高级SSL检测技巧

1. 自定义密码套件检测

id: custom-cipher-check
info:
  name: Custom Cipher Suite Check
  author: security-team
  severity: medium
  tags: ssl,cipher,custom

ssl:
  - address: "{{Host}}:{{Port}}"
    cipher_suites:
      - "TLS_RSA_WITH_RC4_128_MD5"
      - "TLS_RSA_WITH_RC4_128_SHA"
      - "TLS_ECDHE_RSA_WITH_RC4_128_SHA"
    min_version: "tls10"
    max_version: "tls12"

    matchers:
      - type: dsl
        dsl:
          - 'probe_status == true'
          - 'cipher != ""'

2. TLS版本限制检测

id: tls-version-restriction
info:
  name: TLS Version Restriction Test
  author: security-team
  severity: info
  tags: ssl,tls,version

ssl:
  - address: "{{Host}}:{{Port}}"
    min_version: "tls13"
    max_version: "tls13"

    matchers:
      - type: dsl
        name: tls13-only-supported
        dsl:
          - 'probe_status == true'
          - 'tls_version == "tls13"'

  - address: "{{Host}}:{{Port}}"
    min_version: "tls12"
    max_version: "tls12"

    matchers:
      - type: dsl
        name: tls12-supported
        dsl:
          - 'probe_status == true'
          - 'tls_version == "tls12"'

  - address: "{{Host}}:{{Port}}"
    min_version: "tls10"
    max_version: "tls11"

    matchers:
      - type: dsl
        name: legacy-tls-supported
        dsl:
          - 'probe_status == true'
          - 'contains(tls_version, "tls1")'

SSL/TLS安全加固最佳实践

1. 证书管理最佳实践

mermaid

2. 加密配置加固指南

安全配置项推荐设置风险说明
TLS版本TLS 1.2+TLS 1.0/1.1存在已知漏洞
密码套件前向安全算法避免使用静态RSA密钥交换
密钥长度2048位以上1024位密钥安全性较低
证书有效期90天以内缩短有效期减少风险暴露

3. 自动化监控方案

          - 'probe_status == true && self_signed == true'
          - 'probe_status == true && contains(tls_version, "sslv3")'

      - type: dsl
        name: high-issues
        severity: high
        dsl:
          - 'probe_status == true && not_after < now().AddDate(0, 0, 30)'
          - 'probe_status == true && contains(tls_version, "tls10")'

      - type: dsl
        name: medium-issues
        severity: medium
        dsl:
          - 'probe_status == true && not_after < now().AddDate(0, 1, 0)'
          - 'probe_status == true && !contains(tolower(string(domains)), tolower(hostname))'
