HfL Firewall Maintenance

RM are planning to perform important maintenance to the HfL firewall on 30th August 2019 between 4.00 AM and 7.00 AM UK time. We are not anticipating any service interruptions during this change but should you experience any issues, please contact the Service Desk.

Google issue from 29th January

Following on from the Google search issues that occurred last month, RM have provided HfL with a report on this incident.

Report Summary 

On 29th January 2019, users reported issues accessing Google search results when using SSL proxies (wf3.thegrid.org.uk etc.). While trying to access search results, users were not receiving the desired webpage, instead they were getting a filtered message.

When dealing with a non-Herts eSafety query, the RM Service Desk added a new deny rule into the RM Global List (RM Pornography) within RM SafetyNet. This resulted in denying all the Google URL’s containing the rule. The change was applied to the live environment after being tested. Whilst the initial rule was overly broad, it was implemented quickly with a safety first approach as the video on YouTube was of a highly offensive nature. Following analysis and fault detection, this entry was updated to a more surgical approach, allowing for normal google search access to resume.

Follow-On Actions: The RM Management Team will discuss and finalise further safety measures that needs to be taken when staff amend the RM Global Lists. RM Management will also review the current testing scenarios and propose amendments if required.  Additional training will also be delivered to the RM Service Desk and they will be reminded of the importance when amending rules on the RM Global Lists.  HfL have requested RM keep us updated on developments.

New NAT IP address range

Collectively we have exhausted the subnet  that RM have previously set aside for NATs: 185.192.228.0/22.  RM have now provided us with this additional range: 62.171.224.0/22.

Please note that these IPs will only be used by RM when creating firewall rules on behalf of HICS schools – and not for their ‘core customers’. Further information can be found here: https://hics.hertsforlearning.co.uk/ip-addresses/public-facing-ip-addresses/

Thanks for your ongoing support and if I do not post again before Christmas, I hope you all have nice break.

Regards,

The HICS Team
