The Threat Detection Gap in the Cloud

Recent research shows that only one out of three breaches are found or reported by a security teams’ internal teams or tools, with two out of three being either announced by a successful attacker or a third party. This same report shows that it saves organizations a substantial amount, in the event of a breach, when the attack is discovered internally. This data suggests that threat detection needs to be improved across the board.

There is nowhere that this is more true than in cloud environments, where 90% of teams stated their containerized or Kubernetes environments had been breached in the last year. 85% of CISOs recently named cloud security as their biggest challenge.

Section 1: Overview of Threat Detection Tools

What are Threat Detection Tools?

Threat detection tools are software programs created to detect and address possible cyber threats in cloud environments. These tools help maintain the security and reliability of cloud-based systems by monitoring suspicious behavior, finding weaknesses, and activating automated reactions to reduce risks. Threat detection tools are critical for safeguarding confidential information, upholding regulatory requirements, and preserving the confidence of clients.

Types of Threat Detection Tools

Behavioral Analysis, Utilizing Anomaly Detection & Machine Learning (ML) 

Behavioral analysis relies on machine learning and anomaly detection (through drift or other means) to identify unusual  patterns or behaviors. . Behavioral tools vary widely in their specific methodologies and focus. While some approaches rely on training with specific datasets (of known malware, or malicious network traffic for example) to be able to identify attacks , others focus much more broadly on context across a set of attack vectors (e.g. application or identity context for a Next Generation Firewall). Yet another group will focus on baselining acceptable behavior and identifying drift from that behavior.  By continuously learning from new data, these tools can adapt to evolving threats and provide real-time alerts for suspicious activities. The key benefits of behavioral analysis include:

  • Built-in Context: By definition, a behavioral approach looks at various pieces of context to determine what normal and anomalous look like. This can dramatically reduce the time involved in identifying the  details of an attack.
  •  Identifying Novel Attacks: This technique can detect novel attacks as they happen, as opposed to only detecting a known threat.
  • Adaptability: Continuously improves its accuracy by learning from new data or updating an organization’s baseline behavior to keep false positives low.
  • Reduce false positives: : Behavioral methods should reduce false positives because they are constantly adjusting, and include context. 


Signature-Based Detection Tools

Signature-based detection tools utilize predefined patterns or signatures of known threats, offering quick identification and reliable protection against well-documented malicious activities. 

These patterns are derived from previous malicious activities, such as specific IP addresses, file hashes, or behaviors associated with malware. When a new activity matches a known signature, the tool flags it as a potential threat. 

This method is effective for identifying well-known threats but may be less effective against new or unknown attacks. 

The main advantages of signature-based detection are:

  • Quick response decisions: If you’re detecting a threat that is known, like a cryptominer, there is little risk in allowing the same tool to block the malicious traffic or activity.
  • Quick identification: Quickly identifies threats based on established patterns and, because they are known threats, it’s possible to get quickly up to speed on the issue and what action to take.
  • Measurable results: The efficacy of a signature-based tool (for blocking known threats only) can sometimes be relatively easily measured by the number of rules in its library, the number of exploit avenues those rules cover, or the number of security engineers behind the rules in a library.

Section 2: Key Threat Detection Tool Features


Though observability is generally deemed relevant for performance, it is an essential tool for advanced threat detection. For example, many cryptominers can be identified simply by the increased costs associated with their activity in an environment.

Real-time monitoring is integral to an advanced threat detection strategy because it ensures immediate identification of potential threats and reduced response time.

This capability involves collecting and analyzing data from sources such as network traffic, system logs, and user activities in real-time versus from APIs that have built-in lags (for example from cloud providers). 

For example, in the case of Kubernetes Security Posture Management, static scanning generally will not help with threat detection, it will help with posture and hardening. Real-time KSPM though, will show the current real-time situation and any associated alerts, so it is an essential part of threat detection in a Kubernetes environment. 


  • Immediate Identification of Potential Threats: Real-time monitoring ensures that threats are identified near-instantly, allowing prompt action before they can worsen.
  • Confirmation of Posture in Real-Time: Real-time monitoring, for example of cloud or Kubernetes posture, can determine whether the posture that was intended is, in fact, the current posture, identifying key areas of weakness and places where attackers have gotten through even in hardened environments.
  • Reduced Response Time: Continuous monitoring supports faster detection, and therefore response, minimizing the window of opportunity for attackers to cause harm.
  • Enhanced Visibility: Provides comprehensive visibility into the security posture of the cloud environment, helping security teams understand and respond to malicious activities. 


Automated Response 

Threat detection tools with automated response capabilities enable mitigation without manual intervention. These tools can execute predefined actions, such as isolating compromised systems, blocking malicious IP addresses, and initiating data backup processes. 


  • Swift Action: Automated responses are executed immediately
  • Minimal Human Intervention: Reduces the need for manual involvement, freeing up security personnel to focus on more complex tasks 
  • Reduced Damage: Quick and automated responses limit the extent of damage that threats can cause


Threat Intelligence Feeds

Threat intelligence feeds provide real-time information on emerging threats and vulnerabilities. These feeds aggregate data from various sources, including security research organizations, industry reports, and global threat databases. By integrating threat intelligence feeds, detection tools can stay up-to-date with the latest threat landscape, enabling proactive defense measures.


  • Address a Broadening Threat Landscape: Access to current threat intelligence allows organizations to address a broader scope of threats than a single research team could do on its own. The measuring and reporting systems for CVEs and other threats differ across the world so having access to various sources means a larger variety of bases can be covered. 
  • Informed Decision-Making: Up-to-date threat information enhances decision-making by providing broad context and insights 
  • Improved Accuracy: Threat intelligence feeds correlate local findings with global threat data, reducing false positives


By including these features in your threat detection toolkit, you can achieve comprehensive protection in your cloud environment.

The Role of Threat Detection and Response for the Cloud in Compliance Requirements, Cyber Insurance, and New SEC Requirements

Today, threat detection and response is a requirement across the board from a compliance and regulations perspective, and can even make your cyber insurance cheaper.

In the case of the SEC, security teams in the USA are now subject to regulations requiring periodic disclosures of how they do detection & response, among other things. The SEC requirement states, “Specifically, we are adopting amendments to require current disclosure about material cybersecurity incidents.  We are also adopting rules requiring periodic disclosures about a registrant’s processes to assess, identify, and manage material cybersecurity risks, management’s role in assessing and managing material cybersecurity risks, and the board of directors’ oversight of cybersecurity risks.”

Compliance regulations like SOX, SOC2, HIPAA and PCI requirements all include specific requirements around threat detection and response, though some regulations are more explicit than others about the methods required to achieve the basic goals of integrity and responsible reporting. 

In the case of cyber insurance, the premiums will depend on an organization’s general level of risk which is impacted by its size and its overall posture, as well as the controls that are in place. In the case of detection and response, and incident response plan is a simple document that can be shared with a cyber insurance provider, as one of the few concrete documents that prove there is a plan for resilience in the event of a successful attack. Threat detection and response is a critical part of making that plan a reality, and showing to the insurers that your plan has some teeth.

How Rad Security Helps with Threat Detection and Response

RAD Security detects threats with behavioral cloud native detection and response. By snapshotting a clean representation of normal behavior, RAD can compare new runtime activity against a fingerprint to detect abnormal behavior:

  • Is this process, program, file, or network activity expected based on the behavior that's been represented in the fingerprint?
  • Does the node appear at the expected location in the hierarchy? 
  • Do the node's properties match the expected properties?  Is this process executed by the expected user?  Is the expected file activity opening the expected file?

Inverting the model--from writing rules to identify suspected bad behavior, to instead flagging activity that deviates from the norm--greatly simplifies and improves detection capabilities. 

This exception-based security model means that novel attacks become immediately apparent, as they diverge from the expected behavior of the app.  No new signatures need to be written, and there's no lag in detection. Immediately, we can also see that the fingerprint-based analysis can take into account not just the properties of the activity (which is the status quo for runtime activity today), but also context, relationships with other activity, and a stateful knowledge of what activity should be expected in relation to other activity. 

RAD security behavioral method vs other container runtime security methods

Compared to the signature-based approach, the RAD standard is less noisy, more accurate and stateful, including context by definition.

Here is an example of drift through the RAD Security platform, in this case, an nginx container running with an established baseline and drift that includes a remote shell.
