    Study Notes

    Untested Updates

    • Untested updates can lead to unexpected system behavior
    • Ineffective updates can cause degraded performance or instability
    • They could introduce new vulnerabilities or worsen existing ones

    Common Vulnerability

    • A common vulnerability is a flaw in software or communication protocols that can be exploited by attackers
    • This could lead to data breaches, system failures, or denial-of-service attacks

    Threat in Cybersecurity

    • A threat refers to any potential danger or harm that could affect a computer system or data
    • Threats can be intentional or unintentional, and they can come from various sources
    • Examples of threats include malware, hackers, natural disasters, and human error

    Intentional Threats

    • Intentional threats in cybersecurity are actions deliberately taken by individuals or groups to harm computer systems or data
    • Examples include:
      • Hacking
      • Malware distribution
      • Data theft
      • Sabotage

    Threat Actors

    • Threat actors are individuals or organizations that pose a threat to computer systems or data
    • They can range from individual hackers to nation-state-sponsored groups
    • They possess diverse motives, including financial gain, espionage, political activism, or personal vendetta

    Attack Vector

    • An attack vector is a method or path that attackers use to exploit vulnerabilities in a system
    • This can include various techniques like phishing emails, malicious websites, or exploiting unpatched software
    • Attack vectors can be categorized as network-based, software-based, physical, or social engineering

    Vulnerability in Cybersecurity

    • A vulnerability is a weakness or flaw in a system or software that can be exploited by attackers
    • It can be a design flaw, a coding error, or a misconfiguration
    • It allows attackers to gain unauthorized access, manipulate data, or disrupt system operations

    Example of Vulnerability

    • An example of a vulnerability is a missing security patch for a known software flaw
    • This flaw could be used by attackers to compromise the system

    Uninstalled Patches

    • Leaving systems vulnerable to known vulnerabilities that have been patched
    • Failing to install updates leaves systems vulnerable to exploits for which security patches have been released

    Threats vs. Vulnerabilities

    • Threats represent the potential danger or harm to a system, while vulnerabilities are weaknesses that allow attackers to exploit those threats
    • It's like having a door open (a vulnerability) that allows a thief to access something valuable inside (a threat)
    • You need to both minimize threats and fix vulnerabilities to secure a system
