Some end users of an e-commerce website are reporting a delay when browsing pages. The website uses TLS 1.2. A security architect for the website troubleshoots by connecting from home to the
website and capturing tramc via Wire-shark. The security architect finds that the issue is the time required to validate the certificate. Which of the following solutions should the security architect
recommend?
OCSP stapling is a solution that allows the web server to provide a time-stamped OCSP response signed by the CA along with the certificate during the TLS handshake, eliminating the need for the client to contact the CA separately to validate the certificate. OCSP stapling can reduce thedelay caused by the certificate validation process by saving a round-trip between the client and the CA. It can also improve the security and privacy of the certificate validation by preventing potential attacks or tracking by malicious third parties. Verified Reference:

In a shared responsibility model for PaaS, which of the following is a customer's responsibility?
In a shared responsibility model for PaaS, the customer's responsibility is OS security. PaaS stands for Platform as a Service, which is a cloud service model that provides a platform for customers to develop, run, and manage applications without having to deal with the underlying infrastructure. The cloud provider is responsible for the physical security, network security, and host infrastructure of the platform, while the customer is responsible for the security of the operating system, the application, and the data. The customer needs to ensure that the operating system is patched, configured, and protected from malware and unauthorized access. Verified Reference:

A company moved its on-premises services to the cloud. Although a recent audit verified that data throughout the cloud service is properly classified and documented, other systems are unable to act or filter based on this information. Which of the following should the company deploy to allow other cloud-based systems to consume this information?
Step by Step
Data labeling enables metadata tagging for data classification, which allows systems to filter, act, and enforce policies based on the labels.
Data mapping is used for understanding data flows but does not support automation.
Log scraping and resource tagging are unrelated to enabling system actions based on data classification.
