Study Notes

Components of a CBIS

Hardware: Physical parts of the system, such as computers, servers, and peripherals
Software: Programs that instruct the hardware to perform tasks, including operating systems, applications, and databases
Data: Raw facts and figures processed by the CBIS
People: Users and administrators who interact with the system
Procedures: Step-by-step instructions for using the system

Impact of Effective Information Systems

Improved efficiency: Automation of tasks leads to faster processing and fewer errors
Enhanced decision-making: Access to accurate and timely data supports informed choices
Increased productivity: Streamlined processes and improved communication boost overall output
Better customer service: Faster response times and personalized interactions create a positive customer experience

Purpose of Procedures

Standardize system use
Ensure data accuracy and integrity
Prevent unauthorized access
Document decision-making processes

User Authentication

Describes procedures for verifying a user's identity before granting access to system resources
Typically involves username and password combination, but can include multi-factor authentication

Importance of Procedures

Consistency: Ensures everyone follows the same steps
Security: Protects sensitive data from unauthorized access
Accuracy: Reduces errors and maintains data quality
Auditability: Provides a record of actions taken
Compliance: Meets legal and regulatory requirements

Information vs. Data

Data: Raw, unprocessed facts
Information: Processed and organized data that provides meaning and context

Data Accuracy and Completeness in Accounting

Crucial for financial reporting and decision-making
Inaccurate data can lead to errors in financial statements and misleading financial analysis

Knowledge in a Business Context

Knowledge: Understanding and application of information
Expertise: Developed through experience and training
Insights: Patterns and relationships revealed by data analysis

Consequences of Inaccurate Data

Poor decision-making: Leads to wrong choices, potentially impacting profitability and strategy
Missed opportunities: Inaccurate data can obscure valuable insights
Legal issues: Errors in financial reporting can lead to penalties and fines

Value of Information

Competitive advantage: Provides insights into market trends and customer behavior
Operational efficiency: Optimizes internal processes and eliminates waste
Improved risk management: Identifies potential threats and opportunities
Enhanced customer service: Provides personalized recommendations and solutions

Data Backup Procedure

Purpose: To create copies of important data to protect against data loss due to hardware failure, natural disasters, or human error
Frequency: Determined by data sensitivity and risk tolerance

User Authentication Instructions

Username and password requirements: Length, complexity, and character types
Multi-factor authentication methods: Text messages, email codes, security tokens
Account lockout procedures: Number of failed login attempts before account suspension

Additional Authentication Factors

Used to enhance security by requiring multiple forms of verification beyond just a username and password
Examples: biometric authentication, one-time passwords (OTPs), security questions

Importance of Backup Procedure

Ensures data recovery in case of loss or damage
Minimizes downtime and disruption to business operations
Meets legal and regulatory requirements for data retention

Not an Additional Authentication Factor

A generic password manager: A tool for storing and managing multiple passwords

Data Retention Procedure

Objective: To determine how long data should be stored, based on legal, regulatory, and business needs
Compliance: Adherence to industry standards and regulations

Verifying Backup Integrity

Ensures backups are valid and can be used to restore data effectively
Involves testing restoration process by restoring data from backup to a separate system

Backup Media Selection Factors

Storage capacity: Size of data to be backed up
Cost: Budget constraints
Speed: Data transfer rate
Reliability: Durability and resistance to damage

Backup Media Selection Process

Assess data volume and sensitivity: Identify critical data requiring protection
Consider cost and performance factors: Find a balance between budget and data security
Choose appropriate media types: Backup to multiple media for redundancy
Implement data encryption: Protect data from unauthorized access

Data Retention Procedure Component

Policy document: Outlines data retention requirements for different types of data

Indicates that the copyright holder retains all rights to the product or service
Restricts use and distribution without explicit permission

Fair use: Legitimate uses like quoting for review or criticism, teaching, scholarship, and research

License Distribution

Permissions: Terms outlining how users can interact with the product or service
Restrictions: Limits on copying, distribution, or modification

Obtain explicit permission: Contact the copyright holder to request authorization

Password-Protected Website

Suitable medium: Provides secure access control and prevents unauthorized use of copyrighted material
