FAQs - Online security

We take the security of your personal and account information seriously. That’s why we’ve got a range of security measures to ensure that your transactions and personal information are protected:

- Fraud detection system
We use sophisticated technology to monitor Internet Banking transactions and identify suspicious activity. Our Fraud Detection System looks for patterns of transactions and new behaviour which may indicate that a transaction is fraudulent. If we detect fraudulent activity, we’ll attempt to contact you and temporarily freeze your Internet Banking access in order to prevent further fraudulent transactions.
We will continue to enhance our Fraud Detection System and strengthen our monitoring processes.

Encryption is turning words and numbers into a coded language. Encryption prevents unauthorised users from being able to change or read your data. DWCB encrypts your personal data using 256-bit SSL (Secure Socket Layer) encryption technology. You can identify whether the Internet Banking session is secure or encrypted when you see https:// in the Address bar and/or when you see a padlock in the browser window. You can double click on the padlock to view the Digital Certificate i.e. the electronic signature to view details. 

Automatic time-outs
Within the DWCB Internet Banking system, your banking session can remain unattended for a maximum of 15 minutes. After this time, the system automatically 'logs off' and ends your session.
Remember, if you are not using your computer for a period of time, make sure you 'log out' completely from the DWCB Internet Banking system so that sensitive banking information cannot be viewed by others.

    • Keep passwords, PINs and any other security information secret including covering your card PIN when using ATMs, or Internet Banking in a public place. DWCB will never ask you to provide your PIN to an DWCB staff member.
    • Protect all your other personal information, including destroying your bank statements securely, collecting your mail promptly and not providing your details to anyone you do not trust.
    • Keep your computer safe by having up to date security software, checking you are only using trusted sites for purchasing items and not opening emails you’re not sure about.
    • Keep your computer browser (e.g. Internet Explorer, Firefox), and product software (Microsoft Office/Adobe flash, etc) up to date. Software providers frequently develop updates and patches to address new and developing security threats.
    • Report anything you are suspicious of immediately, especially if you think your card has been stolen, a suspicious transaction is on your bank statement, or your mail has been accessed by someone.

When using the Internet, including Internet Banking, always try to use hard-to-guess passwords.

Passwords will only keep outsiders out if they are difficult to guess! Don't share your password, and don't use the same password in more than one place. If someone should happen to guess one of your passwords, you don't want them to be able to use it in a number of places.

Remember the five golden rules of passwords.

    1. Do not choose a password that is easily identified with you (for example, your date of birth, telephone number or your name or any part of it).
    2. A password should have a minimum of eight characters, be as meaningless as possible and use uppercase letters, lowercase letters and numbers eg xk28LP97.
    3. Change passwords regularly, at least every 30 days.
    4. Do not give out your password to anyone! Be wary of unsolicited calls or emails requesting personal information or card numbers. Neither DWCB nor the police would ask you to disclose PIN’s or password information.
    5. Do not write your password down even if it is disguised.

Is your computer and information protected from viruses? Ensure your virus protection software is always up-to-date.

A computer virus is a program that attaches itself to another program, but changes the action of that program so that the virus is able to spread. Viruses range from harmless pranks that merely show an annoying message, to programs that can destroy or disable a computer altogether.

Anti-virus software is designed to better protect you and your computer against known viruses, worms and Trojan Horses. A Trojan Horse is a malicious program disguised as something harmless, such as a game or a screen saver, but in fact contains hidden code that allows an intruder to take control of your machine without your knowledge.

Being protected includes three things:

  1. Having protection on your computer.
  2. Checking for new Internet security protection software updates daily.
  3. Scanning all the files on your computer periodically including incoming and outgoing emails.

For more effective Internet protection, try using a firewall as a gatekeeper between your computer and the Internet.
A firewall is a piece of software or hardware that filters all Internet traffic between your computer and the outside world. It works to either block or permit Internet traffic to and from your computer. You can use the Firewall to better protect your home or business computer and any personal information it holds from offensive websites, spam and unauthenticated logins from potential hackers.

A Firewall is seen to be essential for those that use their computers online, especially through the use of a cable modem.

Is your computer security up-to-date? You should check your computer security on a regular basis and download the latest security upgrades.
Security is essential in protecting your information on the Internet. To do this, check your software vendors' web sites on a regular basis for new security upgrades, or use the automated patching features that some companies offer. The programs and operating system on your computer may have valuable features that make your life easier, but can also leave you vulnerable to hackers and viruses. You should evaluate your computer security on a regular basis.

Be cautious! Do not open email attachments from unknown sources.
Email is one of the prime movers for malicious viruses. Regardless of how enticing the 'subject' or attachment may look, be cautious. Any unexpected email, especially those with attachments (from someone you may or may not know), could contain a virus and may have been sent without that person's knowledge from an infected computer. Should you receive an email of this kind and you are doubtful of its legitimacy, delete it.

Make sure your family members and/or your employees know what to do if a computer becomes infected.
It's important that everyone who uses a computer is aware of proper security practices. People should know how to update virus protection software, how to download security upgrades from software vendors and how to create a proper password.
