What happens when an attack is carried out within
an organization? They usually do not know they
have been targeted therefore, they do not do
anything. However, once they discover it, the
most common reaction is panic, as it is similar
to being mugged.

When an organizations reputation, income, and
customer trust are at stake, the ability to
detect and respond to cybersecurity incidents and
events is vital. The earlier your company can
identify and respond to a data breach or even a
security event, the less likely it is to
significantly impact your data, customer trust,
reputation, and revenue. A structured strategy to
dealing with and managing the consequences of a
security breach or cyberattack is incident
response. What use would it be to be a
Cybersecurity Analyst if you didnt know how to
respond to a security incident? The CompTIA CySA
certification prepares IT professionals to detect
and respond to any security incident or event
that may occur. The goal is to provide knowledge
to manage the situation in such a way that harm
is limited and recovery time and expenditures are
minimized.

  learn how to classify threats and analyze the
  impact of cybersecurity incidents, the
  significance of communication throughout a
  cybersecurity incident response effort, the
  symptoms of an ongoing incident, how to use
  forensic tools, and how to recover from an
  incident.
• The fourth domain of the CompTIA CySA
  certification exam covers the following
  subtopics
• Explain importance of the incident response
  process
• Given the scenario, apply the appropriate
  incident response procedure
• Given an incident, analyze potential indicators
  of compromise
• Given the scenario, utilize basic digital

1. Explain importance of the incident response
process Responding immediately to an incident
will help an organization minimize damages,
mitigate exploited vulnerabilities, restore
services and procedures, and lower the risk of
future incidents. The primary purpose of incident
response is to limit the scope of an incident,
minimize the threat to organizational systems and
data, and promptly restore impacted systems and
data to operational status. This section will
explore the importance of the incident response
process within an organization and explain the
significance of communication during the incident
response process. This section includes the
communication plan like limiting communication to
trusted parties, using a secure method of
communication, preventing accidental release of
information, reporting requirements, response
coordination with relevant entities like legal,
human resource, regulatory bodies, and more. The
section also covers various factors contributing
to data criticality.

2. Given the scenario, apply the appropriate
incident response procedure This section deals
with the application of an effective incident
response procedure. Every incident response
strategy should include several steps, which
include preparation, detection and analysis,
containment, eradication and recovery, and
post-incident operations, to successfully cover
all bases and address the wide spectrum of
potential security threats. A robust incident
response plan should enable you to deal with a
wide range of events that could potentially harm
your business. Each possible scenario should be
described in the plan and the procedures taken to
reduce the damage. 3. Given the incident,
analyze potential indicators of compromise The
section delves into the most common network,
host, and application symptoms that could
indicate a compromise. Data that suggest a cyber
attack has infiltrated a system are Indicators of
Compromise (IOCs). They provide critical
information to cybersecurity professionals in the
aftermath of a data breach or other security
breach. You will learn how to evaluate these
potential Indicators of Compromise (IOCs).

4. Given the scenario, utilize basic digital
forensics techniquesThis section will discuss
the basic digital forensics techniques. It
describes how to distinguish threat data or
behavior in order to determine the severity of an
incident, put together a toolkit, and use
relevant forensics tools during an investigation.
It includes network, endpoint, memory, mobile,
cloud, virtualization, legal hold, procedures,
hashing, carving, and data acquisition.
