And I wish the entry that mentions me -- "Cryptography: The science of applying a complex set of mathematical algorithms to sensitive data with the aim of making Bruce Schneier exceedingly rich" -- were more true. In any case, I'll bet the assembled here can come up with funnier infosec dictionary definitions. Post them as comments here, and -- if there are enough good ones -- I'll collect them up on a single page.

Also, the only port open on the firewall to access machines remotely. Wired equivelent protection: A tool for deluding yourself into thinking that assumptions that once held still do. OR Wired equivelent protection: CAT-5 cabling. Users: See security holes. Security holes: The ability to do anything useful with a system. Remote access: The ability to use a system from elsewhere. Also, the ability to abuse a system from elsewhere. Security consultant: The person outside your orginization that you pay to secure everything you don't want anybody outside your orginization to know about. Evidence: That which you use to convict people of offenses against you. Also, that which other people use to convict you of offenses against them. Breaking and entering: Research. Dumpster diving: Because one man's trash is another man's instruction manual. Social Engeneering: Getting people paid to be helpful to be a little too helpful. Belt sander: The only way to securely delete the contents of a hard drive. Wire clippers: The most effective tool for securing a computer. Ari Heikkinen • August 13, 2005 2:58 PM I looked at the page and atleast some of it is actually funny, like this: Analyst, security jammit • August 13, 2005 3:10 PM Username/password: A string of characters used to keep honest people out of a system. Pat • August 13, 2005 3:50 PM This is a classic I heard years ago: Encryption: A powerful algorithmic encoding technique employed in the creation of computer manuals. Wim • August 13, 2005 4:09 PM Computer Manual Security policies Sierran • August 13, 2005 4:10 PM Logging: storage array stress-testing Password Policy: Reverse Turing test - means to prove that users are human and hence cannot remember simple, four-class passwords Road Warrior: Virus prospector and cracker attractor VPN: Virtual Private Network, something which is none of those three Penetration testing: BitTorrent Red Teaming: post-layoff beer session Port scanning: ritualized warning used by Actual Dangerous Crackers (See: consultant, penetration testing) Crafted Packet: handwritten layoff notice Malicious Code: financial application Single Point of Failure: See 'CEO' Honeynet: see BitTorrent Wim • August 13, 2005 4:20 PM Complicated Password Any password not belonging to the set: 11111 , 1234567, qwerty, (name of familymember, dog etc) Backup Courier Services Arik • August 13, 2005 4:21 PM Cleaning crew: The lowest paid employees or contractors in your company, with access to most of your company's physical and virtual assets.

Beyond Fear: ....but not beyond hystaria. CEO: The guy with least technical knowledge who makes the biggest technical decisions. Tim Howland • August 13, 2005 8:03 PM Operating Systems: an aspiration rarely achieved; wishful thinking Luke Burton • August 13, 2005 8:40 PM Information Security Policy: a document designed to cover the arse of the Information Security people should any security problem arise. Full compliance with this document would require users to burn their PCs, crush them into cubes, and bury them deep within the earth. The document is inevitably written by someone so anti-social that they would never be hired on the business side, but so untalented that they have no practical use in the IT department. Luke Burton • August 13, 2005 8:52 PM Unix Systems Administrators: these come in two flavours. 1. The young, thoughtful type who will go out of his or her way to help you solve a problem, as long as you phrase the question correctly. Reads slashdot, cryptogram, phrack, and generally ignores company policy when it's expedient to do so. Wears a lot of black and has at least one open source related toy on desk. 2. The thoughtless type who adhere to company policy like superglue and prevent any real work from being done. Typically saw their first Unix prompt in University and keep a small cheat sheet of commonly used commands on their desk. Are generally to be avoided because in the unlikely event you actually have them perform a task for you, they will certainly stuff it up. Wears neat casual clothes and has an unusually tidy desk. Luke Burton • August 13, 2005 8:59 PM Patching: the act of installing software, provided by a vendor, to address a security hole or bug. Typically done after malware has already exploited the hole and the vendor is receiving negative publicity because of it. If the act of patching does not fundamentally destroy the machine, you may also expect it to introduce new and improved security holes. Luke Burton • August 13, 2005 9:04 PM Information security consultant: a parasite who derives an income stream from the paranoia of others. Sometimes the parasitic relationship is mutually beneficial; frequently though the host finds themselves robbed of a large amount of cash for no measurable gain in security. Apart from sizeable holes appearing in the host's bank balance, the presence of a security consultant might also be detected by their droppings, called "information security policy documents" (see above). Luke Burton • August 13, 2005 9:10 PM Single sign on: a delirious utopian fantasy wherein users can authenticate themselves on all company systems using the same authentication token. In the wildest fantasies this might include a convenient physical token like a smart card. No known implementations of Single Sign On have been seen in the wild. Sometimes very smart people end up in mental asylums after attempting an implementation; approach a project like this at your own risk. Luke Burton • August 13, 2005 9:15 PM Wireless security: 1. an oxymoron. 2. Something that exists in a parallel universe where there are no malicious eavesdroppers and everyone loves one another. Terry Browning • August 13, 2005 9:44 PM Trusted person Trusted system or device Trusted computer Trustworthy person Security system Dumpster Email Virus 0wn493 Nathan Sharfi • August 13, 2005 11:14 PM This may seem like nitpicking, but it seems like they'd all be (slightly) funnier if they ended with periods. If nothing else, that's the style of Bierce's witticisms when they pop out through fortune(6)... Stu Savory • August 14, 2005 12:08 AM Keyword : an easy to remember short distionary word, so that don't have to write it down.

Gunnar Peterson • August 14, 2005 11:33 AM "Cryptography is nothing more than a mathematical. framework for discussing the another_bruce • August 14, 2005 1:23 PM encryption David Harmon • August 14, 2005 2:36 PM Folks, the titular reference is to Ambrose Bierce's work, _The Devil's Dictionary_: http://www.alcyone.com/max/lit/devils/ Some of you may want to check that out, just to pick up the proper attitude and form for these things. Another example: Intellectual Property: The legal basis for preventing anyone poorer than you from profiting by the ideas you stole from them.
