IntroductionWith more and more corporate data being placed on corporate networks, it is vitally important to protect that data from malicious activities.

An Intrusion Prevention System (IPS) is designed to detect malicious activities and drop or sanitize the packets while allowing legitimate

traffic to access the corporate network. Thoroughly testing IPS devices is essential to ensuring that they work properly. If the IPS device is

not working properly, malicious traffic containing viruses, worms and backdoors can easily gain access to the corporate network and cause

a great deal of problems, potentially bringing down the network.

Performing a series of measurements using the BreakingPoint Storm CTM on the IPS will help determine the actual performance, security

and stability of the IPS under real world conditions. For instance, the IPS device might be able to detect and mitigate malicious activity

when network traffic is light. However, when network traffic becomes heavy, the IPS device might detect significantly less malicious activity.

Using the BreakingPoint Storm CTM you can expose previously impossible to detect vulnerabilities in your IPS before they are exploited to

compromise your customer data, corporate assets, brand reputation and even nation security.

The test environment should emulate the actual deployment environment as closely as possible. Directly connected devices such as routers,

switches and firewalls will have an effect on packet loss, latency and data integrity. The number of advertised host IP and MAC addresses,

VLAN Tagging, and NAT will also affect the performance of an IPS.

If it is not feasible to fully recreate the deployment environment, the BreakingPoint Storm CTM should be connected directly to the IPS.

All IPS devices and builds being evaluated must use the same test environment to ensure consistent results.

Baseline Application Performance: Maximum Connections

Determine the number of connections per second that the IPS is able to handle. This will validate the performance of the IPS when

sending only good traffic with an “Allow All” policy. The TCP setup time will be analyzed to determine how a greater number of TCP

connections per second affect the time it takes to establish the TCP connection.

Baseline Application Performance: Throughput

Determine the throughput that the IPS is able to handle. This will validate the throughput performance the IPS is able to handle when

sending only good traffic with an “Allow All” policy. The overall throughput that the IPS is able to support will be determined.

Baseline Attack Mitigation Traffic: SYN Flood

Determine a baseline measurement for how the IPS performs when handling a SYN flood. Once a baseline has been established, it will

be compared with the results from the tests that blend both application and malicious traffic. The number of attempted sessions for the

SYN flood will be determined as well as the number of attempted sessions for the SYN flood that were blocked by the IPS.

Baseline Attack Mitigation Traffic: Malicious Traffic

Determine the ability of the IPS to remain stable while vulnerabilities, worms and backdoors are transmitted through it. To

perform this test, the BreakingPoint Storm CTM will be configured to use an Attack Series that includes high-risk vulnerabilities, worms and

backdoors. IPS devices have functionality that may block some of the attacks. The number of attacks blocked by the IPS will be determined

as well as the number of attacks that were able to pass through the IPS.

Application Traffic with SYN Flood

Determine a baseline measurement for how the IPS performs when handling a malicious SYN flood. Once a baseline has been

established, it will be compared with the results from the tests that blend both application and malicious traffic. The number of attempted

sessions for the SYN flood will be determined as well as the number of attempted sessions for the SYN flood that were blocked by the IPS.

Application Traffic with Malicious Traffic

Determine the ability of the IPS to remain stable while vulnerabilities, worms and backdoors are transmitted through it. To

perform this test, the BreakingPoint Storm CTM will be configured to use an Attack Series that includes high-risk vulnerabilities, worms and

backdoors.

Application Traffic with Malicious Traffic and SYN Flood

This test determines the ability of the IPS to handle application traffic, a SYN flood and malicious traffic. The results will be compared

to both the Throughput Test and the SYN Flood Test. Again, the IPS’s ability to detect and mitigate a SYN flood will be determined. Also, the

effect of the malicious traffic on the application traffic’s throughput, latency time-to-open, and time-to-close will be analyzed. Finally, the

IPS’s ability to detect and mitigate the same number of attacks as in the previous Security tests will be tested.

Jumbo Frames

This test uses the Throughput test, except the Maximum Segment Size (MMS) parameter will be increased. The maximum

transmission unit (MTU) size of the port will be verified and increased if needed. This test will determine if the IPS was able to perform

better, worse or the same when handling jumbo frames. These results will be compared to those from the Throughput Test.

IP, UDP and TCP Fuzzing

The BreakingPoint Storm CTM will be configured to use the Stack Scrambler component. This test component has the ability to

send malformed IP, UDP, TCP and Ethernet packets to the IPS. The fuzzing technique will modify parts of the packet, such as checksums

and protocol options, to generate the corrupted data. The IPS’s ability to handle malformed packets will be determined. Take notice if

the IPS crashes during the test, as this is the most important sign that the IPS is not able to appropriately handle the malformed packets.

Also, analyze the effects the malformed packets had on the application traffic and determine if the IPS’s attack detection and mitigation

capabilities were affected.

Protocol Fuzzing

This test will utilize the Security test component. This time the Security test component will fuzz application layer frames. The IPS’s ability

to handle malformed application layer frames will be determined.

Evasion Techniques

The Application Traffic with Malicious Traffic test will be used as a starting point for this test. The Security test component will have

changes made to its configuration. These changes will configure different evasion techniques that might create false negatives.

Negative Testing

The Maximum Connections test will be used as a starting point. Changes will then be made to a Super Flow. This Super Flow will then be

sent through the IPS. It will be determined how well the IPS unit was able to handle the negative testing.

Baseline Application Performance: Maximum Connections

RFC:• RFC 793 – Transmission Control Protocol

Overview:

The specifications from the IPS data sheet will be used to determine if the IPS meets or exceeds the stated capacity. To determine the

capabilities, a Session Sender test component will be used to push the IPS beyond its stated supported limits.

Baseline Application Performance: Throughput

RFC:• RFC 768 – User Datagram Protocol

• RFC 791 – Internet Protocol

• RFC 793 – Transmission Control Protocol

Overview:A similar test setup as the previous one will be used. An Application Simulator test component will be used to generate, at maximum, 33% of the effective session capacity of the IPS as determined in the previous test, while trying to maximize throughput.

• Increase the duration of the test time.

Baseline Attack Mitigation: SYN Flood

RFC:• RFC 793 – Transmission Control Protocol

• RFC 4987 – TCP SYN Flooding Attacks and Common Mitigations

Overview:

A SYN Flood is when a client starts a TCP connection but never sends an ACK and keeps trying to initiate TCP connections. This is harmful

to an IPS, as it has to provide resources to the TCP connection requests. The IPS likely has the ability to detect and prevent the SYN Flood. A

Session Sender test component will be used to create a SYN Flood to attack the IPS.

Objective:

To evaluate the IPS’s ability to detect and mitigate a SYN flood.

• Increase the test length for a longer SYN attack.

Baseline Attack Mitigation: Malicious Traffic

Overview:

It is important to evaluate how malicious traffic will affect the performance of an IPS. A Security test component will be used in this test.

Five default attack series are available to use, but during this test only Security Level 1 will be used. Security Level 1 includes high-risk

vulnerabilities in services often exposed to the Internet.

Objective:

To evaluate the IPS’s ability to detect and mitigate vulnerabilities, worms and backdoors.

• Use different presets, such as the Service Provider App or a custom application profile.

• Use a different random seed.

Application Traffic with SYN Flood

Overview:

Since tests for application performance and a SYN Flood have already been configured and saved as presets, they will be used in this test.

Two test components will be used during this test, an Application Simulator and a Session Sender component.

Application Traffic with Malicious Traffic and SYN Flood

Overview:

Since tests for application performance, malicious traffic and a SYN Flood have already been configured and saved as presets, they will be

used in this test. Three test components will be used during this test, an Application Simulator, a Security component and a Session Sender

component. This test will determine the ability of the IPS to handle malicious traffic while also having to deal with a SYN Flood and allowing

good traffic to pass through.

Objective:

To send a blend of application traffic with a SYN Flood and malicious traffic to the IPS and to compare the results of this test against the

results of the baseline tests.

IP, UDP and TCP Fuzzing

Overview:

The Throughput test will be used as a starting point and a Stack Scrambler component will be used too. The Stack Scrambler tests the

integrity of different protocols by sending malformed IP, UDP, TCP and Ethernet packets to the IPS. The fuzzing technique will modify only a

single part of the packet to generate corrupt data.

Objective:

To send fuzzed traffic through the IPS and determine how it affects the IPS and other protocols.
