Apache Kafka
Apache Kafka is a distributed event streaming platform that allows for the building of real-time data pipelines and streaming applications. It is designed to handle high throughput and low latency, making it suitable for large-scale data processing. Kafka is often used for log aggregation, stream processing, and real-time analytics.
What is Apache Kafka
Apache Kafka is an open-source distributed event streaming platform developed by the Apache Software Foundation. It was originally developed by LinkedIn and later open-sourced in 2011. Kafka is designed to handle high throughput and low latency, making it ideal for real-time data processing and analytics.
Kafka's architecture is based on a distributed commit log, allowing it to store streams of records in a fault-tolerant manner. It supports both publish-subscribe and queue-based messaging models, making it versatile for various use cases. Kafka is commonly used for log aggregation, stream processing, and building real-time data pipelines.
Kafka's ecosystem includes several components such as Kafka Connect for integrating with external systems, Kafka Streams for stream processing, and Kafka's REST Proxy for HTTP-based communication. Its scalability and reliability have made it a popular choice for companies looking to process large volumes of data in real-time.
Security risk
If port 9092 is open and the Kafka service is running, it could be exposed to unauthorized access and potential data breaches. Attackers could exploit vulnerabilities in Kafka to intercept or manipulate data streams, leading to data loss or corruption. It is crucial to secure Kafka with proper authentication and encryption mechanisms to mitigate these risks.
In our UFW tutorial you can follow instructions how you can configure UFW to close port 9092. Use StackChanges to monitor if the Apache Kafka port is closed and stays closed. StackChanges will send an alert if port 9092 is open again.
