VPNs encrypt traffic between remote locations to allow secure access to an organization's internal network. There are two main types of VPNs: user VPNs which allow individual employees to access the network remotely, and site VPNs which connect entire office locations. User VPNs require authentication of individual users while site VPNs authenticate each connected location.
A VPN is an extension of an enterprise's private intranet, across a public network (Ex:Internet), through the creation of a secure, authenticated and encrypted "tunnel"
Virtual private network feature and benefitsAnthony Daniel
Cyberoam VPN offers the option of IPSec VPN, SSL VPN, LT2P, PPTP on the UTM appliances, providing secure remote access to organizations. It replaces most other best-of-breed firewall-VPN appliances to offer cost-effective security to organizations.
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.

Developing a VPN Policy and EnforcingVPN Best PracticesEnt.docxlynettearnold46882
Developing a VPN Policy and Enforcing
VPN Best Practices
Enterprise-Class Security Considerations
Develop virtual private network (VPN) usage and security policies to the exact scale and scope of the network.
Ensure that only approved individuals and authorized third-parties access and use the VPN service by performing the following:
· Establish strong authentication mechanisms. For example, token devices, private keys, or passphrases.
· Establish VPN usage restrictions, like who may use it and how it may be used.
· Force VPN traffic through the VPN tunnel and drop all other traffic.
· Enforce strong password selections and idle user logon timeouts.
· Enforce strict VPN client usage and maintain updates on mandatory security software (that is, antivirus.)
Remember to notify remote users that they are subject to the company’s network rules and regulations. Develop a roadmap to check, recheck, configure, update, and service VPN components as per the schedule. VPN policies cover everything from security practices to maintenance routines.
Define Users, Groups, and Access Rights
Ask important questions about who can use the VPN, how they can use it, and what to track and record when they use it. Your VPN policy should generally address every foreseeable usage scenario, user behavior, and unauthorized activity. Start with highpoints and drill down into the specifics. Define acceptable behavior and develop procedures and processes for enforcing compliance and handling violations. Some considerations are:
· The types of users and groups who may remotely access the network:
· Employees who work from home and need to access the company intranet.
· Server administrators who often need to update and make changes on their server machines remotely.
· Branch office workers who need a secure connection to the main office intranet.
· Off-site contractors working on a project with company personnel.
· Servers, services, and systems that remote workers should be able to access:
· VPN servers must be authorized by the network administrator.
· Administrators must restrict access to internal resources for VPN users; for example, contractors have access only to specific project folders.
· Permissible and impermissible user and group behaviors
· Policy should state that non-company related use of computers with VPN clients is prohibited; the VPN user is responsible for all activities that originate from his or her computer or logon account.
· VPN users are responsible for the physical security of their computers.
· VPN users are responsible for keeping anti-malware software on their computers up to date.
· VPN users must follow all rules established for company network access.
· VPN users must report any security incidents to the company security department within a specific time period of detection.
· VPN users must create strong passwords and change them every 90 days, when prompted.
· All VPN usage will be monitored and logged. Policy violations by VPN users .

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
2. Overview
Define Virtual Private Networks (VPNs).
Deploy User VPNs.
Deploy Site VPNs.
Understand standard VPN techniques.
Understand the types of VPN systems.
3. Define Virtual Private
Networks
Characteristics of VPNs:
Traffic is encrypted to prevent eavesdropping.
The remote site is authenticated.
Multiple protocols are supported over the VPN.
The connection is point to point.
4. Define Virtual Private
Networks
To access a central server, VPNs may require authentication
or that both ends of the VPN authenticate each other.
VPNs can handle various protocols, especially application
layer protocols.
Each VPN channel is distinct and uses encryption to
separate traffic.
There are two types of VPNs, user VPNs and site VPNs.
5. Deploy User VPNs
VPNs between individual users’ machines and an
organization’s site or network are called User VPNs.
User VPNs are used for employees who either travel or
telecommute.
The VPN server may either be the organization’s firewall or
a separate VPN server.
6. Deploy User VPNs
While establishing a VPN, the site will request user
authentication.
On successful authentication, the user is allowed to access
the internal network.
Although the user has a VPN connection back to the
organization, they still have access to the Internet.
8. Benefits of User VPNs
Employees who are traveling can access e-mail, files, and
internal systems without expensive equipment.
Employees working from home can access the network’s
services, just as employees working from within the
organization’s facilities.
9. Issues with User VPNs
User VPNs, if optimally utilized, can reduce an
organization’s costs.
Significant security risks and implementation issues must
be addressed.
The largest concern for security is the employee’s
simultaneous connection to the Internet. The risk of
malicious code being sent through the computer is high.
10. Issues with User VPNs
Use of Trojan horse program to access an
organization’s internal network.
11. Issues with User VPNs
User VPNs require paying the same attention to user
management issues as internal systems.
The use of a two-factor authentication process is
recommended, since VPN permits access to internal
resources.
Additional support for VPN users must include a personal
firewall and updated anti-virus software to protect the
internal network.
12. Managing User VPNs
Managing user VPNs is primarily an issue of managing the
users and their computer systems.
The appropriate user management procedures should be in
place and followed during employee separation.
A good anti-virus software package must be installed on
the user’s computer.
13. Deploy Site VPNs
Site VPNs allow organizations to connect locations without
the cost of expensive leased lines.
Site VPNs authenticate each other with the use of
certificates or shared secrets.
Site VPNs save costs.
14. Deploy Site VPNs
Issues:
Policies and restrictions allow the organization to limit what a
remote site can access or do once connected.
VPNs are an extension of the company’s sites. A weak remote
site is a risk, as it allows an intruder to access the internal
network.
A coherent and logical IP addressing scheme should be used
for all sites.
15. Deploy Site VPNs
Managing site VPNs:
Monitoring the site ensures smooth communication between
the sites and compliance with the policies.
Routes to remote sites will need to be created on the internal
network. They should be well documented to ensure that they
are not deleted.
16. Understand Standard VPN
Techniques
A VPN comprises four key components:
VPN server
Encryption algorithms
Authentication system
VPN protocol
17. Understand Standard VPN
Techniques
A proper VPN architecture depends on properly identifying its
requirements, including:
The length of time for which information should be protected.
The number of simultaneous user connections.
The types of user connection expected.
18. Understand Standard VPN
Techniques
A proper VPN architecture depends on properly identifying
its requirements, including (continued):
The number of remote site connections.
The types of VPNs that will need to connect.
The amount of traffic to and from remote sites.
The security policy governing the security configuration.
19. VPN Server
The VPN server is the computer system that acts as the end
for the VPN.
Most VPN software vendors should be able to provide a
recommended processor speed and memory configuration
based on the number of simultaneous VPN connections.
Some vendors also provide a means of fail-over and allow
for redundant VPN servers.
21. Encryption Algorithms
The encryption used on the VPN should be a well-known,
strong algorithm.
If an intruder successfully intercepts a VPN communication,
it indicates that they:
Must have a sniffer on the path traveled by the packets, which
captures the entire session.
Have substantial computing power to brute-force the key and
decrypt it.
22. Authentication System
The VPN authentication system should be a two-factor
system.
Users can be authenticated either by what they are, have
or know.
Smart cards with a PIN or password are a good two-factor
combination for authenticating users.
If an organization chooses to use only passwords for the
VPN, they should be strong and changed on a regular basis.
23. VPN Protocol
In general, a standard protocol versus a proprietary
protocol should be used with VPN. IPSec is the current
standard for VPN.
The primary alternative to IPSec is SSL (Secure Socket
Layer).
24. Understand the Types of VPN
Systems
The primary types of VPN systems are:
Hardware systems
Software systems
Web-based systems
25. Hardware Systems
A hardware appliance should be used as the VPN server.
This appliance runs the manufacturer’s software and may
include some special hardware to improve the encryption
capability of the system.
26. Hardware Systems
Benefits are:
Speed: The hardware is most likely optimized to support the
VPN and thus will provide a speed advantage over a general-
purpose computer system.
Increased capacity: This translates into an ability to handle a
greater number of simultaneous VPN connections.
Security: If the hardware appliance has been specifically built
for the VPN application, all extraneous software and processes
must be removed from the system.
27. Software Systems
Software VPNs are loaded on a general-purpose computer
system.
They may be either installed on a system dedicated to the
VPN or in conjunction with other software, such as a firewall.
Software VPNs can be used in the same manner as the
hardware VPNs. Software is available for handling user VPNs
as well as site VPNs.
28. Web-based Systems
Using web-based VPNs does not require software to be
loaded on the client, thus decreasing the administrative and
managerial workload.
Web-based VPNs are limited to what applications can be
used and how the client connects to them.
29. Summary
VPNs may require authentication to access a central server
or that both VPN ends authenticate each other.
There are two types of VPNs: user VPNs and site VPNs.
While establishing a VPN, the site will request user
authentication. Successful authentication allows the user to
access the internal network.
Although the user has a VPN connection back to the
organization, they still have access to the Internet.
