**Stack:** Go

- Prevalence: 高 頻繁に悪用される
- Impact: クリティカル 6 件の重大度クリティカルなルール
- Prevention: 文書化済み 11 件の修正例

**OWASP:** Identification and Authentication Failures (A07:2021-Identification and Authentication Failures) - #7

## Description

Hard-coded credentials typically create a significant hole that allows an attacker to bypass the authentication that has been configured by the product administrator. This hole might be difficult for the system administrator to detect.

## Prevention

1 件の Shoulder 検出ルールに基づく Hardcoded Credentials の予防策。

### Go

Load secrets from environment variables or a secrets manager instead of hardcoding

## Consequences

- 権限の取得
- 保護メカニズムの回避

## Mitigations

- 資格情報はソースコードの外に保管する
- 環境変数または安全な資格情報ストアを使用する
- 適切な鍵管理手順を実装する

## Detection

- Total rules: 11
- Critical: 6
- Languages: python, dockerfile, go, javascript, typescript, yaml

## Rules by Language

### Go (1 rules)

- **Hardcoded Secrets in Source Code** [CRITICAL]: API keys, passwords, or tokens hardcoded in source code.
  - Remediation: Load secrets from environment variables instead of hardcoding them.

```go
import "os"

apiKey := os.Getenv("API_KEY")
if apiKey == "" {
    log.Fatal("API_KEY not set")
}
```
