Android data security. Security Certificate Issues on Android (Problem Solving)

It's no secret that the Internet is something ordinary for us. However, do not forget that attackers also use it for their own purposes: they steal users' personal data and send spam. The browser is the main application for accessing the Internet, it can also be called the first line of defense. This is what prompts developers to create new tools to protect a computer from network threats, and sometimes from imprudent users themselves. After all, as they say, the main cause of a computer breakdown sits opposite it. Below we will talk about one of the Yandex.Browser protection systems - Protect. What is it, how to enable and disable this mode.

Protected mode - what is it and what is it for

To ensure the security of your computer, Yandex browser uses active protection technology Protect, which includes four protective mechanisms. Let's consider them sequentially.

  1. Password theft protection. The browser warns users when they start entering a password on suspicious pages.
  2. Public Wi-Fi Protection. The web surfer connects to the site using a secure HTTPS protocol, and data exchange between the user's device and the site takes place through this securely encrypted connection. An analogue of the "Turbo" mode, only the traffic is not processed or compressed in any way.
  3. Checking uploaded files. The file scan starts immediately after the download starts, namely, it highlights some file characteristics and sends them to the anti-virus cloud for scanning. If the file is dangerous, the browser will display a notification.
  4. Blocking dangerous and fraudulent sites. The Yandex search robot checks tens of millions of pages daily for malicious code and places the addresses of infected and fraudulent sites in a special database. When you try to open any of them, the browser blocks the loading of the site and displays a warning to the user.

In theory, as you can see, everything is fine. However, in reality, many are annoyed by the function that is on our list at number four. The browser quite often blocks access to sites that we have been using for a long time and we know that they do not pose a threat. A logical question arises: “Why is this happening?!”. Let's try to figure this out.

If you do not take into account the resources that are created for the distribution of malicious programs, then do not forget that the danger can also come from respectable sites. Sometimes hackers hack even very well-known sites in order to carry out their evil intentions. Blocking is also imposed as a result of oversight by moderators of the content that users post on their pages. The database of malicious addresses is replenished simultaneously with the indexing of the Internet. Therefore, getting under the Yandex filter does not take much time, it takes much more to get the site out of there.

Now that we know what the Protect function in Yandex.Browser is, we can start disabling it. However, it is worth considering: is this protection really bothering you? After all, when blocking access to the site, you can always click "Ignore this warning" and continue opening the site. If you are sure that you can independently figure out whether to trust the site or not; and these warnings only interfere with you, you can safely proceed to the instructions for disabling protection.

How to disable Protect in Yandex.Browser

  1. We go to the browser settings.
  2. Scroll to the very end of the settings window and select "Show advanced settings".
  3. Now, a little lower will be the category "Personal data". Here you need to uncheck the box next to "Turn on protection against malicious sites and programs."

    Ready. The program will no longer bother you with its annoying warnings.

    This feature is enabled in the same way.

The Protect technology in Yandex.Browser is designed to protect the user from accessing malicious sites. Turn it off or leave it on, it's up to you.

The extraordinary practicality, versatility, and ease of use of Android tablets have led to the fact that such shells have quickly spread to gadgets from well-known manufacturers. Such an OS is constantly in the process of improvement, and its most recent versions are noted by the owners for commendable, uninterrupted operation. A large number of various auxiliary programs make the tablet a true assistant in many everyday tasks: applications will allow you not to forget any important event, present the interface in a special way, translate the most difficult phrases, use multimedia programs.


At the same time, due to the growing popularity of Android, the malicious creators of harmful installations and ordinary viruses do not sleep either. It is low-quality software that is the main threat to the security of the tablet. An expensive gadget can fail for a very long time without fulfilling the main requirements.

Video files have no harm in them, in the worst case, data loss will occur. But the software needs to be treated with great attention. It is recommended for future use on the tablet to install software only from official sources.

Reliable operation of the system, as well as immunity to various suspicious programs, can be provided by frequently installed upgrades. The existence of a high-quality antivirus does not harm the gadget in any way. The famous AVG Antivirus for Android can quickly prevent the installation of applications that contain some kind of threat. Loss or unauthorized transmission of information can happen due to the careless use of unsecured Wi-Fi. Passwords should always be used when transmitting sensitive information over a secure channel.

Always use personal passwords and never tell anyone about them. This common method is used to protect personal information. The password should be fairly easy to remember, but should not contain names, dates of birth, or other data that is easy to "crack through". In addition, now there is a KeePass service that can store all passwords in a high-quality and centralized manner. Android tablets are a reliable innovative device. You just need to be critical of the software and the order of using the device, and the tablet will be able to respond with a long service time.

Turn off security warnings

In certain situations, otherwise secure sites may not be able to securely submit a form (for example, a form that contains a password or bank card number). At the same time, a special program called Safari displays a warning that prompts the person to cancel the operation. If a person does not want such a message to be shown, it is possible to disable it.

For this you need:

  1. Select the "Action" menu, then "Settings" and press the "Security" key. (The action menu is located in the top right corner of the Safari window and is a gear icon.)
  2. Uncheck "Always ask before submitting an insecure form to secure sites"

If you disable these warnings, your tablet will be less protected. Sending personal data or downloading objects is necessary only in a situation of full confidence in the quality of the public site.

Risk minimization

On the Internet there is a huge number of hidden threats for tablets and operating systems from Google. But at the same time, there are some ways that help reduce the risks of such “digital infection” to an insignificant minimum.

Here are the most effective ones:

  • be sure to use a VPN;
  • download applications only from a repository called Google Play;
  • during installation, you need to pay attention to the options that will be allowed by this application;
  • create long and strong passwords;
  • to carry out authentication of especially important sites and make it multi-stage.

VPNs require special thought. This method can be used in almost any state. In addition, in China, a VPN is the only way to use YouTube and other social networks.

Strong password storage

There are special services that will help not only save multiple passwords of a person in one place, but also save them in their original, encrypted form. In other words, even assuming that crackers manage to get hold of these passwords, they simply cannot use them in any way.

Regarding two-step authentication, everything is quite trivial and simple. For example, a person has a Google account. He can set a mode during which for access you will need not only to enter a password, but also to dial a code that was received via SMS on the person’s mobile device specified in his profile.

Some services are also able to provide specially crafted applications that issue certain access codes to a person. After entering their master password, a person will need to enter a code specially created in this way, which will be active for no more than 20 seconds.

When trying to log in to a site, some of the users may encounter a message "There is a problem with this website's security certificate". In most cases, the cause of this error is a date-time failure on the user's computer, as well as spontaneous work with the certificates of some sites. In this article, I will explain what this problem with the site's security certificate is, what causes it, and how to fix it.

There was a problem with this website's security certificate - causes of dysfunction

The site certificate issue in question appears when you try to log in to a site that has a security certificate installed, but the specified certificate cannot be verified by the browser. Usually, the text of the error contains a message stating that the issuer of the certificate is not known, the certificate is self-signed (self signed) and other similar reasons (Mozilla Firefox browser differentiates this problem especially often).

Popular browsers usually contain a built-in list of trusted certificate providers (such as DigiCert). At the same time, the certificate provider for some sites may not be included in this list, in which case the browser will warn you that you should not trust the Certificate Authority that issued the certificate for this site.

Other causes of a site security certificate issue include:

How to fix "The site's security certificate is not trusted" error

Quite often, the text of this error with the wording "security certificate is not trusted" is found on the Internet Explorer browser.
