Suggestions To Update Security in Windows® 7
What are the various ways of updating security in Windows 7?
We know that all the Operating Systems are prone to virus attacks, unauthorized hacking etc. In such cases, security software should be installed and updated. If you are sending and receiving mails through the Internet, it is necessary for you to install and update security software including antivirus, anti-spyware, and antimalware programs. The firewall in your computer can protect the system against spyware or any other worm intending to hack your relevant data. But it cannot block the worms or malware in the e-mails. So if you open such messages, your system will lose all the data. Antivirus should then be installed and updated for the efficient and fast performance of your Personal Computer (PC). Anti-malware producing companies like Norton Internet Security 2009 are producing these types of software to protect your PC from the latest threats on the Internet.
The three main advantages of updating security in Windows 7 are:
- Recover data when hardware fails
- Protection against viruses, spyware, and malware
- Blocking unauthorized access
Recover data when hardware fails
A technology called Bit locker is incorporated in Windows 7 to improve security. This automatically locks the data to be protected. So in case the system is stolen, its data can't be accessed by unauthorized persons. The Bit locker uses complex keys and passwords to ensure locking. It also keeps changing the password regularly. Access to the locked data is possible only if you perform the data recovery process involving access to these keys and passwords.
Protection against viruses, spyware, and malware
Viruses, spyware, and malware are software programs used for destroying data in computers. Many websites contain them and if you open them, they may enter into your system and all the data in your system will be lost. The firewall program can be used to save the data from the attack of spyware. But the malware contained in your mail cannot be checked by firewall. In such cases, install and update antivirus software in your machine.
Data encryption and boot integrity protection are the two features allowed in Windows7. The data stored in hard disk is encrypted i.e. the data is converted into a special format that is not readable to humans. By means of encryption, it prevents external illegal access to data. When the user wants to access it, the data is reconverted into human readable form or is decrypted. Special keys are used for the purpose. To avoid any difficulty in using these complex keys, they are included in active directory and special steps are taken to use the security keys easily.
