Dial-in Security
Routinely change modem numbers
Use automatic number identification (ANI)
- Only users dialing in from authorized locations are granted access
- User dials-in and logs into his/her account
- Modem (at server) hangs-up and dials back user’s modem’s prespecified number
- ANI: allows the user to dial in from several prespecified locations
Use one-time only passwords
- For traveling employees who can’t use ANI
