Block and unblock of attachment types in SharePoint

  In SharePoint by default few attachments are blocked and will not be allowed to be uploaded.
 If we want to allow uploading of blocked file type then we need to delete the file type from "Blocked file types".
Follow the below simple steps to allow block file types into your site in SharePoint.
  Navigate to Central Administration->Manage Web Applications->select desired web application->Blocked file types as show in figure below


And in the below window, remove the undesired file types from the blocked file types. You will now be able to add that file to your site.
Also you can add any file type extension you don’t desire to be uploaded. Just type the extension of file type you want to block in braces. Ex: if you want to block word document then type {.doc} in separate line in below window and click ok.



File types Extensions blocked by default in SharePoint 2013 are:

    Als ich neulich über Cloud-Sicherheitsarchitekturen nachdachte, fiel mir die Notwendigkeit auf, verschiedene Sicherheitsdienste zu vergleichen. AWS, Azure und GCP bieten alle ihre eigenen Ansätze zur Absicherung von Daten in der Cloud. AWS setzt stark auf IAM (Identity and Access Management), um den Zugriff granular zu steuern, während Azure mit seiner integrierten Sicherheitsüberwachung punktet. GCP hingegen bietet eine benutzerfreundliche Oberfläche und hat ebenfalls fortschrittliche Tools wie den Security Command Center integriert. Wer mehr über diese Technologien erfahren möchte, kann sich gut auf csvisor.de informieren. Um in der Cybersecurity Weiterbildung erfolgreich zu sein, sollte man sich intensiv mit diesen Plattformen auseinandersetzen und die jeweiligen Stärken nutzen. Das Jahr 2024 wird entscheidend sein für Unternehmen, die ihre Sicherheitsstrategien anpassen müssen.
