CompTIA Updated CS0-003 Exam Questions and Answers by minnie

MITRE ATT & CK is a framework and knowledge base that describes the tactics, techniques, and procedures (TTPs) used by various adversaries in cyberattacks. MITRE ATT & CK can help security analysts compare TTPs between different known adversaries of an organization, as well as identify patterns, gaps, or trends in adversary behavior. MITRE ATT & CK can also help security analysts improve threat detection, analysis, and response capabilities, as well as share threat intelligence with other organizations or communities

The correct answer is B. CASB. A Cloud Access Security Broker is specifically designed to sit between users and cloud services, monitor cloud activity, enforce access policies, and provide visibility into unauthorized cloud storage use. This directly matches the question’s requirement: showing user access to prohibited cloud storage and whether a file was downloaded to a personal device.

Exact supporting extract: the All-in-One CySA+ guide explains that a CASB “sits between each user and each cloud service,” monitors activity, enforces policies, and alerts when something is wrong. It also lists visibility as a CASB pillar, including whether users are connecting to unauthorized resources such as cloud storage not controlled by the organization.

The Sybex CySA+ Study Guide also states that CASB tools enforce security policies when cloud resources and services are used, and can help with data security, service usage and access visibility, and risk management.

The official CompTIA CySA+ CS0-003 objectives include Cloud Access Security Broker (CASB) under identity and access management / security operations architecture concepts.

Why the other options are incorrect:

A. SASE is broader architecture that may include CASB, SWG, FWaaS, and SD-WAN, but the specific tool for cloud-service visibility and policy logging is CASB.

C. EDR focuses on endpoint detection and response, not cloud storage access monitoring across cloud services.

D. SDN is software-defined networking and does not provide user-level cloud storage access logs.

The NTP configuration on each system should be checked first, as it is essential for ensuring accurate and consistent time stamps across different systems. NTP is the Network Time Protocol, which is used to synchronize the clocks of computers over a network. NTP uses a hierarchical system of time sources, where each level is assigned a stratum number. The most accurate time sources, such as atomic clocks or GPS receivers, are at stratum 0, and the devices that synchronize with them are at stratum 1, and so on. NTP clients can query multiple NTP servers and use algorithms to select the best time source and adjust their clocks accordingly1. If the NTP configuration is not consistent or correct on each system, the time stamps of the logs and events may differ, making it difficult to correlate incidents across different systems. This can affect the security analysis and correlation of events, as well as the compliance and auditing of the network23.

After recovering a compromised server to its previous state, the analyst should perform forensic analysis to determine the root cause, impact, and scope of the incident, as well as to identify any indicators of compromise, evidence, or artifacts that can be used for further investigation or prosecution.
