Quick Heal Seqrite: practical application of MDM for full control over mobile devices

Quick Heal Seqrite
Developer: Quick Heal
Product name: Seqrite Mobile Device Management


Users' awareness of security slowly, but systematically sticks the last nails to the lid of the mobile anti-virus software coffin. But there is nothing wrong with it that would not work out. Other areas are waiting for development, such as: active monitoring of applications, controlling the functions of a smartphone, enforcing access to company resources, or separating a private and business zone. And it is precisely on the grounds of prevention (filtered & deny) that Quick Heal finds its niche

Editor's opinion


The progressive version of the Android operating system has not made it easy for developers of security solutions. With each subsequent installment, access to critical areas of the Android system is limited. The basic problem (ironically!) Is the sandbox - if the installed application tries to perform an undesirable activity, eg to gain access to private data from another application, then the separated area in which the "program A" is running will not allow access to information from " program B ', unless this operation is preceded by the deliberate use of the 0-day vulnerability and escape from the isolated memory area.

In practice, Android does not allow mobile antivirus to get higher privileges than installed programs from the official repository. As a consequence, without access to the root, you can not remove system applications, seriously infect your system, install some open-source "apps" from the alternative F-Droid store or block ads using the great AdAway application (except for the mobile Firefox with the uBlock extension and Opera browser with ad blocking function). In fact, anti-virus protection secures the user's area with the same level of privileges as any other installed application. Thus, it comes to a strange situation in which malware getting root will have higher privileges than antivirus. This problem was partially solved by introducing the role of device administrators (although this is not the same as "root"). The installed application then gets access to the privileged permissions, which allows:

  • Control the change in the device lockout method.
  • Block the multimedia functions of your smartphone, e.g. the camera, voice recorder.
  • Block NFC, Wi-Fi, Bluetooth, calls and SMS.
  • Block the function of restoring factory settings.
  • Remotely wipe data.
  • Install or delete applications.
  • Forcing the use of e.g. GPS.

Malicious applications often try to get root privileges to make it difficult to detect and delete. Of course, mobile anti-viruses are not in a losing position because they constantly scan websites, files on the SD card, SMS messages, downloaded files and applications from the official and unofficial repository. However, it is very difficult to uninstall a malicious application that somehow has obtained root privileges or a device administrator role. If this happens, usually you should enable the debug mode in the advanced settings of development tools, pair the device from the PC and use the console to remove the threat or simply to system, or install a virus-free clean image of the Android system. Rooting a smartphone is not entirely obvious - it can cause a lot of problems for non-technical users, including the loss of the manufacturer's warranty.

The main difference between the "Find my device" functionality introduced by Google and similar programs to locate the location of a smartphone is the ability to delete data from an Android phone or tablet, or a Wear watch. However, this stick has two ends - privacy is a factor that can collect negative comments.

Putting Google's ideas into practice is a step in the right direction, however, security problems are still unachievable at this level of Android technology. The company from Mountain View has proven more than once that it can not deal with the distribution of malware by updating malicious applications in the store . It also can not deal with preinstalled with malware on new devices . In addition, the developers of Android and iOS are increasingly closing their environment to third parties, and this does not make work easier for software suppliers and security services. Is it wrong? No, but without a clear plan for the future, it's difficult to plan your business for several years ahead. Manufacturers, in order not to be far behind, have to look for other sales areas of their value-added services. The sooner they do, the better.

Three factors of preventive protection of IT areas with the company Quick Heal

1. Access control

If a "foreign" device is logged into the company network, we can assume that the network is not secure enough. An unknown device should not have access to all company areas. It does not matter if it is a laptop, private or business smartphone. Securing data against recognition, burglary and theft must be a priority for many entrepreneurs. Additional protection of access to the corporate network can be obtained by implementing the popular RADIUS protocol (supported by most popular routers), which will authorize the device and authenticates the user on the network. If we add the MDM solution (Mobile Device Management), which will enforce the access policies of mobile devices in wireless networks and access to resources on servers and cloud services, we will get a solid foundation for secure configuration of the company policy. The Mobile Device Management product separates the private and business zone by managing the zone with company applications for users of mobile systems and, if necessary, blocks the basic functions of the phone. The sooner and better we secure the IT area, the less time and resources we devote to analyzing the digital intrusion.

At Quail Heal, the Quick Heal Seqrite Mobile Device Management was adhering to international guidelines. Certificates ISO 9001, ISO 20000 and ISO 27001 confirm the modern standards of managing IT services (for which the company must give words of appreciation) - and what is connected with it - guarantee a high level of quality of services.

2. Application monitoring

In order to increase protection against a potentially malicious application (yes, Google Play contains a lot of malicious programs, in addition it can not detect them) Quick Heal Seqrite Mobile Device Management can block attempts to install applications from Google Play, iTunes, App Store , Windows Phone Store or from APK files. Administrators can refuse to install programs from predefined categories (eg games, instant messengers, social media), but this change can be made the other way - the Quick Heal Seqrite MDM agent will force installation of recommended company applications that will be downloaded and installed from official repositories (or from an APK file) with one click of an employee.

Quick Heal Seqrite Mobile Device Management allows you to create a safe work environment without any problems. We have a situation in which using only recommended applications will effectively discourage users from circumventing restrictions. After all, the business phone is owned by the company, not the employee, and the company sets the rules. Allowing privacy on a work phone is a privilege, not an obligation. Even after business hours. Selected applications in a cloud console can be managed, installed or blocked in a very simple way. Compatibility of the installed programs and system settings with the company's policy guarantee a safe, almost unbreakable environment.

3. Protection

The Quick Heal Seqrite Mobile Device Management solution is a product that supports security in a wide range. It allows significant control over protected company resources and installed applications, but above all protects the area of ​​mobile systems against malware supply chains.

Installed lightweight agent on the end device, having multiple awarded in independent tests engine antivirus, verifies the security of applications that could try to gain elevated privileges and seriously infect the operating system. Several protective layers, including a website scanner that distributes malware and phishing, will block attempts to display fake installers. Should this be necessary, the administrator can add a web address or IP address to the exceptions and thus permanently block or unblock the online resource on all mobile devices.

Multi-step attacks

By controlling the installed applications, eg using the proprietary Quick Heal Seqrite launcher or managing installed applications remotely (and adding those undesirable to the blacklist), we limit the risk of using the exploit, not only software, but also hardware. When at the end of 2016, researchers from VUSec Labs, the University of California and the University of Technology in Graz discovered a safety gap in smartphones working under the control of the Android operating system, the world learned that there is a way that allows you to get root privileges without interacting with the user.

Drammer is the first Android root exploit that relies on no software vulnerability and is an instance of the Flip Feng Shui exploitation technique.

Drammer was the first Android exploit that gave the highest permissions without exploiting any vulnerability in the system or in installed applications. By manipulating the data in memory and changing some of the bit sequences from 0 to 1 and vice versa, you could get root on some devices. As a result, remotely installing malware is a matter of a few commands. Most importantly, there is no way to defend against such attacks on vulnerable DRAMs - in theory the researchers gained access to the device by connecting it with a PC, but in practice you can arm the drive-by download attack into an exploit and install malware (although this will require interaction with user).

For companies and individual users, drive-by download attacks are a real nightmare. It is difficult to detect them, and in addition, the infection of the operating system usually takes place without interaction with the person sitting in front of the monitor. In the case of Android, the authors of the malware used the bug in the Google Chrome mobile browser. Normally, when downloading a file, the user must allow the downloading of data. However, the APK file can be split into 1024-byte pieces that are passed to the write function via the Blob () class, so without the user's knowledge the application will write on the device piece-by-piece. After downloading, the file will be reconstructed into a malicious application. The weakest link in this trick is interaction with the user - without installing the program, the Trojan will simply remain on the smartphone in the form of a harmless file. However, this does not change the fact that the technique of downloading the resource from a remote server to a mobile device - and without interaction with the user - has been used in real attacks.

Quick Heal Seqrite MDM for problems with mobile devices

Android security issues remain unresolved by Google. Theorizing, since the user has to download and install the malicious application himself (or with the help of social engineering), in practice no serious infection should ever happen. The latest information about the set vulnerability KRACK on WPA2 protocol and vulnerable to remote attacks of wireless Bluetooth communication prove that every smartphone can be a potential carrier of an infection, actively looking for another, vulnerable device.

In working environments particularly sensitive due to processed information (eg banks or hospitals), the solution of the Mobile Device Management class gives its manager an advantage over cyberthreatures resulting from internal as well as external factors. Easy access to the console based on cloud technology allows the administrator to flexibly configure policies that provide a solid foundation for the security of the organization. If the devices we authorize are correctly implemented using the company's infrastructure, we get the total visibility of all mobile smartphones connected to the company's network. As a result, we will get full control - including a comprehensive inspection of all applications that, if managed by the administrator, will maintain policy compliance and increase employee productivity. In addition, functions such as network filtering, anti-theft protection and location tracking will ensure the security of the devices. There is nothing worse for an administrator than a ghost device that does not know who it belongs to, where it came from and what resources it has access to. In case of any problems, customers can count on technical support provided by the Polish branch of engineers and directly by the manufacturer (by phone, email or chat) 24 hours a day and 7 days a week.

In addition to controlling and managing functions, the Quick Heal Seqrite Mobile Device Management solution, as befits a product with ISO 9001, ISO 20000 and ISO 27001 certifications, can generate comprehensive and useful reports on all protected devices. It is possible, for example, to generate a report for devices that do not meet the current policy settings, because, for example, they do not have installed recommended applications or system settings are incompatible with those introduced by the administrator. It is also possible to specify information about calls and SMS messages, installed applications, or make an inventory broken down into devices, users and IMEI numbers of each smartphone and tablet.

What is the future of mobile anti-viruses?

Users' awareness of security slowly, but systematically hammers the last nails to the lid of the mobile anti-virus software coffin. But there is nothing wrong with it that would not work out. Other areas are waiting for development, such as: active monitoring of applications, controlling the functions of a smartphone, enforcing access to company resources, or separating a private and business zone. And precisely on the grounds of prevention (filtered & amp; deny) company Quick Heal finds its niche by offering the security of mobile devices.

Is it worth to implement the MDM solution, just preventively, to save yourself gray hair, the costs of reproducing lost data and not to mention the consequences resulting from the GDPR? As usual, the decision is conditioned by an individual approach to security.
