 There are multiple layers of information security, including the network layer, application layer, endpoint security layer, and more: 

Network layer

Manages and protects communication between devices and applications on a network. It uses security measures to prevent attackers from tampering with or intercepting information. 

Application layer

Secures applications and services through access controls, authentication mechanisms, and secure coding practices. 

Endpoint security layer

Protects the endpoints of user devices, such as laptops, desktops, and mobile devices. Endpoint security systems can protect in the cloud or on a network. 

Data link layer

Detects and corrects errors in data to ensure reliable transmission between network devices. It also manages sequential and consistent data exchange, flow control, and error control. 

Physical layer

Secures the physical infrastructure, such as data centers and servers, by implementing measures to control access. This includes perimeter security, biometric access controls, and video surveillance. 

Presentation layer

Specifies the encoding, encryption, and compression methods for two devices to communicate properly. 

Human layer

Acknowledges the role that people play in an organization's overall security. This includes employees, contractors, and users.
