Network traffic analysis (NTA)¶
Network Traffic Analysis (NTA) is like cyber-ecology with a packet microscope, sifting through the soil of TCP streams and UDP spores, hunting for a glint of malicious payloads camouflaged in plain sight. Is that a golden nugget of exfiltrated data? Or just another false-positive truffle rotting in the SSL undergrowth? Armed with tools like Zeek’s enzymatic log-breakdown and Wireshark’s spectral analysis, it may be possible to spot the fungal blooms of breaches before they poison the whole system.
Warning: Side effects of this work may include muttering `ACK-ACK-ACK` at passing squirrels and developing a Pavlovian craving for coffee every time you see a SYN flood.
