Restrict permission to confidential information in e-mail messages

The purpose of IRM and its limitations

Information Rights Management (IRM) allows individuals to specify access permissions to e-mail messages. This helps prevent sensitive information from being printed, forwarded, or copied by unauthorized people. After permission for a message has been restricted by using IRM, the access and usage restrictions are enforced no matter where the information is, because the permissions to access an e-mail message are stored in the message file itself.

IRM helps individuals enforce their personal preferences concerning the transmission of personal or private information. IRM also helps organizations enforce corporate policy governing the control and dissemination of confidential or proprietary information.

IRM helps to do the following:

  • Prevent an authorized recipient of restricted content from forwarding, copying, modifying, printing, faxing, or cutting and pasting the content for unauthorized use
  • Prevent restricted content from being copied by using the Print Screen feature in Microsoft Windows
  • Restrict content wherever it is sent
  • Provide the same level of restriction to e-mail attachments, as long as the attachments are files created by using other Microsoft Office programs, such as Microsoft Office Word 2007, Microsoft Office Excel 2007, or Microsoft Office PowerPoint 2007
  • Support file expiration so that content in documents and e-mail messages can no longer be viewed after a specified period of time
  • Enforce corporate policies that govern the use and dissemination of content within the company

IRM can't prevent the following:

  • Content from being erased, stolen, or captured and transmitted by malicious programs such as Trojan horses, keystroke loggers, and certain types of spyware
  • Content from being lost or corrupted because of the actions of computer viruses
  • Restricted content from being hand-copied or retyped from a display on a recipient's screen
  • A recipient from taking a digital photograph of the restricted content displayed on a screen
  • Restricted content from being copied by using third-party screen-capture programs

Configure your computer to use IRM

To use IRM in the 2007 Office release, the minimum required software is Windows Rights Management Services (RMS) Client Service Pack 1 (SP1), which can be installed on your computer either by you or your RMS administrator. The RMS administrator can configure company-specific IRM policies that define who can access information and what level of editing is permitted for an e-mail message. For example, a company administrator might define a rights template called "Company Confidential," which specifies that an e-mail message that uses that policy can be opened only by users inside the company domain.

Install the Windows Rights Management Services (RMS) Client

  1. In Microsoft Windows, click the Start button, and then click Control Panel.
  2. Do one of the following:
    • Microsoft Windows Vista  Click Programs, and then under Installed Programs, click Install a program from the network. In the list of programs, click Windows Rights Management Services Client, and then click Add.

       Note    In Classic view, double-click Programs, and then click Get programs. From the list of programs, click Windows Rights Management Services Client, and then click Add.

    • Microsoft Windows XP  Click Add or Remove Programs, and then click Add or Remove Programs. In the left pane, click Add New Programs. From the list of programs, click Windows Rights Management Services Client, and then click Add.

       Note    In Classic view, double-click Add or Remove Programs, and then in the left pane, click Add New Programs. From the list of programs, click Windows Rights Management Services Client, and then click Add.

Alternatively, when you first try to open e-mail messages that have been rights-managed by using IRM, Office Outlook 2007 prompts you to download the Windows Rights Management Services Client. For more information about the Windows Rights Management Services Client, visit the Windows Rights Management Services Web site.

Download permissions

The first time that you attempt to open an e-mail message with restricted permission, you must connect to a licensing server to verify your credentials and to download a use license. The use license defines the level of access that you have to a file. This process is required for each file with restricted permission. In other words, content with restricted permission cannot be opened without a use license. Downloading permissions requires that Microsoft Office send your credentials (which includes your e-mail address) and information about your permission rights to the licensing server. Information contained in the e-mail message is not sent to the licensing server. For more information, read the Privacy Statement.

Send an e-mail message with restricted permission

  1. Start Outlook, and then open a new message.
  2. Click the Microsoft Office Button , and then click Permission.

    To use a custom permission policy (permission policy: An approach to restricting permission for a given document, workbook, presentation, or message. The policy defines which Office features are available, which information can be accessed, and what level of editing is allowed.) that an e-mail administrator has created for people in your company, click the arrow next to Permission, and then click a custom permission policy on the menu.

  3. The InfoBar of the new message displays Do Not Forward, indicating that the message is rights-managed. This means that recipients cannot forward, print, or copy the message content. Only the person initiating the message, known as the conversation owner, has no restrictions.

  4. Address and send the message.

    Each recipient will be able to view additional content when replies are sent by anyone on the conversation thread.

Tip  You can also restrict permission to a new message by doing the following: In the new message, on the Message tab, in the Options group, click Permission .

 Notes 

  • If you attach a document, workbook, or presentation to a message with restricted permission, Office Outlook 2007 automatically applies the same restricted permissions to the attachment.
  • If the attached document, workbook, or presentation has already been rights-managed in its originating program, such as Office Word 2007, Office Excel 2007, or Office PowerPoint 2007, those permissions remain in effect.

Set an expiration date for a message

Even though it is not an IRM feature in Office Outlook 2007, you might want to set an expiration date for the new message so that its content can no longer be viewed after a specified period of time.

  1. In the new message, on the Message tab, in the Options group, click the Options Dialog Box Launcher .
  2. In the Message Options dialog box, under Delivery options, select the Expires after check box, and then select a date and time.

Use a different Windows user account to rights-manage e-mail messages

  1. Open the message.
  2. Click the Microsoft Office Button , click the arrow next to Permission, and then click Manage Credentials.
  3. In the Select User dialog box, do one of the following:
    • Select the e-mail address for the account you want to use, and then click OK.
    • Click Add, type your credentials for the new account, and then click OK twice.

View messages with restricted permission in Outlook

Messages with restricted permission that you receive can be identified by the following icon, which appears next to the message in the message list of your Inbox.

If you attempt to open and view a message with restricted permission without first obtaining a certificate, Outlook gives you the option to obtain one. After the certificate is installed, you can view the contents of the message by opening the message.

 Note    You cannot view the contents of a rights-managed message in the Reading Pane.

 Note    If the recipient replies to the message, only the sender who restricted the message, also known as the conversation owner, has full permission to the reply content. In other words, replies have the same restrictions to recipients as the original message.

If you need to read or open content with restricted permission but the 2007 Office release is not available on the computer that you are using, you can download the Rights Management Add-on for Microsoft Windows Internet Explorer, which enables you to view the messages in Internet Explorer. With this add-on, recipients can only view messages. Recipients cannot reply to, forward, copy, or print the messages.

 Note    When using the Rights Management Add-on to view messages, attachments that might have been sent with the message cannot be viewed.

Modem Features and Types

Modem Feature

Benefit

Who Should Buy

Cautions

MNP10EC support

Improves performance on poor-quality phone lines by quickly adjusting line speed up and down with changing conditions.

Anyone with poor-quality lines, especially if modem at other end also has MNP10EC support; users who want to use modem with cellular phones.

Don't buy MNP10 support by mistake; MNP10EC is much better and includes MNP10. Check with ISP to see whether cellular connections are supported; speed of such connections can be 14.4Kbps or slower.

PCI bus

Works in PCI slots that dominate current systems and have replaced ISA slots. PCI modems can share IRQs with other devices and be redirected to open IRQs.

Anyone without ISA slots or who is planning to move the modem to another computer in the future and prefers internal modems.

Verify one or more PCI slots are available; look for other features listed here to make change as useful as possible.

USB connection

Works with USB connectors on most current and all future computers; high-speed connection and capability to connect many devices via a hub.

Anyone who wants portability and has USB connectors along with Windows 98 or above.

Although Windows 95 OSR 2.5 (Win95"C") has USB support, many devices require Win98 or better; make sure USB ports have been activated in BIOS.

Gaming-optimized modem

Faster PING and response for gaming, which is more important than data throughput.

Anyone who plays a lot of online games or wants to get started.

Game optimizations are not useful for ordinary Web surfing. These modems are more expensive than others.

Call-waiting support

Allows you to answer the phone and not lose modem connection, instead of disabling call waiting, which most modems require.

Anyone who uses call waiting and doesn't like voice callers to get busy signals; check with manufacturer to see whether your existing modem can be upgraded with a driver.

Maximum talk time might be only a few seconds; make sure you have the phone near the computer for fast "hello, I'll call you later" answers to avoid exceeding time limit.

V.92/V.44 support

Faster uploads, faster connection negotiation, Modem-on-hold, better throughput on downloads.

Anyone whose ISP supports all V.92/V.44 features.

Check with your ISP to see when V.92/V.44 support will be introduced and to see whether all features will be supported.

Voice support

Allows digitizing of received calls; computerized answering machine and faxback; inbound and outbound phone calls via computer.

Anyone who wants to use PC as a telecommunications center.

Check quality of voice recording; can use up a lot of disk space.

 
Adapted from 12th edition of Que, Upgrading and Repairing PCs

Can Non-56Kbps Modems Achieve Throughput Speeds Above 115,200bps?

Yes. To achieve speeds above 115,200bps, a better UART chip than the standard 16550-series chip found in modern PC serial ports and internal modems is required. 16650 UARTs have a 32-byte buffer, as opposed to the 16-byte buffer found in the standard 16550 UART. The 16650 is seldom used in PCs' built-in serial ports or as part of an internal modem, but it can be added by installing a high-speed serial port interface card (which might require you to disable your current COM ports).

Thus, to achieve the highest possible speeds, you need the following: an external modem capable of running at 230.4Kbps throughput, a 16650 UART chip in the serial (COM) port connected to the modem, and appropriate software drivers for the modem. Note that a 56Kbps-compatible modem isn't required! 230.4Kbps connections are available with anything from V.34bis to ISDN modems if the device is designed for that speed and you have the correct UART chip and drivers. But, as with the lower-speed throughput rates mentioned earlier, these speeds apply only to data that has not been compressed already.
 
External modems connected to the USB port instead of a serial port are capable of speeds above 115,200bps because of the faster throughput of the USB port. If  possible, use the USB port rather than the serial port if you need to connect an external modem to your computer.

Add Rename and/or Delete to special folders

I have given my concentration to make these codes accurate as far as I know. While using these resources, you're responsible for any damages caused to your system. However, you can notify me of any confusions/errors occurred by the use of any of these codes. Simply, make a comment the this geek blog posting.
 
You can add a Rename or Delete command or both to the right-click menu for special folders like My Computer, My Documents and so on if you know the GUID (Globally Unique ID) for that folder. Just navigate to HICEY_CLASSES_ROOT\CLSID\{GUID}\ShellFolder and add or modify a Binary Attributes value (New > Binary value) to change the setting. In place of {GUID}, use one of these:

DOS Command Reference

Even if the systems you support, upgrade, and repair are all running the latest version of Windows, you will inevitably find yourself occasionally troubleshooting these systems from the DOS command line. This is partial adaptation from Upgrading and Repairing PCs, 12th Edition by Que.
 
This blog post tends to provide you with all the basic essentials that a programmer need to know. Though this is an age of visual programming, I think the commands presented here may help you as they're doing to me. [Project : Basic Commands]
