ArcSight is a security management solution designed to track, and compliance policy guidelines components analyze a company product's data insights. It's a portfolio that can operate with various products to address security issues and boost productivity. In this ArcSight tutorial, we covered every element of the ArcSight portal to assist you in obtaining a practical understanding of how to use the ArcSight portal to manage data and its components.
ArcSight is an ESM (Enterprise Security Manager) platform. It is a tool built and applied to manage its security policy. It can detect, analyze, and resolve cyber security threats quickly. The ESM platform has products for event collection, real-time event management, log management, automatic response, and compliance management.
Yes, ArcSight Enterprise Security Manager (ESM), a robust, adaptive SIEM that brings real-time threat detection and native SOAR technology to your SOC, is a SIEM tool that can empower your security operations team.
ESM uses SmartConnectors to collect event data from your network. SmartConnectors convert device event data into a standardized schema that serves as the basis for correlation. In the CORR-Engine, the Manager processes and stores event data. Users can use the ArcSight Console or the ArcSight Command Center to monitor events, run reports, generate resources, conduct investigations, and manage the system. Additional ArcSight solutions that drive event flow, ease event analysis and provide security alerts and incident response are built on ESM's fundamental architecture.
ArcSight is a term used to define the components of a security model, which include features and functionalities for security monitoring. By gathering and preserving data for long-term use cases, ArcSight overcomes the issues of a variety of requirements.
The security and visibility operations that use the monitoring platform architecture are part of the Arcsight SIEM Platform environment. The platform collects, normalizes, and categorizes all network and security device events and logs.
The ArcSight ESM can collect a wide range of log data and combine it with a robust correlation engine to detect threats across various products and notify customers to take action on vulnerabilities.
The ArcSight Logger enables automated compliance reporting and log management and storage. It has a storage capacity of up to 42TB of log data and can search for multiple events per second across organized and unstructured data. It enables SOX, PCI DSS, NERC, and other regulations' automated reporting.
ESM and logger's real-time correlation and log management capabilities are included in the ArcSight Express. The Express contains various built-in correlation rules, dashboards, and reports and is described as a "security expert in a box." It delivers infrastructure setup and monitoring solutions at a minimal cost.
The ArcSight SmartConnectors take event data from network devices and standardize it into a schema. Data can be filtered via connections, saving network bandwidth and storage space. SmartConnectors increases efficiency by grouping events and reducing the number of affairs of the same type. The events may be organized into a legible manner, making it easier to use them to create filters, rules, and reports.
ArcSight ESM version 7.0, ArcSight Express version 5.0, ArcSight Investigate version 2.20, and ArcSight Data Platform version 2.31 (containing ArcSight's Logger, ArcMC, and Event Broker technology) were all launched in January 2019.
The correlation criteria are built using the ArcSight ESM Network model, a network and assert models blend.
The following resources make up the network model's elements.
In ArcSight ESM, there are seven event life cycles.
Data collection and event processing
The information is obtained from a variety of sources and then processed.
Network model lookup and priority evaluation
We use the logical construction of a network with naming and structures to comprehend the environment and location, and then it's time to prioritize.
The correlations will be analyzed in this step, followed by monitoring and investigation.
Monitoring and investigation
The scenarios must be thoroughly understood to know what they are to monitor them, and then an analyst must investigate them before moving on to the workflow.
The workflow process model is implemented in this phase.
Incident analysis and Reporting
Here, we must report the data and analyze what has been gathered or received.
Finally, the events will be archived in an off-site location. The information can be kept for a long time. All seven stages of an event must be completed before an event can be considered complete.
At the SmartConnector level, aggregation limits the number of events consumed by the destination device (ESM / Logger). Suppose a SmartConnector is receiving events from a firewall device, for example. In that case, it will aggregate (i.e., summarize) similar circumstances over a defined period and deliver a single event to the destination. This can save you a lot of money in terms of bandwidth, storage, and processing.
Correlation is a technique for determining the correlations between events. ESM's correlation engine, for example, employs the rules you create (or those provided by ESM) to correlate base and aggregated events coming in from SmartConnectors to identify if something of interest has occurred. For example, a failed login event on an endpoint may not be of interest in and of itself, but if the same failed login event occurs several times in a short period, it could indicate a brute force login attempt. This type of action can be monitored by a rule, which will generate a correlation event that can act.
Below are a few advantages of ArcSight
Below listed are the few disadvantages of ArcSight
The ArcSight tutorial provides a clear picture of using and comprehending compliance policy guidelines components. We hope that the above information gives you a complete understanding of ArcSight.
