VERNA offers services for building and maintaining a comprehensive enterprise information security system of enterprises, which reduces the risks of loss or leakage of information, reduces the cost of implementing and operating various security systems, allows to prevent and eliminate the consequences of a virus attack, restore the operability of IT infrastructure.
The implementation of the anti-virus protection system of information networks provides
• control of all possible channels of penetration of viruses - e-mail, allowed to interact with the Internet network protocols (HTTP, FTP), external media, data file servers;
• protection against various types of threats - viruses, network and mail “worms”, “Trojans”, unwanted programs;
• constant antivirus monitoring and periodic antivirus scanning of all servers and workstations;
• automatic notification in case of “infection”, “treatment” of viruses;
• protection of mobile devices and more.
When choosing a particular product, one should be guided by criteria such as the performance of the systems on which the antivirus solution is supposed to be used, the results of own testing, the ratings of independent research companies, ease of administration, the presence of a centralized management system.
Functional scheme of a gateway solution operating in monitoring mode
The main part of any antivirus is the so-called Anti-Virus Engine - an antivirus engine that is responsible directly for checking objects and detecting malicious code in them. For different manufacturers, the algorithm of work is built in its own way, however, in general, the principle of operation is the same. So, all engines have antivirus databases that store information about known viruses discovered by manufacturers' research laboratories. Any modern antivirus will try to “cure” the software from malicious code, but if this fails, the suspicious file will be quarantined or deleted. If a virus is suspected, the antivirus software sends the data for verification to the specialists of the manufacturer, who then add information about the existing malicious code to their antivirus databases. It is on the antivirus engine, on how it is designed, what methods it uses to detect viruses, that depends on the effectiveness of detecting malicious code and, as a consequence, the level of protection that the antivirus provides. Therefore, when testing various antivirus products, it is this module that should be given the greatest attention, check its quality and evaluate its impact on the performance of the hardware platform on which it works.
Due to improper actions of employees, as well as due to deliberate theft of corporate data, companies suffer losses that far exceed the costs of ensuring information security. To ensure the protection of confidential information and intellectual property from intentional or unintentional leakage, it is proposed to use products belonging to the DLP class - Data Loss Prevention - Data Loss Prevention.
DLP solutions prevent unauthorized operations with confidential information - copying, changing, etc. and its movement - sending, transferring outside the organization, storage in alternative directories, etc. through control. Modern DLP systems have many characteristics and functions that must be considered when choosing a solution to protect against leaks of confidential information. One of the key parameters of any DLP system is the network architecture used.
According to this parameter, DLP solutions are divided into two groups: gateway and host. IN gateway DLP solutionsa server is used to which all outgoing network traffic of the corporate network is directed. The gateway processes this traffic in order to detect possible leaks of confidential data. Hosted DLP Solutions are based on the use of software agents that are installed on workstations, servers, etc.
The best option is to share the two types of DLP, but each task must be considered separately. Often, customers choose a hosted DLP as the first solution to prevent leakage of confidential information, and the gateway is added to the circuit if necessary.
VERNA's information I/O control system allows you to prevent accidental and unforeseen cases of unauthorized transfer of corporate data to external media and regulate the further use of data I/O devices in accordance with the organization's information security standards.
There is a whole class of device control systems that perform the following functions:
• Exercise control over copying data to different media and through different ports.
• Allow or prohibit the use of certain devices and the copying of certain data to authorized devices and restrict the copying of data by users from certain locations and applications.
• Centralized assignment, deployment, administration and updating of policies and safeguards across the enterprise through a centralized management system that allows you to configure device and data usage policies for each user, group, or department.
• Obtaining detailed information about devices, timestamps, data, etc. in order to conduct an audit quickly and correctly.
Device control systems operate on a single principle - an agent that is installed on users' workstations monitors physical ports according to policies that are configured by system administrators. Agents are often deployed to user PCs via AD Group Policies or through the server part of the solution, which allows agents to be centrally managed from a single console.
Network perimeter security solutions can be divided into groups such as internetwork screens, intrusion prevention systems, selective network access control tools, behavior analysis tools and security threat detection mechanisms, virtual private networks.
Today, there are many means of network protection, for example, universal UTM devices, which combine a whole range of information security functions in one software and hardware platform. Such solutions can significantly reduce the costs not only for the purchase of equipment, but also for the resources of managing such a solution. The most common mechanism for protecting the perimeter of the network was and remains the internetwork screens (FIREWALLS). The main task of such systems is to protect access to information resources from the outside:
•Protection against network attacks (IPS, IDS).
• Build secure communication channels, both between networks and for access by mobile users (IPsec VPN, SSL VPN).
•Network access control and authentication.
• Control access of internal users to external resources.
• Division of the common network into zones.
• Traffic analysis for security threats.
• Monitoring the state of communication channels.
Kompatibiliteit
Operating systems from the Open Source family can cause many problems with hardware compatibility. At the same time, when the equipment can be supported by the system as a whole, a particular implementation of it may not work properly or as expected, or it may not cooperate with a particular combination of equipment. In commercial solutions, such problems do not arise the day before, since the software part is developed in tight connection with the hardware.
Total Cost of Ownership (TCO)
When considering purchasing, implementing, and owning a system, an important part is the total cost of ownership. In the case of open source solutions, the purchase cost will be equal to the cost of only the hardware part, which is much cheaper than commercial solutions where various licenses are additionally purchased.
Warranty and Support
In the matter of modifying the software part, updates, resolving controversial issues, the unconditional and unconditional advantage remains for the commercial decision, since the manufacturer and the integrator are responsible to the customer for the purchased and implemented solution. The quality of the work performed is controlled by acts and contractual obligations.

Load balancing technologies between computing resources have become relevant with the proliferation of Internet resources and social networks, as well as applications and distributed data between remote sites. Currently, a large number of people daily use Internet services, access to which load balancers are involved. At the same time, most users do not even suspect about their existence. At the same time, if they did not exist, the provision of services would be very problematic.
The tasks of load balancers include ensuring the scalability of computing complexes, resistance to service failures, managing server connections, and protecting server equipment from attacks by intruders.
Load balancers allow you to distribute the current traffic of applications between servers, as well as control and change its characteristics according to the specified rules.
