I'm the admin for my company and unfortunately, the majority of the company is tech-skills limited. I need to impress upon them the need and reasoning for updating publicly WiFi hot-spots at our locations so that the passwords change weekly.
Does anyone know of any good white papers or articles that discuss the dangers associated with keeping the same password for extended periods of time?
To explain further, the wifi is at restaurants which have been plagued by homeless that "squat" in there without purchase, others using the free wifi to download porn and torrents, and other physical security issues. The wifi is offered free to customers but needs limitations and uses the same modem that the point of sale operates on (in the DMZ though). Security (both physical and virtual) is limited so I update the passwords weekly to help improve our protection. But explaining how leaving a simple WiFi password on an publicly visible and accessible hotspot opens the door to penetration and exposure is difficult to explain to non-security minded persons.
