NEW QUESTION # 14
Which of the following helps identify the attack surface area of a new environment?
Answer: A
Explanation:
The Cyber Kill Chain provides a structured model of the stages of a cyberattack, from reconnaissance through exploitation and data exfiltration. By mapping potential attack paths across these stages, analysts can identify where an attacker could interact with systems and services in the environment. This helps reveal exposed entry points and weaknesses, effectively identifying the environment's attack surface area.
NEW QUESTION # 15
Customers are unable to upload files to an SFTP server. Firewall logs show the following activity sourced from multiple IP addresses in one geographic region:
The analyst reviewing the logs notices that the session_end_reason does not change for any of the log entries. Which of the following is the next step the analyst should take to determine what is occurring?
Answer: B
Explanation:
The firewall log shows TCP traffic to port 22 is being allowed, but the sessions consistently end with an "aged-out/incomplete" status. This commonly indicates that the TCP three-way handshake is not completing. Capturing packets to determine whether the server is responding properly and whether clients are completing the handshake is the appropriate next step to identify where the connection process is failing.
NEW QUESTION # 16
A binary file that might contain malicious code is hosted on an isolated machine. An analyst wants to quickly detect the malicious code.
Which of the following should the analyst use?
Answer: A
Explanation:
YARA is specifically designed to identify and classify suspicious or malicious files through pattern-based rules . A YARA rule can contain textual strings, hexadecimal byte sequences, regular expressions, metadata, file characteristics, and Boolean conditions. This makes YARA particularly effective when an analyst already has a binary specimen on an isolated analysis system and needs to determine whether it contains patterns associated with malware.
The official YARA documentation describes YARA as a tool for helping malware researchers identify and classify malware samples using textual and binary patterns. Rules consist primarily of strings and logical conditions that determine whether a file matches the defined characteristics.
The strings utility can reveal printable characters embedded within a binary and is useful during preliminary static analysis, but it does not itself classify the file against structured malware-detection signatures.
VirusTotal can perform multi-engine analysis, but submitting a potentially sensitive binary from an isolated environment to an external service may be inappropriate and is unnecessary when local YARA detection is available. WHOIS provides registration information about internet resources and has no direct binary- malware detection capability.

NEW QUESTION # 17
A server was recently compromised. A security analyst needs to collect artifacts for further analysis before disconnecting the server from the network.
Which of the following artifacts should the analyst collect first?
Answer: B
Explanation:
The analyst should collect the Netstat output first because current network-connection information is highly volatile and will change immediately when the server is disconnected. netstat-type evidence can identify active TCP/UDP connections, listening services, remote endpoints, and potentially the communication channels associated with an attacker or command-and-control infrastructure.
Digital-forensic acquisition follows the order of volatility : evidence most likely to disappear or change should be captured before more persistent artifacts. RFC 3227 explicitly directs investigators to proceed from volatile to less-volatile evidence and identifies information such as routing data, ARP cache, process state, memory-related information, and network state as highly time-sensitive.
The ARP table is also volatile and should be captured early, but the wording "before disconnecting the server from the network" makes active connection state particularly important because those sessions will terminate when network connectivity is removed. ShellBags are persistent forensic artifacts stored within Windows Registry data and can be collected later from disk. A hard-disk image is critical but comparatively nonvolatile and should follow acquisition of live state.
Therefore, live network-session information takes priority.
Study Guide Reference: Incident Response and Management # Evidence Acquisition # Order of Volatility # Live Response # netstat # Network Connections # Forensic Preservation.
NEW QUESTION # 18
A security analyst IS comparing the results of the past and current active credentialed vulnerability scans:
Past scan:
Current scan:
Which of the following should the analyst do next?
Answer: B
Explanation:
The current scan shows that a previously low-severity SSL vulnerability has increased to a high- severity (9.1) issue with potential information disclosure. This means the organization now faces a significantly greater risk than before. Management must be informed because the company's assets could be leveraged in attacks or suffer data exposure, and leadership needs awareness to prioritize remediation.
