Chapter 12 Configuring IP Logging

Understanding IP Logging

Understanding IP Logging

You can manually configure the sensor to capture all IP traffic associated with a host you specify by IP address. You can specify how long you want the IP traffic to be logged, how many packets you want logged, and how many bytes you want logged. The sensor stops logging IP traffic at the first parameter you specify.

You can also have the sensor log IP packets every time a particular signature is fired. You can specify how long you want the sensor to log IP traffic and how many packets and bytes you want logged.

You can copy the IP logs from the sensor and have them analyzed by a tool that can read packet files in a libpcap format, such as Wireshark or TCPDUMP.

Note Each alert references IP logs that are created because of that alert. If multiple alerts create IP logs for the same IP address, only one IP log is created for all the alerts. Each alert references the same IP log. However, the output of the IP log status only shows the event ID of the first alert triggering the IP log.

Note IP logging allows a maximum limit of 20 concurrent IP log files. Once the limit of 20 is reached, you

receive the following message in main.log: Cid/W errWarnIpLogProcessor::addIpLog: Ran out of file descriptors.

Configuring Automatic IP Logging

Use the ip-log-packets number, ip-log-time number, and ip-log-bytes number commands to configure automatic IP logging parameters on the sensor.

The following options apply:

ip-log-packets—Identifies the number of packets you want logged. The valid value is 0 to 65535. The default is 0.

ip-log-time—Identifies the duration you want the sensor to log packets. The valid value is 0 to 65535 minutes. The default is 30 minutes.

ip-log-bytes—Identifies the maximum number of bytes you want logged. The valid value is 0 to 2147483647. The default is 0.

default—Resets the parameters.

Note An automatic IP log continues capturing packets until one of these parameters is reached.

Automatic IP logging is configured on a per signature basis or as an event action override. The following actions trigger automatic IP logging:

log-attacker-packets

log-victim-packets

log-pair-packets

IPS4510K9 specifications

Cisco Systems has long been a leading player in network security, and its IPS (Intrusion Prevention System) series is a testament to its commitment to safeguarding digital environments. Among its notable offerings are the IPS4510K9 and IPS4520K9 models, both designed to provide advanced threat protection for mid-sized to large enterprise networks.

The Cisco IPS4510K9 and IPS4520K9 are distinguished by their cutting-edge features that help organizations defend against a myriad of cyber threats. These systems utilize a multi-layered approach to security, integrating intrusion prevention, advanced malware protection, and comprehensive visibility across the network.

One of the primary characteristics of the IPS4510K9 is its high performance. It boasts a throughput of up to 1 Gbps, making it suitable for environments that demand rapid data processing and real-time responses to threats. The IPS4520K9, on the other hand, enhances that capability with improved throughput of up to 2 Gbps, accommodating larger enterprises with heavier network traffic. These models are equipped with powerful processors that support complex signature matching and can intelligently distinguish between legitimate traffic and potential threats.

In addition to performance, both models are designed with scalability in mind. They can be easily integrated into existing Cisco infrastructures. This facilitates a seamless enhancement of security without causing significant interruptions to ongoing operations. Moreover, they offer flexible deployment options, allowing organizations to operate them inline or out of band depending on their specific needs.

The Cisco IPS4510K9 and IPS4520K9 leverage advanced detection technologies, utilizing a variety of signature types and heuristic analysis to detect known and unknown threats effectively. They are equipped with real-time alerting and reporting capabilities, giving security teams immediate visibility into potential breaches and enabling them to respond swiftly.

Furthermore, both models support a range of management options through the Cisco Security Manager, allowing for centralized administration, streamlined policy management, and enhanced monitoring capabilities. Automated updates ensure the systems remain current with the latest threat intelligence, vital for staying ahead of evolving cyber threats.

In summary, the Cisco Systems IPS4510K9 and IPS4520K9 represent powerful solutions for organizations seeking robust intrusion prevention capabilities. With their high performance, scalability, and advanced detection technologies, these systems are essential tools in the ever-changing landscape of cybersecurity, providing enterprises with the peace of mind needed to operate securely in today's digital world.
