Sichere Cloud: Sicherheit in Cloud-Computing-Systemen (Umfrage des Fraunhofer...Sabrina Lamberth-Cocca
Cloud Computing gilt als eine der wichtigsten Innovationen in der (IKT-) Wirtschaft der vergangenen Jahre. Die
Idee ist, dass Speicherplatz, Rechenleistung und konkrete Software-Anwendungen nicht mehr beim Anwender
selbst vorgehalten, sondern extern als Dienstleistung eingekauft werden.
Vielversprechend sind die Möglichkeiten, die sich durch das Outsourcing von Rechen-, Speicher- und ITDienstleistungen
für Unternehmen ergeben. Bevor Unternehmen jedoch in die Wolke ziehen, müssen
grundlegende Fragestellungen geklärt werden; speziell die Frage nach der Sicherheit ist vorrangig.
Aus diesem Grund erforscht das Fraunhofer-Institut für Arbeitswirtschaft und Organisation IAO in Zusammenarbeit
mit der BITKOM, inwiefern Cloud-Anbieter auf die Sicherheitsanforderungen potenzieller Kunden vorbereitet sind.
In diesem Zusammenhang wurden ein Stimmungsbild und konkrete Unternehmensanforderungen erhoben.

Whitepaper über IT-Sicherheit in Industrie 4.0 Projekten der DST consulting Hans Peter Knaust
Die fortschreitende Digitalisierung des Wirtschaftslebens ermöglicht neue Geschäftschancen und Geschäftsmodelle. Dabei verlagert sich der Schwerpunkt der digitalen Transformation zunehmend aus den digitalen Handelsplätzen in die reale Welt.
Die „Digitale Transformation“ und besonders Projekte im Umfeld von Industrie 4.0 fokussieren auf den Datenaustausch und die Realtime-Verarbeitung. Es werden zunehmend große Datenmengen aus Onlinesystemen, Mobile-Anwendungen und technischen Produktionssystemen zusammengeführt und verarbeitet, sodass die sichere Nutzung und Weiterverarbeitung solcher Daten ein wesentlicher Erfolgsfaktor sind.
Sicherheitsrisiken werden aber nicht durch einzelne Schutzmaßnahmen minimiert, sondern durch gestaffelte und sich ergänzende Sicherheitsmaßnahmen begrenzt. Viele Zielbilder sind aufgrund von noch nicht abgestimmten Standards, gesetzlichen Richtlinien und Technologien nicht vollständig definiert und Kunden stehen vor dem Problem, Innovationsfähigkeit und Sicherheit zu verbinden. In dem Whitepaper beschreiben wir konkret drei Maßnahmen, wie die IT-Sicherheit in diesem Umfeld gewährleistet werden kann und wie diese Maßnahmen paßgenau auf die spezifischen Kundenanforderungen angepaßt werden..

The document discusses whether patching control systems is an effective security practice given the challenges of securing industrial control systems. It makes three key points:
1. Patching insecure-by-design devices provides minimal risk reduction since attackers can achieve their goals by exploiting legitimate system features rather than vulnerabilities.
2. Most industrial control systems operate within an insecure-by-design zone, so patching may not prevent attacks since attackers do not need to exploit systems to cause damage.
3. Many control system components have low impact even if compromised, so patching provides little benefit given the effort. Prioritizing patching for systems directly accessible from untrusted networks is recommended over broadly patching everything.

Io t security defense in depth charles li v1 20180425cCharles Li
The document discusses IoT security defense in depth. It notes that early IoT devices from the 1980s lacked many security measures that are now common, like network perimeter defense and endpoint protection. As IoT expands to include more devices, endpoints and attack surfaces, threats have become more aggressive and relentless. Effective IoT security requires an understanding of both IT and OT security practices. The document advocates a defense in depth approach with security controls at multiple layers, including the network, host, application, gateway, controllers and data/devices. Both technical and administrative measures are needed.
The document discusses security fundamentals and classical ciphers. It defines computer and network security, and lists common security problems. It then covers security goals like authentication, access control, confidentiality and integrity. It discusses security services, mechanisms, and attacks. Finally, it provides examples of classical ciphers like the Shift Cipher, Substitution Cipher, Vigenere Cipher, Vernam Cipher, and Transposition Ciphers. It explains how to analyze and break some of these classical ciphers.
Attacking and Defending Autos Via OBD-II from escar AsiaDigital Bond
This document discusses security issues related to accessing and controlling vehicles via OBD-II ports, drawing comparisons to struggles securing industrial control systems. It notes that accessing these systems often means compromising them, as protocols were designed without security. While an analysis of a Progressive Snapshot dongle found no security precautions, lessons from securing critical infrastructure suggest restricting access and implementing least privilege. The document advocates learning from past ICS mistakes to develop secure vehicle protocols and modules.

HijackLoader Evolution: Interactive Process HollowingDonato Onofri
CrowdStrike researchers have identified a HijackLoader (aka IDAT Loader) sample that employs sophisticated evasion techniques to enhance the complexity of the threat. HijackLoader, an increasingly popular tool among adversaries for deploying additional payloads and tooling, continues to evolve as its developers experiment and enhance its capabilities.
In their analysis of a recent HijackLoader sample, CrowdStrike researchers discovered new techniques designed to increase the defense evasion capabilities of the loader. The malware developer used a standard process hollowing technique coupled with an additional trigger that was activated by the parent process writing to a pipe. This new approach, called "Interactive Process Hollowing", has the potential to make defense evasion stealthier.
