The document outlines the seven layers of the OSI network model and lists security issues associated with each layer. Key issues include theft and denial of service at the physical layer, MAC flooding and data disruption at the data link layer, ICMP flooding at the network layer, SYN flooding at the transport layer, session communication issues, poor input handling at the presentation layer, and vulnerabilities to hacking at the application layer. Overall, it emphasizes the varied nature of security threats impacting different layers of the model.

- 1. 1) Name the seven layers of the OSI network model, and 2) enumerate security issues at each level. I have done the first one for you as an example: Layer 1 - Physical: theft, bit errors, denial of service, noise, signal errors, RF interference, removable media, open wall ports, flooding, natural disasters, EMP bomb. Solution The seven layers of the OSI model are as follows: Layer 1-Physical layer: The security issues at this layer are theft, bit errors, denial of service, noise, signal errors, RF interference, removable media, open wall ports, flooding, natural disasters, EMP bomb. Layer 2-Data link layer: The security issues that can occur at this layer are MAC flooding, disruption in the flow of the data. Layer 3-Network layer: The security issues are: ICMP Flooding, load on firewall, loss of confidentiality. Layer 4-Transport Layer: SYN flood, Smurf Attack, Layer 5-Session layer: The security issues that can occur at this layer can occur during the inter- machine communication. Layer 6-Presentation Layer: The poor handling of input (malicious) can lead to crashes. Layer 7-Application Layer: This layer is most prevalent to attack by hackers. At this layer, the entire application can be manipulated, user data can be stolen. It can lead to destruction of the entire network. This is also known as Denial of Service attack.
