    Study Notes

    The Birth of the Internet

    • The U.S. Department of Defense’s Advanced Research Projects Agency (ARPA) initiated the ARPANET project in 1968, which led to the development of the internet.
    • ARPANET was designed to create a redundant, networked communications system for military information exchange.
    • Dr. Larry Roberts, who spearheaded the ARPANET project, developed the program plan that ultimately led to the internet.

    Information Security Threats

    • Hackers can purposefully threaten unprotected information systems by engaging in acts of trespass or espionage.
    • Natural disasters like severe storms can incidentally threaten buildings and their contents due to acts of God or nature.

    Vulnerabilities in Information Systems

    • Vulnerabilities are weaknesses in assets or their defensive systems.
    • Examples include software flaws, unprotected system ports, and unlocked doors.
    • Some vulnerabilities are documented and published, while others remain undiscovered.

    The C.I.A. Triad: Critical Characteristics of Information

    • Confidentiality: Only authorized individuals and systems should have access to information.
    • When confidentiality is breached, unauthorized access occurs.
    • Integrity: Information should be complete, whole, and uncorrupted.
    • Integrity is threatened by corruption, damage, destruction, or disruptions to its authentic state.
    • Integrity can be compromised during storage or transmission.
    • File hashing is used to ensure information integrity by generating a unique hash value for each file.
    • Availability: Data should be accessible when needed.
    • The value of information can be affected by its availability.
    • Information is considered to have availability if it is accessible in the expected format for use.
    • Utility: Information should have value and usefulness for its intended purpose.
    • Data's value and usefulness may vary depending on its interpretation.
    • Possession: Information ownership and control should be legitimate and authorized.

    Information Security and Organizations

    • Information security programs require a wide range of professionals.
    • Organizations must balance accessibility with security.
    • Information security is an on-going process, not a goal.
    • Striking a balance between user needs and security requires careful consideration of various voices within an organization.
    • Excessive focus on security can undermine end-user needs.
    • An information security program can be too entrenched in system management and protection.
