質問 # 83
Which of the following risk management decisions should be considered after evaluating all other options?
正解：B
解説：
Risk Acceptance means acknowledging a risk and choosing not to take further action because the cost of mitigation may outweigh the benefits.
It is the last resort when:
The risk is low impact or unlikely to occur.
Other options (mitigation, transfer, avoidance) are not feasible.
Why Not Other Options?
A (Transfer) → Moving risk to a third party (e.g., insurance).
C (Mitigation) → Implementing security controls to reduce risk.
D (Avoidance) → Eliminating the risk entirely (e.g., discontinuing a service).

A security audit for unsecured network services was conducted, and the following output was generated:
Which of the following services should the security team investigate further? (Select two).
正解：B、E
解説：
The output shows the results of a port scan, which is a technique used to identify open ports and services running on a network host. Port scanning can be used by attackers to discover potential vulnerabilities and exploit them, or by defenders to assess the security posture and configuration of their network devices1 The output lists six ports that are open on the target host, along with the service name and version associated with each port. The service name indicates the type of application or protocol that is using the port, while the version indicates the specific release or update of the service. The service name and version can provide useful information for both attackers and defenders, as they can reveal the capabilities, features, and weaknesses of the service.
Among the six ports listed, two are particularly risky and should be investigated further by the security team:
port 23 and port 636.
Port 23 is used by Telnet, which is an old and insecure protocol for remote login and command execution.
Telnet does not encrypt any data transmitted over the network, including usernames and passwords, which makes it vulnerable to eavesdropping, interception, and modification by attackers. Telnet also has many known vulnerabilities that can allow attackers to gain unauthorized access, execute arbitrary commands, or cause denial-of-service attacks on the target host23 Port 636 is used by LDAP over SSL/TLS (LDAPS), which is a protocol for accessing and modifying directory services over a secure connection. LDAPS encrypts the data exchanged between the client and the server using SSL/TLS certificates, which provide authentication, confidentiality, and integrity. However, LDAPS can also be vulnerable to attacks if the certificates are not properly configured, verified, or updated. For example, attackers can use self-signed or expired certificates to perform man-in-the-middle attacks, spoofing attacks, or certificate revocation attacks on LDAPS connections.
Therefore, the security team should investigate further why port 23 and port 636 are open on the target host, and what services are running on them. The security team should also consider disabling or replacing these services with more secure alternatives, such as SSH for port 23 and StartTLS for port 6362

While reviewing web server logs, a security analyst discovers the following suspicious line:
Which of the following is being attempted?
正解：B
解説：
The suspicious line in the web server logs is an attempt to execute a command on the server, indicating a command injection attack. Reference: CompTIA CySA+ Study Guide: Exam CS0-003, 3rd Edition, Chapter 5, page 197; CompTIA CySA+ CS0-003 Certification Study Guide, Chapter 5, page 205.
質問 # 86
A security analyst notices the following proxy log entries:
Which of the following is the user attempting to do based on the log entries?
正解：C
解説：
Scanning the network is what the user is attempting to do based on the log entries. The log entries show that the user is sending ping requests to various IP addresses on different ports using a proxy server. Ping requests are a common network diagnostic tool that can be used to test network connectivity and latency by sending packets of data and measuring their response time. However, ping requests can also be used by attackers to scan the network and discover active hosts, open ports, or potential vulnerabilities .
質問 # 87
An analyst discovers unusual outbound connections to an IP that was previously blocked at the web proxy and firewall. Upon further investigation, it appears that the proxy and firewall rules that were in place were removed by a service account that is not recognized. Which of the following parts of the Cyber Kill Chain does this describe?
正解：C
解説：
The Command and Control stage of the Cyber Kill Chain describes the communication between the attacker and the compromised system. The attacker may use this channel to send commands, receive data, or update malware. If the analyst discovers unusual outbound connections to an IP that was previously blocked, it may indicate that the attacker has established a command and control channel and bypassed the security controls.
