Study Notes
Security Principles
- Security measures should be commensurate with the risk and potential harm resulting from unauthorized access or modification of information.
- Administrative controls involve implementing policies and procedures to regulate access, such as access control processes and multi-person operations.
Access Control
- Authentication involves verifying the identity of users or entities through single-factor or multi-factor authentication.
- Authorization grants permission to access system resources based on user roles and responsibilities.
- Logical Access Control Systems validate individual identities and assign access privileges accordingly.
- Mandatory Access Control requires the system to manage access controls according to organizational security policies.
Assets and Objects
- Assets include tangible items like information systems and physical property, as well as intangible assets like intellectual property.
- Objects are information system-related entities that contain or receive information, and access to an object implies access to the information it contains.
Physical Security
- Physical controls involve tangible mechanisms, such as walls, fences, guards, locks, and badge readers connected to door locks.
Principle of Least Privilege
- Users and programs should have only the minimum privileges necessary to complete their tasks to minimize risk.
User Provisioning
- User provisioning involves creating and managing user accounts with approved authorizations.
Network Security
Application Programming Interface (API)
- An API is a set of routines, standards, protocols, and tools for building software applications to access web-based software or web tools.
Data Representation
- A bit is the most essential representation of data (zero or one) at Layer 1 of the Open Systems Interconnection (OSI) model.
- A byte is a unit of digital information that most commonly consists of eight bits.
Cloud Computing
- Cloud computing provides on-demand network access to a shared pool of configurable computing resources with minimal management effort or service provider interaction.
- A community cloud is a cloud infrastructure provisioned for exclusive use by a specific community of consumers with shared concerns.
Access Control Models
- Discretionary Access Control (DAC) allows the owner to determine access rights to an object and what those rights should be.
Encryption
- Encryption protects private information by putting it into a form that can only be read by authorized individuals.
Firewalls
- Firewalls are devices that enforce administrative security policies by filtering incoming traffic based on a set of rules.
Insider Threats
- Insider threats involve entities with authorized access that can harm an information system.
Operating Systems
- iOS is an operating system manufactured by Apple Inc. for mobile devices.
- Linux is an open-source operating system.
Defense Mechanisms
- Layered defense involves using multiple controls arranged in series to protect an asset.
- Social engineering involves tactics to infiltrate systems through email, phone, text, or social media.
Web Security
- A Web Server provides World Wide Web (WWW) services on the Internet.
- Whaling attacks target highly placed officials or private individuals with sizable assets to authorize large fund wire transfers.
Incident Response, Business Continuity, and Disaster Recovery
Incident Response
- Adverse events have negative consequences, such as system crashes, network packet floods, or unauthorized use of system privileges.
Business Continuity
- Business continuity involves actions, processes, and tools to ensure an organization can continue critical operations during a contingency.
- A Business Continuity Plan (BCP) documents predetermined instructions or procedures to sustain business operations during a disruption.
- A Business Impact Analysis (BIA) analyzes an information system's requirements, functions, and interdependencies to determine contingency requirements and priorities.
Security Operations
- A Security Operations Center (SOC) is a centralized function that monitors, detects, and analyzes events to prevent and resolve issues before they disrupt business operations.
Vulnerabilities
- A vulnerability is a weakness in an information system, system security procedures, internal controls, or implementation that could be exploited or triggered by a threat source.
- A Zero Day vulnerability is a previously unknown system vulnerability that can be exploited without detection or prevention.
