What Is a Digital Twin?

Digital Twin Explainer A digital twin is a digital model of a real object, process, or system. It might represent one machine, a building, a delivery route, or an entire factory. The model is connected to measurements from the real thing so it can reflect how that thing is operating. Sensors, maintenance records, and operating data give the twin useful inputs. Engineers can compare expected behavior with current readings, spot…

What Is a Passkey?

Passkey Explainer A passkey is a sign-in credential that replaces a memorized password with a cryptographic key pair. Your device keeps the private key, while the website keeps the matching public key. The private key stays on the device rather than being sent to the website. When you sign in, the website asks the device to prove it holds the private key. Your phone, tablet, or computer unlocks that key…

How Does Endpoint Detection and Response Work?

Endpoint Detection and Response Explainer Endpoint detection and response, often called EDR, is security software that watches activity on laptops, desktops, servers, and other devices. It collects signals such as program launches, file changes, network connections, and sign-in activity so unusual behavior can be investigated. EDR looks for patterns that can suggest an attack, including suspicious processes, repeated failed sign-ins, unexpected changes to security settings, or a program trying to…

What Is Ransomware?

Ransomware Explainer Ransomware is malicious software used to block access to data or systems, usually by encrypting files. Attackers often demand payment in exchange for a decryption tool or for a promise not to release information they stole. It can reach an organization through a phishing message, an unpatched system, weak remote-access credentials, or software already on a compromised device. Once inside, an attacker may try to spread across connected…

How Does a Firewall Filter Traffic?

Firewall Explainer A firewall is a security control that decides which network traffic is allowed to pass between systems. It can run on a computer, a router, a dedicated security appliance, or a cloud service. Firewall rules often examine details such as the source and destination address, the network port, the protocol, and the connection’s state. A rule may allow routine web traffic, block an unneeded service, or limit access…

How Does Disaster Recovery Work?

Disaster Recovery Explainer Disaster recovery is the process of restoring systems, data, and services after a serious disruption. The disruption might be caused by a cyberattack, hardware failure, power problem, natural disaster, or a major mistake during a change. A recovery plan identifies the systems that matter most and sets goals for getting them back. The recovery time objective, or RTO, is the target for how quickly a service should…

What Is Data Loss Prevention?

Data Loss Prevention Explainer Data loss prevention, often shortened to DLP, is a set of tools and rules that help an organization keep sensitive information from being shared, copied, or stored in unsafe ways. It can cover email, cloud applications, web uploads, files, and removable devices. DLP systems look for information that needs protection. They may use labels applied by people, patterns such as account numbers, or rules that recognize…
