Protecting your NetTeller account information is as important to us as it is to you. That is why the following controls have been put into place.

SSL Protocol
NetTeller access requires you to use a browser that uses SSL protocol. SSL stands for Secure Socket Layer, which lets one computer verify another’s identity to allow secure connections.

128 Bit Encryption
To ensure the highest level of security, we require that all users have browsers that support 128 bit encryption. We use the latest encoding technology to ensure that your private information cannot be intercepted. Encryption is a way to rewrite something in code, which can be decoded later with the right “key.” When you request information about your accounts, the request is sent encrypted to UNION Savings BANK. We decode your request and send the requested information back to you in an encrypted format. When you receive the information, it is decoded so that you can read it.

Firewalls
A Firewall is a specially programmed computer that connects a local network to the Internet and, for security reasons, lets only certain kinds of messages in and out.
PIN Security System – To keep unauthorized individuals from accessing your account by guessing your PIN, we have instituted a PIN security system. If your PIN is entered incorrectly three consecutive times, the user is “locked out” of the system. You must contact the bank for your account to be reset and the system to be unlocked.

Automatic Log-Off
If you are logged on to NetTeller but do not perform any activity for 10 minutes, you will not be able to proceed until you “re-log” on to the system.

Pseudo Names
We do not display account numbers over the Internet. Instead, we allow you to choose a “pseudo name” for each of your accounts. These pseudo names overwrite your account number so you have easy recognition of your accounts. For example, Household checking, Judys savings, etc.

Keeping Your Account Information Secure
While NetTeller strives to maintain the highest level of security, your account privacy depends largely on you. Here are several things you can do to keep your account information secure.

• Don’t reveal your User ID or PIN to anyone else. Your User ID and PIN are designed to protect your banking information, but they will only work if you keep them to yourself.
• Avoid selecting codes based on personal information or dictionary words.
• Avoid keeping written records of your codes.
• Keep your PIN number confidential and change it frequently to ensure confidentiality.
• Don’t walk away from your computer if you are in the middle of a NetTeller session.
• Once you have finished your NetTeller session, sign off before visiting other Internet sites.
• Do not change your “pseudo name” for your NetTeller accounts to your actual account numbers.
• If you notice any suspicious or unusual activity related to any of your accounts, contact the NetTeller manager immediately at 1-815-235-0800 or e-mail us at custservice@unionsb.com.
