Study Notes

Introduction to Information Security

Information security is a growing concern in today's digital age
Key concepts of information security include:
- Confidentiality: protecting sensitive information from unauthorized access
- Integrity: ensuring the accuracy and completeness of information
- Availability: ensuring that information is accessible when needed

History of Information Security

The history of information security began with computer security during World War II
The need for computer security arose from the need to secure physical locations, hardware, and software from threats
Key events in the development of information security include:
- 1960s: Advanced Research Procurement Agency (ARPA) began examining the feasibility of a redundant networked communications system
- 1970s and 80s: ARPANET grew in popularity, leading to concerns about misuse and the development of security safeguards
- 1973: Robert Metcalfe and David Boggs developed Ethernet, a local area network (LAN) technology

Information Security Concepts

Key terms and critical concepts of information security include:
- Information security: the practice of protecting information and its systems from unauthorized access, use, disclosure, disruption, modification, or destruction
- Information system: a set of interconnected components that collect, process, store, and disseminate information
- Components of an information system:
  - Software
  - Hardware
  - Data
  - People
  - Procedures
  - Networks
Approaches to information security implementation include:
- Bottom-up approach: focusing on individual components and building up to the system as a whole
- Top-down approach: focusing on the system as a whole and breaking it down into individual components
The systems development life cycle includes:
- Investigation
- Analysis
- Logical design
- Physical design
- Implementation
- Maintenance and change
The security systems development cycle includes:
- Investigation
- Analysis
- Logical design
- Physical design
- Implementation
- Maintenance and change

Communities of Interest

Communities of interest are groups of individuals united by similar interests or values within an organization, sharing a common goal of helping the organization meet its objectives
Examples of communities of interest include:
- Information Security Management and Professionals
- Information Technology Management and Professionals
- Organizational Management and Professionals

Information Security Roles

Senior management: responsible for making strategic decisions about information security
Information security project team: responsible for implementing and maintaining information security systems
Data responsibilities: include managing and protecting sensitive data

Information Security: Art or Science?

Security as art: involves implementing security measures in a creative and flexible way, similar to a painter applying oils to canvas
Security as science: involves following a rigorous and systematic approach to implementing security measures

Threats to Information Security

Natural disasters:
- Flood: an overflowing of water onto an area that is normally dry, causing direct damage to all or part of the information system
- Earthquake: a sudden movement of the earth's crust caused by the release of stress accumulated along geologic faults or by volcanic activity
- Lightning: an abrupt, discontinuous natural electric discharge in the atmosphere
- Landslide or mudslide: the downward sliding of a mass of earth and rock
Spoofing: a technique used to gain unauthorized access to computers by forging IP addresses
Man-in-the-middle attack: an attacker monitors or sniffs packets from the network, modifies them, and inserts them back into the network
Spam: unsolicited commercial email
Mail bombing: an e-mail attack where an attacker routes large quantities of e-mail to the target, overwhelming the system.
