Snort in Pfsense
I am new with snort in pfsense, I just want to know if there are guidelines on the meaning of the alert description.
I am getting alert like:
SHELLCODE x86 inc ecx NOOP
ET POLICY PE EXE or DLL Windows file download
I am not sure if this description is a valid attack or not, basically how do I know if someone is trying to access our network or is snort well configured to prevent other person from unauthorized access.
I do apologized for the ignorance hoping someone will explain and give me more detailed explanation on how to use the snort in pfsense for auditing and preventing attacks on the network.
