🔐 Security Hardening

🛡️ Security Best Practices:

#!/bin/bash
# IntegrityGuard Pro Security Hardening Script

# 1. Create dedicated user and group
sudo useradd -r -s /bin/false integrityguard
sudo groupadd integrityguard-admin

# 2. Set file permissions
sudo chown -R integrityguard:integrityguard /opt/integrityguard
sudo chmod 750 /opt/integrityguard
sudo chmod 640 /opt/integrityguard/config/*.yaml
sudo chmod 600 /opt/integrityguard/ssl/*.pem

# 3. Configure systemd service with security restrictions
sudo tee /etc/systemd/system/integrityguard.service > /dev/null <<EOF
[Unit]
Description=IntegrityGuard Pro - File Integrity Monitoring
After=network.target postgresql.service redis.service
Wants=postgresql.service redis.service

[Service]
Type=notify
User=integrityguard
Group=integrityguard

LimitNPROC=4096
MemoryMax=4G
CPUQuota=400%

[Install]
WantedBy=multi-user.target
EOF

# 4. Configure firewall rules
sudo ufw allow from 10.0.0.0/8 to any port 8080 comment 'IntegrityGuard Web Interface'
sudo ufw allow from 10.0.0.0/8 to any port 8443 comment 'IntegrityGuard Secure API'
sudo ufw deny 8080 comment 'Block external access to web interface'
sudo ufw deny 8443 comment 'Block external access to API'

# 5. Set up log rotation
sudo tee /etc/logrotate.d/integrityguard > /dev/null <<EOF
/opt/integrityguard/logs/*.log {
    daily
    rotate 30
    compress
    delaycompress
    missingok
    notifempty
    sharedscripts
    postrotate
        systemctl reload integrityguard
    endscript
}
EOF

# 6. Configure fail2ban for brute force protection
sudo tee /etc/fail2ban/jail.d/integrityguard.conf > /dev/null <<EOF
[integrityguard]
enabled = true
port = 8080,8443
filter = integrityguard
logpath = /opt/integrityguard/logs/access.log
maxretry = 3
bantime = 3600

EOF

# 7. Enable and start services
sudo systemctl daemon-reload
sudo systemctl enable integrityguard
sudo systemctl start integrityguard
sudo systemctl enable fail2ban
sudo systemctl restart fail2ban

    real_time_monitoring=True
)

# Create monitoring instance
monitor = IntegrityMonitor(config)

# Add paths to monitor
monitor.add_path(
    path='/critical/database',
    priority='critical',
    recursive=True,
