Cyber security is often discussed in terms of prevention: strong passwords, security software, staff training and keeping systems up to date.
But what happens when those measures aren’t enough?
Anyone who has experienced a cyber attack will know that the impact can extend far beyond the initial technical problem. Operations can be disrupted, customers may be affected, financial losses can mount and the people dealing with the incident can face considerable pressure.
The National Cyber Security Centre (NCSC) has published response and recovery guidance designed to help organisations navigate the aftermath of a serious cyber incident.
The guidance provides a framework covering three key stages: immediate response, recovery and organisational rebuild.
1. Immediate Response
The first few hours following a cyber attack can be chaotic.
The NCSC emphasises the importance of business leaders maintaining a calm and professional approach. While an attack will naturally create pressure and uncertainty, clear leadership can help improve decision-making and limit the attacker’s ability to exploit the situation.
Some of the recommended immediate actions include:
- Establishing an incident command structure.
- Bringing in an NCSC-assured cyber incident response provider where appropriate.
- Deciding whether systems should be disconnected or shut down.
- Assessing the current operational position.
- Identifying any immediate regulatory or other reporting requirements.
- Reporting the incident to the NCSC.
- Creating a central record of what is happening and decisions being made.
- Establishing clear communication with key stakeholders.
The priority at this stage isn’t necessarily to fix everything immediately. It’s to understand what has happened, contain the situation and establish control.
2. Recovery and Investigation
Once the organisation is confident that the attacker has been removed from the network, the recovery process can begin.
However, the NCSC warns that recovery can take longer than businesses initially expect.
Rather than treating recovery as a series of ad-hoc IT tasks, the guidance recommends managing it as a formal programme with:
- Clear ownership.
- Defined responsibilities.
- Appropriate decision-making authority.
- Structured planning.
- Ongoing investigation.
This approach can help ensure that the business isn’t simply restoring systems as quickly as possible, but is doing so safely and with a clear understanding of what happened.
3. Rebuilding the Business
Eventually, the business needs to move beyond crisis response and return to normal operations.
But the rebuild phase isn’t simply about switching systems back on.
It’s an opportunity to consider what can be improved so that the business is more resilient if another incident occurs.
This could involve reviewing:
- Cyber security controls.
- Business continuity arrangements.
- Backup procedures.
- Access permissions.
- Staff training.
- Incident response plans.
- Communication procedures.
- Critical business systems and dependencies.
The aim is to come out of the incident stronger and better prepared.
Don’t Forget the People
Cyber attacks can place enormous pressure on the people dealing with them.
Long hours, uncertainty, customer concerns and the pressure of making critical decisions can take their toll.
The NCSC therefore also highlights the importance of supporting the people involved in responding to and recovering from an incident.
Giving staff appropriate time and support to recover is an important part of the overall recovery process.
Could Your Business Keep Operating?
One useful exercise for any business owner is to consider what would happen if your critical systems suddenly became unavailable.
Ask yourself:
- Could you still access customer information?
- Could you continue invoicing?
- Could staff communicate with customers?
- Could you process payments?
- Do you have access to essential backups?
- Who would take charge if a serious incident occurred?
- Who would you contact for specialist help?
- How would you communicate with customers and suppliers?
You don’t need to wait until an attack happens to answer these questions.
Final Thoughts
Cyber attacks can be hugely disruptive, but having a clear response and recovery plan can make it easier to navigate the crisis.
The NCSC’s guidance provides a useful framework for thinking about what needs to happen immediately, how recovery should be managed and how the organisation can rebuild afterwards.
For businesses of all sizes, cyber resilience isn’t simply an IT issue. It’s part of business continuity and protecting the ability to keep operating when something goes wrong.
If you want to review your own business continuity arrangements or understand what you should have in place before a cyber incident occurs, now is a good time to start.
