    Study Notes

    Information Security Challenges

    • Securing information is not a simple task because of the constant change and evolution of security threats and attacks.
    • Smartphones are commonly the target of attacks.

    Difficulties Faced in Defending Against Attacks

    • Attacks are continuously increasing in speed and sophistication.
    • Attacks are easier to launch due to the availability of readily accessible attack tools.
    • Vulnerabilities are discovered faster by attackers.
    • There are delays in releasing security patches.
    • The distribution and effectiveness of security patches can be weak.
    • Attacks are dispersed through various sources making them harder to stop.
    • Users are often confused about important security measures, which can affect system security.
    • The Slammer worm infected 75,000 computers within 11 minutes of its release.
    • The Slammer worm's infection rate doubled every 8.5 seconds.
    • The Slammer worm scanned 55 million computers per second.

    Importance of Information Security

    • Preventing data theft - protecting business and individual data.
    • Thwarting identity theft - preventing unauthorized use of personal information for financial gain.
    • Avoiding legal consequences - adhering to laws protecting electronic data privacy, such as HIPAA and PCI DSS standards.

    Types of Attackers

    • Insiders - Individuals within an organization who can pose a threat to data security.
      • Examples of insider attacks include leaking sensitive data, planting malicious code, and concealing financial losses.
    • Cybercriminals - Highly motivated individuals who engage in cybercrime for financial gain.
      • Cybercriminals are well-funded, tenacious, and willing to take risks.
      • Cybercrime often involves targeted attacks against financial networks, unauthorized access to information, and theft of personal information.
      • Examples of cybercrime include trafficking in stolen credit cards and financial information, and committing fraud through spam.
    • Cyberterrorists - Individuals motivated by ideology who engage in cyberterrorism to spread misinformation, propaganda, and disrupt essential services.
      • Cyberterrorist attacks often involve defacing electronic information, denying service to legitimate users, and compromising vital data.

    Steps of a Typical Attack

    • Probe for Information: Attackers gather information about a system's hardware, software, and network connections to identify vulnerabilities.
      • Examples of probing techniques include ping sweeps, port scanning, and querying for information.
    • Penetrate Defenses: Attackers breach security measures through methods like cracking passwords.
    • Modify Security Settings: Attackers alter security settings to gain easy and persistent access to compromised systems.
    • Circulate to Other Systems: Attackers use compromised systems or networks as a base to target other systems.
    • Paralyze Networks and Devices: Attackers aim to disable infected computers or networks by damaging critical files or injecting malicious software.

    Five Fundamental Security Principles

    • Layering: Creating multiple security layers that work together to protect information.
    • Limiting: Restricting access to information to only those who need it and limiting the scope of that access.
    • Diversity: Utilizing different security products and methods to provide multiple lines of defense.
    • Obscurity: Concealing details about a system's configuration from potential attackers to make it harder to exploit vulnerabilities.
    • Simplicity: Designing security measures that are user-friendly and easy to understand.
