Store Certificates on Gateway
When a certificate is renewed, you must update the certificate according to the instructions below, then enforce policy again (even if configuration has not changed) by clicking on "Enforce" on the top bar of the web administration application for CloudGuard AppSec in the portal, or by using management API.
In order to use encrypted traffic (HTTPS) a managed reverse proxy must have access to the relevant certificates of the domains and URLs it exposes.
Example - you have two applications and one API endpoint to protect:
- www.acme.com
- www.acme.com/sales
- products.acme.com/catalog
Examples | Certificates used | Required action |
|---|---|---|
Case 1 | You have one wildcard certificate for *.acme.com | Place the certificate in the desired certificate storage by following the instructions below. AppSec will use it for all relevant applications |
Case 2 | You have two certificates: (1) for www.acme.com and (2) for products.acme.com | Place both certificates in the desired certificate storage by following the instructions below. AppSec will automatically use certificate 1 for the first two Applications/APIs and certificate 2 for the last Application |
Follow these steps to store your certificate and private keys on the gateway that can be used by CloudGuard AppSec to process HTTPS traffic:
- Advantage: you have full control of your secrets
- Disadvantage: does not support automatic scaling
The tool's purpose is to verify the certificate and key files and generate an output .pkg file with a unique name.
or run:
wget https://sc1.checkpoint.com/nano-agent/certverify/linux/certverify && chmod +x certverify You can use this tool on any machine where you have the files, before you actually store them on your CloudGuard AppSec Gateway(s).
Linux and Mac:
- PEM certificates:
./certverify --cert {certificate.pem} --key {private-key.key} - PFX certificates: .
/certverify --cert {certificate.pfx} --pass {password}
Windows:
- PEM certificates :
certverify --cert {certificate.pem} --key {private-key.key} - PFX certificates :
certverify --cert {certificate.pfx} --pass {password}
Repeat this step for each certificate/private key you wish to use.
Only certificates that contain Subject Alternative Name (SAN) are supported.
The tool will verify the certificate and key files, and generate an output .pkg file with a unique name that includes both.
Step 3: Store certificate and private key on your AppSec Gateway using SCP
You must store the files in directory /etc/certs on the AppSec Gateway or else they will not be identified.
If the commands below end with an error, navigate to /etc and make sure a directory exists called "certs" (in linux, use the
mkdir command).The input pkg file for this step is the uniquely named pkg output file of the previous step.
- Linux or Mac:
./scp {unique-name.pkg} admin@{gateway-ip}:/etc/certs - Windows:
"C:\Program Files (x86)\WinSCP\WinSCP.com" /command "open scp://admin:{password}@{gateway-ip}" "put cert_cert.pkg /etc/certs/" "exit"
Repeat this step for each certificate/private key you wish to use and for each AppSec Gateway.
AppSec will now use the relevant certificates with HTTPS clients that are trying to access your applications.
You can now change your DNS entries as relevant to point to your AppSec Gateway IP or to a Load Balancer in front of several AppSec Gateways.
