Techniques like MAC address filtering and frame encryption help prevent rogue devices from joining the network or intercepting local traffic. Security at these levels involves validating user input, managing secure sessions, and encrypting data formats.
OSI Model Security Defense In Depth: Layered Protection Strategies
IPsec is a key protocol here, providing encryption and authentication for packets as they route across different networks. Training staff to recognize social engineering attempts also plays a vital role, as the human element often exists above the Application layer.
Web Application Firewalls and secure API gateways are examples of tools that operate primarily within these upper layers to block exploits like injection attacks. At the Physical layer, security involves protecting the actual transmission media, such as cables and radio frequencies, from unauthorized access or tampering.
OSI Model Security Defense In Depth Across All Layers
Network administrators should map their existing infrastructure to the layers to identify gaps in coverage. Understanding the Seven Layers of Security Security is not a single feature but a function that operates at every level of the Open Systems Interconnection model.
