Abstract: Present Web Security is a serious concern. We learn with great regularity that websites, databases, and online services become inaccessible due to denial of service attacks or display modified information on the user or organization. In other high-profile incidents, millions of passwords, email addresses, and credit card information were leaked into the public, exposing users to both personal humiliation and financial risk. Web security is designed to avoid these kinds of attacks. Web Security is characterized more formally by the act of ensuring websites from unauthorized access, usage, alteration, destruction, or disruption. The higher the protection, the more trust users put on the application. Security plays a key role in achieving success for the application, especially in Web services. This essay will therefore discuss how users use cryptography today, the encryption concepts for databases, and the encryption concepts for the security of online service, thus understanding the issue of web system security.
