Mandatory SonicOS firmware upgrade for your firewall
Upgrade the SonicOS firmware on your firewall today
In the past, Dell SonicWALL used industry standard 1024-bit certificates. To comply with Certification Authority/Browser forum requirements based on NIST Special Publication 800-131A, as of January 1, 2014, all web browsers and Certification Authorities (CAs) will no longer sell or support 1024-bit RSA certificates. Certificates with less than 2048-bit key length will need to be revoked and replaced with certificates of higher encryption strength. All current Dell SonicWALL firewalls use versions of SonicOS firmware with the 2048-bit security standard. Recent updates and upgrades of SonicOS firmware use the industry standard and recommended 2048-bit certificate. This is an urgent notification that on January 1, 2014, all web browsers and Certification Authorities (CAs) will no longer support 1024-bit RSA certificates. This change is not driven by Dell SonicWALL, but rather a decision by Certificate Authorities to enforce the use of highly secure certificates. Certificates using the 1024-bit key length will be revoked and must be replaced with certificates of higher encryption strength. If you own a Dell SonicWALL firewall with an older firmware version that does not use 2048-bit certificates you must upgrade the firmware to the latest version or the minimum General Release version which includes the 2048-bit certificate as listed in the Firmware Upgrade Table below by December 31, 2013. Dell SonicWALL is providing the minimum firmware upgrade to all customers regardless of support contract status.
How does this issue affect me?
If you own a Dell SonicWALL firewall with an older firmware version that does not support 2048-bit certificates, the firewall will NOT be able to get real-time license information or the latest security services updates from our back-end systems. Existing security services on Dell SonicWALL firewalls that use 1024-bit certificates will continue to block previously-known threats, but the lack of updates may expose the protected network to new threats and exploits. In addition, you will NOT be able to activate and renew security services.
