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 […]
High-density equipment
High-density equipment: High-density equipment refers to hardware designed to maximize computing power or service capacity within a limited physical space. These systems are ideal for environments where space is at a premium, but demand for computational resources is high. Data centers, for instance, use high-density racks to house servers and storage devices efficiently.
Hijacking attacks
Hijacking attacks: A type of cyberattack in which an attacker takes control of a legitimate user’s session or network connection without the user’s knowledge or consent. This concept is used in the context of computer security to describe attacks that aim to steal sensitive information or gain unauthorized access to a system. Examples of hijacking […]
Hijacking
Hijacking: In cybersecurity, hijacking refers to various forms of unauthorized control over a computing resource, like taking over web sessions, diverting network traffic, or commandeering system functions. It often results in data breaches, service disruption, or facilitating further attacks such as spamming or phishing from a trusted source.
Hoax
Hoax: A deliberate deception or fabrication, often intended to trick or deceive others. It is commonly used in internet scams or fraudulent emails to lure victims into providing sensitive information or money. Examples include receiving an email claiming to be from a Nigerian prince offering a large sum of money in exchange for a small […]
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.
