They generate user activity logs-which describe what users did in which applications, dialog boxes, console commands, webpages, etc.-as well as video recordings of the screens seen by users. User activity logs, which are generated by User Activity Monitoring systems, focus on the actual activity of users (administrators, business users, remote vendors, etc.) within applications, websites, operating system areas and network device configuration interfaces. Improving SIEM with User Activity Logs and Session Recordingsįortunately, there is a straightforward and easy-to-implement solution that addresses the abovementioned limitations: adding user activity logs to the data processed by SIEMs, as well as linked screen video recordings of all user activity. User activity within legacy, cloud, system and consumer-oriented applications are examples of gaping SIEM “blind spots.” Lack of App Data Integration: One of the biggest roadblocks to SIEM success lies in the fact that many important applications simply do not generate log data that can be incorporated into the SIEM.This means that the sources of most data breaches and other security incidents will never be identified by a SIEM. Yet, mapping how these technical events relate to particular business risks is difficult, if not impossible, and is rarely accomplished successfully. Difficulty Mapping Technical Events to Business Risks: Most (sometimes all) of the log data processed by these systems are generated by hardware devices and operating systems.It is usually extremely difficult-even when the organization has dedicated SIEM monitoring staff – to figure out exactly who did what just by looking through long lists of system events across multiple logs. While simple alerts can be defined using rules which look at one or two details, conducting root cause analysis or trying to prove regulatory compliance can be impossible (or at last extremely time consuming). Disparate SIEM Logs: Correlating large sets of disparate logs based on timestamps or other markers does not make them magically useful.There are a number of reasons for these limitations: While SIEM systems provide significant value in these three areas, they are actually much more limited than many IT administrators, security officers and auditors realize. However, despite these key functionalities, there are several SIEM limitations that may result in security risks going undetected. To assist with regulatory compliance and reporting.To analyze and alert on anomalous events or suspicious trends in real time (or near real time).
There are a few common reasons why an organization would employ SIEM, including the following Security information and event management (SIEM) systems help organizations aggregate, correlate and analyze log data from numerous sources, such as network devices, servers and security systems (e.g., firewalls, anti-virus and IDS/IPS).
