In IoT networks, what is the main purpose of using network segmentation?
- Improving data transfer speed
- Increasing device power consumption
- Isolating different segments of the network
- Simplifying network configuration
Network segmentation in IoT serves the main purpose of isolating different segments of the network. By doing so, potential security breaches in one segment are contained, preventing lateral movement of attackers. This enhances the overall security of the IoT ecosystem by limiting the impact of security incidents. Understanding the role of network segmentation is crucial for designing resilient and secure IoT networks.__________________________________________________
What distinguishes a 'false positive' from a 'true positive' in the context of security incident detection?
- A 'false positive' is a benign event incorrectly identified as a threat
- A 'false positive' is an actual security incident
- A 'true positive' is a genuine security incident accurately detected
- A 'true positive' is a harmless event incorrectly identified as a threat
In the context of security incident detection, a 'false positive' occurs when a security tool incorrectly flags a benign event as a threat. On the other hand, a 'true positive' represents an accurate detection of a genuine security incident. Distinguishing between these terms is vital for refining incident response processes and reducing unnecessary alerts, ensuring efficient and accurate threat detection.__________________________________________________
In quantum cryptography, the ____________ principle ensures that the act of measuring a quantum system inevitably alters its state.
- Complementarity Principle
- Heisenberg Uncertainty Principle
- Observer Effect
- Pauli Exclusion Principle
The Heisenberg Uncertainty Principle states that the more precisely the position of a quantum particle is known, the less precisely its momentum can be known, and vice versa. This principle has implications for quantum cryptography, where the act of measuring a quantum system inevitably disturbs its state, introducing challenges and considerations in secure communication.__________________________________________________
During an investigation of a data breach, forensic experts found evidence of data exfiltration through an encrypted channel. This scenario primarily involves the technique of ____________.
