In this module,we will discuss networkforensics. We move away from cellular/smartphonediscovery and look at wired and wireless investigation. We will use the European Union Agency for CybersecuritysIntroduction to Network Forensicsguide. The document is availableat:https://www.enisa.europa.eu/topics/trainings-for-cybersecurity-specialists/online-training-material/documents/introduction-to-network-forensics-handbook.pdfFor the discussion, answer the following questions:1) What types of network investigations are typical of those that fall under thetopic ofnetwork forsensics?2) How is informationacquired from the various types of networks?3) Describe several tools for network forensics and how the tools function?
Obtain the general solution of the following DEs: i. y′′′ + y′′ − 4y′ + 2y = 0 ii. y(4) + 4y(2) = 0 iii. x(x − 2)y′′ + 2(x − 1)y′ − 2y = 0; use y1 = (1 − x) iv. y′′ − 4y = sin2(x) v. y′′ − 4y′ + 3y = x ; use y1 = e3x vi. y′′ + 5y′ + 6y = e2xcos(x) vii. y′′ + y = sec(x) tan(x)
