Network-Based IDS (NIDS)/Network-Based IPS (NIPS)
Network-Based IDS (NIDS)/Network-Based IPS (NIPS): Network-Based Intrusion Detection Systems (NIDS) are security solutions that monitor network traffic to detect suspicious activity and potential security breaches. Upon detection, NIDS generates alerts for further investigation. Network-based intrusion Prevention Systems (NIPS) go a step further by actively blocking or mitigating the detected threats in real time, often integrating […]
NIST Forensic process – Analysis
NIST Forensic process – Analysis: Analysis is a crucial stage in the National Institute of Standards and Technology (NIST) Forensic Process. This phase involves the in-depth evaluation and interpretation of the data that has been examined to arrive at useful insights. It seeks to answer the who, what, where, when, why, and how of an […]
NIST Forensic process – Collection
NIST Forensic process – Collection: Collection is a key stage in the NIST Forensic Process, which involves gathering relevant digital evidence from various sources, like hard drives, network logs, system memory, etc. This stage must be done in a systematic, careful, and legally acceptable manner to ensure the integrity and admissibility of the evidence in […]
NIST Forensic process – Examination
NIST Forensic process – Examination: Examination in the NIST Forensic Process is the systematic review of digital evidence using both automated and manual methods. The goal of this phase is to extract and identify relevant information from the collected data without altering the evidence. This process can involve the use of specialized software and may […]
NIST Forensic process – Reporting
NIST Forensic process – Reporting: Reporting is the final phase in the NIST Forensic Process, where the findings from the analysis stage are documented in a clear, comprehensive, and accessible manner. This report is expected to present the evidence, methodology, and conclusions in a way that can be understood by both technical and non-technical audiences, […]
Nonce
Nonce: A randomly or pseudo-randomly generated number that is used only once in a communication protocol. They are often employed to ensure data freshness and to prevent replay attacks where an attacker might attempt to replay a previous communication or transaction, leading to potential data breaches or fraudulent transactions.
