The internet is a publicly accessible global network of computers. The internet is completely decentralized, and since it evolved over the decades without any security strategy at its core, it has many security loopholes. Each time a computer connects to the internet, it becomes a part of the internet as well as an interface of two-way data transit. This makes every terminal vulnerable to various forms of attacks.
Internet security is an area of network security that is concerned with securing individual and networked computers from security threats on the internet, without compromising on the access to the internet. The approaches involved are various.
Since the internet is based on the server-client architecture, security on the server side is ensured through firewalls, routers, NATs. This ensures that vulnerabilities at the server side do not reflect on insecurity within the network and at the client side. The same security strategies are followed at the client side as well. Secure browsers with lesser known vulnerabilities are advised. Spy and Advert checking software keep a constant check on malicious and disturbing programs that enter the system without user knowledge. Various anti-virus software as well as firewall software provide added security. The many standards organizations and other institutions like the W3C (World Wide Web Consortium) are intent on devising a more secure internet backbone from the ground-up which they have tentatively named Web 2.0.
Despite the presence of all such procedures, the best protection is being informed. It should be known that the internet is a platform for much malice and that vulnerabilities will always exist. The best strategy is to minimize the potential loss, not indulge in activities that give any scope to infection (like running unknown programs), better netiquette, proper updating of virus definition files, etc.
