LibreOffice has four different macro security levels that cover security – from no restrictions to highly restrictive. Each level has its merits.

High: This is the “hands off” level. Only signed macros from a trusted source, or macros from trusted file locations, are allowed to run. All others will have their macros disabled. You have no choice; you are never prompted. This is a level where you don't want the end users making the decisions, but you want LibreOffice to make the decision for them. | High: This is the “hands off” level.

+ | Faible : c'est le niveau « Sans sécurité ». Toutes les macros sont exécutées sans vous poser de question. Elles peuvent tourner sans que vous le sachiez, elles peuvent endommager vos fichiers et vos réglages. C'est comme marcher pieds nus sur un nid de serpents : vous serez mordus. Le seul cas où ce niveau aurait un sens, c'est sur un ordinateur qui est complètement isolé d' | ||
+ | |||
+ | Moyen : c'est le niveau « Êtes-vous sûr ? ». Avec le niveau moyen de protection, le document lancera une macro si elle vient d'une source sûre - on en parlera plus bas - sans vous poser de question. Si le document ne vient pas d'une des sources sûres, LibreOffice vous demandera si les macros du document peuvent être lancées. Vous avez le choix : Oui ou Non. Je vous donnerai plus loin des recommandations pour prendre votre décision. | ||

- | File Locations: No matter what level you use – except Low – I recommend you define at least one trusted file location. You need at least one place where you can run proven files with macros without having to OK a prompt. Don't use a location where you usually download files from email or the Internet. Use a location where you collect and save documents you need to keep. Sometimes, two or three locations are helpful. Also, make sure the location isn't too general, like your home folder. | + | File Locations: No matter what level you use – except Low – I recommend you define at least one trusted file location.

Never, ever use Low. No, I mean NEVER. Don't try to argue that you know what you are doing, and you have a firewall, anti-virus, and malware protection. Don't do it! No. No Low level setting. Go there now in your copy of LibreOffice and change it to something else. There. Now, don't you feel safer already? Now, we can calmly discuss the benefits of the other levels. | Never, ever use Low.

Take these steps when receiving a new file. Open the file from an untrusted file location, but do not allow the macros to run. Examine the macros in the document. If you have any questions about the macros, asks the person who sent the document. If they cannot give you a satisfactory answer as to why the macros are there, eliminate the document. Chances are, they are not your friend and do not have your best interest in mind (or their computer is infected with a virus). Yes, this may all sound a little paranoid, but better safe than losing time and data. If the document is clean (no macros) or the sender gives you a satisfactory reason for the macros, move the document to a safe file location. | Take these steps when receiving a new file.

- | While macros are useful, people also use them for malicious purposes. LibreOffice provides you with four different levels of protection against malicious macros. You should never use the Low level setting, but the Medium level is good for most home computers and networks. High and Very High are good in office environments where you need to control the end users interaction. Always take precautions when dealing with documents coming from other people. Sometimes, people unknowingly pass on documents that contain malicious code. | + | While macros are useful, people also use them for malicious purposes.
