ust how safe is VoIP?

[mdabuhasan]

As everyone now knows, VoIP communications are carried across the internet in data packets just like other forms of internet traffic and can, therefore, be exposed to the same kinds of risk – such as hacking, interception, spoofing, counterfeiting or denial of service attacks. Internet attacks are notoriously hard, or even impossible, to trace and therefore very difficult to deter.

When VoIP technologies were only being used by large corporations, communications were often confined within a local intranet or WAN. These were already relatively well protected from outside intrusions. But of course, now that VoIP data is transmitted over the internet at large, it could be vulnerable to the same kinds of risk, and subject to the same data and privacy protection laws as any other form of internet traffic or digital information.

This is a double risk exposure – to the dangers of deliberate abuse or attack and to the risk of being prosecuted under the GDPR, DPA or other legislation if an incident is deemed to have been partially caused by poor precautions on the part of any party involved.

Most VoIP traffic still goes across the cameroon whatsapp number data net unencrypted. Anyone with the appropriate packet-sniffing setup can listen in to those calls. Spying on phone calls is a serious security issue in itself, but the information gleaned from monitoring calls can then be used in other damaging ways. Hackers can potentially assume the identity of a caller and use the information in order to extract confidential personal, financial or business information from a third party. If a thief spoofs your phone numbers to take credit card payments from your customers, who will get the blame?

How business VoIP providers can help
None of the risks to which VoIP exposes a business or network are technically new. VoIP is carried as a form of digital data and therefore suffers the same risks and benefits from the same precautions as previous forms of digital data. Firewalls, anti-viral and anti-malware security suites and network monitoring (for example an IPS system) will all help to make your network safer for VoIP as they already do for emails, applications and browsing. However, there are many businesses that in the past had few reasons to worry about their internet access and traffic – but will now need to review the additional risks.

Responsible business VoIP providers such as IDT encourage their clients to be aware of these dangers and suggest ways to protect themselves. When a provider is pro-active in this way, it also demonstrates to their clients that they are a company that takes security seriously. Many of the precautions are familiar and straightforward; regular firmware and security updates, changing passwords regularly, using VPNs for connection to remote devices, domain restrictions, deleting recorded messages and of course employee training in the new risks.
