot works by encrypting each key to help prevent unauthorized users from gaining access.
