- Clustered Firewalls: This is the first step to take to secure the VoIP system you are using. Clustered firewalls are the ones which ensure the security of the system by restraining unauthorized apps to see private information you need to put to use in the system. These firewalls also provide stability to the system along with providing safety.
- Intrusion Avoidance System: This is another step to take to protect the system. IAS prevents intrusion from unknown and unauthorized applications. It also monitors the overall load and the number of sessions. Doing this, it also closes the other connections that go beyond the specified limit and prevents degradation of service. IAS also inspects all incoming and outgoing traffic to keep track of the total load of service so that it can stop service even before gets overloaded. Along with all these functions, there are other certain functions that IAS is capable of. They prevent system penetration and protect client information and customer billing. So, if you are looking to do something about the security measures of the VoIP system you are using, IAS is a great step to take.
- Call Behavior Monitoring Algorithm: Call behavior monitoring is another option to choose for VoIP security measures. This algorithm provides the monitoring of the calls and looks for abnormal routing of calls and any kind of anomaly that is occurring during the call. If those calls seem like improper or deceptive, then this algorithm possesses the capability to stop those routes completely and disconnect the call.
- Encryption System: Encrypting your calls is the best way to secure your VoIP lines. There are many VoIP service providers in the market who use the term “encrypted” as part of their marketing. As long as the calls are encrypted there are less chances of a security breach. There are some encryption methods listed below which are used to secure the VoIP lines. The first one is TLS or Transport Layer Security. It obscures the protocols that you are using making it hard to intercept or detect VoIP calls. The second one is ZRTP which is known as Zimmerman Real-Time Transport Protocol. This protocol is based on a strong cryptographic key arrangement. In order to secure the delivery of data over the Internet, two VoIP devices have to come to agreement on the encryption keys and ZRTP does the job to effect a direct agreement between the caller and receiving ends. The third encryption is known as SRTP or Secure Real-Time Transport Protocol. This encrypts the voice from both ends. Though anyone who is monitoring the servers can detect the voice data, they will not be able to decipher anything.
- Credit Limits: This is another useful way to choose to secure your VoIP. There should be an assignment of credit limits at the service provider’s end. If the service provider notices anything irregular or abnormal use of credits compared to previous data, the service provider can disconnect the connection.
