Update The Firmware with Every Release<\/h2>\n<p>If you only take away one thing from this article, it\u2019s this. And this recommendation doesn\u2019t just apply to firewalls, but all networking infrastructure. Most Sophos Firewall OS firmware updates include important security fixes. The best way to harden the firewall is to ensure it\u2019s running the latest firmware. For Sophos Firewall, we just released <a href=\"https:\/\/partnernews.sophos.com\/en-us\/2023\/02\/products\/upgrade-your-sophos-firewalls-to-v19-5-mr1\/\" target=\"_blank\" rel=\"noopener\">v19.5 MR1<\/a> which includes a number of great new features, a significant performance boost, and several fixes.<\/p>\n<p>You can always find the latest firmware release on the firewall device by simply navigating to <em>Backup and Firmware &gt; Firmware <\/em>(as shown below).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6031 size-full\" src=\"https:\/\/partnernews.sophos.com\/en-us\/wp-content\/uploads\/sites\/3\/2023\/03\/image001.png\" alt=\"\" width=\"1432\" height=\"983\" srcset=\"https:\/\/partnernews.sophos.com\/en-us\/wp-content\/uploads\/sites\/3\/2023\/03\/image001.png 1432w, https:\/\/partnernews.sophos.com\/en-us\/wp-content\/uploads\/sites\/3\/2023\/03\/image001.png?resize=300,206 300w, https:\/\/partnernews.sophos.com\/en-us\/wp-content\/uploads\/sites\/3\/2023\/03\/image001.png?resize=768,527 768w, https:\/\/partnernews.sophos.com\/en-us\/wp-content\/uploads\/sites\/3\/2023\/03\/image001.png?resize=1024,703 1024w\" sizes=\"auto, (max-width: 1432px) 100vw, 1432px\" \/><\/p>\n<p>In Sophos Central, simply click the download arrow for the firewall you want to upgrade and choose \u201cSchedule Upgrades\u201d.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6032 size-full\" src=\"https:\/\/partnernews.sophos.com\/en-us\/wp-content\/uploads\/sites\/3\/2023\/03\/image003.png\" alt=\"\" width=\"1430\" height=\"745\" srcset=\"https:\/\/partnernews.sophos.com\/en-us\/wp-content\/uploads\/sites\/3\/2023\/03\/image003.png 1430w, https:\/\/partnernews.sophos.com\/en-us\/wp-content\/uploads\/sites\/3\/2023\/03\/image003.png?resize=300,156 300w, https:\/\/partnernews.sophos.com\/en-us\/wp-content\/uploads\/sites\/3\/2023\/03\/image003.png?resize=768,400 768w, https:\/\/partnernews.sophos.com\/en-us\/wp-content\/uploads\/sites\/3\/2023\/03\/image003.png?resize=1024,533 1024w\" sizes=\"auto, (max-width: 1430px) 100vw, 1430px\" \/><\/p>\n<h2>2. Enable Hotfixes<\/h2>\n<p>Occasionally, patches for vulnerabilities and other security fixes are released between regular firmware updates. This is done by applying hotfixes to the firewall automatically so its vitally important that this feature be enabled on all firewalls. While it\u2019s enabled by default, some customers and partners have disabled this. If you are one of those, it\u2019s highly recommended you go back and turn this feature on. This feature is found by navigating to <em>Backup and Firmware &gt; Firmware<\/em> \u2013 check that \u201c<em>Allow automatic installation of hotfixes<\/em>\u201d is enabled (as highlighted at the bottom of the first screen shot above).<\/p>\n<h2>3. Limit Access to Firewall Services<\/h2>\n<p>Sophos Firewall offers a number of ways to limit access to services that are not required to reduce exposure on the WAN. You should periodically check the device access settings and ensure that all unnecessary services are disabled (unchecked) on the WAN (see screen shot below). In particular, it\u2019s strongly recommended that you disable remote admin via HTTPS and SSH, as well as the Captive Portal and User Portal on the WAN. Use Sophos Central, VPN or ZTNA to manage firewalls remotely.
