Introduction to Network security

Effective network security strategy involves identifying the relevant threats or vulnerabilities, and deploying effective tools to overcome such threats.

In the field of networking, the area of network security consists of the provisions and policies adopted by the network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of the computer network and network-accessible resources.

Wireless networking is prone to some security issues. The risks to users of wireless technology have increased as the service has become more popular. Wireless security is the prevention of unauthorized access or damage to computers using wireless networks.

Internet security is a branch of computer security specifically related to the Internet. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet represents an insecure channel for exchanging information leading to a high risk of intrusion or fraud.

Data security is the means of ensuring that data is kept safe from corruption and that access to it is suitably controlled. Thus data security helps to ensure privacy. It also helps in protecting personal data.
