Info

Deep Packet Inspection Deep Packet Inspection Turn DPI on or off and set the Inline DPI behavior to "Prevent" or "Detect". When first applying a new set of DPI Rules you can choose to set the DPI behavior to "Detect". When in Detect mode, the DPI engine will apply all the same DPI Rules to traffic but instead of dropping packets, it will only log an Event and let the traffic pass. Use this behavior to ensure the new DPI Rules will not interfere with legitimate traffic. This setting only applies when the Network Engine is operating Inline; that is, live traffic is being streamed through the IDF network engine. The alternative to Inline mode is Tap mode, where the live traffic is cloned, and it is only this cloned traffic that is analyzed by the network engine. Prevent mode is impossible when in Tap mode because the network engine does not control the live traffic stream. To switch between Inline and Tap mode, go to System > System Settings > Firewall and DPI. Recommendations Client Plug-ins can be configured to perform regular Recommendation Scans which scan a Computer and make recommendations about the application of various Security Rules. Selecting this checkbox will automatically assign recommended rules to the Computer and automatically unassign rules that are not required. To turn the recommendation engine on or off, go to System > System Settings > Scan. © Copyright 2010 Trend Micro Inc. www.trendmicro.com All rights reserved. - 38 -
DPI Events By default, the IDF Server Plug-in collects Firewall and DPI Event logs from the IDF Client Plug-ins at every heartbeat. (This can be turned off from the Firewall and DPI tab on the System > System Settings screen.) The data from the logs is used to populate the various reports, graphs, and charts in the IDF Server Plug-in. Once collected by the IDF Server Plug-in, Event logs are kept for a period of time which can be set from System tab on the System > System Settings screen. The default setting is one week. From the main screen you can: View ( ) the properties of a particular event Filter the list: Use the Period and Computer toolbars to filter the list of events Export ( ) the event log data to a CSV file Search ( ) for a particular event Additionally, right-clicking a log entry gives you the option to: Computer Details: View the Details screen of the Computer that generated the log entry DPI Rule Properties: View the all the properties of a particular log entry on open Properties window Whois Source IP: Perform a whois on the source IP Whois Destination IP: Perform a whois on the destination IP Columns for the DPI Events display: Time: Time the event took place on the Computer. Computer: The Computer on which this event was logged. (If the Computer has been removed, this entry will read "Unknown Computer".) Reason: The DPI Rule associated with this event. Application Type: The Application Type associated with the the DPI Rule which caused this event." Action: What action the DPI Rule took (Allow, Deny, Force Allow, Log Only, or Detect Only (if the rule is in Detect Only mode)). Rank: The Ranking system provides a way to quantify the importance of DPI and Firewall Events. By assigning "asset values" to Computers, and assigning "severity values" to DPI Rules and Firewall Rules, the importance ("Rank") of an Event is calculated by multiplying the two values together. This allows you to sort Events by Rank when viewing DPI or Firewall Events. Direction: The direction of the packet (incoming or outgoing) Interface: The MAC address of the interface through which the packet was passing. Protocol: Possible values are "ICMP", "IGMP", "GGP", "TCP", "PUP", "UDP", "IDP", "ND", "RAW", "TCP+UDP", AND "Other: nnn" where nnn represents a three digit decimal value. Flags: Flags set in the packet. Source IP: The packet's source IP. Source MAC: The packet's source MAC address. Source Port: The packet's source port. Destination IP: The packet's destination IP address. Destination MAC: The packet's destination MAC address. Destination Port: The packet's destination port. Packet Size: The size of the packet in bytes. © Copyright 2010 Trend Micro Inc. www.trendmicro.com All rights reserved. - 39 -
