Current release of Search Guard with new standard "Signals" functionBerlin, 23.07.2020. With the current release version 7.x-42.0.0, Search Guard provides the new standard function "Signals". The alerting and monitoring feature helps IT administrators detect deviations and conspicuous changes in data stored in Elasticsearch clusters. This can be customer or payment data, production values, key figures for the company and much more. Search Guard is an independent open source plug-in for the protection of Elasticsearch clusters. The alerting feature is now standard and it is available for free in the Community Edition.
Attacks and data theft are often preceded by undiscovered abnormalities in a data cluster which may come from multiple failed online payment, fraudulent financial transactions or frequent incorrect password entries. The more sensitive the data stored in the cluster, the more important it is to quickly detect abnormalities and prioritize them correctly. To do this, IT management needs an alerting strategy. Alerting management is not only useful in cases of fraud, but also in price-sensitive industries that are subject to high dynamics due to currency fluctuations, such as securities trading or airline tickets.
Remain capable of acting at all timesWith the new Signals feature in Search Guard, IT administrators can implement an alerting strategy that delivers warning signals to various notification channels based on a multi-level escalation model. This ensures that IT departments remain capable of action both in the operational business and in the event of an attack. Signals controls monitoring and notification management in the event of data abnormalities in Elasticsearch clusters. The feature can be combined with all common IT systems that have a REST interface. Thus Signals is also used for monitoring the entire IT infrastructure.
The core of Signals from the administrator's point of view is the graphical user interface. This allows all settings to be made intuitively and user-friendly without additional programming effort. Different severity levels are defined via the user interface, as well as the notification channels and notification rules.
"To provide IT administrators with even better protection for their cluster and to offer high added value, we have expanded Search Guard to include the Alerting Feature Signals," says Jochen Kressin, Managing Director of floragunn GmbH, the manufacturer of Search Guard. "Signals enable the right people to know what to do at the right time and can take action".
Signals at a glance
Multiple sources of data inputThe most important data source that Signals can access is Elasticsearch in version 7.4.0 and higher. In addition, data from other endpoints can also be processed, which significantly expands the scope of application for IT administrators. Signals ships with an HTTP adapter so that data from any HTTP REST endpoint can be included. Signals also supports authentication (HTTP Basic, JWT and client certificates) and TLS.
Dynamic conditions and severity levelsSignals provides alerting both commonly on severity and with fully dynamic conditions to trigger alerts. Dynamic conditions are available, for example, if you want to monitor data that is fed from different data sources.
Versatile output channels for notificationsOutput channels for alerting notifications are currently e-mail, Slack, Webhooks, PagerDuty and JIRA. Support for Microsoft Teams as an output channel is planned. Depending on the severity, it is possible to define which alert is sent to which recipient via which channel. The number of notifications can be controlled and for example reduced to one notification per defined interval. It is also possible to set the alerts at preset times, for example every 30min or exponentially after two minutes, four minutes and so on.
OutlookSignals is available for free in the Community Edition and can be installed and tested without any effort. Instructions and downloads for developers can be found in the documentation. All questions and requests around the feature are answered in Signals Community Forum.
