Evaluation of Machine Learning Classifiers for Mobile Network Intrusion Detection Systems

Mobile malwares are increasing with the growing number of Mobile users. Mobile malwares can perform several operations which lead to cybersecurity threats such as, stealing financial or personal information, installing malicious applications, sending premium SMS, creating backdoors, keylogging and crypto-ransomware attacks. Knowing the fact that there are many illegitimate Applications available on the App stores, most of the mobile users remain careless about the security of their Mobile devices and become the potential victim of these threats. Previous studies have shown that not every antivirus is capable of detecting all the threats; due to the fact that Mobile malwares use advance techniques to avoid detection. A Network-based IDS at the operator side will bring an extra layer of security to the subscribers and can detect many advanced threats by analyzing their traffic patterns. Machine Learning(ML) will provide the ability to these systems to detect unknown threats for which signatures are not yet known. This research is focused on the evaluation of Machine Learning classifiers in Network-based Intrusion detection systems for Mobile Networks. In this study, different techniques of Network-based intrusion detection with their advantages, disadvantages and state of the art in Hybrid solutions are discussed. Finally, a ML based NIDS is proposed which will work as a subsystem, to Network-based IDS deployed by Mobile Operators, that can help in detecting unknown threats and reducing false positives. In this research, several ML classifiers were implemented and evaluated. This study is focused on Android-based malwares, as Android is the most popular OS among users, hence most targeted by cyber criminals. Supervised ML algorithms based classifiers were built using the dataset which contained the labeled instances of relevant features. These features were extracted from the traffic generated by samples of several malware families and benign applications. These classifiers were able to detect malicious traffic patterns with the TPR upto 99.6% during Cross-validation test. Also, several experiments were conducted to detect unknown malware traffic and to detect false positives. These classifiers were able to detect unknown threats with the Accuracy of 97.5%. These classifiers could be integrated with current NIDS', which use signatures, statistical or knowledge-based techniques to detect malicious traffic. Technique to integrate the output from ML classifier with traditional NIDS is discussed and proposed for future work.

Khrushchev's Beau Geste: the Return of Porkkala and its Global Significance

The return of the Porkkala naval base, which was leased to the Soviet Union at the end of World War II was unexpectedly returned in early 1956, 42 years before the USSR's lease on the area was to expire. There is no commonly accepted reason, and therefore the purpose of this work is to study the possible motives behind the return of Porkkala. These seem to have been reflected in the new foreign policy after the death of Stalin, which went far beyond returning Porkkala to Finland. The Soviet Union's courting of the non-aligned powers during this time, into which category Finland was assigned, also seems to be more than coincidence. However, the greater events of 1956, and the fact that Porkkala is remembered almost exclusively in Finland may have conspired to trap the events around Porkkala into the smaller narrative of Finnish-Soviet relations and the rise of Kekkonen to the presidency, due in no small part to his presence in negotiating the return of Porkkala. However this does not negate the message that Porkkala was intended to broadcast the USSR's new approach to neutrality. Through primary and secondary sources, gleaned from archives in Finland, memoirs of people involved, and historical literature, this thesis hopes to broaden the view that Porkkala's main and only significance lay in the changes it brought to Finnish-Soviet relations.

Invoice-kaupan edut ja haitat verrattuna tavalliseen Tax Free kauppaan

Kandidaatintutkielmani käsittelee Invoice-kauppaa ja sitä, mitä etuja siihen liittyy verrattuna tavanomaiseen tax-free kauppaan. Invoice-veronpalautusjärjestelmässä EU:n ulkopuolella asuva asiakas saa veronpalautuksen samasta liikkeestä seuraavalla asiointikerralla. Arvonlisäveronpalautukset on kuitenkin haettava puolen vuoden sisällä ostosten tekemisestä. Tavanomaisessa tax-free kaupassa asiakas saa arvonlisäveronpalautuksen rajalta poistuessaan Suomesta. Invoicea käytettäessä asiakas saa verosta isomman osan takaisin kuin tavanomaisessa tax-free kaupassa, mutta palautuksen saaminen kestää kauemmin, koska Invoicea käytettäessä veronpalautuksen voi saada vain samasta liikkeestä, missä ostokset on tehty. Tutkielmani tarkastelee aihetta kauppiaan näkökulmasta. Kauppiaan kannalta Invoicen etuna on erityisesti asiakkaiden ”koukuttaminen”, koska veronpalautukset on aina haettava samasta liikkestä, mistä tuotteet on ostettu. Näin samat asiakkaat tulevat usein samaan liikkeeseen myös seuraavilla Suomen matkoilla saadakseen veronpalautukset. Tämä tuo liikkeille usein myös uusia kanta-asiakkaita.Toisaalta on huomioitava myös Invoicen käytöstä kauppiaalle ja kassoille mahdollisesti aiheutuva lisätyö ja kustannukset. Veronpalautusten maksaminen takaisin asiakkaille ja tullissa leimattujen kuittien käsittely vie kassoilla tavanomaista enemmän aikaa ja saattaa vaatia lisää henkilökuntaa. Tutkielma on toteutettu laadullisena eli kvalitatiivisena ja tutkimusmenetelmänä on käytetty haastatteluita. Haastateltavat ovat kauppiaita Kaakkois-Suomen alueelta. Tavoitteenani oli koota mahdollisimman monipuolinen haastateltavien joukko sisältäen niin vaate- ja vapaa-ajan liikkeitä kuin sekatavara- ja päivittäistavarakauppoja. Teorialähteinä käytin yliopiston kirjastosta lainattuja kirjoja, LUT:in tietokantojen ja Edilex-tietokannan artikkeleita sekä Verohallinnon dokumentteja ja verkkojulkaisuja. Lisäksi olen hyödyntänyt tutkielmassani myös ajankohtaisia uutisia sekä erilaisten paikallis- ja aikakauslehtien artikkeleita. Tutkielmani johtopäätöksissä tulin siihen tulokseen, että kauppiaan kannalta edullisinta on käyttää samanaikaisesti sekä Invoicea että perinteistä, palautusliikeiden palveluja hyödyntävää tax-free järjestelmää. Tämä mahdollistaa liikkeille mahdollisimman laajan asiakasjoukon. Suomessa usein käyvät ostosmatkailijat suosivat yleensä Invoicea täysimääräisen veronpalautuksen vuoksi. Palautusliikkeet taas veloittavat asiakkaalle maksettavasta veronpalautuksesta oman palvelumaksunsa. Suomessa harvemmin vieraileville taas palautusliikkeiden palvelut ovat edullisempia, sillä veronpalautukset saa rajalta maasta poistuttaessa, eikä tarvitse palata samaan liikkeeseen puolen vuoden sisällä. Palautusliikkeiden etuna Invoiceen nähden on myös asioinnin vaivattomuus, sillä eri liikkeissä asioivat ostosmatkailijat saavat kaikista matkalla tekemistään ostoksista arvonlisäveronpalautuksensa yhdestä paikasta sen sijaan, että kävisivät hakemassa ne joka liikkeestä erikseen.

ATTITUDES TOWARD RUSSIAN CUSTOMERS IN THE FINNISH RETAIL TRADE SECTOR – A salesperson’s point of view

The amount of Russian tourists in Finland has increased significantly in the past years. The impact of Russian tourism to the Finnish retail trade sector is enormous, since Russian tourists often spend a lot of money particularly on shopping. Shopping tourism is mainly focused in the near border cities, such as Imatra and Lappeenranta, and in addition in Helsinki metropolitan area. The purpose of this study is to map the attitudes and perceptions of the sales personnel who are working in the Finnish retail trade sector towards Russian customers and to discover which elements affect these attitudes. The theories in this study are based on cultural elements and elements related to sales behavior and performance. Cultural differences between Finland and Russia, cultural distance and cultural intelligence form the cultural aspect of this study. Customer orientation vs. sales orientation (SOCO), adaptive selling, selling skills and job competency, salesperson’s affect and empathy toward customers, and job autonomy form the elements concerning sales behavior and performance. Furthermore, the attitude – behavior link, based on social psychology is addressed. A survey was conducted in two retail trade chains operating in Finland. These retail companies have stores and department stores in different geographical areas in Finland and the survey was conducted in altogether 19 cities. In addition to the theories that were discussed, two expert interviews were conducted in order to get a deeper understanding of the phenomenon at hand. Moreover the interviews helped in the formulation of the hypotheses and the questionnaire design. The questionnaires were sent directly to the stores, where they were placed so that they were available for the sales personnel. Altogether 487 usable responses were collected. The returned questionnaires were analyzed with IBM SPSS 21 statistics program. The results of this study indicated that the attitudes toward Russian customers are more negative compared to other foreign customers. However, the respondents’ attitudes toward and perceptions of Russian customers varied a lot. From the background variables age, education level, length of employment in current workplace, and length of experience in customer service had an effect on the attitudes of the respondents. In addition, the perceptions of Russian customers were more positive in the Eastern Finland compared to Helsinki metropolitan area. The cultural elements; cultural knowledge, cultural distance and cultural intelligence all affected the attitudes of the respondents. From the elements related to sales behavior and performance customer orientation, salesperson’s affect and empathy toward customers, and perceived job autonomy had an effect on the attitudes

Esimiestoiminnan vaikutukset lyhytaikaisiin sairauspoissaoloihin

Yrityksissä on viimeisten vuosien aikana alettu keskustella enemmän sairauspoissaoloista. Ne muodostavat monissa yrityksissä merkittävän kuluerän. Monissa yrityksissä joudutaan käsittelemään sairauspoissaoloja jollakin tavalla. Jokaisella yrityksellä on olemassa toimintatapoja lyhytaikaisten sairauspoissaolojen vähentämiseksi. Toimintatavoilla on tarkoitus tukea esimiehiä käsittelemään työntekijöiden poissaoloja. Työntekijöiden sairauspoissaolot, työkykyyn ja työstä suoriutumiseen liittyvät asiat ovat helpompia käsitellä toimintamallien avulla. Esimiestoiminnalla on todettu olevan yhteys lyhytaikaisiin sairauspoissaoloihin. On lyhytaikaisia sairauspoissaoloja esimiehistä riippumattomistakin syistä, mutta niiden esiintyessä usein, saattaa taustalla olla jokin muu tekijä kuin sairaus. Tämän tutkimuksen avulla oli selvittää eniten lyhytaikaisia sairauspoissaolojen omaavien myymälöiden työtyytyväisyyttä ja onko esimiestoiminnalla selkeä yhteys poissaoloihin. Yrityksellä on käytössään erilaisia toimintamalleja lyhytaikaisiin poissaoloihin ja niiden vähentämiseen. Tutkimuksen avulla pyrittiin huomaamaan onko jokaisessa myymälässä samat toimintamallit.

Hugh Alexander Papers, 1811-1816 [photocopy]

Hugh Alexander, b. 1780 arrived in Niagara shortly after his birth. He attended school and later apprenticed as a clerk. In 1797 he was granted 200 acres of land in Bertie township and became a merchant and trader in Fort Erie. He was the owner of a sailing vessel, the Chippawa, which he used to transport goods in the area. The ship was lost and/or confiscated as a result of War of 1812 skirmishes on Lake Erie. By 1812 Hugh Alexander was in business together with his brother Ephraim. The Alexander’s storehouse, store and house were burned by the British military when they abandoned Fort Erie ahead of the invading American military in late May 1813. At the time of the burning, Hugh Alexander was engaged as a Lieutenant with the 3rd Lincoln Militia. Prior to this Hugh Alexander had established a second mercantile in Stamford, opposite the green. Misfortune was to strike at this location as well when the British military abandoned the whole of the Niagara area to the invading American forces and the Stamford location was looted. After the end of the hostilities Alexander went on to rebuild his storehouse in Fort Erie and to re-establish his store in Stamford. Hugh Alexander died on November 2, 1817 and is buried in the Stamford Presbyterian Cemetery. Source: George A. Seibel, The Niagara Portage Road: 200 Years 1790-1990.

Materials related to military and naval operations of the 1812 era, research of the late Robert Malcomson, Canadian author and historian. Materials include photocopies of materials relating to the War of 1812, photographs and detailed research notes Malcomson made regarding his approach to research (mainly found in Series VIII). Materials were originally arranged in binders relating to an area of research or a certain publication. Articles were removed from the binders and placed in folders using original titles from the binders as series or sub-series titles. Articles within the binders were separated by tabs indicating what the article related to in the publication or topic of interest. In order to avoid repetition, the writing on the tab was used for folder titles, as each folder would be a part of the Series under which it was grouped. The tab names could be authors, events, accounts etc. of the War. Series and sub-series titles were derived from the original titles on the binders. Original intellectual order was retained, grouping similar subjects into Series and Sub-series. Dates recorded were the publication dates of the articles; however, if no publication date was present the date of retrieval was used if from an academic database (ex. JSTOR). The black and white photos from various repositories are reproductions of paintings, microfilm etc. on photographic paper. The colour photographs from various repositories are actual photographs. All books donated by Malcomson were integrated into the University’s Special Collections book collection. These volumes are noted at the end of the finding aid under separated materials.
