What’s the best 스포츠중계 way to monitor real-time authentication failures and block suspicious IPs?

To defend your exposed NGINX services from brute force attacks, credential stuffing, or bot probes, you need real-time monitoring and automated blocking of malicious IPs. The most effective setup combines log analysis tools, rate-limiting triggers, and IP banning systems that work seamlessly together.

Here’s a step-by-step strategy that detects, reacts, and protects in real time:

---

✅ 1. Use Fail2Ban for NGINX Log Monitoring and IP Banning

Fail2Ban is a lightweight security daemon that scans logs for failed logins, excessive requests, or suspicious patterns — then automatically blocks the offending IP using firewall rules.

???? How to Set It Up:

Step 1: Install Fail2Ban

bash

복사편집

sudo apt update sudo apt install fail2ban

Step 2: Create a Custom Filter for NGINX Auth

File: /etc/fail2ban/filter.d/nginx-auth.conf

ini

복사편집

[Definition] failregex = no user/password was provided for basic authentication.*client: <HOST> ignoreregex =

Step 3: Add a Jail for NGINX

File: /etc/fail2ban/jail.local

ini

복사편집

[nginx-auth] enabled = true port = http,https filter = nginx-auth logpath = /var/log/nginx/error.log maxretry = 5 bantime = 3600 findtime = 600

This bans IPs with 5 failed login attempts in 10 minutes for 1 hour.

Restart Fail2Ban:

bash

복사편집

sudo systemctl restart fail2ban

✅ 2. Monitor Logs in Real-Time with GoAccess or Logwatch

???? GoAccess – Terminal-Based Real-Time Log Analyzer

• Install:

  bash

  복사편집

  sudo apt install goaccess

• Run live view:

  bash

  복사편집

  goaccess /var/log/nginx/access.log -c

• Shows IPs, URLs, status codes, geolocation, user agents — all in real-time.

???? Logwatch – Daily Summary of Suspicious Activity

• Sends email alerts summarizing login failures, 404 spam, and request anomalies.

---

✅ 3. Block Malicious 스포츠중계 IPs with GeoIP or IP Sets

Use ngx_http_geoip_module or an external blocklist:

• Deny known botnet countries or ranges (e.g., Russia, China)

• Block using country code:

nginx

복사편집

geoip_country /usr/share/GeoIP/GeoIP.dat; map $geoip_country_code $allowed_country { default no; US yes; } server { if ($allowed_country = no) { return 403; } }

• You can also auto-ban IPs from blocklists like:

  • AbuseIPDB

  • FireHOL IP Lists

---

✅ 4. Watch for Port Scans and Recon with CrowdSec

CrowdSec is a modern Fail2Ban alternative with community-driven IP reputation intelligence.

• Detects brute force, scanning, credential stuffing

• Blocks IPs with shared threat intelligence

• Can protect SSH, HTTP, Plex, and more

Install with:

bash

복사편집

curl -s https://install.crowdsec.net | bash

Pair with NGINX bouncer to auto-ban offenders at the web level.

???? Real-Time Alerting (Optional Add-Ons)

• Uptime Kuma: Self-hosted uptime & alert system

• Grafana + Loki + Promtail: Beautiful dashboards of your NGINX logs

• Slack/Webhook Integration: Send alerts on failed login spikes or bans

---

???? Summary: Harden + Watch + React
