Study Notes

Information Security Overview

Downtime refers to periods when a system is unavailable, affecting financial performance, revenue, reputation, and incurring other expenses.
Cybersecurity involves prevention, detection, and response to cyberattacks, which can impact individuals, organizations, and nations.
Cyberattacks are malicious attempts to access or harm computer systems.

Types of Cyber Threats

Hackers use their technical expertise to break into systems for profit or challenge.
Malware includes any software designed to damage or disable systems.
Drive-by hacking targets unsecured wireless networks for unauthorized access.
Botnets refer to networks of infected devices controlled by a hacker.

Authentication and Authorization

Authorization grants users permission and access levels within a system.
Three categories of authentication:
- Something the user knows (e.g., passwords).
- Something the user has (e.g., smart cards, tokens).
- Something that is part of the user (e.g., biometrics like fingerprints or voiceprints).
Voiceprints are unique measurable characteristics of a voice but can be costly and intrusive.

Security Strategies and Impact Analysis

Single-factor authentication relies solely on user ID and passwords.
Business Impact Analysis identifies critical functions and potential disaster effects.
Technology recovery strategies prioritize restoring hardware, software, and data post-disruption.

Agile MIS Infrastructure Characteristics

Accessibility, availability, maintainability, portability, reliability, and scalability are essential attributes for an effective MIS.

Blockchain and Distributed Ledger Technology

Blockchain is a tamper-proof distributed ledger technology.
Advantages include immutability, digital trust, and integration with the Internet of Things.
Proof-of-work refers to computational challenges to add transactions to the blockchain.
Bitcoin operates independently of central banks; Ethereum offers smart contract capabilities.

Connectivity Fundamentals

Networks enhance communication and sharing resources.
Types of networks:
- Local Area Network (LAN): connects devices in close proximity.
- Wide Area Network (WAN): spans large geographic areas.
- Metropolitan Area Network (MAN): typically covers a city.
Mobile technology allows users to access information on portable devices.

Wireless Communication

Wi-Fi enables wireless connections between devices via radio waves, supported by infrastructure like transmitters and access points.
Key wireless performance metrics include bandwidth (data transfer capabilities) and bit rate (data per unit time), measured in kilobits (Kb), megabits (Mb), and gigabits (Gb).

Personal Area Networks

Personal Area Networks (PANs) facilitate short-distance communication for devices owned by a single user.
Bluetooth technology is commonly used for wireless communication between devices over short distances.
