Explanation

Atomic-signature-based analysis is a type of attack signature analysis technique that uses a single characteristic or attribute of a packet header to identify malicious traffic. Atomic signatures are simple and fast to match, but they can also generate false positives or miss some attacks. Some examples of atomic signatures are source and destination IP addresses, port numbers, protocol types, and TCP flags. Atomic-signature-based analysis is the technique performed by Joseph in the above scenario, as he analyzed packet headers to check whether any indications of source and destination IP addresses and port numbers are being changed during transmission.
