IT Security Network – what is it?

Network security

Network security is an essential component for any business (unless you’re completely paper-based!).  It’s implemented to detect and prevent unauthorised or malicious users from accessing your business assets. This ensures that business continuity is not uncompromised. This type of security is necessary to prevent a hacker from accessing data inside your network/infrastructure. It also acts as a barrier to stop hackers affecting your users’ ability to access the network to deliver service.

Businesses have increased the number of endpoints (ways in which users access the network) so IT Network security has become increasingly important.  With more homeworking it’s critical that you take steps to secure your business assets.

Internet security

Internet security involves the protection of information that is sent and received in browsers.  You may think this doesn’t apply but with migration to cloud-based solutions and web-based applications, it’s more important that you may think. Internet security protections are designed to monitor incoming internet traffic. This protection may come in the form of firewalls, anti-malware, and anti-spyware.

Endpoint security

Endpoint security provides protection at the device level. By devices we mean mobile phones, tablets and laptops for example. Endpoint security will prevent those devices from unintentionally accessing malicious networks that may be a threat to your organisation. Advanced malware protection and device management software are examples of endpoint security.

Cloud security

So much has moved to the cloud, which means your users are connecting directly to the Internet, and are not protected by the traditional security stack. Cloud security can help secure the usage of software-as-a-service (SaaS) applications.  There are number options for cloud security so just reach out and we’ll get more technical!

Application security

With application security, applications are specifically coded at the time of their creation to be as secure as possible, to help ensure they are not vulnerable to attacks. Therefore, it’s important to keep versions up to date and we can automate that for you through our Monitoring and Maintenance services.

IT Network Security FAQ | Webroot DNS Protection

Traditional perimeter network defenses are focused on internet traffic coming into your network, but a lot less concerned with what’s going out. DNS Protection corrects this imbalance (and security risk) by using cloud-based, hardened DNS resolver servers to instantly check and filter all outbound internet traffic, regardless of the network source.
It leverages Webroot’s industry-leading BrightCloud® IP Reputation and Web Classification threat intelligence services to help you manage the enormous risks associated with each individual network internet request. DNS Protection is able to instantly block outbound requests from accessing highly suspicious, malicious, and high-risk destinations, significantly reducing a network’s exposure to known threats.
Yes. While endpoint protection features an effective Web Threat Shield for blocking low-reputation URLs and checking in real-time clicks to suspected phishing sites, it does not filter internet bound traffic based on website category. Its protection focuses on requests made through web browser applications. This means application-based, unknown, or those attacks bypassing endpoint protection defenses designed to reach out and communicating with the internet to download malware or other compromises are not accounted for. Many system-level ‘outbound’ internet requests are not filtered by endpoint or any other perimeter protection. DNS Protection provides an additional defense layer that ensures ALL requests are filtered by destination. This traffic check allows administrators to apply internet destination policies based on categories hand-picked by the administrator, customisable by user, user group, IP address, or site.
Yes. When you use our DNS Protection agent, your users are fully protected when they connect to other networks, even if those environments are IPv6. This is particularly important when you consider Google’s report that nearly 25% of the traffic they see comes across IPv6.
Yes. Webroot DNS Protection is located at a number of secure datacenters across the globe. It uses hardened DNS resolver servers to fend off DNS- based attacks. The hardened architecture also offers a highly resilient and reliable access to the internet.
Yes. Social media is an optional category that can be restricted, in addition to many others.
Yes. URL category policy control may be applied to specific, individual devices.
Yes. For employees on Windows devices, there is an additional agent installed through Webroot endpoint protection that ensures all their internet requests are routed through DNS Protection, even if they are connecting to an external network utilizing IPv6.
No. All the tests we have conducted, and with the architecture we have in place, DNS Protection is far more likely to actually speed up your connection. The location of your network and the DNS Protection resolver servers may have a bearing on speed, but it’s likely to be a positive one.
Yes. Streaming media and downloading content from peer-to-peer networks can consume considerable bandwidth. DNS Protection can block these sites to improve performance. This is particularly valuable for offices or locations with limited bandwidth, as well as during times when there is high demand for streaming video (i.e., during major sporting events).
Yes. DNS Protection is the only DNS filtering security solution to currently support both IPv4 and IPv6 DNS traffic filtering.
Yes, it does. By restricting sites that consume significant data like streaming, music, and torrent sites, data usage drops significantly. In particular, this helps minimize costs for data overages.
Yes. As guest devices on your guest WiFi network are not managed by your administrator, the ideal way to control content is through DNS filtering. Internet access can then be tightly controlled by limiting access to designated website categories, blocking inappropriate behavior and content.
DNS Protection provides complete visibility of all internet requests, sites accessed, and blocked malicious traffic with easy-to-use reports.
Yes. DNS Protection will filter out web sites based on 80 customisable URL categories to suit any HR, compliance, or duty-of-care requirements.
