Cisco ESA C190 — конфигурация SSL

Cisco Email Security Appliance

Настроить конфигурацию SSL/TLS методов и SSL ciphers можно через GUI или по SSH.

По SSH

В CLI вы можете использовать команду:

sslconfig

Настройки по умолчанию выглядят так:

esa.servername.local> sslconfig

sslconfig settings:
  GUI HTTPS method:  tlsv1_0tlsv1_1tlsv1_2
  GUI HTTPS ciphers:
        RC4-SHA
        RC4-MD5
        ALL
        -aNULL
        -EXPORT
  Inbound SMTP method:  tlsv1_0tlsv1_1tlsv1_2
  Inbound SMTP ciphers:
        RC4-SHA
        RC4-MD5
        ALL
        -aNULL
        -EXPORT
  Outbound SMTP method:  tlsv1_0tlsv1_1tlsv1_2
  Outbound SMTP ciphers:
        RC4-SHA
        RC4-MD5
        ALL
        -aNULL
        -EXPORT

Choose the operation you want to perform:
- GUI - Edit GUI HTTPS ssl settings.
- INBOUND - Edit Inbound SMTP ssl settings.
- OUTBOUND - Edit Outbound SMTP ssl settings.
- VERIFY - Verify and show ssl cipher list.
[]>

Далее можно использовать команды:

  • gui —- конфигурация web-интерфейса
  • inbound — конфигурация входящего SMTP трафика
  • outbound — конфигурация исходящего SMTP трафика
  • veryfy проверка cipher list
[]> inbound

Enter the inbound SMTP ssl method you want to use.
1. TLS v1.0
2. TLS v1.1
3. TLS v1.2
4. SSL v2
5. SSL v3
[2, 3]> 2, 3

Enter the inbound SMTP ssl cipher you want to use.
[MEDIUM:HIGH:-SSLv2:-aNULL:!RC4:@STRENGTH:-EXPORT]>
[]> verify

Enter the ssl cipher you want to verify.
[]> RC4-SHA:RC4-MD5:ALL:-aNULL:-EXPORT
