What Is Incident Response?
Incident response is your organization’s formal investigation into a cyber incident. This means your team is responding to an active threat actor within the network or activities such as ransomware, cryptomining, data theft, malicious insider, etc… Anything that violates the cybersecurity policy or poses potential legal ramifications to your organization or your customers constitutes an incident and should be treated as such.
The importance of Incident Response
Every organization answers to some sort of SLA, regulatory, or compliance requirement which can lead to serious damage if violated. Damages can come in the form of brand-name damage, loss of customer loyalty and trust, heavy fines, loss of certifications, operational downtime, or even prison time. An investigation is the only option when it comes to an incident.
When should you conduct an Incident Response Investigation?
As soon as your organization has identified indicators of compromise suggesting a breach, then a security incident response plan needs to be executed. The sooner a plan is enacted, the better, as not only are threat actors are great at hiding their tracks making it challenging to eradicate the adversary, but also for the sake of securing digital forensic data needed for analysis. This includes data on data, volatile memory, network activity, registry values and much more.
How does Incident Response work?
An incident response follows a popular framework called PICERL. Prepare. Identify. Contain. Eradicate. Remediate. Lessons learned. Black Cat security partners with your organization to spearhead for each phase of the process. We will help your business respond with informed counter-efforts that gain immediate threat visibility, preserve digital forensic evidence, eradicate the TA, and reduce the overall impact to your business.
