Attacks on VoIP and Unified Communications are increasing with work at home

Companies utilize unified communications (UC) on-prem and cloud to link remote workers, but frequently do not understand the security dangers that hide in popular UC services but should and should address them.

As the COVID 19 pandemic caused firms to switch to work from home (WFH) models, e-Meeting, Voice over Internet Protocol (VoIP), and other UC capabilities have increased significantly. Do not anticipate that tendency to decline at any moment when 93% of CXOs in a ZK Research Study claim they are seeing a permanent 30% increase in the number of distant employees.

Survey respondents stated that the preservation of productivity is the major issue in moving users to WFH and emphasizing the necessity of working tools. The proper ones can seamlessly make the shift. For example, VoIP allows employees to keep the same telephone number at home as at home. They also can link on a computer with a desk, mobile phone, or customer, making the shift almost uncompromising.

Threats are now on SIP

The utilization of real-time communications, however, creates certain safety hazards. Most communication and collaboration applications rely on the data transmission Session Initiation Protocol (SIP). SIP standardization has provided a more productive and interoperable environment for all UC systems. But one of the less recognized features of SIP is that it is vulnerable to infringements, robocalls, and other anomalies.

The number of carriers and corporate networks attacking VoIP and SIP grows fast. Botnet robocalls originate on legal servers or rented servers to conduct hazardous SIP infrastructure assaults globally.

Every day, according to research from RedShift networks, carriers and their company clients are faced with around 40 000 distinct VoIP/SIP assaults. Networks are subject to cyber samples, registration hijacking, and distributed denial of service (DDoS) assaults as well as robocalls.

The 40,000 estimates appear cautious, particularly today with the exponential increase of domestic employees, in my discussions with network and security specialists. The increase of individuals who use VoIP services has given threats and an increase in the number of criminal users focusing on UC systems a significant potential. This is a problem that companies and service providers have long disregarded, but must be taken into account.

New guidelines for combating UC risks have been established

The FCC and foreign authorities are dealing with the problem by forcing the companies to implement the standards for SHAKEN (Secure Management of Asserted Information using KENs) and STIR (Secure Telephony Identity Revisited). SHAKE/STIR aims for the delivery of automatic messages over VoIP and UC systems hacked. Thus, calls over interconnected telephone networks have their caller ID confirmed before they reach end customers.

But not all fake SIP calls can be identified simply. SIP transports not just voice, but all types of media. SIP is used for several applications, such as chat and video conferencing. So it is not enough merely to list IP-based communications or ban them. Busily as businesses update their data networks to meet the rising problem of cybersecurity, they have to focus on safeguarding their VoIP systems.

Protection of communications needs a multifarious approach to security

SIP security, threat intelligence, operational analytics, and automated fraud detection can increase visibility throughout VOIP networks and UC apps in illegal activity. SIP security must be identified and prevented at the edge – or entrance point – of the network, whereas threat intelligence and analytics provide quick troubleshooting and mitigation of threats. In order to monitor the risks within the network in real-time, fraud detection and eventually remediation are necessary.

Select UC threat management solutions for VoIP cyber safety and SHAKEN/STIR standards are particularly created. They use protocols like SIP, Real-Time Transport Protocol (real-time transport protocol, RTP), Transportation Layer Safety (TLS), and Secure Real-Time Transport Protocol (SRTP). Carriers with business clients have used such solutions in addressing important issue areas such as robbery of UC services, expensive DDoS or TDoS assaults, robocalls, and VoIP troubleshooting.

Highly regulated businesses also use UC threat management to preserve compliance through the establishment of a SIP/VoIP protocol basis for routine operations. Unique algorithms with UC threat management are used to authenticate legitimate users and prohibit unregistered users’ abnormal VoIP / SIP conversations or efforts. Health care and financial services are two examples of sectors in which all communications require compliance-level protection.

At the start of this year, FCC ordered all providers, including VoIP providers, to adopt STIR/SHAKEN in their network IP sections by 30 June 2021. Providers are still investing in SIP security because more companies are moving to the cloud to take UC.

Carrier and business networks assaults using VoIP/SIP are not gone. The priority should be to strengthen VoIP security. Without UC safety analytics and monitoring of threats in real-time, companies might be at risk and not fulfill the conformity standards of the industry.
