Benifits of SIEM Tools.
SIEM TOOLS AND ITS
BENIFITS
Security incident and
event management (SIEM) refers to the process of recording, monitoring,
correlating, and analyzing the security events in an IT environment in real
time. No matter the size of a business, SIEM tools can have significant
benefits for everything from compliance reporting to stopping attacks. Any
managed services provider (MSP) can benefit from having SIEM software in its
portfolio.
SIEM tools combine
security information management (SIM) and security event management (SEM)
functionalities. They use log data flows from different areas of an
organization to create a real-time picture of potential threats to the IT
environment, enabling your cybersecurity to be proactive rather than reactive.
By relying on data from the variety of hosts in an IT environment, SIEM tools
can provide you with a broad understanding of what is happening at every level
of a business.
Why a SIEM
tool?
As an MSP, you know
how important it is to provide your customers with the consistent high-quality
service they’ve come to expect from you. SIEM tools can help you do that by
providing simplified compliance reporting, greater visibility into IT environments,
and scalability as business grows.
For MSPs, including
SIEM tools in your portfolio will allow you to provide your customers with
stronger cybersecurity support thanks to centralized logging capabilities. This
can lead to increased revenue and improved profit margins, as well as better
customer relationships and loyalty.
SIEM benefits
The SIEM process is
one of the most critical branches of cybersecurity. By collecting, naturalizing, and correlating log data
from an organization, SIEM tools help you reduce security breaches with
proactive security.

Data
aggregation and visibility:- Visibility into your entire IT environment is one of the biggest
benefits of SIEM. This visibility goes hand in hand with the way that logs are
normalized and correlated in a SIEM tool.No matter the size of a business,
there are likely a variety of different components in the IT environment, each
of which is generating, formatting, and sending huge amounts of data. Not only
are these components producing tons of data, they’re likely each doing so in
different ways. Trying to make sense of all that data manually is a nearly
impossible task, and one that would necessitate devoting a huge amount of time
and energy to a job that can easily be automated. That’s why the SIEM
capabilities that relate to data aggregation and normalization are so
beneficial. Not only does a SIEM tool collect and store the data from the security tools in your IT environment in a centralized
location, it normalizes them into a uniform format so you can easily compare
the data. The tool also analyzes and correlates this data, finding connections
that can help you detect security incidents quickly.

Incident
detection:-Many of the hosts on
your system that log security breaches don’t include built-in incident
detection capabilities. That means they can observe events and produce log
entries, but can’t analyze them for potential suspicious activity. However,
because SIEM tools correlate and analyze the log data that’s produced across
hosts, they’re able to detect the incidents that might otherwise be
missed—either because the relevant logs were not analyzed or because they were
too widely separated between hosts to be detected. As cyberattacks become
more sophisticated, they’re able to avoid detection better than ever. By
gathering and normalizing log data from different systems, a SIEM tool can
see the different elements of attacks that are seen on the different hosts
within your system. For example, one part of an attack might be seen on a
computer’s operating system, while another part might be seen by a network
intrusion prevention system. By correlating log data from each host, the tool
is then able to reconstruct the series of events to determine the precise
nature of the attack and whether it succeeded. Once the correlated event has
been detected, the tool can send alerts to notify the IT team of the full scope
of the attack and direct them to the associated log data so that they can
respond accordingly. There is a huge difference between detecting an
attack as it’s occurring versus detecting it long after it has already
succeeded. By detecting incidents that might otherwise go unnoticed until much
later, the SIEM workflow can limit the scale of damage that might result from
the threat.

Improved
efficiency:- SIEM tools can
significantly improve your efficiency when it comes to understanding and
handling events in your IT environment. With SIEM tools, you can view the
security log data from the many different hosts in your system from a single
interface. This expedites the incident handling process in several ways. First,
the ability to easily see log data from the hosts in your environment allows
your IT team to quickly identify an attack’s route through your business.
Second, the centralized data lets you easily identify the hosts that were
affected by an attack. SIEM tools also include automated mechanisms that
use data correlation and analysis to stop attacks as soon as they are detected.
These capabilities enable SIEM tools to stop attacks while they’re still in
progress and to contain hosts that have already been compromised, thus reducing
the impact of a security breach. Working more efficiently, especially when
it comes to ongoing security incidents, is a huge asset for MSPs to be able to
provide their customers. By responding quickly to perceived events, SIEM tools
can help you reduce the financial impact of a breach—as well as the amount of
damage that occurs in the first place.

Simplified
compliance reporting:- Practically
every business, no matter the size or the industry, has at least some
regulations that it needs to comply with. Ensuring that you’re abiding by those
regulations and that you can prove your compliance can be a difficult and
time-consuming task. Luckily, thanks to the collection, normalization, and
organization of log data, SIEM tools can help simplify the compliance reporting
process. In fact, the benefits of SIEM tools as centralized logging solutions
for compliance reporting are so significant that some businesses deploy SIEMs
primarily to streamline their compliance reporting. Most compliance
reporting demands rich customized reports involving all the relevant logged
security events from across the various hosts in an IT environment. Without a
SIEM system, it’s unlikely that you have robust centralized logging
capabilities. That means you may need to manually retrieve data from each of
the hosts in your IT environment or be forced to generate individual reports
from each host and then reassemble them into a single report. This is
particularly difficult given that all the different hosts in your system are likely
logging their data differently, which makes correlation an enormous effort
without SIEM tools that automatically normalize your log data. SIEM tools
can save businesses both time and money by simplifying compliance reporting to
make sure MSP customers are not in violation of any regulations. Without
accurate reporting to prove compliance, businesses may face hefty fines and
loss of accreditation. With SIEM tools, MSPs can easily generate reports that
provide details on their customers’ compliance with the relevant regulatory
protocols.
