🦀 TuskLang Rust Advanced Security

"We don't bow to any king" - Rust Edition

Master advanced security for TuskLang Rust applications. From mTLS to OPA, from secrets management to advanced authorization—build secure, compliant, and resilient systems with Rust and TuskLang.

🔒 Mutual TLS (mTLS)

mTLS with Rustls and Actix

use actix_web::{web, App, HttpServer, HttpResponse};
use rustls::{ServerConfig, Certificate, PrivateKey};
use std::fs::File;
use std::io::BufReader;
fn load_certs(path: &str) -> Vec<Certificate> {
    let certfile = File::open(path).unwrap();
    rustls_pemfile::certs(&mut BufReader::new(certfile)).unwrap()
        .into_iter().map(Certificate).collect()
}
fn load_key(path: &str) -> PrivateKey {
    let keyfile = File::open(path).unwrap();
    let keys = rustls_pemfile::pkcs8_private_keys(&mut BufReader::new(keyfile)).unwrap();
    PrivateKey(keys[0].clone())
}
#[actix_web::main]
async fn main() -> std::io::Result<()> {
    let certs = load_certs("cert.pem");
    let key = load_key("key.pem");
    let mut config = ServerConfig::builder()
        .with_safe_defaults()
        .with_no_client_auth()
        .with_single_cert(certs, key)
        .unwrap();
    HttpServer::new(|| App::new().route("/", web::get().to(|| HttpResponse::Ok().body("Hello, mTLS!"))))
        .bind_rustls("0.0.0.0:8443", config)?
        .run()
        .await
}

TSK mTLS Config

[mtls]
enabled: true
cert_file: "cert.pem"
key_file: "key.pem"
ca_file: "ca.pem"
require_client_auth: true

🛡️ Open Policy Agent (OPA) Integration

OPA Policy Enforcement

use opa::{Opa, Policy};
fn main() {
    let policy = Policy::from_file("policies/authz.rego").unwrap();
    let opa = Opa::new().add_policy(policy);
    let input = serde_json::json!({"user": "alice", "action": "read", "resource": "document"});
    let allowed = opa.evaluate("data.authz.allow", &input).unwrap();
    println!("OPA allow: {}", allowed);
}

TSK OPA Config

[opa]
enabled: true
policy_files: ["policies/authz.rego"]
endpoint: "http://localhost:8181/v1/data/authz/allow"

🔑 Secrets Management

HashiCorp Vault Integration

use vault::client::VaultClient;
#[tokio::main]
async fn main() {
    let client = VaultClient::new("http://localhost:8200", "my-token");
    let secret = client.read_secret("secret/data/api-key").await.unwrap();
    println!("API Key: {}", secret["data"]["data"]["api_key"]);
}

TSK Secrets Config

[secrets]
provider: "vault"
address: "http://localhost:8200"
token: @env("VAULT_TOKEN")
paths: ["secret/data/api-key", "secret/data/db-password"]

🔐 Advanced Authorization

Attribute-Based Access Control (ABAC)

use tusklang_rust::{parse, Parser, security::ABAC};
use serde_json::json;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut parser = Parser::new();
    let abac = ABAC::new();
    parser.set_abac(abac);
    let tsk_content = r#"
[abac]
policies {
    admin_access {
        condition: @request.role == "admin"
        action: "allow"
        resource: "*"
    }
    time_restricted {
        condition: @request.time >= "09:00" && @request.time <= "17:00"
        action: "allow"
        resource: "office"
    }
}
[access]
can_access: @abac.evaluate(@request.user, @request.resource, @request.action)
"#;
    let data = parser.parse(tsk_content).await?;
    println!("ABAC result: {}", data["access"]["can_access"]);
    Ok(())
}

🛡️ Security Hardening

- Enforce least privilege for all services - Rotate secrets and certificates regularly - Enable audit logging for all sensitive actions - Use network segmentation and firewalls - Monitor for suspicious activity and anomalies

🧪 Testing Advanced Security

#[tokio::test]
async fn test_mtls_server() {
    // Use reqwest with client certs to test mTLS endpoint
    let client = reqwest::Client::builder()
        .add_root_certificate(reqwest::Certificate::from_pem(include_bytes!("ca.pem")).unwrap())
        .identity(reqwest::Identity::from_pem(include_bytes!("client.pem")).unwrap())
        .build()
        .unwrap();
    let resp = client.get("https://localhost:8443/").send().await.unwrap();
    assert!(resp.status().is_success());
}

🎯 What You've Learned

1. mTLS - Mutual TLS for secure communication 2. OPA - Policy-based authorization 3. Secrets management - Vault, environment, and rotation 4. ABAC - Attribute-based access control 5. Security hardening - Best practices for robust security

🚀 Next Steps
