Keep hackers from eavesdropping on VoIP calls | IT Security | TechRepublic.comQuote:
There are a number of steps that companies can take to protect themselves against VoIP hackers:
* Keep the VoIP network separate from the data network. Although this does negate some advantages of VoIP — such as simplified administration through convergence — it also provides a smaller attack surface and exposes the VoIP network to fewer threats. You can use virtual LAN (VLAN) technology to create a logical separation if you don’t want to go with a full-fledged physical separation.
* Use authentication to ensure that those connecting to the VoIP network from the outside are really who they purport to be.
* Use encryption so that if hackers manage to capture VoIP packets, they won’t be able to easily decipher them.
* Use VoIP-aware firewalls and an intrusion detection system/intrusion prevention system (IDS/IPS).
