How we keep your data safe

Online Teller security
Online Teller uses an integrated security system to protect your account data from exposure to unauthorized persons. This system is a three-tiered security policy that covers all aspects of your Online Teller service. These policies form a rigid security implementation that enables Members to conduct business with the Credit Union through the Internet with an extremely high degree of security.

Can anyone from the "outside" access the Credit Union's database?
At no time does anyone from the outside have access to the Credit Union's database via the Internet. Any and all requests for data must pass through two validation and control centers. Each request and answer is logged at each stop through the firewall (link to “What is a firewall?”). Additionally, any suspicious activity is logged and causes an alarm.

What is a firewall?
Firewalls are electronic barriers that shield your computer network from unnecessary and, in some cases, malicious Internet traffic. Mazuma is protected by firewalls, and it is recommended that you protect your personal computer with a firewall too. Firewalls are important for users who use Internet connections that are always turned on, such as cable and DSL modems. You can purchase firewalls at most computer and office supply stores.

What is encryption?
Encryption occurs for all information passing between you and Online Teller. Plainly stated, encryption is "mumbo jumbo." Encryption takes meaningful text and numbers and scrambles them into numerical nonsense before transmitting them across the Internet. This process uses complex mathematical formulas to create a key that is used to translate the "mumbo jumbo" nonsense back into meaningful data. There are billions of potential keys, and a different one is used for each session with Online Teller. The key to be used is established when the online connection is made between your computer and Online Teller. Each session uses a completely different key!

Your computer, as well as our computer system, recognizes the mathematical formulas of the encrypted messages during transactions. The more powerful computer system you have, the higher level or grade of encryption you can use.

128-bit encryption is a very secure form of encryption and is required for Online Teller.

How secure is my personal account?
Your personal account also has an additional two-layers of security surrounding it - your PIN (personal identification number) and your account number. Both are individual codes specific to your account only. Additionally, the Online Teller system will automatically lock access to your account should five unsuccessful attempts to access your account be made.
