EAP-TLS uses certificates and PKI for mutual authentication between clients and RADIUS servers, requiring client and server certificates that must be managed. EAP-FAST establishes a secure tunnel using dynamically generated PACs instead of certificates. PEAP provides one-way authentication from server to client using a server certificate, allowing different inner authentication methods like EAP-GTC and EAP-MSCHAPv2 without client certificates. Cisco LEAP authenticates users via a username and password with dynamic WEP keys.
TLS provides confidentiality, identity, and integrity for internet communication. It is used for HTTPS web pages and applications on computers and phones. TLS is based on SSL and uses asymmetric encryption where the server sends a public key to set up the secure connection. The client then challenges the server, which responds using its private key to prove its identity. Certificates bind a public key to an identity and are signed by a Certification Authority. They contain information like the key, owner identity, and validity period.
Windows RT devices can be used in corporate environments if managed properly. Windows RT provides limited management capabilities compared to full Windows devices, but supports application deployment and some policy enforcement through Intune and ConfigMgr. Key challenges include application delivery restrictions, limited VPN configuration options, and lack of remote control and software metering capabilities. Proper infrastructure like Intune, ConfigMgr and VPN servers is required to securely connect and manage Windows RT devices in an enterprise.

Kerberos Security in Distributed SystemsIRJET Journal
Kerberos is a network authentication protocol that provides single sign-on capabilities for client-server applications by allowing nodes communicating over a non-secure network to prove their identity to one another in a secure manner. It uses tickets and secret session keys to authenticate users and services. When a client wants to access a service, Kerberos issues it a ticket-granting ticket which it can use to obtain service tickets from the ticket granting service. These tickets contain encrypted proofs of the client's identity that can be verified by the service. Kerberos supports cross-realm authentication and uses shared symmetric keys and timestamps to securely authenticate users within distributed systems. While effective, it has some limitations such as increased computation load, single point of failure if the

This document discusses human and technological aspects of cyber threats facing universities. It notes that while increased data and connectivity enable opportunities, they also present cybersecurity risks that could threaten an organization's existence. The challenges for IT security leaders are to balance security awareness with business needs. Recent attacks have shown blending of new and old techniques, resulting in highly evasive threats. The document also describes the four key steps in security authentication: identification, authentication, authorization, and accountability. It stresses integrating these steps is vital for securing networks against various attacks.
One obvious side effect of migrating to a microservices architecture is the need for infrastructure automation. Unfortunately, most automation systems do not take security into consideration, making production deployments orders of magnitude more complex than the initial testbed deployment.
The perfect example of this steep increase in deployment difficulty is the creation and management of Public-Key-Infrastructures (PKI). Even though the use of TLS Certificates for service to service communication is known as a best-practice, very few companies actually deploy their systems using mutually-authenticated TLS connections.
In this talk I will go over why TLS is the right solution for service to service communication, describe ways to automate the creation and management of your PKI, and present in detail how Docker's swarm orchestration system bootstraps and manages individual node certificates.

This document discusses network security and the Kerberos authentication protocol. It provides an introduction to Kerberos, describing how it works to allow users and services to authenticate over a network. Kerberos uses secret key cryptography and issues tickets to allow users to securely access remote services without sending passwords over the network in clear text. The document outlines the initialization process when a user requests a ticket-granting ticket from the Kerberos server, and how that ticket is then used to request and access remote services. It also discusses some of the limitations of Kerberos and enhancements being made.

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
