Many organizations now operate online which makes them predisposed to attacks that, if not well prevented and contained, can cause damaging downtime and even business closures. An organization can be adversely affected if cyber attackers get access to their sensitive information. This makes it essential that any business operating online finds the best way to quickly identify and contain threats. Security Information and Event Management is an effective way that businesses are turning to for their online security.
Security Information and Event Management (SIEM) combines the SEM and SIM and provides real-time analysis of security alerts. The Security Information Management (SIM) is used or long-term storage and analysis of data. The Security event manager (SEM) is used for real-time monitoring, notifications, and correlation of events.
Security Information and Event Management records data from across an organization’s internal network of tools, and it identifies potential threats. Once it identifies a potential threat, it communicates with other security systems to stop the unwanted activity.
Some of the benefits of using SIEM are:
- Parsing log normalization and categorization occurs automatically, regardless of the type of computer.
- Visualization with SIEM using security events and log features aids in pattern detection.
- SIEMs can detect covert, malicious communication and encrypted channels.
- Cyber-warfare can be accurately detected by SIEMs.
- Protocol anomalies which can indicate a security issue can be identified with SIEM pattern detection, alerting, baseline and dashboards.
- SIEM visibility and anomaly detection can help detect polymorphic code.
SIEM is the solution that IT professionals need to quickly detect threats before they cause irreparable damage.
SIEM works by:
- Collecting log information
- Generating compliance reports
- Aggregating security data
- Analyzing security data
- Correlating security events
- Detecting potential indicators of a breach
- Presenting potential indicators of a breach to security professionals.
To get the most out of your SIEM solution, it must include some key capabilities.
The following are the key capabilities that every SIEM must have:
- Security Event Correlation: This is a very essential SIEM capability. SIEM analyses all accumulated data for potential threats.
- Security Alerts: A solution is of no use if it does not update your IT security team with all possible threats. Security alerts helps your security team to quickly detect all threats and quickly spring into action to get rid of them.
- Log Management: This allows your security team to easily access log files from multiple hosts. Log managements also reformat data, making analysis quite easy.
- Threat Intelligence Feed Connection: This helps you to draw from as many feeds as possible.
- Report Presentation: Your security team must first understand what a threat looks like before they can do what is needed. Your SIEM solution should present the security information in an easy-to-understand format.
- Dashboard: Your SIEM system must have a good and simple user interface. A simple user interface makes it much easier to identify threats. It allows your analysts to spot any anomaly as soon as it pops up on the display.
- Machine Learning: This allows your SIEM solution to automatically find threat indicators and adapt to new strategies.
