CAS-004 Exam Dumps - CompTIA Advanced Security Practitioner (CASP+) Exam

Comprehensive and Detailed Step by Step Explanation:

Data masking obscures sensitive data displayed on screens, such as masking certain characters (e.g., showing *** for parts of SSNs).

It allows legitimate use while protecting the data from being misused or stolen.

Encryption is unrelated because it protects data in transit or at rest but does not address how it is displayed.

Tokenization replaces data with a token but is more relevant for storage and transactional systems, not screen data.

Scrubbing refers to cleansing datasets but does not address this scenario.

SOAR solutions (Security Orchestration, Automation, and Response) are designed to help organizations efficiently manage security operations. They can automate the collection and analysis of security data, which improves the performance of a security operations center (SOC) by allowing the security team to focus on more strategic tasks and reduce response times to incidents.

Agent-based scanning is best suited for environments with multiple subnets, VLANs, and branch offices, as described. It allows for fast scanning with fewer false positives, and since the agents are installed on the servers, they tend to have a lower impact on performance. This type of scanning also facilitates signature-based scanning, which is one of the customer's requirements.

The SAN (Subject Alternative Name) field in a certificate can include multiple types of entries, including DNS names and email addresses. These are explicit options within the SAN extension, allowing a single certificate to be valid for multiple domain names and email addresses. This is often used in multi-domain SSL certificates, where a single certificate needs to be valid for multiple subdomains or different domain names.

An ISA, or interconnection security agreement, is a document that should be required to set up a dedicated VPN between two entities that provide specialized help desk services. An ISA defines the technical and security requirements for establishing, operating, and maintaining a secure connection between two or more organizations. An ISA also specifies the roles and responsibilities of each party, the security controls and policies to be implemented, the data types and classifications to be exchanged, and the incident response procedures to be followed.

Resource exhaustion is a condition that occurs when a system or service runs out of resources, such as memory, CPU, disk space, or bandwidth, and becomes unable to function properly or respond to requests. Resource exhaustion can be caused by high demand, poor design, misconfiguration, or malicious attacks, such as denial-of-service (DoS).

Resource exhaustion would be the most significant business risk to a company that signs a contract with a cloud service provider (CSP) that is able to provide the same uptime as other CSPs at a markedly reduced cost, because this could:

Indicate that the CSP is oversubscribing or underprovisioning its resources, which could result in performance degradation, service disruption, or data loss for the company.

Affect the company’s availability, reliability, and scalability requirements, which could impact its operations, reputation, and customer satisfaction.

Expose the company to potential security breaches or compliance violations, if the CSP does not implement adequate security controls or measures to prevent or mitigate resource exhaustion.

The consultant should use the customer-provided VDI solution to perform work on the customer’s environment. VDI stands for virtual desktop infrastructure, which is a technology that allows users to access a virtual desktop hosted on a remote server. VDI can help meet the customer’s requirements by ensuring that all customer data remains under the customer’s control at all times, that third-party access to the customer environment is controlled by the customer, and that authentication credentials and access control are under the customer’s control.

Remote access services deployed using vendor-diverse redundancy with event response driven by playbooks is the best solution to meet the requirements. Vendor-diverse redundancy means using different vendors or technologies to provide the same service or function, which can increase the availability and resilience of the service. For example, if one vendor’s VPN solution fails due to a zero-day vulnerability, another vendor’s VPN solution can take over without affecting the users. Event response driven by playbooks means using predefined workflows or scripts to automate the actions or decisions that need to be taken in response to certain events or triggers. For example, a playbook can define how to switch between different remote access solutions based on certain criteria or conditions, such as performance, availability, security, or manual input. Playbooks can also be integrated with SOAR platforms to leverage their capabilities for orchestration, automation, and response. Verified References:
