[NCSC Guidance Feed] Actions to Take When the Cyber Threat is Heightened

As the cyber threat landscape continues to evolve, organisations must remain vigilant and proactive in their approach to cybersecurity. The National Cyber Security Centre (NCSC) provides guidance on the actions to take when the cyber threat is heightened, helping organisations to improve their security posture and reduce the risk of a successful cyber attack.

Understanding the Heightened Cyber Threat

The cyber threat is heightened when there is a significant increase in the number of cyber attacks, or when a specific threat actor is known to be targeting organisations in a particular sector or region. This can be due to a variety of factors, including the use of new and emerging technologies, the exploitation of known vulnerabilities, or the targeting of specific industries or sectors.

Identifying the Heightened Cyber Threat

Organisations must be able to identify when the cyber threat is heightened, and take appropriate action to improve their security posture. This can be achieved by:

Monitoring threat intelligence feeds to stay informed about the latest cyber threats and vulnerabilities
Conducting regular security assessments to identify vulnerabilities and weaknesses in the organisation's systems and processes
Implementing incident response plans to quickly respond to and contain cyber attacks
Providing regular security awareness training to employees to educate them on the latest cyber threats and how to prevent them

Actions to Take When the Cyber Threat is Heightened

When the cyber threat is heightened, organisations must take immediate action to improve their security posture. This can include:

Implementing additional security controls such as firewalls, intrusion detection systems, and antivirus software
Conducting regular vulnerability scans to identify and patch known vulnerabilities
Implementing a web application firewall to protect against web-based attacks
Enabling multi-factor authentication to add an additional layer of security to user accounts
Conducting regular penetration testing to identify vulnerabilities and weaknesses in the organisation's systems and processes

Implementing a Cyber Security Incident Response Plan

A cyber security incident response plan is a critical component of an organisation's overall security strategy. This plan outlines the procedures to be followed in the event of a cyber attack, and ensures that the organisation is prepared to respond quickly and effectively.

Key Components of a Cyber Security Incident Response Plan

Incident classification: a clear definition of what constitutes a cyber security incident, and how it will be classified
Incident response team: a team of individuals responsible for responding to cyber security incidents
Communication plan: a plan for communicating with stakeholders, including employees, customers, and partners
Containment and eradication: procedures for containing and eradicating the cyber attack
Recovery and post-incident activities: procedures for recovering from the cyber attack, and conducting post-incident activities

Conclusion

The cyber threat is a constant and evolving threat to organisations, and it is essential that they remain vigilant and proactive in their approach to cybersecurity. By understanding the heightened cyber threat, identifying the threat, and taking immediate action to improve security posture, organisations can reduce the risk of a successful cyber attack and protect their assets.
