What is Captive Portal Login?

Till now, we know the very basic idea behind the captive portal, that is providing free access to Wi-fi to the customers. So to be able to get access to this free Wi-fi, businesses have their respective web portals via only which the access can be provided. This is called the Captive Portal. The first web page in this Captive Portal is the Captive Portal Login page.

Now this page can contain quite a few things. Either this could be a login page where an ID and password, which will be provided by the business authority, will be required. Or there could be several advertisements of the same business, also including their currently running discounts, schemes, packages etc. Also, there could be chances of advertisements from the sponsors of the business being present to be able to achieve strategic marketing goals.

Hence, we can say that the Captive Portal Login page is something which any customer/user will have to go through at least once in order to have access to the free Wi-fi. This page could be anything from a regular login page to a targeted advertisement for self or sponsors.

What is

The main idea behind is to allow android devices to be able to access the public Wi-fi that the businesses give to their customers. Since your device is being connected to a public network, it may be vulnerable to malware attacks by hackers. To protect your device from such activities, the captiveportallogin package creates a firewall or a barrier for your device. This protects your device thoroughly from malicious attackers who tend to take advantage of such open public networks.

Open Wi-fi networks also tend to have another disadvantage, apart from being vulnerable to attacks, and that is their internet speed. Since a very large number of users tend to use the same Wi-fi network, the speed naturally decreases. Here, as well, comes to the rescue! This package not only stops this bandwidth hogging by limiting the speed for downloads that take place, it also restricts the total number of downloads happening via that particular Wi-fi. In some cases, this package also holds the capacity to block the websites that download files to your devices. Doing this, helps in improving the overall bandwidth availability as well as forbids just one person from consuming the entire speed bandwidth for themselves.

Types of Users of Captive Portal Login

Since there is a huge chunk of population using public Wi-fi at the same time, it is evident that there will be different types of users accessing the network, especially at the airports, restaurants and hotels. After careful evaluation, the types of users using a public network facility can be divided into three categories:

  1. Authenticated Users: These are the genuine users who accept the terms and conditions of the captive portal login page, and access the internet via a login and password or by viewing the adverts. Once the captive portal login has confirmed that the user is authorized, the traffic may proceed across the switches without interruption.
  1. Unauthenticated Users: These are those users who have somehow surpassed the login page and have not gone through the required steps to access the internet. If the client is discovered as unauthorized, the portal will divert his/her/their HTTP to the switch and request authentication, ensuring that all traffic generated by the user is routed through the switch.
  1. Unknown Users: These are the potential hackers and malware attackers who break into the system. When dealing with unknown users, the web page is unable to identify the client. The captive portal will prevent HTTP traffic from reaching the switch. The portal will then query the switch to determine whether or not the client is authorized.

How to Protect Yourself While Using Captive Portal?

Since quite a few people tend to use public networks, it is not promised that everyone may use it with the right intention. There is always an open threat to security and data theft. Hence, it is recommended to minimize the use of public networks and avoid them as much as possible. However, having said that, it might not always be feasible to not use a public network, so whenever you choose to do so, you should follow some ways in which you can protect your data as well as your device. We will have a look at them in this section.

  1. Ensure that your devices are well-patched and updated. Operating systems tend to update their newly discovered security loopholes from time to time and it is essential that your devices can fight back the malicious viruses and malware.
  1. You can use VPN softwares which will allow your device to change its IP address and prevent the hacker from detecting your device and attacking it.
  1. If you are working on sensitive information which could be related to work, then you may choose a VPN option called “split tunneling”. This will allow the division of data transfer channels. Here, one channel of VPN will be used to work on the sensitive information and the other will be the public network and will be used for personal, non-sensitive work. But for proper isolation, it is recommended to solely use one VPN channel for all your work, both sensitive and non-sensitive, and not use the “split tunneling” functionality.
