This allows them to update their risk profiles, such as identifying if their systems are vulnerable. In order to determine what the risk to an organisation is, you need to know what the problems could be. In this assignment, your task is to identify a recently announced security vulnerability and write a profile of the threat. The profile should contain the name of the threat, the systems it attacks, how it performs its attack, mitigation strategies and concluding reflection (100 words) on the adequacy of the mitigation strategies. The risk to an organisation using vulnerable systems should also be determined. Your report should be maximum 2 pages and should contain relevant tables, calculations, a ranked list of threats (in terms of impact) and conclusions.

You should pair up with one of your class fellow to do this lab and record results and give commentary on the results. If you do not have a class fellow then create two user accounts and you can encrypt using one account and descript using other account. a)Generate keys of 2 different sizes for RSA encryption scheme and include these keys in the report. b)Check the key files and estimate the number of decimal digits of the keys and write your estimates. c)Encrypt a file (text or binary) using 2 key sizes and include your results and note the observation d)Explain why GPG encryption and decryption are quite fast. e)Create a file of close to 1 GB and encrypt and decrypt it and note the time taken. Comment on the reason why this much time has taken. Calculate how long it would take to do the encryption/decryption of a 10 GBs of data. f)Export your public key and discuss the reason why your exported key should be in ASCII format. g)Encrypt a file and output the cipher text in ASCII format.
