Business continuity ensures that business processes can continue despite interruptions. Continuity of operations (COOP), disaster recovery plans (DRPs), as well as hot, warm, and cold alternate sites are discussed.
Gathering digital evidence

Stepping through how attackers manage to compromise a system or exfiltrate data helps harden environments to prevent future incidents. This episode covers the Cyber Kill Chain, the Mitre ATT&CK Framework, the Diamond Model of Intrusion Analysis, and how Security Orchestration, Automation, and Response (SOAR) tools can reduce incident response time.
Incident Response Plans (IRPs)

An IRP provides guidance on how security incidents are dealt with effectively while they are occurring. The IRP includes roles, responsibilities, a contact list and escalation procedures. IRPs should be updated periodically through lessons learned from past incidents.

Responding to incidents in a timely and effective manner is the result of proactive planning with defined roles and responsibilities.
Security+ - Network Security and Diagnostics
Lab - 00:30:00
A layered approach must be designed and implemented to secure a system or infrastructure. Each critical component should be individually assessed on the risks it faces. In all scenarios, for all types of systems, network security is always a crucial component. Being the backbone of communication and the carrier of sensitive and proprietary information, once compromised, it allows unauthorized parties access on a large scale.
