Attacks on layer two of the OSI model Seven layers of OSI In 1977 a model called Open Systems Interconnection (OSI) was proposed‚ with the aim to establish an interoperability standard for different vendor products. This model defines several layers related to data transfer‚ from the lowest (physical) to the highest (application) layer. They have a strong dependence upon one another and headers are usually added when traversing from a lower layer to a higher one. The seven layers are: Layer 1 -

distributed denial-of-service (DDoS) attack is one in which a multitude of compromised systems attack a single target‚ thereby causing denial of service for users of the targeted system. The flood of incoming messages to the target system essentially forces it to shut down‚ thereby denying service to the system to legitimate users. In a typical DDoS attack‚ the assailant begins by exploiting a vulnerability in one computer system and making it the DDoS master. The attack master‚ also known as the botmaster
