Matthew Hoerig - PeerSpot reviewer
Audit function refines log retrieval and drives application assessments with evolving features
From a service assessment and authorization process perspective, when conducting an assessment on an application or system, we use controls essentially equivalent to the NIST 800-53 framework. This includes examining audit logs, data quality, and various KPIs required for log configuration. It factors into our application assessments. When producing documentation packages for application or system authorization, audit logging and monitoring are crucial parts of the assessment process. The evidence we gather includes screenshots and outputs from these tools and capabilities. For Microsoft Purview Audit specifically, we provide examples of audit function configuration and log output details, which are incorporated into our evidence documents.

Built-in searches and unified data access streamline alert investigation and boosts analyst efficiency
The two features I appreciate the most in Splunk Enterprise Security are the built-in searches, which have been very easy for us to get started with right out of the box, and the fact that it accesses all of our other systems. You can access it as a pane of glass rather than having to search individually. We also have the option to compare our analysts from our service to service. Splunk Enterprise Security helps our SOC team prioritize and investigate high-fidelity alerts more effectively by providing a more in-depth look and the ability to access a lot more of our data. Instead of jumping from several segmented systems, it allows us to have everything brought together in one place. For example, you have to move from our purview to our build system and to Splunk Enterprise Security, and it enables us to streamline that process. The built-in features of Splunk Enterprise Security, which we recently procured, have given us a good starting point and demonstrated the value of the product, providing an easy way to sell it to our company. The ease of getting everything into our purview helps us, and it serves as a good start for the investigation part in one location rather than what we usually have, which is jumping from system to system to system. Splunk Enterprise Security plays a role in our company's strategy to combat insider threats and advanced persistent threats by currently being in its technical test phase. We are still rolling it out, and it should help us find any insider threats based on information that our policy states should not be present in our system. Splunk Enterprise Security's risk-based alerting (RBA) has impacted our alert volume and analyst productivity because we've got many different systems feeding into it. However, it has helped to make it easier for our analysts to go through a set of events rather than 100 alerts. RBA allows us to streamline the process and customize it for our analysts. When it comes to leveraging Splunk Enterprise Security's dashboards and visualizations to communicate security posture to executives, it's pretty straightforward for any type of information. The visualization is easy to understand, but I haven't had any direct conversations with our executives.

Cons

"We do have a Denial of Access happening."
"We are still in the early stages of leveraging Microsoft Purview Audit. Currently, it's primarily used for the audit function."
"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
"The incident response dashboard could be more user-friendly."
"The solution's automation could be improved."
"I think the machine learning should be emphasized. Now, it's really important to analyze Big Data, data mining. A SIEM solution, like Splunk, needs an improved data mining solution, artificial intelligence."
"There are a lot of competitive products that are doing better than what Splunk is doing on the analytics side."
"If possible, we would like to have not only a log monitoring system but a network monitoring feature in this solution as well."
"The system can be intimidating, and sometimes the concepts conveyed in the documentation require adjustment."
"Sometimes the communication with support happens with multiple staff. They should reduce the time to resolution."
"Splunk is query-based, which is not the case with most cybersecurity tools. It is based on search queries and can be difficult to use. It would be good if they can make it easier to understand how to create search queries. They can improve the knowledge base for better understanding. To create your dashboard, you need to have a search query. We have multiple firewalls in our company, and we need a dashboard for them. It would be helpful if a default firewall dashboard is included in Splunk to make monitoring easier. If a dashboard is available for a security device, the operation part will be more efficient. We won't have to follow a manual process for this."
