What we are doing to protect you
We're committed to doing everything we can to keep your banking secure. We make
a considerable investment in establishing and maintaining the best possible systems
and processes to protect you.
Here are some of the measures we have in place:
OnlineCode – Two-factor Authentication
National Bank Online Banking customers can get double the protection with
OnlineCode. A unique code is sent to your mobile phone and must be entered
into Online Banking to authorise certain transactions. It provides an additional
layer of security, along with your customer number and password.
Education
Our Online Security Centre is one way we keep our customers informed about safe
online practices, and aware of different types of online fraud. We proactively work
with business and personal customers in a number of ways to keep them up-to-date
with new developments and reinforce ways they can protect themselves from online
fraud.
Transaction monitoring
The National Bank makes a considerable investment in sophisticated transaction monitoring
software to help identity potential fraud before it happens. The software identifies
potentially fraudulent or suspicious transactions and alerts bank staff so that
they can investigate and take action as required.
Extended Validation
Online Banking has an Extended Validation security certificate for your peace of mind.
This means that if you use either Internet Explorer 7 or Firefox 3 (or a later version)
the address bar will change colour to green in Online Banking, so you know you’re in the
genuine National Bank Online Banking system.
Bank Mail
Ordinary email is not a secure facility. You should never use it to send confidential
information, like bank account details, as others may be able to intercept it. That's
why we provide our Bank Mail option with Online Banking. Bank Mail
allows you to exchange confidential information about your account with us in a
secure environment.
Data encryption
All Online Banking sessions are secured using a 128-bit encrypted connection (using
Microsoft Server Gated Cryptography) between yourself and the Bank. This means that
the data travelling across the Internet, your computer and the Online Banking system
is encrypted, protecting your data from other people.
Online Banking time-outs
You should always ensure you sign out of Online Banking when you have finished using
it. However, if you forget, a session 'time-out' automatically logs you off the
system if there has been no activity for a certain period. This ensures no-one else
can see your Online Banking information.
Firewalls
We install and maintain up-to-date firewall technology to protect our systems from
unauthorised access via the Internet.
