This document discusses how corporate firewalls work to protect organizational computer networks from outside intrusion. A firewall is a system that uses a bastion host, which acts as a fortress computer, to prevent networks connected to the internet from being invaded. Firewalls work by routing network data through this secure bastion host using protocols like FTP and connections between networks via routers.

The document discusses the Storm worm, which first emerged in 2007 and uses a peer-to-peer network and rootkit technology to spread and avoid detection. It spreads through email and phishing websites. As it has evolved, Storm can send spam, conduct DDoS attacks, and download files. It uses a decentralized P2P architecture and encrypts traffic between bots using XOR encryption, making it difficult to trace. The rootkit technology allows it to hide processes, files, ports, and services to avoid detection by anti-virus software. Analysis of Storm's P2P network revealed over 5,796 infected hosts communicating within 21 minutes.Linux Basic Networking Command

The document discusses Python FUSE (Filesystem in Userspace) which allows users to create their own filesystems in userspace without modifying the kernel. It provides an overview of filesystem concepts, a brief history of filesystem development, and introduces FUSE as a way to develop filesystems using Python and other languages. Code examples are provided demonstrating how to create a basic hash table based filesystem in Python using the FUSE API.際際滷

The document discusses several key concepts in circuit-switched digital networks:
TCP is a transmission control protocol that controls the data link layer and is used for communication processing in TCP/IP. LAN uses Ethernet and TCP/IP, the common internet protocol. ISDN is an integrated digital network that allows both packet and circuit-switched digital communication. IP is the internet protocol that transmits information across the internet. A modem modulates and demodulates signals to allow communication over phone lines.Week10 G

Routers come in a variety of sizes and are used to connect devices to networks. Small home routers often include an Ethernet switch. Dynamic Host Configuration Protocol (DHCP) is used by network devices to automatically obtain IP address and other configuration settings when connecting to a network. NAT routers use DHCP to assign private IP addresses to clients, while non-NAT routers assign public IP addresses. A local area network (LAN) is a computer network covering a small physical area like a home or office, while a wide area network (WAN) connects multiple LANs over a larger geographic distance. Internet Protocol (IP) is commonly abbreviated and refers to the protocol that allows devices to communicate over the internet or networks.W13

The document lists student IDs, defines common network terms like firewall, CGI, HTML, and intranet. A firewall blocks unauthorized access while allowing authorized communication. CGI is a low-level interface between a graphical kernel system and hardware. HTML is an initialism for Hypertext Markup Language. An intranet is separated from the public internet by a firewall, allowing corporate employees internet access while also giving outsiders access to certain intranet parts.

Looking backwards, this talk will show how UX has repeatedly failed to create a better world, drawing on industry data from Nielsen Norman Group, Baymard, MeasuringU, WebAIM, and others.
Looking forwards, this talk will argue that UX must resist hype, say no more often and collaborate less often (you read that right), and become a true profession in order to be able to design a better world.How Discord Indexes Trillions of Messages: Scaling Search Infrastructure by V...

Regularly run repairs are essential to keep clusters healthy, yet having a good repair schedule is more challenging than it should be. Repairs often take a long time, preventing running them often. This has an impact on data consistency and also limits the usefulness of the new repair based tombstone garbage collection. We want to address these challenges by making repairs incremental and allowing for automatic repair scheduling, without relying on external tools.際際滷.Week14
