CompTIA SecurityX Practice Test (CAS-005)

Older sensors that cannot be updated benefit from network isolation. A separate VLAN with restricted traffic paths hinders lateral movement and contains threats. Advanced user controls or audit logs do not fully address underlying vulnerabilities or limit interactions, and decommissioning is not valid when hardware must remain operational.

An automated scanning approach that assigns protective measures by analyzing and flagging critical details provides consistent coverage. Manual processes can miss items during peak times, inherited settings may become outdated as data evolves, and consolidating related content in a single location does not maintain reliable policies for distributed repositories.

Using a specialized external service to detect suspicious traffic ensures harmful flows are rejected before reaching internal infrastructure. This reduces overload on local systems. Filtering requests on each host relies on static entries that become ineffective when attackers rotate addresses. Simply adding capacity may delay problems but does not stop harmful data. Raising connection thresholds can also block legitimate users when a surge overwhelms the system.

Enabling parallel processing on the secure device allows multiple signing operations at once, preserving tamper protections and preventing key exposure. Offloading cryptographic tasks to a general-purpose system removes dedicated safeguards, storing keys unencrypted breaks core security principles, and extending time windows does not address the actual performance bottleneck.

Code stylometry examines programming patterns that persist across different binaries, allowing analysts to attribute samples to specific threat actor toolsets. Unlike behavior analysis or log comparison, which confirm malicious activity or operational context, stylometry links binaries based on development style, aiding in attribution. This makes it an effective method for associating unknown binaries with previously observed malicious code bases.

Using a script that activates right after the operating system sends its notification addresses specific entries as they happen and reduces manual effort. By listening for each event, the environment can react with minimal delay. A daily job imposes a waiting period and can create gaps where issues remain undetected for hours. Launching a script by clicking a prompt requires constant operator vigilance. A remote push that relies on a verification step might intervene too late, undermining the advantage of automatic detection.

Combining more than one environment supports heavier usage demands while adding a protective measure to deter harmful activity. Relying on a single environment or reducing detection capabilities may provide speed, but it weakens defenses. Emphasizing data encryption alone ensures confidentiality, yet it does not address managing high traffic or halting dangerous behavior. Increasing capacity without proper safeguards covers volume but disregards data protection needs.

A threshold-based algorithm divides the secret among multiple parties, requiring a set number of them to combine their shares for access. Storing the secret in one hardware device centralizes it and does not require multiple shares. A passphrase policy might manage credentials across personnel but does not rely on sharing portions of the secret. Local encryption with unique passcodes isolates individual data instead of creating a unified threshold scheme.

When a switch is not configured to pass extended authentication messages over its interfaces, devices can join the network without being prompted for credentials. Adjusting the trunk interface so it supports 802.1X or other port-based authentication ensures request and response traffic is not dropped. Enabling DNS filtering, reissuing certificates, or monitoring suspicious activity at the edge do not fix the underlying data-link problem that permits access without authentication.

Accessing memory through a hardware debug interface provides full visibility into embedded system data, including volatile memory and hidden regions inaccessible to OS-level tools. This method avoids dependency on potentially compromised firmware and ensures a comprehensive snapshot. Relying on system utilities or logs risks incomplete data capture and omits critical forensic artifacts.

The Digital Markets Act (DMA) is designed to regulate large tech companies—referred to as gatekeepers—to prevent unfair practices that disadvantage smaller competitors. It aims to promote a more balanced and competitive digital market in the EU. While GDPR covers data privacy, the Payment Services Directive governs financial services, and the Cyber Resilience Act focuses on security standards, none of these directly address platform dominance or market fairness.

Access control lists (ACLs) are processed top-down, and once a match is found, subsequent rules are ignored. If a general deny rule precedes a specific permit, intended access will be blocked. Placing permit rules for specific subnets before the deny-all rule ensures proper functionality and expected access without removing security controls.

Generating a new session key for each connection limits the impact of intercepted traffic. This technique, often used in protocols supporting Perfect Forward Secrecy, ensures that even if one session key is compromised, past and future sessions remain secure. Reusing a static certificate or long-term key creates risk, and hashing alone doesn’t encrypt data — it only verifies integrity. Temporary session keys are ideal for protecting sensitive traffic between remote offices.

Virtual systems placed in separate sites help maintain operations when key infrastructure fails. Tested failover procedures verify that the backup environment can handle the load. Storing archives locally does not provide resilience beyond the damaged facility. Applying patches helps with stability but does not ensure services continue in the event of a larger outage. Network monitoring does not protect against system failures that disrupt service entirely.

To preserve repository history while preventing further exposure, it’s best to remove the sensitive credential from all new commits and immediately rotate the compromised secret. This ensures that future use of the exposed value is invalidated, and no additional commits contain the sensitive data. Other actions, such as deleting commit history or redacting a single commit, do not address all instances of exposure and may introduce operational or audit challenges.

A single management solution streamlines key use across on-premises and external resources. Other methods rely on multiple software setups, manual handling, or insecure distribution channels, which can result in inconsistent practices and administrative complications.

Reviewing data flow and architecture before integrating new services helps identify how trust boundaries are affected and where new vulnerabilities may emerge. This process allows teams to spot previously unmonitored entry points, ensuring layered security and limiting attack surface expansion. Scanning code or enforcing firewall rules alone cannot capture these architectural risks. Blocking external traffic entirely undermines business objectives without resolving underlying security concerns.

This approach dictates how teams mobilize and communicate during impactful events, ensuring that executive direction, resource utilization, and stakeholder notification are unified. Asset inventory processes, configuration management, and vendor risk oversight do not focus on orchestrating an organization-wide response to pressing disruptions.

This method generates a result that shifts whenever the original material shifts, drawing attention to unauthorized changes. Encoding data only conceals information, compression reduces size, and access controls restrict usage. None of those indicate if a file has been tampered with.

Increasing the level of network logs and applying segmentation constraints prevents unauthorized flows and better highlights any malicious patterns. Extended logging captures unusual traffic, while segmentation restricts channels for data extraction. Blocking all foreign connections hinders necessary business interactions. Disabling secure channels compromises data integrity. Verifying partner addresses alone is not enough without further security controls.
