7 Layers

The layer of the OSI model that represents the physical medium that connects computers together, such as cables or fiber optic cables.

Layer 1: Physical

A Layer 1 threat that involves tampering with the physical cables of a victim's network to intercept and listen to network traffic.

Wiretapping

The layer of the OSI model that defines how computers logically connect to the network and includes protocols such as Ethernet and Wi-Fi.

Layer 2: Data Link

A Layer 2 attack that uses radio signals to interfere with a victim's wireless network card, preventing communication with a wireless access point.

Radio jammer attack

The layer of the OSI model that allows computers on different networks to exchange data and includes protocols such as IP and ICMP.

Layer 3: Network

An attack at Layer 3 that sends pings to a large number of IP addresses to detect which computers are online and vulnerable to other attacks.

Ping sweep attack

The layer of the OSI model that ensures data is delivered according to the needs of the application and includes protocols such as TCP and UDP.

Layer 4: Transport

A tool used to scan a computer for open ports, which can be used by attackers to identify services running on a victim's computer.

Port scanner

The layer of the OSI model that allows computers to differentiate between connections within a service on the same host, such as remote procedure call (RPC).

Layer 5: Session

The layer of the OSI model that serves as a translation and security layer between applications, allowing for data encoding and encryption.

Layer 6: Presentation

An attack at Layer 6 that involves an attacker intercepting and impersonating the encryption between a victim and a target, such as a bank's website.

Man-in-the-middle attack

The final layer of the OSI model that defines how users connect with application services through protocols such as HTTP, and is host to various attacks.

Layer 7: Application

a tool used by security professionals to detect problems and known bad code that result in vulnerabilities in your applications. It can help you identify weaknesses that could lead to SQL injection attacks, buffer overrun attacks, and a variety of others that may allow an attacker to take control of your server.
