    I am using Symantec Endpoint Protection Manager 11 MR4.
    Is there a way to create custom intrusion prevention signature to prevent machines from sending ICMP broadcast traffic ?

    Thanks & Regards,
    Ash

    Hi,

    the answer to your  question is that you cannot create custom IPS.
    Did you try to create a proper firewall rule in our firewall?

    Regards,

     When you write the content for each IPS signature, you must use the following syntax:

    rule protocol-type, [protocol-options,] [ip-protocol options,] msg, content...

    ICMP protocol arguments

    Refer to RFCs 792 and 1256 for detailed descriptions of valid ICMP protocol type and code combinations.

    Table: ICMP protocol arguments

    Attribute
    Description
    Syntax
    type
    ICMP protocol type
    type operator value
    where value is an unsigned 8-bit number from 0 to 255.
    For example:type=0
    code
    ICMP protocol type
    code operator value
    where value is an unsigned 8-bit number from 0 to 255.
    For example:
    code<=10

    This can be done via Firewall aswell.
    When you create a firewall rule for Netowrk Service rule ..next..next..finish..
    double click Service -ADD...select ICMP and you get all the 40 ICMP type to block or allow.
