CS0-003 Online Practice Questions and Answers

Correct Answer: A

A mean time to remediate (MTTR) is a metric that measures how long it takes to fix a vulnerability after it is discovered. A MTTR of 30 days would best protect the organization from the new attacks that are exploited 45 days after a patch is released, as it would ensure that the vulnerabilities are fixed before they are exploited

Correct Answer: C

Application security scanning is a process that involves testing and analyzing applications for security vulnerabilities, such as injection flaws, broken authentication, cross-site scripting, and insecure configuration. Application security scanning can help identify and fix security issues before they become exploitable by attackers. Using application security scanning as part of the pipeline for the continuous integration/continuous delivery (CI/CD) flow can help mitigate the problem of finding the same vulnerabilities in a critical application during security scanning. This is because application security scanning can be integrated into the development lifecycle and performed automatically and frequently as part of the CI/CD process.

Correct Answer: E

The analyst should look at p4wnp1_aloa.lan (192.168.86.56) first, as this is the most suspicious device on the network. P4wnP1 ALOA is a tool that can be used to create a malicious USB device that can perform various attacks, such as keystroke injection, network sniffing, man-in-the-middle, or backdoor creation. The presence of a device with this name on the network could indicate that an attacker has plugged in a malicious USB device to a system and gained access to the network.

Correct Answer: A

SLA stands for service level agreement, which is a contract or document that defines the expectations and obligations between a service provider and a customer regarding the quality, availability, performance, or scope of a service. An SLA may also specify the metrics, penalties, or remedies for measuring or ensuring compliance with the agreed service levels. An SLA can help the SOC manager review if the team is meeting the appropriate contractual obligations for the customer, such as response time, resolution time, reporting frequency, or communication channels.

Correct Answer: C

Setting up a warm disaster recovery site with the same cloud provider in a different region can help to achieve a recovery time objective (RTO) of 12 hours while keeping the costs low. A warm disaster recovery site is a partially configured site that has some of the essential hardware and software components ready to be activated in case of a disaster. A warm site can provide faster recovery than a cold site, which has no preconfigured components, but lower costs than a hot site, which has fully configured and replicated components. Using the same cloud provider can help to simplify the migration and synchronization processes, while using a different region can help to avoid regional outages or disasters . https://www.techopedia.com/definition39/memory-dump

Correct Answer: D

Using whole disk encryption is the best option to protect the d" Whole disk encryption is a technique that encrypts all data on a hard disk drive, including the operating system, applications and files. Whole disk encryption can prevent unauthorized access to the data if the laptop is lost, stolen or compromised. Whole disk encryption can also protect the data from physical attacks, such as removing the hard disk and connecting it to another device . https://www.techopedia.com/definition39/memory-dump

Correct Answer: A

Automating the use of a hashing algorithm after verified users make changes to their data is an appropriate course of action to ve" Hashing is a technique that produces a unique and fixed-length value for a given input, such as a file or a message. Hashing can help to verify the data integrity by comparing the hash values of the original and modified data. If the hash values match, then the data has not been altered without the "lues differ, then the data may have been tampered with or corrupted .

Correct Answer: BF

Review the headers from the forwarded email: Examining the email headers can provide crucial information about the email's source, path, and any intermediaries it went through. This information can help identify signs of spoofing or suspicious behavior.

Examine the SPF, DKIM, and DMARC fields from the original email: These three mechanisms (Sender Policy Framework - SPF, DomainKeys Identified Mail - DKIM, and Domain-based Message Authentication, Reporting, and Conformance DMARC) are used to authenticate the sender's domain and reduce the likelihood of email spoofing. Checking these fields can provide insights into the authenticity of the email.

Correct Answer: A

" from a trusted source is the next step the analyst should take after discovering some binaries that are exhibiting abnormal behaviors and finding unexpected content in their strings. A hash is a fixed-length value that uniquely represents the contents of a file or message. By comparing the hashes of the binaries on the compromised machine with the hashes of the original or legitimate binaries from a trusted source, such as the software vendor or repository, the analyst can determine whether the binaries have been modified or replaced by malicious code. If the hashes do not match, it indicates that the binaries have been tampered with and may contain malware.
