Internet Security refers to taking appropriate steps to protect all types of computing systems, both serving information (servers), and retrieving information (clients) but connected through the Internet via a request and response mechanism. This is built on the principles of authentication, validation and authorisation.
Also, appropriate measures are taken to protect data in these Internet computer systems. Data must not be compromised and is protected against hackers and malware, spyware, viruses, worms, and those viruses which contain trojan horses through the use of appropriate applications which detect threats early on. Internet servers are protected against DDoS attacks by the use of deflectors contained in solutions such as Radware provides.
The term, "internet security", refers to measures taken to safeguard computers against security threats that are an integral part of having Internet service. It can also refer to techniques to ensure that data stored in a computer cannot be read or compromised by anyone, individuals or groups without proper authority. Most common security measures involve data encryption and passwords and in today's environment, multi-factor authentication.
The most common precautions against these kinds of compromise are NAT routers, which protect computers that are connected by a single high-speed link from being penetrated. Another common form of protection are firewalls, which restrict unauthorized entry via hard-coded access lists.
On the client side virus protection, anti-spyware and anti-adware software protects computers. All of these solutions are a protection against unwanted pop-ups, slow computers, and leaking private user information. Many solutions involve the use of server-side applications which control clients safely and without the risk of the users altering the software which is protecting their computers.
