Chapter 4: Understanding Policy Configuration Proxy rule basics 116 Figure 49: Sample Network Configuration Table 14: Optional proxy rule options Optional Rule Criteria Setting Comments User Group marketing Specify the name of a user group. Authentication Password Specify the authentication method(s). FTP and Telnet proxies and console logins can also specify Password, Radius, SafeWord, SecurID, or SNK. Times/Day Mon-Fri 7am-7pm Important: If you are not using SSO, user groups can be used in an allow rule only if the specified service supports authentication (login, Telnet, FTP, Web, or secure shell [SSH]). Example of proxy rules using netgroups Specify the time restrictions for allowing or denying service. For the configuration shown in Figure 13, the Sidewinder G2 administrator has grouped all internal systems into one of three netgroups: marketing (mkt_net_group), engineering (eng_net_group), and accounting (acct_net_group). Note: For more information on netgroups, see “Network objects” on page 105. mkt_net_grp eng_net_grp acct_net_grp internal burb 172.20.1.1 proxies Sidewinder G2 external burb 192.55.214.2 Internet 192.55.12.3
Chapter 4: Understanding Policy Configuration Proxy rule basics Suppose you want to allow all groups access to external FTP sites but only the engineering group access to FTP host 192.55.12.3. Table 15 shows the proxy rules in the order that they should be added to the rule group. Table 15: Proxy rules for sample configuration shown in Figure 49 Proxy rule Criteria Rule 1: allow_eng_ftp Rule 2: deny_other_ftp Service Type Proxy Proxy Proxy Service FTP FTP FTP Action Allow Deny Allow Rule 3: allow_oth_ftp Source Burb Internal Internal Internal Source eng_net_group any (leave blank) any (leave blank) Destination Burb Internet Internet Internet Destination 192.55.12.3 192.55.12.3 any (leave blank) User Group any (leave blank) any (leave blank) any (leave blank) Authentication SafeWord Times/Days Fri 7am-7pm Application Defense (FTP) Allow Put/Get deny_all Allow Put/Get The following list summarizes key points to consider for the proxy rules listed in Table 15. • Rule 1 allows all systems in the engineering group authenticated FTP access to IP address 192.55.12.3 on the Internet, but only on Friday between 7:00 a.m. and 7:00 p.m. • This rule requires users to authenticate themselves via SafeWord before an FTP connection is allowed. • Rule 2 denies all systems in the trusted burb named internal from FTP service to IP address 192.55.12.3 on the Internet. • Rule 3 allows FTP service from all systems in the internal trusted burb to any external system in the Internet burb. 117
