    Study Notes

    Principles of Security - 1911194, Topic 2: The Need of Security

    • Learning Objectives: Discuss organizational need for info sec, explain shared responsibility of departments, list/describe threats to info security, and discuss Linux operating systems, distributions, and their use in security.

    Business Need for Security

    • Information security performs four vital functions for organizations:
      • Protecting the organization's ability to function
      • Protecting data and info the organization collects and uses
      • Enabling safe operation of applications running on IT systems
      • Safeguarding technology assets from threats and attacks

    Protecting Functionality of an Organization

    • Organizations need security management, alongside IT departments, to implement and follow security plans.
    • Management is responsible for facilitating security programs.
    • Implementing information security requires strong management, not just technology, and sound management strategies.
    • Security failures disrupt business operations and incur high costs.

    Protecting Collected and Used Data

    • Organizations rely on data to deliver value to customers.
    • Safeguarding data during transmission, processing, and storage is crucial for information security.

    Enabling Safe Application Operation

    • Organizations require environments protecting applications using IT systems.
    • General management oversees operations by different departments, ensuring compliance with security plans coordinated with IT departments. .

    Safeguarding Technological Assets

    • Organizations must use secure hardware and software appropriate for their size and scope.
    • Additional security measures may be needed as the organization grows.
    • General management must continuously supervise and maintain proper infrastructure development; IT coordination is essential.

    Threats and Attacks

    • Key Term (Attack): An intentional or unintentional act compromising information and supporting systems. Attacks can be active or passive, and direct or indirect.

    • Active Attacks: Attacker modifies message content or affects system operations (e.g., changing data streams, creating false statements.) Examples include viruses, worms, and Trojan Horses.

    • Management Reporting: Management needs insights into the types of threats (people, applications, data, info systems, physical assets).

    • Increasing Threats: Despite increasing security, threats and attacks also increase, particularly due to global internet user growth.

    12 Main Threats on Information Security

    • Compromises on intellectual property (IP).
    • Deviation in quality of service.
    • Espionage or trespass (includes hackers, expert hackers, unskilled hackers, crackers.)
    • Forces of nature.
    • Human error or failure (includes disclosing data, erroneous data entry, accidental data deletion, unprotected storage).
    • Information extortion.
    • Sabotage or vandalism.
    • Software attack (Rootkits, Denial of Service -DoS- , distributed Denial of Service -DDoS).
    • Technical hardware failure or error.
    • Technological obsolescence.
    • Theft and physical attacks.

    Defense in Depth (DiD)

    • Defense in Depth is an information security approach with layered security mechanisms, protecting confidentiality, integrity, and availability of networks and data within the system.

    Linux Operating System

    • Linux is a modular Unix-like operating system, based on principles from the 1970s and 1980s.

    • It's open-source so users can create their own distributions.

    • Examples of well known Linux Distributions include: Ubuntu, Fedora, Linux Mint, Debian, Kali Linux, and CSI Linux.

    • Different Distributions are focused on different functional uses from ethical hacking to digital forensics.

    • Web sites such as www.Linux.org and www.Kali.org offer relevant information and support.
