Cyber Threat Hunting

Cyber Threat Hunting

The majority of organizations use an “alert” driven approach to cyber security events. This puts your organization already at a disadvantage, because your organization is reacting to an event that already happened. Be proactive and make it more difficult for threat actors to succeed in their mission!

Cyber Threat Hunting – Tailored to Your Needs

Our Cyber Threat Hunting service provides the following benefits

Proactive cyber security concept

Traditional cyber security efforts were event driven and are therefore reactive by default. Cyber threat hunting, however, uses human and machine driven efforts to identify unexpected activities on computer systems and network traffic to determine if they pose a threat to the organization.

Establish asset integrity confidence

One of the primary goals of cyber threat hunting is to identify unknown or suspicious activity within a corporate network. One aspect of cyber threat hunting is to obtain visibility into the integrity of network assets (ie. desktops, servers, laptops, etc) to see if they are compromised. The principle here is to assume your assets are already compromised and check the asset for integrity violation compared to a known-good state. This allows for a more focused investigation of potential malicious activity.

Reduction in time to detect a breach

With cyber threat hunting being a proactive and ongoing approach, and focusing on suspicious network activity and asset integrity; the process can greatly reduce the time it takes to identify a breach that already occurred. It is also possible to identify ongoing attempts of an adversary to further establish a persistent foothold in your network infrastructure.

In-depth information of network communication between systems

One critical component of cyber threat hunting is the understanding of the network traffic flow. Is data entering the network or is data leaving the network? Combining netflow data and other data sources with visualization and data analytics allow the threat hunter to quickly identify a potential risk to the organization.

Contextual awareness of communication patterns and protocols

By taking the vast amounts of meta-data available across multiple security data sets, cyber threat hunting tools and processes create a contextual awareness of the corporate infrastructure. Additionally, it allows the threat hunter to draw from historic data to see if anomalies suddenly appear that are out of the expected traffic pattern.

Characteristics of Cyber Threat Hunting

Human-driven approach

A key ingredient for successful cyber threat hunting is the fact that it is “powered by a human”. Why is it important? It is because the adversary is also human and the tools being used during an intrusion were written by humans and leave distinctive patterns behind.  The human aspect of cyber threat hunting builds upon intuition, hypotheses and experience. Those are important elements for a successful threat hunting experience.

Threat Intelligence feed correlation

With the overwhelming number of cyber threats out there it would be impossible for a human to keep track of them all. This is where threat intelligence feed correlation becomes a critical component. The ability to aggregate and overlay multiple different threat feeds allows the threat hunter to quickly identify and categorize potential threats to the organization.

Behavioral analysis

Identifying network activities or communications which fall outside the norm is a very useful way to identify potential indicator of compromises (IOC). Drawing from historic data points of network flow data, it is possible to identify patterns command & control beacons or data exfiltration activity.
