Security information and event management (SIEM) tools provide comprehensive data analysis, alerting, and reporting features to help IT teams identify and respond to cyber threats quickly. But not all SIEM solutions are the same, so it’s essential to evaluate your options before carefully deciding which one to deploy. The following tools are critical for configuring a robust SIEM.
- A layered approach
You must have visibility across your entire environment to configure a complete SIEM cyber security system. That includes surveillance from endpoints and servers up to cloud platforms. In other words, you need to have both on-premises and cloud solutions in place that you can integrate.
- A Holistic Framework
Without a holistic framework, you’re better off with no solution. Unfortunately, most resolutions are developed in silos and rarely address security as a whole. As a result, many organizations have multiple tools that don’t communicate or interact well with each other.
To be effective, your SIEM must work seamlessly across your entire organization – from IT and Security teams to HR departments and even executive leadership.
- Data Analysis
After collecting your data from a SIEM, it’s essential to know how to analyze it. Start by setting up regular, weekly analyses. Next, set up dashboards and alarms to help notify you of any potential issues or red flags. Finally, make sure your team understands each metric and how they should respond if something looks off.
- Automation And Alerting
If you want to avoid an overburdened security analyst, it’s crucial to use rules and automation. The more time you can free up for analysts, the better. When creating alerts, be sure they are well-defined and actionable. If they aren’t, adjust them until they are. You want your alerts to be clear enough that any team member could take action on them without hesitation or confusion.
- Anomaly Detection
Also known as outlier detection, anomaly detection involves monitoring activity to identify data that doesn’t fit within a given context. For example, if you have a system that monitors network traffic and a strange spike occurs, it could indicate malware installations are happening on your network. This type of analysis can detect internal and external threats against your business assets.
- Log Rotation And Retention Policies
Regular auditing can help you identify flaws and weak spots in your system. Then, you can fix these issues before anyone else can exploit them. As such, you must have a log rotation policy in place.
- Test Your Configuration
Now that you’ve configured your new SIEM cyber security system, it’s time to run some tests on your network to ensure that everything is working as expected.
- Regular Auditing And Reviews
Regular auditing and reviews of your SIEM systems allow you to ensure that everything is functioning as intended. For example, you can keep tabs on all of your logs, audit any suspicious activity, and detect common threats before they cause severe damage by frequently utilizing security analytics.
- Manage Multiple Systems Effectively
Monitoring dozens of individual systems for threats and vulnerabilities can be time-consuming. However, a SIEM system can aggregate log data from all of your networks and applications in one place.
- Customize For The Security Operations Center (SOC) Environment
Every IT environment is different, and so are its security needs. When configuring your SIEM, ensure you accurately target what makes sense for your business. For example, is there an unusually high amount of network traffic? Are there specific threats that affect your industry? When creating a custom plan, these questions should be at the forefront of your mind.
To fully configure a robust SIEM, you must consider many different factors. It can be unclear if you don’t know what you’re doing. For example, platforms like ConnectWise Security Management are an excellent option for companies looking for a single tool that can do it all.
