Note: Appropriate verification procedures should be taken after each configuration task to ensure that it has been properly implemented.

Step 1: Configure Basic Device Hardening for the CORP and the Internal Routers.

  1. Configure the CORP and the Internal routers to only accept passwords with a minimum length of 10 characters.
  2. Configure an encrypted privileged level password of ciscoclass.
  3. Enable password encryption for all clear text passwords in the configuration file.
  4. Configure the console port and all vty lines with the following requirements:Note: Both the CORP and the Internal routers are already configured with the username CORPADMIN and password Ciscoccnas.
    • Use the local database for login.
    • Disconnect after being idle for 20 minutes.
  5. Disable the CDP protocol on the CORP router on the link to the Internet router.

Step 2: Configure Secure Network Management for the CORP Router.

  1. Configure the IOS login enhancement for all vty lines with the following requirements:
  • Disable logins for 30 seconds after 3 failed login attempts within 60 seconds.

Step 3: Configure Secure Network Management for the Internal Router.

  1. Configure the Internal router:
    • as an NTP client to the AAA/NTP/Syslog server
    • to update the router calendar (hardware clock) from the NTP time source
    • to timestamp log messages
    • to send logging messages to the AAA/NTP/Syslog server
  2. Configure the IOS login enhancement for all vty lines with the following requirements:
    • Disable logins for 30 seconds after 3 failed login attempts within 60 seconds.
    • Log any failed or successful login to the syslog server.
  3. Configure the Internal router to accept SSH connections. Use the following guidelines:Note: Internal is already configured with the username SSHAccess and the secret password ciscosshaccess.
    • The domain name is theccnas.com.
    • RSA encryption key pair using a modulus of 1024
    • SSH version 2, timeout of 90 seconds, and 2 authentication retries
    • All vty lines accept only SSH connections.
  4. Configure the Internal router with server-based AAA authentication and verify its functionality:Note: The AAA server is already configured with RADIUS service, a username CORPSYS, and the password LetSysIn.
    • The key to connect to the RADIUS server is corpradius.
    • AAA authentication uses the RADIUS server as the default for console line and vty lines access.
    • The local database is used as the backup if the RADIUS server connection cannot be established.

Step 4: Configure ACLs on the Internal Router to Implement Secure Management Access.

  1. Create ACL 12 to implement the security policy regarding the access to the vty lines:
  • Only users logged on to the Net Admin PC are allowed access to the vty lines.

 Step 5: Configure Device Hardening for Switch1 and Switch4

  1. Access Switch1 and Switch4 with username CORPADMIN, password Ciscoccnas, and the enable secret password of ciscoclass.
  2. Configure Switch1 to protect against STP attacks.
    • Configure PortFast on FastEthernet ports 0/1 to 0/22.
    • Enable BPDU guard on FastEthernet ports 0/1 to 0/22.
  3. Configure Switch1 port security and disable unused ports.
    • Set the maximum number of learned MAC addresses to 2 on FastEthernet ports 0/1 to 0/22. Allow the MAC address to be learned dynamically and to be retained in the running-config. Shutdown the port if a violation occurs.
    • Disable unused ports (Fa0/2-4, Fa0/6-10, Fa0/13-22).
  4. Configure the trunk link on Fa0/23 and Fa0/24 on both Switch1 and Switch4
    • Disable DTP negotiation on the trunking ports.
    • Set the native VLAN as VLAN 50 for the trunk links.

Step 6: Configure an IOS IPS on the Internal Router.

  1. On the Internal router, if asked to login, then login as CORPSYS with password LetSysIn. The enable secret password is ciscoclass.
  2. Use the IPS signature storage location at flash:.
  3. Create an IPS rule named corpips.
  4. Configure the IOS IPS to use the signature categories. Retire the all signature category and unretire the ios_ips basic category.
  5. Apply the IPS rule to the Gi0/0 interface in the out direction.
  6. Modify the ios_ips basic category. Unretire the echo request signature (signature 2004, subsig 0); enable the signature; modify the signature event-action to produce an alert and deny packets that match the signature.
  7. Verify that IPS is working properly. Net Admin in the internal network cannot ping DMZ Web Svr. DMZ Web Svr, however, can ping Net Admin.

Step 7: Configure ZPF on the CORP Router.

  1. Access the CORP router with username CORPADMIN, password Ciscoccnas, and the enable secret password of ciscoclass.
  2. Create the firewall zones.
    • Create an internal zone named CORP-INSIDE.
    • Create an external zone named INTERNET.
  3. Define a traffic class to allow traffic from the Internal network to access services in the Internet.
    • Create a class map using the option of class map type inspect with the match-any keyword. Name the class map INSIDE_PROTOCOLS.
    • Match the protocols, httptcpudpicmpdns (Please note, the order of match statements is significant only because of the scoring need in Packet Tracer.)
  4. Specify firewall policies to allow internal hosts to access Internet.
    • Create a policy map named INSIDE_TO_INTERNET.
    • Use the INSIDE_PROTOCOLS class map.
    • Specify the action of inspect for this policy map.
  5. Define a traffic class to allow traffic from the Internet to access services in the DMZ network.
    • Create a class map using the option of class map type inspect with the match-any keyword. Name the class map DMZ_WEB.
    • Match the protocols, http and dns (Please note, the order of match statements is significant only because of the scoring need in Packet Tracer.)
  6. Specify firewall policy to allow Internet traffic to access DMZ services.
    • Create a policy map named INTERNET_TO_DMZWEB.
    • Use the DMZ_WEB class map.
    • Specify the action of pass for this policy map.
  7. Apply the firewall.
    • Create a pair of zones named IN_TO_OUT_ZONE with the source as CORP-INSIDE and destination as INTERNET.
    • Specify the policy map INSIDE_TO_INTERNET for handling the traffic between the two zones.
    • Create a pair of zones named INTERNET_TO_DMZ_ZONE with the source as INTERNET and destination as CORP-INSIDE.
    • Assign interfaces to the appropriate security zones.
  8. Verify the ZPF configuration.
    • The External user can access the URLs http://www.theccnas.com and http://www.externalone.com.
    • The External user cannot ping the DMZ Web Svr.
    • The PCs in the internal network can ping and access the External Web Svr URL.

  1. The ACL 12 and then activating it is not so difficult (100% sure – confirmed)

    access-list 12 permit host 172.16.25.5
    line vty 0 15
    access-class 12 in
    exit

    Also you have to configure login local before you activate aaa (pretty sure)

    line vty 0 15
    login local
    line con 0
    login local
    exit

  2. For Internal Config is continuing with:
    interface Gi0/0
    ip ips corpips out
    exit
    (config)#ip ips signature-definition
    (config-sigdef)# signature 2004 0
    (config-sigdef-sig)# status
    (config-sigdef-sig-status)# retired false
    (config-sigdef-sig-status)# enable true
    (config-sigdef-sig-status)# exit
    (config-sigdef-sig)# engine
    (config-sigdef-sig-engine)# event-action produce-alert
    (config-sigdef-sig-engine)# event-action deny-packet-inline
    (config-sigdef-sig-engine)# exit
    (config-sigdef-sig)# exit
    (config-sigdef)# exit
    (config)# exit

    My score was 90.0 % . Thanks invialgo.com for all.

  3. Thanks for all the notes and comments. I got a 100% using the commands provided, using STEAM, and DAFRELUF notes.

  4. If you want to score a 100%, you must put one single line authentication aaa (first line) :

    aaa authentication login default group radius local –> good

    aaa authentication login default local ————> bad, because if you put both lines you delete the first line, that is the correct option.

    100% proved 😉

      1. Just asking as not sure, will this be the fianal graded exam we get? or is this only a practise exam in which the marks dont count towards anything?

    1. Can you please type the entire Radius config?

      209.165.200.252 is not a host address, it is the /30 network between CORP and INTERNAL.
      On the radius host command we need to specify the AAA Radius server address which seems to be 172.16.25.2, right?

  5. Thank you guy very much, this has saved my life! I literally forgot alot of the commands and it would take me forever to find them, which would have definitely lowered my score.

  6. I follow the configuration posted but I constantly get a 92% due to the following:

    1. *radius server line on Internal seems incorrect
    Do we really need to config the “authentication” line?
    What else might be wrong?
    2. *Switch 4 does not accept the “switchport nonegotiate” line (all is ok with Switch 1)
    It returns an error: Command rejected: Conflict between ‘nonegotiate’ and ‘dynamic’ status.

    Any ideas folks?

    1. Becouse the port is in dynamic or trunking mode and cannot allow no negociate mode

      first you need change the ports to mode accesss and later use mode no negociate and you router will accept the comand

    2. Radius server has the address 172.16.25.2 (AAA/NTP/Syslog Svr).
      Before the command “switchport nonegotiate” must introduce the command “switchport mode access”.

  7. I made the changes and got 95%.

    I removed this line,

    aaa authentication login default local

    and I added other lines below.

    I got this:

    AAA Authentication 0 5
    Network:Internal:Console Line:AAA Method List Name Correct
    Network:Internal:VTY Lines:0:AAA Method List Name Correct
    Network:Internal:AAA:Authentication:1 Correct
    Network:Internal:AAA:New-model Correct
    Network:Internal:RADIUS Client:RADIUS Server Hosts:0 Incorrect

  8. This one works. I got 100%

  9. I followed Alexander’s work, got 75/100. In the feedback, everything was fully complete with the exception of Configuring Basic Router Security and Configuring ZBF being only partially complete. Under Line Timeout it says:

    Network:CORP:Console Line:Exec-timeout Correct
    Network:CORP:VTY Lines:0:Exec-timeout Correct
    Network:Internal:Console Line:Exec-timeout Correct
    Network:Internal:VTY Lines:0:Exec-timeout Incorrect

  10. Hi,
    Did the CCNAs cert in july (didn’t pass) and there were no simulations what so ever, is that part removed or was it just my luck?

  11. Hello Guys,

    I think you don’t have to put those line :

    line vty 0 4
    login authentication default
    line vty 5 15
    login authentication default
    line con 0
    login authentication default

    Because the command :
    aaa authentication login default group radius local
    is already apply everywhere by default ( I did the test in my lab).

    You also don’t have to put this command :
    aaa authorization exec default local
    Because nowhere it is mentioned that you have to configure authorization, just authentication is needed.
    Also you can go faster for the switch command with :

    int range fa0/2 – 4, fa0/6 – 10 , fa0/13 – 22

    a+

  12. CORP(config-if)#zone security CORP-INSIDE
    ^
    % Invalid input detected at ‘^’ marker.

    This command is not working guys. Can anyone point out the mistake? Using a windows system.

  13. I’ve taken the test yesterday – I got 95 % but I assume that’s due to my try to do it on my own. Anyways, I just wanted to say the test is viable and anyone that is going to take that test can use it! Thank You guys, You are awesome!
