Application security describes security measures at the application level that aim to prevent data or code within the app from being stolen or hijacked. Such security includes built-in security measures, such as an application firewall that strictly defines what activities are allowed and prohibited, as well as an application security routine, including protocols like regular testing. Security threats often occur in areas like authentication, authorization, encryption, auditing and logging.
Application security is important because today’s applications are often available over various networks and connected to the cloud, increasing their vulnerability to security threats and breaches. There’s increasing pressure and incentive to not only ensure security at the network level, but also within applications themselves.
