An Intrusion Prevention System (IPS) includes automated security actions, such as blocking malicious traffic, resetting connections, or alerting administrators when it detects suspicious activity, helping to stop attacks in real time.

A Host-Based Intrusion Prevention System (HIPS) is installed directly on an endpoint device (such as a server or workstation) and monitors local system activity, including processes, file access, and system calls, to detect and prevent malicious behavior.

Tunneling is a method of transporting data across a network using protocols that are not supported by that network. Tunneling works by encapsulating packets: wrapping packets inside of other packets. Tunneling within commonly used services is a technique that uses file sharing or an instant messenger client such as Meebo running over HTTP to bypass firewalls or other network restrictions. The data packets are encapsulated within HTTP packets and sent as normal web traffic. This way, the data packets can reach their destination without being blocked or detected by the network. References: What is tunneling? | Tunneling in networking | Cloudflare, What Is Network Tunneling & How Is It Used? | Traefik Labs, networking - What is HTTP tunneling? - Stack Overflow

A botnet is a network of computers or devices that are infected by malware and controlled by a malicious actor, known as the botmaster or bot-herder. The botmaster uses a command and control (C2) server or channel to send instructions to the bots and receive information from them. The C2 communication is essential for the botmaster to maintain control over the botnet and use it for various malicious purposes, such as launching distributed denial-of-service (DDoS) attacks, stealing data, sending spam, or mining cryptocurrency. Therefore, the key to “taking down” a botnet is to prevent the bots from communicating with the C2 server or channel. This can be done by disrupting, blocking, or hijacking the C2 communication, which can render the botnet ineffective, unstable, or inaccessible. For example, security researchers or law enforcement agencies can use techniques such as sinkholing, domain name system (DNS) poisoning, or domain seizure to redirect the bot traffic to a benign server or a dead end, cutting off the connection between the bots and the botmaster. Alternatively, they can use techniques such as reverse engineering, decryption, or impersonation to infiltrate the C2 server or channel and take over the botnet, either to disable it, monitor it, or use it for good purposes. References:
