SIEM Arcsight overview

Arcsight is an enterprise security manager or ESM, that consists of ingestion and interpretations of systems loggings, establishing connections to threat feeds, real-time device correlation, data analytics, alerting security, and user data presentation through UI (user interface) dashboards and data reporting. ESM also supports baselining and mechanism notification, this can be achieved through the integration with various analytical products like Arcsight user behavior analytics or UBA. Arcsight also includes the data enrichment features like data assessment, network modeling, geo-location, user modeling, and vulnerability.

Why SIEM ArcSight:

Below are the key reasons which will explain why we need SIEM ArcSight:

1. SIEM ArcSight supports the big data Hadoop features and helps to collect the events and perform data analysis.

2. SIEM ArcSight makes use of machine learning language to assist various event management tasks.

3. Easy integration with third-party users and external users to threat risk management services.

4. This tool also helps to manage the active directory objects and properties. Also helps to manage the active directory permissions.

5. Manage the target system permission and offers massive configurations and customization capabilities.

6. Secured connectivity with people, things, and devices. This tool also offers configuration assessment to different system properties.

7. SIEM ArcSight is also a cyber security tool that helps users to protect devices from threats and licensing protection.

  • Real-world & Project Based Learning

SIEM ArcSight is a high availability security system design and associates with various service implementations that ensure high level operational performance. The default components included are communications, cache, commit, recovery, and hardware components. Firstly analysts will leverage the Arcsight console or a web browser to access ESM, Logger, and CA. Here the enriched events from ESM will be forwarded to the logger for long term event storage. Then events from all smart connectors will be forwarded to the ESM instances. All smart connectors are managed remotely via the ArcSight connector appliances or ESM manager. After that events of interest will be forwarded from logger to ESM for real-time correlation. Correlated events will be forwarded back to the logger for long term storage. Events from all smart connectors will be forwarded to separate loggers for load balancing purposes. All smart connectors are managed remotely via the Arcsight connector appliance.

Components of ArcSight:

The following are the major components of Arcsight:

1. Smart connector:

The main functions included are:

  a. Helps to collect all the required event logs from the network devices.

  b. Filters data enables you to save storage and bandwidth.

 c. Helps to parse all the events and normalize the common schema.

d. This even aggregates the events to reduce the event count.

 e. Categorize the events in a common format in order to establish rules and filters.

2. ArcSight manager:

The common functions included are:

a. This is a java server-based component.

b. Evaluates the events as per network model and information vulnerability.

c. Helps to develop real-time threat summaries.

d. Writes events to CORR event engine.

3. CORR event engine or Correlation optimized retention and retrieval engine:

The main functions included are:

a. Here ESM helps to organize the data and stores them in the corr engine as per the required event retention period.

b. Even correlation of events take place in the corr engine and archived for long-term use.

User Interface components of ArcSight:

1. Arcsight command center:

a. Helps to manage users, event data, and storage.

b. Helps to monitor the events.

c. Generate reports and updates the license.

2. Arcsight console:

a. Build the filters, reports, patterns, discovery, rules, and dashboards.

b. Helps to monitor the data.

c. Administer the users and workflows.

3. ArcSight web:

a. This is a web interface manager and helps to monitor the events.

b. Mainly used to drill down the dashboards, reporting, and security analyst notifications.

4. ArcSight risk insight:

a. helps to assess the business impact this is due to specific threats to define the rules.

5. Pattern discovery:

a. This is used to detect various data patterns of any event flow and purposes include are:

1. Discover zero attacks

   2. Discover low and slow attacks

   3. Discover profile common patterns in networking

   4. Helps to automatically security rules.

SIEM Arcsight features

Below are the latest features of SIEM ArcSight:

1. Threat blocked:

This is one of the important features of security management. It includes the data access to the ArcSight threat framework and also helps to market the contents for the latest current security products like rules, reports, use cases, and dashboards.

2. Source ingestion:

The latest and most important feature of the SIEM ArcSight tool and helps to analyze the data from various devices and also incorporates the cyber threat data intelligence through STIX and CIF standard dashboards. Source ingestion consists of smart connectors that support event format, APIs, logs, flat files, firewall logs, Net flow, XML/JSON, and database connectivity.

3. High-level Performance:

 This feature also offers 100,000 events per second or EPS.

4. Value:

With the help of this feature, users can convert from legacy licensing data models to the new or latest release, and the ADP of any architecture reports the issues to manage conversion complexity and costs. To perform this Microfocus has implemented the changes to licensing format that includes pricing options to restrict the free data access.

5. Implementation:

This is also the latest feature; here the users generally report easy implementation. As per the Gartner report, ArcSight is an extensively customized tool to support threat management and compliance use cases. ArcSight API enables extensive data integration in multiple SOC environments.

6. Management:

This is the popular and best feature of the ArcSight tool. With the help of this feature data modular packages help to allow various custom rules, other contents, and SIEM dashboards will be exported and this will be shared across customers, devices, and systems. This feature also includes centralized management, reporting the enterprise security events, and data analysis.

7. Supporting:

Here users can generally note solid data management and security support, but it may cost you.

8. Scalability:

This is also a very important feature; you can scale up to 100,000 EPS along with distributed correlation.
