Windows Security Advisory – Update for Minimum Certificate Key Length

In response to vulnerabilities identified in certificates using RSA keys which are less than 1024 bits in length, Microsoft has issued a Security Update (2661254). NCSC recommends that organisations maintain fully patched operating environments at all times, as outlined in the Top 35 Mitigation's. The update is now available for download, to allow for it to be fully tested prior to its wider October release.
