what is risk
What is risk?
  • No universally recognized “Definition”
  • The exposure/potential/possibility to suffer some loss of an asset
  • What about likelihood and impact?
  • Can be qualitative or quantitative
  • The most important concept:
    • When talking about “risk”, make sure you agree on what definition you are using!

what do we have to measure
Threats

Likelihood

Impact

Vulnerabilities

Controls Effectiveness

Threat Assessment and Threat Matrix

What do we have to measure?

Vulnerability Assessment

Controls Assessment

The Risk Equation is Simple. Obtaining the Correct Values is Not

asset identification
Asset Identification
  • What are the assets within an organization?
    • Systems, buildings, cars, people, products
    • Business processes, applications, data
  • How and who determines the assets?
    • Commissioning, asset management, purchasing records, DHCP records, Active Directory
  • How often are the assets identified?

Lucent Technologies – CALA RoadShow 2005

asset ownership and management
Asset Ownership and Management
  • Asset owner is usually the system administrator or someone from the support organization
  • Should be a business unit representative:
    • Someone who can identify the data on the system
    • Someone who determine the users of the system
    • Someone who understands the data flow (inbound and outbound)

Lucent Technologies – CALA RoadShow 2005

risk speak
Risk Speak
  • So many terms with so many equally valid definitions:
    • Threat Agent
    • Threat Catalyst
    • Inhibitors / Amplifiers
    • Catalyst
    • Capability
    • Motivation
    • And More!

traditional risk management
Traditional Risk Management
  • Mitigate all risks to effectively reduce risk to ZERO
    • Risk > 0 Becomes Unacceptable
  • Extremely costly
  • Slow to mitigate the risks
  • Generally shuts the business down.
    • How do you remove the risk of a production system

risk management as an enabler
Risk Management as an Enabler
  • Allows a business to measure the level of risk that they are “comfortable with”
  • Drive to mitigate risks to below the acceptable level, not zero
  • Acceptable level of risk may be by asset, physical location of device, corporate posture, etc.
  • Business enabler

acceptable levels of risk factors
Acceptable Levels of Risk Factors
  • How does a company determine their acceptable level of risk?
    • Organization Risk Tolerance: Is the company a former brick & mortar type firm with a conservative approach or a progressive Silicon Valley firm looking to be the first to market?
    • Personnel Tolerance: Individuals within the organization will affect the tolerance levels
    • Reaction to Previous Events: What were the results of any previous compromises/intrusions/breaches?
    • Policy, Regulations, Legal Issues: These may determine what level of risk a company can deal with
    • Risk Scope: An organization may be focused on a particular system, but need to be aware of additional connectivity issues

Lucent Technologies – CALA RoadShow 2005

advantages of acceptable risk
Advantages of “Acceptable Risk”
  • Truly serves as a business enabler
    • This is redefines the concept of “business vs security”
  • Competitive Advantage?
    • Absolutely! Get services to market first!
  • Focus on fixing the risks that you have to address
  • May maintain various levels of acceptable risk
    • Logical & Physical Location, Scope, Connectivity, Customer Base and usage

risk management
Risk Management
  • What stays the same?
    • Still need a Risk Management Program
    • Still need to know what the assets are
    • Still need to have some type of risk assessment methodology
    • Still need a risk management organization
    • Still need to agree on a measurement mechanism
      • Quantitative or Qualitative
    • Risk Measurement is not a one-off effort
      • Trigger points should initiate risk analysis at potential risk value change points during the asset lifecycle
    • Still need to mitigate the risk

Lucent Technologies – CALA RoadShow 2005

risk management lifecycle
Risk Management Lifecycle

Lucent Technologies – CALA RoadShow 2005

risk management program plan
Risk Management Program Plan
  • Develop a “Risk Management Program Plan”
    • Defines the overall structure and program of the risk management efforts of the organization
    • Describes the organizational structure, roles and responsibilities of the members
    • Provides metrics, governance, compliance issues, reporting mechanisms, etc.
    • Should place a “Risk Management Director/Officer” with the overall Corporate level responsibility
      • manages the risk management organization and activities
    • Database may be used to support the Program

Lucent Technologies – CALA RoadShow 2005

risk database
Risk Database
  • Maintains Threats, Vulnerabilities, Controls, Likelihood, Impacts
  • Can be utilized for Quantitative and Qualitative efforts
  • Can prompt for periodic assessment reminders
  • Integrate with, or be, the Asset Database
  • Can be used to provide Enterprise Risk Management functions including:
    • Dashboard
    • Tiered and Segmented Reporting
  • Is extremely valuable to malicious individuals and must be protected accordingly
  • Supports compliance and governance matters

Lucent Technologies – CALA RoadShow 2005

trigger points
Trigger Points
  • You can’t just measure the risk of an asset every year or two. Certain changes must trigger a risk measurement of the asset.
  • A “Trigger Point” is a Risk Management program call that is inserted into other operations and programs to ensure that Risk Management is considered as part of certain programs and at the appropriate times.
    • Business Impact Analysis
    • Change Management
    • Acquisitions
    • System Commissioning or Decomissioning

Lucent Technologies – CALA RoadShow 2005

risk methodologies
Risk Methodologies
  • Many different types. Some fit better in particular companies or industries than others.
    • OCTAVE: Operationally Critical Threat, Asset, and Vulnerability Evaluation (http://www.cert.org/octave/)
    • SPRINT, SARA, FIRM (http://www.securityforum.org)
    • CRAMM (http://www.cramm.com/)
    • RiskWatch, COBRA, and many others
  • Choose the one that works the best for you.
    • Industry / Business Sector – Some tools work better than others
    • Collateral Support - Including tools and training availability
    • Industry Support – Who recognizes which methodologies

Lucent Technologies – CALA RoadShow 2005

risk management what must change
Risk Management – What Must Change
  • Modifications of the existing risk management program:
    • Ensure that acceptable risk doesn’t slide below an agreed upon threshold
    • Security analysts need to business and operations savvy to understand business drivers
    • Continuously monitor external resources such as new regulations, technologies, and what the competition is doing
    • Process to determine whether to continue to mitigate further below “Acceptable Risk” or to move on

Lucent Technologies – CALA RoadShow 2005

summary
Summary
  • Know Your Assets!
  • Devote the required resources
  • Determine your “Acceptable Level of Risk”
    • Use a consistent measurement unit
      • Your “Medium” may not be somebody else’s “5”
    • Determine the scope of the Acceptable Level
      • Is it for all assets or particular assets
    • Measure the level of risk
