PENYELESAIAN SOAL UKK/UPK TAHUN 2018 Paket 3 oleh Walid UmarWalid Umar
The document describes steps to configure a server to provide network services including DHCP, DNS, FTP, Samba file sharing, Apache web server, MySQL, mail server, and SquirrelMail webmail. Key services configured are Bind DNS, ProFTPD FTP, Samba file sharing, Apache web server, Postfix mail server, and SquirrelMail webmail. Network interfaces are configured and services are enabled, configured and tested.
An intrusion prevention system (IPS) like Snort can operate in either inline or flexible response mode. Flexible response mode replicates all inbound traffic to a "mirror port" using a network switch. The IPS analyzes this mirrored traffic and sends RST packets to terminate any connections that match drop rules, allowing it to respond proportionately to threats without blocking the network flow. While inline mode can block attacks faster, flexible response is preferable when latency is too high or the IPS is passive, making its efficiency dependent on CPU and memory resources.

Creating "Secure" PHP applications, Part 2, Server Hardeningarchwisp
The document provides guidance on server hardening techniques. It discusses using netstat to view listening services on a server and using update-rc.d or chkconfig to disable unnecessary services from starting at boot.

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.
