Descripciones CAPEC
An adversary uses full TCP connection attempts to determine if a port is open on the target system. The scanning process involves completing a 'three-way handshake' with a remote port, and reports the port as closed if the full handshake cannot be established. An advantage of TCP connect scanning is that it works against any TCP/IP stack.
Informaciones CAPEC
Flujo de ejecución
1) Experiment
An adversary attempts to initialize a TCP connection with with the target port.
2) Experiment
An adversary uses the result of their TCP connection to determine the state of the target port. A successful connection indicates a port is open with a service listening on it while a failed connection indicates the port is not open.
Prerrequisitos
The adversary requires logical access to the target network. The TCP connect Scan requires the ability to connect to an available port and complete a 'three-way-handshake' This scanning technique does not require any special privileges in order to perform. This type of scan works against all TCP/IP stack implementations.Recursos requeridos
The adversary can leverage a network mapper or scanner, or perform this attack via routine socket programming in a scripting language. Packet injection tools are also useful for this purpose. Depending upon the method used it may be necessary to sniff the network to see the response.Mitigaciones
Employ a robust network defense posture that includes an IDS/IPS system.Debilidades relacionadas
