AAA (Authentication, Authorization and Accounting) Huawei

Ağ güvenliği tanımlamasında kimlik doğrulama, yetkilendirme ve muhasebe terimlerinin ilklerini tanımlayan ve ağdan gelen bilgi paketlerini bazı modellere göre dikkatlice inceleyen ve kötü niyetli faaliyetleri bilgilendiren bir sistemdir.
Authentication: sunucu, anahtar veya yönlendirici kullanırken cihazın veya kullanıcının doğrulanması.
Authorization: Kullanıcıya veya kullanıcılara sisteme, programa ve ağa erişim izni verme.
Accounting: herhangi bir kullanıcı ne yapar, kullanıcı işlemleri, kullanıcı veri bağlantıları ve kullanıcı sistem kayıtları

  1. Cihaz isimleri ve ip address verme.
    [Huawei]sysname Router11111
    [Router1]interface GigabitEthernet 0/0/0
    [Router1-GigabitEthernet0/0/0]ip address 119.84.111.1 24
    [Huawei]sysname Router3
    [Router3]interface GigabitEthernet 0/0/0
    [Router3-GigabitEthernet0/0/0]ip address 119.84.111.3 24
    Router1 ve Router3 arasındaki bağlantıyı kontrol edelim.

  2. Router1 cihazı için AAA konfigürasyonunu yapılandırma.
    Router1 routeri için authentication-schame ve authorization-schame konfigurasyonlarını tamamlayalım ve aynı ayarları Router3 içinde yapalım.
    [Router1]aaa
    [Router1-aaa]authentication-scheme auth1
    Info: Create a new authentication scheme.
    [Router1-aaa-authen-auth1]authentication-mode local
    [Router1-aaa-authen-auth1]quit
    [Router1-aaa]authorization-scheme auth2
    Info: Create a new authorization scheme.
    [Router1-aaa-author-auth2]authorization-mode local
    [Router1-aaa-author-auth2]quit
    Router1’in domaini huawei olarak yapılandıralım, daha sonra oluşturduğumuz kullanıcılarda buna uygun olarak yapılandıralım.
    [Router1-aaa]domain huawei
    Info: Success to create a new domain.
    [Router1-aaa-domain-huawei]authentication-scheme auth1
    [Router1-aaa-domain-huawei]authorization-scheme auth2
    [Router1-aaa-domain-huawei]quit
    [Router1-aaa]local-user user1@huawei password cipher huawei
    Info: Add a new user.
    [Router1-aaa]local-user user1@huawei service-type telnet
    [Router1-aaa]local-user user1@huawei privilege level 0
    Router1 cihazında AAA authentication modda telnet serverı etkinleştirelim.
    [Router1]user-interface vty 0 4
    [Router1-ui-vty0-4]authentication-mode aaa
    Router1 cihazında telnet hizmetinin başarıyla kurulup kurulmadığını kontrol edelim.
    telnet 119.84.111.1
    Trying 119.84.111.1 …
    Press CTRL+K to abort

    quit
  3. Router3 cihazı için AAA konfigürasyonunu yapılandırma.
    [Router3]aaa
    [Router3-aaa]authentication-scheme auth1
    Info: Create a new authentication scheme.
    [Router3-aaa-authen-auth1]authentication-mode local
    [Router3-aaa-authen-auth1]quit
    [Router3-aaa]authorization-scheme auth2
    Info: Create a new authorization scheme.
    [Router3-aaa-author-auth2]authorization-mode local
    [Router3-aaa-author-auth2]quit
    Router3’in domaini huawei olarak yapılandıralım, daha önce oluşturduğumuz kullanıcılara uygun olsun.
    [Router3-aaa]domain huawei
    [Router3-aaa-domain-huawei]authentication-scheme auth1
    [Router3-aaa-domain-huawei]authorization-scheme auth2
    [Router3-aaa-domain-huawei]quit
    [Router3-aaa]local-user user3@huawei password cipher huawei
    Info: Add a new user.
    [Router3-aaa]local-user user3@huawei service-type telnet
    [Router3-aaa]local-user user3@huawei privilege level 0
    Router1 cihazında AAA authentication modda telnet serverı etkinleştirelim.
    [Router3]user-interface vty 0 4
    [Router3-ui-vty0-4]authentication-mode aaa
    Router3 cihazında telnet hizmetinin başarıyla kurulup kurulmadığını kontrol edelim.
    telnet 119.84.111.3
    Trying 119.84.111.3 …
    Press CTRL+K to abort
    Connected to 119.84.111.3 …
    Login authentication
    Username:user3@huawei
    Password:
