3 Terms and Definitions
For the purposes of this document, the terms and definitions established in GB/T 25069-2010 and the following ones apply.
3.1
Firewall
Security gateway products which are allocated among security domains to control and filter the access to network layer and with the function of application layer protocol analyses, control and contents testing, which are applicable to IPv4 and IPv6.
3.2
Deep packet inspection
It is based on flow testing and control technology of application layer and will obtain all the application program contents by reading IP packet loads and reconstructing the information of application layer and then it also deal with the contents depending on the policy of system definition.
3.3
Deep content inspection
It is able to make a deep analyses for application protocol, identifies all elements therein (such as HTTP protocol, specifically cookie, Get parameters and Post form) and all the protocol service (such as data contents included in the protocol or documents in the business system interaction) and then analyze quickly the data to restore the original communicating information. It also can test whether threat or sensitive contents are included based on the original information.
3.4
SQL injection
Its purpose is to cheat the server into doing malicious SQL command by inserting SQL command into submittal or page request parameters of web form.
3.5
Cross site scripting
A type of injection, in which the malicious HTML code is injected into a web page by the malicious attacker. The HTML code will be executed when the user browses the page so as to realize malicious attack to the user.
4 Abbreviated Terms
For the purpose of this document, the following abbreviated terms apply.
DPI: Deep packet inspection
DCI: Deep content inspection
SQL: Structured Query Language
XSS: Cross Site Scripting
5 Firewall Description
The firewall is to establish security control points in security fields, analyze and filter data flow through firewall according to predefined access control policy and security protection policy, and provide controllable visit service request to the protected security field. The firewall protocol suite compatible with the next generation of net atmosphere supports not only IPv4 technology but also IPv6, IPv4/IPv6 transition technology.
Firewall protected assets include the network service and resource under the protection of security policy as well as firewall itself and important internal data. The firewall is operated in the route or transparency mode and the network is categorized as security fields, in which the security policy is used for auditing and control of the service and visits.
Figure 1 shows a typical operating atmosphere of firewall, which divides the network into intranet, extranet and DMZ. Intranet is a trusted region, extranet is an untrusted region and DMZ server may provide application services to the users in extranet and intranet.
