All sources, references and literature used or excerpted during elaboration of this work are properly cited and listed in complete reference to the due source. Júlia Murínová Advisor: doc. RNDr. Vlastislav Dohnal, Ph.D. iii Acknowledgement I would like to express my gratitude to doc. RNDr. Vlastislav Dohnal, Ph.D. for his guidance and help during work on this thesis. Furthermore I would like to thank my parents, friends and family for their continuous support. My thanks also belongs to my boyfriend for all his assistance and help. v Abstract The goal of this thesis is to introduce the log analysis area in general, compare available systems for web log analysis, choose an appropriate solution for sample data and implement the proposed solution. Thesis contains overview of monitoring and log analysis, specifics of application log analysis and log file formats definitions. Various available systems for log analysis both proprietary and open-source are compared and categorized with overview comparison tables of supported functionality. Based on the comparison and requirements analysis appropriate solution for sample data is chosen. The ELK stack (Elasticsearch, Logstash and Kibana) and ElastAlert framework are deployed and configured for analysis of sample application log data. Logstash configuration is adjusted for collecting, parsing and processing sample data input supporting reading from file as well as online socket logs collection. Additional information for anomaly detection is computed and added to log records in Logstash processing. -
Analysis of Web Logs and Web User in Web Mining
International Journal of Network Security & Its Applications (IJNSA), Vol.3, No.1, January 2011 ANALYSIS OF WEB LOGS AND WEB USER IN WEB MINING L.K. Joshila Grace 1, V.Maheswari 2, Dhinaharan Nagamalai 3, 1Research Scholar, Department of Computer Science and Engineering [email protected] 2 Professor and Head,Department of Computer Applications 1,2 Sathyabama University,Chennai,India 3Wireilla Net Solutions PTY Ltd, Australia ABSTRACT Log files contain information about User Name, IP Address, Time Stamp, Access Request, number of Bytes Transferred, Result Status, URL that Referred and User Agent. The log files are maintained by the web servers. By analysing these log files gives a neat idea about the user. This paper gives a detailed discussion about these log files, their formats, their creation, access procedures, their uses, various algorithms used and the additional parameters that can be used in the log files which in turn gives way to an effective mining. It also provides the idea of creating an extended log file and learning the user behaviour. KEYWORDS Web Log file, Web usage mining, Web servers, Log data, Log Level directive. 1. INTRODUCTION Log files are files that list the actions that have been occurred. These log files reside in the web server. Computers that deliver the web pages are called as web servers. The Web server stores all of the files necessary to display the Web pages on the users computer. All the individual web pages combines together to form the completeness of a Web site. Images/graphic files and any scripts that make dynamic elements of the site function. -
Elliptic Curve Cryptography in Cloud Computing Security
Elliptic curve cryptography in cloud computing security Manu Gopinathan ([email protected]) Øyvind Nygard ([email protected]) Kjetil Aune([email protected]) December 1st, 2015 1 Abstract Cloud computing is a technological advancement that has been growing swiftly during the last decade. In simple terms, cloud computing is a technology that enables shared, remote, on-demand and ubiquitous access to services through the Internet. It enables consumers to access applications and services that reside on remote servers, without having to allocate large amounts of storage space on their own computer and without the need for extensive compatibility configurations. Many such cloud applications provide services that are meant to handle sensitive user data and thus the protection of this data in terms of access and integrity is of major concern. Space- and time complexity of encryption algorithms can prove to be imperative when it comes to system performance. In this paper we will briefly present how elliptic curve cryptography (EEC) works, and then describe the advantages of it and how it can be used as an encryption solution to security related issues in cloud computing. 2 Introduction In this section we will briefly describe the notion of cloud computing to aid us in the discussion of ECC in cloud computing later. According to the National Institute of Standards and Technology (NIST), essential characteristics for a service based on the cloud computing model are [1]: 1. On-demand self-service: The consumer can provision service capabilities, such as server time and network storage, without actively interacting with the service provider. 2. -

Torrent is not seeding We are a thriving community dedicated to helping users old and new understand and use torrents. I think is stable enough. A peer or downloader becomes a seed when it starts uploading the already downloaded content for other peers to download from. Do not send - not taken into account. Please check the Accepted clients list. When it completes you switch to a torrent is not seeding and dedicate that stream to simply uploading. My upload speed limit should be all I need instead of limiting upload slots. Then add the port you selected in step 5. Torrent files contain information like the file list, sizes, pieces, etc. Every piece received is first checked against the hash. If yes, please state the libtorrent version used by your distro. However, whether to seed or not, or how much to seed, depends on the availability of downloaders and the choice of the peer at the seeding end. I tried raising my connection limits to higher and higher numbers currently at 1000, 500, 500, 500 I have a static port so I can forward it. For legal torrents try. I advice you to use only one active seeding torrent when capturing.

By moving appropriate types of files to the cloud, organizations can reduce not only the amount of storage capacity that they need to purchase, but also the operational overhead involved in managing it. In addition, the cloud enables storage capacity to be increased on demand, while charging organizations only for the amount of storage that is actually utilized. Cloud storage will bring many changes to the way enterprises manage storage. -

Napster and Gnutella marked the beginning reduce the impact of data silos as often fostered by centralized and were followed by many other P2P networks focusing on cloud storage. While the intentions of this trend are not new, the specialized application areas or novel network structures. For topic gained traction due to technological advancements, most notably blockchain networks. As a consequence, we observe that example, Freenet [2] realizes anonymous storage and retrieval. a new generation of peer-to-peer data networks emerges. In this Chord [3], CAN [4], and Pastry [5] provide protocols to survey paper, we therefore provide a technical overview of the maintain a structured overlay network topology.

Cloud Computing and Internet of Things: Issues and Developments
Proceedings of the World Congress on Engineering 2018 Vol I WCE 2018, July 4-6, 2018, London, U.K. Cloud Computing and Internet of Things: Issues and Developments Isaac Odun-Ayo, Member, IAENG, Chinonso Okereke, and Hope Orovwode Abstract—Cloud computing is a pervasive paradigm that is allows access to recent technologies and it enables growing by the day. Various service types are gaining increased enterprises to focus on core activities, instead programming importance. Internet of things is a technology that is and infrastructure. The services provided include Software- developing. It allows connectivity of both smart and dumb as-a-Service (SaaS), Platform-as–a–Service (PaaS) and systems over the internet. Cloud computing will continue to be Infrastructure–as–a–Services (IaaS). SaaS provides software relevant to IoT because of scalable services available on the cloud. Cloud computing is the need for users to procure servers, applications over the Internet and it is also known as web storage, and applications. These services can be paid for and service [2]. utilized using the various cloud service providers. Clearly, IoT Cloud users can access such applications anytime, which is expected to connect everything to everyone, requires anywhere either on their personal computers or on mobile not only connectivity but large storage that can be made systems. In PaaS, the cloud service provider makes it available either through on-premise or off-premise cloud possible for users to deploy applications using application facility. On the other hand, events in the cloud and IoT are programming interfaces (APIs), web portals or gateways dynamic. -
