The concept of personal security involves protection from personal harm rather than protection from an invasion of privacy. Personal security is a general condition that occurs after adequate efforts are taken to deter, delay, and provide warning before possible crime, if such warning occurs, to summon assistance, and prepare for the possibility of crime in a constructive manner. In the contest of Cyber Security, apply all necessary tools to protect yourself.

Computer or desktop security can be defined as controls that are put in place to provide confidentiality, integrity, and availability for all components of computer systems. These components include data, software, hardware, and firmware. Desktop security is not just a matter of protecting your own machine and the data on it. When a machine is compromised, one of the most common outcomes is that it is used to launch attacks to break into, or disrupt service  on other systems located anywhere on the Internet.  

There are many different ways to provide security for local area networks (LANs). Many of these apply to the common types of hardware that are used for these small, local network setups.

One common strategy is to install a firewall resource behind a single access point, such as an initial wireless router. It’s also appropriate to use specific security protocols like WPA or WPA2 for password encryption on traffic coming in from the internet.

Network Security and Information security, refers to protection of information and information systems from unauthorized access and any disruption thereof. The critical nature of information that is shared over the network necessitates advanced technological security measures. Cryptography, authentication, encryption, access control, authorization, are some of the key security mechanisms that are used to secure information.
