AI/ML for Real-time decision-making in IT/OT
Tarne Fidler's presentation discusses implementing AI and machine learning to support real-time monitoring and decision making for IT and OT systems. Critical industrial systems are becoming more difficult to secure as connectivity increases and threats rise. AI is needed to continuously learn without maintenance, determine what is normal behavior to detect compromise, and correlate events to reduce alerts. As OT and IT networks connect more, a common security platform is important to encourage skill sharing and reduce team silos. Thousands of unknown threats are caught every day across unusual network connections, inbound remote access, internal reconnaissance, PLC malfunctions, and hacked IoT devices.
Steganography - Muheeb Ghallab
Steganography is the practice of hiding secret data within ordinary files like images, audio, or video. It works by embedding messages in parts of the digital files that are ignored or discarded by compression algorithms. Common uses include governments hiding sensitive data, digital watermarking for businesses, and individuals secretly communicating. Steganography tools hide messages in files while steganalysis tools try to detect and decode any hidden data. When combined with cryptography, steganography provides better protection of secret communications than either method alone.
Cyber security report in m asteral
Cyber security involves protecting computers, servers, networks, and data from malicious attacks. It covers major areas like application security, information security, disaster recovery, and network security. Cyber threats take various forms like malware, ransomware, phishing, and application attacks. The core goal of cyber security is to ensure business continuity by preventing and reducing the impact of security incidents. Threats can be physical, accidental, from unauthorized access, or malicious misuse. Historically, organizations took a reactive approach to cyber threats but news of data breaches shows this method is ineffective, so a proactive approach with integrated security technologies is needed instead.

Cybersecurity involves protecting computers, servers, networks, and data from malicious attacks. There are several categories of cybersecurity including protecting critical infrastructure, applications, networks, IoT devices, and defending against denial of service and man-in-the-middle attacks. Critical infrastructure security focuses on protecting systems necessary for national security, the economy, and public health and safety. Network security establishes rules and configurations to protect network integrity, confidentiality, and accessibility from evolving cyber threats.
Survey of different Web Application Attacks & Its Preventive Measures
This document summarizes different types of web application attacks and proposed preventative measures. It discusses denial of service (DOS) attacks, cross-site scripting (XSS) attacks, SQL injection attacks, and request encoding attacks that have occurred from 2012-2014. Statistics on the financial impact of these attacks on various industries are provided. The document then proposes solutions to prevent DOS attacks, XSS attacks, SQL injection attacks, and request encoding attacks. These include implementing input validation, output encoding, access control, and encryption. Overall, the document aims to survey common web application attacks and identify best practices for building secure applications.
Digital danger zone tackling cyber security
The protection of critical national infrastructure has long been a serious concern to governments in this region, but an all-encompassing approach means achieving this is no longer limited to physical security. The widespread use of interconnected networks and control systems in national oil, gas, power, water and electricity sectors, means there is now a very real and growing need to enhance cyber security, highlighted by an ever increasing number of international attacks.
Indeed, as a region responsible for much of the world’s energy, GCC countries are placing cyber defence as one of their priority areas for development. Saudi Arabia has plans to spend $3.3Bn on oil and gas infrastructure security and Qatar, Oman, Kuwait and the UAE are set to follow suit over the coming years.
“The cyber security threat to energy installations is surprisingly widespread, running across utilities and distribution networks to generation, refining, and even drilling and exploration. Most security professionals now say that if you think you have not had your security breached then you just haven’t detected it,” says Professor Paul Dorey, director at CSO Confidential.

Digital danger zone tackling cyber security
The document discusses cyber security threats to critical infrastructure in the oil, gas and energy sectors. It notes that governments in the Middle East are prioritizing cyber defense given their responsibility for much of the world's energy and interconnected control systems. Experts warn that cyber attacks are increasingly sophisticated and that utilities and infrastructure face threats from state actors, organized crime groups and hacktivists seeking disruption, espionage or financial gain. Stuxnet demonstrated that attacks can damage public safety, economies and the environment. Countries are working to regulate security and cooperate internationally to address evolving cyber threats.
Cyber Threat to Public Safety Communications
This document discusses cyber threats to public safety communications systems. It begins by describing how communications broke down for first responders during the 9/11 attacks due to overloaded cell networks and damaged radio systems. Since then, improvements have focused on redundancy and interoperability through increased connectivity, but this also introduces more vulnerabilities. The document outlines several cyberattacks against 911 call centers and public safety networks in recent years. It identifies the most attractive targets as the public's access to 911 and single points of failure in interconnected systems. The main security challenges are complacency about risks and limited budgets to address vulnerabilities.
Cyber Threat to Public Safety Communications
This document discusses cyber threats to public safety communications systems. It summarizes that since 9/11, increased connectivity and interoperability between systems has created more potential access points for cyber attacks. Specific vulnerabilities discussed include next generation 911 systems relying on IP networks, reliance on cellular networks using LTE and VOIP, and a shortage of cybersecurity professionals. Potential solutions proposed include using fusion center networks to communicate crisis information over separate internet-based systems rather than agency networks.
Cyber Security – Indian Perspective.pptx
National security is threatened in the realm of cyber security. Critical infrastructure such as power grids and financial systems have become dependent on information technology, making them vulnerable to cyber attacks. As technology becomes more complex and interconnected, security challenges will mount for both providers and consumers. Sophisticated criminal organizations now carry out organized cyber attacks using advanced techniques, blurring the line between legal and illegal activities. Signs indicate that intelligence agencies are developing new ways to conduct espionage over the internet, which has become a weapon for political, military, and economic espionage. Traditional protective measures are not enough to defend against highly coordinated attacks targeting networks with less sophisticated monitoring and defenses.
Volume2 chapter1 security
Preparing today for tomorrow’s threats.
When companies hear the word “security,” what concepts come to mind
— safety, protection or perhaps comfort? To the average IT administrator,
security conjures up images of locked-down networks and virus-free devices.
An attacker, state-sponsored agent or hactivist, meanwhile, may view security
as a way to demonstrate expertise by infiltrating and bringing down corporate
or government networks for profit, military goals, political gain — or even fun.
We live in a world in which cybercrime is on the rise. A quick scan of the
timeline of major incidents (See Figure 1, Page 9) shows the increasing
frequency and severity of security breaches — a pattern that is likely
to continue for years to come. Few if any organizations are safe from
cybercriminals, to say nothing of national security. In fact, experts even
exposed authentication and encryption vulnerabilities in the U.S. Federal
Aviation Administration’s new state-of-the-art multibillion-dollar air
traffic control system
Darktrace_WhitePaper_EnterpriseImmuneSystem
The document discusses a new approach to cybersecurity called the Enterprise Immune System. It is based on advanced machine learning and mathematics to detect threats within an organization's networks. Like the human immune system, it learns what normal activity looks like and can detect subtle anomalies that may indicate threats. This allows organizations to protect themselves while still enabling collaboration and connectivity. The system is based on novel probabilistic mathematics that continuously learns and adapts to changing environments in real time.

One of the most Costliest is data security. Where value addition might be very low but huge investment is required to safeguard it. Data security needs updates of malwares and infringment policies.
In this information era, Security has become more difficult to define and enforce.
information security was limited to controlling physical access to oral or written communications. The importance of information security led societies to develop innovative ways of protecting their information. Recent innovations in information technology, like the Internet, have made it possible to send vast quantities of data across the globe with ease. However, the challenge of controlling and protecting that information has grown exponentially now that data can be easily transmitted, stored, copied, manipulated, and destroyed.
Within a large organization information technology generally refers to laptop and desktop computers, servers, routers, and switches that form a computer network, although information technology also includes fax machines, phone and voice mail systems, cellular phones, and other electronic systems. A growing reliance on computers to work and communicate has made the control of computer networks an important part of information security. Unauthorized access to paper documents or phone conversations is still an information security concern, but the real challenge has become protecting the security of computer networks, especially when they are connected to the Internet. Most large organizations have their own local computer network, or intranet, that links their computers together to share resources and support the communications of employees and others with a legitimate need for access. Almost all of these networks are connected to the Internet and allow employees to go “online.”

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
"$10 thousand per minute of downtime: architecture, queues, streaming and fin...
Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

John Yessis - Telecom and Security
- 1. John Yessis - Telecom and Security
- 2. John Yessis The telecommunications industry is one that has fallen under the spectrum of security threats. It is a challenging environment that has seen state-sponsored activity, activist-based attacks, widespread malware, and a constant and evolving array of threats. Thanks to a constant stream of stories about computer breaches, most people are aware of the kind of threats that affect computer networks.
- 3. John Yessis Such breaches inevitably reach public channels and have made big news. Security threats over time have evolved from early and obvious targets such as financial institutions to the purpose-driven breaches of today. Hackers have a way of finding the softest perceived target because the efforts to attack financial targets are too great in comparison to those targets that have not endured as long of a history of threat. The telecom industry is one that is intertwined with infrastructure, utilities, and the networking industries. One of the greatest threats in the country today is the posture of our critical utilities in the face of constant threats. There is repeated talk that centers on the readiness to contend with security matters in these environments.
- 4. John Yessis Our power grid and its various distribution points are woefully outdated in many ways. The systems that control and manage them were instituted in a time when there was little consideration of these kinds of threats. The cost to innovate and replace some of the systems is significant, but there is hope that new approaches and robust security products can close the gap. Telecommunications is both a target and a solution when it comes to security threats. Telecommunications networks often form the backbone of controls, secure transmissions, and vital information. While interception of information is a threat that concerns many, there is also a threat of disruption that looms over the heads of many.
- 5. John Yessis The simple fact is that modern hackers have realized the ability to financially impact a target through the disruption of vital services. In some cases, the disruption of communication services can be even more impactful than can be described in financial terms. An extended disruption to the power grid, for example, could affect millions.
- 6. John Yessis John Yessis is a sales director that works at EUS Networks. He has been aware of security in the delivery of his solutions and products for as long as he has been in the industry. One of the things that he shares is that a product needs to have an inherent level of security, but it must also be architected in a way that is resilient and hardened to outside threats. https://en.wikipedia.org/wiki/User:John_Yessis https://www.linkedin.com/pub/john-yessis/46/960/125 https://www.facebook.com/John.Yessis https://www.behance.net/johnyessis https://johnyessis.wordpress.com/ https://www.crunchbase.com/person/john-yessis
