Active Cyber Defence (ACD) · the fourth year

Source NCSC UK

Description

The year four report covers 2020 and aims to highlight the achievements and efforts made by the Active Cyber Defence programme.

Impact

No direct impact from a specific vulnerability or exploit is described. The report reflects ongoing national cyber defence efforts aimed at reducing the harm caused by cyber attacks across the UK. It mentions involvement in responding to the SolarWinds Orion compromise but does not detail any new vulnerabilities or active exploits. Therefore, no immediate impact on systems or users can be inferred from this report alone.

Defensive guidance

As this is a programme report rather than a description of a specific vulnerability, no direct mitigation actions are applicable. The report emphasizes the continued use and development of ACD tools and services to protect UK organisations. Stakeholders should refer to the NCSC for specific guidance and updates on any vulnerabilities or threats identified through the ACD programme. Patch status or remediation details are not applicable here.
