This has benefitted organizations worldwide, in terms of ease of operations, higher level of flexibility and better speed to market. However, at the same time, one must acknowledge that management of such a highly complex ICT environment has become a major challenge for many organizations in the digital era.

Organizations must understand that all the components of their diverse IT and network infrastructure – consisting of applications, servers, machines, network peripheral equipment, sensors, or even distinct Cloud environments – are not discrete or isolated units anymore, but a part of a larger organization context, making them extremely valuable for business progression and business continuity. All these components must be unified and viewed in a consolidated way for better performance and security. That’s where, Network Consolidation becomes imperative!

Organizations that have complex ICT environments face distinct challenges that hamper their overall performance and efficiency. Some of the most common challenges in this changing and ever evolving Network and IT environment are:

• Multiple service providers management: Modern enterprises leverage a perfect blend of best-of-breed network solutions from distinct service providers as this ensures advantages of redundancy, resiliency, choice of network media, and connectivity to remote locations. However, managing all the distinct service providers is quite a challenging task and has some inherent problems, such as lack of ownership and visibility, inconsistency in services, inability to leverage analytics, and governance related risks.
• Limited in-house network management capabilities: This is another major concern for organizations across industry verticals. If they opt for establishing an in-house network management setup, then it becomes a very cost-intensive decision to hire the skilled workforce, procure the technology, develop the competence, and achieve a high level of scalability. Furthermore, an in-house setup would need hefty and timely investments to keep pace with evolving technology landscape.
• The demand for constantly re-architecting network: Every enterprise network nowadays has a host of different applications, which has given rise to changed traffic patterns. These mission-critical applications demand uninterrupted collaboration and traffic exchange, which calls for a continuous re-architecting of network to connect data, applications, people, and varied components of the IT infrastructure.
• Shift of focus from Network uptime to Application performance: Traditionally, network has always been uptime-focused, however in current situation where applications are hosted in multiple of Data Centers, Public & Pvt Clouds, businesses are more concerned about how applications perform over the network as this directly impacts the end user experience. The changing demands of high-performance computing and fast cloud migrations have led to a change in paradigm for networks with their SLAs being evaluated on Application intent rather than Network intent. Therefore, new-age networks must capably meet the rising needs of all mission-critical applications that are running concurrently.
• Unification of underlay and overlay networks: To meet changing demands of businesses, networks have grown and evolved organically over different periods of time. This has resulted in complex architectures of underlay & overlay networks. With changing priorities of organizations and rise of application-focused networks, it is important to unify the underlay and overlay networks for optimal utilization, enhanced efficiency, improved user experience, and robust security.
• Connectivity across DC and Cloud landscape: With increased Cloud adoption, it is very important to maintain a perfect sync between data centers and Cloud. Therefore, they need an excellent Network Interconnection that can guarantee seamless connectivity across all the data centers, Cloud environments, international cable landing stations, third party telco infrastructure, etc. for deterministic connectivity and extensive reach.
• Integration of IT, OT, and People: Majority of organizations nowadays have geographically distributed offices, where employees and end users use multiple devices in different regions. It is important to allow them secure and fast access to applications in Cloud and data centers for better experience, collaboration, and organizational efficiency. At the same time, the same Network must ensure seamless connectivity of IT Infrastructure as well as OT assets like WiFi access points, IoT devices and sensors. Herein, network plays an important role in integration of all aspects of IT, OT, and people.

As discussed above, organizations with complex ICT environments face distinct challenges. This not only hampers efficiency and performance but also impacts end user experience, hence compelling organizations to revisit their network strategies. Enterprises want actionable information to be available to end users wherever they are. The rise in mobility and multitude of devices has paved way for direct access to corporate information, which highlights the need of secure and consolidated network which can be scaled rapidly on-demand. The CIOs need to have complete visibility of all network assets and take decisions on network performance and network behavior dynamically. This can be achieved only through network consolidation.

Consolidating your network under one trusted service provider will ensure you a centralized real-time visibility and control over your entire network. Network consolidation improves network performance management and makes network provisioning easier with lesser handoff points between providers, devices, and IT assets, at a reduced cost!

With growing Internet infrastructure and new technologies, VoIP (Voice over Internet Protocol) has gained tremendous popularity among businesses. Regardless of size and industry, organizations are migrating their communication network from traditional PSTNs to VoIP. The wide-ranging benefits of the system are bound to attract businesses from across the board – reliability combined with steep cost savings and a plethora of productivity-enhancing features make it the communication network of choice for enterprises.

But, in today’s landscape of increasing cyber-attacks, VoIP must also strengthen its security protocols to ensure businesses are not left vulnerable to malicious cyber agents.

Main Security Threats faced by VoIP

VoIP networks are open to the following threats

• Identity and service threat – this usually involves eavesdropping and phreaking – Eavesdropping is a scenario in which attackers infiltrate the VoIP lines to listen in to conversations to gain access to sensitive business data or private information and accounts to carry out corporate sabotage or identity theft. Phreaking is a term used for the practice of passing off call charges to other accounts by getting unauthorized access to their VoIP service.
• Viruses and Malware – the bane of all Internet-based services – VoIP services are also open to attacks by malware, worms, and viruses.
• Denial of Service – Another threat that is used most often against Internet-based services – DOS can bring the communication network to a halt by flooding it with unnecessary messages.
• Call tampering – call tampering refers to the practice of interrupting the call by injecting noise packets in the network or withholding call packets to cause call delays and poor call quality. Call hijacking is another form of call tampering in which an outside party enters the call and tricks the person on the other line by masquerading as the original caller.

How are VoIP service providers countering these security challenges?

Service Providers understand that the continued popularity of VoIP services depends, to a large degree, on how secure and comfortable businesses feel while using these services. The VoIP providers and organizations have given top priority to securing their communication networks and have spent the considerable amount of effort and money in putting together some of the most cutting-edge security solutions to safeguard their systems.

The threats listed above can be taken care of by a judicious mix of preventive measures –

• SBCs (Session Border Controllers) – SBCs manage VoIP protocol signals and with in-built security firewalls they are the first and one of the most effective lines of defense against cyber threats.
• Anti-virus – installing and operating an updated anti-virus or anti-malware on all connected computer hardware is especially important as they can enter the VoIP network through unsecured channels.
• Encryption – usually provided by the service providers as an add-on service to secure the network and is highly recommended for enterprise users. VoIP encryption is especially important when the organization has many users connecting from outside the office network – from mobiles or from home devices.
• Call restrictions, authorization, and passwords – businesses must restrict access to the VoIP network by making sure that only the required people are given access to the network. This along with call restrictions, to track and monitor call activity and stringent password policies can ensure that people within the organizations are made aware of the importance of keeping the network secure.
• Deep Packet Inspection (DPI) – DPI monitors the network and can identify extra or fraudulent data packets and flag them for review.
• VoIP authentication protocols – the most stringent of these protocols is the so-called three-way handshake – Challenge-Handshake Authentication Protocol (CHAP) uses a three-step process to test the legitimacy of the incoming messages and is far superior to basic password protection which is widely used.

Conclusion

While the future of VoIP services is secure – the benefits of the technology ensures that – security concerns that have dogged all Internet-based services are also giving network engineers sleepless nights. From cloud platforms to on-premise IT infrastructures, all systems have vulnerabilities that can be exploited and as Cyber-attacks become more aggressive and better organized no one is truly safe.

It is estimated that the global cost of cybercrime will reach $2 trillion by 2019 – keeping these numbers in mind organizations can no longer count on just plain old luck to keep their businesses safe, they need to be prepared for the worst. And this is especially true for mission-critical functions like communication!

Here, VOIP is clearly the solution of choice for organizations looking for a secure communications network.

As more and more businesses, both big and small, are jumping on the VoIP (Voice over IP) bandwagon, it is interesting to examine what is causing this exodus from the traditional alternative of PSTN (Public Switched Telephone Network) including Mobiles and Landlines.

In order to understand the reasons for the switch, it is important to first appreciate what is significant for these businesses while opting for a communication system. The chief concerns for businesses, irrespective of their size, while choosing a network are,

• How to reduce costs and at the same time not compromise on the quality of the communication system.
• Is there a way that would improve communication with customers and employees and better connect them?
• How to achieve more value for your money and get additional features at the same cost.
• Can the communication system contribute to an increase in efficiency and productivity?

As VoIP addresses these concerns and provides a powerful tool for businesses to ‘up their game’, enterprises in increasing numbers are opting for this alternative.

Cost-Effective Choice

A VoIP solution has a definite edge over its PSTN alternative as it offers free CUG (VoIP-to-VoIP) calling for both local and international. The calls made to mobile and landline phones through VoIP have nominal subscription fees as against a much more expensive PSTN alternative. The sound quality is continually improving as the technology is evolving, providing superior communications and better filtering of background noise with VoIP. Its online conferencing and other features help reduce the requirement for travel. It also has a lesser bandwidth requirement (10 Kbps) than the PSTNs (64 Kbps).

Improve Communication with Customers and Employees

VoIP provides unified communication, helping the employees to work remotely from any place with an Internet connection and ‘take the office’ with them. It also provides the ‘presence’ technology that enables users to see if employees are available and accordingly get in touch with them. PSTNs on the other hand, are able to provide the remote extension facility only with dedicated lines for each extension and hence are very expensive.

More Value for Money

VoIP solution provides an ease of scalability without adding significant infrastructure and cost to the decision. Additionally, VoIP offers call waiting, call forwarding and call transfer options as a standard offering, but the same is available in PSTNs at an additional cost.

Increased Efficiency and Productivity

VoIP has an edge over its traditional counterpart as it allows businesses to get enterprise class software at an affordable cost. As the cost of scalability is low, even smaller businesses can enjoy customized solutions with many features as standard or as an affordable add-on. These lead to increased productivity, less down time, and hence more profit. However, as the service terminates when the Internet connectivity (power) is lost, organizations must have a VoIP backup plan. PSTNs, nevertheless, are able to continue service during power outages, as phone jacks do not require electricity.

Hence, traditional choices such as PSTNs are making way for VoIP as the latter are proving themselves as a powerful tool, giving the businesses a competitive edge and providing the ‘right-size’ technology at an affordable price.
