Why destroy encrypted data?

Although data encryption is one of the most important data protection methods, there is no guarantee that 1) the password (or key) will always remain confidential and 2) the encryption will protect the data permanently (in other word for an infinite period of time) even if the password always remains confidential. Destroying data allows the data to be protected permanently. Hence, it provides another protection layer to the data whether or not the data is encrypted

How to hide user names from the logon screen

Hiding user names enhances security. Attackers have to guess both username and password. It is also useful when you have a forced account setup in your computer.

You can hide user names by editing the registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows

How to create a forced account.

A forced account is a computer user account that is configured to destroy sensitive data in a forced logon or a logon as a result of forced username and password disclosure.

The following steps create a user account, which you can use it as a forced user account.
  1. Click Start and click Control Panel.
  2. Click Add or remove user accounts under User Accounts and Family Safety.

  9. Type in a password for the user account and an option password hint.
  10. Click Create password button

How to press the mute button automatically

When an alarm goes off except theft alarm, there is a mute button on the screen. The mute button allows you to stop the sound. By the default setting, the alarm sound will continue until the mute button is pressed. You can configure LAlarm to press the button automatically.
For example, if you want LAlarm to automatically press the mute button within 30 seconds from the health alarm going off, do the followings:
  1. Append "-mute30" string to the end of the sound filename. For example, chirping-mute30.wav.
  2. Start LAlarm Options.
  3. Click Sound tab.
  4. Choose "chirping-mute30.wav" for health alarm sound file. (e.g. c:\users\[username]\music\ chirping-mute30.wav)
  5. Press OK.
After the above procedure, LAlarm will press the mute button 30 seconds after the health alarm going off. As a result, the alarm sound will stop. You can specify a different amount of time instead of 30 seconds. You can also configure other alarm by using the above procedure above except panic alarm and theft alarm.
