Telecom Industry Cybersecurity Solutions for Network and Data Protection

The telecommunications sector provides communications, information, media, content, and entertainment services to homes and businesses. For telecom providers, cyber security is of strategic importance because of their large and frequently expanding attack surface with millions of endpoints, nodes and a very wide variety of servers and databases. Growth through frequent acquisition amplifies telecom cyber security challenges.

The combination of a wide attack surface and an innate intolerance for service disruption makes telecoms an attractive target for financially motivated threat actors. Telecoms face an increasing range of cyber threats that includes ransomware, phishing and credential harvesting, exploitation of network software vulnerabilities, man-in-the-middle attacks, data exfiltration, and Distributed Denial of Service (DDoS) attacks.

Nation-State Attackers

Due to the central role of the services that telecoms provide, and the sensitive data they manage, hostile nation-state threat-actors frequently try to disrupt their operations or gather intelligence. Nation-state threat-actors operate on a larger scale, and deploy different and highly advanced tactics, techniques, procedures, and methodologies usually stealthily over a much longer time horizon.

Telecom Cybersecurity Challenges

Securing Software-driven, Cloud-based Networks

To stay competitive and profitable, telecoms seek to maximize agility while minimizing OPEX and CAPEX. They are moving as much network functionality as possible from hardware to disaggregated, software-based, and applications that run on standard networking white boxes. Communications software developers typically leverage containers and Kubernetes to enable automation of network deployment and scaling. 5G networks, with their distributed cloud-native architectures, are a prime example of this evolution. As the telecommunications sector moves to software-driven platforms in both the network core and edge, threat-actors have a wider range of entry points and systems they can impact. Disaggregated networks also rely on a broader software supply chain. Telecom cyber security teams need to ensure that this rapidly evolving attack surface is robustly protected.

Securing Sensitive Data

Telecoms hold a range of sensitive data including personally identifiable information (PII), customer contact information, call and billing data, and device details. Telecoms also hold valuable customer location details, demographic data, and information about subscriber online activity and service consumption. To prevent exfiltration and corruption of this highly sensitive data, telecoms need to both prioritize proactive cyber security measures to prevent breaches and enhance their ability to rapidly detect and eradicate attackers that evade defenses.

Securing Legacy Systems

Telecoms typically upgrade infrastructure gradually due to the large scale and high cost of network hardware and software. They typically continue to operate legacy equipment and databases, including end-of-life equipment that can be very difficult to secure against the latest threats. Telecom cyber security teams need to implement compensating controls that include isolation of legacy systems, disabling unnecessary services they provide, MFA, and adoption of zero trust models. Incident response plans and backup and recovery plans are critical.

Early Threat Detection & Rapid Response

In addition to protecting sensitive customer data, telecoms are expected to provide 24×7 service. To enable a swift and decisive response to any security breach, telecoms must have a robust 24/7/365 threat detection and response capability.
