IP Address
An IP address is used to identify any device connected to a network. These devices range from desktops, to servers and even CCTV cameras! We rely on IP addresses to send and receive the information over the network.
Defence:
A common defence tactic is to block, drop, or deny inbound requests from IP addresses on your parameter or external firewall. This tactic is often not bulletproof as it’s trivial for an experienced adversary to recover simply by using a new public IP address.
Fast Flux attack
Fast flux: is a DNS technique used by botnets to hide phishing, web proxying, malware delivery, and malware communication activities behind compromised hosts acting as proxies. The purpose of using the Fast Flux network is to make the communication between malware and its command and control server (C&C) challenging to be discovered by security professionals.
