Study Notes
Critical Characteristics of Information
- C.I.A defines the core characteristics: Confidentiality, Integrity, Availability.
- Additional characteristics include Accuracy, Authenticity, Utility, and Possession.
Confidentiality
- Prevents unauthorized disclosure of sensitive information (e.g., credit card details, personal identifiable information (PII), health records).
Integrity
- Ensures information is accurate, complete, and authorized.
- Vulnerable to threats like corruption or unauthorized changes.
Availability
- Ensures authorized users can access information when needed without obstruction.
- Critical for maintaining data in correct formats and locations.
Accuracy
- Information must be free from errors and meet user expectations.
- Any alteration leading to a mismatch changes its status from accurate to inaccurate.
Authenticity
- Indicates that information is genuine and has not been altered.
- Authentic information retains its original state throughout its lifecycle.
Utility
- Information has value only when relevant and usable for specific purposes.
- Format must be meaningful to the end user for maximum effectiveness.
Possession
- Relates to ownership or control of information.
- Information is considered possessed once accessed, regardless of its format.
Breaches
- A breach of confidentiality automatically leads to a breach of ownership.
- Conversely, a breach of ownership does not necessarily compromise confidentiality.
McCumber Cube
- Visual model representing interconnections among information security factors.
- Layers include security goals (C.I.A), security measures/controls, and information states (Storage, Transmission, Processing).
Components of an Information System
- Software: Key component, often vulnerable due to bugs; security is frequently overlooked during implementation.
- Hardware: Physical technology crucial for executing software and storing data; traditional security methods include locks and biometrics.
- Data: Most valuable asset targeted by cyber attacks; its integrity must be maintained.
- People: Users can pose threats; education and training are essential for security.
- Procedures: Written guidelines direct the use of systems; unauthorized access to these can jeopardize data integrity.
System Development Life Cycle (SDLC)
- Involves detailed analysis, planning, design, implementation, and support phases.
- Focuses on developing a reliable information system through structured procedures.
Security System Development Life Cycle (SecSDLC)
- An adaptation of SDLC that incorporates security considerations at every phase.
- Planning and Analysis: Assesses potential impacts of security breaches; includes preliminary risk assessments.
- Design: Involves security functionalities and planning to address weaknesses.
- Implementation: Focuses on system integration with chosen security controls.
- Support: Ensures ongoing security post-implementation through monitoring and updates.
Importance of SecSDLC
- Proactively identifies potential threats and establishes countermeasures.
- Ensures that all security aspects align with the organization's information security goals.
