With banking business increasingly being conducted on the Internet, many questions have come up about security. Through Cryptographic Technology, information is protected by scrambling the data as it is transmitted across the Internet. Plattsmouth State Bank uses 128-bit encryption, the highest form of encryption, reserved primarily for financial institutions. There are two levels of encryption: 40-bit and 128-bit. With 40-bit encryption, there are billions of possible keys to decipher the coded information, and only one of them works. Someone intercepting the information would have to find the right key - a nearly impossible task. With 128-bit encryption, there are 300 billion trillion times as many keys as with 40-bit encryption. It is virtually impossible for an unauthorized party to find the right key, even if they are equipped with the best computers. Other security tools are available to ensure the integrity of your data; firewalls and filtering routers are used to secure computers from Internet access and a "trusted" operating system is employed to protect the information from both internal and external threats. For added security, customers are required to determine their own password. "Password guessing" is deterred by locking a user out of the system following three unsuccessful attempts. These are just some of the Internet security tools we use. These layers of security work together to make sure that all information transmitted between you and the bank is both secure and authentic.
