The US government Cybersecurity and Infrastructure Security Agency (CISA) is one of my trusted sources for cyber security information. They have recently added a number of known vulnerabilities to their Known Exploited Vulnerabilities Catalog – including, Veritas Backup Exec, Windows and the recently patched Apple vulnerabilities.

Cisco has issued security advisories and advice for a range of it’s security devices:

CISA also releases industrial control system advisories – if you are responsible for these types of systems you should monitor their news page:
My advice: Either you or your IT support need to check whether these issues impact your systems. You need to have a master document that details your systems, hardware, software, online, networks, back-ups, suppliers etc – so when cyber security (or operational) issues arise you and your support teams can quickly check if you are affected. From there you can take fast, effective action.
