Enterprise Security - Case Study Report - Security Architectural Design - IT Assignment Help

Assignment Task:

A. Task: 

Provide a security architectural design for the Logical and Higher Schooling (LAHS), a NSW  department of the Ministry of Education, whose brief it is to provide a range of tertiary courses  in the field of applied technology. LAHS is currently implementing new IT systems, something  that also requires a complete overhaul of their IT security. This latter task is your  responsibility. LAHS is worried about several security issues: 

1. Compliance with departmental security policies and privacy legislation, 

2. Cybersecurity - attacks from external sources, as well as from internal sources (rogue students), 

3. Confidentiality of student records, 

4. Protection of LAHS computer systems from inadvertent damage. 

LAHS NSW has IT systems in all of their offices: 

Head office 1 - central administration of staff and students, central office systems Regional offices 8 - student records, regional office systems, payroll 

Regional campuses 40 - IT teaching laboratories, staff workstations, local office systems (file  servers, printers)

B. Components to deliver: 

1. High-level security architecture (SABSA contextual and conceptual levels). I suggest that  you use reference architectures if you can find these. The purpose of this work product is to  show what types of security services you intend to provide, what types of networks and  servers are required, for each type of location (head office, regional office, regional  campus). 

Indicative example only: 

You will need to make reasonable assumptions about sizing, capacity, etc. of the various IT  systems, and you need to provide a design for best security practice, i.e. cost is less of an  issue than having security exposures and weaknesses. 

2. Detailed (SABSA logical level) security architecture for each type of office (HO, RO, RC).  This will include specific details of what security services you will provide at office type, what  networking you will provide, what application systems you will be protecting, what tools you  will be using. 

3. Detailed design (SABSA physical level) for HO, 1 RO, 1 Campus. This will include security  equipment, networking devices, storage sizing, management tools, operational components  for the detailed security architecture.

Indicative example only:

4. Costing estimates (both labour, hardware and software, both for implementation and operation) 

5. Planning estimates with enough detail to show estimates at the equipment installation level

6. Resourcing estimates 

For these latter components, you would benefit from using the SABSA Framework for Security  Service Management.
