Web development involves creating websites and digital applications that allow people to access information and communicate with others online. It encompasses front-end, back-end, and database technology.
A website’s back-end is responsible for connecting the site to a server and processing data. It’s also where a web developer can write code that ensures a site runs properly and securely.
The front end is the part of a website that you see and interact with. This includes the graphical user interface, navigation, and user-entered data.
Moreover, they ensure that websites are responsive and work on any device – desktops, tablets, and smartphones. This is crucial for a successful application because systems vary in screen size and operating system (OS).
A back-end developer is a professional who works on the server side of a website. These developers create a site’s structure, data, and logic with computer programming languages.
A Back End web developer uses a variety of programming languages to create the back-end of a website or application. They write codes that enable web browsers to communicate with servers and databases.
A back-end web development career requires strong communication skills and a holistic understanding of the tech industry. This includes keeping up with technological updates to the latest web languages and platforms.
Databases are the back-end of web applications, storing user information, session data, and other application data. They provide a central repository for all of this information, so that it can be accessed and manipulated easily.
A web application database can be any type of database, including flat files, relational databases, object-relational databases, and NoSQL databases. Each has its own advantages and disadvantages when it comes to storing and retrieving data.
Almost all modern websites and web applications store some form of content in a database. These include images, articles, different types of information, and page layouts.
A database also allows users to quickly update their content if they need to make changes. This is especially important for dynamic web applications that need to be updated frequently.
Web applications have vulnerabilities that can be exploited by malicious hackers. These flaws can cause significant damage to a company’s data and operations.
OWASP Top 10 threats include SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). Security experts recommend avoiding these flaws and addressing their root causes through proper security testing throughout the SDLC.
Secure application development requires that coding practices incorporate confidentiality, integrity and availability. It also includes security controls to prevent unauthorized activities and enforce separation of duties.
The right security solution is key to a secure Web application. These solutions provide deep visibility and control over traffic, including application layer inspection to identify suspicious behavior or actions that may violate corporate policy.
Security solutions can help organizations protect their customers from phishing attacks, malware, and unauthorized access to sensitive information. They also allow companies to monitor and mitigate data loss in real time, reducing costs associated with exfiltration. They can also inspect network traffic to identify known-bad and malicious sites.
