“Casual Intruder - Disgruntled Employee” • Shoulder surfing co-workers • Finding written password • Post-It Notes • DayTimer • Guessing password • “password” • Spouse/Dog/Kid’s name • Username
“Serious Hacker” • All of the “casual” approaches • “Social engineering” • Password cracking • “Crack” • “L0phtCrack” • “Cracker Jack” • Network sniffing
Passwords Are Not Secure • Tools for defeating passwords abound • Compromise is not detectable • Passwords can be snooped off the Net • Passwords & files are diverted off desktopsor servers • Password protected credentialsare compromised off-line
“Privacy” is NOT “Security” Encrypted Tunnel Through Public Network ? Who’s at the other end of the line?

Secure Remote Access • Let’s look at reducing the risks and complexity
Internet The Internet Simplifies Remote Access Global Access delivered by ISP
Reducing The Risks? • The Internet is a collection of unsecured networks! • Strong Authentication and Encryption can provide a solution • New Technology • VPN
What is a VPN? • VPN - “Virtual Private Network” • Transport encrypted information via the Internet and public networks • Offer benefits of private network using “free” Internet infrastructure • Encryption means privacy not security • A VPN can be owned and run locally, or delivered as a service from a Telco or ISP
Secure VPN Send Session Key Request Passcode Request Connection PIN + Send Passcode Creating a Secure VPN ACE/Server Firewall or RAS server Internet
Internet VPNs Reduce Cost and Complexity • Reduce leased line costs and dial access charges • Reduce user support • Simplify remote access architecture • Reduce help desk services • Allow tracking / billing for usage • Reduce equip. costs for remote access

What about Certificates for Authentication? • A Digital Certificate is a unique electronic identifier (complex password) associated with a user • Browsers use certificates widely for establishing a level of authentication • More and more applications will use certificates • Email, SSSO, E-commerce • A user’s certificate can be used to check a Digital Signature - a unique electronic signature associated with the owner of the certificate • essential for non-repudiation of messages and transactions
How can we be sure of a Certificate? • A certificate is usually ‘signed for’ electronically by a Trusted Third party, e.g. Verisign • I.e. Two companies trust the integrity of a certificate issued by a jointly trusted external organisation • Today most Certificates are stored electronically on servers (e.g. LDAP) • So how can we be sure that the person who is using a certificate is who they say they are! • We Cannot unless they use Strong Authentication! ?
Smartcards for Security • Benefits • Two Factor ‘Strong Authentication’ • Secure storage of Private Credentials • Building Access • Photograph • Other Applications • Downside • Readers • Infrastructure
Soft Smartcards • Host based secure electronic ‘wallets’ (or files) that contain a users security credentials • Downloaded to the user on successful authentication • Two Factor Authentication to access Soft Smartcard • Excellent transitional solution to help companies migrate to smartcards for network access • Available today
PIN + Soft Smartcards for Secure Applications Access User dials-in Request for Passcode User Sends Passcode Authenticates and Credentialsdownloaded
Summary • Local and Global Electronic Commerce can • increase productivity and communication • reduce costs of doing business • deliver competitive advantage • Suffers from risk of abuse and fraud if not prudently secured • User Authentication, Encryption of traffic and use of Certificates can deliver very secure applications including E-Commerce
