#SNORT RULES EXAMPLES CODE#
Enter our SQL injection code into the Search field and click “go”: You should see Web interface for the HttpFileServer 2.3b. In the address bar, enter the address of our HTTP server hosted on the Windows Server 2012 R2 VM: On your Kali Linux VM, open a web browser (go to Applications->Internet->Iceweasel Web Browser). Save the file and start Snort in IDS mode.
Patterns and specific formats are used not only for data that we are trying to protect. Can you write a rule looking for credit card numbers? Exercise 2: Detecting SQL injection You will see an alert generated by our rule. When logged on, transfer our file containing PII:Ĭheck your Snort output. Remember, the credentials are infosec/password$$$. Now, on your Kali Linux VM, open a terminal shell and connect to the FTP server on your Windows Server 2012 R2. Sudo snort -A console -q -c /etc/snort/nf -i eht0 Save the file and start Snort as root in IDS mode: The – parts escape the dashes so they will be included in the search.Now go to your Ubuntu Server VM and bring up the les file, or, if it’s closed, open it with a text editor as root:Īlert tcp any any -> any any (msg:”SSN in Clear Text” pcre:”/ quantifiers tell Snort to match ate least n, but not more than m times Add a fake Social Security Number to it, in the following format: XXX-XX-XXXX.

In this exercise, we will write a rule that looks for Social Security Numbers transmitted in plain text.įirst, let’s create some sensitive data to be transmitted. Luckily, most of the PII data has a specific format, which allows us to write rules for its monitoring.
PII (Personally Identifiable Information) is something you don’t want to be leaking out of your network.
