Study Notes

Introduction to Information Assurance

Information Assurance (IA) protects information assets from threats like destruction, degradation, manipulation, and exploitation, and outlines recovery methods.
Key aspects of IA include:
- Availability: Ensures timely access to data for authorized users.
- Integrity: Protects information from unauthorized alterations or destruction.
- Confidentiality: Safeguards information from unauthorized disclosure.
- Authentication: Validates the identity of message senders and receivers.
- Non-repudiation: Provides proof of delivery and sender identity to prevent denial of actions.

Categories of Information Assurance

Four major categories include:
- Physical Security: Protects hardware and software from physical threats.
- Personnel Security: Implements measures to prevent misuse of assets by insiders and outsiders.
- IT Security: Encompasses technical features ensuring confidentiality, integrity, and availability of IT infrastructure.
- Operational Security: Establishes protocols for secure user and system interactions.

Proper Practices in Information Assurance

Recommended practices include:
- Enforcing complex passwords.
- Encrypting hard drives.
- Securing sensitive documents.
- Assigning access control based on security clearance.
- Utilizing SSL for secure data transfer.
- Maintaining off-site backups.

Threats and Attacks

Common attacker tactics include:
- Impersonation, spoofing, network attacks, malware, and denial of service attacks.
- Social engineering techniques such as deception and bribery.

Information Warfare (IW)

IW consists of offensive and defensive operations focused on manipulating perceptions and disrupting information flows.
Types of players involved in IW:
- Insiders: Employees or contractors who may exploit their access.
- Hackers: Individuals gaining unauthorized access for various motives.
- Criminals: Target valuable information like bank details.
- Corporations: Seek intelligence on competitors.
- Governments: Acquire sensitive diplomatic and economic information.
- Terrorists: Aim to damage infrastructure or cause casualties.

Levels of Information Assurance

Three distinct levels of IA:
- Physical Level:
  - Involves hardware, telecommunications, and environmental controls.
  - Attacker operations can include physical destruction and eavesdropping.
- Information Infrastructure Level:
  - Focuses on data manipulation in cyberspace, including databases and protocols.
- Perceptual Level:
  - Concerns managing decision-making perceptions, employing social engineering tactics.

IA Functional Components

IA practices are proactive and reactive, focusing on:
- Protection: Safeguarding data and systems.
- Detection: Identifying attacks quickly.
- Restoration: Re-establishing service capabilities.
- Response: Addressing incidents effectively.

Assets in Information Assurance

Assets are valuable resources requiring protection, categorized as:
- Physical Assets: Computers, devices, and personnel.
- Logical Assets: Information and data in various states.
- System Assets: Software, hardware, and administrative resources.
Security solutions are framed using three categories:
- Objects: Items being protected (e.g., files, databases).
- Subjects: Entities requesting access (e.g., users).
- Actions: Operations performed on objects, which must be controlled.
