Answer 1

In which layer does the attack take place? The question might seem noob as each of these layers are vulnerable to different types of attacks and not only just one of them gets you access to a network or a system. I'll explain some major attacks in each of these layers and hope you'll find it useful. I wont be getting into the details of each layer but will be into the attacks.

Transport Layer: Transport layer of the osi model is vulnerable to Session Hijacking. The attacker takes control over the session between two nodes. The authentication of a session usually takes place when the session is being started and once the session has been established the attacker masquerades as one of the session and hijacks the session.

Application Layer: Application layer is vulnerable to Repudiation which is the denial of service.

Network Layer: It usually comes with a list of attacks. Some of the major attacks in this layer is, wormhole attack, blackhole attack, byzantine attack, information disclosure, routing attacks etc.

Besides these there is multilayer attacks which makes use of one or more layers to intrude into a network.
