Tutkielma on luonteeltaan kirjallisuuskatsaus.\r\nInternetin k\u00e4ytt\u00f6 on monipuolistunut voimakkaasti 2000-luvulla, ja sill\u00e4 on yh\u00e4 keskeisempi rooli tietoyhteiskunnan jokap\u00e4iv\u00e4isess\u00e4 viestinn\u00e4ss\u00e4. Inter-net-teknologioiden kehitys on mahdollistanut hyvinkin erilaisten palveluiden tarjoamisen alustariippumattomasti ja ilman yhteensopivuusrajoitteita verkko-palveluina. Verkkopalvelut kiinnostavat rikollisia tahoja, koska usein palvelut sis\u00e4lt\u00e4v\u00e4t henkil\u00f6tietojen lis\u00e4ksi pankki- tai luottokorttitietoja. Turvallisuusuh-kista tarkemmin tarkastellaan verkkopalveluiden kannalta keskeisimpi\u00e4 uhkia.\r\nTietomurtoh\u00e4lyttimi\u00e4, eli tunkeutumisen havainnointij\u00e4rjestelmi\u00e4, voi-daan hy\u00f6dynt\u00e4\u00e4 verkkopalveluiden turvallisuuden edist\u00e4misess\u00e4. J\u00e4rjestelmien taustalla on ajatus normaalista poikkeavan k\u00e4yt\u00f6ksen havaitsemisesta j\u00e4rjestel-m\u00e4ss\u00e4 ja t\u00e4h\u00e4n k\u00e4yt\u00f6kseen reagoimisesta. Yleisesti tunkeutumisen esto- ja ha-vainnointij\u00e4rjestelm\u00e4t luokitellaan joko is\u00e4nt\u00e4- tai verkkopohjaisiksi sen perus-teella, miten j\u00e4rjestelm\u00e4 on toteutettu. Toisaalta tunkeutumisen esto- ja havain-nointij\u00e4rjestelm\u00e4t voidaan jaotella joko tunnistepohjaisiksi (signature-based) tai poikkeuksien havainnointiin perustuviksi (anomaly-based), niiden k\u00e4ytt\u00e4m\u00e4n tunnistusmetodin perusteella. Tunkeutumisen havainnointi voi olla joko reaali-aikaista, eli valvontaa suoritetaan jatkuvasti samalla kun havainnoitavaa aineis-toa tulee, tai erill\u00e4\u00e4n tapahtuvaa, jolloin valvottava aineisto ker\u00e4t\u00e4\u00e4n ensin ja analysointi tehd\u00e4\u00e4n my\u00f6hemmin.\r\nUseat tutkimukset ovat osoittaneet hyvi\u00e4 tuloksia tunkeutumisen havain-nointitekniikoiden kehityksen suhteen sek\u00e4 n\u00e4iden tekniikoiden soveltamisesta verkkojen ja verkkopalveluiden tietoturvaan. Poikkeuksien havainnointiin pe-rustuva j\u00e4rjestelm\u00e4 on varteenotettava vaihtoehto verkkopalveluiden turvaami-sessa, mutta k\u00e4ytett\u00e4vyys ei ole viel\u00e4 samalla tasolla kuin tunnistepohjaisissa j\u00e4rjestelmiss\u00e4.", "language": "fi", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Seija Paananen (sepaanan@jyu.fi) on 2012-05-23T04:54:59Z\nNo. of bitstreams: 1\nNiko H\u00e4kkinen.pdf: 362520 bytes, checksum: f1e09528e2eaf286dc099f7a89a164c6 (MD5)", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2012-05-23T04:55:00Z (GMT).
