Final answer:
Layer 5 to 7 threats commonly include eavesdropping and worms, with eavesdropping threatening the Session Layer and worms targeting the Application Layer. However, the 'Ping of death' targets the Network Layer, while 'SYN floods' are associated with the Transport Layer, indicating a mix of threats at different OSI model layers.
Step-by-step explanation:
When discussing security threats in the context of the OSI model, it's important to understand which layers are targeted by different types of attacks. Layer 5 (Session Layer), Layer 6 (Presentation Layer), and Layer 7 (Application Layer) of the OSI model deal with the control of sessions, data representation, and application services respectively. Here are some common threats that pertain to these layers:
- Eavesdropping - This type of attack pertains to unauthorized interception of private communications. It is a threat common to Layer 5, where session hijacking might occur, allowing attackers to steal session tokens and gain unauthorized access.
- Worms - Worms are a type of malware that replicate themselves to spread to other computers. This threat typically affects Layer 7, where applications can execute malicious code.
In contrast, 'Ping of death' and 'SYN floods' attacks are more commonly associated with Layer 3 (Network Layer) and Layer 4 (Transport Layer), respectively. These layers deal with routing and data transport, making them the target of such attacks.
