Introduction 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 Balarajah & Rossenhoevel Expires April 17, 2019 [Page 3] Internet-Draft Benchmarking for NGFW performance October 2018 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. 2. Requirements The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. 3. Scope 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. The document focuses on advanced, realistic, and reproducible testing methods. Additionally, it describes test bed environments, test tool requirements and test result formats. 4. Test Setup Test setup defined in this document is applicable to all benchmarking test scenarios described in Section 7. 4.1. Testbed Configuration 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 switch and router in the testbed as 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 Layer 3 device(s) between test equipment and DUT/SUT as shown in Figure 1. If the test equipment is capable to emulate layer 3 routing functionality and there is no need for test equipment ports aggregation, it is RECOMMENDED to configure the test setup as shown in Figure 2.

DUT/SUT Configuration 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, testers 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 Balarajah & Rossenhoevel Expires April 17, 2019 [Page 5] Internet-Draft Benchmarking for NGFW performance October 2018 described in Section 7. The table 1 below describes the RECOMMENDED sets of feature list which SHOULD be configured on the DUT/SUT. Based on customer use case, user can take a decision to 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. +---------------------------+ | NGFW | +------------------------------------------+ | | |Included |Added to| |DUT Features |Feature|in initial|future | | | |Scope |Scope | +------------------------------------------+ |SSL Inspection| x | x | | +------------------------------------------+ |IDS/IPS | x | x | | +------------------------------------------+ |Web Filtering | x | | x | +------------------------------------------+ |Antivirus | x | x | | +------------------------------------------+ |Anti Spyware | x | x | | +------------------------------------------+ |Anti Botnet | x | x | | +------------------------------------------+ |DLP | x | | x | +------------------------------------------+ |DDoS | x | | x | +------------------------------------------+ |Certificate | x | | x | |Validation | | | | +------------------------------------------+ |Logging and | x | x | | |Reporting | | | | +------------------------------------------+ |Application | x | x | | |Identification| | | | +----------------------+----------+--------+ Table 1: DUT/SUT Feature List In summary, DUT/SUT SHOULD be configured as follows: Balarajah & Rossenhoevel Expires April 17, 2019 [Page 6] Internet-Draft Benchmarking for NGFW performance October 2018 o All security inspection enabled o Disposition of all traffic is logged - Logging to an external device is permissible o CVEs matching the following characteristics when serving the NVD * CVSS Version: 2 * CVSS V2 Metrics: AV:N/Au:N/I:C/A:C * AV=Attack Vector, Au=Authentication, I=Integrity and A=Availability * CVSS V2 Severity: High (7-10) * If doing a group test the published start date and published end date should be the same o Geographical location filtering and Application Identification and Control configured to be triggered based on a site or application from the defined traffic mix 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 class 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 rule defined in the table 2 MUST be configured from top to bottom in correct order shown in the table. The configured access policy rule MUST NOT block the test traffic used for the benchmarking test scenarios.

Test Equipment Configuration In general, test equipment allows configuring parameters in different protocol level. These parameters thereby influencing the traffic flows which will be offered and impacting performance measurements. Balarajah & Rossenhoevel Expires April 17, 2019 [Page 8] Internet-Draft Benchmarking for NGFW performance October 2018 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 test setup section of each test scenario individually. 4.3.1. Client Configuration This section specifies which parameters SHOULD be considered while configuring clients using test equipment. Also, this section specifies the recommended values for certain parameters. 4.3.1.1. TCP Stack Attributes The TCP stack SHOULD use a TCP Reno variant, which include congestion avoidance, back off and windowing, retransmission, and 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 32768 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. 4.3.1.2. Client IP Address Space 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] (Idea 1) 6-7 Mbps per IP (e.g. 1,400-1,700 IPs per 10Gbit/s throughput) (Idea 2) 0.1-0.2 Mbps per IP (e.g. 50,000-100,000 IPs per 10Gbit/s throughput) Balarajah & Rossenhoevel Expires April 17, 2019 [Page 9] Internet-Draft Benchmarking for NGFW performance October 2018 Based on deployment and use case scenario, client IP addresses SHOULD be distributed between IPv4 and IPv6 type. This document recommends using the following ratio(s) between IPv4 and IPv6: (Idea 1) 100 % IPv4, no IPv6 (Idea 2) 80 % IPv4, 20 % IPv6 (Idea 3) 50 % IPv4, 50 % IPv6 (Idea 4) 0 % IPv4, 100 % IPv6 4.3.1.3. Emulated Web Browser Attributes The emulated web browser contains attributes that will materially affect how traffic is loaded. The objective is to emulate a 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 tests MUST use TLSv1.2 or higher with a record size of 16383, commonly used cipher suite and key strength. Depending on test scenario, Session reuse or ticket resumption MAY be used for subsequent connections to the same Server endpoint IP. The client endpoint MUST send TLS Extension Server Name Indication (SNI) information when opening a security tunnel. Cipher suite and certificate size should be defined in the parameter session of each test scenario. 4.3.2. Backend Server Configuration This document specifies which parameters should be considerable while configuring emulated backend servers using test equipment. 4.3.2.1. TCP Stack Attributes The TCP stack SHOULD use a TCP Reno variant, which include congestion avoidance, back off and windowing, retransmission, and recovery on every TCP connection between client and server endpoints. The default IPv4 and IPv6 MSS segment size MUST be set to 1460 bytes and Balarajah & Rossenhoevel Expires April 17, 2019 [Page 10] Internet-Draft Benchmarking for NGFW performance October 2018 1440 bytes respectively and a TX and RX receive windows of at least 32768 bytes. 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. 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. 4.3.2.2. Server Endpoint IP Addressing 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. 4.3.2.3. HTTP / HTTPS Server Pool Endpoint Attributes The server pool for HTTP SHOULD listen on TCP port 80 and emulate HTTP version 1.1 with persistence. The server MUST advertise a server type. For HTTPS server, TLS 1.2 or higher MUST be used with a record size of 16383 bytes and ticket resumption or Session ID reuse SHOULD be enabled based on test scenario. 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 certificate size should be defined in the parameter section of each test scenario. 4.3.3. Traffic Flow Definition The section describes the traffic pattern between the client and server endpoints. At the beginning of the test, the server endpoint initializes and will be in a ready to accept connection state 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 the 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). Balarajah & Rossenhoevel Expires April 17, 2019 [Page 11] Internet-Draft Benchmarking for NGFW performance October 2018 4.3.3.1. Description of Intra-Client Behavior 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 initialized, the client should randomly hold (perform no operation) for a few milliseconds to allow for better randomization of start of client traffic. The client will then 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 or may not 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. 4.3.4. Traffic Load Profile 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. During the Init phase, test bed devices including the client and server endpoints should negotiate layer 2-3 connectivity such as MAC learning and ARP. Only after successful MAC learning or ARP/ND resolution shall the test iteration move to the next phase. No measurements are made in this phase. The minimum RECOMMEND time for Init phase is 5 seconds. During this phase, the emulated clients SHOULD NOT initiate any sessions with the DUT/SUT, in contrast, the emulated servers should be ready to accept requests from DUT/SUT or from emulated clients. In the ramp up phase, the test equipment SHOULD start to generate the test traffic. It SHOULD use a set approximate number of unique client IP addresses actively to generate traffic. The traffic should ramp from zero to desired target objective. The target objective will be defined for each benchmarking test. The duration for the ramp up phase MUST be configured long enough, so that the test equipment does not overwhelm DUT/SUT's supported performance metrics namely; connections per second, concurrent TCP connections, and application transactions per second. The RECOMMENDED time duration Balarajah & Rossenhoevel Expires April 17, 2019 [Page 12] Internet-Draft Benchmarking for NGFW performance October 2018 for the ramp up phase is 180-300 seconds. No measurements are made in this phase. In the sustain phase, the test equipment SHOULD continue generating traffic to constant target value for a constant number of active client IPs. The RECOMMENDED time duration for sustain phase is 600 seconds. This is the phase where measurements occur. In the ramp down/close phase, no new connections are established, and no measurements are made. The time duration for ramp up and ramp down phase SHOULD be same. The RECOMMENDED duration of this phase is between 180 to 300 seconds. The last phase is administrative and will be when the tester merges and collates the report data. 5. Test Bed Considerations This section recommends steps to control the test environment and test equipment, specifically focusing on virtualized environments and virtualized test equipment. 1. Ensure that any ancillary switching or routing functions between the system under test and the test equipment do not limit the performance of the traffic generator. This is specifically important for virtualized components (vSwitches, vRouters). 2. Verify that the performance of the test equipment matches and reasonably exceeds the expected maximum performance of the system under test. 3. Assert that the test bed characteristics are stable during the entire test session. Several factors might influence stability specifically for virtualized test beds, for example additional workloads in a virtualized system, load balancing and movement of virtual machines during the test, or simple issues such as additional heat created by high workloads leading to an emergency CPU performance reduction. 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.

The value of throughput SHOULD be presented in Gbit/s rounded to two places of precision with a more specific kbps in parenthesis. Optionally, goodput MAY also be logged as an average goodput rate measured over the same period. Goodput result SHALL also be presented in the same format as throughput. o URL Response time / Time to Last Byte (TTLB) This key performance indicator measures the minimum, average and maximum per URL response time in the sustaining period. The latency is measured at Client and in this case would be the time duration between sending a GET request from Client and the receival of the complete response from the server. o Application Transaction Latency This key performance indicator measures the minimum, average and maximum the amount of time to receive all objects from the server. The value of application transaction latency SHOULD be presented in millisecond rounded to zero decimal. o Time to First Byte (TTFB) This key performance indicator will measure minimum, average and maximum the time to first byte. TTFB is the elapsed time between sending the SYN packet from the client and receiving the first byte of application date from the DUT/SUT. TTFB SHOULD be expressed in millisecond. 7.

Number of Terminated TCP connections due to unexpected TCP RST sent by DUT/SUT MUST be less than 0.01% of total initiated TCP connections c. During the sustain phase, traffic should be forwarded constantly at the rate defined in the parameter section 7.11.3.2 d. During the sustain phase, then maximum deviation (max. dev) of application transaction latency or TTLB (Time To Last Byte) MUST be less than 10% 7.11.3.4. Measurement Following KPI metrics MUST be reported for this test scenario: Average Throughput, max. Min. Avg. Concurrent TCP connections, TTLB/ application transaction latency and average application transactions per second 7.11.4. Test Procedures and expected Results The test procedure is designed to measure the concurrent TCP connection capacity of the DUT/SUT at the sustaining period of traffic load profile. The test procedure consists of three major steps. This test procedure MAY be repeated multiple times with different IPv4 and IPv6 traffic distribution. 7.11.4.1. Step 1: Test Initialization and Qualification Verify the link status of the all connected physical interfaces. All interfaces are expected to be "UP" status. Configure test equipment to generate background traffic ad defined in section 7.3.11.2. Measure throughput, concurrent TCP connections, and connections per second. While generating the background traffic, configure another traffic profile on the test equipment to establish "initial concurrent TCP connections" defined in the section 7.11.3.2. The traffic load Balarajah & Rossenhoevel Expires April 17, 2019 [Page 52] Internet-Draft Benchmarking for NGFW performance October 2018 profile CAN be defined as described in the section Error: Reference source not found During the sustain phase, the DUT/SUT SHOULD reach the "initial concurrent TCP connections" plus concurrent TCP connections measured in background traffic. The measured KPIs during the sustain phase MUST meet the acceptance criteria "a" and "b" defined in the section Error: Reference source not found If the KPI metrics do not meet the acceptance criteria, the test procedure MUST NOT be continued to "Step 2". 7.11.4.2. Step 2: Test Run with Target Objective Configure test equipment to establish "Target concurrent TCP connections" minus concurrent TCP connections measured in background traffic. The test equipment SHOULD follow the traffic load profile definition as described in the section 4.3.4 During the ramp up and sustain phase, the other KPIs such as throughput, TCP connections per second and application transactions per second MUST NOT reach to the maximum value that the DUT/SUT can support. The test equipment SHOULD start to measure and record KPIs defined in section 7.11.3.4. The frequency of measurement MUST be less than 5 seconds. Continue the test until all traffic profile phases are completed. The DUT/SUT is expected to reach the desired target concurrent TCP connections at the sustain phase. In addition, the measured KPIs must meet all acceptance criteria. Follow the step 3, if the KPI metrics do not meet the acceptance criteria. 7.11.4.3. Step 3: Test Iteration Determine the maximum and average achievable concurrent TCP connections within the acceptance criteria. 8. Formal Syntax 9.

NetSecOPEN Basic 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: o Clients connecting to multiple different server FQDNs per application o Clients loading apps and pages with connections and objects in specific orders o Multiple unique certificates for HTTPS/TLS o A wide variety of different object sizes o Different URL paths o Mix of HTTP and HTTPS 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: o HTTP HOST based application detection o HTTPS/TLS Server Name Indication (SNI) o Certificate Subject Common Name (CN) 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: o Thousands of URLs each client walks thru o Hundreds of FQDNs each client connects to o Hundreds of unique certificates for HTTPS/TLS o Thousands of different object sizes per client in orders matching applications Balarajah & Rossenhoevel Expires April 17, 2019 [Page 55] Internet-Draft Benchmarking for NGFW performance October 2018 The following is a description of what a popular application in an enterprise traffic mix contains.
