Disabling AutoRun

Another method of hardware security is to disable the AutoRun feature of the operating system. AutoRun automatically follows the instructions in a special file called autorun.inf when it is found on new media. AutoPlay is different from AutoRun. The AutoPlay feature is a convenient way to automatically identify when new media, such as optical disks, external hard drives, or thumb drives, are inserted or connected to the computer. AutoPlay prompts the user to choose an action based on the content of the new media, such as run a program, play music, or explore the media.

On Windows, AutoRun is executed first, unless it is disabled. If AutoRun is not disabled, it follows the instructions in the autorun.inf file. On Windows Vista and Windows 7, AutoRun is not allowed to bypass AutoPlay. However, on Windows XP, AutoRun bypasses AutoPlay and might launch an application without prompting the user. This is a security risk because it can automatically run a malicious program and compromise the system, so it is recommended to disable AutoRun.

To disable AutoRun in Windows XP, follow these steps:

Step 1. Select Start > Run.

Step 2. Type regedit and click OK.

Step 3. Navigate toHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdrom.

Step 4. Double-click AutoRun. In the Value Data text box, type 0 and click OK, as shown in Figure 1.

Step 5. Close the Registry Editor.

Step 6. You might have to log out and then log back in for this change to take effect.

Protecting Data While in Use

For users that need to access sensitive network resources, a token can be used to provide two-factor authentication. A token can be hardware type, such as a pin card,  or a software type, such as a soft token program, . The token is assigned to a computer and creates a unique code at certain times. When users access a network resource, they enter a PIN and a number displayed by the token. The number displayed by the token is created from a calculation made with its internal clock and a random number encoded on the token at the factory. This number is authenticated against a database that knows the token’s number and can calculate the same number.

Physical Security Definition

•The physical measures & their associated procedures to safeguard & protect against:

•Damage

•Loss

•Theft

Physical methods

As you have seen, there are many different ways that you or a business can lose valuable data. With a little bit of planning and thought however, the risks can be reduced or even eliminated.

Physical methods of protection are there to stop unauthorised people physically going to the computer and accessing the IT systems.

There are many things companies can do to make their equipment more secure:

Lock the room when not in use

Use swipe cards or keypads to activate locks

Bolt computers to the desk

Use special pens to mark their postcode onto the computer case

Keep windows shut - especially if on the ground floor. Use bars.

CCTV video cameras to monitor rooms where the computers are and also the corridors

In large firms, security guards

Passes which are checked by the security guards

Position the screen so passers-by can't see what you are working on

Make sure that nobody can see the keyboard whilst you are typing in your password
