Tips to Keep Your Password Secure and Confidential

baddoel — Sun, 24 Oct 2010 14:56:11 +0000

Passwords are secret codes that we should keep the security and confidentiality. Because so many negative things that can happen when we have the password was leaked into the hands of others. And usually it happens because of our own mistakes, such as fear of forgetting the password, so we wrote it somewhere or possibly make the password of the things close to our daily life such as birth date, name of child or loved one as well as other matters that are too easy to guess .

Here are some things that might be a consideration for us all when creating a password, so as not to leak or be known by others. So the things we do not want is not going to happen.

* Not Using Default Password
The default password is the password that we can be the first time. This default password should be quickly replaced because of very vulnerable. The reason, the default password can be easily searched on google search, even there are listed the name of a machine, type and default password with a magnificent plastered on some website creators vendors.

Sometimes administrators fear of forgetting to change-change the default password, so that an intruder can take over the system with default passwords.

* Password Hint Not To Wear
Sometimes we are afraid to forget the password that was our entry into the system / account, so we need to create a reminder if we forget the password. Now this is called password reminder Hint, if we create a password hint question with this then we can quickly recall these forgotten passwords.

Likewise with the hackers, they’ll experiment with us to guess the password in the password hint questions, over time the password will be predictable, if the questions listed in the password hint can be answered by the penebak password.

* Not Writing Password
Owners are often afraid to forget your password with the password has been entered, so the owner would write different passwords user id and password into other media such as a notebook, notepad, Stickies (mac), password folders, books, mobile phones and other.

It is also quite vulnerable to leaking. Why vulnerable? Because if the various equipment is lost, then all information about a user id and password are sooner or later will be known by the thief equipments / gadgets are missing.

* Using a Strong Password
Owner passwords often using a short password only, if it could be shorter than 3 characters then the user will give a short password. Fortunately this time the system provides a minimum password length of 6 characters and a maximum of 254 characters. The longer a password the stronger it will be the password security.

Strong passwords can be created with a combination of numbers and letters and even a variety of other characters. Some admins are currently using a password that is long enough, coupled with encryption such as PGP key and others, so it is quite difficult to guess password.

* Change Passwords Regularly
Owners should periodically change your password for authentication password, the more frequent password changes, the better, because the more difficult the penebak password hacking account / your system. Changes to the password depends on the owner, could be a week, a month, three months, and others. Originally the owner does not forget the password that was changed earlier.

* Not To Wear The Same Password on Multiple Accounts
Owners often forget and sometimes passwords frequently enough to create an account, so they each create a new account using the same user id and password are the same, this is very vulnerable and dangerous. Because these passwords through a single account, all accounts will be taken by the hacker.

* Using Password Management
To help recall the various passwords and various accounts, we are often very difficult, but not to worry because it has many current applications to help organize our passwords. This application can be downloaded for free from the internet and paid, so that regardless of our account and whatever we can with the password easy to remember and re-opened, of course, to open it with an encryption method as well.

Tips to Fix Slow Network File Copy in Windows 7

baddoel — Sat, 03 Jul 2010 06:22:24 +0000

You may experience poor file copy performance over the network in Windows 7 PCs. This could be caused by the Wndows “Remote Differential Compression” engine. Remote Differential Compression is a Windows feature introduced in Windows Server 2003 and is available on all later versions of Windows. This Windows feature is enabled by default in Windows 7.

Remote Differential Compression (RDC) allows data to be synchronized with a remote source using compression techniques to minimize the amount of data sent across the network. RDC is different from patching-oriented differencing mechanisms, such as Binary Delta Compression (BDC), that are designed to operate only on known versions of a single file. BDC requires the server to have copies of all versions of the file, and differences between each pair of versions are precomputed so that they can be distributed efficiently from a server to multiple clients.
There seems to be a problem with this Windows 7 and disabling this feature resolves the problem with slow file copy performance.
To disable Remote Differential Compression,

To disable Remote Differential Compression,
1. Click Start – Control Panel – Programs – Trun Windows features on or off
2. Uncheck “Remote Differential Compression” and click OK.
3. Restart the computer and you should see an improved performance with copying files.
