cloud-network-security

A tool for managing network access rules for Elastic Cloud Serverless projects. These rules can allow specific IP addresses or restrict traffic to AWS PrivateLink VPC endpoints.

In plain words
What is it for?
Use it to create, change, or remove IP and VPC traffic filters.
Why use it?
It helps prevent unwanted network access and control which private connections can reach a project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cloud-network-security scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/cloud_network_security.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Cloud Network Security

Manage network security policies for Elastic Cloud Serverless projects: IP filters to allowlist specific IPs or CIDRs, and VPC filters (AWS PrivateLink) to restrict traffic to specific VPC endpoints.

Prerequisite: This skill assumes the cloud-setup skill has already run — EC_API_KEY is set in the environment and the organization context is established. If EC_API_KEY is missing, instruct the agent to invoke cloud-setup first. Do NOT prompt the user for an API key directly.

For project creation and day-2 operations (including associating filters with projects), see cloud-create-project and cloud-manage-project. For identity and access management (users, roles, API keys), see cloud-access-management.

For detailed API endpoints and request schemas, see references/api-reference.md.

Terminology

This skill uses network security as the umbrella term, aligned with the Elastic Cloud UI direction. The underlying API uses traffic filters — you will see traffic-filters in endpoint paths and traffic_filters in JSON fields. When a user or agent says "traffic filter," they mean the same thing as "network security policy." The two filter types are IP filters (type ip) and VPC filters (type vpce).

Jobs to Be Done

  • Create an IP filter to restrict ingress to specific IPs or CIDR blocks
  • Create a VPC filter (AWS PrivateLink) to restrict traffic to specific VPC endpoint IDs
  • List, inspect, update, and delete network security policies
  • Look up PrivateLink region metadata (service names, domain names, availability zones)
  • Associate or disassociate filters with Serverless projects (delegates to cloud-manage-project)
  • Audit the current network security posture for an organization

Prerequisites and permissions

Item Description
EC_API_KEY Cloud API key (set by cloud-setup). Required for all operations.
Region Filters are region-scoped. The user must specify the target region when creating filters.
Project IDs Required only when associating filters with projects (handled by cloud-manage-project).

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
