Description

The remote ICCP server has just sent an ACSE Abort Message in response to an invalid Presentation Layer Selector (PSEL) value. As PSEL values are typically only 2 to 4 bytes long, this could indicate that a client is 'brute-forcing' a valid PSEL value. This sort of attack can also impact Availability to the server.
