Study Notes
Fundamentals of Information Assurance (IA) and Information Security (InfoSec)
- Information Assurance (IA) is the practice of assuring information and managing risks associated with the use, processing, storage, and transmission of information.
- IA safeguards the integrity, availability, authenticity, non-repudiation, and confidentiality of user data.
Five Information Assurance Pillars
- Availability: Ensures information is accessible to authorized users when needed.
- Integrity: Protects against improper information modification or damage, ensuring data is trustworthy and accurate.
- Authentication: Determines if a user or system is who they claim to be, providing a secure method for access.
- Confidentiality: Preserves authorized access restrictions, protecting personal privacy and proprietary information.
- Non-repudiation: Provides proof of the origin and integrity of data, making it difficult to deny involvement.
What is Information Security (InfoSec)
- InfoSec defends information from unauthorized access, use, disclosure, and destruction, applicable to all forms of data.
- Comprises two aspects:
- Information assurance ensures data is not lost during critical issues.
- IT security focuses on securing technology from malicious cyber-attacks.
Principles of Security: The CIA Triad
- Confidentiality: Implements rules to limit access, ensuring sensitive information is disclosed only to authorized users.
- Integrity: Guarantees data remains accurate and consistent throughout its life cycle, preventing unauthorized alterations.
- Availability: Ensures assets are accessible to authorized users at necessary times, emphasizing legitimate access against unauthorized threats.
Assets, Attacks, and Threats
- Assets: Valuable information, devices, and systems that require protection to prevent organizational losses.
- Attacks: Actions intended to exploit vulnerabilities to snatch assets, such as data breaches occurring frequently in web-based systems.
- Notable data breach statistic: 80% of victims in India in 2019.
- Types of assets managed under IA include customer data, IT infrastructure, intellectual property, financial data, service availability, and organizational reputation.
Hackers and Crackers
- Hackers: Skilled individuals who either exploit systems for malicious purposes (black hat) or use their skills for good (white hat).
- Crackers: Individuals who break into systems without authorization, often associated with malicious intent.
Tools Used by Attackers
- Protocol Analyzers: Monitor network traffic.
- Port Scanners: Identify open ports for potential access points.
- Vulnerability Scanning Tools: Automate scans to find vulnerabilities within systems.
- Exploit Software: Trigger unforeseen behaviors in systems due to vulnerabilities.
- Password Crackers: Retrieve or access passwords without authorization.
- Keystroke Loggers: Record every keystroke to gather sensitive information.
Security Breaches
- Security breaches violate rules and can lead to asset damage or loss.
- Causes of breaches include:
- Denial of Service (DoS): Disables a machine or network.
- Distributed denial-of-service (DDoS): Floods traffic to prevent legitimate access.
- Unacceptable web browsing practices that lead to vulnerabilities.
Conclusion
- A robust understanding of IA and InfoSec is essential for protecting sensitive data and ensuring the security of information systems against various threats and vulnerabilities.
