What is a VPN?

• Virtual Private Networking (VPN) to transmit data
  over the Internet or managed IP-based network
• Tunneling
• Authentication
• Secure VPN adds
• Encryption
• Digital certificates
• Automates key management

38
Sound Security Characteristics

• Confidentiality
• 168-bit Triple DES encryption
• Integrity
• IPSec ESP encapsulation
• Authentication
• x.509 v.3 Digital Certificate Authentication
• IPSec Authentication Header (AH)
• Secure Hash Algorithm
• HMAC-SHA1
• HMAC-MD5

39
Secure VPN Standards

• Standards proposed by IETF IPSec working group
• Internet Key Exchange (IKE)
• IPESP, ESP Mode and AH Mode
• Full 56-bit DES and 168-bit Triple DES encryption
• X.509 v.3 Digital Certificates
• RSA and Digital Signature Standard (DSS)
• Secure Hash Algorithm (HMAC-SHA1) MD5
  (HMAC-MD5)
• RSA and Diffie-Hellman key exchange

40
IPSec VPN Standards

• Internet Key Exchange (IKE) is the mandatory
  IETF IPSec standard
• Enables companies to use single standard
  architecture
• Allows for a broad range of electronic commerce
  applications
• Interoperability with other vendorseventually

41
Secure VPN Standards

• Internet Protocol Encapsulating Security Payload
  (IPESP)
• Provides capability to use a remote IP address
  from a corporate LAN for remote users/units
• Benefits
• Strongest level of security
• Corporation can provide access to internal
  resources based on internal IP addresses
• Encapsulation of internal IP addresses allows
  for the routing of non-routable address
  spaceover the public network

42
How Does a Secure VPN Device Work?

• Prior to shipment, each Secure VPN hardware unit
  will generate a unique Public/Private Key and a
  X.509 v.3 Digital Certificate
• Enables authentication and access control of VPN
  units by a network administrator
