What it does

Implementing Just In Time Access Provisioning is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Implements Just-In-Time (JIT) access provisioning to eliminate standing privileges by granting temporary, time-bound access, covering approval workflows, automatic expiration/revocation, and PAM/IGA integration. Use when designing access approval workflows or replacing standing privileged accounts with time-bound, zero-trust-aligned grants.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts, reference files and assets (for example `assets/template.md`, `references/api-reference.md` and `references/standards.md`).

It sits in Security. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.

When your agent uses it

  • Designing access approval workflows
  • Replacing standing privileged accounts with time-bound
  • Zero-trust-aligned grants

Example prompts

  • “Use the implementing-just-in-time-access-provisioning skill to implement Just-In-Time (JIT) access provisioning to eliminate standing privileges by…”
  • “/implementing-just-in-time-access-provisioning”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Identify Eligible Access Types
  2. Design Approval Workflows
  3. Implement Time-Bound Access
  4. Integration Architecture
  5. Monitoring and Compliance

What it can do on your machine

Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Implementing Just In Time Access Provisioning loads about 1.3k tokens when it runs, and up to ~2.6k if it reads all its reference files. Until then it costs about 97 tokens; SKILL.md has 551 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~97
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Implementing Just-In-Time Access Provisioning

Overview

Implement Just-In-Time (JIT) access provisioning to eliminate standing privileges by granting temporary, time-bound access only when needed. This skill covers JIT architecture design, approval workflows, automatic expiration, integration with PAM and IGA platforms, and alignment with zero trust principles.

When to Use

  • When deploying or configuring implementing just in time access provisioning capabilities in your environment
  • When establishing security controls aligned to compliance requirements
  • When building or improving security architecture for this domain
  • When conducting security assessments that require this implementation

Prerequisites

  • Familiarity with identity access management concepts and tools
  • Access to a test or lab environment for safe execution
  • Python 3.8+ with required dependencies installed
  • Appropriate authorization for any testing activities

Objectives

  • Design JIT access request and approval workflows
  • Implement time-bound access grants with automatic expiration
  • Configure risk-based approval routing (auto-approve low-risk, multi-approval for high-risk)
  • Integrate JIT with PAM for privileged access elevation
  • Monitor and audit all JIT access grants and usage
  • Reduce attack surface by eliminating standing privileges

Key Concepts

JIT Access Models
  1. Broker and Remove: Grant access through approval, auto-remove after time window
  2. Elevation on Demand: User has base access, elevates to privileged upon request
  3. Account Creation/Deletion: Temporary account created, destroyed after use
  4. Group Membership Toggle: Add to privileged group temporarily, auto-remove
Zero Standing Privilege (ZSP) Principle
  • No user has permanent privileged access
  • All privileged access requires explicit request with business justification
  • Access automatically expires after defined time window
  • All access events logged and auditable

Workflow

Step 1: Identify Eligible Access Types
  • Privileged admin access (domain admin, root, DBA)
  • Production environment access
  • Sensitive data access (PII, financial, healthcare)
  • Emergency/break-glass access
  • Third-party vendor access
Step 2: Design Approval Workflows
  • Self-service request portal with justification requirement
  • Auto-approve for pre-authorized low-risk access (< 1 hour)
  • Single approver for medium-risk (manager or resource owner)
  • Dual approval for high-risk (manager + security team)
  • Emergency bypass with post-facto review
Show full SKILL.md (238 more words)Show less
Step 3: Implement Time-Bound Access
  • Configure maximum access duration per resource type
  • Implement countdown timer with extension request capability
  • Auto-revoke at expiration regardless of session state
  • Grace period notification (15 min before expiry)
  • Automatic session termination on access expiry
Step 4: Integration Architecture
  • Connect to IAM/IGA platform for provisioning/de-provisioning
  • Integrate with PAM for privileged credential checkout
  • Connect to ITSM for ticket correlation
  • Forward events to SIEM for monitoring
  • API integration for programmatic access requests
Step 5: Monitoring and Compliance
  • Log all JIT requests, approvals, grants, and revocations
  • Alert on access used beyond approved scope
  • Track access not used (request but never connected)
  • Measure mean time to access (request to grant)
  • Report on access patterns for baseline optimization

Temporary AccessAC-2(2)Automated temporary account management
Least PrivilegeAC-6Time-bound minimum access
Access EnforcementAC-3Automated access grant/revoke
AuditAU-3Complete JIT access audit trail
Risk AssessmentRA-3Risk-based approval routing

Common Pitfalls

  • Setting time windows too long, negating JIT benefits
  • Not implementing automatic revocation at expiration
  • Complex approval workflows causing access delays for legitimate needs
  • Not providing emergency bypass for critical incidents
  • Failing to audit approved but unused JIT access

Verification

  • JIT request workflow functional end-to-end
  • Access automatically revoked at expiration
  • Approval routing correct for all risk levels
  • Emergency access bypass works with post-review
  • All JIT events logged to SIEM
  • Standing privileges reduced by measurable percentage
  • Mean time to access meets business SLA
