In this section of the course,
we'll be covering the incident response process.
The incident response process is a critical component
of cybersecurity that outlines a systematic approach
that an organization should take to manage
and mitigate security incidents effectively.
These incidents can range from cybersecurity attacks
and data breaches to system vulnerabilities
and unauthorized access.
The primary goal of an incident response
is to minimize the impact of security breaches,
reduce the time it takes to identify and contain threats,
and facilitate a swift recovery to normal operations.
This process typically involves several key steps,
including incident detection and classification,
containment and eradication of the threat,
evidence, preservation, communication and reporting,
and lessons learned for future preventions.
A well-defined incident response plan is essential
for organizations to maintain resilience in the face
of evolving cyber threats
and to safeguard their digital assets and reputation.
So in this section of the course,
we'll be solely focused on domain four,
more specifically, objective 4.8.
Objective 4.8 states that you must be able
to explain appropriate incident response activities.
First, we'll provide an overview
of the incident response process itself,
including preparation, detection analysis, containment,
eradication, recovery, and lessons learned.
Next, we'll take a look at threat hunting.
Now, threat hunting is a proactive cybersecurity approach
involving the continuous search
and identification of hitting or emerging threats
within an organization's network and systems.
Then we'll discuss the concept of a root cause analysis.
Now, a root cause analysis is a systematic process used
to investigate incidents and identify the underlying factors
or events that led to a security breach
or operational issue.
After that, we will look
at incidents response training and testing.
Incident response training and testing
involves preparing personnel and systems
to effectively respond to security incidents
through table talk exercises,
simulations, drills, and lab exercises.
Next, we'll explore some digital forensic procedures.
These digital forensic procedures refer
to the systematic techniques
and methodologies used to gather, analyze,
and preserve digital evidence
for investigations into cyber crimes or security incidents.
Then we'll review data collection procedures
that you can use during an incident response.
Data collection procedures are established methods
for gathering relevant information and evidence
during an incident response for forensic investigation,
as well as covering a concept known as order of volatility.
After that, we'll look at how disk imaging
and analysis is performed during an incident response.
Disk imaging and analysis
involves creating a bit-by-bit copy
or image of a storage device or disk,
and then examining the contents to recover data,
investigate incidents, or identify security issues.
And finally, we'll take a short quiz to see what you learned
during this section of the course,
and review each of those quiz questions to fully ensure
that you can explain why each answer was right.
So, let's prepare for the inevitable by learning
about the incident response process
in this section of the course.
