Cyberattacks can affect any organization's system
or network. The process used by an organization
to respond to and manage a cyberattack is known
as incident response. It helps you keep track of
security incidents, analyze and contain risks,
and remove them from your network.

Incident Response Plan (IRP) An Incident Response
Plan (IRP) is a structured series of stages that
must be followed to ensure that every part of a
cyber incident is investigated and documented.
The tricky part is to determine which business
components are most beneficial to produce the
most productive IRP. You have a good chance of
defending against these types of attacks and
designing an IRP to best suit the firm's
environment if you can identify where a company
is most likely to be targeted.

• Cybersecurity Incident Response Steps
• The following are the defined steps that should
  be included in every cybersecurity IRP
• Preparation Preparation is the first and
  essential step in responding to cybersecurity
  incidents. You will require a solid plan in place
  to help your incident response team, as, without
  it, even the strongest team will be unable to
  resolve a cyber incident successfully. Teams must
  establish policies, procedures, and agreements
  for incident response management, create
  standards for smooth communication, access their
  threat detection capabilities, and more to
  adequately address security incidents.

Identification It is critical to have a proper
setup to recognize when an incident has occurred.
This is usually where intrusion detection system
alerts appear. Web filtering gateways detect
suspicious external connections. SIEM solutions
connect the dots between an attacker passing
through the internal network and an endpoint
solution detecting the opening of a phishing
email. In any case, qualified security personnel
must act quickly to escalate and respond to the
alerts. Containment After an incident has been
identified, the threats must be contained. This
phase aims to contain the damage and use
containment strategies to prevent it from getting
worse. It is one of the crucial steps of incident
response. Eradication Eradication is one of the
most challenging stages of the incident response
process because it requires forensic analysis to
identify the extent of the threat actor's
presence. Security professionals must ensure that
whatever they do in the eradication step removes
the threat actor's presence and access to the
system. This entails reimaging systems, looking
for backdoors, and, most importantly, pinpointing
the incident's core cause.

Recovery After eradication, the recovery stage
begins. It is critical at this step to get the
infected systems back up and running to minimize
any potential financial losses related to the
infected system's downtime. Simply, it refers to
the testing of fixes in the eradication phase as
well as the transition to normal
operations. Lessons learned Lessons learned is
also one of the essential stages since it
demonstrates to everyone how the incident
occurred and how efficiently the exploit's attack
vector was closed. The main lessons from this
phase are to improve your incident response
capability and your security footprint.
