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.
So after Instagram allows viewing photos once , Messenger has also updated the feature of sending photos that can only be viewed once, automatically deleting photos and videos as soon as the other person finishes viewing them. The other person also cannot take screenshots or view photos on Messenger on a computer. So we have another way to send self-destructing messages on Messenger without having to turn on self-destruction for the entire chat. Below are instructions for sending photos that can only be viewed once on Messenger.
How to send photos that can only be viewed once on Messenger
Step 1:
First, open the chat you want to send a photo to view once on Messenger. Then click on the camera icon to take a photo or send a video if you want. Now you can take a photo or record a video as you like.

Step 2:
After recording the video, you will see a notification about the feature of sending photos that can only be viewed once on Messenger . The other person can only view the photo once, and can only view it on the Messenger phone application, not on the computer. Messenger also does not allow forwarding or taking screenshots, click OK to use.
Step 3:
The image is then set to Single View mode and you press Send to send the image.
In case we don't want to use this mode anymore, switch to Keep mode in the chat.
Step 4:
Videos or photos can only be viewed once and displayed in Messenger chat as shown below.
The other person taps on the photo and video to view it in the Messenger app and as soon as they view it, it automatically disappears and cannot be viewed again.
If you take a screenshot, it will display a message Unable to take a screenshot on Android. With Messenger on iPhone, it will display a message like below if you take a screenshot.

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.
