Hacking Closed Networks
When the USS John McCain collided with a freighter, there was speculation that the ship was hacked, but officials quickly stated it was impossible because the ship’s network was closed. That is not true. Stuxnet is one of many examples where attackers breached closed networks. This presentation will cover many ways closed networks can be compromised with examples, and how to prevent such attacks.
Learning Objectives:
1: Overcome the myth that closed networks can’t be hacked.
2: Identify vulnerabilities allowing access to closed networks.
3: Learn how to counter the vulnerabilities allowing compromise of closed networks.

Framework for wireless network security using quantum cryptography
Data that is transient over an unsecured wireless network is always susceptible to being intercepted by
anyone within the range of the wireless signal. Hence providing secure communication to keep the user’s
information and devices safe when connected wirelessly has become one of the major concerns. Quantum cryptography provides a solution towards absolute communication security over the network by encoding
information as polarized photons, which can be sent through the air. This paper explores on the aspect of
application of quantum cryptography in wireless networks.
In this paper we present a methodology for integrating quantum cryptography and security of IEEE 802.11 wireless networks in terms of distribution of the encryption keys.

CERTIFICATELESS SCHEME BASED NTRU CRYPTOSYSTEM FOR AD-HOC UWB-IR NETWORK
From the radar and military research world’s, the Ultra-WideBand Impulse Radio (UWB-IR) was
adopted in the telecommunications world in the 1990’. Currently, the UWB-IR technology is an
interesting candidate for close range Wireless Sensors Networks (WSNs). It is particularly attractive
for industrial sensor networks due to its resilience to multipath interference, simple transceiver
circuitry, accurate ranging ability, and low transmission power. In order to secure data and communications
in the Ad-Hoc UWB-IR networks, UWB-IR requires suitable encryption protocols. In
this paper, we review and summarize the IEEE 802.15.4 security sub-layer protocol of UWB-IR
based Symmetric Key Cryptography scheme. Then, we highlight the different vulnerabilities and
weaknesses present in this type of scheme. Finally, we prove, after a deep examination of multiple
Public Key Cryptography (PKC) schemes, that the certificateless one is the most suitable for Ad-Hoc
UWB-IR networks characterized by nodes mobility. Indeed, we have also evaluated and analyzed the
different public key cryptosystems (PKCS) and concluded that NTRU is the most optimum public
key cryptosystem to be used with the certificateless scheme in order to secure data and communications
in Ad-Hoc UWB-IR Networks. This is due to the fact that it is the fastest PKCS to provide
different security levels at a high speed with very constrained resources.
Mobile computing notes and material
Here are the key points about guided and unguided transmission:
- Guided transmission uses physical media like wires and fiber optics to transmit signals along a directed path from transmitter to receiver. It allows for high-quality transmission but limits mobility.
- Unguided or wireless transmission converts signals to electromagnetic waves that can transmit through open space. It allows mobility as devices can communicate anywhere within range of a cell tower or access point. However, wireless signals can be interrupted by interference.
- Mobile communication involves transmission of data to/from handheld devices, with at least one being mobile. It uses wireless networks for mobility as users move around.

This document summarizes a research paper that classifies different types of networks and discusses their associated security issues. It categorizes networks based on size (LAN, MAN, WAN), design (peer-to-peer, client-server, standalone), layering (layered, non-layered), and provides examples such as Ethernet, Wi-Fi, VPNs. It also discusses common security threats for different network types like viruses, denial of service attacks, and evaluates security measures including encryption, firewalls, access control. The paper aims to provide a comprehensive classification of networks and analyze how security needs vary depending on the network and software development stages.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
