DarkMarketA DarkMarket is a form of underground marketplace that exists on the dark web, where users can purchase illicit goods and services and remain anonymous. Traders on dark markets typically use virtual currencies and other financial methods that make their transactions untraceable. Also called a dark web black market. | |
Data BreachUnauthorized access or acquisition of sensitive information. Digital investigations into breaches often focus on intrusion vector, affected systems, exfiltration evidence, notification requirements, and correlating attacker infrastructure and artifacts across endpoints and logs. | |
Data IntegrityThe assurance that data remains accurate, consistent, and unaltered except by authorized processes. Integrity is often verified using hashing, checksums, and journaling. | |
Data LifecycleThe stages data goes through from creation and active use to archival and deletion. Effective lifecycle management supports compliance, security, and storage efficiency. | |
Data MinimizationCollecting only the data necessary to meet investigative objectives and legal scope. In digital cases, minimization reduces privacy impact and helps prevent over-collection, especially when searching large accounts or cloud datasets. | |
Data RedundancyThe duplication of data to improve reliability and fault tolerance. Techniques include RAID configurations, backups, and replication. | |
Data TypeA classification that describes what kind of value a variable can hold and what operations are valid (e.g., integer, float, string, boolean, array, dictionary). Some languages enforce types strictly, while others are more flexible. | |
Data written to HDDsAn analog hard disk drive (HDD) is a type of storage device that uses a spinning disk to store data. The data is written to the disk using a magnetic head, which reads and writes data to the surface of the disk. There are three main methods of writing data to an analog HDD: longitudinal recording, perpendicular recording, and shingle recording.
Overall, the method of writing data to an analog HDD can have a significant impact on the capacity and performance of the device. Perpendicular recording and shingle recording allow for higher data density and capacity, but may also be more complex and require more advanced technology. | ||
Data written to SSDsSolid-state drives (SSDs) are a type of storage device that use non-volatile memory to store data. Unlike traditional hard drives, which use spinning disks to store data, SSDs do not have any moving parts and are therefore faster and more durable. However, SSDs have some limitations compared to hard drives, particularly in terms of write endurance and wear leveling. In order to maximize the lifespan of an SSD and ensure that it performs optimally, it is important to understand how data is written to an SSD and how these limitations are addressed. Write endurance refers to the number of times that data can be written to and erased from an SSD before it begins to degrade. SSDs have a finite number of write cycles, and if they are exceeded, the performance of the SSD can begin to degrade. In order to address this issue, SSDs use a process called wear leveling, which evenly distributes writes across the entire drive in order to prevent any one area from being written to excessively. This helps to extend the lifespan of the SSD by ensuring that all areas of the drive are used evenly. Another factor that affects the performance of an SSD is the type of non-volatile memory used to store data. SSDs use either single-level cell (SLC) or multi-level cell (MLC) memory, with SLC being faster and more durable but also more expensive. SLC memory stores one bit of data per cell, while MLC memory stores two or more bits per cell. This allows MLC memory to store more data in a smaller space, but it also results in slower write speeds and a lower write endurance compared to SLC memory. In conclusion, data is written to an SSD by storing it in non-volatile memory cells, which can be either SLC or MLC. In order to extend the lifespan of the SSD and ensure optimal performance, the write endurance of the drive is managed through wear leveling, which evenly distributes writes across the drive. The type of memory used in the SSD, SLC or MLC, can also impact the performance of the drive. | |
