CAPEC 描述
An adversary sends out an ICMP Type 8 Echo Request, commonly known as a 'Ping', in order to determine if a target system is responsive. If the request is not blocked by a firewall or ACL, the target host will respond with an ICMP Type 0 Echo Reply datagram. This type of exchange is usually referred to as a 'Ping' due to the Ping utility present in almost all operating systems. Ping, as commonly implemented, allows a user to test for alive hosts, measure round-trip time, and measure the percentage of packet loss.
CAPEC 資訊
前置條件
The ability to send an ICMP type 8 query (Echo Request) to a remote target and receive an ICMP type 0 message (ICMP Echo Reply) in response. Any firewalls or access control lists between the sender and receiver must allow ICMP Type 8 and ICMP Type 0 messages in order for a ping operation to succeed.所需技能
The adversary needs to know certain linux commands for this type of attack.所需資源
Scanners or utilities that provide the ability to send custom ICMP queries.緩解措施
Consider configuring firewall rules to block ICMP Echo requests and prevent replies. If not practical, monitor and consider action when a system has fast and a repeated pattern of requests that move incrementally through port numbers.相關弱點
