Resources | Guides | Coping with Network Disruption in a Cyber Attack

In today's interconnected world, network connectivity is the lifeblood of businesses and individuals alike. It enables seamless communication, access to critical resources, and the smooth functioning of various services.

However, the increasing frequency and sophistication of cyber attacks pose a significant threat to this essential network infrastructure. In this blog, we'll explore the repercussions of losing network access in a cyber attack and discuss strategies to cope with such disruptions.

The Impact of Network Disruption

When an organisation or individual falls victim to a cyber attack, the loss of network access can have far-reaching consequences. Consider the following implications:

  • Disrupted Operations: A compromised network can paralyse an organisation's operations, leading to a loss of productivity, missed deadlines, and financial setbacks. In some cases, critical services may become entirely unavailable, jeopardising customer satisfaction and trust.
  • Data Breaches and Loss: Cyber attacks often aim to steal or compromise sensitive information. Unauthorised access to databases or storage systems can result in data breaches, leading to reputational damage, regulatory penalties, and potential legal ramifications.
  • Communication Breakdown: Network disruption hampers communication channels, preventing employees from collaborating effectively and hindering customer support. This breakdown can exacerbate existing issues, prolong downtime, and weaken stakeholder relationships.

Coping Strategies

While the effects of a cyber attack can be devastating, there are several proactive steps you can take to minimise the impact and facilitate a smoother recovery:

  • Incident Response Plan: Develop a comprehensive incident response plan that outlines the steps to be taken in the event of a cyber attack. This plan should include strategies for isolating affected systems, notifying relevant parties, and restoring network access in a secure manner. Out-of-band crisis communications, independent of normal communication tools, can also support the ability to always communicate.
  • Redundancy and Backup Systems: Implement redundancy measures such as backup networks, independent crisis communication platforms and failover systems. Regularly back up critical data, test regularly the ability to restore and ensure these backups are stored securely in a different zone or location. Successfully restoring from a clean back up is essential and therefore it may be necessary to roll back to stored earlier versions as recents ones may be infected with the malware. These actions will enable you to recover swiftly from an attack and reduces the likelihood of permanent data loss.
  • Continuous Monitoring and Threat Intelligence: Employ robust security measures, including firewalls, intrusion detection systems, and antivirus software. Regularly monitor your network for any suspicious activities and stay updated on the latest threats through threat intelligence sources. Proactive monitoring helps identify potential vulnerabilities and strengthens your defences against cyber attacks.
  • Employee Education and Awareness: Educate employees about the risks associated with cyber attacks and the importance of following security best practices. The threat perimeter is across the whole organisation and not just the network servers. Conduct regular training sessions to enhance their understanding of phishing attacks, social engineering techniques, enforce strong passwords, multi-factor authentication and biometric ID on mobile applications. Encouraging a security-conscious culture can significantly reduce the likelihood of successful attacks.
  • Incident Recovery and Business Continuity: Develop a comprehensive incident recovery plan that focuses on restoring network access and resuming critical operations swiftly. Establish clear roles and responsibilities for team members involved in the recovery process and conduct regular drills to test the effectiveness of your recovery strategies.


In the face of escalating cyber threats, the loss of network access due to a cyber attack can be a severe setback. However, by implementing proactive security measures, educating employees, and developing robust incident response and recovery plans, organisations can mitigate the impact and enhance their ability to bounce back swiftly.

Remember, preparedness and a vigilant and holistic approach to cybersecurity are key to weathering the storm and emerging stronger from any network disruption caused by a cyber attack.
