Remote Access to Virtual Private Network (VPN)
Telecommuter, teleworker,  remote access user... What is technology behind these words?
  1. VPN, or Virtual Private Network refers to simulating a private network over the public Internet by encrypting communication between the two private end-points.
  2. Protocols (most common):
    • IP Sec (Internet Protocol Security) - a set of protocols developed by the IETF to support secure exchange of packets at the IP layer. IPsec has been deployed widely to implement Virtual Private Networks (VPNs).
    • SSL (Secure Socket Layer) VPN - a protocol that guarantees privacy and data integrity between client/server applications communicating over the Internet.
  3. Authorization - the process of granting or denying access to a network resource.
  4. Secure Authentication - the process of identifying an individual, usually based on a username and password.
What do you need to have as a user to work remotely?
1) RSA SecurID token - provided by an employer.
The SecurID technology generates a unique pattern of six digit keys which change every sixty seconds to produce a one-time-password (OTPW) when combines with a user PIN. The RSA SecurID token is available as hardware and software:

Hardware Tokens

To access resources protected by the RSA SecurID system, users simply combine their secret Personal Identification Numbers (PIN’s) (something they alone know) with the token codes generated by their authenticators (something they have). The result is a unique, one-time-use passcode that is used to positively identify, or authenticate, the user. If the code is validated by the RSA SecurID system, the user is granted access to the protected resource. If it is not recognized, the user is denied access.

Software Authentication

RSA SecurID software tokens use the same algorithm as RSA SecurID hardware tokens while eliminating the need for users to carry dedicated hardware devices. Instead of being stored in RSA SecurID hardware, the symmetric key is safeguarded securely on the user’s PC or smart phone. RSA SecurID software authenticators help to more effectively manage cost while reducing the number of items needed to gain access to the network or corporate assets, and eliminating the need for replacement tokens in the event of someone leaving the company or losing a token.

Software Tokens for smart phones



RSA SecurID software tokens are available for a variety of smart phone platforms including BlackBerry®, iPhone®, Windows®Mobile, Java™ME, Palm OS and Symbian OS and UIQ devices.






2) Software for authentication: Cisco ClientVPN - need to be installed on your PC or smartphone.
