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 References:

Least privilege, policy automation, and continuous validation are some of the key elements that need to be implemented to achieve the objective of transitioning to a zero trust architecture. Zero trust architecture is a security model that assumes no implicit trust for any entity or resource, regardless of their location or ownership. Zero trust architecture requires verifying every request and transaction before granting access or allowing data transfer. Zero trust architecture also requires minimizing the attack surface and reducing the risk of lateral movement by attackers.

A. Least privilege is a principle that states that every entity or resource should only have the minimum level of access or permissions necessary to perform its function. Least privilege can help enforce granular and dynamic policies that limit the exposure and impact of potential breaches. Least privilege can also help prevent privilege escalation and abuse by malicious insiders or compromised accounts.

C. Policy automation is a process that enables the creation, enforcement, and management of security policies using automated tools and workflows. Policy automation can help simplify and streamline the implementation of zero trust architecture by reducing human errors, inconsistencies, and delays. Policy automation can also help adapt to changing conditions and requirements by updating and applying policies in real time.

F. Continuous validation is a process that involves verifying the identity, context, and risk level of every request and transaction throughout its lifecycle. Continuous validation can help ensure that only authorized and legitimate requests and transactions are allowed to access or transfer data. Continuous validation can also help detect and respond to anomalies or threats by revoking access or terminating sessions if the risk level changes.

B. VPN is not an element that needs to be implemented to achieve the objective of transitioning to a zero trust architecture. VPN stands for Virtual Private Network, which is a technology that creates a secure tunnel between a device and a network over the internet. VPN can provide confidentiality, integrity, and authentication for network communications, but it does not providezero trust security by itself. VPN still relies on network-based perimeters and does not verify every request or transaction at a granular level.

D. PKI is not an element that needs to be implemented to achieve the objective of transitioning to a zero trust architecture. PKI stands for Public Key Infrastructure, which is a system that manages the creation, distribution, and verification of certificates. Certificates are digital documents that contain public keys and identity information of their owners. Certificates can be used to prove the identity and authenticity of the certificate holders, as well as to encrypt and sign data. PKI can provide encryption and authentication for data communications, but it does not provide zero trust security by itself. PKI still relies on trusted authorities and does not verify every request or transaction at a granular level.

E. Firewall is not an element that needs to be implemented to achieve the objective of transitioning to a zero trust architecture. Firewall is a device or software that monitors and controls incoming and outgoing network traffic based on predefined rules. Firewall can provide protection against unauthorized or malicious network access, but it does not provide zero trust security by itself. Firewall still relies on network-based perimeters and does not verify every request or transaction at a granular level.

G. Continuous integration is not an element that needs to be implemented to achieve the objective of transitioning to a zero trust architecture. Continuous integration is a software development practice that involves merging code changes from multiple developers into a shared repository frequently and automatically. Continuous integration can help improve the quality, reliability, and performance of software products, but it does not provide zero trust security by itself. Continuous integration still relies on code-based quality assurance and does not verify every request or transaction at a granular level.

H. IaaS is not an element that needs to be implemented to achieve the objective of transitioning to a zero trust architecture. IaaS stands for Infrastructure as a Service, which is a cloud computing model that provides virtualized computing resources over the internet. IaaS can provide scalability, flexibility, and cost-efficiency for IT infrastructure, but it does not provide zero trust security by itself. IaaS still relies on cloud-based security controls and does not verify every request or transaction at a granular level.

WPA3-Personal is a simple, secure solution for a small business with a single access point. It uses a new security protocol called Simultaneous Authentication of Equals (SAE), which replaces the Pre-Shared Key (PSK) exchange with a more secure way to do initial key exchange. SAE also provides forward secrecy, which means that even if the password is compromised, the attacker cannot decrypt past or future data. WPA3-Personal also uses AES-128 in CCM mode as the minimum encryption algorithm, which is resistant to offline password attacks. WPA3-Personal requires low administrative overhead and supports a single SSID with no guest access. Verified References:
