The complete term that we are talking about here is called Digital Forensics and Incident Response
. It is also commonly called a Digital Forensics Incident
. In a world like today when the internet has become a common thing and almost every work depends on it. Such a situation demands tight security measures in order to save your resources that take help from digital media. Threats are increasing day by day. Things like ransomware, phishing, and other attacks have become far too common. But you can keep yourself and your resources safe through awareness and proper measures.
Some Fundamentals of Digital Forensics
It is a special category that generally belongs to cybersecurity in computer science. It is widely used for examining the digital components of resources related to computers. That examination is done mainly to check the occurrence of illegal activities against the organization or firm. In case, anything illegal happens to the firm, it is checked whether the owner was responsible for that or someone else.
In most cases, the professionals involved here examine the hard disks and other computing devices. But that examination is not enough in this highly modern world of the internet. So, digital forensics also analyzes all the digital properties like computer networks, digital assets, memory, and several other things. The other part of this process called incident response. The incident response is a set of processes that occur after the identification of the incident.
This process starts by informing all the parties involved in this process. Equal participation of all the parties leads to the proper flow of information and the steps required to resolve this issue are identified in the proper duration of time. In most cases, malware analysis is performed as a part of the incident forensics. Reverse engineering the malware may help you know about the way software operates. With this process, the software engineers also get some idea about the producers and the other people associated with this incident.
How is it done?
Now that you are aware of the fundamentals, let us get some information about how to go on with this process. There are six steps involved in this process. We are going to discuss all those steps in brief here.
- Preparation: At first, the firms should be well prepared to handle these incidents. They should have proper policies and should hire incident managers for more convenience.
- Identification: Here the professionals identify the threat, its type, and the risks involved here. This process gives the professionals insight into the way this attack was done and other critical things.
- Containing and correcting the issue: Once the issue has been identified, all the professionals try to stop it from further spreading. After successfully containing the issue, proper steps are taken to correct this situation.
- Recovery and reporting: Now that the issue has been resolved, the company works on getting to its regular operational state. After everything has got on track, the issue is reported to the specified people.
