Application Security is the process of ensuring the safety and security of applications via finding, fixing, and enhancing security vulnerabilities. Not all vulnerabilities can be found during the development and therefore fixing the code after the finalization of the project is an important step. Encryption helps cover the data so that even if the breach happens information is unusable to the third party since they do not have access to the private key used to decrypt the data. The service that the application provides is useless if it becomes unavailable for the users.
