Answering Your Questions

What are the different forms of internet security available?

SSL (secure socket layer) Encryption Technology - This is the basis for all Internet security.

  • SSL creates a secure point-to-point connection between your browser and another party’s server, in this case, TDFX.

SSL Provides the Following Functions:

  • Authentication: verifies you are not visiting an imposter’s web site.
  • Message Privacy: All information sent between you and TDFX is automatically encrypted.
  • Message Integrity: SSL is able to determine if a single character in your request has been changed so that each party knows that what they’re seeing is exactly what was sent.
  • There are two different levels of SSL encryption used to secure today’s Internet communications, 40-bit and 128-bit.

Which level of security does TDFX use and why?

TD Securities has placed a great deal of effort ensuring the integrity of the data you transmit on-line to us and in preserving the confidentiality of your transactions. Our security procedures include:


  1. TDFX uses 128-bit SSL encryption technology, the most powerful cryptographic software available today.
  2. Unique user ID’s are assigned to each client and will be disabled after multiple failed login attempts.
  3. Ensuring that passwords created by you are encrypted, are of a minimum length, and are non-repetitive.
  4. The use of TD Bank Group’s trusted Internet and firewall protocols currently in use today when you bank or trade on-line. These protocols are continuously monitored and are independently verified.

How do I know if a website is secure?

Three quick clues you can use to determine if a web site is secure:


  1. The web site address begins with "https" (Secure Hyper Text Transfer Protocol) rather than the more common "http".
  2. The padlock in the lower left-hand corner of the navigator window of Netscape Communicator and Microsoft Internet Explorer will be closed.
  3. Microsoft Internet Explorer browsers have built-in security mechanisms that notify you with a warning message before you try to send information to an unsecured site.

How do I determine what browser version I have and the level of security it supports?

Microsoft Internet Explorer:

  • Go to the Help menu and select About Microsoft Internet Explorer
  • At this point there will be a statement indicating the browser version. If the cipher strength is 128-bit, then you are ok.

To Upgrade:

  • Link to Microsoft Internet Explorer Upgrade
  • Select either the browser version you wish to upgrade to, or the Internet Explorer High Encryption link to upgrade your existing browser to support 128-bit encryption
  • Follow the directions for install

Log out of the Internet and then log back in for the upgrade to take effect.
