Angelo van der Sijpt - How well do you know your network stack? - Codemotion ...Codemotion
Networking is a core part of computing in the digital world we inhabit. But, how well do you know how it works? Do you understand all the moving parts of the OSI stack inside your computer, and how the network is actually put together? How can this ever work? This guided safari of layers, standards, protocols, and happenstance will bring us close to the copper wire, and up through the layers of CDMA/CD, ARP, routing and HTTP. We will make a few excursions through patchworks that still work forty years later, and cleverly designed mechanisms that show that simplicity is the only way to last.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

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.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Editor's Notes
Hello , It’s Tony Fortunato And Peter Ciuffreda from the Technology Firm In this session we are going to use CurrPorts to do some TCP/UDP port and application analysis Enjoy
Peter: so What is CurrPorts? Tony: It is a TCP/UDP port and application analysis tool used to display and log all currently open connections on your local computer. Peter: Does this application require installation? Tony: Well actually it doesn’t require an install. All you need to do is download it and put it in any folder which you would like to access it from. Peter: In other words it’s a portable app. I could also run it off of a portable storage device such as a USB flash drive. Tony: Yup, that’s right.
Peter: Why would we use CurrPorts? Tony: Like stated before, it is used for TCP/UDP port and application analysis. Peter: So could you use it to discover how many ports an application uses, and estimate how long the ports stay open. Tony: Exactly. We can also use it to kill processes that opened specific ports. Peter: Why would we want to kill a process? Tony: Well, if a process is using too many connections, you can kill it to try and speed up your other connections if needed. Also, if you know that you have a port limitation on connections, we can use CurrPorts to help stay within those limits. CurrPorts can also detect and mark with pink, suspicious ports being used by unknown applications.
Tony: The main window of CurrPorts displays all connections currently open, the Process Name of the application, the port and the IP of both the local and remote machines. Peter: From this screen capture we can see that the processes highlighted in green are the active connections. Tony: As discussed previously, the process highlighted in pink is an unknown application marked as suspicious. In this example we used the application IPERF which caused the suspicious process. Peter: If the active connections are marked in green, and the suspicious in red, then the unmarked processes (meaning the white) must be inactive, or applications that are listening. Tony: That’s right.
Peter: When CurrPorts is started for the first time, all the displayed options are turned on in the options menu. But are they all needed? Tony: Depending on what you are looking for you can change your display preferences. If you only want to see what processes are open or established, it would be a good idea to turn off display listening and display closed.
Peter: Why would we want all display options on? Tony: If you wanted to profile how a specific application uses ports you would want to have all options on. Peter: This would let us know if an application uses ports for listening, and if those ports are different than the ones it uses for active connection. Tony: That’s right.
Peter: From the Options Menu, we can set and change the auto refresh rate of the screen. Tony: The auto refresh rate also affects how often the log is updated. We will get into how to use the logs a bit later. Peter: It looks like we can also disable the auto refresh option. Tony: Disabling the auto refresh option means that the screen won’t refresh itself and your currently used processes will remain, but no new processes will appear and no old processes will disappear. Peter: This could be handy if you want to examine a certain process that appeared. You can always change the refresh rate back when you are done examining. Tony: Note that nowhere on the auto refresh option or on the screen does it inform you of the current refresh rate. The best way to find out what it is set to is to just reset it to your desired rate.
Peter; in this example the red application opened and closed a port within the refresh rate of 2 seconds. Therefore nothing would be displayed. Tony, The green application opened before the first refresh period and closed within the next interval. So you would see this application displayed with its relevant port information.
Tony: A nice feature in CurrPorts is the ability for filtering. Peter: We could use this feature to include or exclude specific processes, ports, or even IP addresses. Tony: The only issue with the filters option is that the syntax’s need to be exact. It is best to follow the examples in the Edit Filter window. You must have your Include or Exclude as the first thing in the syntax. Peter: Note that CurrPorts will not warn you if your syntax isn’t in the right format, it simply won’t work. This can be easily seen because processes or ports show up that shouldn’t.
Tony: Another helpful option is the logging feature which allows you to save a log file of the process that appears in CurrPorts. This is from the time you turn on the Log Changes option under the file menu, until it is turned off. Peter: Logging your files is a nice feature since it allows you to look back through the log in case there was something you missed when you took your eyes off the screen for a few seconds. Tony: We will see an example of a log file a bit later.
Peter: It would be great to see how everything in CurrPorts works. Tony: Lets show an example then of how CurrPorts can be used to examine a bittorrent client called uTorrent. Peter: First off, lets open the uTorrent application to discover what its process name appears as in CurrPorts. Once we get the process name we can create a filter to remove all other processes except uTorrent. Tony: Once the filter is created, we can set an auto refresh value of 2 seconds to see the most current changes. Peter: If you take a look at the main screen you should notice only processes for uTorrent. Tony: It would also be a good idea to create a log file to review later.
Peter: The log files show the date and time processes are added or removed, along with the process name, and both the local and remote IP addresses and the TCP or UDP port number.
Tony: For the sake of comparison lets open both CurrPorts and Wireshark to validate the accuracy of CurrPorts. Peter: We noticed that Wireshark is showing that in this case 2 TCP ports and 7 UDP were opened. Although when looking at the CurrPorts log file we can only see 1 TCP and 2 UDP port connections were established. Tony: The other port connections have not been logged if they happened within the 2 seconds between refreshes. This can make is difficult to capture short-lived connections.
Peter: Even though CurrPorts doesn’t appear to capture connections under 2 seconds it is still a nice application for finding out what ports applications use. Tony: The filtering feature is very powerful for concentrating on specific process, ports, etc, unfortunately you must be exact with your syntax’s in order for the filters to work. Peter: having the log files is also a nice feature to look back on things you may have misses, but it is also dependant on the refresh rate and you may miss some connections. Tony: Despite a few short comings I would still recommend this utility for your network toolbox.
Tony: Hope you enjoyed this tip Peter: Have a good day folks, bye for now.
