With the emergence of various technologies, there’s also a spike in cyberattacks and the rise of advanced hacking mechanisms. Data breaches in the fourth quarter of 2023 exposed more than 1.5 million records in the United Kingdom (UK). Such vulnerabilities have urged various companies to look for web application security best practices.
Shutting one’s eyes to web security can lead to grave consequences and threats at large. For example, even a bleak error in the application code, or lack of standard practices in development projects provides potential for hackers to compromise your business security.
This blog enlists the web application security best practices and explains how it can help you stay proactive against several threats.
What is web application security?
Web application security refers to steps, methods, and practices involved in making web applications secure against cyber attacks. It typically encourages developers to adopt industry-standard practices in writing application code or upgrading legacy systems against various potential threats.
For example, Python for web development helps to create secured applications packed with powerful performance. Security is vital in web or mobile apps due to ever increasing potential threats.
Dedicated focus on web application development helps to build a secure code that offers protections against XSS (cross-site scripting), malware, spyware, etc.
Here are 10 web application security best practices
1. Strong password policy
Enforcing password policies for all applications acts as a first line of defence against various cyber attacks. The password policies compel rules for users to create and use strong passwords for accessing the web application. This makes it challenging for cybercriminals to gain access to user accounts.
2. Encrypt business-sensitive data
Encryption refers to the act of encoding data so that it is not visible to unauthorised users. If your web application involves data storage capabilities and deals with sensitive data, you must use data encryption methods or tools. It is an effective strategy for building the best web application security solutions.
3. Deploy role-based permissions
If you have various employees managing your web application, it is high time you leverage role-based permission techniques. This means that different employees with access to web application admin can access only restricted areas that are meant for their use. This helps to ensure high-level security measures and access to only authorised users.
4. Use a security provider mechanism
There are various handy protocols like OAuth, SAML, SSO, and others that offer stronger protection against cybercriminals. For example, let us analyse how OAuth works.
OAuth, or open authorization, permits users to grant third-party access to their accounts without sharing their passwords. It sends an authorization token from one application to another, which contains information about the user’s privileges. Once the token expires, the user loses control of the application.
So, users can transfer access without having to share passwords.
5. Regular auditing
Web app development does not end with the application’s launch. Maintenance activities like regular auditing keep the application relevant to users.
Web application audits successfully identify key weaknesses or issues in the application’s code and configuration. So you can easily determine which areas need immediate improvements and reduce the risk of cyber attacks.
6. Use a secure wifi connection
Choose a secure Wi-Fi connection that prioritises security. An insecure connection places your web application at various risks and should be avoided.
7. Keep your application up-to-date
Your web application is built on frontend and backend technologies. Most technologies receive regular updates every six months, year, or after a few years. It is advisable to ensure you update your web application to the latest technologies for deploying automated performance and security enhancements.
Similarly, several frontend updates may be required based on the latest user demands. For example, a Reactjs developer can update or enhance your application’s user interfaces to launch a refreshing outlook.
8. Install HTTPS
HTTPS is based on the top of HTTP (Hypertext Transfer Protocol) and uses the Transport Layer Security (TLS) protocol, which was earlier called Secure Sockets Layer (SSL).
HTTPS is among the most widely adopted web application security practices, and it aligns with SEO strategies. Running applications on HTTPS uses encryption and verification to secure communications between your browser and the server.
9. Use QA test plans
Web application security testing can help you determine whether the application is running properly. In simple words, they help find vulnerabilities, such as bugs or issues, and eliminate them from the web application code.
10. Take Backups
Taking regular backups over the Cloud or an external storage system helps you manage urgent situations, such as an attack. It also provides a single point of return when your application suffers from outages.
Conclusion
The above ten points are some of the best web application security practices. You can deploy them into your web application development and maintenance projects to efficiently stay proactive against various vulnerabilities and threats.
