What security measures does the eTSC website employ?

The eTSC website supports industry standard best practices for Internet security. These practices include using the following:
  • The Transport Layer Security (TLS) encryption protocol uses a mathematical process that transforms a message to conceal its meaning and to protect the integrity and authenticity of the message. Traffic between your browser and our server is encrypted using the industry standards ensuring that your information is kept secure and private. Note that the Secure Socket Layer (SSL) protocol is no longer supported to access the eTSC website.
  • A trusted third party digital certificate is used to verify the identity of the eTSC website. The role of a digital certificate is similar to an ID card ensuring that the website is authentic. It is your responsibility to make sure that the digital certificate is valid.
  • Firewalls block an array of threats, such as hackers, viruses and other security threats. Firewalls also monitor traffic to and from our servers to ensure there are no interruptions due to malicious activities.
  • An intrusion detection system monitors the website for network and system breaches caused by malicious actions or policy violations.
  • Routinely applying patches and updates to the software supporting the website to close identified security holes.

How can I verify that my communication with the eTSC is secure?

The URL of a secure communication begins with "HTTPS://" - the additional "S" on the end of the familiar HTTP protocol indicates a secure communication channel to the server. Also, in most current browsers, a padlock icon will be visible to the right or left of the URL to view digital certificate and encryption algorithms used. The URL for the eTSC website is HTTPS://

Why do I need to use a particular browser?

To maximize the privacy of your information and application functionality, the browser you use must support JavaScript, cookies, and the Transport Layer Security (TLS) protocol. Your operating system and browser should be supported by the manufacturer and be updated with the latest service pack and/or security patches. Your operating system and browser work hand-in-hand to prevent security breaches. Not using the latest version of a web browser increase your risk of exposure when traversing the Internet.
