How SIEM Enables You to Take a More Proactive Approach to Security

Author: Neil Christie, CISSP, HCISPP, Director of Cybersecurity Operations/Tuesday, November 13, 2018/Categories: Security Services

The news is filled with stories about cybersecurity threats, from ransomware to Facebook hacks. Major industry conferences have sessions on cybersecurity headlining the agenda. This isn’t hype. The threats are real. The risk is real. And the likelihood of a data breach increases every day. 

That’s why smart organizations are searching for ways to proactively address security threats instead of reacting to them after serious damage has been done. This has led to an increase in spending on security information and event management (SIEM) solutions. In fact, Gartner expects the SIEM market to more than double from $2.167 billion in 2016 to nearly $6 billion in 2021.

SIEM brings together security information management, security event management, security event correlation, and log management into a single solution. The job of SIEM is to correlate security-related data from a variety of sources, such as end-user devices and servers, as well as firewalls, intrusion prevention systems, antivirus software and other security tools. Analysis of this data makes it possible to automatically identify abnormal activity and issue an alert. Security personnel can then analyze the alert in the context of all the collected log and event data. A single management interface makes it easier to investigate security incidents and weed out false positives.

SIEM succeeds by looking at the bigger security picture and showing you what’s happening in your IT environment in a way that single-purpose security solutions cannot. Best-in-class SIEM solutions provide complete visibility into your environment and root-cause analysis of security alerts. This allows security analysts to make better, faster decisions about suspicious activity and take appropriate action based on the level of risk.

Implementing and managing SIEM is no small task. Security managers and system administrators have to program the routing of data from a wide range of sources so that it can be properly aggregated, normalized and correlated. Outside consultants might be needed to assist. As a result, SIEM deployment can be a lengthy, complex proposition. If the SIEM system is not set up properly, organizations can be overwhelmed with alerts that aren’t serious, and few organizations have the in-house expertise to separate serious threats from noise and fine-tune the system.

That’s why SageNet has developed a SIEM-as-a-Service solution. Our cloud-based SIEM platform connects securely to your environment and collects securely-related machine data from all locations and sources. Automated machine learning technology correlates the data, generates alerts and sends them to your IT team for review. Personnel in SageNet’s Security Operations Center (SOC) work with you to establish relevant alerts and tune the alerting system to minimize false positives. Ongoing alert evaluation and use case development can also be performed as necessary.

SageNet’s SOC-as-a-Service solution takes this a step further. Our certified security analysts review and evaluate alerts and provide context prior to forwarding them to your security operations team. Our SOC personnel monitor and investigate events around-the-clock so you can focus your efforts on high-priority issues. We also manage the alert generation content to ensure we are triggering on the latest attacks, all in an effort to give your organization the ability to identify an attack earlier in the attack timeline and create the peace of mind that someone is focused on this identification.

Organizations can no longer afford to turn a blind eye to security or simply react to security incidents. They need to take a proactive approach by continually analyzing security event data and responding quickly to potential threats. SIEM gives organizations the visibility and single-pane-of-glass management they need, and SageNet’s SIEM-as-a-Service combined with SOC-as-a-Service solutions add cloud flexibility and simplicity with expert content, management, monitoring, investigation and support.
