What Makes SIEM to Migrate to Cloud Platform

By StartUp City | Monday, February 11, 2019

Security in cloud platformSecurity is now essential in the digital realm. Nearly two decades ago Security information and event management (SIEM) approach were introduced by vendors in the security management landscape. Initially, its functionality centered on event correlation from perimeter security devices such as IDS/IPS and firewalls which led to the demand of eSecurity and Netforensics.

The SIEM system works upon the principle of aggregating relevant data from multiple sources and detecting deviations from the norms to take appropriate actions. Rules-based and employ statistical both SIEM systems correlate engines to establish the relationship between log entries. Since, long SIEM has worked on the same architecture of distributed data sources, processor, and indexers with a central database repository for analytics, reporting, and visualizing. This led to concerns of threat detection, forensic investigation, and incident response which requires infrastructure to upgrade hardware, load balancing server, and increasing storage capacity. To meet the needs of infrastructure cloud platforms are being touted as a solution.

Businesses have started to migrate to cloud slowly as they foresee the benefits of shifting from on-premise servers to cloud platform for SIEM.

• Organizations at times forced to ignore or purge valuable data because of unacceptable trade-offs taking place given the capacity of SIEM software. An approach of cost avoidance in SIEM could be of utilizing open source based Data Lake for longer-term investigations. It might reduce the software cost but will also lead to interoperability and fundamental security operations challenges. Security professionals will have to pivot back-end forth two security technology infrastructure for management.

• Security data grows at a rapid pace which requires similar growth in storage and processing power. Cloud platforms are apt to fulfill the requirements for higher operational efficiency and infrastructural capabilities.

• Shortage of skilled personnel also acts as a factor resulting in cloud migration. Organizations need employees to manage servers, storage devices, and network in case of an on-premise solution. Whereas in the case of cloud, all they need is to pay the vendor and rest is managed by their end.

The ever-changing landscape of SIEM security software to cloud holds possibilities for vendors as well. Cloud vendors should start to optimize this transition with service packages that are low in cost and good in service. Newly emerging start-ups in security will open a vast market for vendors to maximize.
