  • The Unified Communications-as-a-Service (UCaaS) is now a mainstream technology however; there still remain a few concerns related to the security of UCaaS. One thing to come clear with here is that security shouldn’t be the reason to avoid UC’s transition to the cloud. The ever-increasing mobile communication, remote working, seamless market, and demographic factors ask for the type of collaboration and communication experiences that can be delivered only by the UC.

    PCI compliant cloud hosting enables organizations to deploy communication applications in a quick and consistent manner followed by ease of regular scaling and upgrading! It also caters to security around the applications only if organizations can truly understand the kind of security they’re getting against the service.

    Security is everyone’s concern

    Enterprises mostly make false assumptions of the security being bundled into the usual service package. Even when the service provider mentions it in writing, the security needs for UC needs mutual collaboration as leaving things to intermediary party puts too much at stake.

    And since UC applications are in the cloud, the network, connection points, media, and call flows can’t be protected solely by the cloud unless collaborated with UCaaS provider thereby creating a plan as to who’ll protect what.

    The plan should clarify the protection endpoints and secure connection between the cloud and enterprise network.

    Be realistic of the communications today

    Transitioning the UC to cloud won’t exclude the enterprise network from the equation, however; the move beyond the perimeter does make it more porous with a slight increase in attack vectors. Video and voice calls would still pass from the cloud via a network. Remote workers here aren’t included in the network when you make a call using UC service but, the signal and media flow are likely to navigate through the network at the same time. Even if the UCaaS provider has successfully encrypted the media and signals, issues may still come across.

    Most of the enterprise networks cater to the security of incoming and outgoing data communication in real-time such as UC but different from the data applications due to the use of IP-based Session Infiltration Protocol (SIP). An unsafe SIP raises enterprise risk by introducing Denial of Service (DoS), Telephony Denial of Service (TDoS), and data exfiltration. Still, the extent of security and protection isn’t adequate to completely safeguard the SIP-based applications requiring you to inactivate the firewall functions so that the voice and video work properly.

    When transmitting a video or voice call through a standard data firewall, it’s done by turning OFF the Application Layer Gateway of the firewall’s SIP. Doing so, however; creates loop insecurity that makes it easy for cybercriminals to execute DDoS attacks and data stealing. In case of enterprises truly wish to secure cloud communication, a Session Border Controller (SBC) has to be included in the network which serves as a SIP firewall offering protection and real-time communication encryption on voice and video. It also caters to valuable services including Quality of Service (QoS) assurance, signaling interworking, and media transcoding.

    The intelligent security of the future

    We’re living in a world where more or less a million new malware are released almost every day which literally renders previous protection methods obsolete. This is the reason transition to the latest security analytics and release is critical for better protection and effective countermeasures against the newer threats. The security information however requires sharing throughout the organization and with cloud service partners for being effective completely.

    Solutions for enterprises

    All in all, the three things enterprises can actually do right now for securing their cloud UC services are:

    • Work up a joint security plan with the UCaaS provider ensuring that each party agrees to the responsibilities.
    • Secure the connection points to date with the latest security patches.
    • Add an SBC to every site that would link to the cloud which secures the SIP call flows while ensuring high-quality delivery of voice and video to all.
