Word Notes

A network switch configuration setting that forwards a copy of each incoming and outgoing packet to a third switch port. Also known as SPAN or Switched Port Analyzer, RAP or Roving Analysis Port, and TAP or Test Access Point. When network managers and security investigators want to capture packets for analysis, they need some sort of generic TAP or Test Access Point. You can buy specialized equipment for this operation but most modern switches have this capability built in.

NDR tools provide anomaly detection and potential attack prevention by collecting telemetry across the entire intrusion kill chain on transactions across the network, between servers, hosts, and cloud-workloads, and running machine learning algorithms against this compiled and very large data set. NDR is an extension of the EDR, or endpoint detection and response idea that emerged in 2013.

Technology, software and hardware deployed without explicit organizational approval. In the early days of the computer era from the 1980s through the 2000s security and information system practitioners considered shadow IT as completely negative. Those unauthorized systems were nothing more than a hindrance that created more technical debt in organizations that were already swimming in it with the known and authorized systems.

From the intrusion kill chain model, a program that provides command and control services for an attack campaign. While the first ever deployed RAT is unknown, one early example is Back Orifice made famous by the notorious hacktivist group called “The Cult of the Dead Cow,” or cDc, Back Orifice was written by the hacker, Sir Dystic AKA Josh Bookbinder and released to the public at DEFCON in 1998.

A physical security access control device consisting of an enclosed hallway with interlocking doors on each end where both doors can’t be open at the same time. A person presents credentials to the entry doorway. If authorized, the entry door opens and the person walks into the mantrap. The man trap exit door will not open until the entry door closes. The person presents credentials to the exit door. If authorized, the exit door will open. If not, the person is captured in the man trap until security arrives to handle the situation. Physical security leadership installs man traps to separate unrestricted areas from restricted areas, to prevent tailgating by uncleared personnel, and to impede access by unauthorized persons.

1. A wireless access point installed by employees in an office or data center environment as a convenience to connectivity without the consent or the knowledge of the network manager. 2. A wireless access point, sometimes called an Evil Twin, installed by a cyber adversary in or near an office or data center environment designed to bypass security controls, gain access, and/or surveil the network traffic of the victim’s network. Both kinds, the employee installed and the adversary installed rogue access points, increase the attack surface of the organization. The employee installed device, because of its electronic footprint range, might make it easier for hackers and mischief makers outside of the organization’s network to bypass the corporate security controls and gain access without permission. The adversary installed device is designed specifically to bypass the security controls of the target network.

A subset of the internet where communications between two parties or client-server transactions are obscured from search engines and surveillance systems by layers of encryption. The U.S. Navy designed the original Darknet by developing The Onion Router network, or TOR, back in the 1990s. Roger Dingledine and Nick Mathewson deployed the first alpha implementation in 2002 with some initial funding by the Electronic Frontier Foundation (EFF.) The TOR Project became a non-profit in 2006 and is funded by the U.S, Sweden, different NGOs, and individual sponsors.

From the intrusion kill chain model, the delivery of a “lure” to a potential victim by pretending to be some trustworthy person or organization in order to trick the victim into revealing sensitive information. According to Knowbe4, the word “phishing” first appeared in a Usenet newsgroup called AOHell in 1996 and some of the very first phishing attacks used AOL Instant Messenger to deliver fake messages purportedly from AOL employees in the early 2000s. The word is part of l33tspeak that started in the early days of the internet (1980s) as a shorthand to let readers know the author was part of the hacker community. In this case, the letters “ph” replace the letter “f” in the word fishing, as in “I fish, with an ‘f,’ for bass in the lake.” In hacking, “I Phish, with a ‘ph,’ for login credentials from key employees at my target’s organization.
