🚨 Suricata Alert Report — IDS/IPS Alert Analysis / Suricata 告警分析报告

Free tier · Enterprise AI Agent upgrades at kingai.work

My Understanding / 我的理解

EN: This skill reads Suricata IDS/IPS alert logs from eve.json (or rotated eve.json.* gz files) in /var/log/suricata/, aggregates them by severity (1=Critical, 2=High, 3=Medium, 4=Low), identifies the top source IPs and top alert signatures, and produces a Chinese-language incident briefing. It also checks if Suricata is running and reports engine stats, packet processing rates, and interface status.

CN: 该技能读取 Suricata IDS/IPS 告警日志（/var/log/suricata/eve.json 或其轮转 eve.json.* gz 文件），按严重级别（1=严重、2=高、3=中、4=低）聚合告警，识别 TOP 源 IP 地址和 TOP 告警签名，并生成中文事件简报。同时检查 Suricata 运行状态，报告引擎统计信息、数据包处理速率和接口状态。

Design Philosophy / 设计理念

EN: "Aggregate to reveal, prioritize to act." Raw alert logs are noisy — a single scanning IP can generate thousands of identical alerts. The skill aggregates: same sig → one line with count. It ranks by severity × frequency so a high-frequency severity-1 alert is surfaced first. Twenty-four-hour windows give context; the skill checks if Suricata is live and processing traffic before trusting the log contents.

CN： "聚合以揭示，分级以行动。" 原始的告警日志噪音很大 — 一个扫描 IP 就能产生成千上万条相同的告警。该技能进行聚合：相同签名 → 一行加计数。按严重级别 × 频率排序，使高频次的 1 级告警优先显示。使用 24 小时窗口提供上下文；在信任日志内容之前，会检查 Suricata 是否正在运行并处理流量。

Check / Diagnostic Commands & Scoring

bash

# 1. Check Suricata service status (score: 1 pt)
systemctl is-active suricata

# 2. Suricata engine stats (score: 2 pts) — verify it's processing packets
suricatasc -c "stats" 2>/dev/null | head -40 || suricata --dump-stats 2>/dev/null

# 3. Count total alerts in current eve.json (score: 2 pts)
jq -c 'select(.event_type=="alert")' /var/log/suricata/eve.json 2>/dev/null | wc -l

# 4. Alerts by severity (score: 2 pts) — CORE
jq -r 'select(.event_type=="alert") | .alert.severity' /var/log/suricata/eve.json 2>/dev/null | sort | uniq -c | sort -rn

# 5. Top 10 alert signatures (score: 1 pt)
jq -r 'select(.event_type=="alert") | .alert.signature' /var/log/suricata/eve.json 2>/dev/null | sort | uniq -c | sort -rn | head -10

# 6. Top 10 source IPs (score: 1 pt)
jq -r 'select(.event_type=="alert") | .src_ip' /var/log/suricata/eve.json 2>/dev/null | sort | uniq -c | sort -rn | head -10

# 7. Check rotated logs for older alerts (score: 1 pt)
for f in /var/log/suricata/eve.json.*.gz; do
  [ -f "$f" ] && zgrep -c '"event_type":"alert"' "$f" 2>/dev/null
done

# 8. Count alerts per category (score: 0.5 pt)
jq -r 'select(.event_type=="alert") | .alert.category' /var/log/suricata/eve.json 2>/dev/null | sort | uniq -c | sort -rn

# 9. Protocol breakdown of alerts (score: 0.5 pt)
jq -r 'select(.event_type=="alert") | .proto' /var/log/suricata/eve.json 2>/dev/null | sort | uniq -c | sort -rn

Health score: /10 — 3 pts deducted if Suricata is inactive; 1 pt deducted if eve.json is missing or empty; 2 pts bonus if alerts are found AND categorized with clear attack patterns.
