Ping is a fundamental network utility that helps users determine the availability and response time of a target device, such as a computer, server, or network device, by sending small packets of data to it. It operates on the Internet Control Message Protocol (ICMP) and forms an essential part of the incident response and discovery toolkit in cyber security.

How Ping Works

When you issue a Ping command, your device sends out ICMP Echo Request packets to the target device. In response, the target device sends out ICMP Echo Reply packets. The round-trip time (RTT) between the request and reply is measured and reported, which is an indication of the network latency and helps identify network problems.

Uses of Ping in Cyber Security

Ping Limitations

Despite these limitations, Ping remains a useful tool in the cyber security world for network diagnostics and incident response. However, it is essential to use Ping in conjunction with other discovery tools and network analysis techniques for comprehensive network assessments.
