What is Internet
•
The
internet
is a globally
connected
network system facilitating worldwide
communication and access to data resources through a vast collection of
private, public, business, academic and government networks. It is governed
by agencies like the
Internet
Assigned Numbers Authority (or IANA) that
establish universal protocols.
What does it mean when a computer is online?
•
With the Internet, it's possible to access almost any information,
communicate with anyone else in the world, and do much more. You
can do all of this by connecting a computer to the Internet, which is
also called going online. When someone says a computer is online, it's
just another way of saying it's connected to the Internet. What is the
Web?
Internet
•
The Internet is a global
wide area network
that connects computer systems
across the world. It includes several
high-bandwidth
data lines that comprise
the Internet "
backbone
." These lines are connected to major Internet
hubs
that
distribute data to other locations, such as
web servers
and
ISPs
.
•
In order to connect to the Internet, you must have access to an Internet service
provider (ISP), which acts as the middleman between you and the Internet.
Most ISPs offer
broadband
Internet access via a
cable
,
DSL
,
or
fiber
connection. When you connect to the Internet using a public
Wi-
Fi
signal, the Wi-Fi router is still connected to an ISP that provides Internet
access. Even cellular data towers must connect to an Internet service provider
to provide connected devices with access to the Internet.
Used of Internet
•
The Internet provides different
online
services. Some examples include:
•
Web
– a collection of billions of webpages that you can view with a web
browser
•
– the most common method of sending and receiving messages
online
•
Social media
– websites and
apps
that allow people to share comments,
photos, and videos
•
Online gaming – games that allow people to play with and against each
other over the Internet
Used of Internet
•
Software updates –
operating system
and
application
updates can
typically
downloaded
from the Internet
•
In the early days of the Internet, most people connected to the Internet
using a home computer and a
dial-up
modem. DSL and cable modems
eventually provided users with "always-on" connections.
Now
mobile
devices, such as
tablets
and
smartphones
, make it possible
for people to be connected to the Internet at all times. The
Internet of
Things
has turned common appliances and home systems into "smart"
devices that can be monitored and controlled over the Internet. As the
Internet continues to grow and evolve, you can expect it to become an
even more integral part of daily life.
Why Is Incident Management Important?
Why Is Incident Management Important?
•
Incident management refers to a set of practices, processes, and solutions that
enable teams to detect, investigate, and respond to incidents. It is a critical
element for businesses of all sizes and a requirement for meeting most data
compliance standards.
•
Incident management processes ensure that IT teams can quickly address
vulnerabilities and issues. Faster responses help reduce the overall impact of
incidents, mitigate damages, and ensure that systems and services continue to
operate as planned.
•
Without incident management, you may lose valuable data, experience reduced
productivity and revenues due to downtime, or be held liable for breach of service
level agreements (SLAs). Even when incidents are minor with no lasting harm, IT
teams must devote valuable time to investigating and correcting issues.
The Five Steps of Incident Resolution
There are five standard steps to any incident resolution process. These steps ensure
that no aspect of an incident is overlooked and help teams respond to incidents
effectively.
The Five Steps of Incident Resolution
1. Incident Identification, Logging, and Categorization
•
Incidents are identified through user reports, solution analyses, or manual
identification. Once identified, the incident is logged and investigation and
categorization can begin. Categorization is important to determining how incidents
should be handled and for prioritizing response resources.
The Five Steps of Incident Resolution
2. Incident Notification & Escalation
•
Incident alerting takes place in this step although the timing may vary according
to how incidents are identified or categorized. Additionally, if incidents are minor,
details may be logged or notifications sent without an official alert. Escalation is
based on the categorization assigned to an incident and who is responsible for
response procedures. If incidents can be automatically managed, escalation can
occur transparently.
The Five Steps of Incident Resolution
3. Investigation and Diagnosis
•
Once incident tasks are assigned, staff can begin investigating the type, cause,
and possible solutions for an incident. After an incident is diagnosed, you can
determine the appropriate remediation steps. This includes notifying any relevant
staff, customers, or authorities about the incident and any expected disruption of
services.
The Five Steps of Incident Resolution
4. Resolution and Recovery
•
Resolution and recovery involve eliminating threats or root causes of issues and
restoring systems to full functioning. Depending on incident type or severity, this
may require multiple stages to ensure that incidents don’t reoccur.
For example,
if the incident involves a malware infection, you often cannot simply
delete the malicious files and continue operations. Instead, you need to create a
clean copy of your infected systems, isolate the infected components, and fully
replace systems to ensure that the infection doesn’t spread.
The Five Steps of Incident Resolution
5. Incident Closure
•
Closing incidents typically involves finalizing documentation and evaluating the
steps taken during response. This evaluation helps teams identify areas of
improvement and proactive measures that can help prevent future incidents.
•
Incident closure may also involve providing a report or retrospective to
administrative teams, board members, or customers. This information can help
rebuild any trust that may have been lost and creates transparency regarding your
operations.

Keep in mind the font size (important for accessibility, visibility, videotaping, and online production)
Coordinated colors
Pay particular attention to the graphs, charts, and text boxes.
Consider that attendees will print in black and white or grayscale. Run a test print to make sure your colors work when printed in pure black and white and grayscale.
Graphics, tables, and graphs
Keep it simple: If possible, use consistent, non-distracting styles and colors.
Label all graphs and tables.
The internet is a globally connected network system that allows worldwide communication and access to data resources. It is governed by agencies like IANA, and connecting a computer to the internet enables access to information, communication globally, and more. The internet is a global wide area network that connects computer systems worldwide, facilitated by high-bandwidth data lines forming the backbone, and ISP acts as a middleman between users and the internet.
