    Study Notes

    Risk Management

    • Risk management involves understanding your organization's information assets (knowing yourself) and the threats facing it (knowing the enemy).

    Attack Surface

    • The attack surface is the sum of all potential entry points that a threat agent can use to gain unauthorized access to an organization's information assets.

    Residual Risk

    • Residual risk is the risk that remains after controls have been implemented.

    Risk Identification

    • Self-examination is crucial for risk identification.

    • Prioritize your information assets based on their importance:

      • People
      • Procedures
      • Data and information
      • Software
      • Hardware
      • Networking elements

    Identifying Hardware, Software, and Network Assets

    • Track key attributes:
      • Name
      • IP address
      • MAC address
      • Asset type
      • Serial number
      • Manufacturer name
      • Manufacturer's model
      • Software version
      • Physical location
      • Logical location
      • Controlling entity

    Identifying People, Procedures, and Data Assets

    • Assign responsibility to managers with appropriate knowledge and experience.

    • Record information using a reliable system.

    • Track key attributes:

      • People:
        • Position
        • Supervisor
        • Security clearance
        • Special skills
      • Procedures:
        • Description
        • Intended purpose
        • Associated software, hardware, and networking elements
        • Storage locations
      • Data:
        • Owner
        • Size
        • Data structure
        • Online or offline status
        • Location
        • Backup procedures

    Data Classification Model

    • Different data classification levels can be applied:

      • Public
      • For official use only
      • Sensitive
      • Classified
    • The U.S. Military uses these classifications:

      • Unclassified data
      • Sensitive but unclassified (SBU) data
      • Confidential data
      • Secret data
      • Top Secret data

    Assessing Values for Information Assets

    • Assign relative values to information assets based on factors like:
      • Criticality to organization's success
      • Revenue generation
      • Profitability
      • Replacement cost
      • Protection cost
      • Potential for embarrassment or liability

    Identifying and Prioritizing Threats and Threat Agents

    • Each threat requires specific controls.

    • Conduct a threat assessment:

      • Determine the potential impact of each threat on the targeted information asset.

    Threats

    • Back doors
    • Brute force
    • Dictionary
    • Man-in-the-middle
    • Password crack
    • Social engineering
    • Phishing
      • Spear phishing
      • Vishing

    Threat Categories

    • Internal threats: Employees, contractors, and insiders.
    • External threats: Hackers, competitors, cybercriminals, and foreign governments.
    • Natural threats: Storms, floods, earthquakes, and fires.
    • Accidental threats: Human errors, equipment malfunctions, and system failures.

    Vulnerability Assessment

    • Review each information asset for potential threats.

    • Create a list of vulnerabilities:

      • Specific avenues that threat agents can exploit.

    Threat-Vulnerability-Asset (TVA) Worksheet

    • Combine lists of assets, vulnerabilities, and threats into a single worksheet.

    Determining Loss Frequency

    • Assesses the likelihood of an attack and its probability of success.

    • Assign a numeric value to likelihood based on industry reports and historical data.

    • Estimate the quantitative value of the likelihood of a successful attack.

    Evaluating Loss Magnitude

    • Determine the amount of information asset potentially lost in a successful attack.

    • Consider the value of the information asset and the potential impact of a loss.

    Calculating Residual Risk

    • Formula: Risk = (Loss Frequency * Loss Magnitude) – (Percentage of Risk Mitigated by Current Controls) + Measurement Uncertainty

    Example Risk Calculation

    • Scenario: An ecommerce database with a 10% chance of attack, a 50% chance of a successful attack, a value of 50, and a 80% compromise rate.

    • Calculation:

      • Loss Frequency = 0.1 * 0.5 = 0.05
      • Loss Magnitude = 0.8 * 50 = 40
      • Risk = 0.05 * 40 + 0.25 = 2.5
