Configuring IP Address Blacklist and Whitelist Rules to Block or Allow Specified IP Addresses

Prerequisites

A protected website has been added. For details, see Adding a Website to EdgeSec.

Constraints

• EdgeSec supports batch import of IP address blacklists and whitelists. You can use address groups to add multiple IP addresses or IP address ranges quickly to a blacklist or whitelist rule. For details, see Adding a Blacklist or Whitelist IP Address Group.
• It takes several minutes for a new rule to take effect. After the rule takes effect, protection events triggered by the rule will be displayed on the Events page.
• The address 0.0.0.0/0 cannot be added to the IP address blacklist or whitelist, and if a whitelist conflicts with a blacklist, the whitelist rule takes priority. If you want to allow only a specific IP address within a range of blocked addresses, add a blacklist rule to block the range and then add a whitelist rule to allow the individual address you wish to allow.
• If you configure Protective Action to Block for a blacklist or whitelist rule, you can configure a known attack source rule by referring to Configuring a Known Attack Source Rule. EdgeSec will block requests matching the configured IP address, Cookie, or Params for a length of time configured as part of the rule.

Precautions

• If you configure an IP address blacklist/whitelist rule in both EdgeSec and CDN, the blacklist/whitelist rule in CDN is executed first.
• If the quota of IP address whitelist and blacklist rules of your EdgeSec instance cannot meet your requirements, you can purchase rule expansion packages under the current EdgeSec instance edition (a rule expansion package allows you to configure up to 10 IP address blacklist and whitelist rules) to increase such quota.

Impact on the System

If an IP address is added to a blacklist or whitelist, EdgeSec blocks or allows requests from that IP address without checking whether the requests are malicious.

Procedure

1. Log in to the management console.
2. Click in the upper left corner of the page and choose Security & Compliance > Edge Security.

7. In the upper left corner of the Blacklist and Whitelist page, click Add Rule.
8. In the displayed dialog box, add a blacklist or whitelist rule, as shown in Figure 3.
   

   • If you select Log only for Protective Action for an IP address, EdgeSec only identifies and logs requests from the IP address.
   • Other IP addresses are evaluated based on other configured EdgeSec protection rules.

Example Configuration - Allowing a Specified IP Addresses

If domain name www.example.com has been connected to EdgeSec, you can perform the following steps to verify the rule takes effect:

1. Add the following two blacklist and whitelist rules to block all IP addresses:
   Figure 4 Blocking IP address range 1.0.0.0/1
   
   Figure 5 Blocking IP address range 128.0.0.0/1
   

   You can also add a precise protection rule to block all access requests, as shown in Figure 6.

   Figure 6 Blocking all access requests
   

   For details, see Configuring a Precise Protection Rule.

2. Refer to Figure 7 and add a whitelist rule to allow a specified IP address, for example, XXX.XXX.2.3.

3. Enable the white and blacklist protection.

4. Clear the browser cache and access http://www.example.com.

   If the IP address of a visitor is not the one specified in 2, EdgeSec blocks the access request. Figure 9 shows an example of the block page.
