Restrict permission to confidential information in Office files using IRM

Among many new value added features of the Microsoft Office 2007, restriction the permission to use of many types of office documents is a notable one. You can restrict permission to content in documents, workbooks, and presentations by using Information Rights Management (IRM). For information on how you can restrict permission to content in e-mail messages, see Restrict permission to confidential information in e-mail messages in the help of your MS Office System. Most of the contents of this article is adapted from Microsoft Office Word 2007. For detail visit the help and support in the program.

For information on how to set a password to open or modify a file, see Set a password to open or modify a document, workbook, or presentation. There are other articles that describe using passwords to protect formatting in documents and protect worksheet or workbook elements.

The purpose of IRM and its limitations:
Information Rights Management (IRM) allows individuals and administrators to specify access permissions to documents, workbooks, and presentations. This helps prevent sensitive information from being printed, forwarded, or copied by unauthorized people. After permission for a file has been restricted by using IRM, the access and usage restrictions are enforced no matter where the information is, because the permission to a file is stored in the document 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 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

• Support file expiration so that content in documents 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 content and what level of editing is permitted for a document, workbook, or presentation. For example, a company administrator might define a rights template called "Company Confidential," which specifies that documents, workbooks, or presentations that use that policy can be opened only by people 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.

   • 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.

Alternatively, when you first try to open files that have been rights-managed by using IRM, the 2007 Office release 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 or search Google for more results.

Download permissions

The first time that you attempt to open a document, workbook, or presentation 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 document is not sent to the licensing server. For more information, read the Privacy Statement.

Restrict permission to content in files

Authors can restrict permission for documents, workbooks, and presentations on a per-user, per-document, or per-group basis (group-based permissions require Microsoft Active Directory directory service for group expansion). Authors use the Permission dialog box to give users Read and Change access, as well as to set expiration dates for content.

Remote Desktop overview

With Remote Desktop on Windows XP Professional, you can have access to a Windows session that is running on your computer when you are at another computer. This means, for example, that you can connect to your work computer from home and have access to all of your applications, files, and network resources as though you were in front of your computer at work. You can leave programs running at work and when you get home, you can see your desktop at work displayed on your home computer, with the same programs running.

When you connect to your computer at work, Remote Desktop automatically locks that computer so no one else can access your applications and files while you are gone. When you come back to your computer at work, you can unlock it by typing CTRL+ALT+DEL.

Remote Desktop also allows more than one user to have active sessions on a single computer. This means that multiple users can leave their applications running and preserve the state of their Windows session even while others are logged on.

With Fast User Switching, you can easily switch from one user to another on the same computer. For example, suppose you are working at home and have logged on to the computer at your office to update an expense report. While you are working, a family member needs to use your home computer to check for an important email message. You can disconnect Remote Desktop, allow the other user to log on and check mail, and then reconnect to the computer at your office, where you see the expense report exactly as you left it. Fast User Switching works on standalone computers and computers that are members of workgroups.

Remote Desktop enables a variety of scenarios, including:

• Working at home - Access work in progress on your office computer from home, including full access to all local and remote devices.
• Collaborating - Bring your desktop to a colleague's office to debug some code, update a Microsoft PowerPoint slide presentation, or proofread a document.
• Sharing a console - Allow multiple users to maintain separate program and configuration sessions on a single computer, such as at a teller station or a sales desk.

To use Remote Desktop, you need the following:

• A computer running Windows XP Professional ("remote" computer) with a connection to a Local Area Network or the Internet.
• A second computer ("home" computer) with access to the Local Area Network via network connection, modem, or Virtual Private Network (VPN) connection. This computer must have Remote Desktop Connection, formerly called the Terminal Services client, installed.
• Appropriate user accounts and permissions.

Use Word 2007 to open documents created in previous versions of Word

When you open a document in Microsoft Office Word 2007 that was created in Microsoft Office Word 2003, Word 2002, or Word 2000, Compatibility Mode is turned on, and you see Compatibility Mode in the title bar of the document window. Compatibility Mode ensures that no new or enhanced features in Office Word 2007 are available while you are working with a document, so that people who are using previous versions of Word will have full editing capabilities. Find this yourself at help center of MS Word 2007.

You can work in Compatibility Mode or you can convert your document to the Office Word 2007 file format. Converting your document allows you to access the new and enhanced features in Office Word 2007. However, people who are using previous versions of Word may be prevented from or have difficulty editing certain portions of the document that were created by using new or enhanced features in Office Word 2007.

Work in Compatibility Mode

When you open a Word 97–2003 document in Office Word 2007, Compatibility Mode is turned on, and you see Compatibility Mode in the title bar of the document window. In Compatibility Mode, you can open, edit, and save Word 97–2003 documents but you won't be able to use any of the new Office Word 2007 features.

Document elements that behave differently in Compatibility Mode

BIOS basics and advanced learning

http://www.quepublishing.com/

Main Menu
The standard CMOS Setup menu dates back to the 286 days, when the complete BIOS Setup consisted
of only one menu. In the standard menu, you can set the system clock and record hard disk and
floppy drive parameters and the basic video type. Newer BIOSes have more complicated setups with
more menus and submenus, so the main menu often is fairly sparse compared to older systems.
The main menu in a modern system reports system information such as the BIOS version, the processor
type and speed, the amount of memory, and whether the memory or cache is configured for ECC
functionality. The main menu also can be used to set the system date and time.

 

	Typical Main Menu Settings*
Feature	Options	Description
BIOS Version	No options	Displays the version of the BIOS
Processor Type	No options	Displays the processor type
Processor Speed	No options	Displays the processor speed
System Bus	No options	Displays the system bus frequency

Additional Advanced Features Settings
Setting	Description
Auto Configuration*	Selects predetermined optimal values of chipset parameters. When Disabled, chipset parameters revert to setup information stored in CMOS. Many fields in this screen are not available when Auto Configuration is Enabled.
EDO DRAM Speed Selection	The value in this field must correspond to the speed of the EDO DRAM installed in your system. This value is access speed, so a lower value means a faster
	system.
SDRAM RAS-to-CAS Delay*	This field lets you control the number of cycles between a row activate com-mand and a read or write command.
SDRAM RAS Precharge Time*	The precharge time is the number of cycles it takes for the RAS to accumulate its charge before DRAM refresh. If insufficient time is allowed, refresh might be incomplete, and the DRAM might fail to retain data.
SDRAM CAS Latency Time*	When synchronous DRAM is installed, you can control the number of cycles between when the SDRAMs sample a read command and when the controller samples read data from the SDRAMs.
SDRAM Precharge Control	When Enabled, all CPU cycles to SDRAM result in an All Banks Precharge command on the SDRAM interface.
DRAM Data Integrity Mode	Select Non-ECC or ECC (error correcting code) according to the type of installed DRAM. ECC allows for single-bit error correction and multibit error detection at a slight speed penalty to the system.
System BIOS Cacheable	Allows caching of the system BIOS ROM at F0000h–FFFFFh, resulting in better system performance. If any program writes to this memory area, a system error can result.
Video BIOS Cacheable	Allows caching of the video BIOS ROM at C0000h–C7FFFh, resulting in better video performance. If any program writes to this memory area, a system error can result.
Video RAM Cacheable*	Selecting Enabled allows caching of the video memory (RAM) at
(Video Memory Cache Mode)	A0000h–AFFFFh, resulting in better video performance. If any program writes to this memory area, a memory access error can result. Uncacheable Speculative Write-Combining (USWC) mode is the same as Enabled on some
	systems.
8/16 Bit I/O Recovery Time	The I/O recovery mechanism adds bus clock cycles between PCI-originated I/O cycles to the ISA bus. This delay takes place because the PCI bus is so much faster than the ISA bus.
Memory Hole at 15M–16M	Places a 1MB empty RAM area between 15MB and 16MB. Older software sometimes would not run with 16MB or more memory in the system; enabling this provides a workaround. This is normally not used.
Passive Release	When Enabled, CPU-to-PCI bus accesses are allowed during passive release. Otherwise, the arbiter accepts only another PCI master access to local DRAM.
Delayed Transaction	The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select Enabled to support compliance with PCI specification version 2.1.
AGP Aperture Size (MB)	Select the size of the accelerated graphics port (AGP) aperture. The aperture is a portion of the PCI memory address range dedicated for graphics memory address space. Host cycles that hit the aperture range are forwarded to the AGP without any translation.

CPU Warning Temperature	Select the combination of lower and upper limits for the CPU temperature if
	your computer contains an environmental monitoring system. If the CPU
	temperature extends beyond either limit, any warning mechanism programmed
	into your system is activated.
Current CPU Temperature	This field displays the current CPU temperature if your computer contains an
	environmental monitoring system.
Shutdown Temperature	Select the combination of lower and upper limits for the system shutdown
	temperature if your computer contains an environmental monitoring system. If
	the temperature extends beyond either limit, the system shuts down.
CPUFAN Turn On IN Win98	If you are running Windows 98, which supports ACPI, selecting Enabled gives
	the user a cooling choice at runtime. The user can run with the CPU fan turned
	on or off, depending on deciding factors such as CPU activity, battery power
	consumption, and noise tolerance.
Current System Temperature	This field displays the current system temperature if your computer contains a
	monitoring system.
Current CPUFAN 1/2/3 Speed	These fields display the current speed of up to three CPU fans if your computer
	contains a monitoring system.
IN0-IN6(V)	These fields display the current voltage of up to seven voltage input lines if your
	computer contains a monitoring system.
Spread Spectrum	When the system clock generator pulses, the extreme values of the pulse gener-
	ate excess EMI. Enabling pulse spectrum spread modulation changes the
	extreme values from spikes to flat curves, thus reducing EMI. This benefit in
	some cases might be outweighed by problems with timing-critical devices, such
	as a clock-sensitive SCSI device.

 

 

Legacy USB support means support for USB keyboards and mice. If you are using USB keyboards and
mice, you will find that the keyboard is not functional until a USB-aware operating system is loaded.
This can be a problem when running DOS, diagnostics software, or other applications that run outside
of USB-aware operating systems, such as Windows 98, Windows Me, Windows XP, and Windows
2000. In that case, you should enable the USB legacy support via this menu.
Even with legacy support disabled, the system still recognizes a USB keyboard and enables it to work
during the POST and BIOS Setup. With USB legacy support in the default (disabled) mode, the system
operates as follows:
1. When you power up the computer, USB legacy support is disabled.
2. POST begins.
3. USB legacy support is temporarily enabled by the BIOS. This enables you to use a USB keyboard
to enter the setup program or the Maintenance mode.
4. POST completes and disables USB legacy support (unless it was set to Enabled while in Setup).
5. The operating system loads. While the operating system is loading, USB keyboards and mice are
not recognized. After the operating system loads the USB drivers, the USB devices are recognized.
To install an operating system that supports USB, enable USB legacy support in BIOS Setup and follow
the operating system's installation instructions. After the operating system is installed and the USB
drivers are configured, USB legacy support is no longer used, and the operating system USB drivers
take over. However, I recommend that you leave legacy support enabled so the USB keyboard functions
in DOS while running self-booting or DOS-based diagnostics, or when running other
non–USB-aware operating systems.
Note that if USB legacy support is enabled, you shouldn't mix USB and PS/2 port keyboards and mice.
For example, don't use a PS/2 keyboard with a USB mouse or a USB keyboard and a PS/2 mouse. Also
remember that this legacy support is for keyboards and mice only; it won't work for USB hubs or
other USB devices. For devices other than keyboards or mice to work, you need a USB-aware operating
system with the appropriate USB drivers.

 

 

 

 

Security Menu
Most BIOSes include two passwords for security, called the supervisor and user passwords. These passwords
help control who is allowed to access the BIOS Setup program and who is allowed to boot the
computer. The supervisor password is also called a setup password because it controls access to the
setup program. The user password is also called a system password because it controls access to the
entire system.
If a supervisor password is set, a password prompt is displayed when an attempt is made to enter the
BIOS Setup menus. When entered correctly, the supervisor password gives unrestricted access to view
and change all the Setup options in the Setup program. If the supervisor password is not entered or is
entered incorrectly, access to view and change Setup options in the Setup program is restricted.
If the user password is set, the password prompt is displayed before the computer boots up. The password
must be entered correctly before the system is allowed to boot. Note that if only the supervisor
password is set, the computer boots without asking for a password because the supervisor password
controls access only to the BIOS Setup menus. If both passwords are set, the password prompt is displayed
at boot time, and either the user or the supervisor password can be entered to boot the computer.
In most systems, the password can be up to seven or eight characters long.
If you forget the password, most systems have a jumper on the board that allows all passwords to be
cleared. This means that for most systems, the password security also requires that the system case be
locked to prevent users from opening the cover and accessing the password-clear jumper. This jumper
is often not labeled on the board for security reasons, but it can be found in the motherboard or system
documentation.

 

Provided you know the password and can get into the BIOS Setup, a password can also be cleared by
entering the BIOS Setup and selecting the Clear Password function. If no Clear function is available,
you can still clear the password by selecting the Set Password function and pressing Enter (for no
password) at the prompts.

Plug and Play BIOS
Traditionally, installing and configuring devices in PCs has been a difficult process. During installation,
the user is faced with the task of configuring the new card by selecting the IRQ, I/O ports, and
DMA channel. In the past, users were required to move jumpers or set switches on the add-in cards to
control these settings. They needed to know exactly which resources were already in use so they could
find a set of resources that did not conflict with the devices already in the system. If a conflict exists,
the system might not boot and the device might fail or cause the conflicting hardware to fail.
PnP is technology designed to prevent configuration problems and provide users with the capability
to easily expand a PC. With PnP, the user simply plugs in the new card and the system configures it
automatically for proper operation.
PnP is composed of three principal components:
 Plug and Play BIOS
 Extended System Configuration Data (ESCD)
 Plug and Play operating system
The PnP BIOS initiates the configuration of the PnP cards during the boot-up process. If the cards previously
were installed, the BIOS reads the information from ESCD and initializes the cards and boots
the system. During the installation of new PnP cards, the BIOS consults the ESCD to determine which
system resources are available and needed for the add-in card. If the BIOS is capable of finding sufficient
available resources, it configures the card. However, if the BIOS is incapable of locating sufficient
available resources, the Plug and Play routines in the operating system complete the configuration
process. During the configuration process, the configuration registers (in flash BIOS) on the card and
the ESCD are updated with the new configuration data.
PnP Device IDs
All Plug and Play devices must contain a Plug and Play device ID to enable the operating system to
uniquely recognize the device so it can load the appropriate driver software. Each device manufacturer
is responsible for assigning the Plug and Play ID for each product and storing it in the hardware.
Each manufacturer of Plug and Play devices must be assigned an industry-unique, three-character vendor
ID. Then, the device manufacturer is responsible for assigning a unique product ID to each individual
product model. After an ID is assigned to a product model, it must not be assigned to any
other product model manufactured by the same company (that is, one that uses the same vendor ID).

 

 

BIOS Error Messages
When a PC system is first powered on, the system runs a POST. If errors are encountered during the
POST, you usually see a text error message displayed onscreen. Errors that occur very early in the
POST might happen before the video card is initialized. These types of errors can't be displayed, so the
system uses two other alternatives for communicating the error message. One is beeping—the system
beeps the speaker in a specific pattern that indicates which error has occurred.
The other alternative is to send a hexadecimal error code to I/O port address 80h, which can be read
by a special card in one of the bus slots. When the ROM BIOS is performing the POST, in most systems
the results of these tests are continuously sent to I/O Port 80h so they can be monitored by special
diagnostics cards called POST cards (see Figure 5.7). These tests sometimes are called manufacturing
tests because they were designed into the system for testing systems on the assembly line without a
video display attached.

 

The POST cards have a two-digit hexadecimal display used to report the number of the currently executing
test routine. Before executing each test, a hexadecimal numeric code is sent to the port, and
then the test is run. If the test fails and locks up the machine, the hexadecimal code of the last test
being executed remains on the card's display.
Many tests are executed in a system before the video display card is enabled, especially if the display
is EGA or VGA. Therefore, many errors can occur that would lock up the system before the system
could possibly display an error code through the video system. Because not all these errors generate
beep codes, to most normal troubleshooting procedures, a system with this type of problem (such as a
memory failure in Bank 0) would appear completely "dead." By using one of the commercially available
POST cards, however, you can often diagnose the problem.
These codes are completely BIOS dependent because the card does nothing but display the codes sent
to it. Some BIOSes have more detailed POST procedures and therefore send more informative codes.
POST cards can be purchased from JDR Microdevices or other sources and are available in both ISA
and PCI bus versions.
For simple but otherwise fatal errors that can't be displayed onscreen, most of the BIOS versions also
send audio codes that can be used to help diagnose such problems. The audio codes are similar to
POST codes, but they are read by listening to the speaker beep rather than by using a special card.

 

 

 

Remote Desktop overview

With Remote Desktop on Windows XP Professional, you can have access to a Windows session that is running on your computer when you are at another computer. This means, for example, that you can connect to your work computer from home and have access to all of your applications, files, and network resources as though you were in front of your computer at work. You can leave programs running at work and when you get home, you can see your desktop at work displayed on your home computer, with the same programs running.
When you connect to your computer at work, Remote Desktop automatically locks that computer so no one else can access your applications and files while you are gone. When you come back to your computer at work, you can unlock it by typing CTRL+ALT+DEL.
Remote Desktop also allows more than one user to have active sessions on a single computer. This means that multiple users can leave their applications running and preserve the state of their Windows session even while others are logged on.
