Security

We ensure your online transactions are safe and secure
At CBA, we use industry standard security technology and practices to safeguard your account from any unauthorized access.

We do this in the following ways:
Using log-ins and passwords to make sure we're dealing with you
Online access to your account is only possible once you have authenticated yourself using the correct Internet Banking ID and password.

Creating secure online sessions
When you log into Internet Banking you are said to be in a secure session. You know you are in a secure session if the URL address begins with https:// and a padlock symbol appears at the top of the page as part of the address bar.

Using encryption
Secure Sockets Layer (SSL) technology is used within your Internet Banking session to encrypt your personal information before it leaves your computer so that no one else can read it. Depending on your browser setting, a pop-up window will appear to notify you that you will be entering a secured page. We use 128-bit SSL encryption, which is accepted as the industry standard.

Using "layers" of security
CBA always does the following:

Ensure that all of our operating systems are updated with the latest security patches
Keep our anti-virus software updated
Use firewalls to prevent unauthorized intrusion

Using session timeouts
If you forget to log-off after banking online or your computer remains inactive for a period of time during a session, our systems automatically log you off. Pages viewed during a secure session are not recorded in your computer's temporary files.

Having automatic lock-outs
After a number of incorrect attempts to log in, we disable online access to your account. To re-activate your account, you should contact the CBA call centre.
