Internet Security Information

First Security Bank's Internet Banking system is part of the Computer Services, Inc. (CSI) Network that utilizes a comprehensive security strategy to protect your accounts and transactions conducted over the Internet. In-depth information on many of the techniques and features employed by the system can be viewed or printed from our website where the system's consumer or commercial features are explained under the link for "ID Theft".

We provide a number of additional security features in online banking. Online banking will "timeout" after a specified period of inactivity. This prevents curious persons from continuing your home banking session in case you have left your PC unattended without logging out. You may set the timeout period in the User Options screen of online banking. However, we recommend that you always sign-off (log out) when you are done with your online banking. The network architecture used to provide the online banking service was designed by the brightest minds in network technology. While the architecture is too complex to explain here, it is important to point out that the computers that store your actual account information are not hooked up to the Internet. The requests you make through the Internet are handled by our home banking servers, which retrieve the information you requested from our mainframe via proxy-based firewall servers. These servers act as the go-between between you and our mainframe computers.

It is also important to verify that only authorized persons log into home banking. This is achieved by verifying your password. When you submit your password, it is compared with the password we have stored in our secure data center. We allow you to enter your password incorrectly five (5) times. If you enter your password incorrectly five times, your online banking account will be locked until you call us to reinitialize the account. We monitor and record "bad-login" attempts to detect any suspicious activity (i.e., someone trying to guess your password). You play a crucial role in preventing others from logging on to your account. Never use passwords that are easy to guess. Examples of bad passwords are: Birth dates, first names, pet names, addresses, phone numbers, social security numbers, etc. Never reveal your password to another person. You should periodically change your password in the Settings screen of online banking.

As the number of possible combinations grows, it becomes less likely that anyone would be able to guess the combination in order to decrypt the message. Today's browsers offer 128-bit encryption. To get the number of possible combinations in 128-bit encryption, multiply "2" by itself 128 times (enter "2^128" on a calculator). 128-bit encryption has over 34,000,000,000,000,000,000,000,000,000,000,000,000 (34 followed by 36 zeros) combinations. Using a computer that does one billion calculations per second, it would take a hacker over one-sextillion years (10 followed by 21 zeros) to crack a 128-bit encryption key.

If you have more questions about our security systems for conducting transactions safely over First Security Bank's Internet Banking, contact our Internet Banking Department at 972-539-1849 or e-mail

Registration Process

The First Security Bank's Internet Banking service requires that the customer complete the initial registration process. This involves completing a secure online application that will identify your First Security Bank location and all the information that we will need to enable the service. The Internet Banking Department will verify the information you submitted for accuracy and authorizations. In about 2 or 3 days, you will be notified when your account will be activated.

Log-On Security

Security is very important to First Security Bank's Internet Banking. At the time you request the service, you will select a unique Username that will be used to gain access to the system. Prior to activation, the Internet Banking Department will verify your identity and authorization to information associated with the accounts that you requested tied to the service. Once your request has been authorized, the bank will issue you a security code to be entered the first time you access your account only. After that, you will only be required to choose a password that meets the “complex” criteria given. You will also choose a security image and phrase and will be required to choose and answer 3 challenge questions for further identification and security. You will also be emailed a one-time link to complete the initial setup.

To help prevent unauthorized access and ensure the security of your accounts, your online session will require you to log in again if no activity is detected for 15 minutes. This is to protect you in case you accidentally leave your computer unattended after you logged on.

Because your password is used to access your accounts, you should treat it as you would any other sensitive personal data. You should carefully select a password that is hard to guess. Keep your password safe. Memorize your password and never tell it to anyone. You may consider changing your password occasionally, such as every 90 days. This can be done at any time after you logged on from the "settings" tab.


You may request to access any account on which you are a signer or owner. If you desire services that allow you to initiate payments or transfers from the account, you will need the required withdrawal authority over the account to be able to complete the transaction. By using the service, you agree to maintain one or more accounts with us and to keep sufficient balances in any account to cover any transaction and fees that are ultimately approved by or related to the system. If the accounts added to the service are jointly held or have multiple signers, you agree that access to the information and all transactions initiated by the use of your Access Code and Password are authorized unless we have been notified to cancel the service.

Fees for First Security Bank's Internet Banking

The First Security Bank's Internet Banking service is available to our existing personal account customers at no monthly charge. The Bill Payment feature is free of charge.

Cancellation of First Security Bank's Internet Banking

Your First Security Bank's Internet Banking may be canceled at any time by First Security Bank in whole or part without prior notice due to insufficient funds in one of your accounts or other circumstances that may create an unanticipated liability to us. You will remain responsible for all transactions approved by the system prior to the cancellation, and for any other fees associated with the service. After cancellation, service may be reinstated once sufficient funds are available in your accounts to cover any fees and other pending transfers or debits. In order to reinstate services, you must call First Security Bank's Customer Service at 972-539-1849.

Balance Inquiries, Bill payments and Transfers Limitations

You may use First Security Bank's Internet Banking to check the balance of your accounts and to transfer funds among your accounts. According to Federal regulations, you may not make more than six (6) pre-authorized or automatic transfers or bill payments from your Money Market Savings Account during a given monthly statement period. There are no limits to the number of transfers or bill payments from your CHECKING ACCOUNTS. First Security Bank currently limits the bill-payment service to only Checking Accounts.

Balances shown in your accounts may include deposits subject to verification by us. The balance may also differ from your records due to deposits in progress, outstanding checks or other withdrawals, payments or charges. A transfer request may not result in immediate availability because of the time required to process the request. If you have further questions, contact your Internet Banking Coordinator.

The balances are updated periodically and the system will display the most current "as of" date on the "accounts" summary page. There may be situations that cause a delay in an update of your balances. The system will use the most current balance available at the time of a transaction to base our approval.

Special Information about the Stop Payment, Check Reorders, Address Change, Order Documents, Secure E-Mail & Secure File Delivery Services

The system includes several options under the "support" tab that provide a means to securely forward your request to us for processing. Generally, requests received from the system will be processed within one business day using procedures that would handle similar requests received by mail or fax. If urgent action is required, we recommend that you contact First Security Bank directly by telephone or in person. There may be additional fees associated with some of these services. If you have a problem or need to cancel a bill payment, you will need to contact the First Security Bank's Internet Banking Internet Department.

Bill Payment Service

It is easy to pay bills online. Simply set up your Payees by choosing from the database of vendors (Payees) that already exist, or by entering necessary information to schedule a payment. We are able to process payments to payees that have a U.S. Postal address. We maintain a large vendor database of regional or national billers to make this process quicker and easier. The Bill Payment service will also allow you to see a history of all the payments made from your accounts.

The daily limit for the total dollars of payments approved is governed by the system's available balance in the checking account selected for making the payment. You can withdraw up to the system's available balance as long as your account shows sufficient funds to cover your payments. The payment will normally be charged to your account on the business date that it is approved.

There is no monthly fee for the Bill Payment service.

If for any reason a scheduled payment processed through the system is declined, it will automatically be rescheduled for the following business day. The system will notify you of this action by sending you a "message" that will appear the next time you log on to the system. The system will continue to attempt to pay the bill on the following business days until there are sufficient funds or you cancel or reschedule it.

Although payments may be scheduled for the current business day or any date in the future at any time, they will only be processed once a day at our cut-off time, usually around 3:00PM CST on any business day. (If you attempt to schedule a payment for that day after 3:00PM, the system will notify you that you need to change the date to the next business day.) Anything scheduled on a non-business day, or after the cut-off time, will not be sent out until the following business day. Since we must forward the funds and billing information to the payee, some lead-time for payments is necessary. In general, the system will attempt to tell you when you can expect the payment to be received by the payee. Any delays caused by the payee/vendor would result in additional days before the payment would show on their records. By using this service, you authorize us, and any third-party payment-processing agent we may use, to choose whatever method we feel is the most effective method to process your transaction.

The time frames generally will be determined by the way the payment is sent to the payee. If we have to send a paper check in the U.S. Postal system, we typically suggest sufficient time as five (5) business days prior to the payee receiving the payment for processing at their address. If the payee accepts the payment electronically, we generally define sufficient time as two (2) business days prior to the payee receiving the payment. In all cases, the payment will be delivered to the payee/vendor by the tenth business day after the payment was approved and charged to your account.

Our Liability for Incomplete Transactions

It is our responsibility to process all bill payments properly initiated through First Security Bank's Internet Banking system in accordance with the Agreement. We will be liable for damages, as defined in the Agreement, where the system caused a payment delay or failed to process a payment to be received by the payee/vendor by the tenth business day following the date your account was charged for the payment. Transfers will be processed within two business days of the completed transfer transaction. We will not be liable if any of the following occurs:

  • Funds are not showing on the system's available balance in your account that is to pay for the bill or transfer at the time of the transaction.
  • Funds are subject to legal process or other encumbrances restricting the payment or transfer.
  • You had knowledge of or questions about the possible malfunction of the system when you initiated the transaction.
  • Any information provided by you about the Payee is incorrect.
  • There are any delays in the handling of the payment by the Payees.
  • Natural disasters (fire, flood, tornado, etc.) or other uncontrollable circumstances (mail delays, power failures, etc.) prevent proper completion and delivery of transactions.
  • Other applicable laws and/or regulations exempt us from liability.
  • It can be shown that the merchant or payee received the payment within the normal delivery timeframe and failed to process the payment through no fault of First Security Bank's Internet Banking or our service providers.
  • It can be shown that the delay was caused by unusual mailing delays by the U.S. Post Office.

We will reimburse you up to $50 per payment for any late payment fees or penalties you are charged as a result of the Payee/Vendor not receiving a payment by the Due Date if all the following apply:

  • You scheduled the payment before the cut-off time on a transaction date at least ten (10) business day prior to the Due Date.
  • Correct information was provided to us about the Payee (name, address, account number, and amount).
  • Your account contained sufficient available funds to complete the payment or transaction on the transaction date.
  • The Payee was a Business Payee that charges late charges or penalties.
  • Late payment fees or penalties were assessed by the Payee due to the delay of this payment.
  • You received no prior notice from the Payee/Vendor that there was a problem with processing payments from our system.
  • You received no notice within the ten (10) business day period that would have allowed you to alert our First Security Bank's Internet Banking Internet Department of a problem where we could have taken corrective action to remedy the situation prior to the tenth day.

Notice of Your Rights and Liabilities

Notify us immediately if your Username and Password have been compromised, lost, stolen or used without your authorization. Failure to notify us immediately could result in the loss of all money accessible by the Password. Telephoning us at the number listed below in the Contact Us section is the best way of limiting your possible loss. You could lose all the money in your account (plus your maximum overdraft line of credit, if you have one).

If we are notified within two (2) business days after you discover that your Username and Password have been compromised, lost or stolen, you can lose no more than $50.00 if someone used it without your permission. If you do not notify us within two (2) business days, and we can prove we could have prevented someone from using the Username and Password without your permission, you could lose as much as $500.00

If your statement shows unauthorized transfers, notify us within 60 days after the statement is mailed to you or viewed on your computer. After 60 days, if we can prove that we could have stopped someone from taking the money if we had been told, you may not get back any money from us. If a good reason, (such as a long trip or hospital stay) kept you from telling us, we may extend the time periods to a reasonable time.
