What is Meltdown and Spectre

Meltdown and Spectre are two major security issues. They impact Intel, ARM and AMD computer chips, Meltdown and Spectre work on personal computers, mobile devices, and in the cloud. They are attack on our computer and break our security. They are different from each one.

Meltdown:-The easier and more serious vulnerability. The ‘Meltdown’ exploits breaks down CPU-level Protections and allows a program to access memory.

 Spectre:-Spectre breaks the isolation between different applications. It allows an attacker to trick error-free programs, which follow best practices, into leaking their secrets.

So what we can do for safety

Microsoft says it released a security update Wednesday to help mitigate the issue. If you're running Windows 10, it should automatically download and install -- but it might depend on your PC's settings. According to Google, a new security update dated Jan. 5 will include "mitigations" to help protect your phone, and future updates will include more such fixes.
So you have to update your mobile phones and laptop. But biggest problem is that what will happen to those devices which are not getting software updates.
