Web Security

Although the Internet can be seen as an invaluable tool for personal, educational and business purposes we must realize it's also used for things such as pornography, identity theft, money swindling scams and various other illegal activities. You have to be careful to protect your privacy as much as possible when online. You can use a firewall to protect yourself from potential hackers and offensive websites as it basically places a barrier around your computer and filters information coming into it. You can customize a firewall to block information from specific computers, or domain names, but even though it's designed to stop viruses and spam reaching you it's impossible to stop everything so you should also install separate anti virus and anti spam programs. Web security is essential for business and personal computers and while firewalls can stop anyone from logging onto a computer in your private network you may also want to use other security devices such as passwords, parental control and anti spy ware programs.
