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.
