I'm dealing with this issue in a new duty my job has dumped on me. We run several public service answering points (psaps) which need to be secure for various reasons. We have two DSL lines to work with so I put all wired traffic on one using it for sensitive info (911 calls and dispatch info). The second is for wireless connections and is not as secure but I didn't want to make it easy to guess the password. My answer was designed after trolling this forum and learning as much as possible, we employ a foreign character or two in the password (i prefer Thai)
My question is to you experts, is this really helping?
