Sophos Xg Firewall Home Edition

XG Firewall makes it simple to get up and running quickly with the best network visibility, protection, and response in the industry. We make it easy to protect your network across multiple sites while also enabling access for your remote workers.

Getting started

Deployment

If you just received your XG Firewall, run through the convenient XG Firewall setup wizard which will have you up and running in a few minutes with essential protection for your network.

If you are running two XG Firewall appliances in High Availability mode for maximum business continuity, then be sure to take advantage of the new Quick HA option in v18.

INSTRUCTIONS: ‘How to deploy in gateway mode’ ► VIDEO ‘Registration and setup wizard’ ►

Get familiar with XG firewall

After the initial setup, review our extensive library of Getting Started How-To videos and the Documentation for XG Firewall. There’s also a great list of articles and videos to review on the Initial Setup Community Forum.

Periodic best practices checkup

To ensure your XG Firewall is protecting your network optimally, follow these best practices after initial setup or periodically.

If you don’t have time to perform these steps, the Sophos Professional Services team of network experts is available to help ensure your firewall is configured optimally. Contact them at [email protected]

Double check your protection licenses

On your XG Firewall go to Administration > Licensing and ensure you have these essential network protection subscriptions:

  • Network Protection – Essential for IPS, advanced threat protection, and botnet protection
  • Web Protection – Essential for web security and control and application control
  • Sandstorm Protection – Essential for the latest threat protection using artificial intelligence and sandboxing analysis
  • Email Protection – Essential for anti-spam and phishing attack protection
  • Web Server Protection – Essential if you have any servers that require public internet access

Update firmware

Always keep your firmware up to date to ensure you have the latest security, performance, and reliability updates. You can get the latest v18 release for your XG Firewall from MySophos.

Firewall rule and protection policy recommendations

Of course, by design, your firewall blocks all network traffic – your network is completely locked down – but you enable traffic to flow by creating firewall rules.

Firewall rules enable your network to function, but they also create opportunities for hackers, ransomware, and malware to enter. Hence, it’s essential to protect your network by applying security policies to these firewall rules.

If you’re new to XG Firewall or v18, check out the introductory video on Firewall Rules and the What’s new in v18 for Firewall Rules video.

If your firewall has been running for a while, you may have dozens or even hundreds of firewall rules you’ve added over time. It’s very important that you periodically review all your firewall rules to ensure that there are no avoidable “openings” in your network. Ensure you don’t have any unnecessary or unused rules that are presenting openings that hackers can take advantage of.

Start by checking the ‘Active firewall rules’ widget on the Control Center to identify unused rules:

Then, go through your firewall rules to examine all the active rules to ensure they are needed and proper protection is being applied.

Sophos Xg Firewall Home Edition Review

In particular, disable all non-essential port-forwarding rules, and re-evaluate if any of the port-forwarding rules you have can be better accommodated via VPN access or, at the very least, multifactor authentication.

Exposed services and servers through port forwarding are one of the top ways hackers breach your network. VPN and MFA provide much better security for remote access to internal network resources.

If you are on v17.x we suggest you upgrade to v18 for the latest NAT rule enhancements. If you are on v18 already, review all your NAT rules to ensure all are required and adequately protected by a corresponding firewall rule.

Make sure you’re applying essential protection to all your firewall rules. XG Firewall makes it super easy to assign web protection and control, intrusion prevention (IPS), sandboxing, and file analysis as well as application control.

In general, do not apply “Allow All” or “None” when selecting a protection policy. These should only be used in special circumstances or for troubleshooting, never as an active protection policy.

Recommended protection best practices

TLS Inspection

Most internet traffic is encrypted with SSL/TLS making it impossible to secure without proper inspection.

XG Firewall v18 introduced the new Xstream TLS Inspection feature that provides high-performance inspection of encrypted traffic, enabling you to properly protect your network. Ensure you have one or more TLS inspection rules applied to your internet traffic, otherwise a lot of the protection discussed below will be ineffective. (Instructions: ‘SSL/TLS inspection rules’ / Video: ‘Xstream SSL inspection in XG Firewall v18′).

You will need to deploy the XG Firewall SSL certificate on your client machines, which is accomplished easiest on Windows using the wizard in Microsoft’s Group Policy Manager.

After deployment, monitor TLS inspection via the Control Center and add important problematic sites to the exception list with the convenient tools available from the widget.

Web policy and protection

This determines which websites are allowed or blocked and how to protect web traffic. Any firewalls governing internet traffic should have a web filtering policy in place.

There are several built-in policies for schools, workplaces, and more that you can use out-of-the-box to make this easy. Simply choose one appropriate for your organization and customize it to suit your needs. (Instructions: ‘How to implement Web Protection’ instructions / Video: ‘How To: Creating Web Protection rules’).

Malware and content scanning

XG Firewall can scan all web traffic for malicious code and downloaded files.

We strongly recommend that you take advantage of SophosLabs Threat Intelligence and Sophos Sandstorm sandboxing to further analyze files.

To do so, simply check the option to “Detect zero-day threats with Sandstorm” for all rules governing web traffic. (Instructions: ‘How to configure Sophos Sandstorm’).

IPS

Intrusion Prevention looks for activity attempting to exploit vulnerabilities in networked devices. This is a common technique for hackers to get control of servers exposed to the internet and to move laterally within a network. IPS protection signatures are included for all platforms: Windows, Macs, Unix, and more.

Make sure you are applying IPS protection policies that align with the network platforms in your environment – use either one of the built-in policies or create your own. Also, ensure you not only apply IPS protection to internet traffic rules but also rules between different segments of your internal network (e.g. LAN and DMZ) to help catch active threats trying to spread on your network. (Instructions: ‘IPS policies’ / Video: ‘How To: Setting Up And Configuring IPS’).

ATP

Sophos Xg Firewall Datasheet

Advanced Threat Protection is another essential aid in identifying an active threat on your network. It examines outbound traffic for any attempts to contact known hacker command and control servers.

If an ATP is detected, it indicates you have a bot or threat on your network. ATP setup is super easy. (Instructions: ‘How to configure Advanced Threat Protection (ATP)’).

VPN connectivity recommendations

Sophos Xg Firewall

With VPN connections being tremendously important these days, here are some additional resources on getting the most from your XG Firewall’s VPN connectivity options.

Site-to-Site VPN: If you want the ultimate in VPN reliability and security between your central office and branch offices or remote locations, Sophos unique RED tunnels are ideal.

You can easily deploy an XG Firewall to a remote location without touching it and set up a RED tunnel in no time. (Instructions: ‘Substituting XG for RED devices via Light-Touch deployment from Sophos Central’).

Remote user VPN: If you have users working remotely, XG Firewall offers a couple of options for secure remote access.

Sophos Xg Firewall

Our previous article outlined the various access options and their pros/cons. We recommend using Sophos Connect Client for the ultimate in ease-of-use. (Instructions: ‘Sophos Connect Client’ / Video: ‘Sophos Connect VPN Client’).
