Explanation
According to the [CrowdStrike website], the Discover page is where you can search for and analyze various types of indicators of compromise (IOCs), such as hashes, IP addresses, or domains that are associated with malicious activities. You can use various tools, such as Hash Executions, IP Addresses, Remote or Network Logon Activity, etc., to perform different types of searches and view the results in different ways. If you want to search for any activity related to an IP address that was compromised by a third-party vendor, you can use the IP Addresses tool to do so. You can input the IP address and see a summary of information from Falcon events that contain that IP address, such as hostname, sensor ID, OS, country, city, ISP, ASN, geolocation, process name, command line, and organizational unit of the host that communicated with that IP address.

Explanation
According to the CrowdStrike Falcon Data Replicator (FDR) Add-on for Splunk Guide, you can use the Hosts page in the Investigate tool to view information about your endpoints, such as hostname, IP address, OS, sensor version, etc2. You can also see a list of managed and unmanaged neighbors for each endpoint, which are other devices that have communicated with that endpoint over the network2. A managed neighbor is a device that has an installed and provisioned sensor that reports to the CrowdStrike Cloud2. An unmanaged neighbor is a device that does not have an installed or provisioned sensor2.

Explanation
According to the [MITRE ATT&CK website], MITRE ATT&CK is a knowledge base of adversary behaviors and techniques based on real-world observations. The knowledge base is organized into tactics and techniques, where tactics are the high-level goals of an adversary, such as initial access, persistence, lateral movement, etc., and techniques are the specific ways an adversary can achieve those goals, such as phishing, credential dumping, remote file copy, etc. The knowledge base also covers different platforms that adversaries target, such as Windows, Linux, Mac, Android, iOS, etc., and different phases of an adversary's lifecycle, such as reconnaissance, resource development, execution, command and control, etc.
