Top 10 Node.js Security Best Practices

 

Node.js is a Javascript runtime built on Chrome’s V8 Javascript engine. It is widely used for building scalable and lightweight network-driven applications. It can be scaled up easily horizontally as well as vertically. Apps development with Node.js are used for both client-side and server-side apps. It has an open-source Javascript runtime environment/ model which provides caching of single modules. Similar to the other programming languages or frameworks, node.js is susceptible to each type of web app exposure. Though the Node.js is secure, third-party packages may require more security standards to protect your app. According to the study, 14% of NPM ecosystem is impacted and 54% of the NPM ecosystem is about to be impacted indirectly. Here we’ll see the top 10 best practices for node.js security. But before going to the security best practices, let see, why do node.js projects have security issues?

Why Do Node.js Projects Have Security Issues?

Open-source apps derive licensing and security risks from their open-source elements. Also, the security detecting tools like static and dynamic code assessment cannot detect open-source exposures efficiently. 

To detect open-source elements in Node.js, you need to assess the NPM index files which explain the dependencies. All things considered, these index files don’t incorporate reused open-source elements. Some of the time, open-source community open-source projects to lower time-to-market, speed-up development and add functionality. As a result, developers can launch code snippets, functions and techniques into files. Also lots of node.js web development projects include licensing terms other than real Node.js license.

Top 10 Node.js Security Risks And Solution Practices-

Node.js security issues can show you vulnerabilities like code injection and advanced constant threats. Let us see a list of Node.js security risks that may cause these vulnerabilities and its possible solution practices.

1. Validate User Input To Limit SQL Injections And XSS Attacks-

Cross-site scripting or XSS lets hackers to infect vulnerable client-side scripts into website pages viewed by various users. Vulnerable client-side scripts can cause data breaches. Also the hacker can use Javascript code. Reason for this is not validating input from users. So, whatever users type in the search field, if doesn’t discovered in the database, it will be sent back to them in the same old form. So, if a hacker puts JS code instead of the product name in the search bar, he can execute a similar JS code.

Solution-

One can validate user input. To prevent XSS attacks in Node.js, one can use output encoding methods or tools like Jade engine with in-built encoding frameworks. You can also opt for, XSS-filters or Validatorjs for this.

2. Implement Strong Authentication-

Having weak, broken or incomplete authentication mechanism is a next most common vulnerability. Mostly it is because, may developers think about authentication as “we have it, so we’re secure”. In fact, weak or inconsistent authentication is easy to bypass. 

Solution-

One solution is to use authentication solutions like OAuth or Okta. If you prefer to stick with Native Node.js authentication solutions, you have to know some things. When you create passwords, don’t use Node.js built-in crypto library, use Bcrypt or Scrypt. Ensure to limit failed login attempts, and don’t tell the user if it’s username or password that is incorrect. Rather, return a generic “incorrect credentials” error. Also, you need proper session management policies. Instead, return a generic “incorrect credentials” error. Also, you require proper session management policies. And be sure to implement 2FA authentication. If it all done in a proper manner, it can increase security of app to the next level. You can so it with modules like node-2fa or speakeasy.

3. Avoid Data Leaks-

It is easy to send all data for a particular object to the frontend and just filter what to show there. Also, attackers can easily get hidden data sent from the backend. For instance, imagine that you want to show a list of users who signed up for an event. You execute a SQL query to get all users for that particular event and send those data to the frontend, and there you filter it to just show the first and last name. But all the data you don’t want to show is easy to access through the browser developer console. This causes data seaks.

Solution-

Only send the data that is required. If you just need first and last names, retrieve just those from the database. It creates more work, but it’s worth it.

4. Regularly Scan Apps Automatically for Vulnerability-

Node.js ecosystem contains some libraries and modules to install. Generally, most of them can be used in your projects. It produces a security risk. You cannot be completely sure that it’s secure while using code written by someone else. 

Solution-

To resolve this, you must run regular automated vulnerability scanning. It helps to find dependencies with common vulnerabilities. Also, you can opt for NPM analysis for basic monitoring, yet consider using tools like Retire.js, WhiteSource Renovate, OWASP Dependency-Check, OSS INDEX, Acutinex, and NODEJSSCAN. 

5. Establish Logging And Monitoring-

Monitoring and logging are associated with Node.js security. As your main goal is to make mechanisms secure from start, but in fact it needs a continuous procedure. And for this, you need monitoring and logging.  

Solution-

Some of the hackers want to stay unidentified for a longer time, whereas some of them want to make your app unavailable that can be found out without logging. In such cases, log and metrics monitoring will help to detect the wrong matter. With a basic logging, you can’t get enough data for understanding if you get strange-looking requests from your app, a hacker or a third-party API. Some of the tools offer the precise layers to improve the protection of your system, depending on data. Data is vital to assess and identify probable exposures and invasions of your app. One can make various routines that implement depending on a few pre-decided system behaviors. Monitoring and logging explain everything that occurs inside an app. So the monitoring functions as an indicator of it will come to you if anything vulnerable is recognized.

Secret Tips To Secure Your Data While Everyone Works From Home

Remote work has many benefits for employers and employees. Analysis has reported greater levels of job satisfaction, less stress and higher productivity. Many employers have given feedback indicating improved retention, while also being able to reduce office expenses. Numerous employers have given feedback showing improved retention, while also  being able to reduce office expenses. Despite these advantages, remote work also presents some challenges. On of them is- How to keep work related information secure when someone is accessing it at home? A survey found that entrepreneurs feel the risk for data breaches with remote work. However, proactively addressing security challenges by following the below steps will enable your team to work remotely without risking compromising your data.

Tips To Keep Your Data Secure While Everyone Works From Home–

1. Ramp up user-training efforts-

While criminal attacks are responsible for most of data breaks, human error is also a significant contributor to digital-security issues. An analysis found that 36 percent of all such cases were directly attributable to human error. Phishing messages are one of the most widely recognized threats facing employees, tricking them into clicking on fraudulent links that are intended to install malware or steal account information.

These hacking tricks can be very complex, even going so far as to imitate official communications from your organization or its partners. Since employees are working outside the workplace, you should ensure that they understand the dangers of phishing and other attacks. Instructing them to recognize fraudulent communications will keep numerous serious breaches from ever turning into an issue.

2. Require two-factor authentication-

Regardless of whether a work-issued PC is stolen or your employee uses the same password for work as they do for another account that has been compromised, there are endless roads that attackers can use to access employee information — even when your team is using  advanced digital-security best practices. To avoid all this, many companies are requiring two-factor authentication when employees sign in to their accounts. Recently, “Two-factor authentication adds a layer of redundancy to ensure that only the actual account owner can access their account. The attacker can steal the employee’s password, but won’t have the phone that receives the verification code.

They definitely wouldn’t have a fingerprint which is used in some systems. Including one extra step to login process could make all the difference to keep hackers out. Two-factor authentication systems can also serve as a kind of alert when an unauthorized user is attempting to log in to an account. This will enable remote workers to know when they have to change their secret word or get in touch with you about a potential issue. This will help remote employees to know when they should change their password or contact you about a potential issue.

7 Important Considerations When Building A Mobile App

Whether you accept it or ignore it, but the fact is you can’t ignore the growing presence of mobile apps. With everybody from children to adults, getting snared to Apps. Nowadays many enterprises have begun investing in creating business apps, not just for their customers but also for their employees. When the challenge is so high, user expectations for the app quality also goes high. To ensure zero drawbacks, it is prudent to invest in App testing at every stage of development. Not at all like testing traditional desktop apps, mobile App testing is truly complicated and challenging. Let us see the 7 important considerations when building a mobile app.

Top 7 important considerations when building a Mobile App

Mobile App Development

1. Know your audience-

Your company needs to analyze the competition to determine the type of applications they are building, why they create that app and how they are engaging in the process. Listing out the competitor companies and search for their apps on the app store and google play helps you to analyze the level of development of your competitors. This helps you to set the development goal for your application. Pilot the applications yourself. For this read the reviews on the store pages to realize which features are liked by clients and what part of experience need to improve. With the help of this information you can improve your application to stand out among competition and also to serve your target audience in a more efficient and exciting way.

2. Attractive User Interface-

User interface is a vital part of an application. UI is the first impression of app it presents to the users. The common objective of UI is to fulfill the audience needs. It is always good to keep the UI, simple and easy to use. Probably the most ideal approaches to comprehend client reaction is to go for UI group testing. This helps you to understand the initial response and feedback from real users in real world conditions. It also gives you the flexibility to test your app with users from different locations. 

3. Compatibility Challenge-

The same app may have different results on devices having different screen sizes on different platforms and browsers. It is beneficial to test the app with real users, in real time, on real devices using real platforms to understand what works best and what does not work. The goal is to ensure that the app works well with different devices, operating systems as per the exact expectations. In the case of devices, developers need to factor in the impact on battery life, the RAM used, and the CPU processing power of different devices.

To cover these aspects using traditional testing is difficult and also expensive. Testing on real devices can never be replicated by emulators. The least complex and most savvy answer for battle the issue of similarity is to put resources into publicly supported App testing. Getting real insights in transit your App works will empower you to improve your app performance across devices, browsers and platforms.

4. Provision for updates for Mobile Apps-

Users will expect new features and upgrades in your app.If you want your app to stand out in the market, you need to invest in upgrading your App and also in additional testing for each upgrade. Also you need to ensure that the released updates are working well in different OS versions. It is also necessary to ensure that the app is easy to upgrade or install. Your testing procedure should cover installation, updates and un-installation of the App to reveal any mistakes all the while.

5. Internet bandwidth and other external Factors-

You need to understand the impact of internet bandwidth on your App’s quality. According to the results of, how good or bad the internet connection is, application behavior will be different for different users. You could lose your sales by 1% for every 100 milliseconds of load time. Most of the users won’t wait more than 3 seconds for a page load. Additionally, a mobile app in real world conditions is inclined to intrusions like lack of coverage and incoming calls. It is difficult to reproduce the fluctuating conditions because of the  network and location in a lab. The simpler way to estimate and fix these issues is through crowd-sourced performance and interrupt with testing that will allow you to understand the effect of interruptions like incoming calls and network fluctuations.

6. How to Monetize the App-

Every business is ultimately creating their apps to monetize them.  Companies must consider the budget and maintenance costs of their application, as well as which methods will help them make money off of their users. Possible options include:

Advertising: 

Most of today’s apps use banners, video, native, interstitial, and text ads to make a profit. This doesn’t force users to purchase the app, it does create distractions or pauses in the experience.

Freemiums:

Apps can be free to download, but users will have to upgrade to get full access. This pay-to-use method allows some users to enjoy a limited version of your software with free of cost, while others will enjoy the experience and pay to continue. While you won’t make money off of everyone, your users will not be turned off by having to purchase ahead of time or seeing obtrusive advertisements.

In-App Purchases-

Game developers do a great job of monetizing in-app purchases through play credits, character unlocks, and level unlocks. Again, not everyone will engage, but it is an effective and psychologically-based way to tantalize the user to enjoy more of your product. 

App Installs–

This is one of the riskiest options, because not everyone will be enticed to spend money on your app before they try it. If you have high user reviews from those who have already used it, more users may be encouraged to spend money. It is beneficial to create a related audience, but you will secure revenue from everyone who uses your product.

7. Security challenges-

A security testing can help uncover vulnerabilities of data leakage during the transmission and working of the App. Your App must meet the authorization policies and other security standards set, to ensure that the user data is protected. You also need to include certificate testing in your strategy to meet the mandatory certificates set for compliance for devices and apps.
