SIEM managed Security Systems

November 6, 2020 5:26 am Published by

In the modern world, there is an ever increasing demand for security solutions to ensure that an
enterprise’s system is protected at all times. Security Information and Event Management (SIEM) is
software that allows security professionals of an organization to have a keen insight of the
operations that usually take place in their IT environment. It aggregates and analyzes activity
from many different resources across entire IT infrastructure. SIEM collects security data
from network devices, servers, domain controllers, and more. SIEM also helps to keep a track
record of the activities which are happening on a regular basis within their system setup. SIEM has
proven its functional capabilities for over a decade now, developing from the fields of log
management. SIEM software has efficiently been able to become software which is a fine
combination of security event management (SEM), responsible for inspecting and analyzing log and
event data in real time which helps to provide with solutions for threat monitoring, event correlation
and incident response, and security information management (SIM) used to collect, analyze and
report on log data. SIEM is at the moment a $2 billion industry.

Functional aspect of SIEM software

SIEM software mainly is of help to an Incident Response team of an organization, it provides detailed
reports and statistics about security incidents and alerts which are dependent on determining a
match with a certain pattern and thus being a concrete evidence of a security lapse. SIEM software is
constantly collecting and aggregating log data which is continuously generated within an
organization’s technological infrastructure. SIEM also is of immense help when it comes to detecting
activity that does not form any standard pattern by taking data and converting it into informational
charts which helps officials in determining the otherwise elusive patterns. SIEM software are also
used to automatically gather compliance data which produce reports helping to adapt to an already
existing security, governance and auditing setup. SIEM tools are also extensively used to aggregate
data that can be used for capacity management projects and are an essential service which help to
track bandwidth and data growth for a pre-determined period of time. This allows organizations to
plan for growth and budgeting for the long term business interests. SIEM solutions are usually used
in couples, where one works to provide solutions for data security and the other is deployed for
compliance solutions. SIEM software in organizations is sometimes majorly used to display
compliance with HIPAA, PCI, SOX and GDPR.

Why SIEM software is required.

SIEM software has already built a reputation for providing security solutions in the most critical
aspects of a technological infrastructure. SIEM software is mainly used for detecting threats to the IT
system of an organization, assisting in the investigation to eliminate such threats and sufficient
response time period. Apart from the already mentioned features, SIEM software categorically helps
in security monitoring on a basic level, forensics of security lapses and incident response, security
incident detection, threat response workflow and providing notifications and alerts regarding
impending or ongoing security issue.

Drawbacks of SIEM software

In spite of being a $2 billion industry, a recent survey points out the fact that only 21.9% of
companies who use SIEM software are getting value from it. This particular statistic quite clearly

brings out the drawback of SIEM software. Most SIEM applications are prone to providing significant
amount of false alarms because of gathering limited information about the root event. SIEM
applications are not capable of determining which data is sensitive and which data is not, thus being
unable to differentiate between warranted behavior and suspicious, malicious activity which might
cause damage to personal or company data. SIEM software is often subject to complaints suggesting
that it is extremely difficult to research and diagnose threats on the software.

Top SIEM tools and their requirements

1. Splunk: Gartner, the renowned research and advisory firm is of the opinion that Splunk is a
leading SIEM tool. It is a complete on-prem SIEM solution that Prime Infoserv integrates to
provide additional support for security monitoring and is capable of detecting threat on a
much more advanced scale.
2. QRadar: The feature that makes QRadar one of the more popular SIEM appliances is the
multitude of ways it can be deployed. Depending on the needs and requirements of an
organization, QRadar can be used as a hardware appliance, a virtual appliance or a software
appliance. Prime Infoserv holds deep expertise in using QRadar to provide solutions based
on advanced threat detection capabilities.
3. LogRhythm: This SIEM software is used largely by smaller organizations and Prime Infoserv
uses LogRhythm to enhance capability of a system’s ability to respond.
4. Helix : is a security operations platform with next-generation security information and event
management (SIEM) capabilities. Helix uses both signature and non-signature-based
detection applied to data from across enterprise to provide a holistic view of your security.
Prime Infoserv has deep expertise in implementing Helix.

SIEM integration and its benefits.

At Prime Infoserv, we majorly focus on adding depth to the data already collected by SIEM which
helps to counter threats intelligently. We excel at collecting event data of files from various data
stores to find out the exact details of each of the files that have been accessed on the network.
Prime Infoserv has over the years displayed great amount of efficiency in collecting DNS, VPN and
web proxy activity to provide elaborate solutions in terminating infiltrative attacks. It is of utmost
importance to us that we do not harass SIEM users with meaningless alerts and so we use user
behavior analytics (UBA) to determine and study patterns which provides security against all kinds
and forms of internal and external security threats. For years, our expertise in dealing with SIEM has
enabled us to provide users with analytics that are not available otherwise on the market,
investigative sectors specific to certain kind of alerts, in-depth and critically rich information with
clear mention of the best possible actionable course and world class integration of SIEM into an
organization’s workflow with regards to their technological infrastructure and IT environment.
