Ch 22: Web Hosting and Internet Serverswebhostingguy
Web hosting involves providing space on a server for websites. Linux is commonly used for hosting due to its maintainability and performance. A web server software like Apache is installed to handle HTTP requests from browsers. URLs identify resources on the web using protocols like HTTP and FTP. CGI scripts allow dynamic content generation but pose security risks. Load balancing distributes server load across multiple systems. Choosing a server depends on factors like robustness, performance, updates, and cost. Apache is widely used and configurable using configuration files that control server parameters, resources, and access restrictions. Virtual interfaces allow a single server to host multiple websites. Caching and proxies can improve performance and security. Anonymous FTP allows public file downloads.
This document discusses using Ubuntu to set up an intranet server to provide essential services like DNS, DHCP, mail, file sharing, printing, authentication, firewall, web, and content management. It describes configuring these services and considerations for an intranet like security, administration, bandwidth savings, and offline access within an organization. Alternative options like hosting services and Google Apps are also mentioned.

This chapter discusses ethical and social issues related to information systems. It introduces five moral dimensions to consider: information rights and obligations, property rights and obligations, accountability and control, system quality, and quality of life. New information technologies can raise new ethical, social, and political issues at the individual, organizational, and societal levels. The chapter also examines specific issues like privacy, intellectual property, computer crime, and how technology impacts work and life.
Servers are specialized computers designed to provide services or resources to multiple clients simultaneously. They have additional features like enhanced processing power, high-performance input/output, and redundancy options that justify their higher cost compared to individual workstations. Choosing reliable vendors is important, and servers should be placed in environments with proper infrastructure like power, cooling, and security. Remote management options help enhance reliability and serviceability.
RAID (Redundant Array of Independent Disks) is a technology that combines multiple disk drives into a single logical unit to improve data reliability, increase input/output performance, or achieve both. There are different RAID levels serving different purposes - RAID 0 stripes data across disks for performance; RAID 1 mirrors data across disks for redundancy; RAID 5 uses block-level striping with distributed parity for both performance and fault tolerance. The document then provides commands to implement a RAID 5 array using 3 disks on a RHEL system and test failure recovery functionality.
Authentication protocols allow communicating parties to verify each other's identities and establish secret session keys. They address confidentiality and timeliness issues like replay attacks. Approaches include timestamps and challenge-response protocols. Public key authentication enables parties knowing each other's public keys to mutually authenticate. Diffie-Hellman key exchange establishes a secret key based on each party's public key. Key distribution centers and protocols like Kerberos allow authentication through a trusted third party without pre-shared keys. Digital signatures authenticate message content and author, preventing later repudiation, while being verifiable by third parties. Direct signatures involve encrypting a message hash with a private key, while arbitrated signatures involve a trusted arbiter.
This document discusses key management and protocols for distributing public keys for use in public-key cryptography. It describes several problems with directly exchanging or posting public keys and introduces the concept of a public-key authority or certificate authority that can validate public keys. The document outlines some proposed solutions like a centralized public-key authority that maintains a directory of public keys or a hierarchical system of certificate authorities that can validate certificates within a public key infrastructure. It also discusses the X.509 standard format for public key certificates.
This document discusses professional practices related to organizational and team structures. It describes how teams develop through different stages and how organizations are typically structured into departments that oversee multiple projects. Projects are then assigned to teams that can be structured functionally with members from different specialized groups or using a project format with dedicated members. The document also discusses dispersed and virtual teams as well as leadership styles.
This document provides an overview and summary of key topics related to database design and management. It outlines the course contents, which include concepts of database management, database modeling, SQL, distributed databases, and database administration. It also discusses database terminology, the advantages of using a database management system (DBMS) compared to file-based systems, including improved data sharing and reduced redundancy. The components of a DBMS environment are identified as hardware, software, data, procedures, and people.

3. Samba
• Free software re-implementation of the SMB networking protocol
• File and print services for various Microsoft Windows clients
• Integration with a Microsoft Windows Server domain, either as
a Domain Controller (DC) or as a domain member
• Version 4 Active Directory and Microsoft Windows NT domains
• Runs on most Unix-like systems, such as Linux, Solaris, AIX and
the BSD variants, including Apple's macOS Server,
and macOS client (Mac OS X 10.2 and greater).
4. Samba
• Runs on a number of other operating systems such
as OpenVMS and IBM i.
• Samba is standard on nearly all distributions of Linux and is
commonly included as a basic system service on other Unix-based
operating systems as well.
• Samba is released under the terms of the GNU General Public
License.
• The name Samba comes from SMB (Server Message Block), the
name of the proprietary protocol used by the Microsoft Windows
network file system.
5. Security of Samba
• Some versions of Samba 3.6.3 and lower suffer serious
security issues which can allow anonymous users to gain
root access to a system from an anonymous connection,
through the exploitation of an error in Samba's remote
procedure call.
• On 12 April 2016, Badlock, a crucial security bug in Windows
and Samba, was disclosed.
6. Security of Samba
• On 24 May 2017, it was announced that a remote code
execution vulnerability had been found in Samba named
EternalRed or SambaCry, affecting all versions since 3.5.0.
• On 14 September 2020, a proof-of-concept exploit for the
netlogon vulnerability called Zerologon (CVE-2020-1472) for
which a patch exists since August was published. Some
federal agencies using the software have been ordered to
install the patch.
7. File Transfer Protocol (FTP)
• Standard communication protocol used for the transfer of computer
files from a server to a client on a computer network.
• Built on a client–server model architecture using separate control
and data connections between the client and the server
• FTP users may authenticate themselves with a clear-text sign-in
protocol, normally in the form of a username and password, but can
connect anonymously if the server is configured to allow it.
• For secure transmission that protects the username and password,
and encrypts the content, FTP is often secured with SSL/TLS (FTPS)
or replaced with SSH File Transfer Protocol (SFTP)
8. File Transfer Protocol (FTP)
• The first FTP client applications were command-line programs and are still
shipped with most Windows, Unix, and Linux operating systems.
• Many dedicated FTP clients and automation utilities have since been developed
for desktops, servers, mobile devices, and hardware.
• FTP has been incorporated into productivity applications such as HTML editors
and file managers.
• An FTP client used to be commonly integrated in web browsers, where file
servers are browsed with the URI prefix "ftp://".
• Throughout 2021, the two major web browser vendors removed this ability
9. Data transfer modes in FTP
• Stream mode (MODE S):
• Data is sent as a continuous stream, relieving FTP from doing any processing.
• Rather, all processing is left up to TCP.
• No End-of-file indicator is needed, unless the data is divided into records.
• Block mode (MODE B):
• Designed primarily for transferring record-oriented files (STRU R), although can also
be used to transfer stream-oriented (STRU F) text files.
• FTP puts each record (or line) of data into several blocks (block header, byte count,
and data field) and then passes it on to TCP.
• Compressed mode (MODE C):
• Extends MODE B with data compression using run-length encoding.
10. Security in FTP
• FTP was not designed to be a secure protocol, and has many security weaknesses.
• In May 1999, the authors of RFC 2577 listed a vulnerability to the following problems:
• Brute-force attack
• FTP bounce attack
• Packet capture
• Port stealing (guessing the next open port and usurping a legitimate connection)
• Spoofing attack
• Username enumeration
• DoS or DDoS
11. Network File System (NFS)
• A distributed file system protocol originally developed by Sun Microsystems
(Sun) in 1984, allowing a user on a client computer to access files over a
computer network much like local storage is accessed.
• NFS, like many other protocols, builds on the Open Network Computing Remote
Procedure Call (ONC RPC) system.
• NFS is an open IETF standard defined in a Request for Comments (RFC),
allowing anyone to implement the protocol.
12. Version of NFS
• NFSv1
• for in-house experimental purposes
• NFSv2
• operated only over User Datagram Protocol (UDP)
• NFSv3
• Support 64 bits file sizes
• WebNFS
• Allowing it to function behind restrictive firewalls without the complexity of Portmap and MOUNT
protocols.
• WebNFS had a fixed TCP/UDP port number (2049)
• NFSv4
13. Apache HTTP Server
• Free and open-source cross-platform web server software
• Developed and maintained by an open community of developers under the
auspices of the Apache Software Foundation.
• The vast majority of Apache HTTP Server instances run on a Linux distribution
but current versions also run on Microsoft Windows, OpenVMS and a wide
variety of Unix-like systems
• As of March 2022, Netcraft estimated that Apache served 23.04% of the million
busiest websites
14. Security of Apache HTTP Server
• Can be hacked and exploited.
• The main Apache attack tool is Slowloris, which exploits a bug in Apache
software.
• It creates many sockets and keeps each of them alive and busy by sending
several bytes (known as "keep-alive headers") to let the server know that the
computer is still connected and not experiencing network problems.
• The Apache developers have addressed Slowloris with several modules to limit
the damage caused
15. Docker
• Set of platform as a service (PaaS) products that use OS-level virtualization to
deliver software in packages called containers.
• The service has both free and premium tiers.
• The software that hosts the containers is called Docker Engine.
• It was first started in 2013 and is developed by Docker, Inc.
