High Availability
High Availability: The design and implementation of systems and processes to ensure that a service remains available at a high level over a defined period. This often involves redundancy, failover, load balancing, and other mechanisms to minimize downtime in the event of an outage or failure. From a security perspective, high availability is important not […]
Holistic redundancy
Holistic redundancy: Holistic redundancy refers to a comprehensive approach to backup and fault tolerance that encompasses not just data protection but also system and operational resilience. It involves various strategies like data replication, failover systems, and regular testing to ensure all critical components of an IT ecosystem can withstand disruptions.
General data center redundancy tier levels
General data center redundancy tier levels: The tier levels for data center redundancy, typically classified by the Uptime Institute, range from Tier I to Tier IV. Each tier reflects the complexity and redundancy of the data center’s infrastructure. Tier I represents the most basic level with no redundant components. Tier II includes some redundancy, Tier […]
Gray Box
Gray Box: Gray box testing is a hybrid approach to software testing that combines elements of both black box and white box testing methodologies. Testers have partial knowledge of the internal workings of the application, which allows them to design test cases with more efficiency. Gray box testing is ideal for situations where understanding the […]
Handshake
Handshake: In the context of networking, a handshake is a protocol or process used to establish a connection between two systems. A common example is the TCP three-way handshake, which involves a synchronization (SYN) message sent by the client to the server, an acknowledgment of the synchronization (SYN-ACK) sent by the server back to the […]
Forensics in the cloud
Forensics in the cloud: The application of digital forensics principles in a cloud computing environment. Due to the distributed nature of data in the cloud, standard forensic procedures may be adapted to accommodate specific cloud infrastructure characteristics, like multitenancy, data redundancy, and virtualization. It involves analyzing logs, recovering data, and investigating activities to reveal details […]
