This is a very timely topic from my perspective. We are moving to SSO via a portal and I'm trying to convince my colleagues that if we're going to continue to rely on single factor authentication, we need to move beyond 8 characters with mixed case and special characters. I would like to see us require a 15 character pass phrase which, in my view, is more secure (even without complexity), and both easier to type and remember. This is a tangential topic, but I was wondering if anyone on the list was familiar with brute force tools that would work against web forms. My concern is that without some kind of lock out policy, an account with a 8 character password would be vulnerable to a brute force attack. It's encouraging to see Jonny's reply below on the use of longer pass phrases. Sweeny, Jonny wrote:
Passphrases MUST contain at least: * 15 to 127 characters (at least 4 of which are unique) * 4 or more words (a "word" is defined as 2 or more distinct letters separated by 1 or more spaces or non-letters) Passphrases MUST NOT: * contain the "at" sign (@) * contain the "number" sign (#) * be a common phrase (such as "to be or not to be" or "April showers bring may flowers") * be based on predictable patterns such as the alphabet or the layout of a standard keyboard * contain your name or username No expiration presently. We're working on that. -- ~Jonny Sweeny, GSEC, GCWN, GCIH, SSP-CNSA Incident Response Manager, Lead Security Analyst Office of the VP for Information Technology, Indiana University PGP key & S/MIME cert: https://itso.iu.edu/Jonny_Sweeny jsweeny () iu edu p(812)855-4194 f(812)856-1011 -----Original Message----- From: Brian T Nichols [mailto:bnichols () LSU EDU] Sent: Monday, November 19, 2007 12:49 To: SECURITY () LISTSERV EDUCAUSE EDU Subject: [SECURITY] Passwords & Passphrases Colleagues, We are researching best practices regarding passwords and passphrases (length, complexity, expiration, etc..).
