The US government Cybersecurity and Infrastructure Security Agency has issued a range of security advisories:
Cisco Releases Security Updates for Multiple Products | CISA
Apple Releases Security Update for Xcode | CISA
OpenSSL Releases Security Update | CISA
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.
CISA also releases industrial control system advisories – if you are responsible for these types of systems you should monitor their news page:
