1SPECTRE, MELTDOWN, COUNTERMEASURES AND FUTURE IMPACTExecutive SummaryThis report discusses about the Meldown and Spectre attack following with the table thatdifferentiate between the two attacks. The critical analysis of both the attacks has been providedthat has identified several factors for this attack. In the later section, counter measures of thevulnerabilities have been discussed and the process of fixing those vulnerabilities. Finallyprovide the future impact of the Meltdown and Spectre vulnerabilities.

3SPECTRE, MELTDOWN, COUNTERMEASURES AND FUTURE IMPACTIntroductionThe study will be about the Meltdown and Spectre attack and provide detail informationabout the vulnerabilities and software patches done by these attacks. The study has analysed thatisolation is the basic computer premises for security. As machines of Kernel are the most innersanctum that has access to the memory in the computer, it has some bug that allows low-privilege process to access the Kernel memory of the computer. The study has also revealed theinformation about the malicious software attack that has done through Meltdown and the datastolen by the Spectre. Finally, the study had discussed about the future impact of Meltdown andSpectre.SpectreSpectre can break down the isolation between different applications. It helps attackers toget an error-free program to leak secret information (Kocher et al. 2018). The safety checksincrease the attack on the surface that makes applications to be more susceptible to Spectre. Thepatches of Spectre reported to significantly reduce the performance on the old computers and tonew Core platforms of eight-generation. The vulnerability of Spectre affects the modernmicroprocessor through which the branch prediction performed. The attackers can extractinformation from the private data by using the timing attack that has affected the processor ofspeculative execution which has resulted from the branch misprediction (Arondekar and Patel2016). The data stored on another website or the browser's memory can be read easily by aparticular website. The attackers may be able to read the memory content that they have access,and thus some sensitive data are potentially achieved.
