A solution based on SIP secured with TLS was tested on two IP based architectures. This included the development of a prototype test-bed in which various operating scenarios (such as cryptographic options, various IP-based architectures and fault tolerance) were demonstrated. The objective of this project was to design and test a secure IP-based architecture suitable for short duration transactions. Thus dependencies between specific security problems can be considered in a comprehensive way. A Security Pattern System provides linkage between Security Patterns. We show that recent security approaches are not sufficient and describe how Security Patterns contribute to the overall process of security engineering. Hence, we propose to apply the pattern approach to the security problem. Thus novices can benefit from know-how and skills of experts. Patterns literally capture the experience from experts in a structured way. The Pattern Community recognized this problem, too.

Whereas scientists work on formal approaches for the specification and verification of security requirements, practitioners have to meet the users' requirements.

At present, there is a huge gap between theory and the code of practice. The recently increasing occurrence of severe attacks has shown, however, that we will still need quite some time and effort to reach security standards of IT systems alike the standard already usual in other fields. We suggest ways to mitigate each of the discovered vulnerabilities.Ĭonducting digital business requires secure network and application architectures. In some cases, the attacker can also steal the VPN user’s username and password. We find that the VPN clients have various configuration flaws, which an attacker can exploit to strip off traffic encryption or to bypass authentication of the VPN gateway. We analyze common VPN protocols and implementations on Windows, macOS and Ubuntu. The focus is on how the client applications set up VPN tunnels, and how the service providers instruct users to configure generic client software. In this paper, we study the security of such commercial VPN services. Thus, they hide the client’s real IP address from online services, and they also shield the user’s connections from perceived threats in the access networks. The VPN services route the client’s traffic over an encrypted tunnel to a VPN gateway in the cloud. Internet users increasingly rely on commercial virtual private network (VPN) services to protect their security and privacy. The purpose of creating such a WAN is to allow the resources of a company to be remotely accessed.
The purpose of this paper is to serve as a basis when creating an enterprise WAN which connects sites and users together using VPN technology. In order to decide what VPN solutions to choose for different parts of the enterprise infrastructure, the chosen solution should be the one that best meets the requirements of the enterprise. These categories often overlap each other. VPNs can be categorized as Secure or Trusted VPNs, Client-based or Web-based VPNs, Customer Edge-based or Provider Edge-based VPNs, or Outsourced or In-house VPNs. There are many different VPN solutions out there, and just deciding which one to choose can be difficult since they all have advantages and disadvantages. A virtual private network (VPN) can be defined as a way to provide secure communication between members of a group through use of public telecommunication infrastructure, maintaining privacy through the use of a tunneling protocol and security procedures.
