Content filtering for WiFi hotspots enables businesses and organizations to enhance their online security profile by controlling the content that guests, customers and employees can access from their mobile devices. By preventing access to websites likely to contain malware and ransomware, organizations not only protect their wireless networks from online threats, but also the devices that connect to them.
In addition to enhancing their security profiles, businesses and organizations can also take advantage of content filtering for WiFi hotspots to conserve bandwidth, improve the customer experience, and increase productivity in the workplace. The benefits of content filtering for WiFi hotspots not only make good security sense, but good commercial sense as well.
Why Implement Content Filtering for WiFi Hotspots?
Businesses and organizations provide a public Internet service in order to attract customers who want to stay connected with family, friends and colleagues. Decisions on where to eat, where to shop and how to travel can often be influenced on the availability of the Internet. Consequently public WiFi hotspots are more frequently appearing in bars, restaurants and hotels, in shopping malls, and on public transport.
Other places of public access have also introduced public WiFi hotspots. Hospitals, libraries and schools provide wireless Internet networks for patients, visitors and students; while many employees also enjoy the convenience of their employer´s WiFi network when the employer has a BYOD policy. However, providing an unfiltered WiFi service can lead to users inadvertently downloading malware and ransomware, and exposing others to inappropriate online content.
With no control over what online destinations can be accessed via a wireless network service, Internet users are at risk of visiting a compromised website or responding to a phishing email. Internet users, who prefer the anonymity of a public WiFi service, are more likely to visit websites containing inappropriate online content; while employees have access to non-work related websites and video streaming websites that use up significant bandwidth and deny Internet access to colleagues.
Implementing content filtering for WiFi hotspots can help avoid these issues. By controlling the online environment, businesses and organizations can provide a malware-free and family-friendly browsing experience. Inappropriate online content can be blocked to risk exposure to minors and other vulnerable members of society, while employers can restrict access to non-work related websites and video streaming websites in order to enhance productivity and ensure the Internet is accessible to all employees.
How WiFi Hotspot Internet Filters Work
WiFi hotspot Internet filters work by preventing access to online threats and unwanted content. They do this using a system of unified threat management that can be configured to suit an organization´s needs. This is typically a three-tiered mechanism that comprises of blacklists and SURBL/URIBL filters, category filters and keyword filters. The first-tier defenses are updated by the filtering service provider whenever new threats are identified. Websites are also categorized automatically as they are published.
- Blacklists block access to websites identified as harboring malware, while the other first-tier defenses (SURBL and URIBL filters) prevent network users visiting websites with IP addresses from which spam emails have originated or those who hide their true identity behind a proxy server or the whois privacy feature.
- Category filters can be applied by system administrators to prevent access to specific categories of Internet content. More than three million of the world´s most-visited websites are sorted into fifty-three categories (travel, online shopping, adult content, etc.) that can be blocked with the click of a mouse.
- Keyword filters control access to websites containing specific words so that administrators can prevent access to certain types of Internet content without blocking an entire category. Keyword filters can also be configured to prevent network users downloading file types with specific extensions commonly associated with malware.
When network users type a URL or click on a hyperlink, WiFi hotspot Internet filters check each request to visit a websites against their filtering parameters. If a network user is attempting to visit an unsafe or prohibited website, access is denied and a message is displayed on the user´s device explaining why. If justifiable access is required, system administrators have the options to use a “whitelisting” facility or “cloud keys” to override the filters´ settings.
Web filtering for WiFi hotspots allows for the filtering parameters to be set by individual user, user group or universally. They can also be set within certain times. If, for example, your business or organization wants to control access to social media platforms to everybody except your marketing department, access could be allowed for one user group and denied to everyone else until after their working day is finished.
Conserve Bandwidth and Improve the Customer Experience
It was mentioned above how bandwidth could be limited in the workplace to ensure Internet access was available for every employee. The workplace is not the only example of how bandwidth issues can be resolved by content filtering for WiFi hotspots. In any location where there might be a large volume of long-term Internet users – hotels, hospitals and libraries for example – bandwidth can be limited to prevent just a handful of users placing excessive demands on an organization´s service.
By monitoring bandwidth, organizations can often identify when a device connected to their network is infected with malware from another source. Usually the tell-tale sign is high bandwidth consumption during periods of low bandwidth activity – for example reading emails. Organizations can advise their guest that action is needed to remove the malware from their device – often preventing the malware from spreading to the wireless network other gusts´ devices connected to it.
In addition to providing a browsing environment free from malware and exposure to inappropriate content, organizations can take advantage of WiFi hotspot Internet filters to improve the customer experience. This can be done via reports generated by the filters that reveal guests´ online activities. Using this information, organizations can tailor promotions and special offers to match the interests of their customers, gaining a competitive advantage over other organizations in the industry yet to implement content filtering for WiFi hotspots.
WiFi Hotspot Internet Filters in the Workplace
WiFi hotspot Internet filters in the workplace offer a series of benefits to organizations that provide a wireless Internet service for employees. Primarily, being able to control access to non-work related websites during working hours can prevent “cyberslacking” and enhance productivity. Content filtering for WiFi hotspots in the workplace can also prevent resentment between colleagues.
Several legal issues can also be avoided by the implementation of content filtering for WiFi hotspots in the workplace. Downloading copyrighted files from P2P file sharing websites or exchanging images of child pornography on the Internet is illegal under federal law. If an employee was using an employer´s wireless network to conduct his or her illegal activities, the employer could be considered complicit.
A further potential problem is when employees are exposed to objectionable online content depicting racial abuse, religious intolerance and sexual prejudices. When a hostile workplace environment is allowed to persist, those offended by the objectionable online content are entitled to claim compensation from their employer for failing to provide a safe place of work.
