Overview of Proxy Mobile IP for IPv6 mobility.
Mobile IP (MIP) allows mobile nodes to roam between networks while
keeping existing connections open thus allowing seamless operation
on application level.
However, Mobile IP requires additions to the OS kernel that make deployments
difficult if not impossible alltogether.
Proxy Mobile IPv6 (PMIPv6) allows mobility scenarios for non-MIP aware mobile nodes.
A proxy assumes all functionality required for mobile nodes to roam from
one wireless network to another. PMIPv6 achieves this with a Mobile Access Gateway
(MAG, the proxy) and a Local Mobility Anchor (LMA) that represents the single point of attachment
for corresponding nodes.
PMIPv6 is most suited for campus-type networks where all wireless networks are under
the control of a single authority.
Design and Simulation of Secure Network for University Campusijtsrd
Today's wireless network has come to stay as an essential tool of communication in education sector. These sectors have started deploying computers to perform their daily work such as studying and learning and access resources from their network. This technology has enabled to learn much faster and more conveniently. There are some problems still faced by the users such as poor network design by having large broadcast within the network and various security attacks. These problems can be solved by implementing VLAN Virtual Local Area Network , PS Port Security in switches and ACL Access Control List . They have been simulated in packet tracer 6.3 software.

An open, unencrypted wireless network can 'sniff' or capture and record the traffic, gain unauthorized access to internal network resources as well as to the internet, and then use the information and resources to perform disruptive or illegal acts.Many laptop computers have wireless cards pre-installed. The ability to enter a network while mobile has great benefits. However, wireless networking is prone to some security. Wireless networks relatively easy to break into, and even use wireless technology to hack into wired networks.The risks to users of wireless technology have increased as the service has become more popular.As a result, it is very important that enterprises define effective wireless security policies that guard against unauthorized access to important resources.
Wireless networks are accessible to anyone within the router’s transmission radius. This makes them vulnerable to attacks. Hotspots are available in public places such as airports, restaurants, parks, etc.
In this module, we will introduce you to common techniques used to exploit weaknesses in wireless network security implementations. We will also look at some of the countermeasures you can put in place to protect against such attacks.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

7. Wireless users on a network complain about poor performance within a small
area of a room. Moving away from this area in any direction improves performance
dramatically. What is the first step in designing a solution to this problem?
This might be RF channel overlap, so the technician should verify the channels in use on
each wireless access point and change to non-overlapping channels.
The RF power settings might be set too low on the wireless access points servicing the
room. Increase the RF output power on all wireless access points.
Install a new wireless access point in this center area to provide coverage.
Verify that the wireless access points have sufficient in-line power and connectivity to
the wired network.
8. Which two statements characterize wireless network security? (Choose two.)
