    Study Notes

    Reasons for Security Break

    Human Error

    • Carelessness: e.g., using weak passwords, falling for phishing scams
    • Lack of knowledge: e.g., not understanding security best practices, misconfiguring systems
    • Negligence: e.g., failing to update software, ignoring security warnings

    Social Engineering

    • Phishing: tricking users into revealing sensitive information
    • Pretexting: creating a fake scenario to gain access to information
    • Baiting: leaving malware-infected devices or storage media in public areas

    System Vulnerabilities

    • Unpatched software: exploiting known vulnerabilities in outdated software
    • Misconfigured systems: e.g., open ports, weak passwords, unnecessary services
    • Zero-day attacks: exploiting previously unknown vulnerabilities

    Insider Threats

    • Malicious insiders: intentionally causing harm from within an organization
    • Accidental insiders: unintentionally causing harm due to lack of knowledge or carelessness

    Physical Security Breaches

    • Unauthorized access to facilities or devices
    • Theft or loss of devices or storage media containing sensitive data
    • Tampering with devices or systems

    Malware and Ransomware

    • Viruses: self-replicating code that damages systems or data
    • Trojans: malicious code disguised as legitimate software
    • Ransomware: encrypting data and demanding payment for decryption keys

    Denial of Service (DoS) and Distributed Denial of Service (DDoS) Attacks

    • Overwhelming systems with traffic to make them unavailable
    • Using multiple compromised systems to launch a coordinated attack

    SQL Injection and Cross-Site Scripting (XSS)

    • Injecting malicious code into databases to access sensitive data
    • Injecting malicious code into websites to steal user data or take control of sessions

    Reasons for Security Breach

    Human Error

    • Carelessness can lead to security flaws, such as using weak passwords or falling for phishing scams.
    • Lack of knowledge often results in misconfiguration of systems and unawareness of security best practices.
    • Negligence includes ignoring software updates and disregarding security alerts.

    Social Engineering

    • Phishing schemes deceive users into disclosing sensitive information.
    • Pretexting involves creating a fictitious scenario to manipulate individuals into providing data.
    • Baiting encourages individuals to use infected devices left in public areas, compromising systems.

    System Vulnerabilities

    • Unpatched software leaves systems open to exploitation of known vulnerabilities.
    • Misconfigured systems, such as open ports and weak passwords, can be easily attacked.
    • Zero-day attacks leverage unknown vulnerabilities, often catching organizations off guard.

    Insider Threats

    • Malicious insiders deliberately compromise security, potentially causing significant harm.
    • Accidental insiders unintentionally create security risks due to ignorance or carelessness.

    Physical Security Breaches

    • Unauthorized access can occur when individuals gain entry to restricted facilities or devices.
    • Theft or loss of devices containing sensitive information presents a serious security risk.
    • Tampering with devices or systems can lead to data breaches and operational disruptions.

    Malware and Ransomware

    • Viruses can replicate themselves and inflict damage on systems or data, leading to extensive recovery efforts.
    • Trojans masquerade as legitimate software but contain harmful payloads that can compromise systems.
    • Ransomware encrypts data and demands payment, essentially holding information hostage.

    Denial of Service (DoS) and Distributed Denial of Service (DDoS) Attacks

    • DoS attacks flood systems with excessive traffic, rendering them unavailable to legitimate users.
    • DDoS attacks involve multiple compromised systems coordinating a massive assault on targeted networks or services.

    SQL Injection and Cross-Site Scripting (XSS)

    • SQL injection involves inserting harmful code into databases, allowing unauthorized access to sensitive data.
    • XSS attacks inject malicious scripts into websites, enabling attackers to steal user data or hijack online sessions.
