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 is freedom from, or resilience against, potential harm (or other unwanted coercive change) from external forces.
- 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 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
- 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:
- Security and Risk Management
- 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
- Control Types
- Delaying, Preventing, and Detecting
- Due Care and Due Diligence
- Due Care: knowing what the right thing is, then doing what is right
- Due Diligence:
- Asset Security
- Security Architecture and Engineering
- Communication and Network Security
- Identity and Access Management (IAM)
- Security Assessment and Testing
- Security Operations
- 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.
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.
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.
