What type of security is associated with each level of the OSI model?
The OSI reference model for networking (ISO 7498-1) is designed around seven layers arranged in a stack. The OSI security architecture reference model (ISO 7498-2) is also designed around seven layers, reflecting a high level view of the different requirements within network security.
| Layers (ISO 7498-1) | ISO 7498-2 Security Model |
|---|---|
| Application | Authentication |
| Presentation | Access Control |
| Session | Non-Repudiation |
| Transport | Data Integrity |
| Network | Confidentiality |
| Data Link | Assurance / Availability |
| Physical | Notarization / Signature |
Here's a very good paper on OSI model in reference to information security, by SANS Institute.
