Network security hardening by using attack graph can be done. Some network security hardening model described in this paper is based on exploit dependency graphs, dynamic programming and genetic algorithm. The work of our future is to improve network security hardening model and make simulation studies. Optimal network hardening is NP complete problem, which is not possible when using the exact search method and the best way to prevent the exploitation is to remove the initial attribute that causes exploitation. Because attackers often achieve their goals through multiple exploits, network vulnerability analysis must consider the combined impact of the vulnerability. Exploiting sequence analysis is a good first start. But what is really needed are explicit and managed network hardening options that provide safety guarantees, as we describe here.

are chosen for vulnerability testing. Each IP address is selected at random to ensure unbiased results. The network vulnerability scanner Nessus [15] was used to scan the IP addresses for vulnerabilities. Nessus organises the vulnerabilities for any given IP address into five categories; total vulnerabilities; high level vulnerabilities; medium level vulnerabilities; low level vulnerabilities and open ports [16]. Nessus maps all vulnerabilities with a Common Vulnerability Scoring System (CVSS) equal to or greater than 7 into a “High” severity, 4 to 6.9 into a “Medium” severity and lower than 4 into a “Low” severity [17]. The same five categories have been used for this study.

INFLUENCE OF GLOBAL SECURITY ENVIRONMENT
ON COLLECTIVE SECURITY AND DEFENCE SCIENCE

INFLUENCE OF GLOBAL SECURITY ENVIRONMENT ON COLLECTIVE SECURITY AND DEFENCE SCIENCE

Hybrid warfare and asymmetric security threats are very close and they mark the contemporary global security environment. The common point of analysis of both phenomena could be raised upon Hart’s (Hart 1954) view of a winning strategy recognised as an indirect approach with different forms of unarmed means, which effectively demolish the psychological and psychical balance of an opponent and lead to his defeat. The logic of hybrid and asymmetric warfare can basically be recognised through the Chaos and Network-centric theories of conflict management (Korybko 2015; Darius 2014; Shahskov 2011; Mann 1992). In addition, the network-centric warfare theory is also in correlation with hybrid and asymmetric endangerment of security, relying upon modern technologies, cyberspace networks and soft power mechanisms (Arquilla and Ronfeldt 2001; Cebrowski and Garstka 1998). Through the analyses of subjects, determinants, as well areas and aims of acting (Mitrović 2017a), it could be concluded that hybrid and asymmetric warfare closely correlate in areas of conceptual approach of conflict management, acting subjects (which aren’t predominantly state centralised), flexibility, adaptability, unconventionality, means and methods, ways of acting, choosing of targets, communication strategy, mobilisation of supporters and new members. Hybrid as well as asymmetric security endangerment act mostly on the most vulnerable, critical society components, resources or infrastructures that we consider wider socio-psychologically, economically, and politically components or more concrete acts against elements of infrastructure, personal safety and daily life activities, with psychological effects afterwards (Mitrović 2018). From all of the above, it could be concluded that hybrid and asymmetric endangerment of security is either not a new phenomenon or has been achieved through globalisation.

False Data Detection in Wireless Network using Dynamic Security Protocol

False Data Detection in Wireless Network using Dynamic Security Protocol

In this paper, we present a comprehensive overview of Dynamic security protocol concept in wireless sensor networks. We survey the state-of-the-art data aggregation protocols and categorized them based on network topology and security. Although the presented research addresses the many problems of data aggregation, there are still many research areas that needs to be associated with the DSP, especially from the security point of view. As for the general data aggregation concept, the relation between routing mechanisms and DS protocols have been well studied as they are highly correlated topics. In addition to diffusion and tree- based data aggregation protocols, many cluster-based data aggregation protocols that route aggregated data over cluster heads have been proposed. Although, these protocols shown to be very efficient in static networks in which the cluster structures do not change for a sufficiently long time, in dynamic networks they perform quite poorly. Hence, data aggregation in dynamic environments is a possible future research direction. The impact of sensor node heterogeneity over the data aggregation protocols is another unexplored research area [10]. The protocols that use powerful sensor

FileRunner Security Overview. An overview of the security protocols associated with the FileRunner file delivery application

The Sohonet global network is built entirely using private point to point connections, and only touches the public internet at specific, controlled gateway points. Sohonet maintains internal security of the network using a number of perimeter network security technologies. These protect the Sohonet network from the outside world and give us additional visibility and control over data crossing the boundary between Sohonet and other networks. We use a range of commercial and in-house developed technologies to continuously scrutinize our own network for these performance and security issues. These include custom IDS (intrusion detection systems) within the network, passive and active scanning of devices on the network and automatic trend monitoring and detection.

systems). There is a lot of hardware which could provide the similar functions as well, such as hardware firewalls, hardware dongle, etc.. However, all of the tools mentioned above require to be supervised by specifically trained human. Due to the different quality of PXE system users, the protection of PXE system and data is always stopped by personal reasons for which instance users usually close the firewalls. Moreover, different standards between internal and external system also make the security of system ineffective. According to recent reports, sensitive data leakages are mostly caused by personal error operating and low awareness of protection. They are even not aware of their confidential data being exposed to hackers and other illegal intruders. The emergence of situation mentioned above is mainly due to the imperfect combination between security management and control of the majority of data security systems, currently. In order to solve these problems and reduce data leakage occurring, this paper proposes an approach to construct a PXE based data security system to meet the storage security requirement.

Adaptive Security Modules in Incrementally Deployed Sensor Networks

Adaptive Security Modules in Incrementally Deployed Sensor Networks

This study presented an adaptive security design including two security modules to secure communication in sensor networks. The basic network security depends on the primary security module, where new incoming nodes can be authenticated by their neighboring nodes. The network can reinforce insecure sensing regions by deploying new sensor nodes. The primary security design triggers the establishment of secure links and broadcast authentication between neighbour nodes. Based on the primary security design, monitor mechanisms, alarm return protocols, and trust evaluation methods in the malicious node detection module enhance the security in sensor network. The proposed alarm return protocols efficiently look for suspect sensor nodes. Trust value evaluation performed by the BS is required to judge malicious nodes. The advance security design can achieve malicious node detection and prevention. Consequently, the network outperforms other secure architectures of sensor networks in detecting and eliminating external and internal malicious nodes. This paper also analyzes the performance of the proposed security modules in terms of their storage, computation, and communication overhead. When the dynamic authentication is performed in the sensor networks, the performance results are acceptable.

Impact of Coordinator Mobility in a Zigbee/IEEE 802.15.4 Based Wireless Personal Area Network

Impact of Coordinator Mobility in a Zigbee/IEEE 802.15.4 Based Wireless Personal Area Network

ABSTRACT: A network which links a number of distributed low-power sensor nodes together, with every node devoted to a previously defined operation can be seen as a Wireless Sensor Network (WSN). The network must have the ability of collecting and transmitting the data created by end nodes effectively. The wide parts of Zigbee based LR- WPAN (Low Range-Wireless Personal Area Network) are- routers, coordinator and end devices. In this research paper the writers focussed on Zigbee based LR-WPAN and examined the impact of static and dynamic condition of Zigbee PAN Coordinator on the network performance. Here the evaluation is done on 3 topologies such as- mesh, star and tree with the support of Riverbed simulator. Writers advised that rather than building the dynamic end devices, the coordinator can move throughout the network region more easily, providing better performance of global network on static coordinator network with respect to end to end delay and throughput. For various configurations, different effects on network parameters are achieved. The primary objective of this work is to measure, by simulations, the impact of coordinator mobility in a ZigBee/IEEE 802.15.4 based wireless personal area network (PAN) and permit the people to form the network configuration as per the need and performance achieved here.

The new database of the Global Terrestrial Network for Permafrost (GTN-P)

The new database of the Global Terrestrial Network for Permafrost (GTN-P)

The GTN-P experienced substantial growth at the begin- ning of the 21st century. About 350 boreholes for temper- ature monitoring were established and a considerable num- ber of active layer depth observations were collected during the 4th International Polar Year (IPY) from March 2007 to March 2009 (Brown, 2010). Efforts of the IPA and the GTN- P at the end of the IPY resulted in reports on the thermal state of permafrost in high latitudes and high altitudes which were called the “IPA snapshot” (Christiansen et al., 2010; Romanovsky et al., 2010a; Smith et al., 2010; Vieira et al., 2010; Zhao et al., 2010). The Geological Survey of Canada (GSC) also invested great efforts in collecting and storing thermal permafrost data from the western Arctic for GTN-P. The TSP (Brown et al., 2010) and CALM (Shiklomanov et al., 2008) programs oversee the collection of permafrost tem- perature and active layer thickness data from Arctic, Antarc- tic and mountain permafrost regions. These programs pro- vide the majority of the content to the GTN-P Database (Fig. 1). Both TSP and CALM provide an online data repos- itory and are actively expanding observational networks. However, all existing permafrost repositories so far were conceived as rather static aggregations of data, and the mod- ern permafrost community lacks a dynamic database with the capability to interlink the permafrost community and scien- tists working in other fields of research such as climate mod- elers, biologists or engineers.

Social Network with Dynamic Identity-based Broadcast Encryption using Security Tree

Identity-Based Broadcast Encryption has some problem. First, the maximum number of users should be predetermined. Second, each receiver must know all of the receivers. However, it is natural that each receiver knows only his own information. To solve these problems, the concept of Dynamic Identity-Based Broadcast Encryption was introduced by Jiang [7]. This scheme consists of four algorithms: Setup, Extract, Encrypt and Decrypt.

Dynamic Threat Assessment for Prioritising Computer Network Security

Dynamic Threat Assessment for Prioritising Computer Network Security

From equations 1 and 2 it is clear that in order to successfully prioritise, one requires a differentiating factor(s) between a set of devices at the same criticality level, otherwise the VP for assets will remain undetermined, where large numbers of devices are assigned to the same criticality level. One way of achieving such differentiation is to identify and analyse dynamic risks to individual devices and then prioritise the application of security services based upon these perceived risks. Numerous techniques such as: (Alberts and Dorofee), (Meier et al. 2003), (Schneier 1999), (Salter et al. 1998), (Surdu et al. 2003) and (Moore 2001) exist for the identification, analysis and ranking of risks in a network scenario. However a major limitation with all of these techniques is that they assume an exhaustive search of the problem space (i.e. identify individual risk(s) to device(s) and then quantify these based upon the attacker model), which can be vast and complex in the case of security vulnerabilities in modern IT networks. Other work detailing techniques to reduce the risk due to the rapid exploitation of software vulnerabilities is given in (Arora et al. 2004), however this does not consider prioritisation as a strategy.

DYNAMIC SECURITY FOR THE NEW NETWORK DATA CENTER

DYNAMIC SECURITY FOR THE NEW NETWORK DATA CENTER

Data center administrators must support a wide array of application types, including distributed, Web, client/server, legacy, and thin-client technologies such as virtual desktop infrastructure (VDI). It is not feasible to maintain a separate security infrastructure per protected application. However, using Juniper technologies such as SA Series SSL VPN Appliances, Juniper Networks IC Series Unified Access Control Appliances, and Junos Pulse, administrators can streamline application access control by allowing the different enforcement systems to connect with identity stores and enforce policy on the full spectrum of enterprise applications. SA Series appliances interoperate with leading VDI products, including VMware’s View Manager and Citrix’s XenDesktop, giving enterprises vendor choice and deployment flexibility.

Research on the Status of Wireless Self organizing Network

Research on the Status of Wireless Self organizing Network

The security weakness of the self-organizing network has always existed for a long time. In the transmission channel, compared with the fixed cable channel, the wireless channel is more susceptible to external interference, anyone can invade the network for network monitoring. Second, because it is dynamic topology, so the nodes in the network if the outside of the intercept, and packaged into a node with the virus information, and then you can re-join the network. From the entire network of internal attacks, resulting in the entire network of paralysis. Finally, the most important point is that there are many loopholes in the network security protocol of the wireless ad hoc network. Since the WEP protocol, the WEB 802.11li protocol has made some improvements to the protocol of the wireless ad hoc network and has solved some potential loopholes, but the loopholes are still grim.
