Layer 1 and 2 DoS Attacks
Denial of service at level 1 or 2 can take two forms.
The first is a physical denial of service - this would be something like radio jamming or snipped network cables. This is a physical means of preventing a sheep from connecting to a network or to other resources.
The second is at the router level, and consists of tampering with the CAM table, which maps MAC addresses to IP addresses. (Note: technically, this is really a level 3 attack, but since I can't think of any purely Level 2 DoS attacks... there you go.)
CAM Overflow/MAC Flood: DoS/Mac Flood
- This type of attack is more useful in man-in-the-middle attacks, as a full CAM table does not break the router, it simply causes the router to broadcast traffic to all ports and all parties on the network.
- It can still be a useful mitigation technique, however. For routers on small networks that are logging MAC addresses of clients, one new mac address may
Denial of Servicedenial of service attacks for denying users access to resources that they are otherwise entitled to access.
