Protecting information from risks and leaks is an important service offered by VERNA. We specialize in creating and maintaining a comprehensive security system that helps businesses reduce information security costs and prevent data loss. Our services also allow you to avoid the consequences of virus attacks and restore the work of the IT infrastructure.
One of our main areas is the implementation of antivirus protection systems for servers and workstations. These systems provide:
• Control over all possible routes of virus penetration, such as email, network protocols (HTTP, FTP), external data carriers and file servers.
• Protection against various types of threats, such as network and mail viruses and unwanted programs.
• Continuous monitoring and periodic scanning of all servers and workstations for virus detection.
• Automatic information about infection and the process of treatment from viruses.
• Mobile device protection and other features.
When choosing a suitable antivirus solution, several criteria should be taken into account, such as the performance of the systems to be used, the results of our own testing, the ratings of independent research companies, ease of management and the availability of a centralized management system.
The functional scheme of the gateway solution, operating in monitoring mode, includes key components that ensure the operation of antivirus protection. One of the most important elements of this scheme is the antivirus engine, also known as the Anti-Virus Engine. This engine is responsible for checking objects and detecting malicious code in them. Different manufacturers may have their own algorithms, but the general principle of operation is similar.
Antivirus engines include antivirus databases that contain information about known viruses discovered by manufacturers' research laboratories. When you try to “cure” an infected object, the antivirus will try to remove the malicious code, and if this is not possible, the object will be quarantined or deleted.
If the file is suspected of having a virus, the antivirus software sends the data for verification to the manufacturer's experts. These experts analyze suspicious code and, if malicious activity is detected, add information about it to antivirus databases. The effectiveness of malware detection and, accordingly, the level of protection provided by the antivirus depend on the development of the antivirus engine and the virus detection methods used.
When testing various antivirus products, special attention should be paid to the antivirus engine. This includes checking the quality of its work and assessing the impact on the performance of the hardware platform.
Include various solutions that aim to ensure the security of the network perimeter. These solutions can be divided into several groups, such as firewalls, intrusion prevention systems, network access controls, behavior analysis and security threat detection tools, and virtual private networks.
Today, there are many different means to ensure network protection. For example, universal UTM devices that combine a set of information security functions on one software and hardware platform. The use of such solutions allows you to significantly reduce the costs not only for the purchase of equipment, but also for managing these solutions. One of the most common mechanisms to protect the perimeter of the network is the use of internetwork screens (firewalls). The main task of these systems is to ensure the protection of access to information resources of external users:
• Protection against network attacks (intrusion prevention systems and intrusion detection systems).
• Build secure communication channels between networks and to ensure access for 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 to identify potential security threats.
• Monitoring the state of communication channels.
Kompatibiliteit
The use of operating systems from the Open Source family can lead to various hardware compatibility problems. Even if the equipment as a whole is supported by the system, its specific implementation may not work properly or as expected, or 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 taking into account specific hardware.
Total Cost of Ownership (TCO)
When considering issues regarding the acquisition, implementation and ownership of a system, an important component is the total cost of ownership. In the case of using open source solutions, the purchase cost is limited only to the cost of the hardware, which is much cheaper than commercial solutions, where it is additionally necessary to purchase various licenses.
Warranty and Support
In the matter of modifying the software part, receiving updates and resolving controversial issues, commercial solutions have unconditional advantages, since the manufacturer and integrator are responsible to the customer for the purchased and implemented solution. The quality of the work performed is controlled by means of acts and contractual obligations.

With the proliferation of Internet resources, social networks and applications, load balancing technologies have become very important. VERNA offers services for the implementation of content analysis and filtering systems when accessing Internet resources. Our specialists will develop a technical solution to create a system that integrates with the customer's existing protective equipment. As part of the solution, a package of design and operational documentation is provided.
The tasks of load balancing are to ensure the scalability of computing complexes, resistance to service failures, manage server connections, and protect server equipment from attacks by intruders.
Load balancers allow you to distribute the current traffic of applications between servers and control its characteristics according to established rules. They are invisible to most users, but play an important role in ensuring the availability and efficiency of Internet services. Without them, the provision of services would be a problematic task.
Avoid cases of unauthorized transfer of corporate data to external media and regulate the use of input/output devices in accordance with information security standards.
There is a whole set of device control systems that perform the following tasks:
• 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 on authorized devices, as well as limiting the copying of data by users from certain locations and applications.
• Centralized assignment, deployment, administration and updating of policies and safeguards in 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 and other parameters for a quick and correct audit.
Device control systems operate on the basis of agents that are installed on user workstations and monitor physical ports according to policies set by administrators. Often agents are distributed to users' PCs through Active Directory group policies or through the server part of the solution, which allows you to centrally manage agents from a single console.
are necessary to prevent damage that may result from employee misconduct or intentional theft of corporate data. To effectively protect confidential information and intellectual property from leakage, it is proposed to use products that belong to the category DLP (Data Loss Prevention - Data Loss Prevention).
DLP solutions prevent unauthorized transactions with confidential information, such as copying, modifying, and other actions, as well as its movement, such as sending or transferring it outside the organization, storing it elsewhere. Modern DLP systems have many features and characteristics that must be considered when choosing a solution to protect against leakage of confidential information. One of the key factors is the network architecture used in the DLP system.
According to this parameter, DLP solutions are divided into two categories: gateway and host. Gateway DLP solutions use a server that processes all outgoing network traffic of the corporate network in order to detect possible leaks of confidential data. Hosted DLP solutions, on the other hand, are based on agent software that is installed on workstations, servers, etc.
The optimal approach is to use a combination of both types of DLP, but each task must be considered separately. Often, customers first choose the hosted DLP as the first solution to prevent leakage of confidential information, and the gateway is added to the system if necessary.
Implementation of host DLP allows you to provide control over an active workstation, server, or other devices. This allows you to detect and block attempts of unauthorized access to confidential data, monitor transactions with them and track their movements. A hosted DLP can monitor files, user activity, and enforce security policies at the device level.
On the other hand, gateway DLP provides centralized protection of the network as a whole. It intercepts the traffic that passes through the network entry and exit points and analyzes it in order to detect and block possible leaks of confidential information. Gateway DLP allows you to apply unified security policies for the entire network, control data transmission, filter and block unwanted content or activity.
The smart approach is to carefully evaluate your organization's needs, select the appropriate functionality, and establish the optimal combination of host and gateway DLP to achieve the highest level of protection against leakage of confidential information.
