You must also check your laptop or computer that it does not have malware, trojan malware, remote monitoring software, etc. Keep your applications and downloadable applications modified. Always update to the newest edition of your website, community, shopping trolley solution application, etc.
Do not have writable computer file authorizations. The appropriate authorizations are normally 755 or 644, and you can check these in your File Administrator. Most customers know to prevent 777 authorizations, but you really want to prevent any authorization configurations which allow Team and World writing. (That's anything finishing in 7, 6, 3, or 2. The first number can be one of these, but not either of the last two figures.)
Never keep applications on your consideration that are not being used. These are generally neglected and since they are not managed they are often out of time frame and can cause a very serious protection risk. If you are in no more need of the programs it is best to obtain your back ups and eliminate it from the server.
