# Security Hardening
|
|
|
|
[中文](../zh-CN/security-hardening.md)
|
|
|
|
This checklist covers pre-production and continuous hardening for CyberStrikeAI.
|
|
|
|
## Before Going Live
|
|
|
|
- Change `auth.password` to a long random secret.
|
|
- Use HTTPS or a trusted reverse proxy.
|
|
- Restrict access by IP, VPN, or bastion.
|
|
- Enable `audit.enabled`.
|
|
- Set `c2.enabled: false` when C2 is not required.
|
|
- Do not expose standalone HTTP MCP without strong auth and network isolation.
|
|
- Connect only trusted external MCP services.
|
|
- Back up `config.yaml`, `data/`, and custom resource directories.
|
|
|
|
## Reverse Proxy Baseline
|
|
|
|
```nginx
|
|
client_max_body_size 200m;
|
|
proxy_buffering off;
|
|
proxy_http_version 1.1;
|
|
proxy_set_header Host $host;
|
|
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
|
proxy_set_header X-Forwarded-Proto https;
|
|
proxy_set_header Upgrade $http_upgrade;
|
|
proxy_set_header Connection "upgrade";
|
|
```
|
|
|
|
Recommended security headers:
|
|
|
|
```nginx
|
|
add_header X-Content-Type-Options nosniff;
|
|
add_header Referrer-Policy no-referrer;
|
|
add_header X-Frame-Options DENY;
|
|
```
|
|
|
|
## HITL Allowlist Baseline
|
|
|
|
Minimal allowlist:
|
|
|
|
```yaml
|
|
hitl:
|
|
tool_whitelist:
|
|
- read_file
|
|
- glob
|
|
- grep
|
|
- tool_search
|
|
```
|
|
|
|
Do not globally allowlist:
|
|
|
|
- `execute`;
|
|
- WebShell write/execute tools;
|
|
- C2 task/payload tools;
|
|
- high-risk external MCP tools;
|
|
- delete, write, upload, persistence tools.
|
|
|
|
## File Permissions
|
|
|
|
```bash
|
|
chmod 600 config.yaml
|
|
chmod 700 data
|
|
```
|
|
|
|
Run under a dedicated OS user. Avoid root unless explicitly required.
|
|
|
|
## External MCP Review
|
|
|
|
Before connecting:
|
|
|
|
- Can it execute commands?
|
|
- Can it read/write local files?
|
|
- Does it send data to third parties?
|
|
- Does it authenticate?
|
|
- Can output contain untrusted model/web content?
|
|
- Should it run in a container or separate user?
|
|
|
|
After connecting:
|
|
|
|
- keep high-risk tools out of allowlist;
|
|
- review tool list changes;
|
|
- audit config changes.
|
|
|
|
## C2 and WebShell
|
|
|
|
C2:
|
|
|
|
- disabled by default;
|
|
- enabled only during authorized window;
|
|
- listener ports separated from admin UI;
|
|
- cleanup payloads, sessions, tasks, and events.
|
|
|
|
WebShell:
|
|
|
|
- authorized targets only;
|
|
- clear naming;
|
|
- write/delete/execute requires approval;
|
|
- delete connections after project end.
|
|
|
|
## Retention
|
|
|
|
Suggested:
|
|
|
|
- audit: 30-90 days;
|
|
- monitor: 90-180 days;
|
|
- uploads: clean after project;
|
|
- C2/WebShell outputs: keep only report evidence;
|
|
- knowledge base: no real credentials or customer secrets.
|
|
|
|
## Periodic Review
|
|
|
|
Weekly:
|
|
|
|
- failed logins and unusual IPs;
|
|
- config changes;
|
|
- external MCP changes;
|
|
- long-running tools;
|
|
- unexpected C2 enablement;
|
|
- stale WebShell connections;
|
|
- disk and DB size.
|
|
|
|
Project closeout:
|
|
|
|
- clean temp workspaces;
|
|
- delete unnecessary uploads;
|
|
- archive evidence;
|
|
- delete stale WebShell/C2 resources;
|
|
- export audit records.
