NETWORK IMPLEMENTATION AND ACCESS RESTRICTIONS

Summary
As of present day, segmentation of networks and internally securing of these network
segments play a significant role in preventing networks from getting compromised by threats
of hackers, and other cyber security attacks. The report proposes a network for alm.co.uk
where such segmentation are created and appropriate security measures for these segments
are put in place. First the report summarizes the requirements of ALM network where the
number of devices for each segment, the access restrictions, and the kinds of servers installed,
and the specific subnet classifications are mentioned. Then the report provides the network
design which has been drawn and configured in Cisco Packet Tracer 6.2 after which the
network design and architecture gets explained in detail. Next the IP addressing and the
subnet classifications of the network is provided in tabular format and discussed thereafter
with respect to the subnets for each segment. Then the implementation of the VLANs is
shown, and the report discusses how the VLANs get implemented to ensure the inter VLAN
routing works. Thereafter the report talks about the access control list extended commands
for prohibiting the departments from accessing one another. All restrictions available through
ACL commands is shown as well as how the departments are restricted. Next the report
provides the tests and validations to check whether the network proposed meets the
requirements of AML. Then after discussing the IP addressing protocol the report ends with
concluding notes.

Introduction
The following report highlights the importance of segmentation of networks and
internally securing of these network segments play a significant role in preventing networks
from getting compromised by threats of hackers, and other cyber security attacks. The report
aims to propose a network for alm.co.uk where such segmentation are created and
appropriate security measures for these segments are put in place. The report begins by
summarizing the requirements of ALM network where the number of devices for each
segment, the access restrictions, and the kinds of servers installed, and the specific subnet
classifications are mentioned. Then the report provides the network design which has been
drawn and configured in Cisco Packet Tracer 6.2 after which the network design and
architecture gets explained in detail. Next the IP addressing and the subnet classifications of
the network is provided in tabular format and discussed thereafter with respect to the subnets
for each segment. Then the implementation of the VLANs is shown, and the report discusses
how the VLANs get implemented to ensure the inter VLAN routing works. Thereafter the
report talks about the access control list extended commands for prohibiting the departments
from accessing one another. All restrictions available through ACL commands is shown as
well as how the departments are restricted. Next the report provides the tests and validations
to check whether the network proposed meets the requirements of AML. Then after
discussing the IP addressing protocol the report ends with concluding notes.
Requirements
The small network of the company alm.co.uk is to consist of four different LAN
configurations for four different departments along with LAN configuration for the servers
and the wireless network.
