It is straightforward to implement security controls to protect wired networks, but many businesses fail to apply the same controls to improve WiFi security, often due to a lack of understanding about how to improve wireless access point security. In this post we cover some of the main threats associated with WiFi networks and explain how easy it can be to improve wireless access point security.
Wireless Access Points are a Security Risk
Most businesses now apply web filters to control the types of content that can be accessed by employees on their wired networks but securing wireless networks can be more of a challenge. It is harder to control and monitor access and block content on WiFi networks.
Anyone within range of the access point can launch an attack, especially on public WiFi hotspots which have one set of credentials for all guest users. It is therefore essential that controls are implemented to improve wireless access point security and protect users of the WiFi network.
WiFi Security Threats
A single set of credentials means cybercriminals are afforded a high degree of anonymity. That allows them to use WiFi networks to identify local network vulnerabilities virtually undetected. They could conduct brute force attacks on routers, for example, or use WiFi access to inject malware on servers that lack appropriate security. If access is gained to the router, attacks can be launched on connected devices, and malware can be installed on multiple end points or even POS systems to steal customers’ credit/debit card information.
The cyberattack on Dyn is a good example of how malware can be installed and used for malicious purposes. The DNS service provider was attacked which resulted in large sections of the Internet being made inaccessible. A botnet of more than 100,000 compromised routers and IoT devices was used in the attack.
Man-in-the-Middle attacks are also common on Wi-Fi networks. Any unencrypted content can be intercepted, such as if information is exchanged between a user and a HTTP site, rather than HTTPS, if a VPN is not used.
Public WiFi networks are often used for all manner of nefarious purposes due to the anonymity provided. If users take advantage of that anonymity to access illegal content and download child pornography or perform copyright infringing downloads of music, films, and TV shows from P2P file sharing sites, an investigation would center on the hotspot provider. Questions would likely be asked about the lack of security controls to prevent illegal website access.
The Easy Way to Improve Wireless Access Point Security
The easy way to improve wireless access point security is a web filtering solution. Web filtering solutions are usually implemented by businesses to secure wired networks, but solutions also exist to improve wireless access point security.
A web filter forms a barrier between the users of the network and the Internet. Controls can be applied to stop users from accessing dangerous, illegal, or inappropriate website content. Even if each user has their own access controls, without a web filter, users will still be vulnerable to malware attacks and phishing attempts and the hotspot provider may be liable for illegal activities over the WiFi network.
There are two ways of implementing WiFi web filtering to improve wireless access point security. One is to rely on a list of categorized domain names and use that to control content. The other is DNS-layer web filtering, which uses the DNS lookup process that is required before any user is directed to a website after entering the domain name into their browser. The DNS server turns the domain name into an IP address to allow the web page to be found.
Why DNS Filtering is Best Way to Improve Wireless Access Point Security
The main difference between the two types of web filtering is the point at which access is blocked. With a traditional web filter, content is first downloaded before it is blocked, which is a risk. With DNS-layer filtering, content is blocked during the lookup process before content is downloaded.
If content is downloaded before being blocked, this will naturally have an impact on available bandwidth. DNS-layer filtering has no impact on bandwidth, since the content is blocked before it is downloaded.
DNS filtering does not need to be integrated with other systems and it works across all devices and operating systems, since they all use DNS servers to access websites.
DNS filtering is also quick and easy to implement. No appliances need to be purchased, hardware doesn’t need to be upgraded, and no software downloads are required. A simple change to the DNS is all that is required to point it to the provider’s DNS server. It is also much easier to maintain. No software updates are necessary and, in contrast to other security solutions, no patching is required. It is all handled by the service provider.

Can I secure multiple access points at different geographical locations?
WebTitan is a DNS-based web filtering solution that sees all filtering take place in the cloud. Being cloud-based, WebTitan can be used to filter the Internet at any location, for both wired and wireless networks. You can protect multiple access points through the same solution, even if those access points are in different cities or countries. You can set controls for each access point through a single web-based user interface.
Can I set different filtering controls for employees and guest users?
With WebTitan you have full control over the content that can be accessed by all users of your access points. You can set different filtering controls for individuals, departments, user groups such as guest users, and the entire organization. You have highly granular control over the content that can be accessed, with filtering by category, keyword, and URL filtering.
Is it possible to bypass filtering on access points?
Most people will attempt to bypass filtering controls on access points by using an anonymizer service or proxy. If the Internet is accessed through the anonymizer website or proxy, the actual content viewed will not be visible via the web filtering service. To prevent users from bypassing the web filter you can block anonymizer services through the WebTitan UI.
Can I block specific websites on my access points?
You can use the blacklisting feature of WebTitan to prevent a specific website from being accessed via your access points. You can do this for the entire organization, for different departments or user groups, or for specific individuals. Conversely, you can use whitelisting to allow a website to be accessed even if it contravenes other filtering controls.
Is it possible to temporarily disable filtering on access points?
With WebTitan, you do not need to disable web filtering if you need to bypass your web filtering policies on a temporary basis. You can configure a cloud key that can be used to bypass filtering controls for a limited period and can set the duration that the cloud key is valid through your UI.
