Using encryption
Posted: Sun Jan 19, 2025 3:39 am
Because VoIP calls are transmitted over the web, they are vulnerable to interception and eavesdropping. The best way to guard against this is to ensure that the traffic is encrypted. There may not be any additional cost here; your existing network equipment may well have an encryption capability just waiting to be turned on.
Most networks have a f canada telegram irewall, but for VoIP, you need to ensure that it is configured correctly to handle the traffic otherwise you could end up introducing more problems for yourself. It’s essential that your system is properly configured to fend off DDoS attacks, which can be used to degrade your VoIP service or even render it impossible to make calls.
Where staff are accessing your VoIP system from outside the office, at home or via mobile devices, you should consider using a VPN. This effectively creates a secure tunnel between the endpoint and your network, making it much harder for the connection to be interfered with.
Training matters
One of the keys to keeping your network secure is to ensure that all of your staff are properly trained. This ensures that everyone is aware of the need to keep networks secure by using secure passwords and not sharing login details. It also serves to raise awareness of threats such as SPIT (SPam over Internet Telephony) and Vishing (voice-based phishing attacks).
Something you should also do is to test your network regularly for vulnerabilities. This will show up any weak points and allow them to be addressed before they can be exploited. You should also carry out regular audits of user accounts and ensure that as people move departments or leave the business, their access privileges are adjusted or revoked accordingly.
