Study Notes
Attackers and Attacks
- A human or system can launch an attack by exploiting a vulnerability.
- Success of a malicious attack relies on three components: method, opportunity, and motive.
- If any component is denied, the attack will likely fail.
Security Goals
- Confidentiality: Protects sensitive data to ensure only authorized access.
- Integrity: Ensures that data is modified only by authorized personnel or processes, maintaining precision and accuracy.
- Availability: Guarantees that authorized users can access the data when needed.
Computer Security
- The primary aim is to safeguard computer assets: hardware, software, and data.
- Prevents unauthorized data access (confidentiality) and modification (integrity) while ensuring availability.
Controls (Protection Measures)
- Controls or countermeasures block threats from exploiting vulnerabilities.
- Methods to address threats include:
- Prevent: Block the attack or eliminate vulnerabilities.
- Deter: Increase difficulty for attackers but not entirely prevent.
- Deflect: Divert attention to a different, less secure target.
- Mitigate: Reduce the impact of a successful attack.
- Detect: Identify attacks as they occur or afterward.
- Recover: Restore operations after an attack.
Types of Control
- Physical Controls: Utilize tangible methods to thwart attacks.
Vulnerabilities
- Vulnerabilities are weaknesses in systems—procedures, design, or implementation—that could lead to harm or loss.
Threats
- A threat represents a situation with the potential to cause harm to a computing system.
- Understanding threats involves recognizing:
- The possible negative events affecting assets.
- The individuals or factors that could contribute to these events.
Insider Threats
- An insider is anyone granted access or knowledge of an organization's resources.
- Insider threats arise when an authorized individual exploits their access for malicious purposes.
Advanced Persistent Threats (APTs)
- APTs are stealthy, often state-sponsored groups that infiltrate networks, remaining undetected for extended periods with specific objectives.
Data Disclosure Threat
- This threat involves unauthorized sharing of sensitive information, often due to human error, such as misdirected emails or improper data handling.
Alteration and Sabotage Threats
- Alteration Threat: Focused on unauthorized modifications of information or systems.
- Sabotage Threat: Involves deliberate actions to damage an organization's infrastructure, either physically or virtually, including neglect of maintenance and IT procedures.
Harm
- Harm is the negative outcome resulting from an actualized threat affecting valuable assets.
