Study Notes

Server Roles

Servers manage access to centralized network resources and can perform multiple roles based on network needs.
Common roles include DNS (Domain Name System), DHCP (Dynamic Host Configuration Protocol), print servers, and mail servers.

Access Roles

Servers can provide access to files, printers, websites, and security logs.
Configuration starts with enabling the appropriate server role in systems like Windows Server.

Servers typically share files and folders, allowing for user access management.
Permissions can be adjusted to read-only, write, or full control, with explicit denial options for specific folders.
Access to files can be configured remotely using protocols such as FTP or Windows Server Remote Web Access.

Print Servers

Print servers manage multiple network printers, allowing centralized access for users.
Administrators can manage security settings and monitor usage from a single location.

Web Servers

Organizations maintain web servers to manage their websites and internal intranets.
Microsoft servers use Internet Information Services (IIS), while Linux servers typically utilize Apache.

Server Security

Ensures users are authenticated, authorized, and monitored when accessing the network.
System logs capture significant events, providing accountability and oversight.

Domain Name System (DNS)

DNS matches hostnames with IP addresses, making it easier for users to access resources.
Hierarchical structure: root level, top-level domains (.com, .net), domain names (unique to organizations), and hostnames.
There are 13 root DNS servers and more than 1,500 top-level domain names.

DNS Records

A records map hostnames to IPv4 addresses; AAAA records do this for IPv6.
Mail Exchange (MX) records identify email handling servers; TXT records store plaintext notes for verification and spam prevention.

Dynamic Host Configuration Protocol (DHCP)

DHCP automates IP address assignment, crucial for large networks.
Configuration includes defining the IP address range, exclusion/reservation addresses, lease time, and default gateway.
Exclusions prevent IP assignments, while reservations assign specific IPs based on MAC addresses.

Mail Servers

Email communication is facilitated through mail servers using various protocols.
SMTP (Simple Mail Transfer Protocol) is used for sending emails; IMAP (Internet Message Access Protocol) and POP3 (Post Office Protocol version 3) are used for receiving emails.
Implementing security measures like DKIM, SPF, and DMARC helps reduce email spam and validate sender authenticity.

Summary

Servers provide essential network resources such as file sharing, printing, web hosting, DNS management, DHCP for IP configurations, and email services.
Understanding and configuring these roles and protocols enhances network efficiency and security.
