We live in a digital era when modern businesses rely mostly on their IT infrastructure in order to conduct their daily activities. Of course, the reliance on IT brings a few advantages to organizations which become more streamlined and productive, but at the same time there is a persistent challenge that all businesses have to face: cybersecurity threats and incidents.
Cybersecurity incidents are not something unknown for the enterprises. Most businesses try to ensure the security if their IT infrastructure by establishing special safeguards. However, just slapping up some firewalls or subscribing to an antivirus software is not a serious approach anymore, not only because they are ineffective but also because the cybersecurity threats are continually evolving, and criminal hackers become more sophisticated. So, to resolve this problem, businesses have begun to turn to a more robust method of managing the security of their IT infrastructure: security information and event management (SIEM) software.
How does SIEM work?
Security information and event management (SIEM) software gives security professionals both insight into and a track record of the activities within their IT environment. It is a group of complex technologies that provide a centralized view into a network’s infrastructure. SIEM provides data analysis, event correlation, aggregation and reporting, as well as log management. While SIEM technology has been around for more than a decade, it becomes a critical component of a comprehensive security strategy in today’s threat environment.
The function of SIEM in cybersecurity is to provide a complete overview of a business’ entire IT infrastructure. Log data from applications, devices, networks, firewalls, antivirus software, wireless access points, and similar sources are collected to identify, analyse, and categorize different types of security threats the business may experience. SIEM products also provide dynamic, up-to-date information on the overall health of a business’ security system. This information can then be used to complete security compliance reports, analyse areas of weakness, and strategize solutions that may best protect the business’ entire IT systems in the future.
How Does a SIEM Help with Log Monitoring and Management
Effective log management is essential to an organization’s security. Monitoring, documenting and analyzing system events is a crucial component of IT security. Log management software or SIEM’s automate many of the processes involved. A SIEM handles the two following jobs that prior to today’s SIEM’s were handled individually:
- SIM – Security information management provides long-term storage as well as analysis and reporting of log data. This was and is still tricky and time-consuming if you must build your own connectors to your IDS/IPS, Firewalls, DLP solutions, Application servers and so many other log generating assets in your IT environment. Most SIEM’s have some connectors out of the box today.
- SEM – Security event manager provides real-time monitoring, correlation of events, notifications and console views. This is the key benefit of SIEM’s because a good SIEM will turn data into insights and a great SIEM, tuned correctly will turn insights into visual dashboards to assist analysts in uncovering anomalies and threats.
Effective SIEM solutions rely on logs from all critical components of a company’s business and network. These should include all firewall logs, logs from intrusion detection systems and antivirus system logs. As well, logs from primary servers should be included, particularly key application and database server logs along with the active directory server logs and web server logs.It is also important to protect your sources of log information, particularly when attempting to prove any legal culpability from computer misuse. This is because cyber attackers can try to delete or falsify log entries to cover their activity in your system.
Why SIEM is important and beneficial for the business?
To establish a capable cybersecurity team, SIEM solutions are a must-have for businesses in any industry. Today’s enterprises need a solution that can centralize, simplify, and automate security workflows to enable better analytics and incident response procedures. The key important pillars of a Modern SIEM are:
- Incident Detection
SIEM enables the detection of incidents that otherwise would go unnoticed. Not only can this technology log security events, they have the ability to analyze the log entries to identify signs of malicious activity. And by gathering events from all of the sources across the network, a SIEM can reconstruct the series of events to determine what the nature of the attack was and whether or not it succeeded.
- Efficient Incident Management
An SIEM solution can significantly increase the efficiency of incident handling, saving your security professionals time and resources. More efficient incident handling ultimately speeds incident containment, therefore reducing the extent of damage that many incidents cause. A SIEM improves efficiency by enabling rapid identification of all sources that were affected by a particular attack and by providing automated mechanisms to attempt to stop attacks that are still in progress.
- AI Cybersecurity
In recent years, advanced technologies like machine learning have made SIEM platforms more robust. It gives the companies the power to defend their businesses with complex threats before they become irreparable. It accurately analyzes event correlations for unique patterns that may lead to the detection of complex concerns over information and system security.
- Better Security Analysis
With SIEM solution, organizations get to integrate risk assessment services. SIEM tools make it possible for you to analyze network behavior in different circumstances and factors based on security sources for that particular condition.
- Proper Categorization
Businesses can categorize and standardize network logs for effective monitoring and achieve a responsive workflow with in-depth visibility of your backups and security. It provides your IT team with access to additional features like quick data encryption, system access management, SSO integration, and other quality management services.
Businesses now have multiple services available in the market that can accommodate any SIEM requirements. Some of the most powerful software are IBM QRadar and Splunk Enterprise Security. Based on your system requirements, you can decide what SIEM features you want from your SIEM solution. Moreover, considering elements like budgeting, storage array, customization preferences, and training needs is also essential. And finally – businesses must determine their current resource capabilities before integrating any SIEM tool into their systems.
