Amazon GuardDuty vs Nagios: What are the differences?
Developers describe Amazon GuardDuty as "Continuous Security Monitoring and Threat Detection". It is a managed threat detection service that continuously monitors for malicious or unauthorized behavior to help you protect your AWS accounts and workloads. It monitors for activity such as unusual API calls or potentially unauthorized deployments that indicate a possible account compromise. It also detects potentially compromised instances or reconnaissance by attackers. On the other hand, Nagios is detailed as "Complete monitoring and alerting for servers, switches, applications, and services". Nagios is a host/service/network monitoring program written in C and released under the GNU General Public License.
Amazon GuardDuty and Nagios can be categorized as "Monitoring" tools.
Some of the features offered by Amazon GuardDuty are:
- Accurate, account-level threat detection
- Continuous monitoring across AWS accounts without added cost and complexity
- Threat detections developed and optimized for the cloud
On the other hand, Nagios provides the following key features:
- Monitor your entire IT infrastructure
- Spot problems before they occur
- Know immediately when problems arise
Nagios is an open source tool with 60 GitHub stars and 36 GitHub forks. Here's a link to Nagios's open source repository on GitHub.
- free open source
- modern interface and architecture
- large community
- extendable I knew Nagios for decades but it was really outdated (by its architecture) at some point. That's why Icinga started first as a fork, not with Icinga2 it is completely built from scratch but backward-compatible with Nagios plugins. Now it has reached a state with which I am confident.
