To help your business stay safe online, NAB’s Security team is sharing our top cyber security tips.

It’s really important that you have the right security measures in place to protect your business from disruption, the loss of information, or even theft.

There are some simple steps you can take to reduce the risk of becoming a target for cyber criminals.

Here is our advice to help you stay safe online:

1. Make sure your systems are secure by:

  • Having up-to-date anti-virus software installed on all computers
  • Taking advantage of NAB’s free six month anti-virus offer for customers
  • Ensuring automatic updates are enabled for your operating system and programs, so they receive important security upgrades
  • Remove administration rights from computers that don’t need it

2. Protect your business data by:

  • Regularly backing up data, storing it offsite; and testing the backups regularly.

3. Be vigilant on passwords and access management by:

  • Using strong passwords with letters, numbers and symbols
  • Using a different password for each of your accounts
  • Ensuring each employee has their own login credentials to business systems
  • Using different computers to create and approve transactions

4. Speak to your banker about adding extra layers of security when using NAB Connect. The following controls will reduce the risk of human error and unauthorised transactions occurring:

  • Segregation of duties - this enforces the need for a transaction to be created and approved by separate people in your business.
  • Dual authorisation - each transaction must be approved by two (or more) people in your business.
  • A security token – provides each NAB Connect user in your business with unique one-time passwords for logging in, creating and approving transactions.

5. Be on the lookout for suspicious emails with these features:

  • Sent from an unknown sender
  • Contains links or attachments
  • Generically addressed (e.g. Dear valued customer…)
  • Containing unsolicited or irrelevant content
  • Spelling or grammatical errors
  • Sense of urgency

If you receive a suspicious email, report it to without clicking on any links or attachments.

You can see the latest phishing emails on the Latest Security Alerts page on

If you believe your account has been compromised, or notice anything unusual:

  • Do not proceed with any transactions
  • Immediately contact the NAB Connect Client Centre on 1300 888 413 (option 1) and advise your computer may be infected with malicious software
