How to use ICMP and Ping

[Robert59]

I need some information on using up icmp and ping in catching my network threats. How to use this and what are they actually. If I apply the same then by what mean I can get proper support for this terms to get rid of major threats on the network. Also post some tips for getting additional information on the services on the network.

Here is a small piece of information in sequence on ICMP and Ping. ICMP positions for Internet Control Message Protocol, one of the most significant protocols part of the Internet protocol collection. The function of ICMP is to send ICMP requirements and obtain superior provision messages and error messages. Fundamentally, ICMP packets are being sent to an isolated system or router, and the system might respond with an additional ICMP packet, and consequently the status of this system our router can be confirmed. Of course, there are additional uses of ICMP, including momentarily modifying routes for network packets and supplementary.

You have to Ping, on the additional hand, is an usefulness that can be used to send ICMP Echo application messages to a isolated system and conclude whether the system is energetic and also confirm the dependability of the correlation, based on ICMP Echo response messages expected, and from side to side measuring the time it takes for network packets to get to that inaccessible host and backwards.

The ICMP protocol is not a sanctuary difficulty by itself; on the other hand it can present an attacker with supplementary information in sequent regarding a system. Fundamentally, an attacker can utilize ICMP to ping remote systems and conclude whether they are active or not. You might desire to put out of action ICMP absolutely on your external IP address, so your system does no longer answer to ICMP messages from the Internet, and in this method you can secrete your system occurrence, at least via the ICMP protocol.

On the other hand, please make a note of that ICMP Echo messages are used by several ISP's for mechanical confirmation of Internet correlation position for their clients, and therefore this might interfere with mechanical monitoring of your Internet correlation and you might accept calls from your ISP as to finding out what's incorrect with your correlation.

In the above cases, you may ask your ISP which are the IP ranges used for their monitoring tools, and then disable ICMP for everyone but those IP ranges, through a special added rule in your firewall. Please note that ICMP redirects are sometimes used to get access to other networks through your local network; it is recommended to disable ICMP redirect on Windows machines, an option that is enabled by default in all Windows installations.
