The need for SIEM
No organization is immune to security attacks.
Irrespective of their size, organizations are facing attack attempts every day.
Although security devices such as firewalls, intrusion detection systems (IDSs), and intrusion prevention systems (IPSs) are capable of
detecting anomalous events and isolated attacks, they’re ill-equipped to deal with sophisticated attacks.
Be it ransomware or exploiting a long-known vulnerability in the operating system, hackers are employing distributed, slow, and targeted attack methods that are diffcult to detect with single-point security devices.
What enterprise security operation centers (SOCs) need is an intelligent platform that can tackle these types of attacks.
This is where security information and event management (SIEM) solutions and services come in.
Without the right SIEM solution, it’s nearly impossible for organizations to keep track of security incidents.
Understanding SIEM
According to Gartner, “SIEM technology supports threat detection and security incident response through the real-time collection and historical analysis of security events from a wide variety of event and contextual data sources.”
The main purpose of SIEM is to detect and stop security attacks by gathering and correlating activities happening across the network. To do this, many SIEM solutions or services offer different capabilities such as:
Log collection, processing, and archival.
Searching and reporting.
Real-time security monitoring.
End-to-end incident management and
automated workflows.
Threat intelligence.
User and entity behavior analytics.
