Cisco Security Solutions
The Cisco security products also represented by Synergon provide a complete,
integrated solution to an enterprise's network security issues and requirements.
These products can be classified into the following three main solution groups:
- boundary protection firewall systems
- VPN virtual private network systems
- intrusion detection (IDS) systems
Today the use of the firewall, boundary protection systems is already a basic
requirement for a secure Internet connection of an enterprise or for the implementation
of its presence on the Internet. Moreover, the application of firewalls is expedient
not only for the development of the publicly accessible, so-called demilitarized
or internal boundary protection zones but also for the further segmentation of
the enterprise's network, that is the development of further boundary protection
zones, e.g. for the implementation of the B2B communication between the partner
Moving on a wide scale, Cisco’s firewall products meet the requirements from
the more simple small enterprise solution as well as the large enterprise, high
availability, so-called HA solutions.
The VPN virtual private network systems offer a secure and cost effective method
for the implementation of the so-called Intranet communication between the different
sites of the enterprise, the so-called Extranet communication between the partner
enterprises or the remote and mobile access, the so-called home-working and mobile-working.
It is generally used to increase the security of communication on the Internet
or wireless WLAN networks which are subject to a higher level of threat. VPN systems
apply the IPsec Internet security standards, which satisfy the requirements of
confidentiality, integrity and accountability – among other things – by means
of verifying the DES, 3DES or AES traffic encrypting and the origin of the package.
The detection of internal or external attacks against the information technology
systems, the initiation of countermeasures – preferably – in due time are of basic
importance to avoid or decrease damages – if it cannot be avoided any more. The
intrusion detection (IDS) systems is capable of recognizing the known intrusion
patterns and initiating possible countermeasures – e.g. the interruption of the
communication channel, the exclusion of the user – at several points of the information
technology system, at the critical network segments and the critical application
servers, as well as reporting the event towards the central management station.
NAC - Network Admission Control
The so-called Network Admission Control technology has become a more well-spread
protection mechanism. This solution is devoted to prevent hosts which are not
in conformity with the enterprise’s expectations from security aspects from connecting
into the system. The typical objective is the exclusion of machines which have
security inadequacies, such as an out-of-date virus definition, lack of Windows
patches or negligence of using a firewall from our network. Should the connection
of these machines be enabled the security of the other, properly operating machines
would be threatened. Cisco is the most popular among the NAC solutions listed
on the market, and it has the most significant history in comparison to its rivals.
