Adversaries may gather information about the victim's network topology that can be used during targeting. Information about network topologies may include a variety of details, including the physical and/or logical arrangement of both external-facing and internal network environments. This information may also include specifics regarding network devices (gateways, routers, etc.) and other infrastructure.
Adversaries may gather this information in various ways, such as direct collection actions via Active Scanning or Phishing for Information. Information about network topologies may also be exposed to adversaries via online or other accessible data sets (ex: Search Victim-Owned Websites).(Citation: DNS Dumpster) Gathering this information may reveal opportunities for other forms of reconnaissance (ex: Search Open Technical Databases or Search Open Websites/Domains), establishing operational resources (ex: Acquire Infrastructure or Compromise Infrastructure), and/or initial access (ex: External Remote Services).

Comments
VPC security groups and network access control lists (NACLs) can prevent the gathering of victim network information via (active) scanning methods but is not effective against other methods of gathering victim network information such as via Phishing or online databases (e.g. WHOIS) resulting in a Partial coverage score and an overall Partial score.

Comments
AWS Security Hub detects improperly secured data from S3 buckets such as public read and write access that may result in an adversary getting access to information that could be used during targeting. AWS Security Hub provides these detections with the following managed insights.
S3 buckets with public write or read permissions S3 buckets with sensitive data
This is scored as Minimal because S3 only represents one of many available sources of information that an adversary could use for targeting.

Comments
AWS Network Firewall has the ability to pass, drop, or alert on traffic based on the network protocol as well as perform deep packet inspection on the payload. This functionality can be used to restrict access to the endpoints within the virtual private cloud and protect against adversaries gathering information about the network. This mapping is given a score of Partial because it only protects against attempts to gather information via scanning that originate from outside the firewall and it does not protect against phishing.
