This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents"
This document replaces GB/T 28451-2012 "Technical requirements and test evaluation methods for network-based intrusion prevention products of information security technology"
Compared with GB/T 28451-2012, except for structural adjustment and editorial changes, the main technical changes are as follows:
a) Added the requirement of "flow control" (see 6:1:1:5);
b) Added the requirement of "retention of attack data" (see 6:1:3:5);
c) Added the requirement of "configuration backup and restoration" (see 6:1:4:6);
d) Added the requirement of "outgoing logs" (see 6:1:4:12);
e) Added performances such as "Network Layer Throughput", "Mixed Application Layer Throughput", "TCP New Connection Rate", "TCP Concurrent Connections", etc:
Specific content of requirements (see 6:3:1, 6:3:2, 6:3:3 and 6:3:4);
f) Added the specific requirements for product misinterception rate and missed interception rate (see 6:3:5, 6:3:6, 7:4 of the:2012 edition);
g) The content of the chapter "Environmental Adaptability Requirements" has been added, which mainly clarifies the product's ability to support IPv6, including IPv6
Application environment adaptability, IPv6 management environment adaptability, dual protocol stack, and virtualization support capability (see 6:4);
h) Removed the "load balancing" requirement (see 7:3:1:4:9 of the:2012 edition);
i) Change "Technical Requirements for Intrusion Prevention Products" to "Security Function Requirements", and "Security Requirements for Products" to "Self-Security Requirements"
Requirements", "Product Assurance Requirements" changed to "Safety Assurance Requirements" (see Chapter 6, 7 and 8 of the:2012 edition);
j) Changed the classification of intrusion prevention products, from "Level 1, Level 2 and Level 3" to "Basic Level and Enhanced Level" (see Appendix
A, 7:1, 7:2 and 7:3 of the:2012 edition):
