Näin KRP tutkii Vastaamo-rikoksia tietopyynnöillä jokainen vastaus vie lähemmäs kiristäjää

www.is.fi/digitoday/tietoturva/art-2000007865666.html ITSE tietomurron ja kiristyksen suhteen auki ovat samat tutkintalinjat kuin aikaisemminkin, kertoo sanoo KRP:n rikoskomisario Marko Leponen. Niissä yritetään selvittää tietomurtojen tekijän ja kiristäjän henkilöllisyyttä ja sitä, onko kyseessä sama taho. – Nyt kammataan aineistoa tiheällä kammalla, ja se on hidasta. Se johdattaa meitä kuitenkin koko ajan eteenpäin ja kertoo, mitä meidän pitää tutkia seuraavaksi. Jokainen löydös kuljettaa askeleen eteenpäin ja tätä polkua kuljemme sinne, missä oletamme epäillyn tai epäiltyjen olevan. Emme etsi aineistoa summittain, Leponen sanoo.

yrityksille.elisa.fi/ideat/zero-trust-nollaluottamus-turvaa-ict-ymparistosi/ Zero Trust eli “luottamattomuuden periaate” on kehitetty modernien ja ketterästi kehittyvien ICT-ympäristöjen suunnitteluun. Se auttaa rakentamaan tietoturvaa nykypäivän monimutkaisessa maailmassa, jossa eri ICT-järjestelmät integroituvat toisiinsa. Zero Trust -mallin perustana on nimensä mukaisesti, että luottamus on nolla kaikilla ajan hetkillä. Laitteet ja käyttäjät tunnistetaan kaikissa tilanteissa ja päätös pääsyn sallimisesta perustuu riskiarvioon. Vahvan tunnistautumisen käyttö on yksi perusasioita.

To Patch or Not to Patch in OT That Is the Real Challenge

www.tripwire.com/state-of-security/ics-security/to-patch-or-not-to-patch-in-ot-that-is-the-real-challenge/ What do you think of when your mind goes to an OT environment? Is it all about old legacy machines and some specialized devices such as Programmable Logic Controllers (PLC), Servos, Variable Frequency Drives (VFD), RTUs and other remote IO devices?. If so, you are almost right. But also remember there is a fair number of IT like assets in that environment, too. As a result, patching in the OT environment is not altogether a wrong or far-fetched notion. It’s just not a blanket one.

Defenders, Know Your Operating System Like Attackers Do!

isc.sans.edu/forums/diary/Defenders+Know+Your+Operating+System+Like+Attackers+Do/27212/ Not a technical diary today but more a reflection When I’m teaching FOR610[1], I always remind students to “RTFM” or “Read the F Manual”.
