15 years have passed since IETF recommended test methodology and terminology for firewalls initially ([RFC2647], [RFC3511]). The requirements for network security element performance and effectiveness have increased tremendously since then. Security function implementations have evolved to more advanced areas and have diversified into intrusion detection and prevention, threat management, analysis of encrypted traffic, etc. In an industry of growing importance, well-defined and reproducible key performance indicators (KPIs) are increasingly needed: They enable fair and reasonable comparison of network security functions. All these reasons have led to the creation of a new next-generation firewall benchmarking document.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", “NOT RECOMMENDED”, "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119], [RFC8174] when, and only when, they appear in all capitals, as shown here.
This document provides testing terminology and testing methodology for next-generation firewalls and related security functions. It covers two main areas: Performance benchmarks and security effectiveness testing. This document focuses on advanced, realistic, and reproducible testing methods. Additionally, it describes test bed environments, test tool requirements and test result formats.
Test setup defined in this document is applicable to all benchmarking test scenarios described in Section 7.
Testbed configuration MUST ensure that any performance implications that are discovered during the benchmark testing aren't due to the inherent physical network limitations such as number of physical links and forwarding performance capabilities (throughput and latency) of the network devise in the testbed. For this reason, this document recommends avoiding external devices such as switches and routers in the testbed wherever possible.
However, in the typical deployment, the security devices (DUT/SUT) are connected to routers and switches which will reduce the number of entries in MAC or ARP tables of the DUT/SUT. If MAC or ARP tables have many entries, this may impact the actual DUT/SUT performance due to MAC and ARP/ND table lookup processes. Therefore, it is RECOMMENDED to connect aggregation switches or routers between test equipment and DUT/SUT as shown in Figure 1. The aggregation switches or routers can be also used to aggregate the test equipment or DUT/SUT ports, if the numbers of used ports are mismatched between test equipment and DUT/SUT.
If the test equipment is capable of emulating layer 3 routing functionality and there is no need for test equipment port aggregation, it is RECOMMENDED to configure the test setup as shown in Figure 2.

Figure 2: Testbed Setup - Option 2
A unique DUT/SUT configuration MUST be used for all benchmarking tests described in Section 7. Since each DUT/SUT will have their own unique configuration, users SHOULD configure their device with the same parameters that would be used in the actual deployment of the device or a typical deployment. Users MUST enable security features on the DUT/SUT to achieve maximum security coverage for a specific deployment scenario.
This document attempts to define the recommended security features which SHOULD be consistently enabled for all the benchmarking tests described in Section 7. Table 1 below describes the RECOMMENDED sets of feature list which SHOULD be configured on the DUT/SUT.
Based on customer use case, users MAY enable or disable SSL inspection feature for “Throughput Performance with NetSecOPEN Traffic Mix” test scenario described in Section 7.1
To improve repeatability, a summary of the DUT configuration including description of all enabled DUT/SUT features MUST be published with the benchmarking results.

Table 1: DUT/SUT Feature List
In summary, DUT/SUT SHOULD be configured as follows:
In addition, it is also RECOMMENDED to configure a realistic number of access policy rules on the DUT/SUT. This document determines the number of access policy rules for three different classes of DUT/SUT. The classification of the DUT/SUT MAY be based on its maximum supported firewall throughput performance number defined in the vendor data sheet. This document classifies the DUT/SUT in three different categories; namely small, medium, and maximum.
The RECOMMENDED throughput values for the following classes are:
Extra Small (XS) - supported throughput less than 1Gbit/s
Small (S) - supported throughput less than 5Gbit/s
Medium (M) - supported throughput greater than 5Gbit/s and less than 10Gbit/s
Large (L) - supported throughput greater than 10Gbit/s
The Access Conrol Rules (ACL) defined in Table 2 SHOULD be configured from top to bottom in the correct order as shown in the table. (Note: There will be differences between how security vendors implement ACL decision making.) The configured ACL MUST NOT block the test traffic used for the benchmarking test scenarios.

Table 2: DUT/SUT Access List
In general, test equipment allows configuring parameters in different protocol layers. These parameters thereby influence the traffic flows which will be offered and impact performance measurements.
This document specifies common test equipment configuration parameters applicable for all test scenarios defined in Section 7. Any test scenario specific parameters are described under the test setup section of each test scenario individually.
This section specifies which parameters SHOULD be considered while configuring clients using test equipment. Also, this section specifies the recommended values for certain parameters.
The TCP stack SHOULD use a TCP Reno [RFC5681] variant, which include congestion avoidance, back off and windowing, fast retransmission, and fast recovery on every TCP connection between client and server endpoints. The default IPv4 and IPv6 MSS segments size MUST be set to 1460 bytes and 1440 bytes respectively and a TX and RX receive windows of 65536 bytes. Client initial congestion window MUST NOT exceed 10 times the MSS. Delayed ACKs are permitted and the maximum client delayed Ack MUST NOT exceed 10 times the MSS before a forced ACK. Up to 3 retries SHOULD be allowed before a timeout event is declared. All traffic MUST set the TCP PSH flag to high. The source port range SHOULD be in the range of 1024 - 65535. Internal timeout SHOULD be dynamically scalable per RFC 793. Client SHOULD initiate and close TCP connections. TCP connections MUST be closed via FIN.
The sum of the client IP space SHOULD contain the following attributes. The traffic blocks SHOULD consist of multiple unique, discontinuous static address blocks. A default gateway is permitted. The IPv4 ToS byte or IPv6 traffic class should be set to '00' or ‘000000’ respectively.
The following equation can be used to determine the required total number of client IP address.
Desired total number of client IP = Target throughput [Mbit/s] / Throughput per IP address [Mbit/s]
Based on deployment and use case scenario, the value for "Throughput per IP address" can be varied.
Based on deployment and use case scenario, client IP addresses SHOULD be distributed between IPv4 and IPv6 type. The Following options can be considered for a selection of traffic mix ratio.
The emulated web browser contains attributes that will materially affect how traffic is loaded. The objective is to emulate modern, typical browser attributes to improve realism of the result set.
For HTTP traffic emulation, the emulated browser MUST negotiate HTTP 1.1. HTTP persistency MAY be enabled depending on test scenario. The browser MAY open multiple TCP connections per Server endpoint IP at any time depending on how many sequential transactions are needed to be processed. Within the TCP connection multiple transactions MAY be processed if the emulated browser has available connections. The browser SHOULD advertise a User-Agent header. Headers MUST be sent uncompressed. The browser SHOULD enforce content length validation.
For encrypted traffic, the following attributes SHALL define the negotiated encryption parameters. The test clients MUST use TLSv1.2 or higher. TLS record size MAY be optimized for the HTTPS response object size up to a record size of 16 KByte. The client endpoint MUST send TLS Extension Server Name Indication (SNI) information when opening a security tunnel. Each client connection MUST perform a full handshake with servercertificate and MUST NOT use session reuse or resumption. Cipher suite and key size should be defined in the parameter session of each test scenario.
This document specifies which parameters should be considerable while configuring emulated backend servers using test equipment.
The TCP stack on the server side SHOULD be configured similar to the client side configuration described in Section 4.3.1.1. In addition, server initial congestion window MUST NOT exceed 10 times the MSS. Delayed ACKs are permitted and the maximum server delayed ACK MUST NOT exceed 10 times the MSS before a forced ACK.
The server IP blocks SHOULD consist of unique, discontinuous static address blocks with one IP per Server Fully Qualified Domain Name (FQDN) endpoint per test port. The IPv4 ToS byte and IPv6 traffic class bytes should be set to '00' and ‘000000’ respectively.
The server pool for HTTP SHOULD listen on TCP port 80 and emulate HTTP version 1.1 with persistence. The Server MUST advertise server type in the Server response header [RFC2616]. For HTTPS server, TLS 1.2 or higher MUST be used with a maximum record size of 16 KBytes and MUST NOT use ticket resumption or Session ID reuse . The server MUST listen on port TCP 443. The server SHALL serve a certificate to the client. It is REQUIRED that the HTTPS server also check Host SNI information with the FQDN. Cipher suite and key size should be defined in the parameter section of each test scenario.
This section describes the traffic pattern between client and server endpoints. At the beginning of the test, the server endpoint initializes and will be ready to accept connection states including initialization of the TCP stack as well as bound HTTP and HTTPS servers. When a client endpoint is needed, it will initialize and be given attributes such as a MAC and IP address. The behavior of the client is to sweep though the given server IP space, sequentially generating a recognizable service by the DUT. Thus, a balanced, mesh between client endpoints and server endpoints will be generated in a client port server port combination. Each client endpoint performs the same actions as other endpoints, with the difference being the source IP of the client endpoint and the target server IP pool. The client SHALL use Fully Qualified Domain Names (FQDN) in Host Headers and for TLS Server Name Indication (SNI).
Client endpoints are independent of other clients that are concurrently executing. When a client endpoint initiates traffic, this section describes how the client steps though different services. Once the test is initialized, the client endpoints SHOULD randomly hold (perform no operation) for a few milliseconds to allow for better randomization of start of client traffic. Each client will either open a new TCP connection or connect to a TCP persistence stack still open to that specific server. At any point that the service profile may require encryption, a TLS encryption tunnel will form presenting the URL request to the server. The server will then perform an SNI name check with the proposed FQDN compared to the domain embedded in the certificate. Only when correct, will the server process the HTTPS response object. The initial response object to the server MUST NOT have a fixed size; its size is based on benchmarking tests described in Section 7. Multiple additional sub-URLs (response objects on the service page) MAY be requested simultaneously. This MAY be to the same server IP as the initial URL. Each sub-object will also use a conical FQDN and URL path, as observed in the traffic mix used.
The loading of traffic is described in this section. The loading of a traffic load profile has five distinct phases: Init, ramp up, sustain, ramp down, and collection.
This section recommends steps to control the test environment and test equipment, specifically focusing on virtualized environments and virtualized test equipment.
Test bed reference pre-tests help to ensure that the desired traffic generator aspects such as maximum throughput and the network performance metrics such as maximum latency and maximum packet loss are met.
Once the desired maximum performance goals for the system under test have been identified, a safety margin of 10% SHOULD be added for throughput and subtracted for maximum latency and maximum packet loss.
Test bed preparation may be performed either by configuring the DUT in the most trivial setup (fast forwarding) or without presence of DUT.
This section describes how the final report should be formatted and presented. The final test report MAY have two major sections; Introduction and result sections. The following attributes SHOULD be present in the introduction section of the test report.
This section lists KPIs for overall benchmarking tests scenarios. All KPIs MUST be measured during the sustain phase of the traffic load profile described in Section 4.3.4. All KPIs MUST be measured from the result output of test equipment.
Using NetSecOPEN traffic mix, determine the maximum sustainable throughput performance supported by the DUT/SUT. (see Appendix A for details about traffic mix)

A traffic mix for testing performance of next generation firewalls MUST scale to stress the DUT based on real-world conditions. In order to achieve this the following MUST be included:
A traffic mix for testing performance of next generation firewalls MUST also facility application identification using different detection methods with and without decryption of the traffic. Such as:
The mix MUST be of sufficient complexity and volume to render differences in individual apps as statistically insignificant. For example, changes in like to like apps – such as one type of video service vs. another both consist of larger objects whereas one news site vs. another both typically have more connections then other apps because of trackers and embedded advertising content. To achieve sufficient complexity, a mix MUST have:

Clients MUST connect to multiple server FQDNs in the same order as real applications. Connections MUST be made when the client is interacting with the application and MUST NOT first setup up all connections. Connections SHOULD stay open per client for subsequent transactions to the same FQDN similar to how a web browser behaves. Clients MUST use different URL Paths and Object sizes in orders as they are observed in real Applications. Clients MAY also setup multiple connections per FQDN to process multiple transactions in a sequence at the same time.

Table 6: Office365 Word Transactions
For application identification the HTTPS/TLS traffic MUST include realistic Certificate Subject Common Name (CN) data as well as Server Name Indications (SNI). For example, a DUT MAY detect Facebook Chat traffic by inspecting the certificate and detecting *.facebook.com in the certificate subject CN and subsequently detect the word chat in the FQDN 5-edge-chat.facebook.com and identify traffic on the connection to be Facebook Chat.
Table 7 includes further examples in SNI and CN pairs for several FQDNs of Office 365.
