Overview of VPN protocols.
VPNs (Virtual Private Networks) are often viewed from the perspective of security with the goal of providing authentication and confidentiality.
However, the primary purpose of VPNs is to connect 2 topologically separated private networks over a public network (typically the Internet).
VPNs basically hook a network logically into another network so that both appear as one private local network.
Security is a possible add-on to VPNs. In many cases it makes perfectly sense to secure the VPNs communication over the unsecure public network.
VPN protocols typically employ a tunnel where data packets of the local network are encapsulated in an outer protocol for transmission over the public network.
The most important VPN protocols are IPSec, PPTP and L2TP. In recent years SSL/TLS based VPNs such as OpenVPN have gained widespread adoption.
A computer network is defined as the interconnection of two or more computers. It is done to enable the computers to communicate and share available resources.

A virtual private network gives secure access to LAN resources over a shared network infrastructure such as the internet. It can be conceptualized as creating a tunnel from one location to another, with Encrypted data traveling through the tunnel before being decrypted at its destination.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

What is VPN
Types of VPN’s
How does it work?
Protocols
Security: Firewalls
VPN Devices
Advantages

Features
Future
Conclusion
3. What is VPN
Virtual Private Network is a
type of private network that
uses public telecommunication,
such as the Internet, instead of
leased lines to communicate.
Became popular as more
employees worked in remote
locations.
Terminologies to understand
how VPNs work.
5. Remote-Access VPN
A remote access VPN is for home or travelling
users who need to access their central LAN from a
remote location.
They dial their ISP and connect over the internet
to the LAN.
This is made possible by installing a client software
program on the remote user’s laptop or PC that
deals with the encryption and decryption of the
VPN traffic between itself and the VPN gateway on
the central LAN.
6. Site-to-Site VPN
Intranet-based - If a company has one or more
remote locations that they wish to join in a single
private network, they can create an intranet VPN
to connect LAN to LAN.
Extranet-based - When a company has a close
relationship with another company (for example, a
partner, supplier or customer), they can build an
extranet VPN that connects LAN to LAN, and that
allows all of the various companies to work in a
shared environment.
9. Protocols used in VPN
PPTP - Point-to-point tunneling protocol
L2Tp – Layers to Tunneling Protocol
IPSec - Internet protocol security
SSL – is not used as much as the ones above.
Encryption
10. VPN Security: Firewall
A well-designed VPN uses several methods for keeping
your connection and data secure:
Firewalls
Encryption
IPSec
AAA Server
You can set firewalls to restrict the number of open
ports, what type of packets are passed through and
which protocols are allowed through.
12. VPN Advantages
Multiple telephone lines and banks of modems at the
central site are not required.
A reduction in the overall telecommunication
infrastructure – as the ISP provides the bulk of the
network.
Reduced cost of management, maintenance of
equipment and technical support.
Simplifies network topology by eliminating modem
pools and a private network infrastructure.
VPN functionality is already present in some IT
equipment.
13. VPN Disadvantage
If the ISP or Internet connection is down, so is the
VPN.
The central site must have a permanent internet
connection so that remote clients and other sites can
connect at anytime.
VPNs may provide each user with less bandwidth than
a dedicated line solution.
Existing firewalls, proxies, routers and hubs may not
support VPN transmissions.
14. VPN Features
Security – tunneling support between sites with at
least 128bit encryption of the data.
Scalability – extra users and bandwidth can be added
easily to adapt to new requirements.
Services – quality of service features, including
bandwidth, management and traffic shaping, are
important to avoid congestion.
Management – reports on user activity, management
of user policies and monitoring of the VPN as a whole.
15. Future of VPN
VPN popularity
Companies choosing VPN
Cost efficient?
New way of communicating?
17. Conclusion
As we have gone through all possible details we
conclude that VPN is the best option for the corporate
networking.
As many companies need to have access to Internet
and hence security is also the main concern.
VPN provides best possible combination of security
and private network capabilities with adequate cost –
saving to the companies who are presently working
with leased lines.
