Comprehensive Security Practices and Vulnerability Mitigation at Laiye Technology

Security is a non‑negotiable requirement for any profitable system; attackers constantly seek vulnerabilities, and in 2020, 46% of enterprises suffered attacks due to unpatched flaws.

Laiye Technology, an RPA + AI company, launched a comprehensive security program in Q3 2022, first cataloguing known issues and then addressing them from both application and infrastructure perspectives.

Application‑Level Controls

Weak Password Remediation : Password length must be ≥8 characters, include upper‑case, lower‑case, digits, and special symbols, and require the old password for resets. Existing weak passwords are identified by comparing password‑creation timestamps with the policy enforcement date, then users are prompted to change them. All passwords are stored with per‑user salts and encrypted.

Brute‑Force Protection : Implemented human‑verification (CAPTCHA), rate‑limiting via token‑bucket algorithms, account lockout after repeated failures, and cloud‑based anti‑brute‑force services.

SQL Injection Mitigation : All database access now uses an ORM that employs prepared statements. Example of Go’s driver preparation function:

func ctxDriverPrepare(ctx context.Context, ci driver.Conn, query string) (driver.Stmt, error) {
if ciCtx, is := ci.(driver.ConnPrepareContext); is {
return ciCtx.PrepareContext(ctx, query)
}
si, err := ci.Prepare(query)
if err == nil {
select {
default:
case <-ctx.Done():
si.Close()
return nil, ctx.Err()
}
}
return si, err
}

Prepared statements parse the SQL into a syntax tree, ensuring user input is treated only as data, not executable code.

XSS Prevention : Classified XSS into reflected, stored, and DOM‑based types; applied content filtering, CSP headers, and strict use of dangerouslySetInnerHTML with ESLint warnings in React projects.

CSRF Defense : Enforced same‑origin checks, issued CSRF tokens on the first authenticated response, stored them in meta tags or WebStorage, and required them on subsequent state‑changing requests. Token rotation and validation are performed server‑side.

Secure File Upload : Enforced whitelist of file types, validated file signatures, renamed files, limited name length and size, and required signed upload URLs with minimal permissions and short expiry.

Privilege Controls

Vertical (Function) Privilege : All API calls are authenticated; UI routes are generated server‑side to prevent unauthorized page rendering.

Horizontal (Data) Privilege : Each robot receives a unique hash; middleware checks the hash against the logged‑in user before allowing operations. Global hashes and GraphQL custom scalars encrypt IDs to prevent enumeration.

Example GraphQL scalar for ID conversion:

const { GraphQLScalarType, Kind } = require('graphql')
const IDScalar = new GraphQLScalarType({
name: 'ID Scalar',
description: 'ID type conversion: server number ↔ client string',
serialize(value) { return number2string(value) },
parseValue(value) { return string2number(value) },
parseLiteral(ast) { if (ast.kind === Kind.STRING) return string2number(ast.value); return 0 }
})

Code Security Review

Since Q4 2022, every push triggers automated security linting that checks for hard‑coded secrets, raw SQL usage, vulnerable dependencies, insecure cookie flags, and other unsafe patterns. Violations block the push and require history cleaning.

Infrastructure Hardening

Laiye employs NSFocus for regular vulnerability scans of OS, middleware, and containers, scanning after each vulnerability‑database update, server or middleware addition, and version change. Detected issues are logged, patched, and rescanned until resolved.

Patching strategy includes selecting stable OS versions, scanning, fixing, and re‑scanning; maintaining patched Docker images for quick redeployment; and using scripted patches for in‑place upgrades when images cannot be used.

All findings are tagged by component, severity, impact scope, and restart requirement to prioritize remediation.

Overall Security Process

The security workflow integrates continuous training, secure development lifecycle (SDL), automated code reviews, regular penetration testing, IAST tooling, and plans for future measures such as honeypots and SRC.

Security truly has no small matters.
