Study Notes
Vulnerabilities
- A vulnerability is a weakness in a system that can be exploited.
- Software vulnerabilities arise from coding errors (e.g., buffer overflows) or outdated software.
- Hardware vulnerabilities can be caused by bugs in the firmware or insufficient physical protection.
- Network vulnerabilities include weak encryption protocols and unsecured open ports.
- Human vulnerabilities stem from social engineering (manipulating people to disclose information) and insider threats (employees or contractors with malicious intent).
Threats
- A threat is a potential danger that exploits a vulnerability, jeopardizing information security.
- Types of threats include malware (viruses, worms, Trojans, and ransomware), network threats (DoS attacks and MitM attacks), and social engineering threats (phishing and pretexting).
Threat Actors
- Hackers: Black hat hackers (malicious) vs. white hat hackers (ethical).
- Criminal organizations: Engage in cybercrime for financial gain.
- State-sponsored actors: Government entities conducting cyber espionage or sabotage.
Attacks
- An attack is an intentional act that exploits a vulnerability to damage or disrupt a system.
- Common techniques include vulnerability exploitation, phishing attacks, SQL injection, and cross-site scripting (XSS).
- Stages of an attack include reconnaissance, scanning, gaining access, maintaining access, and covering tracks.
Consequences of Attacks
- Data breaches: Unauthorized access to sensitive data leading to identity theft, financial loss, and reputational damage.
- Financial Loss: Direct and indirect costs related to recovery, legal fees, fines, and loss of customer trust.
- Operational Disruption: Deterioration of business operations and customer satisfaction due to downtime and service interruptions.
