What is SIEM?

Security Incident and Event Management (SIEM) solutions
At its core, Security Incident and Event Management (SIEM) solutions offer organizations the ability to collect, aggregate, analyze, and store logs of network traffic and event data from various sources, including network devices, endpoint security, and intrusion prevention systems.
SIEM technology enables businesses with the ability to monitor all access points and threats in one centralized location, freeing up time for IT security professionals to focus on other tasks.

Who Should Manage Your SIEM?

Fully-Managed SIEM solutions have proved that they are an essential security solution that businesses need to invest in. However, when determining which SIEM solution is best for your business, knowing how you want to manage the solution is critical. Let’s break down the three traditional management levels: self-managed, co-managed, and fully managed, and the responsibilities of each.

Self-Managed SIEM: A self-managed SIEM solution used to be the traditional deployment model of SIEMs. Self-managed SIEMs are largely for enterprises with adequate IT resources, like time, personnel, and budget, to parse through and triage the alerts generated by the SIEM. Self-managed SIEMs can either be self-hosted or cloud-based.

Co-Managed SIEM: Because there continues to be a shortage of cybersecurity professionals, many enterprises are opting to invest in a co-managed SIEM environment. In a co-managed SIEM environment, your IT department will work alongside your MSSP to secure your environment, triage and respond to alerts, and handle incident response.

Fully-Managed SIEM: IT departments are being stretched to their limits while trying to keep their organizations secure from malicious outsiders. For this reason, fully-managed SIEM solutions, where the MSSP has complete responsibility for detection, analysis, containment, and response, have become increasingly popular. With a fully-managed SIEM solution, businesses are only responsible for leveraging the SIEM data.

Features of NextGen SIEM

With the ever-expanding complexity of the cybersecurity industry and the speed at which technology is developing, SIEM solutions offer features that equip businesses with the necessary tools to gain a holistic insight into their attack surface, mitigate increasing risks, maintain compliance, and have peace of mind. Typically, the features of a SIEM solution will include the following benefits:

Log Management/ assets secure and satisfy regulatory compliance requirements, log management must remain top of mind for businesses. In fact, according to the Center for Internet Security (CIS), the collection, storage, and analysis of logs are Critical Security Control. Without a robust log management solution in place, organizations are likely to have gaps in visibility into their attack surface, leaving them susceptible to increased risks or breaches. SIEM solutions should include log management capabilities like collecting and storing rich event log data for every user and device connected to the network so you can have an accurate, updated, and audit-ready trail of network activity data at all times; handling speeds over 10,000 events per second to make accurate log collection fast and scalable; and storing logs in a centralized management database (CMDB).
User & Entity Behavioral Analysis
Year after year, humans pose one of the largest threats to an organization’s security. Even with proper security awareness training and security measures in place, humans are still likely to fall victim to a cyber attack. This means that businesses need a way to quickly identify and remediate any user or entity anomalies. With user and entity behavior analysis (UEBA), SIEM solutions immediately detect any unauthorized network use, inappropriate employee behavior, or any other malicious anomalies found on the company network, allowing you to keep an audit trail of IP addresses, user identity changes, and geo-mapped user locations. UEBA also allows businesses to compare DHCP, VPN, WLAN, and Domain Controller login data to easily detect stolen user credentials.
Security Orchestration & Automation
A key aspect of simplifying cybersecurity management is automating incident response workflows through SOAR. With Security Automation and Orchestration features, SIEM solutions allow for deeper automation of security monitoring, reporting, and remediation tasks to dramatically increase response times to threats. This leaves businesses with unified operations that support a highly efficient, cohesive, and proactive cybersecurity solution and gives IT staff and other key stakeholders intelligent insight into all relevant network activity, from high-level usage statistics down to individual licensing information, serial numbers, device configurations, and more.

Real-Time Event Correlation
With real-time event correlation, businesses can automatically sift through hundreds of thousands of network events, quickly isolate the ones that may pose risk to the business, and respond accordingly. Not only does this SIEM feature enable a deeper detection by providing IT staff with the ability to correlate seemingly harmless events with malicious patterns of activity that may have otherwise been missed by an IT employee or traditional event correlation systems, but it also unifies traditionally siloed NOC and SOC efforts, which dramatically improves operational efficiencies, quickens response times to threats, and gives businesses a more holistic, unified view context.

Out-of-the-Box Compliance Reporting
Whether your business is required to comply with HIPAA, PCI DSS, NIST 800-171, CMMC, ISO 27001, SOX, FISMA, GDPR or the plethora of other regulatory frameworks out there, maintaining that compliance is not an easy task. With a SIEM solution like ArmorPoint, you’ll gain access to out-of-the-box reporting that allows you to quickly and automatically pull the required network data and information to demonstrate compliance at any time. Not to mention, you have the ability to export your logs instantly with ArmorPoint.

Unified Security Dashboard
Having the ability to monitor and control virtually every facet of your company’s security efforts from a single pane of glass is essential, especially when it comes to measuring business impact. A SIEM solution should offer highly customizable dashboards that allow you to monitor the security and performance of data for virtually every component detected in your network, including unified analytics across all environments, platforms, network devices, users, applications, and geographic locations in real time.

Vulnerability Management
A SIEM’s vulnerability management capabilities allow you to continuously hunt your network for malicious activity, securely mitigate threats, and use the knowledge gained to optimize response methods and processes in the future to completely minimize network vulnerabilities. Through vulnerability scanning, remediation strategy planning, and risk scoring, businesses will have a clear way to identify, minimize, and respond to threats in a way that will minimize the vulnerability’s impact on the business.

File Integrity Monitoring
While UEBA automatically detects and monitors all user activity on the company network, regardless of device, application, or geographic location to thwart any malicious or inadvertent activity that could put critical company files and applications at risk. With file integrity monitoring, businesses will have the intelligence and agility needed to detect and mitigate threats that could compromise the integrity of the files.
