Zorluk: ZorKey Security Concepts, Threats, Vulnerabilities, and Mitigations

Match each enterprise security threat scenario on the left with its most effective primary mitigation strategy on the right.

  • Password Spray Attack attempting low-frequency authentication across hundreds of corporate accountsEnforcing Multi-Factor Authentication (MFA) and smart lockout policies based on risk telemetry
  • Man-in-the-Middle (MitM) eavesdropping on unencrypted transit traffic across an untrusted network segmentImplementing end-to-end cryptographic transport protocols (TLS/IPsec) with strict certificate validation
  • Spear Phishing campaign directing executive targets to a spoofed login portalDeploying email authentication standards (SPF/DKIM/DMARC) paired with user awareness training
  • Zero-Day software vulnerability targeting an unpatched network management daemonApplying vendor micro-segmentation, intrusion prevention signatures, and rapid security patching

Cevap

Password Spray Attack matches Multi-Factor Authentication (MFA) and smart lockout policies. Man-in-the-Middle eavesdropping matches end-to-end cryptographic transport protocols (TLS/IPsec). Spear Phishing matches email authentication standards (SPF/DKIM/DMARC) and user training. Zero-Day software vulnerability matches vendor micro-segmentation, IPS signatures, and rapid patching.
Each threat targets a specific layer or operational vulnerability, requiring an aligned mitigation control: Password Spraying is countered by Multi-Factor Authentication; Man-in-the-Middle transit interception is countered by TLS/IPsec encryption; Spear Phishing is countered by SPF/DKIM/DMARC and security awareness; and Zero-Day software flaws are countered by IPS signatures, network segmentation, and prompt patching.

Adım Adım Çözüm

1
Analyze the Password Spray threat vector.
Identify that password spraying avoids single-account lockout by trying one password against many accounts.
MFA is the primary defense because even if a password matches, login fails without the second factor.
2
Analyze the Man-in-the-Middle (MitM) threat vector.
Identify that MitM exploits cleartext communication channels.
Cryptographic transport protocols like TLS and IPsec encrypt payload data and verify server identity via certificates.
3
Analyze the Spear Phishing threat vector.
Identify that spear phishing uses targeted fraudulent emails to fool specific personnel.
Combining domain verification controls (SPF/DKIM/DMARC) with human security training reduces email spoofing and link clicking.
4
Analyze the Zero-Day vulnerability threat vector.
Identify that zero-day exploits target unpatched software weaknesses.
Deploying IPS signatures, micro-segmentation, and timely vendor security patches directly mitigates software vulnerability risks.
