Question 206:
Answer: STRIDE

  • STRIDE is a threat-modeling framework that organizes threats into six categories: Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege.
  • The CISO’s concerns map directly to STRIDE:
- Denial of Service ? high availability (99.999% uptime) - Information Disclosure ? ensuring users only view data they’re authorized to see
  • Why not the others:
- CAPEC catalogs attack patterns, not a threat-modeling framework for system-level threats. - ATT&CK is a knowledge base of attacker techniques, not a formal threat-modeling framework. - TAXII is a threat intel exchange protocol, not used for threat modeling.
So STRIDE directly addresses the CISO’s availability and data-access concerns.

Question 192:

  • Answer: B — The samples were probably written by the same developer.

  • Why this is correct:
- The code shows consistent naming conventions and coding style across both samples (e.g., knockEmDown, sendC2, toString(), address.keepAlive("paranoid"), target.toShell(e)). - Such stylistic similarities strongly suggest a common author or shared template, which is a common basis for attributing malware to the same developer.
  • Why the other options are less likely:
- A: Telemetry buffering mode isn’t shown or established as the key indicator for authorship. - C: Use of IP connectivity for C2 could be common across malware families; it doesn’t imply authorship. - D: inferring which sample is the target agent vs. C2 server isn’t supported by the observable similarities.

Question 8:

  • Answer: No. The solution does not meet the goal.

  • Why:
- For an Azure Internal Load Balancer (ILB) used as a listener for a SQL Server Always On availability group, the health probe must be a TCP probe on the port used by the AG listener (default is port 1433, or the port you configured). - An HTTP health probe cannot reliably validate SQL Server endpoints, so it won’t correctly reflect the health of the AG listener.
  • What to configure instead:
- Create an ILB with a backend pool that includes the VMs hosting the AG replicas. - Create a TCP health probe on port 1433 (or the actual listener port). - Create a load-balancing rule for the AG listener port to route to the backend pool.
  • Key concept: ILB health probes must align with the service being load-balanced. SQL Server endpoints require TCP checks, not HTTP checks.

Question 108:

  • Correct answer: A

  • Why: A flat internal cloud network means all hosts can reach each other and any public-facing storage may be exposed. Implementing segmentation with ACLs restricts which networks/hosts can access sensitive file storage, reducing exposure and limiting blast radius.

  • Why not the others:
- B (logging/monitoring to SIEM) helps detect issues but doesn’t prevent exposure caused by a flat network. - C (MFA for cloud storage) improves authentication but doesn't address insecure network access to storage. - D (IDS) detects threats after they occur and doesn’t restrict access to the sensitive locations.

Question 82:
I can’t view the [Image] in Log entries. If you paste the text of Log entry 1–4 or describe the payloads, I can identify which shows the exploitation.
In general, for a zero-day command injection, look for:

  • Log entries showing input that appears to be passed to a shell or OS command (e.g., attempts to execute ls, whoami, uname -a, or wget/curl from a web input).
  • Use of command metacharacters in user input (e.g., ;, &, |, $(), ${...}, backticks).
  • HTTP requests with suspicious query strings or POST bodies that include shell-like commands or encoded payloads.
  • Unexpected process creation or web server issuing OS commands (e.g., new /bin/sh or cmd.exe spawned).

How to decide which is evidence:
  • Compare entries for evidence of command execution originating from user input.
  • Check for anomalies that shouldn’t be possible from normal traffic (rare file writes, new executables, or outbound connections triggered by web input).
  • Correlate with timing and any known vulnerability active window.

If you share the actual logs, I’ll pinpoint which one indicates exploitation and explain why.

Question 12:
Correct answer: D. Exploitation

  • In the Cyber Kill Chain, the stages are:
- Reconnaissance: gather information - Weaponization: prepare the exploit - Delivery: transmit the payload - Exploitation: exploit the vulnerability to gain access
  • In this scenario, the attacker gained access to the internal network via social engineering. Since they have already turned the vector into access, they are at the Exploitation stage.

  • Why not the others:
- Reconnaissance: before attack, not after access is gained - Weaponization: preparation work done before delivery - Delivery: sending the payload, which would precede how access is gained
Note: "Doesn’t want to lose access" points toward persistence actions, but among the given options, Exploitation best fits the current stage.

Question 3:

  • Answer: C: Configure an Access-Control-Allow-Origin header to authorized domains.

Why: The output likely indicates a CORS misconfiguration. CORS controls which origins can make cross-origin requests to your web app. By setting Access-Control-Allow-Origin to specific, trusted domains, you prevent unauthorized sites from reading or interacting with your resources.
Why the other options are less appropriate:
  • Set an HttpOnly flag to force communication by HTTPS: HttpOnly affects cookie ??????? via client-side scripts, not transport security. HTTPS enforcement is done with TLS, not HttpOnly.
  • Block requests without an X-Frame-Options header: X-Frame-Options mitigates clickjacking, not cross-origin data access.
  • Disable the cross-origin resource sharing header: This would remove restrictions and increase exposure; you should restrict origins, not disable CORS.

UTM STANDS FOR
Unified Threat Management.
It’s an integrated security appliance that combines multiple controls (e.g., firewall, IDS/IPS, antivirus/malware scanning, VPN, content filtering) to protect the network perimeter.

Question 332:

  • The correct answer is: B. Reimage the end user's machine.

  • Why: The SOC has a live indication of a potential compromise (remote control, credential-like data). In incident response, containment/eradication takes precedence to stop malware persistence and possible exfiltration. Reimaging quickly cleans the host so you’re not just “mitigating” by changing credentials.

  • About the assumption: It isn’t that the compromise is fully confirmed or all evidence is already collected. The scenario describes suspicious activity that warrants immediate containment to reduce risk. Evidence collection can occur after containment.

  • Why not the others:
- A: Advising password changes is remediation for credential theft, but not the immediate containment needed if the host is compromised. - C: Checking the personal email policy addresses policy, not incident containment. - D: Checking host firewall logs is diagnostic and not the first action when a suspected remote-control compromise is identified.
  • Practical nuance: If feasible, you might quickly gather volatile data (RAM, running processes) before reimage, but the exam’s best-practice choice prioritizes containment/eradication first.
