So ArcSight ESM stands for Enterprise Security Manager.

As the name itself implies the usage of this tool is that it adds value to your organization security policies. Using this tool, it will help the organizations to focus on the threat detection, analysis on the triages, compliance management. All of these are done on SIEM platform where it actually reduces the time taken to resolve a cybersecurity threat.

Q: What does SIEM stand for and what is it about?
SIEM stand for Security Information and Event management.

So this is a platform where a holistic view of the security process implemented within the organization. The letter e is silent and it is addressed as “SIM” platform. Basically, in this process, the data is all gathered into one secure repository where the logs are used for future security analysis. This process is widely used in Payment Card Industry. It is actually classified as a data security standard in Payment Card industry.

Q: What are the key features of ArcSight Enterprise Security Manager?
The key features of ArcSight Enterprise Security Manager is as follows:

1. Enriched Security Event data
2. Powerful real-time data visualization and correlation
3. Automated workflows
4. Security process optimized
5. ArcSight Enterprise Security Manager tool is compatible with ArcSight Data Platform and ArcSight Investigate

Q: Explain how ArcSight ESM is protecting the businesses across the globe?
The following are the different ways that the business is actually protected by using ArcSight ESM tool, as follows:

1. It is capable of collecting data or information from any type of log source
2. It tremendously reduces the response time and also helps in reducing the damage as well
3. It can efficiently store information where the information can be retrieved as we generally do in enterprise-level databases.
4. It provides role relevant reports that are available within the enterprise
5. The architecture is scalable
6. Easily customizable and maintains high-performance system

Q: How does ArcSight ESM provide Powerful real-time data correlation?
Well, ArcSight ESM provides powerful real-time data correlation by processing number of events per second. Based on this analysis a more accurate outcome is proposed. So based on this analysis, the threats that violate the internal rules are escalated within the platform. ESM actually processes 75,000 events per second basis.

Q: What can be done using ArcSight ESM?
ArcSight ESM actually helps the organizations and the individuals as below:

All the event data is collected centrally and stored and monitor
User-friendly compliance reporting in a single touch provides necessary data in an appropriate format.
Has an ability to monitor and mitigate the risk.
Eliminates manual process as much as possible
Saves valuable hours of security analyst where they spend on false alarms
Brings awareness to the team about the security process in place and the countermeasures implemented.

Q: Why do organizations need Security Information and Event Management systems?
Well, most of the small companies don't have enough manpower to make sure that their security process is intact. But they won't be able to be proactive and warn the team that there might be a possible threat attack, this is because they don't have any automatic mechanism which triggers a threat attack. So to solve the real time issue and also make sure the security checks are monitored and analyzed, we have Security Information and Event Management system. Out of this system is ArcSight SEM. So basically all the machine log data is analyzed and understands the patterns of normal behavior vs abnormal behavior.  Thus making it a perfect tool where it can understand the security logs so far and based on the analysis can trigger some information which might prevent a bigger threat to the entire organization.

Q: How can ArcSight ESM help organizations in terms of security aspects?
Well, ArcSight ESM can help the organizations building more enhanced use cases to improve the APT’s ( Advanced Persistent Threats)which will allow a faster and targeted response in a timely fashion.

Q: What are the key capabilities of ArcSight Logger?
The key capabilities of ArcSight Logger is:

1. It collects logs from any sort of log generating source
2. After collecting the data, it categorizes and registers as Common Event Format (CEF)
3. These events can be searched with the use of a simple interface
4. It can handle and store years worth of logs information
5. It is perfect for automation analysis which can be later used for reporting, the intelligence of logs or events for IT Security purposes and logs analytics.

Q: What does ArcSight Connectors mean?
The main use of ArcSight Connectors is listed below:

** With the use of ArcSight connectors, the user can actually automate the process of collecting and managing the logs irrespective of the device. All the data can be normalized into a CEF, i.e. Common Event Format
** ArcSight connectors provide a bunch of universal data collections from different unique devices.

Q: What does ArcSight Manager do, explain in brief?
The use of ArcSight manager is to simply put in place robust security parameters within the organization.So it is one of the high-performance service engines which actually filters, manages, correlates all security-related events that are collected by the IT system.
