Automated summary
Helps secure backend applications by implementing authentication, encryption, vulnerability scanning, and compliance checks against OWASP threats.
Strengths
- Comprehensive coverage of OWASP Top 10 with concrete code examples
- Integration with scanning tools (SAST, DAST, SCA) and secret detection
- Support for compliance frameworks (GDPR, HIPAA, PCI-DSS, SOC2)
- Code examples for authentication, SQL injection prevention, and security headers
Limitations
- Focuses on code-level security, not infrastructure or network
- May require additional configuration for specific environments
- Limited to backend applications as described
When building or auditing backend code for security vulnerabilities, implementing authentication/encryption, or preparing for compliance audits.
For frontend security, network security, or non-software security assessments.

Examples
Example 1: Secure Authentication
from fastapi import Depends, HTTPException
from fastapi.security import OAuth2PasswordBearer
from passlib.context import CryptContext
from jose import jwt
import secrets
pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")
oauth2_scheme = OAuth2PasswordBearer(tokenUrl="token")
def hash_password(password: str) -> str:
return pwd_context.hash(password)
def verify_password(plain: str, hashed: str) -> bool:
return pwd_context.verify(plain, hashed)
def create_token(user_id: str) -> str:
return jwt.encode(
{"sub": user_id, "jti": secrets.token_urlsafe(16)},
SECRET_KEY,
algorithm="HS256"
)
Example 2: SQL Injection Prevention
# BAD - Vulnerable to SQL injection
def get_user_bad(user_id: str):
query = f"SELECT * FROM users WHERE id = '{user_id}'"
return db.execute(query)
# GOOD - Parameterized query
def get_user_good(user_id: str):
query = "SELECT * FROM users WHERE id = :id"
return db.execute(query, {"id": user_id})
Example 3: Security Headers
from fastapi import FastAPI
from starlette.middleware.base import BaseHTTPMiddleware
class SecurityHeadersMiddleware(BaseHTTPMiddleware):
async def dispatch(self, request, call_next):
response = await call_next(request)
response.headers["X-Content-Type-Options"] = "nosniff"
response.headers["X-Frame-Options"] = "DENY"
response.headers["X-XSS-Protection"] = "1; mode=block"
response.headers["Strict-Transport-Security"] = "max-age=31536000"
response.headers["Content-Security-Policy"] = "default-src 'self'"
return response
app = FastAPI()
app.add_middleware(SecurityHeadersMiddleware)
Compliance Checklists
GDPR
- [ ] Lawful basis for processing
- [ ] Data minimization
- [ ] Right to access/deletion
- [ ] Breach notification (72h)
- [ ] DPO if required
PCI-DSS
- [ ] Encrypt cardholder data
- [ ] No CVV storage
- [ ] Access controls
- [ ] Regular testing
- [ ] Audit logging
Troubleshooting
Common Issues
| Issue | Cause | Solution | |-------|-------|----------| | Token expired | Short TTL | Implement refresh tokens | | CORS blocked | Missing headers | Configure CORS properly | | Weak encryption | Old algorithms | Use AES-256, RSA-2048+ | | SQL injection | String concat | Use parameterized queries |

Resources
From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/backend-application-security-mm8o52be/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/backend-application-security-mm8o52be' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/backend-application-security-mm8o52be/download' --output '.skill-downloads/backend-application-security-mm8o52be/SKILL.md.part' && mv '.skill-downloads/backend-application-security-mm8o52be/SKILL.md.part' '.skill-downloads/backend-application-security-mm8o52be/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

test -f '.skill-downloads/backend-application-security-mm8o52be/SKILL.md' && test -s '.skill-downloads/backend-application-security-mm8o52be/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/security' && cp -R '.skill-downloads/backend-application-security-mm8o52be' '.claude/skills/security'Cursor

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.
Official OpenSkills installationopenskills install './.skill-downloads/backend-application-security-mm8o52be'openskills read 'backend-application-security-mm8o52be'Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.
For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/backend-application-security-mm8o52be/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
