Reference
Cybersecurity glossary.
The terminology behind preemptive security and network hiding. Each term carries a definition and how LayerV implements the concept.
Agent Skill
An agent skill is a folder holding a SKILL.md file that a coding agent loads when a task matches the skill’s description.
Attack Surface Reduction
Attack surface reduction limits the entry points an attacker can reach, including exposed services, APIs, and administrative interfaces.
Capability URL
A capability URL carries its own access authority: whoever holds it can attempt to redeem it, within its expiry, use limits, and policy.
Certificate Transparency
Certificate Transparency is a set of public, append-only logs that record every TLS certificate a trusted authority issues.
Connector
A connector connects a private application to LayerV and carries authorized resource traffic over an outbound connection.
CRID (Cryptographic Resource ID)
A CRID is a stable identifier derived from a resource’s public key. The CRID of a private resource is safe to send to anyone; the CRID of a public resource opens that resource.
Default Deny Networking
Default deny networking blocks traffic unless an explicit policy permits it.
Dev Server Exposure
Dev server exposure is making a development server reachable beyond your machine, through a network binding or a public tunnel.
Localhost Tunnel
A localhost tunnel forwards traffic from an address on the internet to an app running on your own machine.
MCP Server
An MCP server exposes tools, data, and prompts to AI applications over the Model Context Protocol.
Micro-Authorized Access
Micro-authorized access describes an authorization limited to a particular resource and access window.
Mythos-Class AI
Mythos-class AI is terminology used here for advanced AI systems applied to reconnaissance, vulnerability discovery, and exploit development.
Network Hiding Protocol (NHP)
Network Hiding Protocol (NHP) describes authorizing access before opening a connection to a protected resource.
ngrok
ngrok is a tunneling service that gives an app on your machine a public URL through ngrok’s cloud.
OpenNHP
OpenNHP is an open-source implementation of network hiding, licensed under Apache 2.0.
Preemptive Cybersecurity
Preemptive cybersecurity aims to reduce opportunities for attack before an incident occurs.
Preview Deployment
A preview deployment is a copy of an app built from a branch or commit and hosted at its own URL so others can review it.
Publish
Publishing registers a resource with LayerV so its owner can issue access links.
Quick Tunnel
A quick tunnel is a temporary localhost tunnel started with one command and no account, usually on a random public hostname.
qURL
A qURL access link grants access to one resource published through LayerV, subject to the link’s expiry, use limits, and policy.
Share
Sharing issues an access link for a resource that you are authorized to manage.
Single Packet Authorization (SPA)
Single Packet Authorization (SPA) uses an authenticated packet to request access before a protected connection is allowed.
Single-Use Link
A single-use link permits one successful redemption and cannot be redeemed again afterward.
Software-Defined Perimeter (SDP)
A Software-Defined Perimeter (SDP) separates authorization from access to a protected resource.
Tunnel Interstitial
A tunnel interstitial is a warning page a tunnel service shows visitors before passing them through to the shared app.
Vibe Coding
Vibe coding is building software by describing what you want to an AI coding agent and letting it write the code.
Zero Trust Architecture
Zero Trust Architecture evaluates access to resources without trusting a user or device solely because of its network location.
