Organizations are building its threat hunting as a service model to address specific cybersecurity threats. But a key to achieving threat hunting maturity is to take a risk-based approach to enterprise's IT assets and the cybersecurity investments made to support it. Moreover, organization CISOs should work with the board to focus on the impacts of potential cyber attacks on business operations and protect against risks. When adversaries make strides through an organization’s defenses, most security products fail to alert and detect the intrusion.
To numb an attacker to freely roam around an organization's enterprise IT ecosystem for days, CISOs should increase their involvement in threat hunting spending decisions and build a robust cybersecurity strategy that involves in comprehensive threat hunting service complemented with incident response and SOC capabilities that detects and responds to malicious activities before a breach.
As enterprises are becoming more effective at tackling a broad spectrum of cyberthreat challenges, a breach can leave the victim organization in the dark to understand and discover exactly what happened, how it happened, and how to remediate the incident. Some organizations still think of threat hunting as an event collection of vulnerable systems and platforms from SIEM technology. However, in order to quickly detect and allow for quick investigation of potentially malicious and suspicious activities, they should be focusing on ways to proactively remove adversaries from their network and have the ability to record malicious activities for future investigations. Taking a broader view of incident response and monitoring beyond the SEIM can help cybersecurity practitioners find incidents and gain visibility on vulnerable technology systems.
In order to respond rapidly to a breach, organizations need to quickly obtain on-demand cybersecurity threat hunting as a service while maintaining a continuum business operation. Rather than investing in traditional cybersecurity defense tools, having the capability to stop adversaries before an incident allows the enterprise respond to a breach faster.
And when you add adversary techniques and procedures into the equation that effectively (and successfully) leverages the latest indicators of compromise, organizations spend less time to investigate what’s happening on its ecosystem endpoints and more time on day-to-day business operations.
Traditionally, organizations have focused their endpoint protection capabilities to either block or allow traffic within a certain application/solution. But malicious attacks may be extremely sophisticated, occurring as persistent threats that creates wide-ranging vulnerabilities in an organization’s digital enterprise. In response, it enables organizations to swiftly identify malicious activities and remediate the compromised hosts quickly.
The managed threat hunting as a service program provides organizations an early detection and reduces the risk of a missed malicious intrusion. That kind of proactive search of suspicious activity enables the security practitioner with the right tools and procedures to hunt and terminate cyber threats in an organization’s landscape immediately.
When it comes to proactive threat hunting at a scale, it starts with CISOs asking questions such as, “What steps can we take to assess and protect organization’s enterprise IT assets against potential exposure and ways to mitigate the broader impact of an attack across the enterprise?” CISOs also should be asking questions to help them respond to an intrusion faster and stop the potential breach. The benefits of threat hunting as a service don’t apply only to organizations with limited threat intelligence and monitoring skillsets. More mature organizations looking for added capabilities to augment their existing incident response and SOC operations also benefit greatly from threat hunting as a service. It is the ideal solution services for organizations who want to accelerate incident response, gain total visibility and bolster their cybersecurity strategy.
