Our infrastructure team plans to deploy active inline firewall blocking to prevent external threat actors from inspecting user-agent headers and scanning public host profiles before an attack. Is active preventive blocking the recommended mitigation ID and strategy for T1592?

Adversaries may gather information about the victim's hosts that can be used during targeting. Information about hosts may include a variety of details, including administrative data (ex: name, assigned IP, functionality, etc.) as well as specifics regarding its configuration (ex: operating system, language, etc.).
Adversaries may gather this information in various ways, such as direct collection actions via Active Scanning or Phishing for Information. Adversaries may also compromise sites then include malicious content designed to collect host information from visitors. Information about hosts may also be exposed to adversaries via online or other accessible data sets (ex: Social Media or Search Victim-Owned Websites). Gathering this information may reveal opportunities for other forms of reconnaissance (ex: Search Open Websites/Domains or Search Open Technical Databases), establishing operational resources (ex: Develop Capabilities or Obtain Capabilities), and/or initial access (ex: Supply Chain Compromise or External Remote Services).
Adversaries may also gather victim host information via User-Agent HTTP headers, which are sent to a server to identify the application, operating system, vendor, and/or version of the requesting user agent. This can be used to inform the adversary’s follow-on action. For example, adversaries may check user agents for the requesting operating system, then only serve malware for target operating systems while ignoring others.
Platforms: PRE
Identify Attack Surface: Determine if the target environment is susceptible to Gather Victim Host Information by examining the target platforms (PRE).
Assess Existing Defenses: Review whether mitigations for T1592 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.
Note: No Atomic Red Team tests available for this technique. See Atomic Red Team GitHub for updates.
This technique cannot be easily mitigated with preventive controls since it is based on behaviors performed outside of the scope of enterprise defenses and controls. Efforts should focus on minimizing the amount and sensitivity of data available to external parties.
