Enable FIPS Mode on SLES 15 and Verify the Boot State
Follow SUSE’s SP7 procedure to enable FIPS mode, reboot safely, verify the active policy, and check whether your compliance requirement calls for validated modules.
Not supported as many services as Chorme , nor stable as Firefox , so Opera is not the most popular browser in the world. However, this browser still has changes and upgrades to serve its loyal customer base, one of which is the mute feature right on the tab in use.

In fact, this feature is completely similar to muting the web browser that Download.com.vn introduced earlier ( Safari also has this feature) and users only take 1 click to do this.
How to do it is very simple, from the interface of Opera browser, right- click on the tab watching movies, listening to music ... select down the Mute tab .

Immediately the sound will be "mute" and we can see the speaker icon with a slash (the sound is disabled). To unmute it, just right-click on the tab and then left-click on the Unmute tab to finish!
In addition, Opera also allows to turn off the sound of other tabs on the page being used without hovering and that. By right-clicking on any tab, selecting Mute other tabs.
With the instructions above, hope you can use Opera better and who knows, this will be the browser will be installed on your computer by default instead of Internet Explorer or Coc Coc ?
I wish you successful implementation!
Follow SUSE’s SP7 procedure to enable FIPS mode, reboot safely, verify the active policy, and check whether your compliance requirement calls for validated modules.
Compare YaST and cryptsetup for a new encrypted SLES data volume, choose LUKS1 or LUKS2, and verify unlock and mount behavior safely.
Create, refine, and verify a least-privilege AppArmor profile on SLES 15 SP7, with a clear note on SLES 16’s SELinux default.
Set up RMT on SLES 15, mirror entitled repositories, and verify HTTPS registration and package access from a test client.
Connect SLES 15 to AD with YaST’s SSSD-based logon management, then verify directory lookup, domain login, and Kerberos tickets.
Set up the right Live Patching path for SLES 16.0 or 15 SP7, apply eligible kernel fixes, and confirm what is active without confusing it with a reboot-required kernel update.
Load a custom SLES 15 kernel module without disabling Secure Boot. Match the running kernel, sign the .ko file, enroll a MOK key, and verify loading.
SLES 15 SP5 can migrate online to SP6, but each node must reboot. Use a tested rolling upgrade or blue-green cutover to keep workloads reachable.
Use SUSE’s supported STIG profile to scan SLES 15, test remediation, review remaining findings, and retain assessment evidence.
Trace a failed Cockpit connection through DNS, port 9090, the systemd socket, firewalld, TLS, and login settings using current SUSE guidance.
