The OSI model security framework provides a structured approach to understanding how data moves and is protected across a network. At the Physical layer, security involves protecting the actual transmission media, such as cables and radio frequencies, from unauthorized access or tampering.

Regularly updating protocols, patching systems, and conducting vulnerability assessments are non-negotiable practices. This structured method ensures that security evolves alongside the network architecture.
Physical and Data Link Layer Considerations The Physical and Data Link layers form the foundation of the OSI model security structure. Leveraging the Model for Defense in Depth One of the greatest strengths of the OSI model security approach is its alignment with the concept of Defense in Depth.

If one layer is compromised, the others still provide protection and time for detection and response. Security at these levels involves validating user input, managing secure sessions, and encrypting data formats.
