NIST defines an incident as a violation of cybersecurity policies or standard security practices, such as the use of a botnet to send massive traffic to cause a denial of service, obtaining sensitive data to demand a ransom to return it, or tricking users to open phishing emails to spread malware. Currently, there are numerous attacks that compromise personal and business data.
If a business fails to properly mitigate incoming cyber threats, chances are that a security breach might occur. Presently, hackers have advanced and are capable of launching sophisticated attacks that can lead to loss of financial resources, compliance suits, and reputational damage. In effect, it is necessary for enterprises to develop and implement quality incident response plans that respond quickly and effectively in case of a breach.
NIST guides businesses in organizing an effective incident response capability that involves critical actions and decision.
The first consideration involves creating a specific definition of the term “incident” in an organization to ensure that the term’s scope is clear. Secondly, an incident response plan should be defined to support systematic and consistent handling of attacks. It is vital to have a series of phases in the incident response, such as preparation, detection, containment, eradication, recovery, and post-incident tasks.
Overall, an incident response plan inspired by NIST guidelines can help minimize loss of information or disruption of services that are caused when data breaches occur. Moreover, an incident plan offers the ability to document and use outcomes gained while handling an incident to enhance the response plan for future incidents and for improving the security of information and systems. At the same time, a proper incident response plan is necessary for appropriately dealing with legal and compliance issues that might arise while handling an incident.
In conclusion, it is a good start for organizations to use NIST guidelines and framework as a reference point while creating an incident response plan to be used in an environment where attacks are continuously raising.
The incident response can be planned into phases that guide in incident handling and determining an appropriate response to the incidents.
