Computer Security Issues Facing Alsager Ltd.

In upgrading the Alsager Ltd IT facilities, despite numerous advantages that the new
systems brings one has to be made aware of the possible threats posing.

Virus can effect the system. They are pieces of codes created by hacker to create a
nuisances and to another extreme corrupt valuable data. Examples of these can be animated
icons flying pass the computer screen and to another extreme can be programmes designed to
delete the hard drive. The Computer Virus can be caught through a number of ways. The most
highly publicised way, is through the Internet, other ways are through removable storage
media, such as floppy disks and zip drives. They can also be caught through computer
networks, where a third party from another machine in the network introduces the virus
(accidental or otherwise) which then spread throughout the network. The most unlikely way
of virus contaminating the system is through malicious employees creating them on the
system but this will be discussed later on. There are a number of precautions that can be
taken to help prevent this. By simply making employees not to use mobile storage media
unless they know where it has been, making them aware that pirated media ,
shareware/freeware programmes may be potentially dangerous. A talk and leaflet
distribution to employees could be useful. If the Alsager decides to connect to the
Internet, this would be another potential source for virus and such like. A firewall

preventing virus is to subscribe to a antivirus programmes, although this will not give
you 100% percent protection it will help prevent the majority of known virus. An important
note to this point, is the importance of getting regular virus updates from the software
manufacturer .

With the introduction of the IT facilities, the amount of room information takes up is
drastically reduced from a whole filing cabinet to a small hard drive. Information can be
easily copied and since the advent of the Internet, information does not even have to be
on a psychical media to leave the building. This therefore makes it much more easier to
copy and take out valuable information. All the companies details, there accounts and
their customers account are prone to the risk. A single person can take out all the
information on a zip disk or even a floppy disk depending on the size of the file. This
poses the risk of company espionage and financial fraud, through the use of customers
credit card details. There are a number of ways to help deal with this problem. The system
should be a closed network. This means, that only people authorised to access the
information may only do so through a user name and password. In this system there should
be a heirachy of privileges, so only people who need to access the most sensitive
information may do so. Also by having a login system, people using the system can be
