Web UI

Package name: intrudect-web

The Web UI collects alerts from agents and provides search and export capabilities for the gathered data. It supports notification delivery via webhooks and e-mail, imports IOC data from MISP, and exports as JSON for Wazuh/Elastic.

Note

Command examples shown on page need to be executed in root shell

Note

If mariadb & rsyslog were installed as dependencies, they need to be enabled and started

systemctl --now enable mariadb
systemctl --now enable rsyslog

MaxMind GeoIP

Install

Setup

  • Create free account in https://www.maxmind.com/
  • Add your AccountID and License key into /etc/GeoIP.conf

    AccountID xxxx
    LicenseKey xxxx
    

  • Add Editions to /etc/GeoIP.conf:

    EditionIDs GeoLite2-Country GeoLite2-City GeoLite2-ASN
    

  • Execute geoipupdate (NB it will take 1-2 minutes for your maxmind AccountID and LicenseKey values to populate inside their infrastructure)
    geoipupdate -v
    
  • Add it to crontab as well
    ( crontab -l ; echo "30 05  *  *  * geoipupdate" ) | crontab -
    

Database setup

  • MariaDB server should be already installed as a depency.

  • Create database and user

    mysql
    
    MariaDB> CREATE DATABASE intrudect CHARACTER SET utf8mb4  COLLATE utf8mb4_unicode_ci;
    MariaDB> GRANT ALL PRIVILEGES ON intrudect.* TO 'intrudect'@'localhost' IDENTIFIED BY 'PASSWORD';
    MariaDB> FLUSH PRIVILEGES;
    

  • Allocate as much memory as possible to database.
    In /etc/mysql/mariadb.conf.d/50-server.cnf or /etc/my.cnf.d/mariadb-server.cnf (RedHat)

    [mysqld]
    max_allowed_packet=200M
    innodb_buffer_pool_size = XXG
    

  • Restart MariaDB server after config change

    systemctl restart mariadb.service
    

  • Ensure start on boot

    systemctl enable mariadb.service
    

  • Load timezone tables into MariaDB

    mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql
    
    Verify that output is > 0
    mysql -e 'SELECT COUNT(*) FROM mysql.time_zone;'
    +----------+
    | COUNT(*) |
    +----------+
    |      498 |
    +----------+
    

Configuration

Configuration file is in /opt/intrudect-web/config.json.

  • HOMEURL is used by agents to send alerts and request configuration changes.
  • LISTEN parameter specifies the IP address and port where the web UI listens, and you should forward your reverse proxy traffic to this location. Since the web UI itself does not have support for TLS, you must set up a reverse proxy, like Nginx or Caddy, in front of it in a production environment.

  • DB refers for MariaDB connection URI (refer to setup guide).

  • MISP is used to receive IOC data (such as domains and destination IP addresses) from a MISP server, which is queried once per hour for specified TAGS.
  • GEOIP folder of geoip database files (Ubuntu - /var/lib/GeoIP/, RedHat - /usr/share/GeoIP/)
  • HTTPS set to true when the web UI is behind a TLS-terminating reverse proxy. Ensures secure cookie flags and correct protocol handling.
  • REMOTEIP the HTTP header name that the reverse proxy uses to pass the client's real IP address (e.g. X-Real-Ip). Leave empty if not using a reverse proxy.
  • WEBAUTHN enables passkey/hardware key authentication. RPID is your domain name, RPORIGINS lists the allowed origins, and RPDISPLAYNAME is shown to users during registration.
  • LDAP enables Active Directory / LDAP authentication. When enabled, the login page shows a "Domain Login" tab alongside the local account login. See the AD/LDAP authentication section below for details.

AD/LDAP authentication

The web UI supports authenticating users against Active Directory or an LDAP server. When enabled, users see a "Domain Login" tab on the login page. Local account login remains available alongside domain login.

LDAP configuration fields

Field Description
Enabled Set to true to enable LDAP authentication.
URL LDAP server URL. Use ldaps:// for TLS (port 636) or ldap:// for plain (port 389).
BindPattern Template for constructing the bind identity. %s is replaced with the username. Use UPN format (%[email protected]) for Active Directory or DN format (uid=%s,ou=people,dc=example,dc=com) for OpenLDAP.
InsecureSkipVerify Skip TLS certificate verification. Set to false (default) to verify certificates, true to skip verification. Only use true for testing with self-signed certificates.
StartTLS Upgrade to TLS after connecting on a plain ldap:// connection. Has no effect when using ldaps://.
GroupPrefix Prefix for AD/LDAP group names that control access. The web UI checks membership in {prefix}-admins and {prefix}-users groups.
AutoProvision Automatically create a user account on first successful LDAP login. If set to false, an administrator must create the user locally before they can log in via LDAP.

Active Directory groups

Create two security groups in Active Directory matching your configured GroupPrefix:

  • {GroupPrefix}-admins — members receive full administrator permissions
  • {GroupPrefix}-users — members receive read-only permissions (except integrations)

For example, with "GroupPrefix": "intrudect", create groups intrudect-admins and intrudect-users. Users not in either group are denied access.

Note

Group membership is checked on every login. If a user's AD group membership changes (e.g. promoted from user to admin), the updated permissions take effect on their next login.

Example: Active Directory with LDAPS

"LDAP": {
    "Enabled": true,
    "URL": "ldaps://dc.corp.local:636",
    "BindPattern": "%[email protected]",
    "InsecureSkipVerify": false,
    "StartTLS": false,
    "GroupPrefix": "intrudect",
    "AutoProvision": true
}

Example: Active Directory with StartTLS

"LDAP": {
    "Enabled": true,
    "URL": "ldap://dc.corp.local:389",
    "BindPattern": "%[email protected]",
    "InsecureSkipVerify": false,
    "StartTLS": true,
    "GroupPrefix": "intrudect",
    "AutoProvision": true
}

Example: OpenLDAP with DN bind

"LDAP": {
    "Enabled": true,
    "URL": "ldaps://ldap.example.com:636",
    "BindPattern": "uid=%s,ou=people,dc=example,dc=com",
    "InsecureSkipVerify": false,
    "StartTLS": false,
    "GroupPrefix": "intrudect",
    "AutoProvision": true
}

Note

LDAP users can also enroll TOTP or WebAuthn as a second factor. When 2FA is configured, the user is prompted for their second factor after a successful domain login.

Start & enable service

systemctl restart intrudect-web
systemctl enable intrudect-web

Logfile

Web server writes additional info to /var/log/intrudect-web.log

Inital user

Before launching the web UI, an initial user and password must be created using the command-line utility.

cd /opt/intrudect-web
./intrudect-cli -cmd add -type admin -username <username> -password <passowrd>

Initial settings

  • Define network names and address ranges in "Site->Networks"
  • Review different module settings underr "Monitoring" menu.
  • Authorized DNS servers "Monitoring->DNS"
  • Authorized DHCP servers "Monitoring->DHCP"
  • Admin workstation addresses/subnets "Monitoring->Admin protocols"

  • Add alerting integrations under "Settings->Integrations"

Add agents

Point your browser to the web UI hostname and log in. Navigate to "Agents" and select the specific agent configuration from the menu.

After adding an agent, you can use "Download Config" to download its configuration file. This file now includes the agent’s login credentials for the web UI. Save the configuration file on the server where this particular agent is running.

download config

Configuration files are located at /opt/intrudect-<agentname>/etc/config.json

Adding external communication platforms

The web UI supports alert delivery to external channels via webhooks and e-mail. This allows users to receive real-time notifications based on their defined rules.

integrations

Wazuh integration (optional)

  • Install Wazuh agent into the server.
  • Append to /var/ossec/etc/ossec.conf

    <!-- intrudect -->
    <ossec_config>
      <localfile>
        <log_format>json</log_format>
        <location>/var/log/intrudect-wazuh.json</location>
      </localfile>
    </ossec_config>
    

  • Restart Wazuh agent

    systemctl restart wazuh-agent
    

  • On the Wazuh server, create a rule group and rules in the file: /var/ossec/etc/rules/local_rules.xml
    For example, one rule to catch all events:

    <group name="intrudect">
      <rule id="100010" level="12">
        <decoded_as>json</decoded_as>
        <field name="type">useragent</field>
        <description>$(description)</description>
      </rule>
    </group>
    
    Or multiple rules with custom levels:
    Possible TYPE values: honeypot,egress,dhcp,ioc,tor,arp,dns_txt,dns_ptr,dns_a,dns_aaaa,dns_dga,dns,ldap,portscan,smb,useragent,adm_protocol,newdevice,n2n,pwd_brute
    <group name="intrudect">
      <rule id="100010" level="12">
        <decoded_as>json</decoded_as>
        <field name="type">TYPE1</field>
        <description>$(description)</description>
      </rule>
      <rule id="100011" level="12">
        <decoded_as>json</decoded_as>
        <field name="type">TYPE2</field>
        <description>$(description)</description>
      </rule>
      / ... /
    </group>
    

  • Restart Wazuh

    systemctl restart wazuh-manager
