If you have a network firewall on your network, you can set up a rate limit on IP address for logging. However, there are some risks associated with logging IP addresses. In particular, IP address logging can lead to DDoS attacks. In this article, we’ll cover how to configure the rate limit and how to perform data analytics on your IP address for logging.
Configuring IP address for logging
The first step in configuring IP address for logging is to configure the DNS server. This is important, because DNS is necessary to make the log server available. In addition, configure the Log Server IP address and port number. After the server is configured, you need to change the database connection for all the reporting tools.
The next step in configuring IP address for logging is to configure the Default Outgoing Interface policy. This policy is used by the syslog server to log information. During the IP address allocation process, the logging feature can be used to monitor address allocation and fault location. In addition, the logging feature can be used to show logs when an address lease is successfully renewed or expired, or when a conflicting address is reclaimed.
The IP address used for logging can be configured to be the primary or secondary Platform System Manager. If the remote host uses TCP, the logging messages are sent to it via UDP. There is no command to disable the 192.168.0.1 logging protocol on a primary Platform System Manager. To reset the remote log port, use the iplog-status command.
Configuring rate limit for network firewall log messages
You can configure a rate limit on network firewall log messages to prevent the firewall from logging too many messages. This setting determines the maximum number of log messages the firewall will log per second. By default, the firewall will not log any messages if the rate limit is exceeded. You can enable logging for IP error packets, TCP errors, and TCP session open and close events.
There are two types of rate limits: rate limit all and rate limit icmp. Both rate-limit all and rate-limit icmp can be configured on the same interface. The latter is more commonly used. The rates of each type are also different. You must specify the condition before enabling a rate limit.
Rate limiting is useful for limiting the effect of TCP SYN flood attacks on your network. For instance, if the hacker has a source IP address of 201.1.1.1, rate-limit will limit the amount of data allowed per TCP SYN.
Data analytics on IP address for logging
As a response to privacy concerns, Google Analytics has banned the logging of IP addresses. The move is seen as a strategic move by the search engine giant in response to the backlash in Europe over the practice. The Austrian Data Protection Authority had cited failure to implement IP anonymization as one of the reasons for banning the practice. While the move may seem premature, experts say it is a timely step to protect user privacy.
One common use for IP addresses in logging is security logging. It allows entities to identify the source and pattern of attacks and to prevent them from occurring. This data can also help organizations prevent future attacks by providing an early warning of possible attacks.
