Study Notes
Physical Devices and Jurisdictions
- Physical devices such as PCs, networks, wires, grids, and routers are located within jurisdictions/authorities, which is important for law enforcement when searching for devices used to run criminal enterprises and cybercrimes.
Cyberspace Layers
- Cyberspace consists of four layers:
- Physical layer: consists of physical devices such as PCs, networks, wires, grids, and routers.
- Logic layer: defines and creates the platform nature of the Internet, built out of components that provide services for users, such as social media, content, shopping, etc.
- Information layer: includes the creation and distribution of information and interaction between users, where users can create and access information, including music, books, videos, and pictures.
- Personal layer: not further described in the provided text.
Information Security
- Information Security is defined as protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction to provide integrity, confidentiality, and availability.
- Information Security includes the broad areas of:
- Information security management
- Computer and data security
- Network security
Cybersecurity
- Cybersecurity is the protection of valuable resources stored and connected to the network, covering human behaviors to technological procedures.
- Cybersecurity domains include:
- Security Engineering
- Framework and Standard
- Data Security
- Software Security
- Component Security
- Connection Security
- System Security
- Human Security
- Organizational Security
- Societal Security
Cybersecurity Domains
- Security Engineering includes:
- Security Architecture
- Access Control
- Cloud Security
- Data Protection
- Network Design
- Secure Application Development
- System Integration
- Cryptography
- Framework and Standard includes:
- Physical Security
- Risk Assessment
- Governance
- Threat Intelligence
- Security Operations
- User Education
- Career Development
Cyberattacks
- A cyberattack is getting access to legitimate systems illegally and establishing control over them to carry out malicious activities.
- Cybersecurity components include:
- Regulating physical access and controlling malicious intrusion.
Cybersecurity Professionals
- Cybersecurity professionals must be informed and flexible to identify and manage potential new threats effectively, such as advanced persistent threats (APTs).
- APTs are attacks by an adversary who possesses sophisticated levels of expertise and significant resources, allowing the attacker to create opportunities to achieve its objectives using multiple attack vectors.
