BNY Mellon, Walt Disney Company, The TJX companies, and others are a few of the big companies that use Splunk Enterprise Security. Splunk Enterprise Security helps the security personnel to find out security-related threats that are usually found in enterprise infrastructure. It is built on the operational intelligence platform of Splunk. It facilitates users to monitor, capture and also report data from applications, systems, and all security devices. Once the user discovers the security threats, it becomes easy for the security analyst to understand, investigate and resolve the danger across all the access, endpoint, and network domains. In a nutshell, Splunk ES (Enterprise security) provides its users with an end-to-end view of their organization's security postures.
Splunk (ES) Enterprise Security is modern security, data-centric, and event management solution that provides data-driven information into an organization's security posture to protect and mitigate risk. Integrated intelligence, searching and reporting, Analytics, and prepacked security content. Splunk ES helps businesses to detect threats.

Spunk ES helps you in the following:
Splunk Enterprise Security provides you analytics so that the organization can protect business, mitigate risk, and combat threats. It helps the users with complete visibility and detects threats in the environment. It is built on an open and scalable platform. Spunk can be integrated across all data, content, and tools. The Splunk enterprise security helps in continuous monitoring, running a security center of operations, incident response, and providing security personnel with a snapshot of the business risks. It helps businesses with the following:
To get a clear blueprint of the organization's security position the user needs to continuously monitor. This can be done by using an extensive set of trending indicators, custom views with performance metrics and key security metrics, and static, predetermined dashboards. The user can reduce the organization's risk by detecting new and continuing threats so that the incident response can be accelerated.
The user needs to reduce all the false positives in the system, more sophisticated threats need to be detected, and Align all the security operations to MITRE ATT &CK (industry frameworks) with RBA ( Risk-Based Alerting). The user will have to improve incident response workflows using prioritized alerts, centralized logs, UBA anomalies, reports, and correlations that are pre-defined. Organize and streamline investigations and fasten the incident response by using an investigation workbench so that one or more events in a view can be investigated.
To determine any malicious activity using visual correlations, static and dynamic, ad-hoc searches, conduct rapid investigation. To develop threat context and also track the attacker's steps so that evidence can be verified the user will have to pivot from the data and investigate. Find any additional information and also collaborate with all the team members.
Perform breaches and investigate to discover the activities that are associated with compromised systems. In combination with the investigation timeline and investigation journal, the user can use Splunk Enterprise Security and ad hoc searches to gaze at the attack lifecycle by applying the kill-chain method.

The security dashboard provides high-quality insights into significant events covering all domains of deployment, idle for display in SOC
(Security Operation Center). The dashboard displays all the events and trends in the past 24 hours and also provides the organization with real-time updates and information on the events.
Security posture refers to an enterprise's status of networks, systems, and information security resources such as policies, software, hardware, and its capabilities to tackle the defense of the organization and react to the changes in the situation. The user can easily create on their own or can arrange a library of all the security posture tools to place on any of the dashboards. The key performance indicators provide monitoring and trending of the security postures.
Current status of all the notable events is displayed with the help of the Incident Review Dashboard. The user can filter the notable events based on the specific fields. Investigation workflow can also accelerate the order of the notable events. An analyst can use the dashboard to gain deep insights into the gravity of events that will occur in the system or the network.
The Risk Analysis dashboard provides the users with the ability to recognize actions that increase the risk profile of any individual or asset. The dashboard allows the user to identify people or devices that are performing unfamiliar risky activities.
The user activity dashboard presents panels indicating risk-generating activities of users, for instance, suspicious activity of the website. The user activity dashboard helps the analyst review activity of the users in the system within the stated period. The user dashboard can help in drilling down into the activities of the specific user.
It simplifies access to control monitoring, exceptional analysis, and the audit process for applications. Systems used for operational purposes and identity management systems across the enterprise. Satisfy the compliance and requirements of forensics to track high privileged users and system access endeavors on any business-critical application.

The user can use the UBA Anomalies dashboard to get an idea of all the anomalies and threats that UBA discovers in the environment. Understanding anomalies and threats are vital as they relate to other metrics. Though, there are limits to the overall number of anomalies and threats that a UBA can process. The user must maintain the Splunk DBA deployment in the system by managing all the number of anomalies and threats.
The Asset investigator dashboard aggregates all the security-related threats visually over a while by using swim lanes that are category defined. Every swim lanes indicate either a malware, event category, or all the notable events. A heat map is used by the swim lane to indicate periods of high and low activity. The event density of the swim lane corresponds to the color saturation for a particular time. For instance, high activity is indicated by a dark color. A user can ideally have a visual presentation by linking the activities across all the event categories and then form a complete view of the user’s interaction in the environment.
The endpoint domain includes reports, a plethora of alerts, and searches for malware, resource utilization, rare activities, and availability. For endpoint protection, the user needs to increase the effectiveness of the endpoint security.
An analyst needs to detect by monitoring events from the network and also the security devices. Find anomalies across DHCP, load balancers, wireless access points, intrusion, routers, and devices that prevent data loss. Capabilities include searches, correlations, reports, and dashboards for monitoring, reporting, and also alerting on network-based events. To understand behavioral outliers is employed which are HTTP based on statistical analysis.
Breach investigation, scoping and incident investigation, by leveraging the threat feet from a large set of resources including a feed on basis of subscription in the structure of the TCP streaming, law enforcement feeds, Manual downloads that can be in a form of the local environment. The user can weigh the feed based on the relative value which is collected automatically along with de-duplicate and aggregated.
