A banner is a message or announcement that appears on a website. It can display useful information about the website, its features, advertisements or other relevant details. In cybersecurity, it often refers to the information provided by a network service when it connects, which can include the server software’s name, version, and other details. In some cases, banners can also be used by cybercriminals to gain useful information about a system’s potential vulnerabilities.
Banner Examples
1. Sale Event Banner
Imagine you’re browsing your favorite online clothing store. As soon as you arrive on their home page, you’re greeted with a large, bright banner across the top of the screen. This banner announces an ongoing sale, with discounts up to 50% off on selected items.

This is a classic example of how websites utilize banners. They effectively capture visitor attention and provide vital information at a glance. In this case, the key details pertain to a sale event. Banners such as this not only improve user interface but can also enhance customer experience by keeping them informed about such special events and promotions.
2. FTP Server Banner
Let’s say you’re connecting to a FTP server to transfer some files. When the connection is set up initially, a message pops up showcasing the name of the server and the version of the software it’s currently running. This message or announcement is technically known as a banner.
The banner in this scenario helps users identify the server software and its version. This is particularly useful for system administrators who might need such information for routine checks or troubleshooting. However, server banners can also expose potentially sensitive details to malicious users who might be looking for system vulnerabilities to exploit.
3. Privacy Policy Banner
Suppose you’ve decided to explore a new online application. After creating your account and logging in for the first time, you’re presented with a banner. This banner clearly states the application’s privacy policy and terms of agreement.
This example serves to show how banners participate in legal and ethical web practices. The information displayed in the banner helps to inform users about important policies and agreements. This boosts transparency, ensuring users are aware of how their data is handled and promoting trust in the application’s services.
Conclusion
In essence, a banner is a versatile tool in the digital world. Whether it’s promoting an online sale, identifying server software, or making users aware of privacy policies, banners play a crucial role in providing key information and enhancing user experience.
