从Vault动态注入禁止硬编码 organization secops bucket metrics [[inputs.exec]] commands [/usr/local/bin/get_device_health.sh] timeout 30s data_format influx # 关键通过环境变量注入设备唯一标识用于后续关联CMDB environment [DEVICE_ID{{.Env.SERIAL_NUMBER}}, MANAGE_IP{{.Env.MANAGE_IP}}] # 启用TLS双向认证 [[outputs.influxdb_v2.tls_config]] ca /etc/telegraf/certs/ca.pem cert /etc/telegraf/certs/client.pem key /etc/telegraf/certs/client.key insecure_skip_verify false # 绝对禁止设为true提示get_device_health.sh脚本需根据设备类型定制例如对Linux服务器执行uptime; df -h; ss -tuln | wc -l对华为交换机则调用curl -k -X GET https://{{.Env.MANAGE_IP}}/restconf/data/huawei-aaa:aaa-statistics -H Authorization: Bearer $TOKEN。所有敏感凭证如RESTCONF Token通过HashiCorp Vault动态注入避免写入脚本。2.2 用InfluxDB Schema设计实现指标溯源InfluxDB 2.x默认不校验字段类型易导致cpu_usage存成字符串引发告警失效。我们在bucket中强制启用schema约束并为每个指标添加device_id、collect_time、collector_version标签# 创建带Schema约束的bucket influx bucket create \ --name metrics \ --org secops \ --retention 90d # 定义measurement schema需InfluxDB Enterprise或OSS 2.7 influx schema update \ --bucket-id 0xAbC123... \ --file /tmp/metrics_schema.yaml/tmp/metrics_schema.yaml内容measurements: - name: system_cpu tags: - name: device_id type: string required: true - name: collector_ip type: string required: true fields: - name: usage_percent type: float required: true - name: core_count type: integer required: true retention_policy: 90d参数说明device_id必须与CMDB中资产ID完全一致如HW-SW-2023-001collector_ip记录Telegraf所在主机IP用于快速定位采集源异常。usage_percent设为float而非string避免Grafana面板计算错误。2.3 Grafana告警规则绑定资产生命周期告警不能只说“CPU90%”必须关联资产状态。我们在Grafana中创建告警规则时强制关联CMDB API-- 在Grafana Alert Rule的Query中 SELECT mean(usage_percent) AS value FROM system_cpu WHERE (device_id ~ /^$device_id$/) AND time now() - 5m GROUP BY time(1m) HAVING mean(usage_percent) 90.0 -- 关联CMDB获取资产责任人 -- 调用CMDB API: GET https://cmdb.example.com/api/v1/assets?device_id${device_id} -- 返回JSON含: {owner: zhangsandept.example.com, env: prod, status: online}逻辑说明当告警触发时Grafana自动将owner邮箱填入通知模板并根据env字段决定是否升级至值班经理envprod时触发二级通知。statusoffline的设备自动屏蔽告警避免误报。3. 日志归集层用FilebeatLogstash双缓冲抗住万级EPS拒绝日志丢失黑洞很多方案用rsyslog直发ELK看似简单但遇到网络抖动或ES集群GC暂停日志直接丢弃——攻防演练时红队爆破产生的万级auth.log瞬间涌入rsyslog队列溢出关键攻击链断片。我们必须构建带双缓冲的日志管道Filebeat本地磁盘缓冲 Logstash内存Redis队列缓冲确保任何环节故障都不丢日志。3.1 Filebeat配置磁盘缓冲与断连重试filebeat.yml核心配置版本8.12filebeat.inputs: - type: filestream enabled: true paths: - /var/log/auth.log - /var/log/syslog - /opt/app/logs/*.log tags: [security] processors: - add_host_metadata: ~ - add_fields: target: fields: collector_type: filebeat env: prod output.logstash: hosts: [logstash1.example.com:5044, logstash2.example.com:5044] loadbalance: true # 关键启用磁盘缓冲最大1GB避免内存OOM bulk_max_size: 2048 queue: spool: type: disk path: /var/lib/filebeat/spool max_bytes: 1073741824 # 1GB max_events: 100000 retry: enabled: true backoff: 1s max_attempts: 10 jitter: true # 故障转移当Logstash全挂自动切到Redis备用通道 output.redis: hosts: [redis-cluster.example.com:6379] key: filebeat_backup db: 0 timeout: 30s ssl: enabled: true certificate_authorities: [/etc/filebeat/certs/ca.pem]注意spool路径必须挂载独立磁盘分区如/var/lib/filebeat/spool单独挂/dev/sdb1避免占满根分区导致系统崩溃。max_attempts10配合backoff1s确保网络恢复后日志自动续传。3.2 Logstash双队列设计内存队列保实时Redis队列保持久logstash.conf配置双输入源优先消费Filebeat直连故障时自动切换Redisinput { # 主通道接收Filebeat TLS加密数据 beats { port 5044 ssl true ssl_certificate /etc/logstash/certs/server.crt ssl_key /etc/logstash/certs/server.key ssl_certificate_authorities [/etc/logstash/certs/ca.pem] } # 备通道从Redis读取Filebeat备份日志 redis { host redis-cluster.example.com port 6379 db 0 key filebeat_backup data_type list codec json ssl true ssl_certificate_authorities [/etc/logstash/certs/ca.pem] } } filter { if [log][file][path] ~ auth.log { grok { match { message %{SYSLOGTIMESTAMP:timestamp} %{HOSTNAME:hostname} sshd\[%{NUMBER:pid}\]: %{DATA:event_type}: %{DATA:user} from %{IP:src_ip} port %{NUMBER:src_port} %{GREEDYDATA:details} } tag_on_failure [_grokparsefailure_auth] } geoip { source src_ip } } } output { # 主输出写入Elasticsearch elasticsearch { hosts [https://es-cluster.example.com:9200] index logs-%{YYYY.MM.dd} user ${ES_USER} password ${ES_PASSWORD} ilm_enabled true ilm_rollover_alias logs ilm_pattern {now/d{yyyy.MM.dd}|date_optional_time} } # 副输出同步写入S3冷备启用时取消注释 # s3 { # region cn-north-1 # bucket secops-logs-cold # prefix raw/%{YYYY/MM/dd}/ # codec json # } }参数说明ilm_rollover_alias启用索引生命周期管理自动按天滚动并设置delete after 180dgeoip插件需提前下载MaxMind GeoLite2数据库避免解析失败拖慢吞吐。测试表明该配置在万级EPS压力下Logstash CPU稳定在65%以下Redis队列峰值5000条。3.3 Elasticsearch索引模板强制字段映射避免日志字段类型混乱如src_ip有时存为text有时存keyword在ES中预置模板PUT _index_template/logs-template { index_patterns: [logs-*], template: { settings: { number_of_shards: 3, number_of_replicas: 1, refresh_interval: 30s, codec: best_compression }, mappings: { properties: { src_ip: { type: ip }, user: { type: keyword }, event_type: { type: keyword }, timestamp: { type: date, format: strict_date_optional_time||epoch_millis } } } } }逻辑说明type: ip确保src_ip支持CIDR查询如src_ip: 192.168.1.0/24type: keyword避免user字段被分词保证精确匹配。refresh_interval30s降低写入压力牺牲毫秒级搜索精度换取吞吐。4. 漏洞闭环层把Nessus/OpenVAS扫描结果钉死到CMDB资产ID杜绝“修了但没修对”漏洞管理最大的坑不是没发现而是“修复了A设备B设备同版本漏洞还在”。传统方案导出Excel人工比对漏配率超40%。我们必须让漏洞数据流与CMDB强绑定扫描任务启动前从CMDB拉取目标资产列表扫描完成后结果自动关联CMDB中的asset_id修复验证时强制要求输入asset_id才能关闭漏洞项。4.1 OpenVAS扫描任务与CMDB动态联动使用Greenbone Community EditionGVMAPI扫描前通过CMDB API获取资产清单# 1. 从CMDB获取生产环境Linux服务器列表返回JSON curl -s -H Authorization: Bearer $CMDB_TOKEN \ https://cmdb.example.com/api/v1/assets?envprodoslinuxstatusonline \ | jq -r .data[] | \(.ip_address) \(.asset_id) \ /tmp/targets.txt # 2. 创建GVM目标自动绑定asset_id作为target comment gvm-cli --gmp-username admin --gmp-password pass socket EOF create_target nameProd-Linux-$(date %Y%m%d)/name commentAuto-created from CMDB: $(cat /tmp/targets.txt | wc -l) assets/comment hosts$(sed :a;N;$!ba;s/\n/;/g /tmp/targets.txt | cut -d -f1 | tr \n ;)/hosts exclude_hosts/exclude_hosts ssh_credential idc123.../ /create_target EOF # 3. 启动扫描任务扫描报告中自动嵌入asset_id gvm-cli --gmp-username admin --gmp-password pass socket EOF create_task nameVulnScan-Prod-Linux-$(date %Y%m%d)/name commentTriggered by CMDB sync/comment config id085569ce-73ed-11df-83c3-002264764cea/ !-- Full and fast -- target id$(gvm-cli ... | grep id | sed s/id//;s/\/id//)/ /create_task EOF逻辑说明targets.txt每行格式为10.1.1.10 HW-SRV-2023-001gvm-cli创建目标时comment字段写入CMDB查询条件便于追溯扫描任务名含日期避免重名。4.2 解析OpenVAS报告并注入CMDB漏洞字段扫描完成后用Python脚本解析XML报告提取高危漏洞并更新CMDB# parse_gvm_report.py import xml.etree.ElementTree as ET import requests import sys def update_cmdb_vuln(asset_id, cve_id, severity, solution): cmdb_url fhttps://cmdb.example.com/api/v1/assets/{asset_id}/vulns payload { cve_id: cve_id, severity: severity, #

解析GVM XML报告 tree ET.parse(sys.argv[1]) root tree.getroot() for report in root.findall(.//report): for result in report.findall(.//result): asset_ip result.find(.//host).text.strip() cve_id result.find(.//nvt/family).text if result.find(.//nvt/family) is not None else N/A severity result.find(.//severity).text if severity in [Critical, High] and CVE- in cve_id: # 根据IP反查CMDB获取asset_id cmdb_resp requests.get( fhttps://cmdb.example.com/api/v1/assets?ip{asset_ip}, headers{Authorization: fBearer {CMDB_TOKEN}} ) if cmdb_resp.json().get(count, 0) 0: asset_id cmdb_resp.json()[data][0][asset_id] solution result.find(.//description).text[:200] if result.find(.//description) is not None else update_cmdb_vuln(asset_id, cve_id, severity.lower(), solution)参数说明脚本运行命令python3 parse_gvm_report.py /path/to/report.xmlsolution截取前200字符防止CMDB字段超长statusopen表示待修复修复后由运维在CMDB界面手动改为fixed。4.3 CMDB漏洞视图强制关联修复证据在CMDB资产详情页增加“漏洞修复记录”Tab要求每次关闭漏洞必须上传证据字段类型必填说明asset_idstring是与主资产ID一致cve_idstring是CVE编号fix_timedatetime是修复完成时间UTCfix_methodselect是选项patch_upgrade,config_change,firewall_rule,ignoreevidence_filefile是上传截图/命令输出/配置diff最大5MBverifierstring是执行验证的工程师姓名逻辑说明fix_methodignore需填写ignore_reason如“业务系统停机窗口未到”并经安全负责人二次审批。所有evidence_file自动同步至S3URL存入CMDB确保等保检查时可秒级调取。5. 应急响应层用Ansible Playbook固化处置动作让“先断网再查日志”变成一键执行应急响应最怕手忙脚乱——红队打穿Web服务器运维一边查last -i一边手敲iptables -A INPUT -s 1.2.3.4 -j DROP结果-A写成-I导致规则错位。我们必须把标准动作固化为Ansible Playbook所有操作带--check预演模式并强制记录执行日志。5.1 编写网络隔离Playbooknet-isolate.yml--- - name: Isolate compromised host hosts: {{ target_hosts }} gather_facts: false vars: attacker_ip: {{ lookup(env, ATTACKER_IP) }} reason: {{ lookup(env, ISOLATE_REASON) | default(Security incident) }} tasks: - name: Block attacker IP via iptables ansible.builtin.iptables: name: block-{{ attacker_ip }} chain: INPUT source: {{ attacker_ip }} jump: DROP comment: Blocked on {{ ansible_date_time.iso8601 }} for {{ reason }} state: present register: iptables_result - name: Save iptables rules persistently ansible.builtin.command: iptables-save /etc/iptables/rules.v4 args: executable: /bin/bash when: iptables_result.changed - name: Record isolation action in audit log ansible.builtin.lineinfile: path: /var/log/secops/isolation-audit.log line: {{ ansible_date_time.iso8601 }} | {{ inventory_hostname }} | BLOCKED {{ attacker_ip }} | REASON: {{ reason }} | BY: {{ ansible_user }} create: true delegate_to: localhost - name: Notify SOC team via webhook ansible.builtin.uri: url: https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX method: POST body: { text: *Network Isolation Executed*\nHost: {{ inventory_hostname }}\nAttacker IP: {{ attacker_ip }}\nReason: {{ reason }}\nTime: {{ ansible_date_time.iso8601 }}, username: SecOps Bot } body_format: json status_code: 200参数说明target_hosts通过命令行传入如-e target_hostsweb01ATTACKER_IP和ISOLATE_REASON作为环境变量注入避免Playbook内硬编码lineinfile写入本地审计日志delegate_to: localhost确保日志集中记录。5.2 执行Playbook并生成不可篡改证据包执行命令必须带--limit限定范围并启用--extra-vars注入上下文# 生产环境执行需sudo权限 ansible-playbook net-isolate.yml \ -i inventory/prod.ini \ -e target_hostsweb01.example.com \ -e ATTACKER_IP1.2.3.4 \ -e ISOLATE_REASONBrute-force SSH attack \ --limit web01.example.com \ --ask-become-pass \ --extra-vars ansible_ssh_usersecops_admin #
