Companies wage war against competitors every day to gain an edge with clients or customers. However, there is another battle that they must gear up for. It is a skirmish that can happen anytime with no frontlines drawn. Enemies can attack at will and without warning. Worst, the opponent has already laid a security time bomb waiting to explode. Losing this fight can mean massive revenue losses.
Corporate executives put much weight on this matter to avoid a backlash from directors and consumers alike. But as the efforts of bots and hackers intensify to penetrate their network, businesses that heavily rely on computer infrastructure must fortify their defenses. Pre-installed threat detection tools might not work for they cannot respond in real time. Therefore, establishments that are prone to attacks must consider security information and event management systems.
Early adopters of SIEM were enterprises who needed better measures to audit whether compliance in handling sensitive data are being met or not. The software provided monitoring and reporting needed to meet regulations in protecting personal data which are used by banking institutions, public companies, and health insurance providers. Over time, the demand by larger corporations for reliable security gave the market a significant boost.
SIEM tools do not stop in just raising alarm over malicious traffic or potential breaches. Rather, it also analyzes these occurrences to help formulate solutions. It comes in two segments: security event management (SEM) and security information management (SIM). SEM is responsible for real-time monitoring and notifications regarding attacks. Logs from various endpoints such as devices and operating systems are then relayed to the SIEM using encrypted User Datagram Protocol or Transmission Control Protocol.
The data collected will be correlated from previous occurrences and the security operations center that maintains the software will be alerted of imminent threats via secure Hypertext Transfer Protocol connection. Then, the security event manager stops the progress of the threat and updates the correlation between the latest attacks and previous ones of similar nature. If needed, access requests to troubleshoot the SIEM are then sent by an engineer through Secure Shell Protocol. All information is available to the client via a console or dashboard that can be accessed via HTTPS.
Meanwhile, SIM aggregates all log files so that it may analyze trends that will improve the system’s response for future attacks. These improvements can be attained either by the comments made by the operations center engineer or through deep learning using artificial intelligence. Retaining data will also be helpful during forensic investigations of network breaches. The logs can also be converted to reports that will safeguard sensitive data to comply with security and governance protocols.
Companies will shell out a fortune to use security event and information management software. However, that sum is worth it considering its preventive measures. Businesses that deal with delicate information such as banks and e-commerce facilities must use this because attempts to steal data happen every day with no warning. Should there be a security breach, money can be stolen from people’s accounts or personal information can be used for identity fraud. Irate customers can then sue for exposing their sensitive data and the company will end up paying millions due to damages. Worst, their credibility is lost and more customers may pull out.
So, it pays to invest in a SIEM software as early as possible. As this security system is set in motion, it will continually improve and weed out false alarms with more data gathered. However, corporations and medium-sized businesses should not be contented in having the software alone. Rather, they must look for a SIEM provider with a 24/7 security operations center. That way, threats are averted in real time and the response team can write scripts to improve the detection accuracy of the software based on their findings.
This is a war that you cannot afford to lose. Thus, let SIEM be the fortress that makes your operations run smoothly by constantly winning the battle against security threats.
