A proxy server is a server that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity.
Proxy servers sit between an internal network and an external network. They act as an intermediary for requests from the internal users to hide their IP addresses and improve security. Proxy servers terminate TCP connections, caching frequently requested files to improve performance, and can filter content to enforce security policies. They provide anonymity and security for internal users while allowing access to external networks and resources.
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.
A web proxy server acts as an intermediary between clients and external servers on the internet. It protects clients by filtering traffic and limiting outside access. When a client requests a resource, the proxy server evaluates the request according to its rules before forwarding it to the external server. It then sends the response back to the client. This allows all clients connected to the proxy server to access the internet from behind the firewall with improved security and performance. The proxy server can also cache frequently requested resources to speed up access.
A proxy server acts as an intermediary between a client device and the internet. It allows clients on a local network indirect access to outside networks like the internet. There are different types of proxy servers that provide advantages like improved security and performance through caching but also have disadvantages like potential slower speeds. Popular proxy server software includes Microsoft ISA Server, Squid, and WinRoute, while common hardware proxies include Cisco PIX and Blue Coat.
A firewall sits between private and public networks like the Internet to protect computers from unauthorized access. There are different types of firewalls that operate at different layers, including packet filtering firewalls that work at the network layer, circuit-level firewalls that work at the session layer, and application-level firewalls that filter at the application layer. Stateful multilayer firewalls combine aspects of these approaches and can determine if a packet is part of an existing connection. Proxy servers act as intermediaries for client requests to other servers and can filter traffic according to rules.
This document discusses HTTP proxy servers. It defines a proxy server as a server that acts as an intermediary for requests from clients and acts as a client to the actual servers. An HTTP proxy server specifically handles HTTP requests. It can speed up browsing by caching frequently requested pages. It also anonymizes user requests and reduces load on the internet connection. The document then discusses the software Proxyfire as an example of a "distorting" HTTP proxy server and provides screenshots of its interface. It concludes by listing the hardware and software specifications of the system used.

James Tramel discussed how SharePoint can be accessed from outside a network using Forefront Unified Access Gateway (UAG). UAG acts as a reverse proxy and VPN solution to securely publish SharePoint and other line of business applications externally. It is important to understand the network topology and infrastructure in order to properly configure UAG, SharePoint alternate access mappings, and server certificates. A demonstration of a sample UAG and SharePoint extranet configuration was provided.
This document discusses various web communication protocols used for connectivity of devices over constrained and unconstrained environments. It describes protocols like CoAP, DTLS, JSON and TLV formats that allow small devices with limited resources to communicate securely over the web. CoAP is a specialized web transfer protocol that uses request/response model and supports resource discovery. DTLS provides security services like integrity, authentication and confidentiality for UDP-based applications. JSON and TLV are compact data formats used for message transmission.
HTTP is a request-response protocol for transferring data over the internet. It was introduced by Tim Berners-Lee at CERN. The client submits an HTTP request to the server, which responds with status information and requested content. HTTP uses TCP for network connectivity and relies on DNS to connect clients to servers. HTTP 1.0 defined GET, POST, and HEAD methods, while HTTP 1.1 added PUT, DELETE, TRACE, OPTIONS, and CONNECT. Persistent connections allow multiple requests/responses over a single TCP connection, improving efficiency versus non-persistent connections requiring separate TCP for each transaction.
HTTP is the set of rules for transferring data across the World Wide Web. It uses clients like web browsers to make requests to servers using URLs over TCP/IP. HTTP defines request and response messages with request methods like GET and POST and response status codes. HTTP 1.1 supports persistent connections and caching via proxy servers for improved performance over HTTP 1.0.
Virtual private networks (VPNs) allow secure communications over the public Internet by encrypting data and tunneling it through virtual connections. VPNs function like private leased lines but provide a more cost-effective way to connect remote users and offices. Essential VPN components include encryption endpoints, tunnels to encapsulate data, and authentication of users and devices on the private network. Common VPN setups are either mesh architectures with direct connections between all sites or hub-and-spoke with connections terminating at a central server. Protocols like IPSec and IKE enable encryption and key exchange to securely transmit data over VPN tunnels.
This document discusses various types of proxy servers including anonymous proxy servers, HTTP proxy servers, FTP proxy servers, caching proxy servers, content filtering proxy servers, reverse proxy servers, and ICAP servers. It provides details on their functions and purposes. Team members on the Awesum4sum project are listed and an index outlines topics covered which include introduction to proxy servers, advantages and disadvantages, and a demonstration on CC Proxy.
This PPT aims at providing information about web servers in general and in brief initially, to create the foundation for grasping more detailed information about Proxy Servers in particular. The major content of this PPT is meant to provide useful information about Proxy Servers that will enable one to understand this type of server and its uses and types.
HTTP is the protocol that powers the web. It uses a request-response model where clients make requests that servers respond to. Common request methods include GET, POST, HEAD, PUT, DELETE, and OPTIONS. Responses include status codes like 200 for OK and content types. HTTP 1.1 added features like persistent connections and chunked encoding. Cookies are used to maintain statelessness. HTTPS uses SSL/TLS to secure HTTP connections with encryption, server authentication, and integrity.
BlazeDS allows Flex and AIR applications to connect to backend services and push real-time data. It provides remoting, messaging, and proxy services. The messaging service uses a publish-subscribe model with channels and destinations. Producers publish and consumers subscribe to messages. Simple polling periodically checks for messages but long polling and streaming maintain open connections for lower latency. Configuration determines which messaging protocol to use.
HTTP headers carry important information in web requests and responses between browsers and servers. They define the request and response details like the request method, resources used, sender and receiver details, and content type. Common HTTP headers provide information on the request method, resources consumed, sender and destination, and content type. Tools like the Live HTTP Headers browser add-on or inspect element can be used to view HTTP headers and their carried information.

JSON SQL Injection and the Lessons LearnedKazuho Oku
This document discusses JSON SQL injection and lessons learned from vulnerabilities in SQL query builders. It describes how user-supplied JSON input containing operators instead of scalar values could manipulate queries by injecting conditions like id!='-1' instead of a specific id value. This allows accessing unintended data. The document examines how SQL::QueryMaker and a strict mode in SQL::Maker address this by restricting query parameters to special operator objects or raising errors on non-scalar values. While helpful, strict mode may break existing code, requiring changes to parameter handling. The vulnerability also applies to other languages' frameworks that similarly convert arrays to SQL IN clauses.
This document provides an overview of basic network and security concepts. It discusses TCP/IP, routing, DNS, NAT, firewalls, tunneling, and DMZs.

This document summarizes a summer internship project to implement a proxyless internet access system for a university campus network. The interns configured PfSense open source firewall/router software with Squid and Captive Portal to provide transparent proxy access along with user authentication. They implemented load balancing, high availability, and deep packet inspection for security and performance. The system allows all applications like Windows, Android, and iOS to access the internet without proxy settings while still providing logging and content filtering.
This document discusses network security and firewalls. It explains that network security aims to create a secure computing platform and protect systems from hackers through devices like firewalls. Firewalls examine incoming and outgoing messages on a network and block those that do not meet security criteria. They can filter network traffic using packet filtering, proxy services, or stateful inspection. Firewalls are customizable and can filter based on IP addresses, domains, protocols, and other conditions to control network access and traffic flow.
A firewall controls incoming and outgoing network traffic to protect devices from attacks. There are three main types: edge firewalls protect individual devices; appliance firewalls are dedicated firewall devices; and network firewalls protect entire networks using routers, bridges, or computer-based software. Firewalls are used to protect networks from probes and attacks, and provide security for less protected devices. Proxies act as intermediaries for network requests, allowing things like caching, filtering, authentication, and load balancing to improve security and performance. Reverse proxies specifically allow external users indirect access to internal servers and websites.
This document describes the network structure of UPM. It details how various systems within UPM like the website, email, databases etc are connected and separated within the network. Firewalls, routers, switches, proxy servers and wireless access points are used to structure the network, control access to resources, and ensure security. The network uses private IP addresses that are converted to public IPs for internet access via a firewall. Systems like iDEC and GSM are separated within the network to restrict access and manage traffic between different parts of the university.

The document proposes a solution to allow apps to work seamlessly while still utilizing proxy server functionality like filtering and monitoring. The solution uses a transparent proxy and captive portal for authentication. A test bed was created using VirtualBox VMs including pfSense firewall, which has integrated proxy and captive portal services. Windows 8 and Ubuntu apps were tested and worked successfully without compromising proxy features. The proposed open source solution is widely applicable and cost-effective.
Design and Configuration of App Supportive Indirect Internet Access using a ...IJMER
Nowadays apps satisfy a wide array of requirements but are particularly very useful for educational institutions trying to realize their mobile learning systems or for companies wishing to bolster their businesses. A company/institute that wants to perform web filtering, caching, user monitoring etc. and allow Internet access only after authentication might use an explicit proxy. It has
been observed that most of the apps that need to connect to the Internet through an explicit proxy, do not
work whatsoever. In this paper, a solution has been proposed to get the apps working without having to
avoid the use of a proxy server. The solution is developed around transparent proxy and makes use of a captive portal for authentication. Oracle VM VirtualBox was used to develop a test bed for the experiment and pfSense was used as the firewall which has both proxy server and captive portal services integrated on a single platform. When tested, Windows 8 apps as well as Ubuntu apps worked well without sacrificing proxy server services such as web filtering. The proposed solution is widely
applicable and cost-effective as it uses open source software and essentially the same hardware as used
for explicit proxy deployments.

mumble: Framework for Seamless Message Transfer on SmartphonesAnand Bhojan
This work explores the possibility of transferring data between mobile devices that are nearby each other without the need of pairing, authentication, superuser access and Internet connectivity. Such technology can be used for emergency broadcast, traffic congestion avoidance, IoT, smart city, social and dating systems and games. Except Bluetooth Low Energy technology, there is no other protocol or technology available that allows pairing-free data transfer without Internet connectivity. Bluetooth Low Energy is capable of doing so but at a relatively short range. Using Wi-Fi Direct's Service Broadcast and Discovery, a simple yet novel method is developed which allows for seamless long range (Wi-Fi range) data transfer without Internet connectivity.
The design details of FATS-mumble can be found in the paper (http://www.comp.nus.edu.sg/~bhojan/papers/mumble15.pdf) published in ACM Mobicom 2015 SmartObjects. Please use it for all the references of this mumble project.

1) Establishing baseline performance metrics and monitoring the server to identify bottlenecks. Common bottlenecks include incorrect settings, faulty resources, insufficient resources, or applications hogging resources.
2) Caching web content and using proxy arrays, network load balancing, or round robin DNS to distribute load across multiple proxy servers for improved performance and high availability.
3) Monitoring server components like CPU usage, memory usage, disk performance, and network bandwidth to identify optimization opportunities.
In today’s corporate environment employee access to Internet resources is, for many, a daily job function. Fundamentally, the web is utilized for simple day-to-day operations including virus updates, software patches and hardware drivers and other network administrator duties in private proxy. Other divisions of an organization may require the World Wide Web for resources such as market updates, company news, and general research on products or competitor’s products. In today’s business environment, access to the World Wide Web is no longer an option for many companies, but instead a requirement.

An Internet Protocol address is a numerical label assigned to each device participating in a computer network that uses the Internet Protocol for communication. An https private proxy address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there
A Paid proxy is a server that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity. Proxies were invented to add structure and encapsulation to distributed systems. Today, most proxies are web proxies, facilitating access to content on the World Wide Web.

Proxy server can control bandwidth and limit network bandwidth for companies. It monitors bandwidth usage and creates statistics reports. Users' browsing speed and bandwidth can be controlled by setting maximum connections and download/upload bandwidth limits per client. The proxy also monitors total bandwidth usage and each client's current bandwidth. Bandwidth calculations can be done at intervals specified in options. Bandwidth control can apply to upload, download or both.
In order to optimize server performance for whatsoever reason, you need to start by monitoring the server. In most cases, before server monitoring commences, it is common practice to establish baseline performance metrics for the specific server.
Proxy servers can be optimized through caching, load balancing, and monitoring performance metrics. Caching web content on the local network improves performance by reducing bandwidth usage and speeding up access. Load balancing techniques like proxy arrays, network load balancing, and round robin DNS distribute traffic across multiple proxy servers for high availability and optimized performance. Monitoring components like CPU usage, memory, disk usage, and network bandwidth helps identify bottlenecks and areas for improvement.

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.

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.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

2. What is a Proxy Server /
VPN?
A virtual private network is defined as: a computer
network that is implemented in an additional software
layer on top of an existing larger network for the
purpose of creating a private scope of computer
communications
3. What does that mean in layman’s
terms?
When you type Facebook.com into your browser the
Great Firewall blocks access because that site is on
a list. Anything on the list cannot be accessed directly
from within the ‘Firewall because it controls incoming
and outgoing connections. A proxyproxy is an
intermediary server which is not on the list and it, in
turn, connects to any site you want since its access
is unrestricted. Once software is installed and
activated the process is seamless and you won’t
notice which sites are blocked and which aren’t.
Browse your friends Facebook photos to your hearts
content and tweet about them if you like.
4. Is this free?
Of the services available several are free and
monetized by advertising and others are ad-
free but require a monthly fee. The most well
known among free options was Hotspot
Shield, although it bombarded users with
advertisements and didn’t always work – that
was before it was blocked outright.
Unfortunately free proxies seem to get nailed
pretty quickly so if you want a reliable solution
you’ll be paying for the privilege of unrestricted
internet access.
5. A web proxy server is a program that makes
requests for web pages on behalf of all the
other machines on your intranet. The proxy
server will cache the pages it retrieves from
the web so that if 3 machines request the
same page only one transfer from the Internet
is required. If your organization has a number
of commonly used web sites this can save on
Internet accesses.
6. How fast is it? Are there any
downsides?
Since average internet speeds in China are
sub-par even for developing countries,
Freedur can easily max out my residential
2mb China Telecom internet connection which
at its fastest, is downloading at 200kb/s. The
Freedur application is small and works
flawlessly – once the accompanying Firefox
plugin is installed the giant On button works
like you’d expect.
7. Allowed subnets
In here, at least the subnets of the active
zones (no DMZ ) should be findable. The entry
of a subnetwork under this option allows
general access to the Web-proxyWeb-proxy.. If for
example, remote/local VPN networks or locally
connected networks that are neither in green
nor defined in blue should be connected to the
proxy, you just can enter the subnet with the
subnet mask in here.
8. The Network based access
control
Builds the main component of the "Access
control lists", and includes a few others, not
listed in the IPFire webinterface options. In
here the traffic control from Squid happens,
where the access to Squid and further from
Squid away can be managed.
9.
10. Disable internal proxy access to
Green from other subnets
If the proxyproxy is activated and used for both
zones (blue and green), there is the possibility
to reach the green zone from the blue zone
via http or https over the proxy. At this moment
the zone separation produced by IPTables is
bypassed. If this should be prevented, a hook
needs to be set.
11. Disable internal proxy access to
Blue from other subnets
If the proxy is activated and used for both
zones (blue and green), there is the possibility
to reach the blue zone from the green zone
via http or https over the proxy. At this moment
the zone separation produced by IPTables is
bypassed. If this should be prevented, a hook
needs to be set. However, a direct access
from green to blue is already possible
12.
13. Unrestricted IP addresses
All IP addresses which are listed in here have
no restrictions by the following regulation
areas of ”Time ristrictions”, ”Transfer limits” or
the ”MIME-type filter”.
14. Unrestricted MAC addresses
All MAC addresses which are listed in here
have no restrictions by the following regulation
areas of ”Time restrictions”, ”Transfer limits” or
the ”MIME-type filter”.
15.
Banned IP addresses:- All IP addresses that
are entered here will be completely blocked by
the proxy.
Banned MAC addresses:-All MAC addresses
that are entered here will be completely
blocked by the proxy.
16.
Unregistered IP's or MAC addresses:-IP or
MAC addresses which are neither entered in
the unrestricted section nor in the banned one,
are restricted by the ”Time restrictions”,
”Transfer limits” or/and the ”MIME-type filter”.
