When it comes to communication over long distances, there is no such thing as a system that is hacker-proof. Almost every form is at some risk of being hacked into or compromised. However, because more and more people are turning to VoIP systems, it has become much easier to install specific security features that can improve the experience. So is a VoIP actually more secure than a landline phone?
Are Landlines More Secure Than VoIPs?
Landlines alone are considered to be the most secure form of communication, although no one really uses them anymore. There is the ability to wiretap a landline, but the same thing can be performed on a VoIP line too. Hackers are also less likely to eavesdrop on a landline because there’s not as much information to acquire.
With a VoIP system or sip trunk, however, there is a lot more security features that are being developed and installed to combat hackers. The main reason is that once a VoIP line is hacked, there is a lot more information that a hacker could obtain.
Why Are VoIPs Easier To Hack?
Landline phones connect to each other through circuit switching. The sound from one phone is transmitted to the other once a circuit is created. Then, once the call has ended, there is no longer the transmission of any data.
With a VoIP, information is being transmitted over broadband Internet. The information is broken down into packets and bundles, transmitted to the other side, and then reassembled like the pieces of a jigsaw puzzle. The moment that any of these packets are intercepted by hackers, then the information is lost.
Are Any VoIPs Secure?
There are some systems that are closed in nature that only connect one party to another with end-to-end encryption. However some of these systems can still be hacked in order to intercept the data before it has been encrypted. Even with this knowledge, however, it is not impossible to make secure calls with VoIP.
It isn’t difficult to have a system that uses as much encryption as possible to keep information safe, especially if sensitive information is being shared between end-to-end users. Passwords should be strong and not shared with other people, and shouldn’t be a common word that would make it easy for people to guess.
Testing The Network
The network should be tested on a regular basis to ensure that there are no holes in the security and, if there are, that they are repaired as quickly as possible. Penetration testing serves the purpose of seeing how vulnerable the network really is.
Enabling Network Address Translation
Also called NAT, it is a feature on routers that provides a private IP address to phones, computers, and other Internet devices. By having a private IP, the network cannot be identified by a hacker and it cannot then be manipulated.
Despite the fact that there’s no such thing as an absolutely perfect VoIP system, that doesn’t mean that there aren’t security measures in place to make it as difficult as possible for hackers to get in. If you’re interested in having a VoIP system working for you, then contact your nearest provider immediately.
