TOP free antiviruses of 2020

In the age of digital technology, hacking of devices remotely via the Internet has become more frequent. They are called Internet scammers; you can protect your device using a powerful utility called antivirus.

We have already identified for you the most powerful and popular applications on Android, all you have to do is choose the best one for your device.

Introduction

Sophos Endpoint Security and Control 8 consists of the following components:

1. Sophos Anti-Virus. Designed to protect corporate networks from malware. In addition to signature analysis, the antivirus also relies on built-in proactive protection, which allows you to detect unknown threats. This exciting opportunity exists thanks to two technologies - Sophos Behavioral Genotype and Sophos HIPS.
2. Sophos Application Control. A special technology that can be used to ban the use of applications that are legal, but often undesirable in a corporate environment: instant messaging programs, games, file-sharing clients, etc.
3. Sophos Enterprise Console. Provides the administrator with the ability to deploy all components of the solution on computers on the network and subsequently manage them.
4. Sophos Client Firewall. A personal firewall designed to control the network activity of client computers.
5. Sophos NAC agent. The agent is designed to provide a unified access policy to network resources and is based on Network Access Control technology, which supports Cisco Network Admission Control, Microsoft NAP and analogs. To manage it, you will need to additionally install the Sophos NAC management server.

By default, only antivirus is deployed to the entire network, but you can additionally install:

Testing antivirus protection

For testing, antiviruses are given samples of different types of malicious code to see how they react. Typically, an antivirus is able to remove most of these samples and detect the rest when you try to run them. The score for blocking malicious applications ranges from 0 to 10.

Because the same samples are used month after month, this test does not show the antivirus's ability to block new threats. In a separate test, malicious applications are downloaded from 100 new suspicious addresses from the London testing laboratory MRG-Effitas. Usually these addresses are only a couple of days old. It analyzes whether the antivirus can block access to this address, erase malicious code during downloading, or whether it does not notice anything. In the last similar test, Sophos Home Free, McAfee and Vipre scored 100%.

Key Technologies

• Genotype technology is proactive protection against so-called “zero day” threats. Provides recognition of viruses or entire families of malware using fuzzy signatures.
• Behavioral Genotype Protection is a protection module that can block malicious programs before they are launched.
• Built-in host intrusion-prevention technologies is a module for pre-executing a suspicious file or process. It allows you to detect buffer overflow attacks.
• Decision Caching speeds up your antivirus program by caching and scanning only new and changed files.
• Sophos NAC is a security policy management system, thanks to which client (especially mobile) computers are allowed to access network resources only if they fully comply with the established security policy.
• The drag&drop control method allows you to quickly perform routine operations, which makes everyday work with the management console easier.

Installation

To install the management console, you need a 2 GHz processor, 512 MB of RAM and at least 2 GB of hard disk space (the product itself takes up about 100 MB, the rest of the space is needed for the database). An Internet connection is also a mandatory requirement. After downloading the distribution and running the network installer, Sophos EM Library, a system for managing anti-virus updates and distributions of protection components, will be installed first on the server.

Figure 4.1. Sophos EM Library - a system for managing antivirus updates and distributions of protection components

The EM Library system allows you to manage updates for all Sophos antivirus products on all supported platforms. You can have several EM Library servers within one network, dividing them into master and slave servers. Typically, one such server is placed in a demilitarized zone, and another one can be placed, for example, in a “treatment zone” (remediation zone), used to update the protection status of computers that have not been authorized in Sophos NAC and are not allowed into the general network.

In addition, the ability to create a hierarchy of EM Library servers can be very useful if the enterprise network consists of several segments located geographically. In this case, each segment can have its own update server, which significantly reduces traffic.

After the EM Library system, the Sophos management server and the Sophos Enterprise Console management console are installed.

After installing these components, a reboot is not required (exception: Windows 2000).

To make it easier to further deploy and manage the solution, the console allows for the creation of computer groups. Groups are required, first of all, in order to simultaneously install and configure an antivirus solution on computers that require the same security settings. For example, computers located in the accounting department have one set of parameters, while the laptops of managers, who are often outside the corporate network and can bring a new virus from outside, have another.

Another useful tool allows you to find matching machines on your local network by IP address range or using Active Directory. Sophos can also synchronize computer groups defined in the console and groups created in Active Directory, thereby relieving the security administrator of doing this work manually.

The next step is to ensure that the found computers are protected. A special wizard, Protect computers wizard, helps you cope with this task.

The antivirus is installed on the client machine in a matter of minutes. Along with the antivirus, the Application Control application management system will be installed. Also, if necessary, you can install Sophos Firewall and Sophos NAC Agent separately.

After deployment, the antivirus can be updated either by the user from the client computer or by the administrator through the management console.

Management Console

Using the policies provided in the console, the administrator can configure the schedule for issuing updates for each group of computers. Spreading this operation in time is usually used in large networks in order to avoid too much load on the update server and the network.

Testing

User Interface and Settings

Management Console

An automated management console makes it possible to deploy, update, and subsequently monitor the operation of antivirus, firewall and NAC agents. One such console can control tens of thousands of machines. It allows the administrator to assess the degree of risk and monitor the security status of computers on the network.

The entire network is in the administrator's field of view - thanks to this advantage, it is possible to protect machines from malicious and unwanted software in the shortest possible time. In addition, as we have already noted, it is possible to monitor programs that are legal but not desirable in an organization - these are instant messaging clients, media players, file-sharing clients, games, etc. Sophos points out the serious danger of using uncontrolled network applications on workstations, since the traffic they generate can cause the corporate network to become infected. In addition, control of such applications helps to avoid leakage of confidential information, for example, through ICQ.

To migrate from a previously installed security solution to Endpoint Security and Control, you have the option to automatically remove third-party applications during deployment by checking the appropriate box:

Searching for computers on a local network, a range of IP addresses, or in Active Directory is very easy:

Risk levels are displayed on the console dashboard. As soon as a virus, potentially dangerous or unknown application is detected, the administrator will immediately receive a visual notification of this incident through the management console display system.

Incoming alarms are collated and assigned one of three statuses - blue ("Everything is OK"), orange ("Warning") and red ("Critical Situation").

By clicking on the Smart Views area, the administrator can:

• Select an alternative view to focus only on machines whose protection is outdated or on machines where critical situations have been detected. This sorting allows you to instantly assess the situation in problem areas of the network.
• Change the thresholds for assigning each of the three statuses.

By default, information about detected viruses is displayed on the dashboard. A warning email may also be sent to the administrator. A pop-up window will appear on the client computer with the name of the virus and a link to the Sophos virus encyclopedia site, where the user can find detailed information about the threat.

After a virus attack, the administrator can use the console to centrally delete infected files, registry entries and running processes.

The Smart Views element provides a complete picture of the security status of all machines on the network. It is possible to switch viewing to problem areas of the network or computers that need updating.

Essentially, the console interface provides a list of computers, and the administrator can use various filters (for example, by selecting computer groups, using Smart Views or a dashboard) to narrow this list in accordance with the task that he currently wants to solve. For example, if an administrator needs to deploy Sophos client software on new computers, they can select the “Only managed, not protected computers” filter.

Sophos Active Policies configuration technology allows you to create sets of rules for each Sophos protection component (for example, setting up anti-virus protection, update system, Application Control, etc.), and then issue commands to use these rules in groups of computers using drag&drop. Thus, you can configure thousands of computers in the shortest possible time. In addition, Active Policies allows you to create special rules “in reserve”, that is, those rules that are not used normally, but can be activated if an information attack is detected, for example.

• If a user on a workstation has access to change the settings of protection components and has performed a reconfiguration, the administrator will receive a notification about this using the management console

The antivirus also provides protection using a built-in intrusion detection system (HIPS). The technology allows you to analyze running processes, prevent buffer overflows, and proactively detect malicious program code when it attempts to perform an illegal operation (for example, scan a hard drive to find email addresses and send what is found to the “master” of the virus, who collects a database for future spam distribution). The HIPS system in the Sophos solution is easy to set up.

The policy allows you to specify a wide range of options for scanning the entire network. By default, the following settings are applied:

• scanning all files for vulnerabilities and malicious code;
• prohibiting access to any malicious object;
• informing about a security issue using a pop-up window.

Instant messaging applications, voice communications, file-sharing clients and other similar legal programs can pose a threat to a company's information security. Sophos Anti-Virus can detect such applications along with malicious ones and report an attempt to use them to the administrator. By default, all these applications are allowed to be used. You can configure the list in the Application control menu of the management console.

Configuring NAC (network access policy management based on Cisco Network Admission Control, Microsoft NAP and other technologies) is carried out using NAC Manager, which is launched by double-clicking on the NAC policy item. NAC Manager provides additional reports, notifications, and policy editing options. It is divided into four areas:

• Manage – provides editing of management policies;
• Enforce – controls application access to the network based on patterns and allowing rules;
• Report – offers a set of reports to solve problems related to network access;
• Configure – provides control of the status of components necessary to manage the system, parameters and settings.

On the client machine, the user has access to scanning, various settings, and management of his own Quarantine Manager. The client-side interface is greatly simplified for the convenience of untrained employees.

Infected files that have been deleted are placed in Quarantine Manager. The component allows you to selectively block potentially dangerous and unwanted applications.
