Enterprise Integrated Security Platform: A Comparison of Remote Access And Extranet Virtual Private Networks
The Internet has created unprecedented opportunities for both organizations and individuals. However, these opportunities also have created a double-edge sword as organizations attempt to connect trading partners, customers, and remote users while providing adequate security measures that are flexible and cost-effective. This paper explores why secured socket layer (SSL) may be better tool for secured remote access and extranets by comparing it to internet protocol security virtual private networks (IPSec-based VPNs)
Managing Access Control in Virtual Private Networks
Virtual Private Network technology allows remote network users to benefit from resources on a private network as if their host machines actually resided on the network. However, each resource on a network may also have its own access control policies, which may be completely unrelated to network access. Thus users� access to a network (even by VPN technology) does not guarantee their access to the sought resources. With the introduction of more complicated access privileges, such as delegated access, it is conceivable for a scenario to arise where a user can access a network remotely (because of direct permissions from the network administrator or by delegated permission) but cannot access any resources on the network. There is, therefore, a need for a network access control mechanism that understands the privileges of each remote network user on one hand, and the access control policies of various network resources on the other hand, and so can aid a remote user in accessing these resources based on the user\u27s privileges. This research presents a software solution in the form of a centralized access control framework called an Access Control Service (ACS), that can grant remote users network presence and simultaneously aid them in accessing various network resources with varying access control policies. At the same time, the ACS provides a centralized framework for administrators to manage access to their resources. The ACS achieves these objectives using VPN technology, network address translation and by proxying various authentication protocols on behalf of remote users
Managing and Securing Business Networks in the Smartphone Era
This paper discusses the impact of user owned mobile computing devices (smartphones, tablets, and future devices like Google Glass) on management and security of the corporate network. Personally owned portable computing devices are widely used at work and create a porous network perimeter for the enterprise network. The paper reviews corporate policies posted on websites along with research papers and corporate whitepapers to develop a comprehensive user owned mobile computing device policy. This is a rapidly evolving topic that has not been researched in the business academic literature. We survey trade journals and corporate websites for information regarding this policy and make recommendations that can be applied by business managers
Integrated security infrastructures for law enforcement agencies
Published online: 22 June 2013.
This paper is an improved version of “Security Infrastructures: Towards the INDECT System Security” from the same authors, presented in the 5th International Conference on Multimedia Communication Services & Security (MCSS 2012), Krakow (Poland), May 31- June 1, 2012.This paper provides an overview of the security architecture for Law Enforcement Agencies (LEAs) designed by the INDECT project, and in particular the security infrastructures that have been deployed so far. These security infrastructures can be organized in the following main areas: Public Key Infrastructure (PKI) and user management, communications security, and new cryptographic algorithms. This paper presents the new ideas, architectures and deployed testbeds for these areas. In particular, it explains the inner structure of the INDECT PKI employed for federated identity management, the different technologies employed in the VPN testbed, the INDECT Block Cipher (IBC) – a novel cryptographic algorithm that has being integrated into OpenSSL library, and how IBC-enabled TLS/SSL sessions and X.509 certificates are employed to protect INDECT applications. All proposed mechanisms have been designed to work in an integrated fashion as the security foundation of all systems being developed by the INDECT project for LEAs.This work has been funded by the EU Project INDECT (Intelligent information system supporting observation, searching and detection for security of citizens in urban environment)—grant agreement number: 218086
A Study on Security Attributes of Software-Defined Wide Area Network
For organizations to communicate important data across various branches, a reliable Wide Area Network (WAN) is important. With the increase of several factors such as usage of cloud services, WAN bandwidth demand, cost of leased lines, complexity in building/managing WAN and changing business needs led to need of next generation WAN. Software-defined wide area network (SD- WAN) is an emerging trend in today’s networking world as it simplifies management of network and provides seamless integration with the cloud. Compared to Multiprotocol Label Switching (MPLS) majorly used in traditional WAN architecture, SD-WAN incurs less cost, highly secure and offers great performance. This paper will mainly focus to investigate this next-generation WAN’s security attributes as security plays a crucial role in SD-WAN implementation. The goal of the paper is to analyze SD-WAN security by applying principles of CIA triad principle. Comparison of SD-WAN products offered by three different vendors in SD-WAN market with respect to its security is another important area that will be covered in this paper

Systemic Risk and Vulnerability Analysis of Multi-cloud Environments
With the increasing use of multi-cloud environments, security professionals
face challenges in configuration, management, and integration due to uneven
security capabilities and features among providers. As a result, a fragmented
approach toward security has been observed, leading to new attack vectors and
potential vulnerabilities. Other research has focused on single-cloud platforms
or specific applications of multi-cloud environments. Therefore, there is a
need for a holistic security and vulnerability assessment and defense strategy
that applies to multi-cloud platforms. We perform a risk and vulnerability
analysis to identify attack vectors from software, hardware, and the network,
as well as interoperability security issues in multi-cloud environments.
Applying the STRIDE and DREAD threat modeling methods, we present an analysis
of the ecosystem across six attack vectors: cloud architecture, APIs,
authentication, automation, management differences, and cybersecurity
legislation. We quantitatively determine and rank the threats in multi-cloud
environments and suggest mitigation strategies.Comment: 27 pages, 9 figure
Security architecture for law enforcement agencies
In order to carry out their duty to serve and protect, law enforcement agencies
(LEAs) must deploy new tools and applications to keep up with the pace of evolving
technologies. However, police information and communication technology (ICT) systems
have stringent security requirements that may delay the deployment of these new applications,
since necessary security measures must be implemented first. This paper presents an integrated
security architecture for LEAs that is able to provide common security services to novel and
legacy ICT applications, while fulfilling the high security requirements of police forces. By
reusing the security services provided by this architecture, new systems do not have to
implement custom security mechanisms themselves, and can be easily integrated into existing
police ICT infrastructures. The proposed LEA security architecture features state-of-the-art
technologies, such as encrypted communications at network and application levels, or multifactor
authentication based on certificates stored in smart cards.Web of Science7517107321070
