TOKYO--October 26, 2009--Internet Initiative Japan Inc. (IIJ, NASDAQ: IIJI, TSE1: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced the addition of the new Attachment Encryption function as one of the measures to prevent information leaks on the IIJ Secure MX Service, a suite of functions that delivers strong security for corporate messaging environments.

The Attachment Encryption function automatically encrypts any attachment sent via email by users of the IIJ Secure MX Service. Information leaks via e-mail are said to occur most often due to misaddressed messages, and this new function helps to prevent information leaks for misaddressed messages that contain attachments.

Below is a list of service highlights.

Automatic encryption of file attachments

When an email message passes through the IIJ Secure MX Service Gateway, attachments are detected and automatically encrypted. These attachments are automatically converted to password-protected zip files, which removes the burden of encryption by employees and provides an easy and effective measure against information leaks via e-mail company wide. In addition, the function can be configured to encrypt all attachments or only those going to a specific addresses or domains, or only files with specific file name extensions, flexibly conforming to the corporate security policy.

Confirmation of the recipient's address and subject line prior to sending the password

Once an attachment is encrypted, a separate message is sent to the sender to confirm the recipient and subject. This confirmation message contains the password for decrypting the attachment as well as the recipient's address and subject line, allowing the sender to double check this information before the password is sent to the recipient.

Automatic time-lapsed transmission of passwords

In addition to manual transmission of the password information, the function can be configured to automatically notify the recipient of the password after a predetermined time (such as 10 minutes). This reduces the burden of approving each and every message. When the password information is automatically sent, a one-time URL for stopping the transmission is sent in the confirmation message, so if there is a problem, the sender can immediately cancel the distribution of the password.

The IIJ Secure MX Service has an existing suite of functions intended to help prevent information leaks via e-mail, such as the Online Storage (DOX) Integration function, which automatically moves file attachments to online storage, the Mail Audit function, which filters messages based on user-specified keywords or other conditions, and the Mail Archive function, for storing messages. The Attachment Encryption function can be used in combination with the other functions to provide strong measures against misaddressing.

IIJ will continue to expand the security features of the IIJ Secure MX Service to provide a more secure messaging environment.
