Install a Secure Event Connector on an AWS VPC Using a Terraform Module

Step 1

Go to Secure Event Connector Terraform Module on the Terraform Registry and follow the instructions to add the SEC Terraform module to your Terraform code.

Step 2

Apply the Terraform code.

Step 3

Ensure that you print the instance_id and sec_fqdn outputs, because you will need them later in the procedure.

Step 4

To enable sending of logs from your ASA to the SEC, obtain the certificate chain of the SEC you created and remove the leaf certificate by running the following command with the output from Step 3:

rm -f /tmp/cert_chain.pem && openssl s_client -showcerts -verify 5 -connect <FQDN>:10125 < /dev/null | awk '/BEGIN CERTIFICATE/,/END CERTIFICATE/{ if(/BEGIN CERTIFICATE/){a++}; out="/tmp/cert_chain.pem"; if(a > 1) print >>out}'

Step 5

Copy the contents of /tmp/cert_chain.pem to your clipboard.

Step 6

Take a note of the IP address of the SEC using the following command:

nslookup <FQDN>

Step 7

Log in to CDO and start adding a new trustpoint object. See Adding a Trusted CA Certificate Object for more information. Ensure you uncheck the Enable CA flag in basic constraints extension checkbox in Other Options before clicking Add.

Step 8

Click Add, copy the CLI commands generated by CDO in the Install Certificate page, and click Cancel.

Step 9

Below enrollment terminal, add no ca-check in a text clipboard.

Step 10

SSH into your ASA device or use the ASA CLI option in CDO and execute the following commands:

DataCenterFW-1> en
Password: *****************
DataCenterFW-1# conf t
DataCenterFW-1(config)# <paste your modified ASA CLIs here and press Enter>
DataCenterFW-1(config)# wr mem
