System Preventive Assessment: Mapping the System and Reporting of Issues

Background of Case study:

You work in the IT department of a small organisation, Central ImagiLife employing 18 staff (excluding the IT staff), and a large number of causals in the sales department, which at times can run into around 100 sales staff.  Your organisation deals with Life Insurance, and carries a large brokerage team in the sales. 

Your office sits on Level 30, 35 St Georges Terrace, on a 500 sq m space area.  The organisation has a number of sections including Management and Training team, the Operations Team, the marketing and support Team, the Accounts Team, the Compliance Team.  The company has one IT lead and two other IT Support staff.

The IT assets consist of three routers (CISCO1841), of which one is meant for redundancy.  You have three legacy switches (Cisco SRW2008 8-Port Gigabit Switch) in the office.  The switches and routers sits on a trolley rack in a room shared by the IT lead, maintenance and cleaners.  There are also two Ubiquiti UniFi Access Points, which are ceiling mounted in the clear view of anyone in the office.

The company has twenty-four workstations, with i5 core processors, spread out amongst all the departments.  Most of the machines are used by the in-house staff but there are four workstations that are allocated to the sales staff.  All systems runs on a Domain, managed the AD.  The machines used by the sales staff break down very often, cause lock-out because of wrong password etc.  Often, these machines are also infected by viruses, and sometimes the sales staff will watch movies on the machines when they have some free time.

The company runs a local Web Server on a Dell R610, which is outsourced for management to a small local IT company, Asterisk Consultancy, which does the content management, analytics reporting and security management.  Asterisk also provides off-site backup for the company’s compliance depository as part of legislative requirements.

Otherwise, the company runs and manages it’s own IT assets and more importantly manages it’s own file server and uses Speedview to manage their documents and compliance documentations.  The file Server is deployed on another enhanced Dell R610 machine.  Both the servers sit in a room shared by the IT lead, maintenance and cleaners.[Learn about Virtual Private Network] 

One of the bigger issue is the sales staff, who would normally BYOD, creating lots of issues for the IT staff on compatibility issues as well as security policy breaches.  The sale staff can get abusive at times because of the inability to gain access to services. 

Assessment Tasks: 

You will conduct a research on the security posture of the company, and if necessary work with Asterisk Consultancy.  You will propose a possible network and system diagram to show how a workable system may look like for Central ImagiLife.  You will also put in specific recommendations to improve on troubleshooting of equipment, system and software faults.  You will also look into the security of the IT infrastructure.  You will cover these and present the information in a simple report not exceed five pages, with clear headings and sub-headings to simplify reading.[Read about System Development User Manual]
