Emergency service access restriction message. How to restrict access to “secret” information on your computer. How to get rid of the “Access restrictions have been changed” notification on an Android smartphone

Hello dear readers. Today we are starting a series of articles devoted to restricting access to information on the Windows operating system.

From today's publication you will learn, how to restrict access to folders and files using Windows itself, and we’ll talk about special programs that do the same in the following articles I wrote.
Let's start with the innate talents of MicroSoft's brainchild.

Restricting access to files and folders using built-in Windows tools.

A prerequisite for the restriction to apply is the presence of several accounts in the system, not with administrator rights, and also that the file system on the disks conforms to the NTFS format.
In other words, the administrator, for other users without administrator rights, sets restrictions on writing, reading, etc.
Through an account with administrator rights, the properties of the desired folder indicate those users who will have access to it. If a user without rights tries to access a folder, a password will be requested.

Changing group access rights [deny]:

So, let's restrict access using bans. To do this, right-click on the desired folder or file and select - “ Properties", then go to the tab - " Safety" and on this tab click the button - " Change».

Next, a window opens where we click on the button “ Add" Here, enter the names of the selected objects (logins/user names), which will then be denied access to the folder. Then click " Check names" to make sure you entered the name correctly:

To deny access to all users, enter the name " All"(letter case is taken into account), the system will understand. Then in the column " Prohibit"Tick the boxes that you want to ban and click "OK"
As a result, the users you specified will not be able to access the specified folder or file, but only if they log in to the system using their account. Just so you know, if someone logs into the system, for example, from a flash drive with administrator rights, he will have access to the folder and all its contents.

Changing group access rights [permissions]:

Now let's limit access to the folder not by prohibiting it, but rather by opening rights only to certain users.
To do this, we will remove all users from the access list and add only those we need there.
It is possible that when you try to delete an element, an error will be thrown, since by default they are inherited from the parent directory. Therefore, click “ Additionally -> Change permissions..." and uncheck " Add permissions inherited from parent objects»
In Windows 10, click " Additionally"Next click the button" Disable inheritance".
The system will ask " Add" or " Delete" In Windows 10, the system will also give you two options to choose from - " Convert inherited permissions to explicit permissions on this object" And " Remove all inherited permissions from this object". I think everything is clear here. Having added the desired user, we already check the boxes in the column " Allow».

Let's summarize

So, today, dear readers, we have considered the first possibility of restricting access to certain folders and files using built-in Windows tools. This method is not the most reliable, but it is suitable for protecting “secret materials” from the prying eyes of inexperienced users.
In the next post, we'll look at another Windows feature built into the system by default that allows you to encrypt valuable data and thus limit access to it. This is EFS (Encrypting File System) - a file-level data encryption system in Windows operating systems (starting from Windows 2000 and higher), with the exception of “home” versions.

Of course, it would be nice to be able to restrict any application's access to your personal data. If you really want to do this, then our article will definitely be useful to you. However, this only applies to those users who have the Android 4.3 operating system installed on their device. It was in the latest version of this OS that one very interesting function appeared that allows you to manage any application. Don't be surprised that you've never seen it in your home. It is hidden from the eyes of users, but today we will tell you how to find it and how to start using it.

This option is called “Application Operations”; it is not even an option, but a specific program. Only it is not listed in the list of other applications. It can only be called in two ways.

The first way is using an alternative launcher. We advise you to use Nova Launcher. And here's what you need to do:

1. First, find an empty space on your desktop and tap on it to bring up a submenu. From everything listed in it, select “Shortcut”:

2. From all the available shortcuts, you need to select “Current actions”:

3. From the action list, click on “Settings”:

5. And already in these settings you can find the option or program “Operations in applications”. Click on it.

After this, a shortcut called “Settings” will appear on your desktop. By clicking on it, a window with a program for managing applications will always open. In addition, you can now manage all permissions of any application.

The second way to access the Application Actions program is to use a simple utility called QuickShortcutMaker. It can be found and downloaded in the Google Play Market application store.

Then you install this utility, run it and find an item called “Settings”. You can find it in the very first “Actions” tab in the main menu of the program. In these settings, you can again find the line “Operations in applications”. By clicking on it, a shortcut to this option will appear on your desktop, after which QuickShortcutMaker can be removed, but the shortcut will still remain.

As for the program itself for managing permissions in applications, it is quite easy to use, because its menu is, in principle, intuitive. In total, the menu contains four tabs: “Location”, “Personal data”, “SMS/MMS” and the device itself, which contains lists of all installed applications. Next, you find and select any application you are interested in to limit its access to your data, etc. And then you set the desired restrictions yourself.

As you can see, everything is very simple. It's strange that no one announced this feature. Most likely, this program is still under development, and in the future it will be improved along with the entire application management system.

It is possible that users may encounter the following situation: they have restricted some actions for the application, but the application itself has no idea about this. In the future, when you launch this application, some failures and errors may appear, so that correct operation will not be possible.

Another thing missing from this program is that it itself notifies the application that this or that feature is disabled. It may also be that some users will forget that they disabled something and will think that the application itself is to blame.

I would like to note that a similar option has already been implemented and is used in the alternative firmware CyanogenMod, and its operation does not require any serious modifications.

Under Android it says “Access restrictions have been changed”

"Access restrictions have been changed." This message is often seen on their screens. smartphone owners of devices from the Moto X, Moto G and Nexus model families. This alert appears every now and then in the notification slider and then disappears. Moreover, the problem is not caused by an error in the software or hardware of the Android device, it is just a simple message from the emergency call function on phone e. Despite the fact that this notification is absolutely harmless, it annoys users and even scares them. Indeed, for uninformed people, the phrase “Access restrictions have been changed” can mean anything - including blocking data transmission or voice service.

The notification also pops up when the network changes, i.e. from 2G to 3G or 3G to 4G and vice versa. And all this mainly appears when using mobile data and disappears when connected to a Wi-Fi network. In general, the main problem is the loss of the network or switching from 3G to 2G - for users who need a mobile network with high-speed data transfer capabilities.

How to get rid of the "Access restrictions changed" notification on Android smartphone e?

Method 1: Block receiving notifications on phone using a third party application
Before using this method, check to see if your Android device has a built-in feature to turn off notifications. This feature may be available for smartphone with Android 5.0 Lollipop and 6.0 Marshmallow, but some versions of the system may not provide access to it.

What to do if a smartphone or tablet running Android says “Access restrictions have been changed”

Very often a situation arises when several people work at a computer and it is desirable that access to the personal files and folders of each user be limited to other users. You can deny access altogether, or you can limit it: for example, one user needs full access, another needs read-only access, and some are denied access altogether.

Each of you probably understands why to do this even without my prompting. Here's how it's correct restrict access to files in Windows 7, not everyone knows. Therefore, we will analyze this process in great detail.

restricting access to files and folders in Windows 7

To begin with, of course, we need to decide on the object to which we will restrict access. So, we selected a file or folder and proceed according to the following algorithm:

1. Right-click on the object (file or folder) and select “Properties”.

2. In the window that opens, select the “Security” tab. It is here that user rights to access a specific file or folder are determined.

The top area will display all users or user groups created in the system. By clicking on a specific item, you can view and change the rights of a specific user to this object. To completely prevent a user from “touching” a specific folder or file, remove it from the top list.

3. If you are unable to delete or change the rights of a specific user, then all of his rights are inherited from the “parent”. To still be able to restrict user rights to a specific object, do the following: go back to the “Security” tab in the file properties and click on the “Advanced” button (under the section displaying user rights (see the figure above).

The “Advanced security settings” window will open:

Go to the “Resolution” tab if it does not open for you by default. Next, click on the “Change Resolution” button. Next, uncheck the “Add permission inherited from parent objects” checkbox, after reading the warning message, click on the “Add” button. And then “OK” all the time until you return to the “Security” tab of the file properties.

Now you can change user rights to access a specific object without restrictions.

access permission values

Let's look in more detail at the meaning of specific user rights:

  • Full control - everything is quite simple here: you are allowed to perform all operations on the object, including changing the permission and becoming the owner of the object.
  • Change – differs from the previous paragraph in that it is allowed to perform only basic operations with the object, i.e. reading, modifying, creating and deleting an object. Changing the permission of the current object and becoming its owner is not allowed.
  • Read and execute– speaks for itself: you can view the contents of an object and run programs.
  • List of folder contents– the same as in the previous paragraph, only regarding directories.
  • Read – only viewing the object is allowed.
  • Write – allows you to create files and write data to them.
  • Special permissions- These are permissions that are set by clicking on the “Advanced” button.
special recommendations when setting access rights to files and folders
  • I advise you to pay attention to the following:
  • If you check the checkbox for a permission with a higher priority, the checkboxes of the dependent permissions are automatically checked.
  • Setting the “Deny” permission has a higher priority than “Allow”.
  • By changing the permissions for a directory, the permissions for all sub-objects (folders and files) will also automatically change.
  • If certain permissions are not available, it means they are being inherited from the parent folder.
  • If you do not have the rights to change permissions, then all the checkboxes will not be available to you.
  • When changing permissions for groups (for example: “Administrators”, “Users”, “System”), the corresponding permissions for all users of this group will automatically change.
  • Do not change permissions for the “System” group; this may disrupt the operation of the operating system.

When changing permissions for a specific object, be careful and careful. Do not change several permissions at once; be sure to check the functionality of the system after making changes.
