1.1 Information Security of a Modern State

In addition, the development of protective technologies affects the activity of
hackers. And this is understandable, since protective measures will not be developed
even for the most sought-after technology, until it is attacked by hackers. A striking
example of this is the Wireless LAN technology, which had no serious protection until
recently. Specialized protection tools and mechanisms began to appear as soon as the
actions of the attackers demonstrated the entire vulnerability of wireless networks,
including vulnerability scanners (for instance, Wireless Scanner), attack detection
systems (for instance, AirDefense or Isomar IDS), etc.
Nowadays the term “communication field” is often used in marketing to refer to
the social circle of an individual/a target group of people.
Therefore, different companies use different protective technologies depending on
such ways of generalization. For instance, VPN technology (Virtual Private Network)
is never used to access the Internet but it finds wide application when a client interacts
with remote branches.
The choice of a competitive information security technology is largely influenced
by the size of a group of computers, which is now commonly known as a network.
The scale of the network is decisive—both because of the lack of funds to acquire
the necessary information protection technologies, and because there is no need for
the latter (Fig. 1.2). For example, as a rule, there is no need for sophisticated systems
to control the leakage of confidential information for a single computer connected
to the Internet, while such systems are vital for a medium-sized network.
In small information networks, the problem of centralized management of information security tools is not so pressing, while such tools are indispensable in networks
of large enterprises. Therefore, large networks generally use correlation systems,
