Over the last decade, an immense level of maturity has flown into the Voice over Internet Protocol system. This technology which was earlier just considered as a free service to make internet calls has now integrated into the massive communication systems of almost all the large and global business organizations. VOIP along with the highly feature-enriched PBX systems has evolved from simply being a cost-effective system for the small organizations to a complete replacement of legacy PSTN systems in the large business sector.
Massive Growth of VOIP - The Attention Center
It is a fact that what floods internet immensely becomes quite a threat to hackers. Numerous prominent outbreaks aiming protruding VoIP vendors have recently laid enough emphasis on the requirement for business firms to dig deeper into the current security infrastructure and to take into account its authenticity. As the regularity of occurrence and increasing intensity of the digital communication related threats has increased, the requirement of fresh security analysis has drastically changed.
With the massive release of queries through VOIP, the channel used for transmission is quite susceptible to various internet security vulnerabilities. The most common amongst these risks are the Denial-of-Service attacks, automatic call redirection, eavesdropping of the communication channel and unmonitored calling to various destinations induced through bots.
7 Essential VOIP Security Steps
Security as it is addressed today seems quite abstract. There are certain Government regulations that every registered VOIP provider has to include in the concerned digital communication architecture. As they are framed by the Government, these implementations differ from country to country. Apart from these, there are 9 essential steps for setting up VOIP security to the optimal levels:
Security Essential 1: Choice of the VOIP protocols has to be made appropriately so as to encircle the user needs.
Security Essential 2: It is not always necessary that the implementation of greater number of protocols results in greater level of security. The unusual and weak protocols can also invite vulnerabilities by providing hackers with another option to get through. So, such protocols should be turned off while the strong ones should be properly set up to guard the channel.
Security Essential 3: Every component of the digital communication environment is equally susceptible to an attack. Thus, security should not be focused only on the network channel but also through firewalls and antivirus phone in the computers involved.
Security Essential 4: To ensure safe, quick and effective usage of VOIP and other IP network operations, it is better to keep the two channels separate both logically and physically.
Security Essential 5: When operating through remote access and control, authentication and authorization are the two security essentials for securing the security pillars of integrity and confidentiality of digital interaction channel.
Security Essential 6: VOIP infrastructure should always be equipped with effective tracking system to extract the communication port number through the packets sent and received during signaling of information.
Security Essential 7: NAT protocol should be enabled while making the VOIP channel live. This converts all hidden IPs into one unique IP. This helps in determining the calls from non-traceable or dynamic IPs. This helps in identifying and preventing the possible attacks.
The Question of VOIP Security is Rising- What’s the Status of Observation?
As the awareness of security implementations is increasing at a massive pace, the internet carriers are focusing more on the professional evaluation of the operational implementations and their effectiveness in the comprehensive VOIP setup.
Walking through the details of security implementation is estimated to be a heavy expense inculcating multiple thousands of dollars that are generally clubbed with the deployment costs. Moreover, this is not a one-time affair and needs regular consideration and modifications thereby incurring a great expenditure. This analysis not only includes analysis of the system structure but also its operation and reliability thereby leading to a comprehensive assessment of the complete channel and all its related devices.
The question here is “Are security checks really important? And if they are, then to what level the security should be checked so as to keep the budgets and VOIP functionality in a healthy state?” The answer to this question is not unanimous and depends on the severity of the different enterprises which mainly depends on the purpose for which the communication channel is utilized.
Business organizations that set up their own IP PBX systems are often more vulnerable to security breaches since the IT administrators often fail to recognize the loopholes that may have crept in during the implementation of the channel. In the case of Hosted PBX systems, security checkup is the responsibility of the provider offering the VOIP services. The need of professional experts to check the complete channel of implementation is thus unavoidable. This way, any flaws in the channel, if identified can be easily patched before any internet hacker can discover them.
