Every day the news is filled with an increasing amount of significant data breaches and cyber-attacks. Cybercriminals are always looking for flaws and opportunities to infiltrate your organization. To reduce and respond to these attacks in real-time, companies can make use of SEIM.  

So what is a SEIM, and why is it so important in helping keep your company safe from cyber-attacks.

A Security Information and Event Management or SEIM is security software that gathers log security data from diverse sources, categorizing and analyzing security alerts in near-real-time. SIEM integrates security information management, which stores, analyzes, and reports log data over time, with security event management, which monitors the system in real-time, correlates events, and generates alerts. A SEIM system employs correlation rules and statistical algorithms to extract relevant data from events and log entries.

The amount of data generated by an organization nowadays is too large to process manually, which is why an organization needs a SIEM system to monitor and detect suspicious activities. A SEIM’s primary function is to sort through thousands of data and prioritize security alerts to make managing security easier to handle. 

Gartner, for example, deems a SIEM systems small if it includes up to 300 event sources and 1,500 events per second while large SIEM systems can handle thousands of event sources which generates over 25,000 events every second. SEIM operations revolve around log management and the more diversified types of logs from more distant sources feed the SEIM, the more actionable reports it creates. By cross-referencing logs from various sources against correlation criteria a SEIM system can correlate relevant events. 

Now that we know what SEIM is, here are the top three reasons why having SEIM (Security Information and Event Management) software is important for your business. 

1. Detects Incidents

A SEIM system detects incidents that might otherwise go missed by examining log entries to spot signs of any malicious activity. Furthermore, because the system collects events from all sources across the network, it can recreate the attack timeline to help evaluate its nature and impact. The SEIM can then send security controls with recommendations, such as directing a firewall to prevent any security breach that can lead to a cyber-attack. 

2. Comply with Regulations

An organization without a SIEM must manually retrieve log data and compile reports however by utilizing SIEM systems to generate reports that cover all logged security events among all sources companies can meet compliance requirements.

3. Incident Management

A SIEM improves incident management by allowing the security team to track an attack’s progress across the network, identify compromised sources, and deploy automated countermeasures. 

We hope all of this festive cheer and advice is useful and can be used to ensure you get presents and not coal in the company stocking this year!
