aws-security

aws-security is a skill for Claude Code, Codex from eliecer2000/kiro-bootstrap. It costs 30 tokens per session (1,956 once invoked), scanned A, original, MIT.

A guide for securing applications and infrastructure on AWS, Amazon's cloud platform.

In plain words
What is it for?
It helps configure access rules, secret storage, encryption, network protections, service hardening, and security auditing.
Why use it?
It helps reduce risks such as excessive permissions, exposed secrets, unencrypted data, unsafe networks, and missing security records.

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

aws-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 5d ago.

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.

AWS Security

Skill para implementar seguridad en workloads AWS: IAM least privilege, gestión de secretos, cifrado en tránsito y reposo, networking seguro, endurecimiento de servicios y auditoría de configuraciones.

Principios fundamentales

  • Least privilege siempre: cada componente tiene solo los permisos mínimos necesarios para funcionar.
  • Defense in depth: múltiples capas de seguridad. No depender de un solo control.
  • Cifrado por defecto: en tránsito (TLS 1.2+) y en reposo (KMS) para todo recurso que lo soporte.
  • Secretos nunca en código: usar SSM Parameter Store (SecureString) o Secrets Manager.
  • Auditoría continua: CloudTrail habilitado, Config rules activas, GuardDuty encendido.

IAM: Políticas de mínimo privilegio

Estructura de política IAM

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "AllowDynamoDBReadWrite",
      "Effect": "Allow",
      "Action": [
        "dynamodb:GetItem",
        "dynamodb:PutItem",
        "dynamodb:UpdateItem",
        "dynamodb:DeleteItem",
        "dynamodb:Query"
      ],
      "Resource": [
        "arn:aws:dynamodb:us-east-1:123456789012:table/orders",
        "arn:aws:dynamodb:us-east-1:123456789012:table/orders/index/*"
      ]
    }
  ]
}

Reglas de IAM

  • Nunca usar "Resource": "*" salvo para acciones que lo requieran (ej: sts:GetCallerIdentity, logs:CreateLogGroup).
  • Nunca usar "Action": "*". Listar acciones específicas.
  • Usar conditions cuando sea posible: aws:SourceArn, aws:PrincipalOrgID, aws:RequestedRegion.
  • Un rol IAM por Lambda. No compartir roles entre funciones con responsabilidades diferentes.
  • Preferir políticas inline en CDK/Terraform sobre políticas managed custom (más fácil de auditar).
  • Usar aws:PrincipalTag y ABAC para control de acceso basado en atributos en escenarios multi-tenant.

Ejemplo CDK: permisos mínimos

// ✅ Correcto: permisos específicos
table.grantReadWriteData(fn);
bucket.grantRead(fn);
queue.grantSendMessages(fn);

// ❌ Incorrecto: permisos excesivos
fn.addToRolePolicy(new iam.PolicyStatement({
  actions: ['dynamodb:*'],
  resources: ['*'],
}));

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.

aws-security is a skill published in the GitHub repository eliecer2000/kiro-bootstrap (9 stars, last pushed 5mo ago), licensed MIT. It adds 30 tokens to every session and 1,956 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
