Study Notes
Introduction to Information Assurance
- Information Assurance (IA) focuses on protecting information assets from destruction, degradation, manipulation, and exploitation while ensuring recovery options.
- Key aspects needing protection include:
- Availability: Timely access to data for authorized users.
- Integrity: Protection against unauthorized data modification.
- Confidentiality: Ensuring information is not disclosed to unauthorized individuals.
- Authentication: Verifying the validity of transmissions and originators.
- Non-repudiation: Providing proof of data delivery and sender identification.
Major Categories of Information Assurance
- Physical Security: Protecting hardware and software from physical threats.
- Personnel Security: Ongoing measures to prevent unauthorized actions affecting logical and physical assets.
- IT Security: Technical features ensuring confidentiality, integrity, and availability.
- Operational Security: Procedures that govern user interactions with systems for secure operation.
Proper Practices for Information Assurance
- Utilize hard-to-guess passwords and encryption for sensitive data.
- Secure sensitive documents physically and implement staff security clearances.
- Use SSL for secure data transfer, and maintain off-site backups as a recovery measure.
Levels of Focus in Information Assurance
-
Physical Level:
- Involves physical aspects of computing environments and related infrastructure.
- Defenders employ physical security methods to protect from attacks like spying and intrusion.
-
Information Infrastructure Level:
- Encompasses data manipulation in cyberspace and technical measures like encryption and firewalls.
- Defense against impersonation, network attacks, and malware is crucial.
-
Perceptual Level:
- Deals with societal perceptions and decision-making by security personnel.
- Psychological operations such as deception and social engineering are the attackers’ methods, while defenses include screening and education.
Information Warfare
- Offensive part termed "information operations," while defensive strategies are termed Information Assurance.
- Types of Information Warfare (IW):
- Type I: Managing perceptions through deception.
- Type II: Disrupting opponents' information flows.
- Type III: Intelligence gathering by exploiting information systems.
- Offensive players include insiders, hackers, criminals, corporations, governments, and terrorists.
Functional Components of Information Assurance
- IA is proactive (protection and detection) and reactive (restoration and response).
- Environment protection pillars focus on maintaining availability, integrity, authenticity, confidentiality, and non-repudiation.
- Capability restoration relies on established processes for prioritizing essential functions, including backups and redundant systems.
Understanding Assets
- An asset represents what is being protected, including:
- Physical assets: Devices and personnel.
- Logical assets: Information and intellectual property.
- System assets: Software, hardware, and administrative resources.
- Security policies often categorize assets into three types:
- Objects: Items protected (e.g., files, databases).
- Subjects: Entities requesting access to objects (e.g., users).
- Actions: Operations performed on objects (e.g., read, write).
- Security mechanisms manipulate attributes of subjects and objects to maintain overall system security.
