Scapy
Scapy is a powerful Python-based interactive packet manipulation program and library used for network analysis, penetration testing, and security research. It allows developers to craft, send, capture, decode, and analyze network packets at a low level, supporting a wide range of protocols. It is commonly used for tasks like network scanning, packet sniffing, and protocol development.
Developers should learn Scapy when working on network security, penetration testing, or network protocol analysis, as it provides fine-grained control over packet creation and manipulation. It is particularly useful for simulating network attacks, testing firewall rules, and debugging network applications, making it essential for security professionals and network engineers.
