Online Banking Security

TBT Online Banking Security

Our Internet banking system uses industry-standard technology, including password-controlled entry, Secure Sockets Layer (SSL) protocol, data encryption, public/private key pair, firewalls, and filtering routers. Each security component acts as a layer of protection to safeguard sensitive data from unauthorized users.

Password-Controlled Access

First, the system will require your identification as a customer through a private account number and password before you can access the front-end of the system. You should keep your password and account number absolutely private.

Transmission Security: Encryption

Once you have logged on correctly, you will enter a secure environment from which you will conduct your transactions. The browser automatically secures the session using Secure Sockets Layer (SSL) protocol. With SSL, data that travels between the bank and customer is encrypted and can only be decrypted with what is called the "public and private key pair." As Netscape, the developers of the technology, put it, data that is encrypted with the public key can be decrypted only with the private key. Conversely, data encrypted with the private key can be decrypted only with the public key. This asymmetry is the property that makes public key cryptography so useful.

Information Privacy: Firewalls and Filtering Routers

Finally, once requests arrive at the bank, the server is protected by a series of firewalls and filtering routers which verify the source and destination of the requests traveling in information packets. The firewall is set up to reject any unauthorized traffic. This re-emphasizes the importance of the password, which provides the only legitimate entry into the program. The purpose of the router is to keep out traffic that does not emanate from one of the only two legitimate ends of a secured transaction: the customer or the bank.
