1. There is a Linux-based security bundle of tools called the Security Onion.
2. Zeek, originally named Bro, offers network analysis, while netsniff-ng specifically analyzes Linux networks for shortcomings.
3. DNS Exfiltration is the art of making sinister DNS requests.
4. Suricata is an intrusion detection system or IDS. It's logo has a meerkat standing up on its hindlegs to have a looksee. I think it is also an IPS (intrusion prevention system) offering controls and not just monitoring.
5. The big four Vs or big data are volume (how much?), velocity (how do we stream stuff in?), variety (what are your sources?), and veracity (dealing with uncertainty and the complexity of sanity checks).
