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.
