Threats to organizations increase by the day, and many have responded by moving towards the integration of siem (secure incident and event management) and threat analysis tools in order to detect malicious activity, hunting aims to detect threat actors early in the cyber kill chain by investigating the it environment for signs of an intrusion.
Practitioners provide awareness on the latest cyber threats, and can help set the foundations for the implementation of a incident response team and a security operations center, there is the task of hunting for advanced attacks that often goes unnoticed in rule based systems like siem.
Managed threat services establishing adaptive cyber vigilance staff shortages, the need to cut costs, and a desire to shift capital expenditures to operating expenses are a few of the issues that lead many organizations to hire managed security service providers, a successful threat hunting operation depends on complete visibility across the entire enterprise including every endpoint and the unfiltered data needed to understand every process running on that endpoint.
Integrate all the key elements you need to detect threats early and respond rapidly and decisively, cyber fusion and soc are closely connected entities of the incident response chain that are vital for an organization to gain greater visibility of its networks and systems, their posture against threats, and developing an appropriate set of processes to address and mitigate them.
You need the ability to distill information about potential threats simply by excluding background activity at the outset, identify potential threat activity on your network, and view everything through a user-friendly online interface, in the same way, security information and event management (siem) is an emerging technology solution that has been developed with the goal of introducing greater intelligence and automation into the collection, correlation and analysis of log and alert data, which, in turn, should allow security analysts to focus on what is most important.
Siems lack the necessary data retention to effectively utilize threat intelligence, the damage potential of ransomware, zero-day malware and data theft be it financial, personal identifiable information or intellectual property is incalculable and the threat is real and present, as a result of this, your sensors will have to power threat hunting by providing an incredible amount of visibility into your network, as well as delivering sensor performance and flexibility to improve any of your existing security tools.
Initial siem technology merely parsed logs; now those systems are ingesting threat feeds, adding host agents and passive sensors.
A siem monitors and analyzes all your devices logging data – including workstations, servers, routers, firewalls, switches, intrusion detection systems (ids), intrusion protection systems (ips), and any other device that produces data – to alert you to potential indicators of compromise and enable threat intelligence and incident response.
