This domain focuses on the security specialist’s responsibility in incident response. Everything from incident response to disaster recovery and business continuity is covered in this domain. Both technical and administrative subjects are included in the examination. It not only includes forensics, network reconnaissance, and discovery ideas, and the capacity to configure systems for incident mitigation, but it also includes the planning phase, which includes everything from tabletop exercises and simulations to the development of strategies. This domain covers 16% of weightage in the examination.

includes everything from tabletop exercises and simulations to the
development of strategies. This domain covers 16% of weightage in
the examination.
The topics covered in security+ domain 4.0 are listed below:
1. Given a scenario, use the appropriate tool to assess organizational security
2. Summarize the importance of policies, processes, and procedures for incident
response
3. Given an incident, utilize appropriate data sources to support an investigation
4. Given an incident, apply mitigation techniques or controls to secure an environment
5. Explain the key aspects of digital forensics

Explain the key aspects
of digital forensics
05
Whereas incident response focuses on eradicating malicious
activity as soon as possible, digital forensics needs patient
acquisition, preservation, and examination of evidence using
verified methodologies. In this subdomain, we will learn basic
concepts of digital forensics, explain documentation, evidence,
and admissibility. Inside this we will cover the following subtopics
We understand E-discovery, Preservation, Data recovery, Non-
repudiation, Strategic intelligence/counterintelligence. We will get
familiar with Data Acquisition and subtopics like Order of volatility,
Disk, Random-access memory (RAM), Swap/pagefile, OS, Device,
Firmware, Network, Artifacts. Concept of on-premises vs cloud,
Right to audit clauses, Regulation/jurisdiction, Data breach
notification laws. We will also cover Integrity, Hashing, Checksums,
