ccna 5.0.the number of cart alerts produced l|i:oAs a hybrid between atomic and aggregate alerts, some IPS solutions also allow the generation of individual atomic alerts, but then disable alerts for features initiated from the same source address for a specific period of time. This prevents overwhelmed alerts for administrators, and 11.5.243 Logging this behaviorIn some cases, administrators do not have enough information to stop the system. There is not always enough information to stop. In some cases, the administrator does not necessarily have enough information to stop a behavior. Therefore, it is important to record the behavior or packets seen first for subsequent detailed analysis. IPS can log attacker packets, pairpackets, or just victim packets.By performing a detailed analysis, administrators can identify exactly what is being sent, and II. decide whether to... Whether to allow or disallow.For example, if the administrator has configured... T./etc/password, and whenever the feature is triggered, it logs the behavior of the attacker's IP address, the IPS device begins to record the data stream for a specified period of time or a specified number of bytes from the attacker's IP address. This information is usually stored in a special file on the IPS device I:. Because features also generate alerts, administrators can observe these alerts on the management console. Later these 11 log data can be found from IPS device L, and the actions performed by the attacker on the network can be analyzed after the initial alert is triggered.5.2.4.4 Discard or block this behaviorOne of the most powerful behaviors that an IPS device can perform is to drop packets or block This behavior can occur. An IPS can deny attacker packets, denydeny connections, or deny specific packets. The act of dropping a packet stops the device before the attacker has a chance to perform a malicious act. Unlike traditional IDS devices, IPS devices actively forward packets between two interfaces. The analysis engine determines which packets should be forwarded and which packets should be discarded.In addition to dropping individual packets, the dropping behavior can be extended to dropping all packets for a specific session, or even all packets from a specific host within a certain time frame. By dropping traffic from a single connection or host, the IPS retains resources without having to analyze each packet individually.
