Back end Web Development: 5 Best Measures for a Secure Website

No matter how advanced features you use in back end web development, there are high chances that your website can be attacked by malware, hackers, or users. Such attacks enable fraudulent people to gain access to confidential data, like bank details and health-related information. Cyberattacks not only harm users, but they also spoil the reputation of developers.

So, if you are a developer, you must know reliable ways to strengthen your back end security.

Having taken this fact into account, we have written this blog to familiarize you with the 5 best ways to make your back end strong enough to keep cyberattacks at bay.

Top 5 Methods for Secure Back end Development:

As a developer, if you adopt the following practices in back end web development, you will considerably reduce the chances of unauthorized access to your website:

1.     Multi-Factor Authentication:

Multi-factor authentication (MFA) means adding extra steps for the authentication of a user during login. Let’s get a clear idea of MFA with the example provided below:

Google or Facebook may send a code to the user’s phone number when they sign in with their email, or they may need a biometric scan.

Thus, an additional layer of protection is added, which is better than the usual password and email methods.

2.     Data Encryption:

Personal data, credit card details, and passwords must be kept confidential, as they are sensitive information. In fact, such details must not be stored in the database in their plaintext format. Doing so is as foolish as leaving your door open with the line, ‘come in and steal whatever you want.’

Keep in mind that if data is hacked, all sensitive data will be leaked. To cope with this issue, rely on encryption.

Encryption is like keeping your door locked with a strong key. It scrambles the data so well that it becomes beyond understanding. Even if somebody breaks in, they will not be able to understand what it says. Thus, you can keep your sensitive information safe.

The following are some encryption methods used in back end web development for indubitable security:

1.     Hashing: It converts data into a fixed-length string.

2.     Asymmetrical encryption: With a pair of keys (private and public), asymmetric encryption enables encryption and decryption.

3.     Symmetrical encryption: It utilizes a single key for encryption as well as decryption.

These encryption techniques can allow you to miraculously improve the security of your back end web applications and protect confidential data from fraudulent access and leaking.

3.     Disaster Recovery and Data Backup:

A wise back end development strategy is incomplete without regular data backup and disaster recovery. If a physical loss of data happens, for example, a hard disk failure, or software data loss, like a storage error or damage because of malware, data recovery is possible with backup.

Ensure that you choose backup software and fix a backup schedule, like daily, weekly, or monthly. Your backup methods must have full backups, incremental backups, and differential backups.

4.     Proper Validation and Sanitization:

It’s foolish to trust the input provided by the user. In other words, you’d better assume that any data given by users may be malicious without proper validation and sanitization.

Validation means checking whether the input provided by the user harmonizes with the expected format, type, and constraints. 

If there is a form field for an email address, validation will ensure that the input sticks to the correct email format, and it’s not just normal text.

Sanitization means the removal and modification of harmful elements or characters from the user input for the prevention of security vulnerabilities. For instance, if you eliminate HTML tags from user-generated input, it can stop cross-site scripting attacks.

That’s why validation and sanitization are a must-have in back end web development.

5.     Authorization and RBAC:

Authorization means determining whether a user is permitted to do a particular thing on a specific resource. However, it’s wise not to allow some users to get some permissions. It’s because limiting permissions leads to reduced risk. The fewer the permissions are, the smaller the attack surface is. Thus, the fraudulent people can’t take advantage of vulnerabilities. That is where Role-Based Access Control (RBAC) is required. RBAC is a mechanism to control and manage access to resources according to the user’s role in organizations. That’s why businesses look for it when they hire Angular development services. 

In a usual website, there is an administrator with full access to all resources, and a user who can view their own data.

RBAC makes sure that each user can only do those things that are allowed to them according to their given role. Let’s get it clear with an example below:

A user is not allowed to modify the data of another user or have access to administration functions. When such permissions are limited according to the requirements, the risks of data breaches and unauthorized access are reduced to a large extent.

Conclusion

The 5 best ways for safe back end web development are multi-factor authentication, data encryption, disaster recovery and data backup, validation and sanitization, and authorization and RBAC.

By using these measures, you can reduce the chances of a cyberattack on your website.
