Online Security Statement
Earlham Savings Bank is pleased to offer internet banking services. Delivering these services requires a solid security framework that protects you and our institution's data from outside intrusion. We are committed to working with our internet service and communications providers to produce the safest operating environment possible for our customers.
There are several levels of security within our security framework. User level deals with cryptography and Secure Sockets Layer (SSL) protocol, and is the first line of defense used by all customers accessing our Banking Server from the public Internet. Server Level focuses on firewalls, filtering routers and our trusted operating system. Host level deals specifically with our internet banking services and the processing of secure financial transactions.
There are several components of User Level Security that insure the confidentiality of information sent across the public Internet. The first requires your use of a fully SSL-compliant 128 bit-encrypted browser such as Microsoft Internet Explorer or Mozilla Firefox. SSL is an open protocol that allows a user’s browser to establish a secure channel for communicating with our internet server. SSL utilizes highly effective cryptography techniques between your browser and our server to ensure that the information being passed is authentic, cannot be deciphered and has not been altered enroute. SSL also utilizes a digitally signed certificate, which ensures that you are truly communicating with the Online Banking Server and not a Third party trying to intercept the transaction.
After a secure connection has been established between your browser and our server, you then provide a valid User ID and Security Password to gain access to the services. You also establish Multi-Factor Authentication by choosing a Security Image, answering three Security Questions, and designating whether your log in is from a Personal (register the PC as a trusted source) or Public (do not register the PC as a trusted source) computer. This information is encrypted, logged by the server forming another complete physical security layer to protect the server’s information, and a request to log on the system is processed. If you do not register your PC or if a future online banking log in is made from a different PC you will be prompted to answer one of your chosen Security Questions to validate access.
Although SSL utilizes proven cryptography techniques, it is important to protect your User Access ID and Security Password from others. You must follow the Security Password parameters we specify at the time you sign-up for an internet banking account. We also recommend changing your Security Password often. Session time-outs and a limit on the number of logon attempts are examples of other security measures in place to ensure that inappropriate activity is prohibited at the user level. Invalid log in attempts are reviewed each business day by bank employees and followed up on appropriately.
All transactions sent to our Banking Server must first pass through a filtering router system. These filtering routers automatically direct the request to the appropriate server after ensuring the access type is through a secure browser and nothing else. The routers verify the source and destination of each network packet and manage the authorization process of letting packets through. The filtering routers also prohibit all other types of Internet access methods at this point. This process blocks all non-secured activity and defends against inappropriate access to the server.
The Banking Server is protected using the latest firewall platform. This platform defends against system intrusions and effectively isolates all but approved customer financial requests. The platform secures the hardware running the on-line applications and prevents associated attacks against all systems connected to the Banking Server. The system is monitored 24 hours a day, seven days a week for a wide range of anomalies to determine if attempts are being made to breach our security framework. In addition, intrusion tests are conducted at least annually by independent third parties to validate and measure the effectiveness of Banking Server security.
Once authorized, the customer is allowed to process authorized internet banking transactions using host data. In addition, communication time-outs ensure that the request is received, processed and delivered within a given timeframe. Any outside attempt to delay or alter the process will fail. Further password encryption techniques are implemented at the host level, as well as additional security logging and another complete physical security layer to protect the host information itself.
When you follow these security measures, your interaction with online banking will be completely confidential.
