As such, settings must be high enough to allow for all data to reach the Trellix ePO.","checkContent":"From the ePO server console System Tree, select the \"Systems\" tab.\n\nSelect \"This Group and All Subgroups\".\n\nSelect the asset to be validated.\n\nSelect \"Actions\".\n\nSelect \"Agent\".\n\nSelect \"Modify Policies on a Single System\".\n\nFrom the product pull-down list, select Solidcore 8.x: General.\n\nFrom the \"Policy\" column, select the policy associated with the Category \"Configuration (Client)\" that is specific to the organization and select the \"Throttling\" tab.\n\nVerify the \"Enable Throttling\" check box is selected.\n\nVerify the throttling settings are configured according to organization's written policy.\n\nIf the \"Enable Throttling\" check box is not selected, this is a finding.\n\nIf the throttling settings do not match the organization's written policy or the settings are not documented in the written policy, this is a finding.","fixText":"From the ePO server console System Tree, select the \"Systems\" tab.\n\nSelect \"This Group and All Subgroups\".\nSelect the asset.\nSelect \"Actions\".\nSelect \"Agent\".\nSelect \"Modify Policies on a Single System\".\n\nFrom the product pull-down list, select Solidcore 8.x: General.\n\nFrom the \"Policy\" column, select the policy associated with the Category \"Configuration (Client)\" that is specific to the organization and select the \"Throttling\" tab.\n\nPlace a check in the \"Enable Throttling\" check box.\n\nConfigure the throttling settings based upon organization's written policy.\n\nClick \"Save\".","ccis":["CCI-001774"]},{"vulnId":"V-213347","ruleId":"SV-213347r961479_rule","severity":"medium","ruleTitle":"The Solidcore Client Exception Rules must be documented in the organizations written policy.","description":"When exceptions are created for applications, it results in potential attack vectors.
