SolarWinds Security Event Manager (SEM), is a security information and event management (SIEM) virtual appliance that adds value to existing security products and increases efficiencies in administering, managing, and monitoring security policies and safeguards on your network. SEM previously know as Log & Event Manager.
SEM provides access to log data for forensic and troubleshooting purposes, and tools to help you manage log data. SEM leverages collected logs, analyzes them in real time, and notifies of a problem before it causes further damage. For example, advanced persistent threats can come from a combination of network events such as software installations, authentication events, and inbound and outbound network traffic. Log files contain all information about these events. The SEM correlation engine identifies advanced threat activity, and then notifies of any anomalies.

Log Monitoring Tool That Includes Cyber Threat Intelligence Feeds
Help improve security with threat intelligence tools
There’s an increase in the volume of DDoS, botnet, and malware attacks happening every day. In this era, implementing a robust cyber threat intelligence framework for collecting, consolidating, and analyzing all your log data and threat intelligence feeds in one place is a smart move for data security and the company’s bottom line.
SolarWinds Security Event Manager (SEM) is an on-premise, advanced SIEM tool built with an active threat intelligence management system in the form of threat feeds designed to automatically detect and respond to user, application, and network threats.
Flag threat events with cyber threat intelligence frameworks

Leverage threat intelligence tools to automate detection
Imagine that abnormal privileged user activity occurs outside of the usual working hours, which can be a sign of malicious internal behavior. Using its integrated threat intelligence, SEM is built to compare security events against threat feeds that are updated daily, and alert when one of the source or destination fields hit a blacklist IP address or domain to automatically pinpoint potential security issues like phishing attempts, malware infections, and external cyberattacks.
Security Event Manager also comes with over 700 built-in correlation rules and hundreds of active responses that admins can configure to automatically trigger to respond to security events in real time. You can select from predefined rules or manually define rules to set operational thresholds, easily automating how SEM mitigates immediate threats and generates relevant notifications in response to defined conditions.
Gain powerful insights by using threat intelligence feeds

Make the right incident-response decision using Active Response software
Help increase response capabilities as threats grow
You may not be able to respond to threats at scale if you subscribe to the prehistoric method of manual research, validation, and remediation. New threats are developed and deployed every day, and existing threats we thought we’d handled are evolving to cause greater damage. You could invest an entire day in the manual response method, and you’d still be behind due to the sheer volume of potential threats in the queue still needing to be investigated. Respond to threats at scale using SolarWinds® Security Event Manager (SEM) security incident management software with Active Response.
Respond to threats as soon as alarms are triggered
Active Response provides preconfigured, customizable actions for incident response based on which trigger conditions are satisfied, enabling you to proactively hunt and stop threats. Security Event Manager incident response solutions are designed to ingest threat intelligence findings and act on unique user-defined actions. Simply kick off an automated email to your team, actively block a threat detected at your firewall, disable an Active Directory account whose actions may place your enterprise at risk, and more.
Easily configure incident responses to complex threats
Manual response can be a task requiring a certain level of technical breadth to understand the risks and consequences of the selected remediation path. By the time IT professionals have thoroughly researched a potential threat, it may have already escalated into something more serious. Remove the manual research involved in incident response and let the security incident management software in Security Event Manager with Active Response do the heavy lifting.
Automate SIEM Log Aggregation, Analysis, and Reporting
Aggregate all SIEM logs at one location
Detect security risks with real-time analysis
The SIEM management capabilities of Security Event Manager help accelerate threat detection and empower your IT team to analyze SIEM log data in real-time. With integrated threat detection capabilities, SEM is designed to help you dig deep into security event logs and investigate incidents faster. SEM is built to help you easily ascertain the cause and effect of events generated across the network infrastructure. The advanced search and event-time correlation capabilities in SEM can help simplify and expedite forensic analysis and network security audits. Also, its SIEM log analyzer tool is designed to easily forward correlated log data to an external source for further analysis if and when required.
Monitor proactively and automate remediation
Security Event Manager is built to provide continuous SIEM monitoring to handle security breaches and incidents better. You can constantly monitor your files and folders with its SIEM capabilities to track any permission changes or data modification to identify suspicious activities. SEM’s USB security software provides proactive USB device monitoring to avert IT security risks like data leaks or other malicious threats. The SIEM monitoring tool capabilities of SEM helps to optimize security threat resolution with automated responses. You can also initiate real-time threat remediation by configuring threshold-based alarms and notifications.
Sustain security posture with integrated reporting
SolarWinds Security Event Manager is built to provide an integrated compliance reporting tool for simplified and faster compliance audits. SEM’s standardized reports available out-of-the-box can assist you in demonstrating various industry-specific regulations like HIPAA, PCI DSS, SOX, FISMA, NERC CIP, FERPA, GLBA, GPG13, DISA STIG, and more. You can easily conduct forensic investigations with SEM’s detailed drill-down reports. In addition to industry regulation compliance, the compliance reporting can also help you demonstrate and ensure that any internal security policies are effectively implemented at all times.
File Integrity Monitoring Software
Track file and directory access, movement, and shares

Use a file integrity checker to detect malware threats
Malware and advanced persistent threats (APTs) often access and modify local files. Security Event Manager file integrity monitoring software is built to correlate logs from anti-virus tools and IDS/IPS with file audit events to more easily detect APTs, malware, and improve FIM security.
You can also configure Security Event Manager’s integrated incident response actions to trigger when certain conditions exist that can kill a malicious process or quarantine systems for complete endpoint protection.
Demonstrate FIM security compliance requirements
Many industry compliance standards—like PCI DSS, SOX, HIPAA, NERC CIP, FISMA, and SANS Critical Security Controls—require you to both secure sensitive data and demonstrate how you’ve secured it.
Security Event Manager file integrity monitoring is built to help you more easily demonstrate these requirements. You can use built-in file integrity monitoring templates to audit key files, folders, and generate out-of-the box reports to help demonstrate compliance.
Easily perform Windows file integrity monitoring
With a simple configuration process, you can integrate Security Event Manager into your Microsoft OS by following steps from SolarWinds Customer Success here.
In line with the SolarWinds commitment to customization, you have the option to set up your Windows FIM tool to monitor either individual nodes or an entire connector profile. During the configuration process, you can customize the files, folders, or access criteria you want to monitor. You can also specify the conditions for the FIM security monitoring, so highly critical data can be scrutinized more thoroughly than less sensitive files.

Benefits
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.
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.
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.
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.

System Requirements
March 26, 2020
Use the following tables to plan your Security Event Manager (SEM) deployment to suit your network environment.
Server sizing is impacted by:
- Number of nodes and network traffic. Consider event throughput and performance degradation when planning the size of your deployment. As the number of nodes and network traffic increase, the size of your deployment will need to grow with it. For example, if you are running a small deployment and begin to notice performance degradation at 300 nodes, move to a medium deployment.
- Storing original (raw) log messages in addition to normalized log messages. If you will be storing original log messages, increase the CPU and memory resource requirements by 50 percent. See your hypervisor documentation for more information.
