What do these terms mean?
  • What is a CVE?

    A CVE (Common Vulnerabilities and Exposures) is a public tracking number for a specific security flaw in software or hardware, similar to a SKU for a bug.

  • What is the CISA Known Exploited Vulnerabilities (KEV) catalog?

    The CISA KEV catalog is the U.S. government’s short list of vulnerabilities that attackers are actively exploiting in the wild — not just theoretical risks.

  • Who publishes Security Briefs on PremierePC?

    PremierePC tracks alerts from CISA KEV, Microsoft MSRC, FBI IC3 industry advisories, and other U.S. feeds, then summarizes impact in plain English for Upstate SC businesses.

  • How often are Security Briefs updated?
