Understanding HCP Terminology
This section defines the key terminology associated with cybersecurity, Hadoop, and HCP:
- Alert
Alerts provide information about currently security issues, vulnerabilities, and exploits.
- Apache Kafka
Apache Kafka is a fast, scalable, durable, fault-tolerant publish-subscribe messaging system, that can be used for stream processing, messaging, website activity tracking, metrics collection and monitoring, log aggregation, and event sourcing.
- Apache Storm
Apache Storm enables data-driven, automated activity by providing a real-time, scalable, fault-tolerant, highly available, distributed solution for streaming data.
- Apache ZooKeeper
Apache ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services.
- Cybersecurity
The protection of information systems from theft or damage to the hardware, software, and to the information on them, as well as from disruption or misdirection of the services they provide.
- Data management
A set of data management utilities aimed at getting data into HBase in a format which will allow data flowing through metron to be enriched with the results. Contains integrations with threat intelligence feeds exposed via TAXII as well as simple flat file structures.
- Enrichment data source
A data source containing additional information about telemetry ingested by HCP.
- Enrichment bolt
The storm bolt that applies the enrichment to the telemetry.
- Enrichment data loader
A streaming or a batch loader that stages the data from the enrichment source into HCP so that telemetry can be enriched in real-time with the information from the enrichment source
- Forensic Investigator
Collects evidence on breach and attack incidents and prepares legal responses to breaches.
- Model as a Service
A Yarn application which can deploy machine learning and statistical models onto the cluster along with the associated Stellar functions to be able to call out to them in a scalable manner.
- Parser
A storm bolt that transforms telemetry from its native format to a JSON that Metron is able to understand.
- Profiler
A feature extraction mechanism that can generate a profile describing the behavior of an entity. An entity might be a server, user, subnet or application. Once a profile has been generated defining what normal behavior looks-like, models can be built that identify anomalous behavior.
- Security Data Scientist
Works with security data, performing data munging, visualization, plotting, exploration, feature engineering, model creation. Evaluates and monitors the correctness and currency of existing models
- Security Operations Center (SOC)
A centralized unit that deals with cybersecurity issues for an organization by monitoring, assessing, and defending against cybersecurity attacks.
- Security Platform Engineer
Installs, configures, and maintains security tools. Performs capacity planning and upgrades. Establishes best practices and reference architecture with respect to provisioning, managing, and using the security tools. Maintains the probes to collect data, load enrichment data, and manage threat feeds.
- SOC Analyst
Responsible for monitoring security information and event management (SIEM) tools; searching for and investigating breaches and malware, and reviewing alerts; escalating alerts when appropriate; and following security playbooks.
- SOC Investigator
Responsible for investigating more complicated or escalated alerts and breaches, such as Advanced Persistent Threats (APT). Hunts for malware attacks. Removes or quarantines the malware, breach, or infected system.
- Stellar
A custom data transformation language that is used throughout HCP from simple field transformation to expressing triage rules.
- Telemetry data source
The source of telemetry data which can vary in level from low level (packet capture), intermediate level (deep packet analysis) or very high level (application logs).
- Telemetry event
A single event in a stream of telemetry data. This can vary in level from low level (packet capture), intermediate level (deep packet analysis) or very high level (application logs).
