Test Encrypted Patch

Description

Configures three DUTs, encrypts a patch that allows SSH communication between the DUTs and enables bypass. The original input file was:

drop ssh any any -> any any (msg: "SSH not allowed in this network"; sid: 2;)
pass icmp any any -> any any (msg: "ICMP traffic ignored"; sid: 3;)

After applying the following patch:

1c1
< drop ssh any any -> any any (msg: "SSH not allowed in this network"; sid: 2;)
---
> alert ssh any any -> any any (msg: "SSH traffic detected - bypassing"; bypass; sid: 2;)

The resulting file must be:

alert ssh any any -> any any (msg: "SSH traffic detected - bypassing"; bypass; sid: 2;)
pass icmp any any -> any any (msg: "ICMP traffic ignored"; sid: 3;)

This not only allows SSH traffic but also enables the bypass feature (not tested here yet).

Test Compressed Ruleset With Patch

Description

Configures three DUTs, places a patch between the DUTs that allows SSH communication, and enables bypass. In addition, there are two source rules that are compressed into a tar.gz file whose content is used by the firewall to define the rules. One of the files is named base.rules``and is the file that the patch is meant for. The second one is ``test-performance.rules whose contents are:: The original input file was:

alert tcp any any -> any 5001 (msg: "Skipping test network performance traffic"; bypass; flow: established, to_server; sid: 4;)

This rule simply bypasses traffic that is deemed “performance traffic”, which is directly associated with the monitor test performance command.

Test Capture Bypass

Description

Builds a scenario with three DUTs in which a performance test is conducted between DUT1 and DUT2, and DUT0 is the router running the firewall. “Capture bypass” is set to allow the firewall to mark packets. An external tool can then decide what to do with the flow when the mark is seen. For this example, when packet marks are detected, the traffic is assigned a label, thereby allowing the possibility of classifying traffic. In particular, labeling avoids traffic from entering the firewall.

Performance must improve considerably compared to the previous test.

Test Simple Capture Bypass

Description

Builds a scenario with three DUTs in which a performance test is conducted between DUT1 and DUT2, and DUT0 is the router running the firewall. This test sets the conntrack mark directly, thus skipping all the steps required to set it later.

Performance must improve considerably compared to the previous test.

Scenario

Step 1: Run command file copy http://10.215.168.1/~robot/test-performance.rules running:// force at DUT0 and expect this output:

Show output
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   129  100   129    0     0   8062      0 --:--:-- --:--:-- --:--:--  8062

Step 2: Set the following configuration in DUT0:

set service firewall FW ruleset file running://test-performance.rules
set service firewall FW mode inline queue FW_Q
set service firewall FW logging outputs fast
set service firewall FW logging level config
set service firewall FW validator-timeout 20
set interfaces ethernet eth0 traffic policy in FW_PWAN
set interfaces ethernet eth0 traffic policy out FW_PWAN
set interfaces ethernet eth1 vif 101 traffic policy in FW_PLAN
set interfaces ethernet eth1 vif 201 traffic policy in FW_PLAN
set traffic queue FW_Q elements 1
set traffic policy FW_PWAN
set traffic policy FW_PLAN
set traffic selector FW_SEL
set service firewall FW stream bypass mark 129834765
set service firewall FW stream bypass mask 129834765
set service firewall FW stream bypass set-connmark
set traffic selector FW_SEL rule 1 not connmark 129834765
set traffic policy FW_PLAN rule 1 selector FW_SEL
set traffic policy FW_PWAN rule 1 selector FW_SEL
set traffic policy FW_PLAN rule 1 action enqueue FW_Q
set traffic policy FW_PWAN rule 1 action enqueue FW_Q

Step 3: Ping IP address 20.0.0.2 from DUT1:

admin@DUT1$ ping 20.0.0.2 count 1 size 56 timeout 1
Show output
PING 20.0.0.2 (20.0.0.2) 56(84) bytes of data.

--- 20.0.0.2 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.687/0.687/0.687/0.000 ms

Step 4: Ping IP address 40.0.0.2 from DUT2:

admin@DUT2$ ping 40.0.0.2 count 1 size 56 timeout 1
Show output
PING 40.0.0.2 (40.0.0.2) 56(84) bytes of data.
64 bytes from 40.0.0.2: icmp_seq=1 ttl=63 time=0.603 ms

--- 40.0.0.2 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.603/0.603/0.603/0.000 ms

Step 5: Initiate a bandwidth test from DUT2 to DUT1

admin@DUT1$ monitor test performance server port 5001
admin@DUT2$ monitor test performance client 40.0.0.2 duration 10 port 5001
Expect this output in DUT2:

Step 6: Run command service firewall FW show logging fast | tail at DUT0 and check if output matches the following regular expressions:

(?m)^.+(Skipping test network performance traffic).+$
Show output

Test Selectors

Description

Builds a scenario with three DUTs in which some selectors are applied to traffic depending on the network detected. This allows specific selector-based rules to be applied to traffic and with only one firewall instance.

To demonstrate this behavior, two labels will be set:

  1. WAN label that is applied to every packet going outside the local network.

  2. LAN label that marks every packet present in the underlying network.

For this purpose, a whole scenario will be used to enable all the features to work:

  • A compressed, encrypted ruleset will be created that contains base.rules as well as test-performance.rules.

  • A patch that will upgrade base.rules so it contains rules based on labels. The expected final result will be:

    alert ssh any any -> any any (msg: "Local SSH traffic - bypassing..."; selector: LOCAL; bypass; sid: 1; flow: established, to_server;)
    drop ip any any -> any any (msg:"GPL ATTACK_RESPONSE id check returned root"; content:"uid=0|28|root|29|"; classtype:bad-unknown; sid:2100498; rev:7; metadata:created_at 2010_09_23, updated_at 2010_09_23; selector: WAN;)
    pass icmp any any -> any any (msg: "ICMP traffic ignored"; sid: 3;)
    drop tcp any any -> any 5000 (msg: "Dropping TCP performance test traffic"; selector: WAN, LOCAL; sid: 4; flow: established, to_server;)
    

Hence, the following will be tested:

  1. SSH connection is working between the LAN nodes - DUT1 and DUT2

  2. It is impossible to get the nids.html file (i.e., a malicious file) from the WAN.

  3. ICMP messages are allowed from any node within the network.

  4. Traffic performance tests are allowed for both the WAN and LOCAL selectors but not on port 5000.

Test XDP Filtering

Description

Builds a scenario with three DUTs and a simple ruleset to drop TCP traffic between DUT1 and DUT2. Such traffic must pass through port 5000 for the rule to match. Later, XDP is queried to check if packets are being dropped at the specified interface.

The contents of the rule file are:

drop tcp any any -> any 5000 (msg: "Dropping TCP performance test traffic"; sid: 1; flow: established, to_server;)

This rule allows the connection to be established and traffic to be dropped later.

Scenario

Step 1: Run command file copy http://10.215.168.1/~robot/drop-performance.rules running://drop-performance.rules force at DUT0 and expect this output:

Show output
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

100   200  100   200    0     0  16666      0 --:--:-- --:--:-- --:--:-- 16666

Step 2: Set the following configuration in DUT0:

set service firewall FW ruleset file running://drop-performance.rules
set service firewall FW mode inline queue FW_Q
set service firewall FW logging outputs fast
set service firewall FW logging level config
set service firewall FW validator-timeout 20
set interfaces ethernet eth0 traffic policy in FW_PWAN
set interfaces ethernet eth0 traffic policy out FW_PWAN
set interfaces ethernet eth1 vif 101 traffic policy in FW_PLAN
set interfaces ethernet eth1 vif 201 traffic policy in FW_PLAN
set traffic queue FW_Q elements 1
set traffic policy FW_PWAN
set traffic policy FW_PLAN
set traffic selector FW_SEL
set traffic policy FW_PLAN rule 1 action enqueue FW_Q
set traffic policy FW_PWAN rule 1 action enqueue FW_Q
set service firewall FW stream bypass action drop set xdp-early-drop eth1

Step 3: Ping IP address 20.0.0.2 from DUT1:
