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.
