A Floor Plan Layout of Micronet Gadong 2nd Floor 

Micronet Gadong Campus 2nd Floor layout

In 2nd floor, it has two sections where each has 2 rooms either a Lab or a Classroom. It also has two rest room for each section. For my suggestion, I would like to put 1 firewall, 1 VPN and 1 Network Access Control on the 2nd floor of Micronet campus. A firewall helps to prevent malicious software or attacks.  A VPN provides secure connection and extra security. A NAC provides user or system authentication and improve network security by limiting to authorized personnel.

Classroom 1:

• 1 projector
• 1 PC
• 1 projector screen
• 2 CCTV 

Lab 3:

• 1 projector
• 1 projector screen
• 1 switch
• 1 router
• 1 printer
• 2 CCTV
• 25 PCs

Lab 5:

• 1 projector
• 1 projector screen
• 1 switch
• 1 router
• 1 printer
• 2 CCTV
• 29 PCs

Lab 6:

• 1 projector
• 1 projector screen
• 1 switch
• 1 router
• 1 printer
• 2 CCTV
• 27 PCs

Business Intelligence

Exercise: Systems and Technologies
Explain each system and include the features, advantages and disadvantages. Identify in which level does it operate. Provide diagram where necessary.

1. Transaction Processing Systems (TPS)

• It is s type of Information System that use in everyday operation which functions as a collecting, storing, modifying and retrieving the data transactions of an enterprise.
• Features:
• Must be two parties 
• It takes two parties for the transaction to take place. There cannot be a giver unless there is a receiver. e.g. X borrows $10,000 from a bank. So it can defines as a transaction happens since there a two parties (X and Bank).
• Must be measurable in terms of money
• The event is not consider as a transaction if it is not financially viable
• Advantages:
• Operations handling 
• able to handle several transaction at once and making  your online transaction process easier as the system provide online processing process.
• e.g. thousand purchases, debit accounts, hold each person's private banking and address information, process customer orders
• Untapped Market
• able to reach and gain customers from around the world which allow people to access and buy your business's products or services.
• Disadvantages:
• High setup costs
• Lack of standard formats
• Hardware and software incompatibility 
• The Operational decision are the level of business decision operating at TPS.
• e.g. receipt / banking process / employee data / inventory / sales orders / purchasing transactions / sales transactions.

2. Management Information Systems (MIS)

• An MIS provides managers with information and  support for effective decision making, and provides feedback on daily operations.
• Providing information from TPS.
• Features:
• Flexible - allows analysation and evaluation of data from multiple sources and in multiple ways or processing. It allows the introduction of new ways to process data.
• Easy to use -  managers does not need advanced knowledge in information systems in order to get the information they need.
• Reliable and accurate - to improve efficiency in the organisation and ensure the decision making is of high quality.
• Advantages:
• Better decision making - by providing relevant information to decision makers.
• It is an integrated systems which allows communication among executives, managers, department heads and employees to improve
• Better communication = better management
• Quality of products or services improves by referring to information about customer feedback and past experiences.
• Disadvantages:
• Expensive to setup and maintain - you need to buy the systems to apply MIS
• Need to learn technical skills to use MIS
• Need to keep up when new tools are integrated into the system
• Upgrading the system requires extra money and staff
• Possibilities of data breach as MIC is connected online
• The Tactical decision are the level of business decision operating at MIS.
• e.g. Scheduled report / Demand report / Key-indicator report / Exception report.

3. Decision Support Systems (DDS)

• It is use to supports business or organizational decision-making activities. DSS serve the management, operations and planning levels of an organizations (usually mid and higher management) and help to make decision, DSS can be either fully computerized, human or a combination of both.
• Features:
• Facilitation - DSS facilitate and support specific decision making activities and decision process
• Interaction - it is a computer-based systems design for interactive use by decision makers or staff
• Advantages:
• Time saving
• Enhance effectiveness 
• Improve interpersonal communication
• Competitive advantages
• Cost reduction
• Increase decision maker satisfaction
• To promote learning
• Improves personal efficiency
• Disadvantages:
• Monetary cost
• Overemphasize decision making
• Assumption of relevance
• Unanticipated effects
• Obscuring responsibility
• False belief in objectively
• Status reduction
• Information overload
• The Strategic decision are the level of business decision operating at DDS.
• e.g. Product pricing / profitability / forecasting / risk analysis system.

4. Expert Systems (ES)

• User supplies facts or other information to the expert system and receives expert advice or expertise in response. 
• An intelligent computer program that uses knowledge and inference procedures to solve problems that are difficult enough to require significant human expertise for their solution.
• Features:
• 
  
• Advantages:
• Low accessibility cost
• Fast response
• Not affected by emotions unlike humans
• Low error rate
• Capable of explaining how they reached a solution.
• Disadvantages:
• ES have no emotions
• Common sense is the main issues of the ES
• It is developed for a specific domain
• It needs to be updated manually. It does not learn itself.
• Not capable to explain the logic behind the decision.
• There is NO LEVEL for ES because all the decision is decide by the systems not by the operation /  a person.
• e.g. Diagnose of human illnesses /  make financial forecasts / schedule routes for delivery vehicles.

Network Security

Network Planning - Proof of Concept

How to design a secured network (methods):

ZAWANAH

1. Identify the network assets (hardware, software, employee)
2. Analyze the security risks (hackers)
3. Analyze the security requirements (backup)
4. Develop a security plan (plan if any of the security risk happen)
5. Define a security (rules of the security, e.g. don not change the setting of the computer)

SABRINA

1. Set clear administrator Privileges
2. Secure your private network
3. Secure endpoints by Configuration Demilitarized Zone (DMZ)
4. Monitor the network
5. Maintain Firewalls
6. Establish Intrusion Detection and Prevention Systems
7. Protect Remote Access

HAZWAN HASSAN

1. Exam the system of the company
2. Interview employee what they know and what kind of guide they've received
3. Start planning design
4. Set up Firewall
5. Set up IP router

HAZWAN HAILE

1. Prepare - identify the assets (hardware, software, employee)
2. Plan - make sure all the devices are listed down such as network devices, connection, security.
3. Design - draw the draft sketch of the design
4. Implement - create the network by following the design draft
5. Maintenance - configure the setting of the network design
6. Testing - test the implemented network design to make sure it is working and connected

MISS J

1. Identify all the assets (hardware, software, employee. e.g. identify what they need or what they already have)
2. Identify the budget
3. Identify the problem (virus, hacker)
4. Identify the solution (installing anti virus to prevent viruses, installing firewall to prevent hackers)
5. List down all the software and network security hardware
6. Identify the secure connection (what are the cable that suitable to use and how to connect)
7. Sketch and plan your design
8. Ask for the approval from the organization itself (is it design good or no? ask approval until it get approval)

The different types of network security designs that will aid good network security:

FARAH

1. Antivirus
2. Network Access Control (NAC)
3. Data Loss Prevention (DLP)
4. Email security 
5. Endpoint security
6. Firewall
7. Intrusion Detection System & Intrusion Prevention System
8. Virtual Private Network (VPN)

SYUKRI

1. Network Access Control (NAC)
2. Application Security - secure all the apps of the software that network use
3. Email Security 
4. Antivirus and anti-malware software
5. Wireless Security 

ERRA

1. Firewalls - monitor the incoming and outgoing traffic
2. Virtual Private Network (VPN) - allow remote access to secure corporate applications or other resources
3. Network Access Control (NAC) - strengthens network by controlling its access
4. Data Loss Prevention (DLP) - responsible for securing the communication network of an organization in order to protect its sensitive data.
