Cyber threat hunting is a proactive cyber defence activity. It is "the process of proactively and iteratively searching through networks to detect and isolate advanced threats that evade existing security solutions."
OWASP pytm is a Pythonic framework for threat modeling and the first Threat-Model-as-Code tool: The system is first defined in Python using the elements and properties described in the pytm framework. Based on this definition, pytm can generate a Data Flow Diagram (DFD), a Sequence Diagram and most important of all, threats to the system.
Anomalies are detected in several ways, most often with artificial intelligence type techniques. Systems using artificial neural networks have been used to great effect. Another method is to define what normal usage of the system comprises using a strict mathematical model, and flag any deviation from this as an attack.
The STRIDE was initially created as part of the process of threat modeling. STRIDE is a model of threats, used to help reason and find threats to a system. It is used in conjunction with a model of the target system that can be constructed in parallel. This includes a full breakdown of processes, data stores, data flows, and trust boundaries. [5]
The report, released this week by Gladstone AI, flatly states that the most advanced AI systems could, in a worst case, “pose an extinction-level threat to the human species.”
For example, model extraction could be used to extract a proprietary stock trading model which the adversary could then use for their own financial benefit. In the extreme case, model extraction can lead to model stealing , which corresponds to extracting a sufficient amount of data from the model to enable the complete reconstruction of the model.
Modern SIEM platforms support not only detection, but response too. The response can be manual or automated including AI based response. For example automated response capabilities of the Singularity™ AI SIEM, including autonomous quarantine of malicious files and termination of harmful processes. It even rolls back changes performed by the ...
It was initially proposed for threat modeling but was abandoned when it was discovered that the ratings are not very consistent and are subject to debate. It was discontinued at Microsoft by 2008. [2] When a given threat is assessed using DREAD, each category is given a rating from 1 to 10. [3]
