Understanding and Proactively Countering Nesting Cyber Threats
In today's digital environments, organizations are constantly bombarded with a plethora of alerts signaling potential cyber threats. However, treating each alert in isolation may blindfold us to the lurking dangers that often manifest over time. It's akin to seeing individual pieces of a puzzle but failing to assemble them to reveal the complete picture.
Nesting threats, those insidious activities that stealthily grow and evolve within our systems, are particularly adept at evading detection when we don't put together the entire puzzle to understand related and interdependent alerts.
The Nature of Nesting Threats
Before diving deeper, let's define what nesting threats are.
These are multi-stage, covert cyber threats where an intruder, after gaining initial access, expands their presence, often quietly, over extended periods. Their activities can be sporadic, sometimes lying dormant for weeks or months, only to suddenly become active again. Such threats are meticulous, calculating, and patiently wait for the opportune moment to strike.
The Challenge of Disjointed Alerts
A primary challenge when identifying nesting threats is the disconnected nature of individual alerts over a vast period of time. When connecting these over such long periods, each working day provides hundreds of alerts, making the work of identification impossible using conventional approaches. A potential sign of a breach might emerge in January, and another related alert may pop up in March. Given the deluge of insights Security Operations Centers (SOCs) handle daily, it becomes a herculean task to correlate these time-separated events. SOCs operate round-the-clock, with different analysts covering various shifts. Thus, the person who saw the January alert is likely not the same person who encounters the March one. Without a continuous memory or a system to bridge this gap, it becomes virtually impossible to link these two seemingly disparate alerts. This discontinuity provides a fertile ground for cyber threat actors to infiltrate and navigate cloud environments.
The Imperative of Alert Correlation
For SOCs to stand a chance against nesting threats in the cloud, they must embrace the concept of insights instead of alerts. Here's why:
Historical Context: By connecting alerts over time, analysts gain historical context. They can discern patterns, repetitions, and sequences of alerts, enabling them to proactively hunt, investigate, and neutralize nesting threats before they escalate.
Reduced False Positives: Correlating alerts can help in filtering out false positives. A standalone event might seem harmless, but when seen in conjunction with past alerts, its malicious nature might become apparent.
Efficient Resource Allocation: Not all alerts warrant the same level of attention. By understanding the interrelations between different alerts, SOCs can prioritize their response, focusing their resources on proactively countering the most pressing threats, often nesting threats.
Recognizing the importance of insights is one thing; implementing it effectively is another. Here's how SOCs can start:
Invest in Advanced SIEM Systems: Security Information and Event Management (SIEM) systems that offer advanced correlation capabilities can automatically link related insights, making it easier for analysts to spot patterns.
Continuous Training: Regularly train SOC analysts on the importance of historical data. Encourage them to always look beyond the immediate insight and delve into past related events.
Collaboration and Communication: Promote a culture where analysts freely communicate their findings, especially if they suspect they've stumbled upon an element of a nesting threat.
Leverage Nesting Threat Intelligence Platforms: These platforms can offer insights into known threat patterns, enabling analysts to compare real-time insights with known threat behaviors.
Or organizations can use Cyngular's ClouDFIR platform. Cyngular's forward-thinking strategy to address nesting threats signifies a major shift in approaches to cybersecurity. While many solutions traditionally react to threats, Cyngular stands out by actively seeking and addressing them before they escalate. This is achieved by identifying typical behaviors of threat actors and catching those small, yet critical, deviations.
Conclusion
The realm of cybersecurity is in constant flux, with adversaries continually devising new tactics. Nesting threats represent one such evolving strategy, exploiting time and discontinuity to evade detection. By understanding the importance of fast insights and investing in systems and practices that prioritize it, SOCs can tilt the balance in their favor – with As cybersecurity challenges grow in intricacy, it's crucial our solutions remain cutting-edge. Cyngular's unique blend of insight and emphasis on directly and proactively neutralizing threats in their early stages solidifies its position as a leader in today's cybersecurity landscape.
