Cybersecurity management can include preventative, reactive, and proactive strategy. Nagios Log Server is an excellent resource for each strategy as its ease of use combined with powerful performance allows organizations to focus on managing security insight rather than maintaining a reactive state. Nagios Log Server is flexible enough to accept any log data from any device capable of sending it. This includes devices like routers and switches, Internet of Things (IoT), servers, and workstations. This log data can then be filtered and introduced into various visual dashboards in addition to being able to alert appropriate staff in real-time.

The ability to audit, report, alert, and store massive amounts of granular log data is important for any business, which is why it is a popular solution for business who abide by strict compliance regulations. Reporting and alerting Is important for access systems, application servers, financial transaction and gateway data, and many other sources of potential liability or vulnerability. Accurate reports and easy export options allow for an audit trail to be produced in just moments. User activity logs on a specific workstation, for example, can be narrowed and filtered from all logs to display data relevant to access and permission attempts.


Real-time alerting based on specific log data is an important step in identifying potential security vulnerabilities and attacks. Nagios Log Server allows administrators the ability to be immediately notified about log data that requires rapid response. Nagios Log Server can be easily integrated into Nagios XI where security teams can configure actionable scripts called “event handlers” to perform actions based on log data received. For example, a series of malicious login attempts to a server can trigger an alert as well as an event handler in Nagios XI to stop a running service for a predetermined amount of time.


The easy to use interface of Nagios Log Server allows administrators to customize and display various dashboards where log data can be displayed in easier to understand formats. Instituting filters and being able to focus on specific metrics inside particularly long strings of data is what makes Nagios Log Server so successful at pinpointing troubles before they result in downtime or security vulnerabilities.

Nagios Log Server was built to accommodate data retention and fail-over strategies. There are many flexible ways to deploy Nagios Log Server including a cluster, where fail-over protection and redundancy is just one of many benefits. A cluster also gives Nagios Log Server a performance increase by allowing massive amounts of log data to be written and organized safely between all connected instances. Automatic backups, redundancy and replica checks, and other protections keep log data safe and secure.
