Integrity Checking of Operating Systems with Respect to Kernel Level Malware”
To Bianca, for being who you are. Abstract Kernel-mode rootkits have gained a considerable momentum within the blackhat com- munity. They represent a considerable threat to any computer system, as they pro- vide an intruder with the ability to hide the presence of his malicious activity. These rootkits make changes to the operating system’s kernel, thereby providing particularly stealthy hiding techniques. Considering the kernel rootkit threat and other threats, the collection of reliable information from a compromised system becomes a central problem within the domain of computer security. This thesis addresses this problem. It looks at the possibility of using virtualization as a means to facilitate kernel-mode rootkit detection through integrity checking. The thesis describes several areas within the Linux kernel, which are commonly subverted by kernel-mode rootkits. It introduces the reader to the concept of virtual- ization and describes several technologies employing virtualization. The kernel-mode rootkit threat is then addressed through a description of their hiding methodologies. Some of the existing methods for malware detection are also addressed and analysed. A number of general requirements, which need to be satisfied by a general model enabling kernel-mode rootkit detection, are identified. A model addressing these requirements is suggested, and a framework implementing the model is set-up. The detection capabilities of the framework are tested on a couple of rootkits. iii Preface This report presents the results of my master thesis “Integrity checking of operating systems with respect to kernel level malware”. It is written as part of the Master de- gree (Sivilingeniør) in Computer Science at the Norwegian University of Science and Technology (NTNU), during Spring 2005. -

Technical Impacts of DNS Privacy and Security on Network Service Scenarios
- Technical Impacts of DNS Privacy and Security on Network Service Scenarios ATIS-I-0000079 | April 2020 Abstract The domain name system (DNS) is a key network function used to resolve domain names (e.g., atis.org) into routable addresses and other data. Most DNS signalling today is sent using protocols that do not support security provisions (e.g., cryptographic confidentiality protection and integrity protection). This may create privacy and security risks for users due to on-path nodes being able to read or modify DNS signalling. In response to these concerns, particularly for DNS privacy, new protocols have been specified that implement cryptographic DNS security. Support for these protocols is being rapidly introduced in client software (particularly web browsers) and in some DNS servers. The implementation of DNS security protocols can have a range of positive benefits, but it can also conflict with important network services that are currently widely implemented based on DNS. These services include techniques to mitigate malware and to fulfill legal obligations placed on network operators. This report describes the technical impacts of DNS security protocols in a range of network scenarios. This analysis is used to derive recommendations for deploying DNS security protocols and for further industry collaboration. The aim of these recommendations is to maximize the benefits of DNS security support while reducing problem areas. Foreword As a leading technology and solutions development organization, the Alliance for Telecommunications Industry Solutions (ATIS) brings together the top global ICT companies to advance the industry’s business priorities. ATIS’ 150 member companies are currently working to address network reliability, 5G, robocall mitigation, smart cities, artificial intelligence-enabled networks, distributed ledger/blockchain technology, cybersecurity, IoT, emergency services, quality of service, billing support, operations and much more. -

A Brief Study and Comparison Of, Open Source Intrusion Detection System Tools
International Journal of Advanced Computational Engineering and Networking, ISSN: 2320-2106, Volume-1, Issue-10, Dec-2013 A BRIEF STUDY AND COMPARISON OF, OPEN SOURCE INTRUSION DETECTION SYSTEM TOOLS 1SURYA BHAGAVAN AMBATI, 2DEEPTI VIDYARTHI 1,2Defence Institute of Advanced Technology (DU) Pune –411025 Email: [email protected], [email protected] Abstract - As the world becomes more connected to the cyber world, attackers and hackers are becoming increasingly sophisticated to penetrate computer systems and networks. Intrusion Detection System (IDS) plays a vital role in defending a network against intrusion. Many commercial IDSs are available in marketplace but with high cost. At the same time open source IDSs are also available with continuous support and upgradation from large user community. Each of these IDSs adopts a different approaches thus may target different applications. This paper provides a quick review of six Open Source IDS tools so that one can choose the appropriate Open Source IDS tool as per their organization requirements. Keywords - Intrusion Detection, Open Source IDS, Network Securit, HIDS, NIDS. I. INTRODUCTION concentrate on the activities in a host without considering the activities in the computer networks. Every day, intruders are invading countless homes On the other hand, NIDS put its focus on computer and organisations across the country via virus, networks without examining the hosts’ activities. worms, Trojans, DoS/DDoS attacks by inserting bits Intrusion Detection methodologies can be classified of malicious code.

Some Ethical Hacking Possibilities in Kali Linux Environment
Vol. 9, No. 4, 2019 pp. 129-149 http://doi.org/10.24368/jates.v9i4.139 21 129 Journal of Applied Technical and Educational Sciences jATES ISSN 2560-5429 http://jates.org Some ethical hacking possibilities in Kali Linux environment Petar Cisara, Robert Pinterb aUniversity of Criminal Investigation and Police Studies, Cara Dusana 196, 11080 Zemun, Serbia, [email protected] bSubotica Tech - College of Applied Sciences, Marka Oreskovica 16, 24000 Subotica, Serbia, [email protected] Abstract This paper deals with the problem of ethical hacking and security of computer systems. When we talk about security of an information system, we actually mean the primary three attributes of the system: confidentiality, integrity and availability. There are various approaches with aim to identify existing security weaknesses and security assessment. One of them is using Kali Linux operating system with its integrated effective tools specially adapted to the realization of various types of attacks. The paper gives a general overview of some Kali attacking possibilities on client and server side and highlights their specificities. The undoubted benefit of this operating system is a large collection of different hacking tools in one place which significantly facilitates vulnerability assessment and security testing. Keywords: Kali Linux; tools; attack; security; ethical hacking 1. Introduction In general, four main categories (or phases) of information security assessments can be identified (Hertzog, 2017): a vulnerability assessment, a compliance (audit) test, a traditional internal/external penetration test, and an application assessment. There are various methods with aim to identify existing security weaknesses and security assessment (Allen, 2014). -
Kevin Cardwell B L
Kevin Cardwell b l Toolkits: All-in-One Approach to Security a This talk will be on using toolkits for your pen-testing, c vulnerability assessment etc. Configuring a plethora of the different tools out there can be quite time consuming, and challenging. The focus of this talk will be to look at an alternative k solution that provides a suite of tools at boot. Until recently there was not very many toolkits, and the ones that were there did not work very well, that has changed and in this talk I will discuss the h toolkits available, and demo one of the better ones. The toolkits that will be reviewed will all be open source, and free, there are commercial solutions available, but why pay when the free ones a are more than adequate. t b r Kevin Cardwell spent 22 years in the U.S. Navy, starting off in Sound Navigation and Ranging (SONAR). He began i programming in 1987. He was fortunate enough to get on the Testing Team and got to test and evaluate Surveillance e and Weapon system software including; Remote Mine- Hunting System, Multi-System Torpedo Recognition Alert Processor (MSTRAP), Advanced Radar Periscope f Discrimination Detection System (ARPDD), Tactical Decision Support Subsystem (TDSS) and Computer Aided Dead Reckoning Tracer (CADRT). Shortly thereafter he became a software and systems engineer and was was i selected to head the team that built a Network Operation Center (NOC) that provided services to the command ashore n and ships at sea in the Norwegian Sea and Atlantic Ocean. -
