    Study Notes

    Security Problems

    • Cybersecurity awareness among employees is often lacking, leading to security challenges.
    • Security attack techniques are evolving and becoming more sophisticated.
    • Increased number of insecure network devices, such as mobile gadgets and IoT devices.
    • Common security issues include misconfigurations of systems and applications.

    Computer Security Concepts

    • Computer security involves protecting automated information systems to maintain integrity, availability, and confidentiality of resources like hardware, software, and data.

    Vulnerabilities, Threats, and Attacks

    • Platforms with vulnerabilities include:

      • On-Premises Platforms: Security concerns arise from inadequate configurations and numerous external entry points like USB drives and email.
      • Cloud Platforms: Vulnerabilities often stem from misconfigurations and constant exposure to threats due to remote accessibility.

    • Configuration Vulnerabilities: Weak configurations arise from improperly implemented security settings and delays in applying patches to firmware or software.

    • Zero-Day Vulnerabilities: Exploited by attackers before discovery, these are highly dangerous due to the absence of available patches.

    • Threats are potential damaging events, with cybersecurity threats exploiting existing vulnerabilities. Examples include unauthorized server access, ransomware, and Denial of Service (DoS) attacks.

    • Threat Actors: Individuals or entities responsible for cyber incidents, targeting users, enterprises, and governments. Categories include script kiddies, hacktivists, state actors, and insiders.

    • Types of Attacks:

      • Passive Attacks: Focus on gathering information without altering system resources.
      • Active Attacks: Aim to modify system resources or disrupt operations, with categories including fabrication, modification, and interruption.

    • Attack Vectors: Pathways used by threat actors to breach systems. Common vectors include:

      • Email: Main delivery method for malware, often through deceptive attachments or links.
      • Wireless: Vulnerable to interception if not adequately protected.
      • Supply Chain: Risk of malware insertion during production and storage phases.
    • The financial impact of cybercrime is continually rising, with costs expected to escalate further.
    • Cyber attacks are projected to persist indefinitely, posing ongoing threats to organizations.
    • Live cyber attack maps provide real-time visualization of ongoing threats and incidents.
