Overview of risk management

Information Assurance and Security Models

CIA Triad (Confidentiality, Integrity, Availability)
Committee on National Security Systems (CNSS) McCumber Cube
Business Model for Information Security (BMIS)
A Reference Model for Information Assurance & Security (RMIAS)

IA vs InfoSec

IA is a process/model that includes infoSec elements
Both involve people, processes, techniques, technology (administrative, technical, physical controls)
InfoSec focuses on CIA triad (confidentiality, integrity, availability)
IA includes reliability, access control, non-repudiation, strategic risk management
ISMS are closely aligned with IA

Security Paradigm

Principle 1: Hacker likely someone known
Principle 2: Trust no one
Principle 3: Make the hacker believe they'll be caught
Principle 4: Protect in layers
Principle 5: Plan for complete failure in a single layer
Principle 6: Make security part of the initial design
Principle 7: Disable unneeded services
Principle 8: Understand & secure before connecting
Principle 9: Prepare for the worst

Risk Treatment

Risk Avoidance
Risk Transfer
Risk Reduction
Risk Retention
Risk Assessment
Risk Treatment Options

IA Core Principles

Confidentiality – disclosure to authorized users
Integrity – original intended form
Availability – ready for use within stated parameters
Possession – remains in custody of authorized personnel
Authenticity – conforms to reality
Utility – fit for a purpose
Privacy – protection of personal information
Authorized Use – available only to authorized personnel
Nonrepudiation – ensure the originator of a message cannot deny action

IA Architecture Framework

IA root driver is Risk
IA drivers include business drivers, technical drivers
Perspectives include People, Policy, Business process, Systems & Application, Information/data, Infrastructure
This describes an IA architecture

Information Assurance Process

Enumeration & Classification of data/information assets
Value, state, location, sensitivity, form for evaluating assets
Assessing vulnerabilities and threats
Analyzing probability and impact of risks
Managing risks through treatment and systems

Information Assurance Model

IA tools are dedicated to defending key elements
- People – training, ethics, culture, education, motivation
- Process – procedures, rules, standards, security guidelines
- Technology – tools to mitigate attacks (firewalls, anti-viruses, encryption)

Risk Treatment Decision Making Process

Steps in the process: Risk Assessment, Risk Assessment Results, Risk Treatment Options, Risk Avoidance, Risk Transfer, Risk Reduction, Risk Retention, Risks Acceptable, and Risk Acceptance
The risk model is based on ISO/IEC 27005:2008 standards

Risk Treatment Options

Risk Avoidance - avoiding actions that may lead to risk.
Risk Transfer - shifting risk from one party to another (contractually).
Risk Reduction - measures to decrease the risk
Risk Retention – accepting risks

Points to Note

IA requires integration from inception
Weak link in security is often the human element
Holistic security includes people, organization, governance, processes, and technology
Security programs should prevent trouble.
Implementing firewalls isn't enough; operational issues need attention.
Risk management balances cost and risk.

Additional Information

Information is data endowed with meaning and purpose
IA is the degree of confidence that security features, practices, procedures, and architecture meet policy
Security is about asset protection, including elements of deterrence, avoidance and prevention, detection, recovery, correction
