Step 6 Configure SSH

In some circumstances, attackers may be able to use a packet analyzer to intercept telnet passwords, which may enable them to gain access to the AP or other networking devices. The SSH protocol is a secure form of telnet, providing both authentication and encryption.

First, begin by generating the asymmetric keys used in the SSH authentication process.

Generate RSA keys

a. Enter the following command in the configuration mode:

b. What are the available help options for this command?

general-keys Generate a general purpose RSA key pair for signing and

encryption usage-keys Generate seperate RSA key pairs for signing and

encryption

Generate RSA keys (continued)

• To enable SSH for local and remote authentication on the AP, enter the command crypto key generate rsa and press Enter. The AP will respond with a message showing the naming convention for the keys.

c. What is the default size, in bits, of the key modulus?

d. Press Enter to accept the default key size and continue.

Step 7 Configure SSH timeouts

a. Configuring SSH timeouts and authentication retries is a way of providing additional security for the connection. Use the command ip ssh {[time-out seconds]}

{authentication-retries integer} to enable timeouts and authentication retries.

Set the SSH timeout to 15 seconds and the amount of retries to 3 by entering the following commands:

1. What is the maximum timeout value allowed? What is the maximum amount of authentication retries allowed?

Step 8 Configure local authentication and VTY

a. Use the following commands to define a local user and assign SSH communication to the vty lines:

1. What are the available parameters for the transport input command?

    步驟6-SSH成形

    某些情況下,駭客能使用一種分析器攔截遠程登錄密碼,這可以使他們能夠進入美聯社或者其他聯網設備。SSH協議是一個遠程登錄的安全形式,提供驗証和加密。

    首先,請先產生在SSH驗証過程裡必須用到的隨機註冊金鑰。

    產生RSA註冊金鑰

    a.在下述模式下輸入以下命令︰

    b.此命令的有效幫助之選項為何?

    一般的註冊金鑰產生一個多功能的RSA關鍵與

    加密用註冊金鑰產生Seperate RSA關鍵和加密

    產生RSA註冊金鑰(繼續)

    為使本地或遠端在美聯社驗証成功,及使SSH高級會員金鑰產生RSA,請輸入RSA的命令密碼並按Enter鍵。美聯社將回覆一串訊息顯示註冊金鑰的排列序號。

    c.註冊金鑰的標準數值之預設檔案大小為多少?

    d.按Enter鍵來認可預設註冊金鑰的檔案大小並繼續。

    步驟7-SSH瀏覽程式成形

    a.使SSH瀏覽程式和反覆驗證成形的其一辦法是在連線時添加防護。使用命令IP SSH {[逾時秒數]}

    {反覆驗證整數}使瀏覽程式逾時和反覆驗證。

    透過輸入下列命令將SSH瀏覽程式設定成15秒並將重試次數設為3:

    1.允許的逾時數值之最大值為何?允許的重試次數之最大值為何?

    步驟8-使本地驗証和VTY成形

    a.使用下列命令確定一個本地用戶,並將SSH通訊添加到VTY列︰

    1.傳輸用的有效參數命令為何?

    Cisco的認證相當好用,如果你要走網路管理的話,那這一張認證將是求職必備的加分利器!!

    但是你的英文似乎不是很好耶@@建議你將英文學好,以後各種國際認證都不必怕看不懂了
