AIS
Automated Indicator Sharing
Automated Indicator Sharing (AIS) is a system where cybersecurity organizations automatically share information about cyber threats with each other. This real-time exchange of data helps everyone identify and defend against attacks faster and more effectively. It’s like a neighborhood watch program, but for cyber threats.

CBC
Cipher Block Chaining
Cipher Block Chaining (CBC) is a way to encrypt information in chunks. Each chunk is scrambled with the key, and then also linked to the previous chunk with a special operation. This chaining effect makes decryption rely on all the previous blocks, improving security compared to simpler encryption methods.
