Major Cyber Security Threats in Telecom and Ways to Mitigate them

22-06-2022 Aesthetix

Communication networks must be dependable. The present extent, diversity, and complexity of cybersecurity threats are expanding dramatically. The increasing number of data transfers, legacy technology, signalling protocols, the expanding role of cloud technologies, and "outdated" DNS and DDoS attacks are among the most prevalent "bullets" that telcos must avoid daily. Let's focus on the most important of them.

1) DDoS:

Advanced distributed denial of service (DDoS) attacks utilizing conventional network protocols and botnets comprising hacked mobile and IoT devices are prevalent. A DDoS is a Dedicated Denial of Service, which is an assault that disrupts regular traffic and, thus, denies service to the victim. This service outage might cause a business to incur severe financial losses.

DDoS assaults are brutal to prevent or defend against. Create a disaster recovery strategy in collaboration with your IT and cybersecurity professionals, and consider how you may respond to a DDoS attack. Due to the complexity of each organizational setting and how data is handled, there is no solution capable of preventing an attack.

2) DNS:

DNS (Domain Name Security) assaults continue to be a significant pain point for telecommunications companies. Worse, the cost of such attacks is increasing year by year. Cache poisoning, rebinding assaults, and domain lockups are the most common.

Reliable methods to prevent DNS assaults consist of proactive cyber resilience measures, such as identity management solutions for admin and server access. Similarly, you can augment firewalls with machine learning-driven policies.

3) IoT (Internet of Things):

How the Internet of Things (IoT) will affect the industry is one of the most critical obstacles facing Telco and Internet Service Providers (ISPs) in the current environment. The application of IoT to linked devices has exploded, providing more entry points in the process. Not all of these vulnerabilities are effectively fixed, exposing user, client, and company accounts.

The telecom business must use online data protection measures such as virtual private networks (VPNs), SIM-based authentication procedures, and identity management solutions. VPN establishes a safe connection to the internet by routing data traffic through an encrypted virtual tunnel. It masks the user's Internet Protocol (IP) address, safeguarding them from external threats.

4) Cloud security threats:

Some typical cloud security concerns are misconfiguration, data leaks, insider threats, lack of cloud security infrastructure and strategy, inadequate key management, and weak control planes.

It is essential to monitor employee cloud usage and apply precautions to prevent cloud data loss. In addition, risk can be reduced by controlling mobile devices and defining permissions for the company and user-owned endpoints, such as workstations, laptops, and cellphones.

5) Insider threats:

While some attacks in the telecom business are vindictive, many employees and insiders are unaware that they even pose a threat. Additionally, few individuals receive training on telecom security procedures. With as much as 30 percent of telecom employees working remotely, connections to insecure networks are at an all-time high.

In line with this, empirical research reveals that despite being aware of the hazards, people continue to connect to unsecured Wi-Fi networks, primarily for convenience. Unfortunately, a large number of programmes do not encrypt the data that their users send. Biometric security is a component of cloud-based authentication, a countermeasure to this issue. It safeguards your data regardless of where your users or workers connect.

6) Third-party risks:

Third parties such as suppliers, partners, email providers, service providers, web hosting, law firms, information management enterprises, and subcontractors might offer an attacker a backdoor into your critical infrastructure.

Maintaining the security of your company and the service providers in your industry might be difficult. Managed telecommunications security services are necessary for network-wide monitoring.

7) Terrorism and state actors:

Malicious actors can restrict the critical infrastructure's physical factors through remote intrusion and control the outcomes. They can collect vital information regarding intellectual property, trade agreements, and personal information. Since highly sophisticated threat groups carry them out, there is a strong probability that many successful telecom infrastructure breaches are never identified.

Always be careful of identity fraud to combat terrorist and state actor threats. Comprehensive solutions, such as premier identity proofing solutions, enable background check capabilities to validate identities and provide assurance for everyone in your system.


Telecom players have both an exciting and complicated period ahead. The sector is witnessing substantial alterations due to new assets such as IoT devices, leading to new income prospects and value streams.

To have robust and reliable telecom security mechanisms, you will need to convert from reactive security to proactive – one that relies on extensive monitoring and has predictive capabilities fueled by modern analytics and AI. Conduct through risk assessments for present systems, decentralize and automate the critical security requirements with appropriate tools and do even deeper checks for new technologies such as IoT and 5G.
