Direct broadcasting satellite services allow for communication between stations that are too far for conventional means. One station uplinks a signal to a satellite, which converts and downlinks the signal to the second station. Direct broadcast satellites (DBS) transmit directly from the transmitter to users, who receive signals from geostationary satellites in digital format. DBS provides satellite television and radio services with small receiving dishes, broadcasting hundreds of channels using video compression over the available bandwidth.

Satellite communications
This document discusses how satellite communications works. Satellites act as relay stations, receiving uplinks from one earth station and sending the signal back down as a downlink to another earth station. This allows stations too far for conventional communication to connect. Satellites provide advantages like global coverage independent of distance and precise satellite-to-satellite communication. Launching satellites is costly, bandwidth is limited, and there is propagation delay versus terrestrial networks. Satellites are used for fixed, broadcast and mobile services. They orbit in GEO, LEO, MEO and other orbits, with GEO providing stationary positioning and LEO/MEO requiring satellite networks. Effective satellite communication requires space, ground control and user segments.
Satellite broadcasting
Satellite broadcasting involves transmitting audio and video content via satellite for widespread distribution. Content is uplinked to satellites in geostationary orbit over the equator, which then broadcast the signals to receivers over a large area. Different types of satellite orbits - such as low earth orbit (LEO), medium earth orbit (MEO), and geostationary orbit (GEO) - determine factors like coverage area and signal strength. While satellite broadcasting provides universal coverage and versatility, it also faces disadvantages including high costs of satellite launches and maintenance.

Satellite networks
Satellite communications uses satellites as relay stations to transmit signals between Earth stations that are too far for direct transmission. Signals are sent to the satellite (uplink) and retransmitted to another station (downlink). Satellites provide wide coverage and transmission costs are independent of distance. Orbits include GEO, LEO, MEO and HAPs. Capacity is allocated using FDMA or TDMA, dividing available frequencies or time slots between users.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

#Abstract:
- Learn more about the real-world methods for auditing AWS IAM (Identity and Access Management) as a pentester. So let us proceed with a brief discussion of IAM as well as some typical misconfigurations and their potential exploits in order to reinforce the understanding of IAM security best practices.
- Gain actionable insights into AWS IAM policies and roles, using hands on approach.
#Prerequisites:
- Basic understanding of AWS services and architecture
- Familiarity with cloud security concepts
- Experience using the AWS Management Console or AWS CLI.
- For hands on lab create account on [killercoda.com](https://killercoda.com/cloudsecurity-scenario/)
# Scenario Covered:
- Basics of IAM in AWS
- Implementing IAM Policies with Least Privilege to Manage S3 Bucket
- Objective: Create an S3 bucket with least privilege IAM policy and validate access.
- Steps:
- Create S3 bucket.
- Attach least privilege policy to IAM user.
- Validate access.
- Exploiting IAM PassRole Misconfiguration
-Allows a user to pass a specific IAM role to an AWS service (ec2), typically used for service access delegation. Then exploit PassRole Misconfiguration granting unauthorized access to sensitive resources.
- Objective: Demonstrate how a PassRole misconfiguration can grant unauthorized access.
- Steps:
- Allow user to pass IAM role to EC2.
- Exploit misconfiguration for unauthorized access.
- Access sensitive resources.
- Exploiting IAM AssumeRole Misconfiguration with Overly Permissive Role
- An overly permissive IAM role configuration can lead to privilege escalation by creating a role with administrative privileges and allow a user to assume this role.
- Objective: Show how overly permissive IAM roles can lead to privilege escalation.
- Steps:
- Create role with administrative privileges.
- Allow user to assume the role.
- Perform administrative actions.
- Differentiation between PassRole vs AssumeRole

Broadcasting sattelite
- 1. Direct broadcasting satellite services Presentators Adan sulub abdille Eng Abdirashid Abdullahi yusuf Mohamed ahmed kaatun Mohamed abdullaahi muse Abbas ahmed Mohamed
- 2. Basic of sattelites Types of sattelites Direct Broadcast satellite OVER VIEW
- 3. • • • • Two stations on Earth want to communicate through radio broadcast but are too far away to use convectional means. The two stations use a satellite as a relay station for their communication. One earth station sends a transmission to the satellite. This is called Uplink. The satellite transponder converts the signal and send it down the second earth station. This is called Downlink. Basics:- how satallites work
- 4. ADVANTAGES OF SATELLITES • The advantage of satellite over terrestrial communication are :- The coverage area of satellite greatly exceeds that of terrestrial system. Transmission cost of satellite is independent of distance from the centre of the coverage area. Satellite to satellite communication is very precise. High bandwidth are available for use.
- 5. • The disadvantages of satellite communication: Launching satellite in to orbit is costly. There is a larger propagation delay in satellite communication than terrestrial communication.
- 6. HOW SATELITTES ARE USED 1. • • • • Service type Fixed Service Satellites(FSS) Example: Point to point communication. Broadcast service satellite Example: satellite television radio Also called Direct Broadcast Service(DBS) Mobile service satellites(MSS) Example: Satellite Phones
- 7. TYPES OF SATELLITES • Satellite orbits GEO LEO MEO Molniya Orbits HAPs
- 8. Direct Broadcast satellite service
- 9. INTRODUCTION • • • Satellite communication means communicating through satellites. Now satellite services have shifted away from telephone, toward video and data delivery, with television broadcasting delivery to the home. We previously used under sea cables for voice communication, but it’s limited bandwidth prevented their use for video signals. Satellites are very effective way to distribute wide band signals
- 10. DIRECT BROADCAST SATELLIES • • • • • Direct Broadcast Satellite is a communication link that transmits directly from transmitter to the user. Direct broadcast satellite (DBS) refers to satellite television (TV) systems in which the subscribers, or end users, receive signals directly from geostationary satellites. Signals are broadcast in digital format at microwave frequencies. DBS is the descendant of direct-to- home (DTH) satellite service The end user receives data from a high frequency satellite in geosynchronous orbit(GEO). The high power transmission from this satellites allows the user’s receiving dish to be the size very small. By using video compression and encoding in the transmission, hundreds of channels can be broadcast over the bandwidth available.
