Encrypting IDF Server to DB Communication Communication between the IDF Server Plug-in and the database is not encrypted by default. This is for performance reasons and because the channel between the Server Plug-in and the database may already be secure (either they are running on the same Computer or they are connected by crossover cable, a private network segment, or tunneling via IPSec). However, if the communication channel between the IDF Server Plug-in and the database is not secure, you should encrypt the communications between them. Do this by editing the dsm.properties file located in \IDF Server Plug-in\webclient\webapps\ROOT\WEB-INF\ MS SQL Server Add the following line to dsm.properties: database.SqlServer.ssl=require Save and close the file. Stop and restart the Server Plug-in service. Oracle Database Add the following lines to dsm.properties: database.Oracle.oracle.net.encryption_types_client=(3DES168) database.Oracle.oracle.net.encryption_client=REQUIRED database.Oracle.oracle.net.crypto_checksum_types_client=(MD5) database.Oracle.oracle.net.crypto_checksum_client=REQUIRED Save and close the file. Stop and restart the IDF Server Plug-in service. Note that Oracle Database must be configured to accept encrypted communication. Consult your Oracle Database documentation for instructions. Running a Client Plug-in on the Database Server Encryption should be enabled if you are using a Client Plug-in to protect the database. When you carry out a Security Update, the IDF Server Plug-in stores new DPI Rules in the database. The rule names themselves will almost certainly generate false positives as they get parsed by the Client Plug-in if the data is not encrypted. © Copyright 2010 Trend Micro Inc. www.trendmicro.com All rights reserved. - 136 -
Firewall Events CE Flags Event Notes Dropped Retransmit Dropped Retransmit. First Fragment Too Small Fragment Offset Too Small Fragment Out Of Bounds Fragmented Internal Driver Error Insufficient resources. The CWR or ECE flags were set and the stateful configuration specifies that these packets should be denied. A fragmented packet was encountered, the size of the fragment was less than the size of a TCP packet (no data). The offsets(s) specified in a fragmented packet sequence is less than the size of a valid datagram. The offsets(s) specified in a fragmented packet sequence is outside the range of the maximum size of a datagram. A fragmented packet was encountered with deny fragmented packets disallowed enabled. Internal States Error Internal TCP stateful error. Invalid ACK A packet with an invalid acknowledgement number was encountered. Invalid Adapter Configuration An invalid adapter configuration has been received. Invalid Data Offset Invalid data offset parameter. Invalid Flags A packet with nonsensical flag combinations was encountered. Invalid IP Packet's source IP was not valid. Invalid IP Datagram Length Invalid Port Command Invalid Sequence Invalid IP Header Length The length of the IP datagram is less than the length specified in the IP header. An invalid FTP port command was encountered in the FTP control channel data stream. A packet with an invalid sequence number or out-of-window data size was encountered. An invalid IP header length (< 5*4 = 20) was set in the IP header. IP Version Unknown An IP packet other than IPv4 or IPv6 was encountered. IPv6 Packet Max Incoming Connections Max Outgoing Connections Max SYN Sent Maximum ACK Retransmit Null IP Out Of Allowed Policy An IPv6 Packet was encountered, and IPv6 blocking is enabled. The number of incoming connections has exceeded the maximum number of connections allowed. The number of outgoing connections has exceeded the maximum number of connections allowed. The number of half open connections from a single Computer exceeds that specified in the stateful configuration. This retransmitted ACK packet exceeds the ACK storm protection threshold. a NULL (0.0.0.0) IP is not allowed by the present firewall configuration The packet does not meet any of the Allow or Force Allow rules and so is implicitly denied. © Copyright 2010 Trend Micro Inc. www.trendmicro.com All rights reserved. - 137 -
