In the near future, billions of new smart devices will connect the big network of the Internet of Things, playing an important key role in our daily life. Allowing IPv6 on the low-power resource constrained devices will lead research to focus on novel approaches that aim to improve the efficiency, security and performance of the 6LoWPAN adaptation layer. This work in progress paper proposes a hardware-based Network Packet Filtering (NPF) and an IPv6 Link-local address calculator which is able to filter the received IPv6 packets, offering nearly 18% overhead reduction. The goal is to obtain a System-on-Chip implementation that can be deployed in future IEEE 802.15.4 radio modules.

Cross Site Scripting attack (XSS) is the computer security threat which allows the attacker to get access over the sensitive information, when the javaScript, VBScript, ActiveX, Flash or HTML which is embedded in the malicious XSS link gets executed. In this paper, we authors have discussed about various impacts of XSS, types of XSS, checked whether the site is vulnerable towards the XSS or not, discussed about various tools for examining the XSS vulnerability and summarizes the preventive measures against XSS.

Software development and web applications have become fundamental in our lives. Millions of users access these applications to communicate, obtain information and perform transactions. However, these users are exposed to many risks; commonly due to the developer's lack of experience in security protocols. Although there are many researches about web security and hacking protection, there are plenty of vulnerable websites. This article focuses in analyzing 3 main hacking techniques: XSS, CSRF, and SQL Injection over a representative group of Colombian websites. Our goal is to obtain information about how Colombian companies and organizations give (or not) relevance to security; and how the final user could be affected.

Cross site scripting (XSS) is a kind of common attack nowadays. The attack patterns with the new technical like HTML5 that makes detection task getting harder and harder. In this paper, we focus on the browser detection mechanism integrated with HTML5 and CORS properties to detect XSS attacks with the rule based filter by using browser extensions. Further, we also present a model of composition pattern estimation system which can be used to judge whether the intercepted request has malicious attempts or not. The experimental results show that our approach can reach high detection rate by tuning our system through some frequently used attack sentences and testing it with the popular tool-kits: XSSer developed by OWASP.

Web application security has become crucially vital these days. Earlier "default allow" model was used to secure web applications but it was unable to secure web applications against plethora of attacks [1]. In contrast, more restricted security to the web applications is provided by default deny model which at first, builds a model for the particular application and then permits merely those requests that conform to that model while ignoring everything else. Besides this, a novel and effective methodology is followed that allows to analyze the validity of application requests and further results in the generation of semi structured XML cases for the web applications. Furthermore, mature and resilient XML cases are generated by employing learning techniques. This system will further be gauged by examining that XML file containing cases are in correct accordance with the XML format or not. Moreover, the distinction between malicious and non-malicious traffic is carried out carefully. Results have proved its efficacy of rule generation employing access traffic log of cross site scripting (XSS), SQL injection, HTTP Request Splitting, HTTP response splitting and Buffer overflow attacks.

Content Security Policy (CSP) is powerful client-side security layer that helps in mitigating and detecting wide ranges of Web attacks including cross-site scripting (XSS). However, utilizing CSP by site administrators is a fallible process and may require significant changes in web application code. In this paper, we propose an approach to help site administers to overcome these limitations in order to utilize the full benefits of CSP mechanism which leads to more immune sites from XSS. The algorithm is implemented as a plugin. It does not interfere with the Web application original code. The plugin can be “installed” on any other web application with minimum efforts. The algorithm can be implemented as part of Web Server layer, not as part of the business logic layer. It can be extended to support generating CSP for contents that are modified by JavaScript after loading. Current approach inspects the static contents of URLs.

In last twenty years, use of internet applications, web hacking activities have exaggerated speedily. Organizations facing very significant challenges in securing their web applications from rising cyber threats, as compromise with the protection issues don't seem to be reasonable. Vulnerability Assessment and Penetration Testing (VAPT) techniques help them to go looking out security loopholes. These security loopholes could also be utilized by attackers to launch attacks on technical assets. Thus it is necessary ascertain these vulnerabilities and install security patches. VAPT helps organization to determine whether their security arrangements are working properly. This paper aims to elucidate overview and various techniques used in vulnerability assessment and penetration testing (VAPT). Also focuses on making cyber security awareness and its importance at various level of an organization for adoption of required up to date security measures by the organization to stay protected from various cyber-attacks.

Web applications are used on a large scale worldwide, which handles sensitive personal data of users. With web application that maintains data ranging from as simple as telephone number to as important as bank account information, security is a prime point of concern. With hackers aimed to breakthrough this security using various attacks, we are focusing on SQL injection attacks and XSS attacks. SQL injection attack is very common attack that manipulates the data passing through web application to the database servers through web servers in such a way that it alters or reveals database contents. While Cross Site Scripting (XSS) attacks focuses more on view of the web application and tries to trick users that leads to security breach. We are considering three tier web applications with static and dynamic behavior, for security. Static and dynamic mapping model is created to detect anomalies in the class of SQL Injection and XSS attacks.

Cross Site Scripting (XSS) and clickjacking have been ranked among the top web application threats in recent times. This paper introduces XBuster - our client-side defence against XSS, implemented as an extension to the Mozilla Firefox browser. XBuster splits each HTTP request parameter into HTML and JavaScript contexts and stores them separately. It searches for both contexts in the HTTP response and handles each context type differently. It defends against all XSS attack vectors including partial script injection, attribute injection and HTML injection. Also, existing XSS filters may inadvertently disable frame busting code used in web pages as a defence against clickjacking. However, XBuster has been designed to detect and neutralize such attempts.

Online Social Networks (OSNs) are continuously suffering from the negative impact of Cross-Site Scripting (XSS) vulnerabilities. This paper describes a novel framework for mitigating XSS attack on OSN-based platforms. It is completely based on the request authentication and view isolation approach. It detects XSS attack through validating string value extracted from the vulnerable checkpoint present in the web page by implementing string examination algorithm with the help of XSS attack vector repository. Any similarity (i.e. string is not validated) indicates the presence of malicious code injected by the attacker and finally it removes the script code to mitigate XSS attack. To assess the defending ability of our designed model, we have tested it on OSN-based web application i.e. Humhub. The experimental results revealed that our model discovers the XSS attack vectors with low false negatives and false positive rate tolerable performance overhead.

Named Data Networking (NDN), a clean-slate data oriented Internet architecture targeting on replacing IP, brings many potential benefits for content distribution. Real deployment of NDN is crucial to verify this new architecture and promote academic research, but work in this field is at an early stage. Due to the fundamental design paradigm difference between NDN and IP, Deploying NDN as IP overlay causes high overhead and inefficient transmission, typically in streaming applications. Aiming at achieving efficient NDN streaming distribution, this paper proposes a transitional architecture of NDN/IP hybrid network dubbed Centaur, which embodies both NDN's smartness, scalability and IP's transmission efficiency and deployment feasibility. In Centaur, the upper NDN module acts as the smart head while the lower IP module functions as the powerful feet. The head is intelligent in content retrieval and self-control, while the IP feet are able to transport large amount of media data faster than that if NDN directly overlaying on IP. To evaluate the performance of our proposal, we implement a real streaming prototype in ndnSIM and compare it with both NDN-Hippo and P2P under various experiment scenarios. The result shows that Centaur can achieve better load balance with lower overhead, which is close to the performance that ideal NDN can achieve. All of these validate that our proposal is a promising choice for the incremental and compatible deployment of NDN.

Increase in M2M use cases, the availability of narrow band spectrum with operators and a need for very low cost modems for M2M applications has led to the discussions around what is called as Cellular IOT (CIOT). In order to develop the Cellular IOT network, discussions are focused around developing a new air interface that can leverage narrow band spectrum as well as lead to low cost modems which can be embedded into M2M/IOT devices. One key issue that arises during the development of a clean slate CIOT network is that of coexistence with the 4G networks. In this paper we explore architectures for Cellular IOT and 4G network harmonization that also addresses the one key requirement of possibly using narrow channels for IOT on the existing 4G networks and not just as a separate standalone Cellular IOT system. We analyze the architectural implication on the core network load in a tightly coupled CIOT-LTE architecture propose a offload mechanism from LTE to CIOT cells.

As the amount of mobile devices populating the Internet keeps growing at tremendous pace, context-aware services have gained a lot of traction thanks to the wide set of potential use cases they can be applied to. Environmental sensing applications, emergency services, and location-aware messaging are just a few examples of applications that are expected to increase in popularity in the next few years. The MobilityFirst future Internet architecture, a clean-slate Internet architecture design, provides the necessary abstractions for creating and managing context-aware services. Starting from these abstractions we design a context services framework, which is based on a set of three fundamental mechanisms: an easy way to specify context based on human understandable techniques, i.e. use of names, an architecture supported management mechanism that allows both to conveniently deploy the service and efficiently provide management capabilities, and a native delivery system that reduces the tax on the network components and on the overhead cost of deploying such applications. In this paper, we present an emergency alert system for vehicles assisting first responders that exploits users location awareness to support quick and reliable alert messages for interested vehicles. By deploying a demo of the system on a nationwide testbed, we aim to provide better understanding of the dynamics involved in our designed framework.

The Internet routing ecosystem is facing substantial scalability challenges on the data plane. Various “clean slate” architectures for representing forwarding tables (FIBs), such as IPv6, introduce additional constraints on efficient implementations from both lookup time and memory footprint perspectives due to significant classification width. In this work, we propose an abstraction layer able to represent IPv6 FIBs on existing IP and even MPLS infrastructure. Feasibility of the proposed representations is confirmed by an extensive simulation study on real IPv6 forwarding tables, including low-level experimental performance evaluation.

Internet of Things(IoT) is the next big boom in the networking field. The vision of IoT is to connect daily used objects (which have the ability of sensing and actuation) to the Internet. This may or may or may not involve human. IoT field is still maturing and has many open issues. We build up on the security issues. As the devices have low computational power and low memory the existing security mechanisms (which are a necessity) should also be optimized accordingly or a clean slate approach needs to be followed. This is a survey paper to focus on the security aspects of IoT. We further also discuss the open challenges in this field.

Control theory and SDN (Software Defined Networking) are key components for NFV (Network Function Virtualization) deployment. However little has been done to use a control-theoretic approach for SDN and NFV management. In this demo, we describe a use case for NFV management using control theory and SDN. We use the management architecture of RINA (a clean-slate Recursive InterNetwork Architecture) to manage Virtual Network Function (VNF) instances over the GENI testbed. We deploy Snort, an Intrusion Detection System (IDS) as the VNF. Our network topology has source and destination hosts, multiple IDSes, an Open vSwitch (OVS) and an OpenFlow controller. A distributed management application running on RINA measures the state of the VNF instances and communicates this information to a Proportional Integral (PI) controller, which then provides load balancing information to the OpenFlow controller. The latter controller in turn updates traffic flow forwarding rules on the OVS switch, thus balancing load across the VNF instances. This demo demonstrates the benefits of using such a control-theoretic load balancing approach and the RINA management architecture in virtualized environments for NFV management. It also illustrates that the GENI testbed can easily support a wide range of SDN and NFV related experiments.

Simple connectivity and data requirements together with high lifetime of battery are the main issues for the machine-to-machine (M2M) communications. 3GPP focuses on three main licensed standardizations based on Long Term Evolution (LTE), GSM and clean-slate technologies. The paper considers the last one and proposes a modified slotted-Aloha method to increase the capability of supporting a massive number of low-throughput devices. The proposed method increases the access rate of users belonging to each class considered in the clean-slate standard and consequently the total throughput offered by the system. To derive the mean access rate per class, we use the Markov chain approach and simulation results are provided for scenarios with different data rate and also in terms of cell average delay.

Named-Data Networking (NDN) is the most prominent proposal for a clean-slate proposal of Future Internet. Nevertheless, NDN routing schemes present scalability concerns due to the required number of stored routes and of control messages. In this work, we present a controller-based routing protocol using a formal method to unambiguously specify, and validate to prove its correctness. Our proposal codes signaling information on content names, avoiding control message overhead, and reduces router memory requirements, storing only the routes for simultaneously consumed prefixes. Additionally, the protocol installs a new route on all routers in a path with a single route request to the controller, avoiding replication of routing information and automating router provisioning. As a result, we provide a protocol proposal description using the Specification and Description Language and we validate the protocol, proving that CRoS behavior is free of dead or live locks. Furthermore, the protocol validation guarantees that the scheme ensures a valid working path from consumer to producer, even if it does not assure the shortest path.

Internet has been being becoming the most famous and biggest communication networks as social, industrial, and public infrastructure since Internet was invented at late 1960s. In a historical retrospect of Internet's evolution, the Internet architecture continues evolution repeatedly by going through various technical challenges, for instance, in early 1990s, Internet had encountered danger of scalability, after a short while it had been overcome and successfully evolved by applying emerging techniques such as CIDR, NAT, and IPv6. Especially this paper emphasizes scalability issues as technical challenges with forecasting that Internet of things era has come. Firstly, we describe the Identifier and locator separation scheme that can achieve dramatically architectural evolution in historical perspective. Additionally, it reviews various kinds of Identifier and locator separation scheme because recently the scheme can be the major design pillar towards future of Internet architecture such as both various clean-slated future Internet architectures and evolving Internet architectures. Lastly we show a result of analysis by analysis table for future of internet of everything where number of Internet connected devices will growth to more than 20 billion by 2020.

Prior remote attestation may not be suitable to scale to the proliferation of IoT device swarms. To this end, we propose a cooperative remote attestation scheme, which validates the security state and verifies the system integrity with the cooperation of neighbor devices. The efficiency of the proposed mechanism is analyzed as a cryptographic protocol and then discussed in terms of security and scalability.

Several years ago, virtualization technologies, hypervisors were rediscovered, today virtualization is used in a variety of applications. Network operators have discovered the cost-effectiveness, flexibility,, scalability of virtualizing network functions (NFV). However, in light of current events, security breaches related to platform software manipulation the use of Trusted Computing technologies has become not only more popular but increasingly viewed as mandatory for adequate system protection. While Trusted Computing hardware for physical platforms is currently available, widely used, analogous support for virtualized environments, virtualized platforms is rare, not suitable for larger scale virtualization scenarios. Current remote, deep attestation protocols for virtual machines can support a limited amount of virtual machines before the inefficient use of the TPM device becomes a crucial bottle neck. We propose a scalable remote attestation scheme suitable for private cloud, NFV use cases supporting large amounts of VM attestations by efficient use of the physical TPM device.

In recent years, the rapid development of virtualization and container technology brings unprecedented impact on traditional IT architecture. Trusted Computing devotes to provide a solution to protect the integrity of the target platform and introduces a virtual TPM to adapt to the challenges that virtualization brings. However, the traditional integrity measurement solution and remote attestation has limitations due to the challenges such as large of measurement and attestation cost and overexposure of configurations details. In this paper, we propose the Partial Attestation Model. The basic idea of Partial Attestation Model is to reconstruct the Chain of Trust by dividing them into several separated ones. Our model therefore enables the challenger to attest the specified security requirements of the target platform, instead of acquiring and verifying the complete detailed configurations. By ignoring components not related to the target requirements, our model reduces the attestation costs. In addition, we further implement an attestation protocol to prevent overexposure of the target platform's configuration details. We build a use case to illustrate the implementation of our model, and the evaluations on our prototype show that our model achieves better efficiency than the existing remote attestation scheme.

Modern computing environments are increasingly getting distributed with one machine executing programs on the other remotely. Often, multiple machines work together to complete a task. Its important for collaborating machines to trust each other in order to perform properly. Such scenarios have brought up a key security issue of trustably and securely executing critical code on remote machines. We present a purely software based remote attestation technique XEBRA(XEn Based Remote Attestation) that guarantees the execution of correct code on a remote host, termed as remote attestation. XEBRA can be used to establish dynamic root of trust in a remote computing device using virtualization. We also show our approach to be feasible on embedded platforms by implementing it on an Intel Galileo board.

We introduce a machine learning approach for distinguishing between integrated circuits fabricated in a ratified facility and circuits originating from an unknown or undesired source based on parametric measurements. Unlike earlier approaches, which seek to achieve the same objective in a general, design-independent manner, the proposed method leverages the interaction between the idiosyncrasies of the fabrication facility and a specific design, in order to create a customized fab-of-origin membership test for the circuit in question. Effectiveness of the proposed method is demonstrated using two large industrial datasets from a 65nm Texas Instruments RF transceiver manufactured in two different fabrication facilities.
