Description: Application layer security refers to the measures taken to secure applications at the application layer of the OSI model. This layer is closest to the end user and manages interactions between software and hardware. Security at this layer is crucial, as applications are often the primary target of cyber attacks. Security measures include the implementation of encryption protocols, user authentication, input validation, and protection against attacks such as SQL injection and cross-site scripting (XSS). Application layer security aims to ensure the confidentiality, integrity, and availability of data processed by applications, as well as to protect the user experience. In an increasingly digitized environment, where applications are fundamental to various business operations, security at this layer has become essential to prevent security breaches and protect sensitive user information.
