In any case, when choosing a specific product, you should focus on many parameters, among which we highlight the centralized collection, processing and storage of information, notification of incidents and data analysis (correlation), as well as the coverage of the corporate network.
#SECURITY INFORMATION AND EVENT MANAGEMENT SIEM HOW TO#
For example, some modern products have analytical functions, that is, they not only issue the reports and indicate the potential problems, but also know how to analyze events themselves and make decisions on informing about certain events. Moreover, the development of SIEM platforms does not stand still. But along with this, they are an important part of the enterprise security system, although not a critical one.
And, of course, they cannot fully cover the information security issues at the enterprise. For example, they do not know how to classify data, they often work poorly with e-mail, they have blind spots in relation to their own events. At the same time, SIEM platforms have a number of limitations. Among them: timely detection of targeted attacks and unintentional violations of information security by users, assessing the security of critical systems and resources, conducting incident investigations, and much more. What opportunities are opening up? SIEM helps to solve a number of problems. Then (again, in accordance with the specified settings) the notifications are sent that certain actions of the equipment, programs or users may be potential security problems. The identification and classification of events occurs after collecting information (this procedure occurs automatically at specified intervals). Such data is provided through the collection and combination of network device log data. But the main thing, of course, is the detection of potential gaps, as well as the localization and elimination of existing threats. With their help, for example, it is possible to understand how the network infrastructure functions and how to develop a plan for its optimization. This data is not necessarily associated with security. SIEM programs collect information from servers, domain controllers, firewalls and many other network devices and provide it in the form of convenient reports. Such systems in real time provide an analysis of security events, as well as the activity of devices and users, which helps to respond to them before significant damage is done. In a few words, SIEM technology gives administrators an overview of what's happening on the network. Read the best of such products according to Gartner experts in our review, and learn about the main features from our comparison table.
But there are the tools, which collect reports on the work of the entire corporate infrastructure - SIEM (Security Information and Event Management) system in one place. And monitoring their work individually can be quite difficult - the larger the enterprise is, the more burdensome these tasks are. Modern corporate IT infrastructure consists of many systems and components.
