  1. Computer Security Beyond the Serpentine Walls New Horizons Conference May 23rd, 2007 Shirley Payne & Marty Peterman UVa IT Security and Policy Office

  2. Agenda • Vulnerabilities and Risks • Tips and tools before you go • Device Requirements on the road • Checklist • Q&A throughout

  3. Serious Security Vulnerabilities • Out of date software • Lack of effective anti-virus and anti-spyware software • Weak security settings on browsers • Weak passwords • Software firewalls not activated

  4. Serious Security Vulnerabilities - continued • Unencrypted sensitive data • Use of unsecured wireless • Use of improperly maintained public computers • Unattended mobile devices and electronic media

  5. Risk of Exploited Vulnerabilities Can Vary With Location • University provides: • “More Secure Network” that prevents certain attacks • Automatically updated software • Encrypted wireless network (“cavalier” & “jefferson”) • Encrypted wired connection to email, home directory, and other services

  6. Contrast to….

  7. Or...

  8. Vulnerabilities Increase the Risk of: • Mobile devices being stolen • Computer being rendered unusable by virus or worm • Private data being captured by stealth, keylogging software • Sensitive data being copied, modified or deleted by or exposed to unauthorized individual

  9. Risk To Sensitive Data Is Huge! • A total of 1.9 billion reported compromised records from 1980-2006¹ • Trend is toward: • More sophisticated criminal attacks • Increasing # of incidents where motive is exploit of personal data for profit • However, there are many steps individuals can take to prevent such attacks ¹Source: Phil Howard & Kris Erickson, University of Washington study, March 12, 2007

Before You Go, Prep for Secure Remote Access • Install UVA-Anywhere to enable: • Remote use of the Home Directory Service • Access to UVa-licensed online databases, news resources, and software • Encrypted data transmission • Access to UVa Email server without reconfiguration • Tips and tool - http://www.itc.virginia.edu/network/vpn/

  15. Off You Go!

  16. When On The Road, • Be wireless wary. Prevent unintentional connections to untrustworthy wireless networks • Disable file and print sharing • Device Requirements - http://www.itc.virginia.edu/security/
