How to Protect Your Mobile Devices from the Meltdown and Spectre CPU Security Flaws?

If you’re constantly updated about the IT world, then you must have heard about the Meltdown and Spectre CPU security flaws making rounds on the internet.

These two major processor security flaws emerged this week and have sent the IT world into a frenzy.

The IT industry has gotten together to fix these issues and secure the devices for customers.

Meltdown and Spectre CPU Security Flaws

Found in a number of processors from the ARM, AMD, and Intel, Spectre, and Meltdown are the two security flaws that could allow hackers to access encryption keys, passwords, and other private and confidential information from open applications.

These security flaws are sending shock waves through the entire IT industry. One of the members of Google’s Project Zero found out these flaws along with other people.

To be specific, it was revealed that these flaws had been present in the chip designs for over twenty years, affecting a number of companies’ processors. That indicates that the flaws could be found on a large number of devices including PCS, web servers, and mobile devices.

The Current Situation

As far as the current scenario is concerned, users shouldn’t panic much because so far, these Meltdown and Spectre CPU security flaws have not been used in an attack. Device manufacturers have already started working with the ARM, AMD, and Intel to fix these issues.

In fact, Intel has gone on to claim that these exploits cannot modify, corrupt, or erase the data. However, Spectre security flaw may need a processor redesign to get it fixed.

The future processors should be free from these security flaws. As a user, you need to keep a constant eye on any updates your mobile device offers and also follow our guide to understand how you can protect your device against these security flaws.
