Internet Banking security

Security overview
There are three main areas of security involved in Internet Banking.

The Bank, the Internet and your computer.

The Bank
To ensure your personal information is kept safe we have built a secure connection between our bank systems and the Internet. This connection is secured by what is called a firewall.

Our security team constantly monitors our systems for suspicious activity and automatic alerts are generated if any abnormal activities arise. We also subscribe to services that regularly report on any potential vulnerability so we can take action to ensure new security risks are not opened.

The Internet
When your account information is transmitted over the Internet, it is protected from unauthorised access by a method called encryption. Encryption is a technique of coding the information being sent using random mathematical 'keys' so that only you and the bank's systems can readily unscramble the information. These keys are generated each time you sign into Internet Banking and are destroyed when your session is terminated (when you sign out). There is also a random token generated when signing in that your browser must always return to be able to talk to our system.

Your computer
Your account details are protected by your customer number and password. We encourage you to change your password frequently.

Privacy
We are committed to your privacy, and the responsible use of information. Read our
privacy policy or go to the Internet Banking terms and conditions.

Protection of my personal information

  • Password security
    In the past, hoax emails have been sent to some customers from other financial institutions requesting they supply their Internet Banking sign in details. Westpac will never ask for your customer number or password via email for Internet Banking. If you receive such an email, do not respond and delete it immediately.

    Other hoax emails request you to sign in to Internet Banking at a false website. Always make sure you sign in to www.westpac.com.fj when using Internet Banking.
  • Account information
    Westpac has implemented rigorous security mechanisms to ensure that your information and accounts are protected. The latest strong encryption technologies have been used to protect your data when being sent over the Internet, and the Westpac Internet Banking site uses public/private certificates to generate the security keys for your individual session. By doing this you can verify you are connected to the Westpac web site.

    Access to your account information is controlled using your customer number and password and it is therefore very important for you to protect your password. As information sent between your browser and the bank is encrypted, it makes it very difficult for anyone to get your password from the Internet. It would be easier for someone to obtain your password by guessing an easy password (e.g. your birth date), or by stealing your password (if you had written it down), or by watching you type in your password.

    You should choose a password that cannot be associated with some of your known personal information. Never disclose your password to anyone (not even someone claiming to be from the bank), and don't write it down or store it on your computer. Most importantly, change your password regularly.

What should I do to ensure my privacy is protected?

  • Always sign out of Internet Banking. You must sign out of Internet Banking to close the active session. If you do not sign out, but merely close the browser window the Internet banking session will remain active on the hard drive [for 7 minutes]
  • Close your browser at the end of each Internet Banking session
  • Change your browser settings so that the secure pages you access are not saved on the hard drive
  • Regularly change your password

How do I change my browser settings?
If you have Microsoft Internet Explorer 4, start by selecting View
If you have Microsoft Internet Explorer 5, start by selecting Tools
Then follow these steps for both versions:

  1. Select Internet Options
  2. Choose the tab labelled Advanced
  3. Tick the boxes stating Do not save encrypted pages to disk and Delete saved pages when browser is closed (version 4) or Empty Temporary Internet Files folder when browser is closed (version 5)
  4. Click on OK

Please note: Netscape 6.2 and 7.0 are set by default to not save secure information on the hard drive

What do I do if I think someone is using my accounts?
You will need to contact our Customer Service Representatives immediately. As a precaution, you should verify all transactions viewed in Internet Banking against paper-based statements issued on accounts. If necessary, you can order up to date statements. This should assist you in spotting any suspicious transactions.

What technologies are used to protect my data?
The secure connection between your browser and the Westpac Internet Banking system uses a technology called Secure Sockets Layer (SSL). This is a well-respected technology developed by Netscape, Microsoft and RSA Inc that is supported by most browsers.

In the changing world of technology, Westpac understands that while this technology is suitable for today, newer technologies may provide stronger security, better efficiency and greater convenience in the future. Hence we are constantly reviewing newer technologies as they mature and become available.

How to tell if your data is encrypted

Check for the SSL secure connection symbol
When you sign into Internet Banking a secure session will be established between your computer and the bank. You will not be able to connect to the Internet Banking sign in page unless your browser connects with full 128-bit SSL encryption. You can confirm your Internet Banking session is encrypted by the appearance of a symbol at the foot of the browser.

The following table shows the various symbols that appear in different browsers when the data is being encrypted. This symbol should always be displayed when using Internet Banking:

  Data Encrypted Symbol Data NOT Encrypted Symbol
Netscape Navigator Netscape data encrypted symbol Netscape data not encrypted symbol
Internet Explorer Internet Explorer data encrypted symbol No symbol shown

Check the strength of the encryption
You can also view the security details in your browser to confirm you have connected using 128-bit encryption.

Verify you are connected to the legitimate Westpac website
It is important for you to be certain that your browser has connected to the real Westpac Internet Banking site.

Every time you connect to Internet Banking, the service sends your browser a piece of information called a "digital certificate". This certificate securely identifies the site you are connecting to, and is used to establish the encrypted session. You can view the contents of the certificate when you first connect or at any other time that you connect.

For Microsoft Internet Explorer 5.01 and above, the certificate details can be obtained by double-clicking on the Internet Explorer data encrypted symbol displayed on the status bar.

For Netscape Navigator, click on the Netscape data encrypted symbol on the status bar and click the Page Info button.

This certificate has been "digitally signed" by Verisign, the most recognised issuer of digital certificates in the world. Most browser software is written to automatically recognise any certificate "signed" by Verisign.

Check the fields of the certificate. The Issuer field should contain a reference to Verisign. The Subject field should always show the organisation as Westpac Banking Corporation.

Each certificate also has a "digital fingerprint" which is essentially a string of numbers. Like any fingerprint, this fingerprint is unique, and you can verify the fingerprint displayed in the certificate, by contacting our Westpac Internet Helpline on 132 032.

If the fingerprint displayed in your browser does not match the fingerprint you have written down, you may have connected to an illegitimate site. Do not continue, and do not enter your customer number or password! To obtain assistance, contact 132 032.

For security purposes, Westpac will change its certificate at regular intervals. Likewise, you should regularly verify that the fingerprint displayed in your browser matches the fingerprint obtained, by contacting 132 032.

Important tips for Netscape users

Are you using Netscape Version 4.72 or below?
Netscape has advised that your browser has a vulnerability, which could allow secure data via an SSL connection to be intercepted.

Netscape suggest that you upgrade your browser to the latest version immediately.

What version of Netscape are you currently using?
To find out what browser version you are currently using, select the Help menu in your browser and then select the About option. Please note that this issue only effects customers using Netscape Navigator version 4.05 and below. If you are using Netscape Communicator 4.73 you will retain access to Internet Banking and you will not need to upgrade your browser.

Netscape Version 4.05
If you are using Netscape Version 4.05 and have not upgraded your browser since 31 December 1999 you will receive an additional Netscape security message box when attempting to access Internet Banking. This will advise that your browser certificate has expired. After clicking continue you will be redirected to a warning page on the Westpac website. You will be able to sign in from this page however you will continue to receive the Netscape security message box every 2 minutes whilst in a secure site. Netscape suggest that you upgrade your browser immediately to avoid this issue.
