NdFluents: An Ontology for Annotated Statements with Inference PreservationJosé M. Giménez-García
RDF provides the means to publish, link, and consume heterogeneous information on the Web of Data, whereas OWL allows the construction of ontologies and inference of new information that is implicit in the data. Annotating RDF data with additional information, such as provenance, trustworthiness, or temporal validity is becoming more and more important in recent times; however, it is possible to natively represent only binary (or dyadic) relations between entities in RDF and OWL. While there are some approaches to represent metadata on RDF, they lose most of the reasoning power of OWL. In this paper we present an extension of Welty and Fikes' 4dFluents ontology---on associating temporal validity to statements---to any number of dimensions, provide guidelines and design patterns to implement it on actual data, and compare its reasoning power with alternative representations.
The HDF Product Designer – Interoperability in the First MileTed Habermann
Interoperable data have been a long-time goal in many scientific communities. The recent growth in analysis, visualization and mash-up applications that expect data stored in a standardized manner has brought the interoperability issue to the fore. On the other hand, producing interoperable data is often regarded as a sideline task in a typical research team for which resources are not readily available. The HDF Group is developing a software tool aimed at lessening the burden of creating data in standards-compliant, interoperable HDF5 files. The tool, named HDF Product Designer, lowers the threshold needed to design such files by providing a user interface that combines the rich HDF5 feature set with applicable metadata conventions. Users can quickly devise new HDF5 files while at the same time seamlessly incorporating the latest best practices and conventions from their community. That is what the term interoperability in the first mile means: enabling generation of interoperable data in HDF5 files from the onset of their production. The tool also incorporates collaborative features, allowing team approach in the file design, as well as easy transfer of best practices as they are being developed. The current state of the tool and the plans for future development will be presented. Constructive input from interested parties is always welcome.
Hdf Augmentation: Interoperability in the Last MileTed Habermann
Science data files are generally written to serve well-defined purposes for a small science teams. In many cases, the organization of the data and the metadata are designed for custom tools developed and maintained by and for the team. Using these data outside of this context many times involves restructuring, re-documenting, or reformatting the data. This expensive and time-consuming process usually prevents data reuse and thus decreases the total life-cycle value of the data considerably. If the data are unique or critically important to solving a particular problem, they can be modified into a more generally usable form or metadata can be added in order to enable reuse. This augmentation process can be done to enhance data for the intended purpose or for a new purpose, to make the data available to new tools and applications, to make the data more conventional or standard, or to simplify preservation of the data. The HDF Group has addressed augmentation needs in many ways: by adding extra information, by renaming objects or moving them around in the file, by reducing complexity of the organization, and sometimes by hiding data objects that are not understood by specific applications. In some cases these approaches require re-writing the data into new files and in some cases it can be done externally, without affecting the original file. We will describe and compare several examples of each approach.

What is zero trust model of information security?Ahmed Banafa
The Zero Trust Model of information security simplifies how information security is conceptualized by assuming there are no longer “trusted” interfaces, applications, traffic, networks, or users. It takes the old model—“trust but verify”—and inverts it, because recent breaches have proven that when an organization trusts, it doesn’t verify. (Forrester)
There appears to be lot of confusion around what security based certifications should one opt for. Which one is affordable? Will that be worth doing w.r.t career path in security. Will that cost and time devoted be justified on achieving that certification? Is it in tune with the trends in the market?
This presentation will drill down to present a solution based approach in identifying and choosing the right certification track based on your interest area of specialization in information security field. Open discussion will be done on what to do once you have achieved your dream certification.

The Zero Trust Model of Information Security Tripwire
In today’s IT threat landscape, the attacker might just as easily be over the cubicle wall as in another country. In the past, organizations have been content to use a trust and verify approach to information security, but that’s not working as threats from malicious insiders represent the most risk to organizations. Listen in as John Kindervag, Forrester Senior Analyst, explains why it’s not working and what you can do to address this IT security shortcoming.
In this webcast, you’ll hear:
Examples of major data breaches that originated from within the organization
Why it’s cheaper to invest in proactive breach prevention—even when the organization hasn’t been breached
What’s broken about the traditional trust and verify model of information security
About a new model for information security that works—the zero-trust model
Immediate and long-term activities to move organizations from the "trust and verify" model to the "verify and never trust" model

Companies and organizations have been following many traditional strategies for deploying WAF (web application firewall) in their infrastructure where most of the work is done. manually. Every ACL, every rule entry, every signature, and every other configuration was created and managed by hand. It could have various flaws: flaw of wrong ACL, flaw of accidental misconfiguration, flaw of bad signature, and other various things. The good news is that thanks to the DevOps Rebel Alliance, we now have a better way to do things: Infrastructure-as-Code (IAC).
Instead of clicking around a web UI or manually executing commands and setting up rules and configuration, the idea behind IAC is to write code to define, provision, and manage your WAF. You can validate each WAF change through code reviews and automated tests and you can create/use a library of reusable, documented, battle-tested code that makes it easier to scale and evolve your WAF. In this talk by Avinash Jain, we will have a quick on the various concept of what, how and why of "Automating AWS WAF using Terraform".
Discussion on traditional threat intelligence model, explore advanced approaches to reduce manual intervention and convert it into actionable threat intelligence.

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.
