CompTIA A+ 220-902

Summarize the properties and purpose

of services provided by network hosts

2.4

Server Roles

 Software that improves the functionality of the server

 Failover clustering

 Telnet client

Feature

 Software that allows a server to

perform a specific function for

multiple users and computers

Network Infrastructure Servers

 SMTP - Simple Mail Transfer

Protocol

- POP, IMAP

 Be careful with Internet

connectivity and relay

Show IIS config (permissions)

Demo 1: Web Server

Internet Appliances

Network Appliance

A relatively low-cost computer designed

chiefly to provide Internet access without the full capabilities of a standard computer

UTM/Proxy

 IDS that actually enacts workflow when an alarm is raised (eg

 Firewalls block incoming

connections, but IDS acts on internal

and external traffic

 When a known event occurs, device

raises an alarm (passive monitoring)

 Methods: Anomaly (baseline),

signature

IDS

IDS vs IPS

Legacy/Embedded

Systems

Embedded System

A computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints

 "A computer within a

computer"

 Has its own OS

 Microcontroller - CPU with

integrated RAM and

peripherals

 SCADA, traffic lights,

personal electronics

Embedded Systems

Is my game console vulnerable?

Back in the Real World…

Yes Keep it patched and watch the camera

 Use the Pluralsight library to build

 Pluralsight: Windows Server Administration Fundamentals Part 2 (Michael Bender)

- AD, DNS, DHCP, File and Print services

 Pluralsight: CompTIA Security+ (SYO-401) Network Security

(Chris Rees)

- See the module "Security Configuration Parameters"

For Further Learning

If core network services fail, then your network goes down

Don't forget to patch your

embedded systems (Smart TVs?)
