Tutorial / Cram Notes
AWS operates under a shared responsibility model where AWS is responsible for protecting the infrastructure that runs AWS services, and AWS customers are responsible for securing their own data and applications that utilize AWS services.
Roles in an Incident Response Plan
An effective incident response plan requires a clear definition of roles and responsibilities. The key roles generally include:
- Incident Response Manager: This individual leads and coordinates the response to an incident and is responsible for the overall management of the incident response process.
- Security Analysts: Team members who are tasked with identifying and analyzing security threats. They may be divided into tiers, with each tier having specific responsibilities. For example, Tier 1 may handle initial alerts and Tier 2 may perform deeper analysis.
- Threat Researchers: Specialists who stay informed about the latest cybersecurity threats and advise the team on the specifics of any threats encountered during an incident.
- IT and DevOps Engineers: These individuals maintain the systems and software that are involved in the incident and may be tasked with applying patches, changing configurations, or performing other technical tasks to resolve the incident.
- Legal and Compliance Officers: Responsible for ensuring that the incident response follows all relevant laws and regulations. This may also involve communicating with outside parties, such as law enforcement or regulatory bodies.
- Communication/PR Specialists: These team members manage communications both within the organization and externally, such as to customers or the public, concerning the nature of the incident and how it is being addressed.
- Human Resources: They may be involved to address any internal personnel issues that arise as a result of the incident.
