What is Computer Security Software?...
Computer security software has jumped up in priority with the internet becoming popular with the general population worldwide.
Hackers, vandals and the commercial world are making things more and more difficult for us everytime we connect to the internet.
Hackers and vandals are getting into other people's computers and committing pranks like wiping out your hard drive.
The more serious offenses could even be stealing your identification and stealing money from your bank account.
So with increased wireless technology and faster broadband internet connections you must set up computer security software to protect you and your computer.
We'll be covering the following computer security software to help secure your computer system:
- Passwords
- To protect access to your computer, every user account should have a password.
- When you first turn your computer on you'll go right past the Welcome screen and automatically log in.
- Log on Windows XP
- Set up each user account and passwords for every user account.
- Select "Start" in the bottom left corner of the desktop (the initial) screen.
- Select "Control Panel", "User Accounts", "Owner - Computer Administration".
- Select "Change my name", enter your name, and select "Change Name".
- Select "Create a password", enter a new password twice, enter a word or phrase hint, and select "Create Password".
- Create another user account and password for other users.
- Note - You need at least one Computer Administrator to:
- Create, change, and delete accounts
- Make system-wide changes
- Install programs and access all files
- Close the User Account window by select the "Red X" in the top right corner.
- Log off Windows XP
- Select "Start" in the bottom left corner of the desktop screen.
- Select "Turn Off Computer", and "Turn Off".
- Password Guidelines
- Always assign a password to the Administrator account to prevent unauthorized access to the account.
- Determine whether the Administrator or the users will control passwords.
- Using no password at all is not a good practice because it is then easy for other users to just walk up to an unsecured computer and log on.
- Use Strong Passwords.
- Creating Strong Passwords
- Weak passwords are a big security risk. Use the following guidelines:
- Passwords should be at least eight characters long - and longer is better.
- Passwords should use a combination of lowercase and uppercase letters, numbers, and symbols (for example, ~!@#$%^&*()_+-={}|[]:";'<>?,./ or a space character)
- Passwords should be changed regularly.
- Password Safe
- Keeps all your passwords and personal data secure with 256-bit encryption.
- It's easy to use and offers quick, fast and secure password and personal data management.
- One 'Master Password' is all that is needed to access all your passwords and personal information.
- Use Password Safe to store:
- Web site passwords
- Credit card and PIN numbers
- Computer logon passwords
- Telephone banking codes
- E-mail passwords
- Software access passwords
- Door entry and alarm codes
In addition to passwords to protect you, additonal computer security software may be used, like a firewall.
Firewall
- A firewall protects a computer from attacks coming from the internet by blocking the incoming network traffic except the ones you allow in.
- Any computer connected to the network whether the computer provides internet connection services to other computers on the same network or is a stand-alone computer - should have a firewall enabled.
- Windows Firewall
- Windows XP Service Pack 2 (SP2) came out with the Windows Firewall. If you still have a previous version of Windows XP, you should think about upgrading to SP2.
- It is a host-based firewall that drops all incoming traffic that does not meet one of the following conditions:
- Valid traffic that is requested by the computer.
- Valid traffic that you have specifically configured the firewall to accept.
- If you have SP2 installed, follow these steps to confirm the firewall is enabled:
- Select "Start" in the bottom left corner, select "Control Panel", select "Windows Firewall".
- Select "On (recommended).
Another area for computer security software would be to protect your files and folders.
NTFS (NT File System)
- This is the preferred file system for Windows XP because of the following features:
- File- and folder-level security - NTFS allows you to control access to files and folders.
- Disk compression - NTFS can compress files to store more data on the partition.
- Disk quota - NTFS allows you to control disk usage on a per-user basis.
- Encryption - NTFS allows you to encrypt file-data on the physical hard disk by using the Microsoft Encrypting File System (EFS).
Encrypting File System (EFS)
- The process of making information indecipherable to protect it from unauthorized viewing or use.
- A strong public key-based cryptographic scheme encrypts all files in a folder.
So in summary, your computer security software should at least cover having strong passwords, firewalls, and using the NTFS file system to protect other's access to your files and folders.
