问题 My application (using SDK less than 24) can take photos and video using the camera. The photos and videos can be viewed in the gallery outside the app. SDK 24 and above requires FileProvider to create the uri for saving the photo or video to the gallery. Prior to SDK 24 I would use a uri and an intent to take a photo: private void openCameraForResult(int requestCode){ Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); picturesDirectoryPhotoFileName = nextFileName(); File photoFile =

问题 Reading through the many questions regarding session hijacking here on Stackoverflow, I've gathered that the only 'solution' to validating a users session is by checking the user agent, which is such a weak layer of protection that I don't even bother to implement it. So, I was wondering what solutions you guys have implemented? Are you even using PHP's native sessions or is there a more secure solution? 回答1: You don't need the session id in order to hijack a session. An XSS attack can go 1

问题 I'm trying to avoid0 CORS preflight requests for authorized GET requests, for latency performance reasons. The simple way to do that is putting the access token in a URL query parameter, but this is a bad security practice1. According to this answer2, the goal of browsers is to block anything that couldn't already be accomplished with HTML tags like img or script . But if that's the case, why is it allowed to set headers like Accept or Content-Langage ? You can't set those on an img tag. Also

问题 I'm working on a CRM which will feature advanced authorization and the management of users in groups that have a specific role in the system. Basically, what I'd like to do is this: Manage Dynamic Authorization for (Domain) Models / Controllers / Action Manage Dynamic Authorization For Objects and Fields. I know about ROLE_xxxx in the security.yml file but I'd rather not hardcode the roles. For example, I'd like to have a sort of matrix/grid where a super administrator can create custom

问题 I've been following this tutorial to add SSH Certification to my site. However at the moment this method does not work for the time-being due to a security flaw, so here is the alternate method. I'm trying to implement the alternate code-paste: sudo certbot --authenticator webroot --webroot-path <path to served directory> --installer nginx -d <domain> however am not sure what to put in <path to served directory> . Is the "path to served directory" the nginx config? Would it look something
