According to a recent report by Ericsson Mobility, 5G subscriptions are projected to reach 4.4 billion globally by the end of 2027, accounting for 48% of total global mobile subscriptions. The fast speed, low latency, and increased capacity of 5G networks are expected to bring numerous benefits. However, with every new technology, there are also new cybersecurity risks to consider.
One of the challenges posed by 5G networks is the sheer number of connected devices. As the number of devices increases, so does the potential attack surface for cybercriminals. Additionally, the rise of remote work has further exacerbated cybersecurity concerns. With employees using personal devices to connect to corporate networks, there is a higher likelihood of vulnerabilities and advanced persistent threats.
Another issue is the shortage of cybersecurity experts to monitor network traffic and address threats. Many organizations are understaffed in this area, making it difficult to identify anomalies and respond effectively to cyber threats. As attack surfaces expand, skilled IT staff becomes increasingly scarce. However, regardless of the size of the cybersecurity team, there are six key areas that organizations must focus on:
1. Awareness and Monitoring: It is crucial to have a thorough understanding of the attack surface and maintain up-to-date documentation of all connected assets. Using security information and event management (SIEM) software, rogue system detection devices, and vulnerability scanners can help in identifying potential risks.
2. Cybersecurity Training: Providing comprehensive training to the IT team is essential to enable them to recognize potential compromises and know how to report and escalate responses when needed.
3. Impact Reduction: Limiting sensitive information and connectivity to vulnerable systems is essential. Developing a well-trained incident response plan, whether in-house or with a third-party, can help address cyber threats efficiently.
4. Vulnerability Management: Implementing a vulnerability management program can help collect information on the latest threats and vulnerabilities. This program should include threat intelligence gathered through a vulnerability scanner tailored to the organization’s network.
5. Threat Information Sharing: Participating in threat information sharing platforms such as the Cybersecurity and Industrial Security Agency’s Automated Information Sharing program and the Cybersecurity Incident Response Center’s (CIRCL) Malware Information Sharing Platform (MISP) is highly recommended to stay updated on emerging threats.
6. Incident Response Training: Prioritized training for SOC/NOC personnel is essential to equip them with the necessary skills to conduct the processes outlined in the incident response plan. Regular reviews of the vulnerability management plan should also be conducted to ensure its accuracy in addressing vulnerabilities.
While new technologies bring advancements in communication and computation, they also introduce new vulnerabilities. It is crucial for organizations to automate network security using SIEM, rogue system detectors, and vulnerability scanners to proactively identify potential threats. For organizations lacking cybersecurity personnel or the necessary tools, outsourcing these responsibilities to a third-party security provider can be an effective solution. These providers bring cost, scale, and expert knowledge advantages to the table and can often be more cost-effective than hiring a highly-trained cybersecurity professional.
As the perimeter of enterprise networks expands beyond corporate walls, a skilled cybersecurity team and advanced automation tools are necessary to mitigate risks and reduce attack surfaces. By implementing proactive cybersecurity measures and staying informed about emerging threats, organizations can protect their networks and data in the age of 5G.
