From National Cyber Security Centre:
Following Russia’s unprovoked, premeditated attack on Ukraine, the National Cyber Security Centre continues to call upon organisations in the UK to bolster their online defences.
The NCSC – which is a part of GCHQ – has urged organisations to follow its guidance on steps to take when the cyber threat is heightened.
While the NCSC is not aware of any current specific threats to UK organisations in relation to events in and around Ukraine, there has been an historical pattern of cyber attacks on Ukraine with international consequences.
The guidance encourages organisations to follow actionable steps that reduce the risk of falling victim to an attack.
