This approach strengthens your defenses, addressing risks before they can cause damage. This approach involves various types of threat hunting techniques that strengthen defenses, addressing risks before they can cause damage.

With 87% of companies using multi-cloud setups, cloud security is now a must-have. Reflecting this shift, over half of organizations, according to the SANS, have adopted structured threat-hunting methods-a big jump from 35% last year.

This guide covers all you need to know, from essential tools and techniques to overcoming challenges and building a stronger security posture.

What is Cloud Threat Hunting?

Cloud threat hunting is the ongoing process of detecting and remediating malicious activity in your cloud environment. Proactively looking for threats reduces the chances of successful attacks and improves overall security.

Good cloud threat hunting involves analyzing many different types of telemetry data, despite the difficulties of accessing cloud provider logs. Human expertise, advanced tools, and relevant data work together to find and stop threats that automated systems miss. Threat intelligence integration makes cyber threat hunting even better by providing cloud-specific tactics threat actors use.

What is Cloud Threat Hunting?

Cloud Environments and Threat Hunting

Cloud environments are a challenge for threat hunting because of their dynamic and ephemeral nature. Unlike traditional IT setups, cloud infrastructure is constantly changing, resources are spun up and down based on demand. This fluidity makes it hard for security teams to have a clear view of what's happening in their environment at any point in time. And without traditional network boundaries in cloud environments, it makes detection and response to threats even harder.

But this dynamic nature also presents opportunities for better threat hunting. Cloud providers offer a treasure trove of logging and monitoring data that can be used for threat detection. These logs provide detailed information on user activity, network traffic, and system events which is gold dust for identifying anomalies and potential threats. Cloud native security tools and services can automate many parts of threat detection and response so security teams can focus on the more complex threat hunting activities.

Good threat hunting in cloud environments requires a deep understanding of the cloud infrastructure and the ability to analyze large data. Security teams need to be able to identify patterns and anomalies in the data to detect threats. By using the logging capabilities and advanced security tools provided by cloud platforms, security teams can improve their threat detection and response capabilities and have a better security posture.

Threat Hunting in Cloud Environments Evolution

The threat landscape is changing so threat hunting in cloud environments must adapt to new tactics used by the bad guys. The multi-cloud environment has forced security teams to adapt their approach to the different tactics used by the attackers.

Threat actors use advanced techniques to evade traditional security controls so threat hunters must continually refine their detection methods. This evolution ensures cloud threat hunting stays relevant to the changing threats.

What to look for in a Cloud Threat Hunting Solution

A good cloud threat hunting solution must have several key attributes. First and foremost is scalability. The solution must be able to handle large amounts of data and scale with the organization, regardless of the size or complexity of the cloud infrastructure.

Real-time alerting is another must-have. The solution must provide real-time alerts and notifications when threats are detected so security teams can respond quickly and mitigate risks before they get out of hand.

Integration is also a must-have. The solution must integrate with other security tools and services such as SIEM systems and threat intelligence feeds. This integration provides a cohesive security strategy and improves the overall threat detection and response process.

Advanced analytics and machine learning are key to identifying threats and anomalies. These advanced analytics allow the solution to process and analyze large data sets quickly and find patterns that may indicate malicious activity.

Finally, the solution must be cloud-native, designed to use cloud-specific features and services. This means the solution can monitor and protect cloud infrastructure and applications provide visibility and detect and respond to threats in real time.

By having these attributes a cloud threat hunting solution can give security teams the tools and visibility they need to protect their cloud.

Cloud Threat Hunting Components

Several components are required for good cloud threat hunting. Tools that set baselines and investigate anomalies are important. Data (logs, network traffic, endpoint data, and threat intelligence feeds) is key to threat hunting. Active threat hunting in cloud security helps security teams find threats that automated tools miss.

Clear structure, defined roles, and a collaborative culture are required for threat hunting.

Real-Time Monitoring and Detection

Real-time monitoring of multiple telemetry sources including audit logs and user activity is required for cloud threat hunting. Analyzing telemetry in real time allows security teams to see deviations from baselines and recognize unusual patterns that may indicate malicious activity. Real-time monitoring means security teams can respond to security issues and mitigate threats as soon as they are detected.

Real-time monitoring allows security teams to respond to anomalies quickly, and reduce the attack window. Continuous monitoring and analysis of user activity and network traffic gives you visibility and control of the cloud so you can respond to abnormalities.

Advanced Analytics and AI/ML

Handling large amounts of data in cloud environments requires advanced analytics and machine learning (AI/ML) in cloud threat hunting. AI and ML help with threat detection by processing large data sets quickly and finding patterns that may indicate advanced threats.

Cloud-native User and Entity Behavior Analytics (UEBA) allows for behavioral analysis of patterns to detect threats.

Threat Intelligence

External threat intelligence feeds into the cloud threat hunting process giving threat hunters visibility into threats. These feeds provide current information on attacker tactics and trends so threat hunters can stay ahead of the threats.

Threat intelligence feeds help with threat detection and being proactive against advanced threats.

Security Teams Role in Cloud Threat Hunting

Security teams are the front-line defenders in cloud threat hunting. They are responsible for identifying threats and anomalies in the cloud and responding quickly to prevent attacks. To be effective they must have deep knowledge of the cloud infrastructure and be able to process large data sets.

Collaboration is key. Security teams must work with other departments such as IT and development to ensure cloud security is part of the overall security strategy. This ensures security is comprehensive and vulnerabilities are addressed quickly.

Cloud threat hunting requires a mix of humans and technology. While cloud-native security tools and services can automate many parts of threat detection and response, human analysts are required to interpret the data and make decisions. Security teams must be able to analyze data, recognize patterns, and understand the context of threats to respond.

Staying current with the latest threats and trends in cloud security is also important. Security teams should be trained and educated, attend industry events and conferences, and stay informed of emerging threats and best practices. This continuous learning ensures security teams can adapt their threat hunting to the changing threats.

In summary, security teams are the foundation of cloud threat hunting. Their skills, experience, and ability to use advanced tools and technologies are required to detect and respond to threats in cloud environments, and to have a strong security posture.

Real-life Cloud Threat Hunting

At Hunt.io, our research team has been hard at work, uncovering real-world tactics that illustrate the unique challenges of threat hunting in the cloud.

In this first example, detailed in our investigation titled "RunningRAT's Next Move: From Remote Access to Crypto Mining for Profit" we found that RunningRAT has shifted its focus from remote access to crypto mining by leveraging cloud-based open directories. By hosting malicious files within these directories, RunningRAT was able to keep command and control traffic low, avoiding detection triggers.
