Monitor All International Transactions
Be aware of the differences between international and domestic transactions and pay special attention to all international transactions. Information passed with an international transaction (such as the format of a cardholder's address) differs from the information passed with a domestic transaction. Do everything you can to validate the order before you ship product to a different country.

Some Standard Computer Security Best Practices

Listed below are some standard computer industry security best practices.

Install a Firewall
Firewalls are special servers that monitor the activity of external connections, primarily the Internet, to an internal network of servers. Firewalls help to eliminate the threat of any undetected external activity, and safeguard your network and connections from outside vulnerabilities.

Store All Sensitive or Confidential Information Separate from Web Servers Customer information in particular, such as credit card numbers, should be stored in a secure database on a server that is not directly connected to the Internet. It is also a good idea to encrypt all stored information.

Use Good Anti-Virus Software and Update it Regularly. Anti-virus software is another important way to protect your network and computer systems from outside vulnerabilities. This software should be updated on a regular basis.

Regularly Download and Install Security Updates.For server and individual computer operating system software, you can optimize performance and systems protection by maintaining compatibility with service and security updates. Remember also to reinstall service and security updates when reinstalling software.

Avoid File Sharing
Share access to network drives and individual computers only with needed, trustworthy users. Especially avoid sharing access to files that store passwords and other confidential or sensitive information.

Security Best Practices
Avoid Idle Internet Connections
Disconnect when you are finished using the Internet. This may eliminate the possibility of undetected outside vulnerabilities. Also, it is a good practice to completely log out of any secure Web site, such as the Merchant Interface, or close the browser window if you will not be using the site for an extended period of time. Otherwise, in some cases, your login session may still be open.
