In the age of information technology, when the Internet has become an integral part of modern life, the issue of personal safety online is becoming increasingly important.

Most users are not concerned about their online security, because they just don’t know how to do it properly and don’t think about the possible consequences, starting from scammers who steal their logins and passwords from pages in social networks, and ending with the bankruptcy of the company where they work.

Unfortunately, work on the Internet is not always safe. Today, most companies begin to think about security systems only after something happens to their information resources.

We will tell you why you should think about the security of your online business in advance.

First of all, always remember that your personal information on the Internet should be kept to a minimum.

Nowadays it is difficult, because registration on various services requires, for example, sms-confirmation, especially if you are engaged in Internet business. We recommend using the reliable service

A one-time phone number will allow you to easily register in the services or messengers you need.

One can imagine the consequences of destroying the client base or accounting information for the reporting period, and competitors reading business correspondence by e-mail or monitoring the contents of any station from a remote computer is not conducive to business prosperity either, because according to statistics only 7-10% of attacks are detected at all.

In other words, there is the potential for hackers to covertly monitor corporate information sharing.

These problems are especially acute for Internet portals, mostly B2B portals, because information passes through them, the loss of which is costly.

1. Firewalls

All security products are classified in a certification system. The use of such systems, when properly configured, can significantly reduce the risk of intrusion into an organization’s information network.

Firewalls can be implemented either as a hardware device or as software installed on a computer, and the common opinion that the former are much more reliable than the latter is not always true; as for cost, hardware products are almost always much more expensive than their software counterparts.

A firewall’s task usually comes down to filtering IP traffic – in other words, it analyzes incoming and outgoing IP packets and only allows those that meet the specified requirements to pass.

Unfortunately, with this type of protection internal attacks by disloyal employees of the organization remain unnoticed, although statistics show that the proportion of such attacks in the total number of information attacks to date exceeds 70%.

It is for this reason that personal firewalls, installed directly on the workstation and turning it into a protected object, have recently begun to appear.

Such a screen not only protects the computer from unauthorized access, but also establishes a policy of access to external resources for each user.

For example, the administrator can create a “white list” of web resources that a user is permitted to work with and deny access to the rest of the open resources of the network.

Screens are installed both on servers and workstations. The owner of the computer using them can access any open Internet resource in accordance with the specified security policy, but any attempt to access it from the outside world will be blocked by the system, informing the owner about it and fixing the IP address of the person who made the attempt.

2. Cryptographic Protection Products

Another category includes products for secure exchange, which are by far the most secure in terms of security. As a rule, they are based on cryptography – the science that studies methods of transforming open information into closed information.

Encryption protects not only data stored on a hard drive, but also information transmitted over networks, including the Internet. Both the e-mails and the information exchanged between the subscribers online can be protected.

Systems that allow any data to be transmitted securely over the Internet are called virtual private networks (VPNs).

VPNs provide a completely private exchange of information over an open network. This is why they are called private. Information in such systems is usually encrypted using special software keys.

From a security point of view, the main issue here is the structure of the key: how and where it is formed, where it is stored, how it is transferred, who has access to it.

Today there are only two types of encryption algorithms: symmetric (classical) and asymmetric. Each has advantages and disadvantages.

Symmetric algorithms use the same key for encryption and decryption, and it can be opened only by brute force, which is practically impossible if the key length is sufficient.

However, this method has one disadvantage: before sending each other confidential information, two users must exchange a shared key, which naturally causes great inconvenience.

In addition, such keys are usually issued by some formation center, which means that they are known only to that center. To overcome this drawback, algorithms with asymmetric keys were created.

The basic idea of asymmetric key cryptography is to use a pair of keys. The first, a public asymmetric key, is available to anyone who is going to send messages to the owner of the key.

The second, a secret asymmetric key known only to its owner, is used to decrypt messages encrypted with its associated public key. Thus, the secret part of the key is formed and stored directly with the subscriber and is not available to anyone else.

3. Security services

The next step in Internet security can be comprehensive services.

Constant improvements in security technology on the one hand and attacks on the other force companies to keep security specialists, buy more and more new products, and often obtain licenses from the relevant authorities to use certain security products.

All these problems can be avoided if this work is done by a team of professionals who have knowledge, experience, the latest security technologies and the necessary licenses. This is what the IIT project was opened for.

Each corporate computer should be equipped with a professional security system, all traffic between computers should be protected, and this should be done without waiting for unpleasant events.

Only with this comprehensive approach will the Internet be safe for the businesses that work on it.
