Password Security And Picking A Secure Password

Picking a password is one of those things that absolutely everyone has to do eventually, though many passwords aren't very secure due to decisions in selection and upkeep. Regardless of whether the password is for a social networking website, an online seller, or simply just your email, all of your passwords must be kept as securely as possible in order to protect your assets and your identity.

Listed below are some methods to help you ensure that your passwords are secure:

* The ideal password size is between ten and fifteen characters long. This is generally short enough for you to remember but long enough to discourage a brute force attack (a common type of a password cracking attempt).

* Avoid passwords that are very easily guessed due to their association with you. Your name and the names of anyone in your family, for example, can be very easy passwords to crack. Additional quickly guessed passwords include names of pets or important dates including anniversaries and birthdays.

* Also avoid using any passwords which are actual words which can be found in the dictionary. There are actually many programs that try to use every word in the dictionary as a password. These kinds of programs also frequently try to add random numbers to a given word (such as turning "kitty" into "kitty2") or to spell words backwards, so those possibilities shouldn't be used as passwords.

* The strongest passwords are usually alphanumeric combinations (sequences of numbers and letters) that are not composed of actual words but instead are made of syllables that you can easily remember mixed with numbers. Using a mixture of capital and lowercase letters will also help ensure a secure password. Ideally, this combination is also pronounceable, rather than a random string of letters and numbers, as the pronounceable password will likely be easier for you to remember. For example, a password such as "vgie38hA" is very secure but not very memorable, while "Soe6bam" can be repeated to yourself out loud and therefore remembered much more easily.

* Passwords which contain obvious sequences may take a bit longer to crack, however they're by no means secure. "123456" or "abcdefg" are easily recognizable patterns that will almost certainly be attempted by absolutely everyone trying to guess your password, as are patterns based on keyboard layout like "qwerty" or "zaq1xsw2" (analyze the left side of your keyboard for the latter example).

* Use a different password for every occasion. Choosing to use exactly the same password for everything is regrettably common and very unsafe. Once the password is known to work for one use, it will be tried for all other applications. Using a different password every time prevents the loss of all security in the case that one password is compromised.

* Change your passwords frequently. The longer you keep the exact same password, the greater the chance that it can be compromised. Altering your passwords every six months or so helps to ensure that your passwords are secure even if they have already been discovered and simply never used.

* You may need to write your password down in the event you can't remember it. If this would be the case, don't leave the written copy of your password anywhere that's immediately obvious such as your desk or your wallet. One option is to lock it up somewhere (such as a filing cabinet, lock-box, or other secure container) for that you have the one key. Another possible method is to write the password down on the edge of a page in a favorite book - avoid writing it down on a bookmark placed in a book, however, are these are easy for you to lose and for an intruder to find.

* Never give your password to anyone. The best password is one that you, and only you, know. No one else needs to know you password - not your spouse, your family members, your buddies, or your co-workers. Your system administrator doesn't need to know your password, since that person really should be able to reset your password in case of emergency anyway.

Files, Folders and Defrag - Help Organise Your PCFiles, Folders and Defrag - Help Organise Your PC

What is a file?

A file on your computer is much like a file that you would keep in your filing cabinet. Each file has a unique name and is kept in a specific location. Each computer file has a three character extension which is separated from the file name by a period. The extension is often hidden however there is an option in Windows to display this if you wish. The extension relates to a specific program. This tells the computer which program to open it with. For example, a file extension xls or xlsx relates to Microsoft Excel.

Some file extensions, such as.mp3 can be opened in a variety of programs.

What is a Folder?

A folder usually contains a collection of files similar to a folder in a filling cabinet. You can have folders within a folder. These are known as subfolders. You may sometimes hear folders referred to as directories.

What is a Path?

A path relates to the exact location of the folder leading to the files. For example, the location of the files for a program installation on a Windows PC is commonly c:program files.

File names can be whatever you like however there are some characters which cannot be used. e.g. *! % etc.. If you store files in the manner which you would in a manual filling system then you should be easily able to locate the one you are looking for.

Any file can have a shortcut, which is like a bridge to the original file and can be placed in any location on the computer. The Desktop is a where you are likely to find several shortcuts.

Keeping Your Desktop Tidy

It is good practice to keep you desktop tidy and uncluttered. Remove all unused shortcuts and create folders for scattered files. In Windows there is a desktop clean up wizard to help with this process.

To access this right click on the desktop, choose properties, then select the tab, desktop. Then click the button customise desktop button. There will be an option to clean the desktop. You could of course just delete any unwanted shortcuts or icons.

Performing a Defrag on a hard disk for a Windows based computer is a useful way to help speed up access to files and folders on your computer.

What is Defraging (Defrag)?

If you were to index a filing cabinet, you would probably organise it alphabetically with labels on the individual files to enable you to find them easily. If someone moved around the draws on the filing cabinet and switched the labels on your files to

a random order, beside being a tad annoying to say the least, it would take a great deal longer to find a particular file. Now a computer saves files wherever it finds space. This can be almost anywhere on the hard drive. So when the computer accesses a file it may have to look across the entire hard drive to find it, so over time this process will take longer. What a defrag does is to group together files of similar types thereby increasing the speed of access to them. So carrying out a defrag on a regular basis can help optimise the time your computer takes to access files and folders. Windows 7 and Windows Vista have an option to schedule a defrag at regular intervals.
