Table 18: Dynamic Blacklist parameters
Parameter Description Associated default condition

Checking for a blacklisted IP address

The following procedure explains how the Security Analytics Engine checks the IP address against one or more blacklists to determine if the access attempt is from a blacklisted IP address.

How the Security Analytics Engine checks for a blacklisted IP address

  1. A user attempts to access an application that uses a Dynamic Blacklist condition type to check if an IP address is on a blacklist.
  2. The Security Analytics Engine compares the IP address used in the access attempt against the blacklists currently enabled for the BlacklistProviderPlugin. If this check returns as true (the IP address is included in a blacklist), the risk score is increased.
  3. If this check returns as false (the IP address is not in a blacklisted network), the risk score is not affected.

Network List

 NOTE: The BuiltinPlugin is associated with this condition and provides important settings.

Categorized as a Network condition, this type of condition determines if the request originates from a specific IP address. The following parameters are available:

Table 19: Network List parameters

Whitelist (Default)

Description

Enter a description for the condition.

Originated from a whitelisted IP address range.

Risk Type Value

Select the impact the condition will have on the risk score:

  • Can increase risk - Selecting this option causes the risk score to increase if the access attempt comes from a listed network.
  • Can decrease risk - Selecting this option causes the condition score to decrease if the access attempt comes from a listed network. A condition with this setting can only be used as a modifier in a risk policy.
  • Can both increase or decrease risk - Selecting this check box allows you to configure the risk score to either increase or decrease.

NOTE: In order to avoid application configuration errors, this parameter cannot be edited once the condition has been saved.

Checking for a specific network

The following procedure explains how the Security Analytics Engine checks the IP address to determine if the access attempt is from a listed network.

How the Security Analytics Engine checks for specific networks

  1. A user attempts to access an application that uses a Network List condition type to check if an IP address is in a listed network.

  2. The Security Analytics Engine compares the IP address used in the access attempt against the list of networks. If this check returns as true (the IP address is in a listed network), the risk score is affected.

    		 NOTE: If the Include Local IP Addresses parameter is selected and a loopback IP address is configured in the list, the Security Analytics Engine will also return true if the IP address used is one of the local IP addresses configured on the web server.
  3. If this check returns as false (the IP address is not in a listed network), the risk score is not affected.
