In the United States, banks employ several measures for security, including protecting against viruses with software, setting up firewalls, establishing cookies and encrypting data. Security measures vary among banks, but all take some precautions to ensure customers have safe online banking experiences. To ensure the highest level of security, banks use several methods of protection, say experts at Bank of America.
Banks control some aspects of secure online banking, such as establishing firewalls and keeping their computers protected with updated anti-virus software. However, users participate in the protection process too by selecting personal log in information and changing that information periodically.
Once selected, security measures safeguard users' accounts in several ways. One popular and effective method, Secure Socket Layer, or SSL, works on three levels to protect data, according to officials at Bank of America. When customers log in remotely, their computers connect with banks' servers. The servers then verify the identities of customers and their banks. If the banking system detects unusual or potentially fraudulent activity, computers disconnect from users' systems, preventing data transmission to unauthorized sources.
Cookies, another security tool, operate in a similar manner. They validate users' information when users log in, ensuring their authenticity. If cookies detect fraudulent activity, users must establish their identity using additional identifying information. Once set up with online banking, customers enjoy secure transactions domestically and even internationally.
