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

While serverless computing abstracts the infrastructure layer from developers, organizations must still ensure the security of their data in the serverless environment. This includes protecting the data from unauthorized access and ensuring data privacy and integrity. Serverless architectures can be complex, and understanding the security model and shared responsibility is essential for safeguarding applications and services.

Traffic mirroring, also known as port mirroring or SPAN (Switched Port Analyzer), involves creating a copy of the actual network traffic for independent analysis. This would allow the third-party vendor to review communications between infrastructure endpoints, identify unauthorized and malicious data patterns, and perform automated, risk-mitigating configuration changes without impacting the live environment. This is used in network intrusion detection systems (NIDS) and for traffic analysis purposes.

Passwordless authentication is an authentication method that does not require the user to enter a password. Instead, it relies on alternative forms of verification, such as biometric readers (fingerprint or facial recognition), proximity badge entry systems, and hardware security tokens. These technologies provide a means to authenticate users with higher assurance levels and would benefit the most from the use of the mentioned devices and methods.

The root cause of this issue is that the iOS keychain imported only the client public and private keys, but not the CA certificate. A PKCS#12 file (.p12 or .pfx) is a file format that contains a certificate and its private key, optionally protected by a password. A PKCS#12 file can also contain intermediate certificates or root certificates that are needed to verify the certificate chain. However, when importing a PKCS#12 file into the iOS keychain, only the certificate and its private key are imported, not the CA certificate. This means that the iOS device cannot verify the authenticity of the certificate, and displays the error message “mbedTLS: ca certificate undefined”. To fix this issue, the CA certificate needs to be imported separately into the iOS keychain, either manually or using a configuration profile. Verified References:

The Security Content Automation Protocol (SCAP) is a method for using specific standards to enable automated vulnerability management, measurement, and policy compliance evaluation. Using SCAP can help to identify vulnerabilities, including those without standard definitions, and ensure they are tracked and managed effectively.

The most significant risk to the development of a machine-learning-based threat detection tool is the Big Data processing required for maturity. Machine learning models often require large datasets to train effectively, and processing and analyzing this data can be time-consuming and resource-intensive. This can delay the development timeline, especially in a rapid CI/CD pipeline environment where timely delivery is crucial. CASP+ highlights the challenges associated with machine learning and Big Data in security tool development, particularly the resource demands and the need for extensive data to ensure accuracy and maturity.

An inspection proxy, also known as an SSL/TLS inspection proxy, can decrypt HTTPS traffic, allowing the IDS to analyze the content for malicious activity. This method ensures that encrypted traffic can be inspected without compromising the security of the data in transit. The inspection proxy will re-encrypt the data before sending it on to its destination, maintaining the confidentiality of the communication while enabling security tools to perform their functions.

Hardening the engineering workstations using a consistent strategy would have the greatest impact on reducing the attack surface. The workstations are running outdated and unsupported operating systems, with no security controls, and inconsistent software installations, which significantly increases the risk of exploitation. Hardening involves applying patches, reducing unnecessary software, disabling unused services, and ensuring uniform security controls across all systems. By addressing these vulnerabilities and inconsistencies, the overall security posture improves significantly, which aligns with CASP+ best practices on reducing attack surfaces by standardizing and securing endpoint configurations.
