A key–value database, or key–value store, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, and a data structure more commonly known today as a dictionary or hash table. Dictionaries contain a collection of objects, or records, which in turn have many different fields within them, each containing ...
Sophos Ltd. is a British security software and hardware company. It develops and markets managed security services and cybersecurity software and hardware, such as managed detection and response, incident response and endpoint security software. [ 4][ 5] Sophos was listed on the London Stock Exchange until it was acquired by Thoma Bravo in ...
Endpoint security management is a software approach that helps to identify and manage the users' computer and data access over a corporate network. [3] This allows the network administrator to restrict the use of sensitive data as well as certain website access to specific users, to maintain, and comply with the organization's policies and standards.
The Online Certificate Status Protocol ( OCSP) is an Internet protocol used for obtaining the revocation status of an X.509 digital certificate. [ 2] It is described in RFC 6960 and is on the Internet standards track. It was created as an alternative to certificate revocation lists (CRL), specifically addressing certain problems associated with ...
Database index. A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure. Indexes are used to quickly locate data without having to search every row in a database table every time said table is accessed.
O (N) Space complexity. In computer science, the log-structured merge-tree (also known as LSM tree, or LSMT[ 1]) is a data structure with performance characteristics that make it attractive for providing indexed access to files with high insert volume, such as transactional log data. LSM trees, like other search trees, maintain key-value pairs.
An Ordered Key-Value Store (OKVS) is a type of data storage paradigm that can support multi-model database. An OKVS is an ordered mapping of bytes to bytes. It is a more powerful paradigm than Key-Value Store because OKVS allow to build higher level abstractions without the need to do full scans. An OKVS will keep the key-value pairs sorted by ...
Layering. Whole disk: Whether the whole physical disk or logical volume can be encrypted, including the partition tables and master boot record. Note that this does not imply that the encrypted disk can be used as the boot disk itself; refer to pre-boot authentication in the features comparison table.
