Summary
Segmenting networks play an important role in ensuring security and privacy within a
network. The network being proposed by the report tries to implement one such network for
alm.co.uk and segments it by using different VLANs for the different use cases including
subnetworks of the four departments. First the report lays down the requirements of the
network and summarizes the device requirements of the four departments in a tabular format.
Then the report presents the network design diagram after which the report discusses the
implementation of the network as well as justifies it. After that the report provides the
subnetting details of the various segments and highlights the networks, subnet masks and
CIDR for each segment. Thereafter the six different VLANs of the six segments are talked
about and the subnetworks they serve is noted. The report also explains how the departments
get restricted from accessing other departments using the access control list extended
commands. Then testing is conducted on whether the access restrictions are effective and if
the devices are able to automatically obtain IP addresses using the DHCP protocol. After this
the report ends with concluding notes.

Introduction
It is because segmenting networks play a vital role to ensure security and privacy in
networks, the report proposes a network for alm.co.uk where it tries to implement such
segmentations with the help of VLANs for the different use cases including subnetworks of
the four departments. The report begins by laying down the requirements of the network and
summarizes the device requirements of the four departments in a tabular format. Then the
report presents the network design diagram after which the report discusses the
implementation of the network as well as justifies it. After that the report provides the
subnetting details of the various segments and highlights the networks, subnet masks and
CIDR for each segment. Thereafter the six different VLANs of the six segments are talked
about and the subnetworks they serve is noted. The report also explains how the departments
get restricted from accessing other departments using the access control list extended
commands. Then testing is conducted on whether the access restrictions are effective and if
the devices are able to automatically obtain IP addresses using the DHCP protocol. After this
the report ends with concluding notes.

Requirements
The network of the client company alm.co.uk must consist of four departments.
The network should additionally contain four servers, namely the web server, the email
server, the DNS server and the file server.
All of these servers are required to be shared among all the respective users of the different
departments.
