Every application becomes vulnerable as soon as it's open to the internet, but luckily there are many ways you can protect your application and it's security when your app is being developed.
Application security should be an essential part of developing any application in order to prevent your company and its users' sensitive information from getting into the wrong hands.
Running an application security audit regularly allows you to protect your app from any potential threats and be prepared with a backup if anything were to happen. It's unrealistic to expect to be able to avoid every possible problem that may come up, but there are definitely many known recurrent threats that are avoidable when taking the right measures and auditing your application regularly.
This is exactly why we at Process Street have created this application security audit checklist. It outlines all of the common tasks and checks needed to tighten up your team's application security and can easily be repeated whenever you might need.
