                 Install Firewall
                 Firewall could be either a software or hardware that helps in keeping a network secure. It analyzes the
                 network traffic (flow of data) and determines whether the traffic should be allowed or not in the network.
                 It also blocks unauthorised users to access data on the system. It can even keep a check on malware
                 attacking the system.


























                 In most cases, operating systems such as Linux, Windows or Mac include firewall software as a part of
                 operating system, thus keeping a computer secure but in some cases, a user needs to configure firewall
                 in the network for additional security.

                 Never Install Software from Unknown Sources

                 Before  downloading  and  installing  a  software,  verify  the  source  of  the  supplier  to  find,  whether  it  is
                 legitimate or not by searching the internet or referring to the reviews of the other users. A user should
                 understand the nature, the purpose and given terms of the software before attempting a download and
                 installation.
