inContext: On Coupling and Sharing Context for Collaborative Teams
This document discusses techniques for coupling and sharing context among collaborative teams and services. It presents an approach using RDF models to represent individual, team, and activity context at design time. At runtime, context is coupled across services by embedding URIs specifying context in SOAP message headers. This allows services to access distributed context from a central store using queries. The techniques aim to provide services with greater awareness of the overall collaboration context with minimal changes to existing services. Future work involves developing a reference architecture and applying the approach to specific collaborative projects.
Community Clouds from Scratch
Cloud Computing represents a radical change in the way we organize and use computing resources and storage. The scientific and academic communities face the challenge of not only adapting their procedures to this new paradigm, but also contributing Cloud Computing development and leading its evolution towards open, secure and interoperable computing infrastructures, which will playing a key role in the community clouds paradigm.
The Spanish MEGHA initiative promotes and coordinates contributions to cloud computing R&D, education and management made by institutions affiliated with RedIRIS [7] in Spain. In the first phase (2010–2012), MEGHA validated federated cloud platforms using Opennebula and OCCI [10] to streamline the use of cloud technologies among R&E service centers. Representative infrastructure providers (CESCA, CESGA, PIC), middleware providers (OpenNebula, RedIRIS, OSAmI-Commons) and users (UAB, UOC, UM) together with intermediate/identity/brokers resources (RedIRIS) joined efforts to demonstrate the viability of this approach.
The results stimulated the development of use cases including e-learning platforms on demand (Learning Apps project), a distributed HPC platform (e-Science), and Virtual Labs (VDI) in a hybrid scenario (Academic services).
Next Steps?
As next goal, the Spanish research and academic community is working to assess the possibilities of creating a productive Infrastructure Cloud Computing service within member institutions. With this new approach new challenges appear:
Federated user authentication and authorization mechanisms.
Brokering architecture scenario.
Secure VM image distribution and validation.
A federated cloud accounting system integrating the accounting records of multiple cloud managers and supporting federated cloud governance.
Monitoring and notification of unpredictable changes in availability and readability status.
Security Policies and Service Level Agreements (SLA’s).
Towards Formal-based Semantic Interoperability in Multi-Clouds (CLOUD'2017)
Multi-cloud computing has been proposed as a way to reduce vendor lock-in, to improve resiliency during outages and geo-presence, to boost performance and to lower costs.
However, semantic differences between cloud providers, as well as their heterogeneous management interfaces, make changing from one provider to another very complex and costly. This is quite challenging for the implementation of multi-cloud systems. In this paper, we aim to take advantage of formal methods to define a precise semantics for multi-clouds. We propose FCLOUDS, a formal-based framework for semantic interoperability in multi-clouds. This framework contains a catalogue of formal models that mathematically describe cloud APIs and reason over them. A precise alignment can be described between their concepts, which promotes semantic interoperability.

The document also provides steps to install and run FireQOS on CentOS7 and presents a sample network topology for testing bandwidth control.
Bidirectional Forwarding Detection (BFD)
BFD is a protocol that can quickly detect failures in the forwarding path between two adjacent routers, including interfaces, data links, and forwarding planes. It operates in two modes: asynchronous mode where it periodically sends control packets, and demand mode where it only sends packets when needed. When a failure is detected, BFD triggers routing protocol actions to recalculate the routing table and reduce convergence time. It provides fast failure detection independently of media, encapsulation, topology, or routing protocol. Configuring BFD involves setting intervals at the interface level and enabling it for routing protocols.
Network Exploitation
This document provides an overview of network exploitation and the Metasploit framework. It begins with definitions of key terms like vulnerability, exploit, and payload. It then explains the basic process of exploitation as using an exploit to trigger a payload after a vulnerability is triggered. The document outlines common steps attackers use like port scanning and service identification. It introduces the Metasploit framework as an open-source tool for penetration testing and exploit development with over 770 tested exploits and 228 payloads. It concludes with examples of using tools like nmap for port scanning and compiling exploits to demonstrate exploitation of a known vulnerability.

HSNM is a Linux-based carrier class all-in-one network appliance or VMware player that provides radius, syslog, and SMS services for authentication and management of Mikrotik hotspots and PPOE servers. It includes a web administration panel for customizing hotspot login pages and generating configuration files. HSNM allows multi-level access for administrators, resellers, network managers and users.
Virtual Extensible LAN (VXLAN)
VXLAN allows layer 2 segments to span layer 3 networks by encapsulating Ethernet frames within UDP packets. This allows virtual machines and servers to communicate securely across physical networks as if they were on the same local area network. VXLAN uses VXLAN Tunnel End Points and a VXLAN Network Identifier to encapsulate packets and identify virtual network segments. Up to 16 million virtual networks can be created, enabling data center tenants and workloads to be isolated from each other while residing on the same physical network.
Best Practices Fiber and SFP Inspection
The document discusses the importance of regularly inspecting fiber optic connectors to avoid network failures. It notes that network owners report having connector issues in 80% of cases. Cleaning alone is not enough to maintain connectors - inspection is needed to check for damage. Inspection allows technicians to know if cleaning is required and avoids assuming cleaning was sufficient. Automated inspection tools that provide pass/fail analysis can reduce subjective decision making about connector quality and need for repair. Regular comprehensive inspection of connectors can help avoid costly issues down the line such as troubleshooting unknown problems and network upgrades being needed sooner.
BGP

1834902097 class note 3
The document discusses the OSI and TCP/IP models and network addressing.
The OSI model has 7 layers - physical, data link, network, transport, session, presentation, application. The TCP/IP model combines the session and presentation layers into the application layer and has 4 layers - physical, data link, internet, transport.
There are two types of network addresses - physical and logical. Physical addresses refer to MAC addresses that identify devices. Logical addresses are created by network layer protocols like IP and map to physical addresses.

introduction about TCP/IP
The document compares the OSI model and the TCP/IP model. The OSI model has 7 layers - physical, data link, network, transport, session, presentation and application layers. It defines a generic standard for network communication. The TCP/IP model has 4 layers - network access, internet, transport and application layers. It is based on specific TCP and IP protocols and is used widely for internet working. The key difference is that OSI model is protocol-independent while TCP/IP model supports specific protocols for internet.

Removing Uninteresting Bytes in Software Fuzzing
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.
