ModSecurity, sometimes called Modsec, is an open-source web application firewall. This integration allows you to send ModSecurity logs to your Logz.io SIEM account.
Before you begin, you’ll need:
- Apache2 Web Server and Terminal access to the instance running it
- ModSecurity module installed
- OWASP ModSecurity Core Rule Set (CRS) imported
- Filebeat 7 installed
##### Download the Logz.io public certificate to your credentials server
For HTTPS shipping, download the Logz.io public certificate to your certificate authority folder.
sudo curl https://raw.githubusercontent.com/logzio/public-certificates/master/AAACertificateServices.crt --create-dirs -o /etc/pki/tls/certs/AAACertificateServices.crt
Open the Filebeat configuration file (/etc/filebeat/filebeat.yml) with your preferred text editor. Copy and paste the code block below, overwriting the previous contents. (You want to replace the file’s contents with this code block.)
### Filebeat ### filebeat.inputs: - type: log paths: - /var/log/apache2/error.log fields: logzio_codec: json token: <<LOG-SHIPPING-TOKEN>> type: modsecurity fields_under_root: true encoding: utf-8 ignore_older: 3h #For version 6.x and lower #filebeat.registry_file: /var/lib/filebeat/registry # For version 7 and higher filebeat.registry.path: /var/lib/filebeat # The following processors are to ensure compatibility with version 7 processors: - rename: fields: - from: "agent" to: "beat_agent" ignore_missing: true - rename: fields: - from: "log.file.path" to: "source" ignore_missing: true ### Output ### output: logstash: hosts: ["<<LISTENER-HOST>>:5015"] ssl: certificate_authorities: ['/etc/pki/tls/certs/COMODORSADomainValidationSecureServerCA.crt']
Replace the placeholders to match your specifics. (They are indicated by the double angle brackets
<<LOG-SHIPPING-TOKEN>>with the token of the account you want to ship to.
<<LISTENER-HOST>>with the host for your region. For example,
listener.logz.ioif your account is hosted on AWS US East, or
listener-nl.logz.ioif hosted on Azure West Europe.
One last validation - make sure Logz.io is the only output and appears only once. If the file has other outputs, remove them.
Start or restart Filebeat for the changes to take effect.
Check Logz.io for your logs
Give your logs some time to get from your system to ours, and then open Kibana.
