| 8.11.4 | The need to install anti-virus software on the server and workstation
Because traffic flows from network to network via the Internet, there is a larger chance of a virus coming over the Internet and onto the network. To prevent a virus from destroying a system or a network, it is important to install anti-virus software on the servers and workstations. Anti-virus software scans all the files that come in onto the network off the Internet and scans all the files opened on the server, which are considered to be outgoing. Without anti-virus software installed on the servers and workstations, no modern network will continue working efficiently and can be vulnerable to virus attacks and damages.
