The cloud has become the primary environment that businesses use to store and manage data. According to a recent study, 52% of today’s enterprises are cloud-first. And it’s expected that this could grow to 77% within the next two years.

Because of this shift, Security Information and Event Management (SIEM) has become a common security control organizations use to protect cloud-based information. At its core, SIEM is a log-monitoring technology that helps businesses get a comprehensive perspective on threats that exist on their various cloud-based systems.

Cloud-managed SIEM is the primary way businesses discover probes and breaches. It also ensures compliance with regulatory standards like PCI and HIPAA that require log monitoring and retention.

How SIEM Protects Your Cloud-Based Data Against Cyberattacks

LBMC Information Security protects your cloud environment against potential threats by monitoring, reviewing, and translating data into actionable insights through four key steps.

Step 1: SIEM aggregates logs into a central location. Every day, your servers, firewalls, routers, and applications generate millions of lines of logs. The first thing SIEM does is aggregate all of that information into one centralized location.

Step 2: SIEM processes and normalizes logs into a standard format. One of the challenges of managing a cloud environment is the multiple log formats you receive from various sources, making it incredibly difficult to analyze potential threats. A SIEM system gathers all logs from various sources and normalizes the data into a single, standard format that can be efficiently analyzed.

Step 3: SIEM correlates and enriches all logs to bring data to life. When evaluated individually, most log entries do not contain enough context to be useful. Correlation is what helps translate raw data and information into the actionable insights you need to protect your cloud-based data. The picture is clear when log data is correlated from servers, firewalls, applications, and asset databases.

Step 4: SIEM analyzes and identifies potential threats specific to your organization. Once all log data is collected and contextualized, SIEM goes to work to identify the greatest potential threats. What makes SIEM so valuable is the endless number of threats that can be monitored. For example, you can set up an alert as detailed as “when someone logs into the accounting server between midnight and 5 a.m.”

SIEM can discover potential issues that many of today’s security systems simply cannot detect. Investing in advanced security systems now will significantly lower your chance of experiencing a security issue, while also giving you the peace of mind in knowing that all of your security systems are in sync, monitored, and functioning properly.
