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.
