Long before that, VoIP service was a new and innovative concept. Today, Internet-based voice communication is common among SMEs. It is time to focus our attention on improving security. Failure to fully understand what is required to protect a VoIP system can lead to vulnerability to cyber attacks. Let's take a closer look at five key tips for protecting web-based communication devices and services.
Threat type
The vast majority of VoIP services involve live communications and often look much more harmless than stored data. Unfortunately, as much valuable information travels through VoIP managed services networks as it is hosted on corporate servers. Internet-based calls are much more vulnerable to fraud than traditional phone services and face threats such as identity theft, eavesdropping, intentional interruption of service, and even financial loss. I will.
24/7 Monitoring
According to a recent Nettitude survey, 88% of VoIP security breaches occur outside of normal business hours. This could allow an attacker to use your account to make calls or attempt to access call logs that contain confidential information. This can be avoided by outsourcing IT providers to monitor network traffic for anomalies and spikes in suspicious activity.
VoIP Firewall
All VoIP providers must offer firewalls specifically designed for IP-based telephony. These protocols limit the type of traffic allowed, ensure that connections are terminated correctly at the end of a session, and identify suspicious ring patterns. Contact your VoIP or IT service provider to find out which of these features are available and which are currently used by your organization.
Encryption Tool
One of the common reasons for eavesdropping is the lack of encryption. An inexperienced attacker can easily download and implement the tool to intercept and listen to the call. Some services claim built-in encryption, but be sure to research how effective they are in practice. Many of these protocols are much more difficult to control because they require the same VoIP client on the receiving end of the call. Cryptography is compatible with many other software clients and should effectively prevent the privacy of the call from being compromised.
Virtual Private Network
A virtual private network (VPN) creates a secure connection between two points as if they occupy the same closed network. It is like building a tunnel between you and the recipient of the call. In addition to adding another layer of encryption, establishing a VPN also overcomes the complexity associated with the recommended VoIP feature, Session Initiation Protocol Trunking.
Password Protection
Password protection generally refers to requiring password authentication to gain access to confidential information. However, in this case, it really means protecting the password itself. Sneaking around is one of the easiest and most common cyberattacks against VoIP networks, and using all of the above protocols requires you to tell your employees not to leak information during a VoIP call. ..
VoIP is as important as any other network security consideration. I need my own combination of protection measures and would like to provide advice on the implementation of these protections or the administration of VoIP services. Please contact us by phone now.
