    Study Notes

    Information Security and Its Importance

    • Information security protects digital information, regardless of its format or location.
    • Confidentiality, integrity, and availability are key principles of information security (CIA Triad).
    • Increased security often leads to reduced user convenience.

    Understanding Threat Actors

    • Script kiddies: Individuals with limited technical knowledge who download automated attack software.
    • Threat actors: Groups or individuals with malicious intent who target information systems.

    Types of Security Vulnerabilities and Attacks

    • Platforms: Weaknesses in hardware or software platforms.
    • Configurations: Improperly configured systems or applications.
    • Third parties: Vulnerabilities introduced by external software providers.
    • Patches: Unsolved security flaws in software, often patched with updates.
    • Zero-day vulnerabilities: Newly discovered flaws that attackers exploit before anyone recognizes them.

    Understanding Attack Vectors

    • An attack vector is the path an attacker uses to penetrate a system, like email, wireless networks, removable media, or social media.

    Social Engineering Attacks

    • Social engineering manipulates vulnerabilities by exploiting individuals' trust and psychological biases.
    • Hoaxes: Spreading false information, often through emails, to manipulate users.
    • Watering hole attacks: Targeting a specific group with malware-infected websites or resources.

    Common Physical Security Procedures

    • Dumpster diving: Searching through trash for valuable data.
    • Tailgating: Following an authorized person through a security door.
    • Shoulder surfing: Observing individuals entering sensitive information, like key codes.

    Impacts of Security Attacks

    • Successful attacks can result in data loss, data exfiltration, data breaches, and identity theft.

    Summary of Key Points

    • Information security is critical for protecting digital data.
    • Threat actors exploit various vulnerabilities, including platform flaws and zero-day exploits.
    • Attack vectors like email, wireless networks, and social media provide avenues for attacks.
    • Social engineering attacks rely on manipulating individuals, often through psychological methods.
    • Attacks can have significant consequences ranging from data loss to identity theft.
