Command and Control (C2) Server
A Command and Control (C2) server is a computer or a group of computers that sends out instructions to other computers or devices. These instructions could be to execute certain tasks or to steal information. The computers or devices that receive these instructions are called “bots” or “zombies” because they are essentially being controlled by the C2 server.
This type of system is often used in cyber attacks such as Distributed Denial of Service (DDoS) attacks or malware infections. The C2 server is the central point of control that sends out commands to each bot, telling it what to do. This allows the attacker to control a large number of devices all at once, which can be used for various malicious purposes.
In order to prevent these types of attacks, security companies and organizations monitor network traffic for any suspicious activity that could indicate the presence of a C2 server. Once identified, they work to shut down the server and stop the flow of commands.
Overall, a Command and Control server is an important concept to understand in cybersecurity as it plays a crucial role in many types of cyber attacks.
