Study Notes

Introduction to Information Assurance

Information Assurance (IA) protects information assets from destruction, degradation, manipulation, and exploitation while facilitating recovery after incidents.
Core principles of IA include:
- Availability: Ensures timely access to data for authorized users.
- Integrity: Safeguards against unauthorized modifications or destructions of information.
- Confidentiality: Guarantees information is disclosed only to authorized individuals.
- Authentication: Validates the identity of senders, receivers, and the integrity of messages.
- Non-repudiation: Provides proof of data delivery and sender identity, preventing denial of actions.

Categories of Information Assurance

Four major categories include:
- Physical Security: Protects hardware, software, and data from physical threats.
- Personnel Security: Reduces risks of insider threats via clearance and ongoing assessments.
- IT Security: Technical measures for maintaining the system's confidentiality, integrity, and availability.
- Operational Security: Implements procedures to secure interactions between users and system resources.

Proper Practices of Information Assurance

Strategies for effective IA include:
- Enforcing strong passwords and data encryption.
- Securing sensitive documents in safes.
- Assigning security clearances for staff.
- Using SSL for secure data transfers.
- Keeping off-site backups of critical documents.

Levels of Information Assurance

Three distinct levels of focus in IA:
- Physical Level: Involves hardware, networks, and their management.
- Information Infrastructure Level: Covers data manipulation capabilities in cyberspace.
- Perceptual Level (Social Engineering): Manages perceptions influencing security decisions.

Threats and Defense Mechanisms

Attacker Operations include:
- Physical attacks, impersonation, system compromise, malware, denial of service, and psychological manipulation.
Defender Operations involve technical measures like encryption, intrusion detection, and personnel security assessments.

Information Warfare (IW)

IW involves offensive and defensive information operations:
- Type I: Psychological operations influencing opponents' perceptions.
- Type II: Disrupting opponents' information flows.
- Type III: Intelligence gathering from competitors' information systems.

Types of Offensive Players in IW

Insiders: Employees or contractors with access.
Hackers: Unauthorized access for fun or profit.
Criminals: Target valuable information like bank details.
Corporations: Seek competitive intelligence or trade secrets.
Governments: Aim to extract sensitive information.
Terrorists: Cause damage to infrastructure and create chaos.

Information Assurance Functional Components

IA is both proactive and reactive, involving:
- Protection: Safeguarding information assets.
- Detection: Timely identification of attacks.
- Capability Restoration: Procedures for restoring essential functions.
Protection pillars aim to ensure the availability, integrity, authenticity, and confidentiality of information.

Definition of an Asset

An asset is any resource needing protection, including:
- Physical Assets: Hardware and personnel.
- Logical Assets: Information and intellectual property.
- System Assets: Software, data, and communication resources.
Assets possess inherent value, necessitating protective measures.

Security Framework

Security measures classify assets into three categories:
- Objects: Items like documents and databases.
- Subjects: Entities (users/processes) requesting access to objects.
- Actions: Operations performed on objects that must be controlled.
Attributes associated with subjects and objects play a crucial role in security mechanisms and potential vulnerabilities.
