質問 # 32 
Refer to the exhibit. Which determination should be made by a security analyst?
正解：A
質問 # 33
Refer to the exhibit.
A company that uses only the Unix platform implemented an intrusion detection system. After the initial configuration, the number of alerts is overwhelming, and an engineer needs to analyze and classify the alerts.
The highest number of alerts were generated from the signature shown in the exhibit. Which classification should the engineer assign to this event?
正解：B
解説：
The alert shown is based on a Snort rule for a Unicode directory traversal attack against IIS web servers (Microsoft platform). The key detail here is the payload content " ../..%c0%af../ " which is a classic IIS- specific exploit related to CVE-2000-0884.
Since the company only uses Unix systems, they are not vulnerable to this IIS-specific attack. Therefore, these alerts are triggered by irrelevant traffic or misapplied signatures, resulting in False Positives.
As defined in the Cisco CyberOps guide:
"False Positive: an alert is generated for traffic that is not actually malicious or relevant to the protected environment".
質問 # 34
Refer to the exhibit.
正解：D
解説：
The string shown is long, alphanumeric, and includes both uppercase and lowercase letters with numbers- characteristics of Base64 encoding. This format is widely used to obfuscate payloads in malicious scripts, particularly in phishing or malware campaigns. Base64 encoding is also supported by Python and other platforms for data transformation.

質問 # 35
A small company must create a temporary detection solution for distributed denial-of-service attacks. An engineer installs Suricata IDPS on an Ubuntu virtual machine and adds a denial-of-service detection rule.
Which rule headers must be used to alert on a SYN-flood attack?
正解：C
解説：
A SYN flood abuses the TCP handshake, so the applicable Suricata signature must inspect TCP traffic rather than DNS- or HTTP-only application traffic. Option B correctly scopes traffic between the untrusted
$EXTERNAL_NET and protected $HOME_NET, including the inbound direction in which attack SYN packets would normally arrive and the return direction used for correlation. Option C is unnecessarily broad because any ignores the defined trust boundaries. Strictly speaking, the displayed lines are only rule headers; a production SYN-flood signature must also include options that identify SYN-only behavior and a rate condition, such as TCP flags and a threshold or detection filter. Without those options, it would alert on ordinary TCP traffic. Suricata's official rule documentation confirms that a header defines action, protocol, addresses, ports, and direction. This belongs to CBRFIR incident-alert interpretation and mitigation. Suricata rule format
