La Reina Network Solutions $($LNS$)$

Joe Blog founded a small networking start$-$up near Milton Keynes in $2020.$ His company

began by delivering small$-$scale network solutions and has since grown to become one of

the most significant networking organisations in the South East. They have grown in terms

of resources, staff, and clients over the last $10$ years, and they now have plans to spread

their business across the country by establishing several satellite sites. As a network

architect who recently joined the company, you were tasked with collaborating with the

LNS$$s project team to build a site with two hundred users.

You are expected to demonstrate your understanding and expertise by writing a

report that contains the following information:

$$ Computer Architecture, Network models, and infrastructure.

$$ Information, data, and network security.

$$ Security threats and protecting Networks.

$$ Security compliance.

You are required to answer the questions in the below parts in the context of the

above scenario.

Part $1-$ Computer Architecture, Network Models, and Infrastructure

$1\mathrm{.}1$ You are giving LNS advice regarding a range of application software and

operating systems. For the project team to make an informed decision on its

procurement, compare similar operating systems and application software

systems using examples.

$1\mathrm{.}2$ The project lead stated that to properly construct a new network, it is

necessary to give a brief overview of popular physical topologies, a minimum

of two, contrast them, and clarify the distinctions and functions of each to

decide suitable topologies for their satellite site.

$1\mathrm{.}3$ List four application layer protocols that should be implemented and explain

how each will be used in LNS$\text{'}$s satellite site.

$1\mathrm{.}4$ Guests will have access to free Wi$-$Fi at each location. However, visitors have

complained about Wi$-$Fi access and coverage at a number of its existing

locations. Describe in detail how you intend to establish a reliable wireless

network at the new satellite site, which could provide a solution for a better

experience and security.

Part $2-$ Information, data, and network security

$2\mathrm{.}1$ Customers must register for their accounts online with LNS$.$ Explain in detail

how multifactor authentication can be used to protect customers' personal

information while they use LNS$\text{'}$s website.

$2\mathrm{.}2$ Computer networks may be the target of cyberattacks. Give an in$-$depth

description of how the IPsec will protect LNS from cyberattacks.

$2\mathrm{.}3$ Discuss in depth the various types of Network Security devices that can be

deployed to protect LNS$.$

Part $3-$ Security Threats, protecting Networks, and Security Compliance

$3\mathrm{.}1$ Explain in depth how LNS makes sure the CIA's guidelines are followed effectively

when they build their new satellite site. Give specific examples for each.

$3\mathrm{.}2$ Discuss in detail five benefits of implementing network monitoring systems with

supporting reasons for LNS$.$

$3\mathrm{.}3$ Explain in detail how an intruder might employ each of the following cyber security

threats to obtain unauthorised access to the LNS$\text{'}$s network:

$$ Dos and DDoS attacks

$$ Phishing attacks

$$ Password attack

$3\mathrm{.}4$ Edge computing is typically characterised as computation performed at the

network's edge. Describe in detail the various network security edge devices that

LNS may use to protect its infrastructure.

$3\mathrm{.}5$ Describe the key elements of an information security management system $($ISMS$)$

and how they apply to LNS network infrastructure.
