SecurityX CAS-005 endpoint security and network control objectives emphasize least privilege network access.
Creating a firewall rule to allow outbound traffic only via a proxy (A) ensures centralized inspection and control.
Configuring the proxy to allow only the required FQDNs for EDR management communication (C) limits exposure to necessary destinations.Options D and E allow broader access than necessary, and B would block required communications entirely. F relies on blocklists instead of allowlists, which is less secure for high-assurance environments.

Based on the security policy that any publicly available server must be patched within 12 hours after a patch is released, the security analyst should patch Host 1 first. Here's why:
Public Availability: Host 1 is externally available, making it accessible from the internet. Publicly available servers are at higher risk of being targeted by attackers, especially when a zero-day vulnerability is known.
Exposure to Threats: Host 1 has IIS installed and is publicly accessible, increasing its exposure to potential exploitation. Patching this host first reduces the risk of a successful attack.
Prioritization of Critical Assets: According to best practices, assets that are exposed to higher risks should be prioritized for patching to mitigate potential threats promptly.

A Configuration Management Database (CMDB) provides the best foundation for identifying which specific assets are affected by a given vulnerability. A CMDB maintains detailed information about the IT environment, including hardware, software, configurations, and relationships between assets. This comprehensive view allows organizations to quickly identify and address vulnerabilities affecting specific assets.

DNS over HTTPS (DOH) encrypts DNS queries, which protects the browsing history from being monitored or intercepted by third parties, such as internet service providers or government authorities. This is especially important in countries where internet usage is closely monitored.
DOH ensures that DNS requests (which resolve domain names into IP addresses) are encrypted and sent over HTTPS, preventing external parties from seeing which websites the executive is visiting.

A secrets management tool is the most appropriate solution for securely managing and storing secrets (such as API keys, passwords, or tokens) in the new containerized environment. Secrets management tools, such as HashiCorp Vault, AWS Secrets Manager, or Azure Key Vault, provide secure storage, access control, and audit logs for secrets. They are designed to manage secrets in a way that avoids hardcoding sensitive data in configuration files or Dockerfiles, which could be exposed or compromised.
