Study Notes
Importance of IT Security
- Essential for the functionality of modern societies.
- Threats to information security come from various actors with different consequences.
- Information is central to IT security, encompassing threat situations, vulnerabilities, successful attacks, and internal security status.
Security Goals
- Confidentiality: Ensures data is accessible only to authorized individuals.
- Integrity: Guarantees that data remains unaltered and identifies any modifications.
- Availability: Ensures that data and services are operational and accessible.
- Non-Repudiation: Confirms that the sender or author cannot deny their ownership of the data.
Key Roles in IT Security
- White Hat Hackers: Skilled individuals who bypass security measures with benign intent or technical curiosity.
- Black Hat Hackers: Malicious individuals who breach security for personal gain, reputation, or to inflict harm.
- Script Kiddies: Inexperienced individuals who use existing software scripts to exploit vulnerabilities without deep understanding.
Consequences of Security Incidents
-
Data-related consequences:
- Unauthorized access leading to exposure of sensitive information and use for further attacks.
- Data manipulation, such as encryption to deny access.
- Data deletion impacting the availability of information and services.
-
Service-related consequences:
- Disruption of service operations, affecting community processes.
- Influence on processes outside the directly impacted systems.
- Malfunctions that cause further damage to infrastructures.
Broader Implications of Attacks
- Ransom Extortion: Demands for money to restore stolen data or cease attacks.
- Industrial Espionage: Illegally obtained information is used for competitive advantages.
- System Compromises: Attacks on additional systems are facilitated by stolen information and access.
- Backdoors: Allow attackers ongoing access to compromised systems.
Challenges in Attack Attribution
- Difficulty in tracing an attack to a specific actor.
- Attacks often originate from compromised computers already controlled by hackers.
- Attackers may mislead investigations through decoys, such as foreign language comments or timing of attacks.
- Reliable attribution is crucial for public accusations and responses to attacks.
- Systematic collection of relevant information is vital for preventing, detecting, and countering attacks.
