应用级安全管控如何创建

# 示例代码（Python + SQLAlchemy）
from sqlalchemy import text

query = text("SELECT * FROM users WHERE username = :username")
result = session.execute(query, {"username": username}).fetchall()

// 示例代码（Node.js + Passport.js）
const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;

passport.use(new LocalStrategy(
  function(username, password, done) {
    User.findOne({ username: username }, function (err, user) {
      if (err) { return done(err); }
      if (!user) { return done(null, false); }
      if (!user.validPassword(password)) { return done(null, false); }
      return done(null, user);
    });
  }
));

# 示例配置（Logstash）
input {
  file {
    path => "/var/log/app/*.log"
    start_position => "beginning"
  }
}

output {
  elasticsearch {
    hosts => ["localhost:9200"]
    index => "app-logs-%{+YYYY.MM.dd}"
  }
}
