Local Guard Security Setup Guide

Learn how to configure and manage Local Guard, a self-security enhancement module operating within individual servers.

📋 Overview

Local Guard is a security-specialized sub-module of the GIIP agent that monitors abnormal signs occurring within the server itself, independent of network security. It functions as a Host-based Intrusion Prevention System (HIPS).

🛠️ Key Security Features

1. Login Auditing

  • Records all SSH and local login attempts.
  • Specifically tracks direct logins to the
    root
    account or repeated attempts at short intervals in real-time.

2. Critical File Protection

  • Originally blocks or immediately sends warnings for modification attempts on core system files such as
    /etc/shadow
    or
    C:\Windows\System32\config
    .

3. Local Firewall Policy Integration

  • Immediately reflects security policies set in the GIIP console to the corresponding server's
    iptables
    or Windows Firewall to block access from unauthorized IPs.

🔍 Configuration & Operation

  • Activation Status: You can toggle the operation status of Local Guard On/Off in the [Server Detail] > [Security Settings] tab.
  • Exception Handling: Register actions of backup programs or antivirus software modifying files in the 'Whitelist' to prevent false positives.

⚠️ Emergency Response

When an intrusion attempt is detected by Local Guard, the following actions are possible:

  • Force Session Termination: Immediately disconnect the terminal session being used by the attacker.
  • Permanent IP Block: Register the attacker's source IP in a blacklist to prevent access from all servers belonging to the project.

💡 Important Notes

  • Enabling the Local Guard feature may consume a small amount of additional system resources (less than 1% CPU).
