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.
