The Data Distribution Service for Real-Time Systems (DDS) is an Object Management Group (OMG) standard for publish/subscribe designed to address the needs of a large class of mission- and business-critical distributed real-time systems and system of systems. The DDS standard was formally adopted in 2004 and in less than five years from its inception has experienced swift adoption in a wide variety of application domains. These application domains are characterized by the need to distribute high volumes of data with predictable low latencies, such as, Radar Processors, Flying and Land Drones, Combat Management Systems, Air Traffic Management, High Performance Telemetry, Large Scale Supervisory Systems, and Automated Stocks and Options Trading. Along with wide commercial adoption, the DDS Standard has been recommended and mandated as the technology for real-time data distribution by key administrations worldwide such as the US Navy, the DoD Information-Technology Standards Registry (DISR), the UK MoD, and EUROCONTROL.

Chapter 8: Common Forensic Tools
Overview
In this chapter, you'll learn more about:
· Explore disk imaging tools, forensic software tool sets, and miscellaneous software tools
· Understand computer forensic hardware
· Assemble your forensic tool kit
The first steps in any investigation nearly always involve old-fashioned detective work. As a forensic investigator, you need to observe and record your observations first. Once you start examining media contents, you'll need some tools to help you find and make sense of stored data.
Forensic investigators and computer examiners need several different types of tools to identify and acquire computer evidence. Some evidence is hidden from the casual observer and requires specialized tools to find and access. In this chapter, we'll examine a sampling of some common and popular tools available to carry out computer forensic tasks.
Disk Imaging and Validation Tools
After identifying the physical media that they suspect contains evidence, forensic investigators must make sure media is preserved before any further steps are taken. Preserving the media is necessary to provide assurance the evidence acquired is valid.
Chapter 3, "Computer Evidence," and Chapter 4, "Common Tasks," both emphasize the importance of copying all media first and then analyzing the copy. It's usually best to create an exact image of the media and verify that it matches the original before continuing the investigation. It's rare to examine the original evidence for any investigation that might end up in court. For other types of investigations, however, forensic investigators might perform a targeted examination on the original evidence. For example, assume the job is to examine a user's home folder on a server for suspected inappropriate material. It might be impossible or extremely difficult to create a mirror image of the disk drive, but the disk can be scanned for existing or deleted files while it is in use. Although examining media while in use might not always be the best practice, informal investigations use this technique frequently.
To Copy or Not to Copy?
Whenever possible, create a duplicate of the original evidence, verify the copy, and then examine the copy. Always invest the time and effort to copy original media for any investigation that might end up in a court of law. If you are sure your investigation will not end up in court, you might decide to analyze the original evidence directly. This is possible and desirable in cases where copying media would cause service interruptions.
Your choice of tools to use depends on several factors, including:
· Operating system(s) supported
Operating system(s) in which the tool runs
File systems the tool supports
· Price
· Functionality
· Personal preference
The following sections list some tools used to create and verify media copies. Some products appear in two places in the chapter. That's because several products play multiple roles. This section lists several products ...

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

number of regional power distribution
centers in the region.
Compromised information systems of
three energy distribution companies in
Ukraine
Ukraine Power Grid Cyber Attack
14. IMPACT:
❏ Blackout in a whole geographic area of Ukraine
❏ More than 50 substations went offline
❏ Service outage to customers
❏ More than 80,000 homes remained without electricity
for a period of 1-6 hours
❏ Telephone lines were attacked preventing customers
from reporting outage
Ukraine Power Grid Cyber Attack
16. ❏ KillDisk overwrote critical system files on operator machines
❏ causing them to crash and become inoperable
❏ KillDisk overwrites the master boot record
❏ the infected computers could not reboot
❏ KillDisk components had to be manually set,but
❏ the attackers used a logic bomb that launched KillDisk
automatically about 90 minutes into the attack
Role of KillDisk in Ukraine Attack
17. KillDisk as a malware
❏ First known use of KillDisk Malware was reported by CERT
Ukraine in November 2015
❏ News media companies were attacked at the time of the
2015 Ukrainian local elections
❏ A large number of video materials and various documents
were destroyed as a result of the attack
18. KillDisk as a ransomware
Lately:
❏ KillDisk disk wiper malware is back with new variants - Killdisk
Ransomware
❏ Targeting Windows and Linux Machines and servers
❏ Data encrypted
❏ Demands for unusually large ransom in Bitcoins
For Linux Systems:
❏ Encryption key is not stored anywhere on disk/server
❏ Even after paying ransom, one might not get decryption key
19. KillDisk as a ransomware
