A “Web Application” is an application created using web technology that runs through a browser (web browser) without having to be installed on the user's computer in a way. Technically, web applications often use client-oriented web programming languages. (client-side) such as HTML, CSS, and JavaScript for displaying and interacting with client users And there is communication with the server that provides the data. Using server-oriented web technology (server-side) such as Node.js, Django, Ruby on Rails, PHP, or ASP.NET
Web applications can have interactive features. (interactive) or static (static) The behavior depends on the purpose and needs of the application.
Web apps are becoming more and more popular. Because it can be accessed from anywhere in the world with an internet connection. It also allows users to access their data from any device. with web browser including smartphones and tablets
Additionally, web apps can be updated and changed without redeploying the entire application. รับทำเว็บไซต์ ขอนแก่นThis makes it more flexible than a typical desktop application.
An example of a well-known web application is an online trading website. (e-commerce), social media websites (social media), online games, accommodation or seat reservation systems, business management systems (Enterprise Resource Planning - ERP), and others according to the needs of users and businesses that use them. work
Why a web app?
-Convenience: Access from anywhere, anytime, as long as there is internet access.
-No installation required: No need to waste storage space on your device.
-Easy to use: The interface is designed to be easy to use.
-Always updated: Developers can update new features. at any time without the user having to do anything.
-Supports all devices: whether it's a computer Mobile phones or tablets can be used.
Examples of web applications that we use in our daily lives
-Social media: Facebook, Instagram, Twitter
-Email: Gmail, Hotmail
-Google Drive: for storing files online
-Google Docs: for working on documents online
-Applications for online shopping: Lazada, Shopee
How do web applications work?
When we type the URL of the web application into the web browser. Our computer sends a request to the server where the web application is stored. The server processes the request and returns the information to our web browser to display the web page we see.
Web applications are the use of the power of the internet to create programs that can be used anywhere, anytime, making our lives easier and more convenient.
Are web applications secure?
Web App Security or web application security This is an important aspect that cannot be overlooked, as web apps often store sensitive information that is often targeted by hackers. Protecting personal and financial information from identity theft online fraud Spreading false information Until the destruction of data is absolutely necessary for business. Web application providers should have proactive security testing to find vulnerabilities. Security operations are ongoing. and having a remediation plan in case of application security emergencies as well. So that our web apps are not at risk from security threats. Cybersecurity and provide peace of mind to web application users.
9 guidelines for web application security
1. Set up security
Your Web App's security settings should be checked and updated regularly to prevent erroneous security settings. You'll also need to use the OWASP Secure Coding Checklist, a tool that helps you check the security of your code. Including checking data received and exported from the system. Including identity verification and password management
2. Authenticate and manage sessions
It is the main mechanism that helps prevent unauthorized access and maintains the security of user data. Session management also helps us ensure that user data is kept safe during their interaction with the application. It also helps provide a smooth user experience by remembering user status information. This is essential for providing continuous and efficient service.
3. Prevent CSRF
CSRF protection using CSRF Tokens or SameSite Cookies improves web app security by preventing bad actors from requesting information or making transactions from websites without permission from real users. It also gives developers better control over user access to data. And reduce the risk of important information being stolen or altered without permission.
4. Prevent Insecure Direct Object Reference
Insecure Direct Object Reference (IDOR) protection helps secure web apps by preventing attackers from unauthorized access or modification of data through the manipulation of object identifiers. Using strong authentication and complex identifiers is another way to prevent this vulnerability. Additionally, not exposing identifiers in URLs or in the POST body is a good way to mitigate this. There is also the risk of being attacked using the IDOR method.
5. Important information must be encrypted.
Data encryption protects web apps from unauthorized access and cyber threats. By transforming readable information into an unintelligible form. This keeps the data safe from being intercepted or misused. Additionally, encryption helps maintain the confidentiality and integrity of the data. It also helps keep our web applications compliant with security regulations on the internet.
6. Use HTTPS and HSTS
Using HTTPS encrypts data sent over the internet. It prevents data from being intercepted or altered by third parties, while HSTS allows websites to always enforce encrypted connections. This reduces the risk of malicious attacks. Man-in-the-Middle It also helps websites load faster by eliminating the need for redirects from HTTP to HTTPS.
For web app design and development, security is an issue that should be taken into consideration from the very beginning. Especially when online transactions update their software regularly.
Many people may think that it has little to do with Web Apps, but actually checking and updating our own software such as frameworks, libraries, and operating systems. It is an important part of security. Because it will help block vulnerabilities that may be taken advantage of by hackers. Including fixing various errors in the system and improving modern security. It also allows the operating system and libraries in use to integrate smoothly and efficiently with other software.
7. Install WAF
Installing a WAF (Web Application Firewall) improves web app security by protecting against attacks that involve vulnerabilities such as SQL Injection and Cross-Site Scripting (XSS). WAF acts as a shield. By checking and filtering information that comes into the system. To prevent malicious data from reaching web applications, this WAF can be customized to meet the specific needs of each business. Helps manage security more systematically and easily.
8. Check safety regularly
Regularly review web app security With penetration testing and code verification to prevent vulnerabilities It helps ensure that sensitive data and website functionality are safe from cyber threats at all times. It also helps users to be confident in the trustworthiness of the website. This has a positive effect on the reputation and trust of customers in the business as well.
9. Prepare an emergency response plan in advance.
Having a contingency plan allows us to respond quickly and effectively to unexpected events. This includes protecting data from loss or unauthorized access. It also reduces system down time and maintains user trust. Good planning also allows for faster system recovery after an attack. and it is considered good risk management This will allow the web app and business to continue operating without any problems.
Having strict measures in place and regular updates Including following all 9 recommendations that have been gathered and shared as knowledge for this article. This will help prevent our web apps from becoming targets of cyberattacks. Although no security system in the world can completely prevent such attacks, But following news, new knowledge and updating the system to be up to date all the time. รับทำเว็บแอปThis will ensure that our web apps are in the most stable and secure state possible.
