Various aspects of booter services, attacks, and ethical issues are also mentioned.
This document discusses DDoS attacks and their evolution from early attacks to current booter services. It aims to teach about the concept of DDoS attacks, how they have evolved over time, the damage they can cause, and their current form through booter services. The document outlines how booters work, how they can be monitored and distinguished based on their attack traffic, and the third parties like payment systems and web hosts that indirectly support their operations. It suggests there are legal and ethical arguments that third parties could take mitigation actions against booters.
This document discusses file sharing and internet piracy. It provides a brief overview of file sharing and its history, considering arguments from both sides of the debate. The author notes that while file sharing may seem harmless, it results in billions lost annually for creative industries. However, others argue that file sharing is justified and ethical. The author aims to analyze both perspectives and provide their own stance on the issue.

It then covers specific IE8 security enhancements like XSS filtering, clickjacking defenses, and SmartScreen filtering. The document also discusses centralized management using Group Policy and customizing IE8 deployment with IEAK. It concludes with recommendations for upgrading users and sites from older IE versions to IE8.
Thamimul Anssari has over 7 years of experience in IT support with skills in Cisco networking, Microsoft platforms, LAN/WAN implementation, and problem solving. He holds a Bachelor's degree in Computer Science and Cisco CCNA certification. His experience includes roles as a technical support engineer providing services like server administration, network implementation and maintenance, firewall configuration, and user support. He has experience working with technologies such as Windows, Linux, Cisco routers and switches, firewalls, and network monitoring tools.
Most of the IoT devices are running a Linux distribution, but without a clear updates and/or security strategy.
In this talk we will go through some of the current problems the IoT devices are facing and tools and strategies we can use today to make the situation a bit better for new devices, while keeping our time to market optimized.
We will show some features in Linux and systemd that can help improving the security of these devices. We will also introduce snaps, a packaging format that helps distribute your application and install it isolated from the underlying system and from other applications; and Ubuntu Core, a small, transactional version of Ubuntu for IoT devices, based on snaps.
The document discusses the issues with Network Address Translation (NAT) and why the author cares about IPv6. It summarizes the key impacts of NAT, including that it prevents devices on the same network from acting as peers, relies on external hosts or relays, and is vulnerable to denial of service attacks and loss of state. The author argues that this goes against the intended peer-to-peer nature of the Internet protocols and that IPv6 removes the fundamental constraints of NAT by allowing nodes to use their own IP addresses and communicate directly.
Proxy servers and firewalls both act as gateways between internal networks and external networks like the internet. Proxy servers improve performance by caching frequently requested content, control bandwidth usage, and filter requests. Firewalls protect internal networks from external threats by packet filtering, analyzing packets, providing proxy services, and logging and alerting administrators of potential threats. Popular proxy software includes Squid, ISA Server, and WinRoute, while popular firewall software includes ISA Server, Cisco PIX, Norton Internet Security, and ZoneAlarm.
The document discusses web servers, proxy servers, server logs, and network security. It provides details about Apache and Squid servers, how they work, and sample logs. It also covers topics like firewalls, IDS/IPS, antivirus software, malware threats, and configuring a VPN to update a university website.

DevSecCon London 2019: How to Secure OpenShift Environments and What Happens ...DevSecCon
Jan Harrie
Security Analyst at ERNW GmbH
OpenShift by Red Hat is one of the major Platform as a Service (PaaS) solutions on the market. It is used to automatically deploy Kubernetes clusters and provides useful extensions for cluster management mixed with some magic under the hood.
Instantiating a Kubernetes cluster is often a crucial step in setting up a modern application stack. But be aware – a lot of configuration parameters are awaiting you. And here several misconfigurations may occur that can lead up to a compromise of the cluster. Privileged containers, tainting of masters and executing workloads on them, missing role-based access controls, and misconfigured Service Accounts are part of the problem.
In this talk, I will explain which configuration parameters of an OpenShift environment are critical to ensure the overall security of the deployed Kubernetes clusters. Implications of misconfigurations will be demonstrated during live demos. Finally, recommendations for a secure configuration are provided.
The document discusses CloudFlare's global network for mitigating DDoS attacks and content delivery. It describes how CloudFlare deploys thousands of servers across 30+ datacenters worldwide and peers with internet exchanges around the globe to distribute traffic. This allows CloudFlare to localize DDoS attacks and continue serving other regions. The document also outlines CloudFlare's techniques for detecting and filtering DDoS traffic, such as consistent hashing to distribute loads across servers and FlowSpec to automate rate limiting attacks. Finally, it addresses challenges with connectivity in Africa and improving performance by moving content delivery closer through regional peering.
This document discusses using a cloud-based sandbox called SitC for malware analysis. It provides two use case examples of analyzing the CosmicDuke and Epic Turla advanced persistent threats. It then compares the report features of various sandbox solutions and provides sample SitC reports. It outlines the incident response workflow and technical requirements for deploying SitC. The document concludes that SitC could be useful for malware detection and analysis tasks and offers one of the most comprehensive reports currently available.
Threat Analysis on Win10 IoT Core and Recommaended Security Measures by Naohi...CODE BLUE
Windows 10 IoT was released as a platform for IoT.
Windows 10 IoT Core, which is the lightest among Windows 10 IoT, is usable without charge, and can be run on single board computers like Raspberry Pi. So far, Linux-based platforms were considered as the platform for IoT devices, but now there is another option.
We conducted research on security system of Windows 10 IoT Core to judge whether it could be used safely.
We investigated the security design, the security functions, and default services, such as Web, FTP, and SSH, served by this OS. Furthermore, we also analyzed risks of intrusion and malware infection.
As a result of the investigation, like the newest Windows, we found that DEP, ASLR and CFG are also effective as countermeasures for being attacked vulnerabilities that affect the main memory. These countermeasures are not omitted from Windows 10 IoT Core.
On the other hand, we also found some designs and default settings of services and components are insecure.
For example, Windows update is disabled, Windows Firewall is disabled by default settings, Web interface is served on HTTP, and its authentication is basic authentication.
Moreover, we found a problem in the design of the remote debug service. This problem allows an attacker to create any user account and intrude using the web interface or SSH. Therefore, this problem might be abused by worm malware.
Lastly, we will introduce recommended security measures such as disabling unused services, changing settings, enabling the firewall, enabling web interface on HTTPS, etc.

Zaccone Carmelo - IPv6 and security from a user’s point of view IPv6 Conference
This document discusses the IPv6 deployment at AWT.be from a security perspective. It describes how AWT.be initially deployed IPv6 separately from IPv4 using dedicated firewalls and networks. They then transitioned to dual-stack deployment after gaining experience. Key lessons included ensuring firewall and application support for IPv6, careful address configuration to avoid errors, and awareness that dual-stack hosts are more vulnerable without personal firewalls that support IPv6. The deployment approach aimed to safely gain experience with IPv6 before integrating it fully into production networks and services.
This document summarizes Jair Santanna's PhD research into the booter phenomenon of DDoS-for-hire websites. It describes how he developed techniques to automatically find booter websites, monitor their users, analyze the attacks they carried out, distinguish booters based on attack traffic, and identify third parties that support booter operations. His goal was to fully understand the booter ecosystem in order to evaluate legal and ethical mitigation strategies. He published several papers on different aspects of his research and plans to defend his thesis in November.

85. assignment:
How much network traffic a computer using your residential connection can
generate with 100 DNS servers as amplifiers?
- Print screen of your Internet SpeedTest;
- The amplification factor interval of DNS servers (considering DNSsec);
- The calculation and the result;
Who are the top 10 amplifier that sent more traffic?
- Choose on of the DNS-based attack available in http://www.simpleweb.org/
wiki/Traces#Booters_-_An_analysis_of_DDoS-as-a-Service_Attacks;
- Describe step-by-step how did you find the top 10 amplifiers using
Wireshark or TCPdump;
- Which DNS request was used in this attack;
- Where those top 10 amplifiers are located? (use https://
