Computer security is a branch of computer technology known as information security as applied to computers and networks. Security for personalized web servers, small business server, dedicated server is in demand these days. Everyone wants their data safe and secure.
The basic Security Measures are as -
1. Choose a secure operating system - If you care about your data, pick an operating system that is secure.
2. Enable a strong BIOS password - BIOS password locks the hard drive so it can't simply be removed and reinstalled into a similar machine.
3. Use a personal firewall on your - Corporate networks protect their Servers and Workstations by configuring a firewall to prevent intruders from hacking back into their systems via the company's internet connection
4. Use the NTFS file system - Use the NTFS file system to protect your data from thieves who may try to access your data. FAT and FAT32 File systems don't support file level security and give hackers a big wide open door to your Computer, Web Server, Small Business Server, Dedicated Server.
5. Disable the Guest Account - Always double check to make sure the guest account is not enabled. For additional security assign a complex password to the account anyway, and restrict its logon 24x7.
6. Rename the Administrator Account - Renaming the Administrator account will stop some amateur hackers cold, and will annoy the more determined ones.
7. Creating a dummy Administrator Account - Another strategy is to create a local account named "Administrator", then giving that account no privileges and impossible to guess +10 digit complex password.
8. Prevent the last logged-in user name from being displayed - When you press Ctrl-Alt-Del, a login dialog box appears which displays the name of the last user who logged in to the computer, and makes it easier to discover a user name that can later be used in a password-guessing attack.
9. Enable EFS (Encrypting File System) - Be sure to enable encryption on Folders, not just files. All files that are placed in that folder will be encrypted.
10. Disable the Wifi or communication port.
11. Backup your data before you leave - Backing up your hard drive before you leave can help you retrieve your data.
12. Consider using offline storage for transporting sensitive documents.
