The UK Government has recently designated data centers as Critical National Infrastructure (CNI), marking the first time since 2015 that such a classification has been made. This move means that UK data centers will now have a direct line to the Government to prepare for and respond to threats, similar to other critical sectors like energy, water, transportation, health, and communication.
This designation highlights the crucial role that data centers play in modern society and underscores the increasing risks faced by IT infrastructure in today’s ever-evolving cyber landscape. Cyber threats are constantly evolving, with cybercriminals becoming more sophisticated in their methods of infiltration and disruption.
As cyberattacks become more common and sophisticated, cybersecurity teams need to address threats across various fronts, including physical infrastructure, third-party suppliers, and personnel. Utilizing advanced cybersecurity technologies, strong policy and governance procedures, and providing employee cyber training are essential steps in mitigating these risks.
Hackers are now targeting Internet-connected UPS systems, often exploiting unchanged default usernames and passwords. UPS systems are crucial for compensating for primary power source failures in critical infrastructures, but their Internet connectivity also makes them vulnerable to cyber attacks. It is important for teams to effectively manage UPS environments to prevent compromises.
Additionally, malicious actors have shown that they can exploit weaknesses in data center infrastructure managed by third parties. By targeting vendors with privileged access to networks, hackers can gain entry to sensitive parts of a data center’s infrastructure. Collaboration between data center teams and third-party vendors is crucial to ensure the security of systems and networks.
To enhance cybersecurity across data centers, teams can take steps such as strengthening network perimeters, ensuring full visibility of assets, keeping software updated, and regularly scanning for insecure ports. Developing a cybersecurity-aware workforce through continual employee training is also vital in maintaining a secure cyber environment.
With UK data centers now recognized as part of the nation’s critical infrastructure, cybersecurity teams are likely to face an increasing number of threats and attacks. By implementing technical safeguards, managing networks effectively, and prioritizing security at the core of operations, UK data centers can continue to provide critical services, power the digital economy, and safeguard personal information.
