You may have been learning and trying to get the CS0-004 certification hard, and good result is naturally become our evaluation to one of the important indices for one level. When looking for a job, of course, a lot of companies what the personnel managers will ask applicants that have you get the CS0-004certification to prove their abilities, therefore, we need to use other ways to testify our knowledge we get when we study at college , such as get the CS0-004 Test Prep to obtained the qualification certificate to show their own all aspects of the comprehensive abilities, and the CS0-004 exam guide can help you in a very short period of time to prove yourself perfectly and efficiently.
NEW QUESTION # 46
The website of a large retail chain is falling to enforce encrypted HTTPS connections, leaving customer account credentials exposed. Which of the following is the best corrective action for resolving this issue?
Answer: A
Explanation:
Enabling HTTP Strict Transport Security forces browsers to use HTTPS exclusively, preventing any unencrypted HTTP connections. This ensures customer credentials cannot be transmitted in plaintext and corrects the failure to enforce secure connections.
NEW QUESTION # 47
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: C
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 # 48
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.

NEW QUESTION # 49
A security operations center analyst is using the command line to display specific traffic. The analyst uses the following command:
$tshark -r file.pcap -Y "http or udp"
Which of the following will the command line display?
Answer: C
Explanation:
The http display filter selects plaintext HTTP traffic, while udp includes UDP-based traffic such as standard DNS queries. HTTPS traffic is not matched as HTTP because it is encrypted.
NEW QUESTION # 50
An incident response team investigates a possible data leak. Various IT systems collect evidence.
Which of the following processes is required to ensure that evidentiary artifacts are properly recorded?
Answer: B
Explanation:
Chain of custody is the formal process used to document the collection, possession, transfer, handling, analysis, and disposition of evidentiary artifacts. Its purpose is to establish an auditable history demonstrating who controlled the evidence, when custody changed, why it was transferred, and what actions were performed on it.
NIST defines chain of custody as tracking evidence throughout its collection, safeguarding, and analysis lifecycle while documenting each individual who handled it, relevant timestamps, and the purpose of transfers. This is critical when multiple systems, analysts, forensic teams, or external parties participate in an investigation because undocumented handling could undermine confidence in the evidence's integrity or admissibility.
Packaging and labeling are important evidence-preservation procedures, but they represent only individual activities within the broader evidence-management process. Storage and containment protect artifacts from alteration or unauthorized access but do not provide the complete historical record of possession. Post- incident reporting documents investigation conclusions and response actions after the incident rather than tracking evidence throughout its lifecycle.
The decisive phrase is "properly recorded." A defensible record of every evidence transfer and handler is specifically the function of chain of custody.
