💥 Update breaks the plugin's normal operation!
To make it work, please read the Update instructions.
And there's live-chat in Telegram, for technical support use our Telegram live-chat: @ztcsupport
Оur plugin transforms your Zabbix monitoring system into vulnerability, risk and security managment system for your infrastructure.
It provides Zabbix with information about vulnerabilities existing in your entire infrastructure and suggests easily applicable remediation plans.
Information is displayed in Zabbix in the following format:
- Maximum CVSS score for each server.
- Command for fixing all detected vulnerabilities for each server.
- List of security bulletins with descriptions for vulnerable packages valid for your infrastructure.
- List of all vulnerable packages in your infrastructure.
Security bulletins and packages information includes:
- Impact index for the infrastructure.
- CVSS score of a package or a bulletin.
- Number of affected servers.
- A detailed list of affected hosts.
- Hyperlink to the description of a bulletin.
Sometimes it is impossible to update all packages on all servers to a version that fixes existing vulnerabilities. The proposed representation permits you to selectively update servers or packages.
This approach allows one to fix vulnerabilities using different strategies:
- all vulnerabilities on a specific server;
- a single vulnerability in the entire infrastructure.
This can be done directly from Zabbix (using its standard functionality) either on the administrator command or automatically.
- Using Zabbix API, the plugin receives lists of installed packages, names and versions of the OS from all the servers in the infrastructure (if the "Vulners OS-Report" template is linked with them).
- Transmits the data to Vulners
- Receives information on the vulnerabilities for each server.
- Processes the received information, aggregates it and sends it back to Zabbix via zabbix-sender.
- Finally the result is displayed in Zabbix.
On zabbix-server host:
- python 3 (only for ztc scripts)
- python modules: pyzabbix, jpath, requests, vulners
- zabbix version 3.4 is required to create a custom dashboard and a custom polling schedule.
- zabbix-sender utility for sending data to zabbix-server.
- zabbix-get utility for sending a command to fix vulnerabilities on the server.
On all the servers that require a vulnerability scan:
- zabbix-agent for collect data and run scripts.
rpm -Uhv https://repo.vulners.com/redhat/vulners-repo.rpm
On zabbix-server host:
yum install zabbix-threat-control-main zabbix-threat-control-host
On all the servers that require a vulnerability scan:
yum install zabbix-threat-control-host
wget https://repo.vulners.com/vulners-repo-py3.deb
dpkg -i vulners-repo-py3.deb
On zabbix-server host:
apt-get update && apt-get install zabbix-threat-control-main zabbix-threat-control-host
On all the servers that require a vulnerability scan:
apt-get update && apt-get install zabbix-threat-control-host
On zabbix-server host:
git clone https://github.com/vulnersCom/zabbix-threat-control.git
mkdir -p /opt/monitoring/zabbix-threat-control
cp -R zabbix-threat-control/os-report /opt/monitoring/
cp zabbix-threat-control/*.py /opt/monitoring/zabbix-threat-control/
cp zabbix-threat-control/*.conf /opt/monitoring/zabbix-threat-control/
chown -R zabbix:zabbix /opt/monitoring/
chmod 640 /opt/monitoring/zabbix-threat-control/*.conf
touch /var/log/zabbix-threat-control.log
chown zabbix:zabbix /var/log/zabbix-threat-control.log
chmod 664 /var/log/zabbix-threat-control.log
On all the servers that require a vulnerability scan:
git clone https://github.com/vulnersCom/zabbix-threat-control.git
mkdir -p /opt/monitoring/
cp -R zabbix-threat-control/os-report /opt/monitoring/
chown -R zabbix:zabbix /opt/monitoring/os-report
The configuration file is located here: /opt/monitoring/zabbix-threat-control/ztc.conf
To use Vulners API you need an api-key. To get it follow the steps bellow:
- Log in to vulners.com.
- Navigate to the userinfo space https://vulners.com/userinfo.
- Choose the "API KEYS" section.
- Select "scan" in the scope menu and click "Generate a new key".
- You will get an api-key, which looks like this: RGB9YPJG7CFAXP35PMDVYFFJPGZ9ZIRO1VGO9K9269B0K86K6XQQQR32O6007NUK
Now you need to add the Vulners api-key into your configuration file (parameter VulnersApiKey).
VulnersApiKey = RGB9YPJG7CFAXP35PMDVYFFJPGZ9ZIRO1VGO9K9269B0K86K6XQQQR32O6007NUK
In order to connect to Zabbix you need to specify the following in the configuration file:
- The URL, username and password. Note that the User should have rights to create groups, hosts and templates in Zabbix.
- Domain name and port of the Zabbix-server for pushing data using the zabbix-sender.
Here is an example of a valid config file:
ZabbixApiUser = yourlogin
ZabbixApiPassword = yourpassword
ZabbixFrontUrl = https://zabbixfront.yourdomain.com
ZabbixServerFQDN = zabbixserver.yourdomain.com
ZabbixServerPort = 10051
- To create all the necessary objects in Zabbix, run the
prepare.pyscript with parameters.
/opt/monitoring/zabbix-threat-control/prepare.py -uvtd
It will verify that zabbix-agent and zabbix-get utilities are configured correctly and create the following objects using Zabbix API:- A template used to collect data from servers.
- Zabbix hosts for obtaining data on vulnerabilities.
- An action to run the command fixes the vulnerability.
- A dashboard for displaying results.
- While using the Zabbix web interface, it is necessary to link the "Vulners OS-Report" template with the hosts that you are doing a vulnerabilities scan on.
Zabbix-agent must be able to execute remote commands. For this, change the parameters in the zabbix-agent configuration file /etc/zabbix/zabbix_agentd.conf:
EnableRemoteCommands=1
LogRemoteCommands=1
Zabbix-agent must be able to update packages as root. For this, add a line to the file /etc/sudoers:
zabbix ALL=(ALL) NOPASSWD: /usr/bin/yum -y update *
zabbix ALL=(ALL) NOPASSWD: /usr/bin/apt-get --assume-yes install --only-upgrade *
-
/opt/monitoring/os-report/report.py
Transfers the name, version and installed packages of the operating system to Zabbix.
Runs with zabbix-agent on all hosts to which the template "Vulners OS-Report" is linked. -
/opt/monitoring/zabbix-threat-control/scan.py
Processes raw data from zabbix and vulners and push them to the monitoring system using zabbix-sender.
Runs with zabbix-agent on the Zabbix server via the item "Service item" on the host "Vulners - Statistics".
The above scripts are run once a day. The start-up time is selected randomly during the installation and does not change during operation.
/opt/monitoring/zabbix-threat-control/fix.py
Runs commands to fix vulnerabilities on servers. It's executed as a remote command in the action "Vunlers" in Zabbix.
It will be ready soon...
