JNCIA-SEC and JNCIS-SEC lab 2 of 16

Security policies with objects and order

Replace an empty rule base with named addresses and applications, get the order right, find a shadowed rule, add a global policy, and see why unified policies need a signature package.

Run this lab

It needs Lite: its 4 nodes are set to 5 vCPU and 7,168 MB in total. That fits the free demo too.

In your workspace: Shared, then JNCIA-SEC and JNCIS-SEC SRX security guided labs, then 02 - Security policies with objects and order

The scenario

Hartwell's auditors have looked at the Poole firewall and asked for a rule base they can read: named objects, the right order, and a log of what gets refused. The interfaces and zones are done. There are no policies yet, so nothing crosses a zone boundary. LAN-PC holds three addresses on one desktop, so you can test as three people.

DeviceInterfaceAddressZone or gateway
SRXge-0/0/0203.0.113.1/24zone untrust
SRXge-0/0/110.10.10.1/24zone trust

Admin (Ana)10.10.10.50web, and the admin console on TCP 8080
Contractor (Cal)10.10.10.60nothing at all

DMZ-WEB runs the public site on port 80 and an admin console on port 8080. OUT plays a software patch server at 203.0.113.10.

To test as someone else, use curl --interface:

curl -m 8 --interface 10.10.10.50 http://10.10.20.10:8080/

What you’ll practise

  • Build address books, address-sets, custom applications and application-sets
  • Order policies so the first match is the right one
  • Use shadow-policies and match-policies to prove behaviour
  • Compare deny and reject
  • Use a global policy for a rule that applies everywhere

The tasks

  1. Address book
  2. Applications
  3. Policies from trust to dmz
  4. Order and shadowing
  5. A global policy
  6. Unified policies (reading only)

The Lab Tasks pane has the scenario, these tasks, the checks to run, hints and the full solution.

Topology and devices

The network as it opens in EVE-NG, drawn from the lab’s own canvas, and the image each node runs.

How to open this lab

  1. Sign in to your workspace at lab.cloudlabbox.com.

  2. In File Manager, open Shared, then the folder JNCIA-SEC and JNCIS-SEC SRX security guided labs.

  3. Open 02 - Security policies with objects and order and start its nodes, then open Lab Tasks for the scenario and the steps.

The lab is read-only. You can start the nodes and configure the devices, but changes to the topology can’t be saved. To change it, rebuild it in your own folder.
