How to Address Key Vulnerabilities in the MEAN Stack

MEAN Stack Online Training | MEAN Stack Training in Noida | MEAN Stack Training in Delhi

Using the MEAN stack (MongoDB, ExpressJS, AngularJS, and NodeJS) has become a popular choice for web developers. One explanation for this phenomenon is many middleware plugins and dependencies that make it so easy to deploy. MEAN Stack Online Training will teach you everything you need to know about designing a wide range of applications through real-world examples, industry projects, and hands-on training.

Why now?

As a result of working with a full MEAN stack, the developer’s job is to make sure that the application’s cyber security is appropriately safeguarded. That’s why developers must be aware of the dangers and security implications of every technology component they use.

The MEAN stack, for example, is simplified for speed, and all of its levels are written in JavaScript. As a result, JavaScript can be used for both the client and server. However, because they are also responsible for security, they must verify the safety of every layer of the application. Various institutions are there which offer MEAN Stack Training in Delhi. 

Let’s start with MongoDB’s flaws.

Like HBase and Cassandra, MongoDB is a document-oriented NoSQL database that is JavaScript-enabled. MongoDB is mainly compatible with MySQL, although vulnerable to SQL injection attacks.

Even though MongoDB isn’t subject to SQL language abuses, its JSON documents can be tampered with maliciously. In addition, the Common Vulnerabilities and Exposures (CVE) database shows that MongoDB has its own set of security issues.

Next, let’s make ExpressJS safe.

NodeJS’ web and mobile framework are ExpressJS. NodeJS speeds development and provides framework components.

The most popular NodeJS framework is vulnerable to injections and cross-site attacks. All of NodeJS’ vulnerabilities can be exploited. Developers must-watch ExpressJS updates for vulnerabilities.

The app can also use the Express framework to add middleware plugins to all routes at once. When laying up middleware, keep a few things in mind.

Preventing cross-site scripting attacks on AngularJS

To allow for modular client-side development with the least amount of code possible, Google created and maintained AngularJS, a front-end MVC framework. Cross-site scripting (XSS) attacks can be carried out against this framework.

MEAN stack developers must keep track of the complete list of vulnerabilities in AngularJS at Mustache Security’s Google Code project site to fix this issue (and address them accordingly).

Identifying constraints with NodeJS

NodeJS is necessary for constructing online apps with networking and server-side features. Google’s V8 Javascript engine enables real-time server-client communication.

You don’t need a separate web server with this utility. Despite its importance, it inherits all JavaScript vulnerabilities (including some new attack vectors on the server-side).

DevOps demands full-stack secure development. This technique requires additional controls to maintain security throughout development.
