Oracle WebLogic must protect against or limit the effects of HTTP types of Denial of Service (DoS) attacks.

Finding ID	Version	Rule ID	IA Controls	Severity
V-235989	WBLC-08-000236	SV-235989r628745_rule		Medium

Description
Employing increased capacity and bandwidth combined with service redundancy can reduce the susceptibility to some DoS attacks. When utilizing an application server in a high risk environment (such as a DMZ), the amount of access to the system from various sources usually increases, as does the system's risk of becoming more susceptible to DoS attacks. The application server must be able to be configured to withstand or minimize the risk of DoS attacks. This can be partially achieved if the application server provides configuration options that limit the number of allowed concurrent HTTP connections.

1. Access AC 2. From 'Domain Structure', select 'Deployments' 3. Sort 'Deployments' table by 'Type' by click the column header 4. Select an 'Enterprise Application' or 'Web Application' to check the session timeout setting 5. Select 'Configuration' tab -> 'Application' tab for deployments of 'Enterprise Application' type Select 'Configuration' tab -> 'General' tab for deployments of 'Web Application' type 6. Ensure 'Maximum in-memory Session' field value is set to an integer value at or lower than an acceptable maximum number of HTTP sessions If a value is not set in the 'Maximum in-memory Session' field for all deployments, this is a finding.
