Elasticsearch is a search engine based on Apache Lucene, a free and open-source search engine. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents. Official clients are available in Java, [2].NET [3] , PHP, [4] Python, [5] Ruby [6] and many other languages. [7]
The combination of Elasticsearch, Logstash, and Kibana, referred to as the "Elastic Stack" (formerly the "ELK stack"), is available as a product or service. [6] Logstash provides an input stream to Elasticsearch for storage and search, and Kibana accesses the data for visualizations such as dashboards. [ 7 ]
In some related but distinct contexts, the term AAA has been used to refer to protocol-specific information. For example, Diameter uses the URI scheme AAA, which also stands for "Authentication, Authorization and Accounting", as well as the Diameter-based Protocol AAAS, which stands for "Authentication, Authorization and Accounting with Secure Transport". [4]
For instance, for the tls-server-end-point channel binding, it is the server's TLS certificate. [7] An example use case of channel binding with SCRAM as application layer, could be with Transport Layer Security (TLS) as lower layer. TLS protects from passive eavesdropping, as the communication is encrypted.
[2] [3] It was founded in 2012 in Amsterdam, the Netherlands, and was previously known as Elasticsearch. [ 4 ] The company develops the Elastic Stack— Elasticsearch , Kibana , Beats, and Logstash—previously known as the ELK Stack, [ 5 ] free and paid proprietary features (formerly called X-Pack), Elastic Cloud (a family of SaaS offerings ...
For example, to develop a web application, the architect defines the stack as the target operating system, web server, database, and programming language. Another version of a software stack is operating system, middleware , database, and applications. [ 2 ]
Mutual authentication during vehicle communication prevents one vehicle's system from being breached, which can then affect the whole system negatively. For example, a system of drones can be employed for agriculture work and cargo delivery, but if one drone were to be breached, the whole system has the potential to collapse. [2]
The server responds with the 401 "Unauthorized" response code, providing the authentication realm and a randomly generated, single-use value called a nonce. At this point, the browser will present the authentication realm (typically a description of the computer or system being accessed) to the user and prompt for a username and password.
