Security Engineering

Security Engineering is a discipline to protect organizational assets with a solution of secure architectural design from being harmed by threats from attackers through vulnerabilities.

  • Security
    • Security is freedom from, or resilience against, potential harm (or other unwanted coercive change) from external forces.
  • Engineering
    • Engineering is the creative application of science, mathematical methods, and empirical evidence to the innovation, design, construction, operation and maintenance of structures, machines, materials, devices, systems, processes, and organizations.
  • Security Engineering
    • Security engineering is a specialized field of engineering that focuses on the security aspects in the design of systems that need to be able to deal robustly with possible sources of disruption, ranging from natural disasters to malicious acts.
  • Design
    • Design is the creation of a plan or convention for the construction of an object, system or measurable human interaction (as in architectural blueprints, engineering drawings, business processes, circuit diagrams, and sewing patterns).



The (ISC)² CBK

The (ISC)² CBK

  • A CBK – sometimes simply called a Body of Knowledge – refers to a peer-developed compendium of what a competent professional in their respective field must know, including the skills, techniques and practices that are routinely employed.1
  • The (ISC)² CBK is a collection of topics relevant to cybersecurity professionals around the world. It establishes a common framework of information security terms and principles which enables cybersecurity and IT/ICT professionals worldwide to discuss, debate and resolve matters pertaining to the profession with a common understanding, taxonomy and lexicon.
  • (ISC)² was established, in part, to aggregate, standardize and maintain the (ISC)² CBK for security professionals worldwide. Domains from the (ISC)² credentials are drawn from various topics within the (ISC)² CBK, which are used to assess a candidate’s level of mastery of the most critical aspects of information security.
  • The (ISC)² CBK is updated annually by the (ISC)² CBK Committee to reflect the most current and relevant topics required to practice the profession.

Certification subject matter

From 15 April 2018, the CISSP curriculum is updated as follows:[10]

  1. Security and Risk Management
    • Fundamentals
      • Clear defined goals
      • Know what to protect: at rest, in transit and while processing
      • Everything must be balanced: business needs vs CIA, accountability, and Assurance
      • Accountability: who did it, non-repudiation and legal consequences
      • Assurance: how do we know if our systems are secure and functioning as intended
    • The CIA Triad
      • Confidentiality
      • Availability
      • Integrity
    • Control Types
      • Physical
      • Technical
      • Administrative
    • Delaying, Preventing, and Detecting
    • Due Care and Due Diligence
      • Due Care: knowing what the right thing is, then doing what is right
      • Due Diligence:
  2. Asset Security
  3. Security Architecture and Engineering
  4. Communication and Network Security
  5. Identity and Access Management (IAM)
  6. Security Assessment and Testing
  7. Security Operations
  8. Software Development Security

From 2015 to early 2018, the CISSP curriculum is divided into eight domains similar to the latest curriculum above.

Before 2015, it covered ten similar domains.

Security Clearance

A security clearance is a status granted to individuals allowing them access to classified information (state or organizational secrets) or to restricted areas, after completion of a thorough background check.

The term “security clearance” is also sometimes used in private organizations that have a formal process to vet employees for access to sensitive information. A clearance by itself is normally not sufficient to gain access; the organization must also determine that the cleared individual needs to know specific information. No one is supposed to be granted automatic access to classified information solely because of rank, position, or a security clearance.

PBA Tools and Techniques

Example Hierarchy from Goals to Business Cases

  • Goals and Objectives
    • Corporate strategies translate goals identified in business plans into actionable plans and objectives.
    • Goals are typically broad-based and may span one or more years. (organization or strategy level, long-term)
    • Objectives, on the other hand, are used to enable goals; these are more specific and tend to be of shorter term than goals, often with duration of 1 year or less. (project or tactical level, short-team/less than 1 year)
    • Objectives describe business value; requirements describe how to achieve it.
  • Problem Analysis
    • the first step of problem analysis is to clarify the need by finding the root cause.
    • the second step is describing the problem or situation so everyone in the organization sees the need in the same way.
    • fishbone & five why
    • Situation Statement
      • a clear, agreed-upon business need is the foundation of the entire project.
      • creating a situation statement is a way to get consensus on the business need.
  • Market Analysis
  • Competitive Analysis
  • Benchmarking
  • Job Analysis
    • used to identity the job requirements and competencies required to perform effectively in a specific job or role
  • Decomposition Model (aka decomposition diagram)
    • Business Analysis: used to identify business analysis tasks, activities, and deliverables by detailing out the business analysis work.
    • Stakeholder Analysis: used to analyze the organization with the goal of discovering stakeholder groups.
    • IT Projects: to break down solutions into solution components to further understand their features.
  • Solution Evaluation Metrics and Acceptance Criteria
    • Business goals and objectives
    • Key Performance Indicators
      • Customer Metrics
      • Sales and Marketing Metrics
      • Operational Metrics
      • Functionality
  • Measurable Acceptance Criteria
    • nonfunctional requirements
    • service-level agreement
  • Evaluation Techniques
    • Surveys and focus group
    • Results from exploratory testing and user acceptance testing
    • Results from day-in-the-life (DITL) testing
    • Results from integration testing
    • Expected vs actual results for functionality
    • Expected vs actual results for nonfunctionality requirements
    • Outcome measurements and financial calculation of benefits

Agile Mindset

Agile Mindset

Agile is a mindset for a high-performance team with commitments to willingly respond or harness changes and continuously deliver valuable products for customer’s satisfaction and competitive advantages through collaboration with them.

A high-performance team is cross-functional and self-organizing. Continuous delivery suggests delivering products iteratively and incrementally; that is, to deliver products with added values in a short timescale frequently or in a sustainable pace.
