All of these items may be easy for the user to remember, but are also convenient for the average hacker. Another safeguard is to change passwords on a regular basis. For example, our group, along with Dr. Schwieger, chose the password in order to change information and to create items on the home page, but for safety reasons, Dr. Schwieger will want to choose a new password for future usage. More extreme control measures which businesses and others should be aware of are firewalls, filtering routers, encryption, and internal controls. Another control feature is that of cryptography.
Cryptography occurs when a message is written in a code and converted to regular text on the screen.
Cryptography guards personal information, or information that simply doesn't need to be shared with all Internet users. Although it may sound sad to be so security focused, everyone must be aware of hacker activity, and be prepared to guard against it. The best technique varies on the project and the level of security needed and should not be overlooked. This example uses JavaScript for verification control. The user must first enter their userid and two digit code.
