Study Notes
Early Developments in Computing
- The first modern computers emerged during WWII, marking a significant technological advancement.
- The Enigma machine was a German cipher device that was decoded by mathematician Alan Turing, aiding in the defeat of U-boats (submarines).
Network Evolution
- ARPANET was developed by Larry Roberts in the late 1960s, laying the foundation for the modern Internet.
- By the late 70s and 80s, computers were frequently subjected to cyber attacks, leading to research on their vulnerabilities.
Computer Security Scope
- Key aspects of computer security include:
- Ensuring availability and accuracy of data.
- Confidently limiting unauthorized data access.
- Engaging personnel at multiple organizational levels.
Security-focused Operating Systems
- MULTICS, created in the mid-60s by General Electric, Bell Labs, and MIT, was the first operating system designed with security as a primary goal.
- UNIX, developed by former MULTICS contributors, primarily focused on text processing.
Internet and Cyber Threats
- By 1990, computer networks became commonplace, representing the early formation of the Internet.
- The Internet age introduced increased threats of cyber attacks, emphasizing the importance of security measures.
Security Implementation Strategies
- Security can be approached through two primary methods:
- Bottom-Up: A grassroots effort often leading to inadequate results.
- Top-Down: Initiatives led by upper management, recognized as more effective.
Layers of Security
- Security is multi-faceted, including:
- Physical, personal, operations, communications, and network security.
- Systems Development Life Cycle (SDLC) is a methodology used for managing security processes.
Traditional SDLC Phases
- The phases of the traditional SDLC include:
- Investigation, Analysis, Logical Design, Physical Design, Implementation, and Maintenance & Change.
Information Security Roles
- Key figures in the information security field include Chief Information Officers (CIOs) and Chief Information Security Officers (CISOs).
- An Information Security Project Team typically comprises:
- Champions, leaders, policy developers, risk assessors, security professionals, systems admins, and end users.
Data Ownership and Responsibilities
- Responsibilities in data management are defined as follows:
- Data Owner: Ensures security and usage integrity.
- Data Custodian: Responsible for storage.
- Data Users: The end users interacting with the data.
Concept of Security
- Security is viewed as both an art and a science:
- Art: Lacks universally accepted rules.
- Science: Driven by technological design.
