Study Notes

Malware and Attacks

Trojan's main purpose is to provide unauthorized access to the system.
Ransomware is often delivered to victims through malicious email attachments.
Logic bomb is a type of malicious code that is triggered by a specific event or condition.
Phishing attacks aim to steal sensitive information.

Malware Types

Virus is a type of malware that replicates itself and spreads to other systems.
Trojan is designed to appear as a legitimate program but performs malicious actions.
Malware can be delivered to victims through malicious email attachments, social engineering, exploit kits, or all of the above.

Cybersecurity Concepts

Service Level Agreement (SLA) is a formal agreement between two parties.
Data integrity and confidentiality aim to protect sensitive data from unauthorized access or disclosure.
Information recording is important in organizations to ensure compliance with data protection laws and regulations.

CIA Triad

Confidentiality refers to protecting data from unauthorized access.
Integrity refers to maintaining the accuracy and completeness of data.
Availability refers to ensuring that data is accessible when needed.

Attacks and Security Roles

A Denial of Service (DoS) attack is where an attacker floods a network with traffic to disrupt normal operations.
A Security Analyst in a Security Operations Center (SOC) monitors network traffic and detects security incidents.
A worm is a type of malware that spreads on its own, while a virus requires human interaction to spread.

Cryptography and Vulnerabilities

Public Key Infrastructure (PKI) is a framework that manages digital certificates and keys for secure communication.
A zero-day vulnerability is unknown to the public, while a known vulnerability is known to the public.
A Data Protection Officer (DPO) ensures compliance with data protection laws and regulations.
