Business Intelligence - System and Technologies

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

Transaction Processing Systems (TPS)

• It is an information processing system for business transaction that involves the collection, modification, and retrieval of transaction data
• Characteristics, include performance, reliability, and consistency
• Example: Credit card transactions

Characteristics:

• Reliability 

Failure rates must be low

If failure occurs, the recovery must be quick

• Controlled processing

Support the organization's operations

TPS should maintain the requirements of the roles and responsibility's operation

Management Information System (MIS)

• It is a computer system consists of hardware and software serves as the backbone of an organization's operation
• Gathers and collect data from multiple online systems, analyzes information, and reports the data to aid in the management decision making

Features:

• Flexible

Should allow to analyze and evaluate the data from the multiple sources as needed 

• Easy to use

• Collaborative

Using MIS should facilitate the communication between managers and staff throughout the organization

• Versatile

Should be able to support the different skills and knowledge

Decision Support Systems (DSS)

• It is a computer program application that analyzes the business data and presents it for the users that can make business decision easily
• An informational application 
• May present the information graphically and may include an expert system or artificial intelligence (AI)
• Aimed at business executives or some other group of knowledge workers.
• Example: Process loan application

Characteristics:

• Designed to facilitate decision processes
• Should support automate decision making
• Should be able to respond fast to the changing the need to decision makers

1. Facilitation. DSS facilitate and support specific decision-making activities and/or decision processes.



2. Interaction. DSS are computer-based systems designed for interactive use by decision makers or staff users who control the sequence of interaction and the operations performed.



3. Ancillary. DSS can support decision makers at any level in an organization. They are NOT intended to replace decision makers.



4. Repeated Use. DSS are intended for repeated use. A specific DSS may be used routinely or used as needed for ad hoc decision support tasks.



5. Task-oriented. DSS provide specific capabilities that support one or more tasks related to decision-making, including: intelligence and data analysis; identification and design of alternatives; choice among alternatives; and decision implementation.



6. Identifiable. DSS may be independent systems that collect or replicate data from other information systems OR subsystems of a larger, more integrated information system.



7. Decision Impact. DSS are intended to improve the accuracy, timeliness, quality and overall effectiveness of a specific decision or a set of related decisions.

Expert Systems (ES)

• It is a computer program designed to emulate and mimic the human intelligence, skills or behavior. 
• Developed by using artificial intelligence concepts, tools, and technologies, and possess expert knowledge in a specific field, topic, or skill.

Characteristics:

• Good reliability - must be as reliable as a human expert
• Understandable - able to explain the steps of reasoning while executing. Should have an explanation capability that is similar to the ability of human experts

Network Planning - Proof of Concept

How to design a secured network (methods)

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 policy (rules of the security, example do not change the settings of the computer)
6. Develop the procedure for applying the security policies
7. Develop a technical implementation strategy
8. Train the users, managers, and technical staff
9. Implement the technical strategy and security procedures
10. Test the security and update it if any problems are found
11. Maintain security

The different types of network security designs that will aid good network security
Antivirus and Anti malware Software

• Both of these, antivirus and anti malware can only detect viruses or malware, and then it will removes the threat and fixes the damage.

Application Security

• It is the software to secure the loopholes of our application from the perpetrators. 
• It tracks the procedure of finding our application's vulnerabilities, after then it fixes and preventing them from any cyber attack.
• Uses software, hardware, and processes to keep the assets intact.

Data Loss Prevention (DLP)

• It is a technology, responsible to secure the communication network of an organization.
• To protect the sensitive data.
• Nowadays, employees in an organization are prohibited to upload, forward, or print critical information in an unprotected manner. 

Email Security

• Popular medium to spread threats such as the malware, spams, and phishing attack.
• Social engineering methodologies make these threats appear genuine and sophisticated.
• Email application security is used to secure the access and the data of an email account by blocking the incoming attacks and controls the outbound messages.

Firewalls

• Monitor the incoming and outgoing traffic that are based on a set of predefined rules
• Is a barrier that separates the trusted networks from the untrusted.
• Can be a hardware or a software.

Network Access Control (NAC)

• Strengthen the network by controlling its access,
• By blocking the non compliant endpoint devices, it can save the network from any potential security breaches.

Wireless Security

• It is become another channel for security breaches.
• With wireless security makes it very challenging for any of the unauthorized access to the damage of the data that is stored in any devices.
