AD7820BQ Article About

Finally, the attackers IP header field is used DF, this bit indicates if the IP packet exceeds the maximum allowed length of the forwarding device, whether it can be divided into pieces. If the IP packets DF flag is set to 1, that means this group can not be fragmented, when it exceeds the maximum allowed transfer device length, will be discarded. Therefore, if the NIDS allow maximum data packet length greater than the monitoring system, we can make a packet containing information on the size of garbage in between, resulting in IDS to insert spam. These techniques seem easy in principle, but in practical application process, the need to target networks and systems have a very deep understanding of the situation to be implemented, otherwise, very small chance of success:). Checksum error problem difficult to solve, as long as the IDS packet of error checking and other systems using the same approach to it. IP packet options field can also be used to IDS attacker to insert spam. For the IP options, the treatment of various systems vary widely, so it is easy to trick an attacker to succeed.
