1. Ensure secure input validations
Every app requires users to input their credentials and specific information to access data or services. If the input validation process is prone to malicious injections, it can cause data theft or cyberattacks.
The best way to ensure secure input validations is to reduce dynamic queries with string concatenation. In other words, dynamically built transact-SQL statements or batches that you can reuse should not have concated strings. To identify such strings, you can apply a rule-based system.
Further, you can change the harmful HTML inputs and have plain text input from users by replacing innerHTML with innerText.
2. Keep libraries and frameworks up-to-date
Without proper updates, libraries and frameworks that are the basis of your apps can cause security issues.
3. Encrypt sensitive data at rest and in transition
You can get an SSL certificate from several certificate authorities (CA) that ensure higher trustworthiness among users. The process of SSL certificate involves the generation of a Certificate Signing request (CSR) along with all the details of the requestor.
4. Use a Content Security Policy (CSP)
It is a set of rules that you can define in the HTTP header of the web page. It allows you to define the sources from which the browser can load the content. It is a way to mitigate the risk of cross-site scripting (XSS) attacks.
5. Add an extra layer of security
If you are keeping the data on physical hardware or on premise infrastructure, ensure protection through another layer of security. For example, you can ensure that data access from on premise data center is secure through two-factor authentication (2FA).
It is a process of authenticating users for data access through their email ID, password, and a passcode sent on their device. However, there can be different forms of a passcode, and it can be a one-time password, a link to log in, or an encoded message.
