Tunneling provides a mechanism to transport packets of one protocol within another protocol. The
protocol that is carried is called as the passenger protocol, and the protocol that is used for carrying the
passenger protocol is called as the transport protocol. Generic Routing Encapsulation (GRE) is one of the
available tunneling mechanisms which uses IP as the transport protocol and can be used for carrying
many different passenger protocols. The tunnels behave as virtual point-to-point links that have two
endpoints identified by the tunnel source and tunnel destination addresses at each endpoint.
Explains the basics of IPsec: why IPsec, main IPsec protocols (Authentication Header or AH/Encapsulating Security Payload or ESP), modes (tunnel/transport) and ciphers (MD5/AES).
Explains how IPv4 packets are being transformed with IPsec protocols, what are the issues with NAT and what is NAT traversal.
At the very end of the presentation there is a real life example for secure communication between two Linux hosts (using ip xfrm).
IPsec provides the capability to secure communications across a LAN, across private and public WANs, and across the Internet. Examples of its use include:
Secure branch office connectivity over the Internet
Secure remote access over the Internet
Establishing extranet and intranet connectivity with partners
Enhancing electronic commerce security

TCP Intercept was developed to protect servers and other resources from Denial-of-Service (DoS)
attacks, specifically TCP SYN attacks.
Just as the name says, TCP Intercept captures incoming TCP requests. Instead of allowing direct access
to the server, TCP Intercept acts as an intermediary, establishing a connection to the server on behalf of
the requesting client.
TCP Intercept will block a client if too many incoming connections are attempted.
Darkweb + Python: discover, analyze and extract information from hidden servicesJose Manuel Ortega Candel
The talk will start explaining how Tor project can help us to the research and development of tools for online anonymity and privacy of its users while surfing the Internet, by establishing virtual circuits between the different nodes that make up the Tor network. In addition, we will review how Tor works from anonymity point of view, preventing websites from tracking you. Python help us to automate the process to search an discover hidden services thanks to packages like requests,requesocks and sockspy,At this point we will review the crawling process and show tools in python ecosystem available for this task(https://github.com/jmortega/python_dark_web)
These could be the talking points:
-Introduction to Tor project and hidden services
-Discovering hidden services.
-Modules and packages we can use in python for connecting with Tor network
-Tools that allow search hidden services and atomate the crawling process in Tor network

For the first time I am here to cover all CCNA tracis in this Cisco CCNA Certification Exams presentation using the attractive ways.
For those who are not familiar with cisco ccna tracks can find all information about all Cisco CCNA tracks and there exams. I've also covered preparation resources for every exam.
We have covered the following Topics in this Presentation:
CCDA
CCNA Routing and Switching
CCNA Data Center
CCNA Security
CCNA Service Provider
CCNA Video
CCNA Voice
CCNA Wireless
SYMANTEC ENDPOINT PROTECTION Interfacing the SEPM with Protection CenterDsunte Wilson
Protection Center lets you manage Symantec Endpoint Protection together with other Symantec products in a single environment. Symantec Endpoint Protection is integrated with Protection Center by means of a series of Web services.
These Web services provide communication between the Symantec Endpoint Protection Manager server and the Protection Center server.
This study guide is intended to provide those pursuing the CCNA certification with a framework of what concepts need to be studied. This is not a comprehensive document containing all the secrets of the CCNA, nor is it a “braindump” of questions and answers.
I sincerely hope that this document provides some assistance and clarity in your studies.
This tutorial gives very good understanding on Computer Networks After completing this tutorial,You will find yourself at a moderate level of expertise in knowing Advance Networking(CCNA), from where you can take yourself to next levels.
Now more than ever, today’s businesses require reliable network connectivity and access to corporate resources. Connections to and from business units, vendors and SOHOs are all equally important to keep the continuity when needed. Business runs all day, every day and even in off hours. Most companies run operations around the clock, seven days a week so it’s important to realize that to keep a solid business continuity strategy, redundancy technologies should be considered and/or implemented.
So, we need to keep things up and available all the time. This is sometimes referred to five nines (99.999) uptime. The small percentage of downtime is accounted for unforeseen incidents, or ‘scheduled maintenance’ and usually set to take place during times of least impact, like in the middle of the night, or on holiday weekends if planned. If this is not a part of your systems and network architecture it should be considered if you want to keep a high level of availability. Because things break and unforeseen events do take place, we need to evaluate the need for creating an architecture that is ‘highly available’, or up as much as possible, with failures foreseen ahead of time and the only downtime, is to do planned maintenance.
Overview of VPN protocols.
VPNs (Virtual Private Networks) are often viewed from the perspective of security with the goal of providing authentication and confidentiality.
However, the primary purpose of VPNs is to connect 2 topologically separated private networks over a public network (typically the Internet).
VPNs basically hook a network logically into another network so that both appear as one private local network.
Security is a possible add-on to VPNs. In many cases it makes perfectly sense to secure the VPNs communication over the unsecure public network.
VPN protocols typically employ a tunnel where data packets of the local network are encapsulated in an outer protocol for transmission over the public network.
The most important VPN protocols are IPSec, PPTP and L2TP. In recent years SSL/TLS based VPNs such as OpenVPN have gained widespread adoption.

Model Attribute Check Company Auto PropertyCeline George
In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
