Nessus is a vulnerability scanner created in 1998 that allows users to detect vulnerabilities on Windows, Linux, and Mac systems. It uses a web interface to install, scan systems, and generate reports of identified vulnerabilities. Nessus can manage up to 50,000 hosts with a dual-core 2GHz CPU, 2GB RAM, and 30GB disk space. To use Nessus, users download it, register for an activation code, install it, create an account, and then launch scans on target IP addresses or folders. Scans check systems against policies that define what vulnerabilities to test for, such as external/internal network scans or PCI compliance. Scan results show vulnerabilities present and allow drilling into details.

Introduction To Exploitation & Metasploit
Penetration testing involves evaluating systems or networks using malicious techniques to identify security vulnerabilities. It is done by exploiting vulnerabilities to gain unauthorized access to sensitive information. Common vulnerabilities arise from design errors, poor configuration, and human error. Penetration testing is conducted to secure government data transfers, protect brands, and find vulnerabilities in applications, operating systems, databases, and network equipment. Metasploit is an open-source framework used for hacking applications and operating systems that contains exploits, payloads, and modules. Msfconsole is an interface used to launch attacks and create listeners in Metasploit.

BlueHat v17 || A Lustrum of Malware Network Communication: Evolution and Insi...BlueHat Security Conference
Chaz Lever, Georgia Institute of Technology
Both the operational and academic security communities have used dynamic analysis sandboxes to execute malware samples for roughly a decade. Network information derived from dynamic analysis is frequently used for threat detection, network policy, and incident response. Despite these common and important use cases, the efficacy of the network detection signal derived from such analysis has yet to be studied in depth. This paper seeks to address this gap by analyzing the network communications of 26.8 million samples that were collected over a period of five years.
Using several malware and network datasets, our large-scale study makes three core contributions. (1) We show that dynamic analysis traces should be carefully curated and provide a rigorous methodology that analysts can use to remove potential noise from such traces. (2) We show that Internet miscreants are increasingly using potentially unwanted programs (PUPs) that rely on a surprisingly stable DNS and IP infrastructure. This indicates that the security community is in need of better protections against such threats, and network policies may provide a solid foundation for such protections. (3) Finally, we see that, for the vast majority of malware samples, network traffic provides the earliest indicator of infection—several weeks and often months before the malware sample is discovered. Therefore, network defenders should rely on automated malware analysis to extract indicators of compromise and not to build early detection systems. 2009-08-11 IBM Teach the Teachers (IBM T3), Linux Security Overview

The Dark Side of PowerShell by George Dobrea
PowerShell is now a ‘mandatory-to-use’ tool for IT professionals in order to automate administration of the Windows OS and applications, including Azure and Nano Server. Unfortunately, threat actors have recently taken advantage of this powerful scripting language just because PowerShell it’s already installed on your Windows machines, trusted by Admins and most AntiVirus tools! The session presents the steps that should get you starting on (Ethical) Hacking and Pen Testing with PowerShell and some new techniques like JEA (Just Enough Administration) that a defender can use in order to limit the effectiveness of PowerShell attacks.

Nessus:Nessus is the vunerability scanner.Which is devloped by tenable network security.It is
free of charg fo the personal use.
The following type of vunerabilities are allowed to scan by nessus:
1)Misconfiguration(such as open mail relay)
2)Denial of services against TCP
3)Dictionary attacks
4)Default password,absent passwords orfew common passwords
5)PCI DSS audits
Nessus has two main component one is nessus daemon ,whih is esponsible for scan and other is
nessus client which ctrols the scan and provide the result to client. But nes does not provide the

( Ethical hacking tools ) Information grathring
There are a number of different kinds of tools for collecting information about the thoughts and beliefs that different groups have about your organization.
Security & ethical hacking
This document provides an overview of advanced scanning and exploitation techniques for security testing. It discusses using Nmap to scan for open ports and operating systems. The importance of local IP sweeping to find vulnerable systems on a local network is explained. Netcat is demonstrated as a simple way to create a remote shell on another system. Brief examples of shellcode and exploits that can be delivered through media files like JPGs and MP3s are also provided. The conclusion emphasizes that while this information is shown for educational purposes, actually exploiting systems without permission would be illegal.
Client side exploits
This document discusses client-side exploits and tools used for testing them in a controlled network environment. It covers using Metasploit on Kali Linux to generate and encode a Meterpreter reverse TCP payload, deploying it on a Windows client virtual machine, and using Meterpreter post-exploitation commands to maintain access including disabling antivirus and establishing persistence. The goal is to achieve a low detection payload and compromise the client while evading detection, though the document notes that no method is foolproof and antivirus vendors adapt.
Os Virtualization
This document provides step-by-step instructions for installing Ubuntu in a virtual machine and additional software. It describes creating a new virtual machine, selecting installation options, running the Ubuntu installer, and configuring the operating system. Additional steps explain how to install software packages using apt-get and install a web browser and file manager using .deb and .tar.gz packages respectively. Screenshots confirm the successful installations.
Finalppt metasploit
Metasploit is an open source penetration testing framework that contains tools for scanning systems to identify vulnerabilities, exploits to take advantage of vulnerabilities, and payloads to control systems after exploitation. It provides a simple interface for security professionals to simulate attacks while testing systems and identifying weaknesses. The document discusses Metasploit's history and versions, how it can be used to conduct penetration testing, and key concepts like vulnerabilities, exploits, and payloads.

Maven
Maven is a build automation tool used primarily for Java projects that handles dependencies and builds. It downloads libraries and plug-ins from repositories and manages a local cache. The POM (Project Object Model) XML file contains project configuration information like dependencies, directories, and plugins and is used by Maven to build the project. Maven is useful when projects have many dependencies, dependencies change frequently, or continuous integration, testing, and documentation generation are needed.
Jenkins
Jenkins is an open-source tool for continuous integration that was originally developed as the Hudson project. It allows developers to commit code frequently to a shared repository, where Jenkins will automatically build and test the code. Jenkins is now the leading replacement for Hudson since Oracle stopped maintaining Hudson. It helps teams catch issues early and deliver software more rapidly through continuous integration and deployment.
Jenkins
Jenkins is an open-source automation tool written in Java that enables continuous integration and delivery of software projects. It allows developers to integrate changes to a project continuously by automatically building and testing the software project after each new commit. Jenkins has over 1000 plugins that integrate various testing and deployment tools to support continuous integration and delivery workflows.
Sonar qube
SonarQube is an open-source platform that performs automatic code reviews through static analysis to detect bugs, vulnerabilities, and code smells in over 20 programming languages. It provides reports on code quality metrics like duplicated code, code coverage, complexity, and potential issues. SonarQube requires Java and supports analyzing code written in languages like Java, C#, JavaScript, and Python. The SonarScanner is used to analyze source code and generate reports in SonarQube. Quality Gates in SonarQube define thresholds for metrics that projects must meet, such as having no new blocker issues or code coverage above 80%.
Owasp zap
The document provides information on OWASP ZAP, a free and open source web application security testing tool. It discusses what ZAP is, why it is a good choice for security testing, its key features which include an intercepting proxy, scanners, spiders, and fuzzing. It then describes how to launch and use ZAP, covering its graphical user interface, attacking websites by spidering, scanning and reviewing alerts. Key terms like session and context are also explained. Steps to run a scan are outlined, including crawling the site, creating a session and context, attacking with spider and active scans, and reviewing scan results. Finally, the difference between active and passive scans is summarized.
Sonarlint
SonarLint is a free, open source plugin for Visual Studio, PyCharm, Eclipse and IntelliJ IDEA that helps developers fix code quality issues. It provides instant feedback as developers write code, identifying existing issues and new issues introduced. SonarLint detects issues on-the-fly as code is written and provides rich documentation on issues to help developers understand coding best practices and how to resolve problems.
Shift left
Shift left testing involves moving testing as far left or as early in the development process as possible to find and prevent defects early. This is opposed to traditional testing, which only occurred right before release. Shift left testing improves quality by identifying issues early when they are cheaper to fix. While shift left is often best, shift right testing post-production may also be useful in some cases to further enhance customer experience and ensure proper test coverage and automation. To shift left, organizations can engage stakeholders early, do static testing of requirements and design, and see benefits like increased automation, delivery speed, and satisfaction.
Deployment Strategies
A deployment strategy is a method for upgrading applications without downtime. The blue-green deployment strategy involves running two identical production environments - one live (blue) and one idle (green). When deploying an update, it is deployed to the idle environment, tested, and then traffic is routed to it while the former live environment becomes idle for testing. This allows immediate rollbacks if issues arise by simply routing traffic back to the previously live environment. Benefits include reduced downtime and the ability to rollback quickly to a stable release if problems occur.
DSOMM
The DevSecOps Maturity Model (DSOMM) provides a framework for prioritizing security measures when using DevOps strategies to enhance security. It defines four levels of implementation from basic security practices to advanced deployment at scale. There are four main evaluation criteria: the comprehensiveness of static and dynamic code scans, the frequency of security scans, and the completeness of remediation workflows for security findings.
Devops
DevOps is a software development approach that aims to shorten the systems development life cycle and provide continuous delivery with high software quality. It focuses on collaboration between development and operations teams. Key aspects of DevOps include automation of the software delivery process through tools like Docker and Jenkins, continuous integration and deployment, and monitoring of applications in production. While DevOps can improve speed and collaboration, security challenges arise from development teams prioritizing speed over security and keeping up with the fast pace of changes. Adopting DevSecOps practices like automation, clear security policies, and vulnerability management can help integrate security into the DevOps process.
Shift left
Shift left testing involves moving testing as far left or as early in the development process as possible to find and prevent defects early. This is opposed to traditional testing, which only occurred right before release. Shift left testing improves quality by identifying issues early when they are cheaper to fix. While shift left is often best, shift right testing post-production may also be useful in some cases to enhance customer experience and ensure proper test coverage and automation. To shift left, organizations can engage stakeholders early, do static testing of requirements and design, and see benefits like increased automation, delivery speed, and satisfaction.
Lfi
Local File Inclusion (LFI) vulnerabilities allow an attacker to include files from a web server by manipulating input that is used to include files. For example, a script that includes files based on a page parameter, like script.php?page=index.html, could be exploited by changing the page parameter to try and include files like ../../../../etc/passwd. Successful exploitation can reveal sensitive information like the server's password file. LFI vulnerabilities are common and can often be exploited through PHP wrappers like php://input or php://filter to include files or execute system commands on the server.
Directory traversal
Path traversal attacks aim to access files outside the web root folder by using special character sequences like "../" to traverse directories. These attacks work by exploiting the ability of web servers to follow links containing such sequences to access files anywhere on the file system. Preventing path traversal attacks involves filtering user input to remove special characters, ensuring the web server is configured securely, keeping sensitive files outside the web root, and keeping software updated.
Burp documentation
Burp Intruder is a tool for automating customized attacks against web applications. It modifies HTTP requests systematically and analyzes responses to identify interesting features. Common uses of Intruder include enumerating valid identifiers like usernames, harvesting useful data from responses, and fuzzing for vulnerabilities by submitting test strings and analyzing responses.
7 layer OSI model
The document summarizes the 7 layers of the OSI model:
1) Physical layer handles electrical signals and binary data transmission.
2) Data link layer handles physical addressing and error checking.
3) Network layer handles logical addressing and routing between networks.
4) Transport layer handles protocol selection and reliable/unreliable transmission.
5) Session layer establishes and maintains connections between applications.
6) Presentation layer standardizes data formats and handles encryption.
7) Application layer provides networking services to application programs.
Virtual box
VirtualBox is an open-source virtualization software that allows users to run multiple operating systems on a single computer. It can be used for running different operating systems, testing software under various conditions, troubleshooting, and creating test systems. To use VirtualBox, one must install it, set up a virtual host, and then install their desired operating system within the virtual environment.
Tcp IP OSI
The document discusses two reference models for networking:
The OSI Reference Model defines seven interconnected layers for conceptualizing communications between heterogeneous systems - a physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and application layer.
The TCP/IP Reference Model is a four-layered suite of communication protocols developed by the Department of Defense in the 1960s. The four layers are the host-to-network layer, internet layer, transport layer, and application layer. The internet layer defines protocols like IP, ICMP, and ARP.
Burp repeater
Burp Repeater is a tool that allows manual manipulation and resending of HTTP and WebSocket messages to test for vulnerabilities. It displays requests and responses that can be edited and resent. Each message is opened in its own tab that contains controls to issue requests and navigate message history. Options control Repeater behavior like updating headers and following redirects. Tabs can be renamed, reordered, opened, and closed for easy management of messages.
Burp intruder
Burp Suite is a Java-based penetration testing tool with free and professional editions. It has modules for proxying traffic, spidering websites to map content, scanning for vulnerabilities, intrusion testing with customized attacks, and repeating requests to manually test issues. The proxy module sits as a man-in-the-middle and allows inspecting and modifying traffic between the browser and servers.
Hippa
HIPAA is a federal law that requires the protection of sensitive patient health information. It established national standards to protect patients' medical records and other personal health information from being disclosed without consent or knowledge. The U.S. Department of Health and Human Services issued rules under HIPAA, including the Privacy Rule and Security Rule, which protect health information and set guidelines for how it can be collected, used, and shared. HIPAA gives patients more control over their information and defines penalties for any violations of its standards.

How to Create a More Engaging and Human Online Learning Experience
How to Create a More Engaging and Human Online Learning Experience Wahiba Chair Training & Consulting
Wahiba Chair's Talk at the 2024 Learning Ideas Conference. LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
