Configuration

Importing CA certificates

The module tries to verify certificates using its own trust store. By default, this trust store is empty, and it is up to the Icinga Web 2 admin to import CA certificates into it.

Using the icingacli x509 import command CA certificates can be imported. The certificate chain file that is specified with the --file option should contain a PEM-encoded list of X.509 certificates which should be added to the trust store:

icingacli x509 import --file /etc/ssl/certs/ca-certificates.crt

Configure Jobs

Scan jobs have a name which uniquely identifies them, e.g. lan. These names are used by the CLI command to start scanning for specific jobs.

Each scan job can have one or more IP address ranges and one or more port ranges. The module scans each port in a job's port ranges for all the individual IP addresses in the IP ranges. IP address ranges have to be specified using the CIDR format. Multiple IP address ranges can be separated with commas, e.g.:

192.0.2.0/24,10.0.10.0/24

Port ranges are separated with dashes (-). If you only want to scan a single port you don't need to specify the second port:

443,5665-5669

Additionally, each job may also exclude specific hosts and IP addresses from scan. These hosts won't be scanned when you run the scan or jobs command. Excluding an entire network and specifying IP addresses in CIDR format will not work. You must specify concrete IPs and host CNs separated with commas, e.g:

192.0.2.2,192.0.2.5,icinga.com

Job Schedules

Schedules are cron and rule based configs used to run jobs periodically at the given interval. Every job is allowed to have multiple schedules that can be run independently of each other. Each job schedule provides different options that you can use to control the scheduling behavior of the jobs command.

Examples

A schedule that runs weekly on Friday and scans all targets that have not yet been scanned, or whose last scan is older than 1 week.

Weekly Schedules

Server Name Indication

In case you are serving multiple virtual hosts under a single IP you can configure those in Configuration -> Modules -> x509 -> SNI.

Each entry defines an IP with multiple hostnames associated with it. These are then utilized when jobs run.

Modules may also provide sources for SNI. At this time the module monitoring is the only one with known support.

Icinga Certificate Monitoring Daemon

The default systemd service of this module, shipped with package installations, uses the jobs command and runs all your configured jobs and schedules.

Note

If you haven't installed this module from packages, you have to configure this as a systemd service yourself by just copying the example service definition from /usr/share/icingaweb2/modules/x509/config/systemd/icinga-x509.service to /etc/systemd/system/icinga-x509.service.

You can run the following command to enable and start the daemon.

systemctl enable --now icinga-x509.service
