National Cyber Awareness System
Four products in the National Cyber Awareness System offer a variety of information for users with varied technical expertise. Those with more technical interest can read the Alerts, Current Activity, or Bulletins. Users looking for more general-interest pieces can read the Tips.
Current Activity updates provide timely information on security risks to help you better protect your systems from malware campaigns and mitigate against new software vulnerabilities. Current Activity is updated frequently and typically contains less detail than Alerts.
Alerts warn about vulnerabilities, incidents, and other security issues that pose a significant risk. Alerts contain more detailed information and are not issued as frequently as Current Activity updates.
Bulletins provide weekly summaries of new vulnerabilities. Patch information is provided when available.
Tips provide advice about common security issues for the general public.
