This section is found in the 'cog wheel' menu in the UI, with changes in UI16 and the 'Next Experience' UI. This information applies to both UI16 and the Next Experience UI. 'Allow Notifications' (Next Experience): This toggles the Notification[sys_user.notification] field on or off. 'Notification Channels' (UI16) or 'Delivery Channels' (Next Experience): It allows you to define extra Notification Channels apart from the default email address on the user's sys_user record. These include secondary email addresses, mobile numbers for SMS notifications, and a special 'Push' notification channel created when logging in from the mobile app, which references a sys_push_application record. Create notification channels 'Notifications by Category' (UI16) or 'System Notifications' (Next Experience): This is a list of all email Notifications defined in Notifications[sysevent_email_action] table. It allows the user to selectively disable these Notifications for any Notification Channels they've defined. By default all of these are 'on' for the default Notification Channel, and off for other channels you've defined. The catch with this is that it only controls 'normal' Notifications, i.e notifications that are sent to you because an administrator put you into the recipient list in one of the notification's Who will receive->user/group/... fields in a Notifications[sysevent_email_action]. This means that turning a Notification 'off' here will mean that you won't receive that Notification even if you are in the notification's user/group/... fields. And turning the Notification 'on' means that you will receive the Notification, *but only* if you are also in the notification's Who will receive->user/group/... fields. Changing things here creates/edits records on the Recipient Notification Preferences[sys_recipient_notif_preference] (previously the Notification Messages[cmn_notif_message] table). Admins can also override some of this functionality by making Notifications forced or mandatory using the Forced delivery option on the Notification: Make a notification mandatory Force a notification to be sent 'Personal Notifications' (UI16) or 'Custom Notifications' (Next Experience): You can click 'Create Personal Notification' to create a subscription to a particular Notification, as long as that Notification has Subscribable=true (Create Personal notifications). A subscription means that you will receive the Notification even if you're *not* on that Notification's Who will receive->user/group/... fields. 'Personal Notifications' (i.e subscriptions) are records on the Notification Subscriptions[sys_notif_subscription] table. You can optionally put conditions on subscriptions. The ISC - Security 'Subscribable' Notifications Introduced in Rome In general we don't recommend changing or disabling these notifications, they're designed to notify about events that might be important for security (failed logins, high privilege user impersonated and so on). They should be 'subscribable' only, so nobody should get them OOB, only if they've subscribed to the notifications using these steps: Set preferences for security event notifications But if you want to disable them though you can set a custom ACL using KB0997437: How to hide ICS - Security Notification category.
