Study Notes
Basic Security Concepts—Countermeasures
- Course: ITBP301, taught by Ali Ismail Awad & Norziana Jamil at UAEU.
- Focus on fundamental security concepts, vulnerabilities, and countermeasures against threats.
Learning Objectives
- Identify assets requiring protection.
- Understand potential threats to these assets.
- Explore countermeasures to mitigate threats.
Information Security vs. Cybersecurity
- Cybersecurity encompasses a broader scope:
- Includes information/data security, device security, network security, and people.
- All connected devices fall within cyberspace.
Information Security: Overview
- Merges technical implementation with management strategies.
- Emphasizes the necessity for governance and decision-making processes.
Historical Overview
- Key aspects of security have included access control and privacy.
- Historical practices like secret messages show the evolution of security measures.
Security Definition
- Core model: CIA (Confidentiality, Integrity, Availability)
- Confidentiality: Prevent unauthorized disclosure of information.
- Integrity: Ensure only authorized modifications occur to information.
- Availability: Guarantee timely access to information for authorized users.
CIA Security Concepts
- Confidentiality: Involves proper information access restrictions and privacy protections.
- Integrity: Protects against unauthorized modifications, ensuring authenticity and non-repudiation.
- Availability: Focuses on reliable and timely access to information.
Security Risks
- Mitigating risks necessitates:
- Understanding potential threats.
- Recognizing the origins of system vulnerabilities.
- Utilizing mechanisms to reduce or eliminate threats.
Vulnerabilities, Threats, and Attacks
-
Vulnerabilities types:
- Corrupted (loss of integrity).
- Leaky (loss of confidentiality).
- Unavailable or slow (loss of availability).
-
Threats:
- Possibilities of exploiting vulnerabilities, posing security risks to assets.
-
Attacks:
- Passive attacks: Do not affect resources, classified as eavesdropping or traffic analysis.
- Active attacks: Attempt to alter resources, can be executed by insiders or outsiders.
Passive vs. Active Attacks
-
Passive Attacks:
- Aim to obtain information without affecting system resources, making them hard to detect.
- Types include content release and traffic analysis.
-
Active Attacks:
- Actively attempt to disrupt or manipulate system resources.
Practical Application
- In-class exercises focus on identifying scenarios where confidentiality, integrity, or availability is compromised.
