Cyber Security Alerts outline the steps and actions that non-technical home and corporate computer users can take to protect themselves from attack. Cyber Security Tips describe and offer advice about common security issues for non-technical computer users. Tips are restricted to a single topic, although complex issues may span multiple tips. Each tip builds upon the knowledge, both terminology and content, of those published prior to it. en-us Produced 2009 by US-CERT, a government organization. 2009-07-01T17:36:41+00:00 info@us-cert.gov http://www.us-cert.gov/cas/tips/ST04-005.html Understanding Anti-Virus Software http://www.us-cert.gov/cas/tips/ST04-004.html Understanding Firewalls http://www.us-cert.gov/cas/alerts/SA09-160A.html Microsoft Updates for Multiple Vulnerabilities http://www.us-cert.gov/cas/tips/ST04-003.html Good Security Habits http://www.us-cert.gov/cas/tips/ST04-002.html Choosing and Protecting Passwords http://www.us-cert.gov/cas/alerts/SA09-133B.html Adobe Reader and Acrobat Vulnerabilities http://www.us-cert.gov/cas/alerts/SA09-133A.html Apple Updates for Multiple Vulnerabilities http://www.us-cert.gov/cas/alerts/SA09-132A.html Microsoft PowerPoint Multiple Vulnerabilities http://www.us-cert.gov/cas/tips/ST04-001.html Why is Cyber Security a Problem? http://www.us-cert.gov/cas/tips/ST06-003.html Staying Safe on Social Network Sites
