What is the best protection against Coronal Mass Ejections from the sun?

Every week or so, there are CMEs that typically don't even approach Earth, but when they do, they essentially behave like EMPs, damaging Earth's magnetic field and frying circuit boards and other electronics.

As of right now, "[a] direct hit from a very large CME is a one-in-100-year event according to solar research at NASA and the European Space Agency." 1 Earth's magnetosphere is extremely weak, and CMEs from the sun can reach diameters of well over 45 million miles and travel at speeds of millions of miles per hour.

To put it mildly, we must act quickly to determine how to safeguard Earth.

Strong space weather monitoring systems, which include early warning systems capable of detecting and tracking CMEs as they approach Earth, are the best defense against Coronal Mass Ejections (CMEs) from the Sun. Moreover, spacecraft and satellites in Earth's orbit can be outfitted with shielding and redundancy systems to reduce the impact of CMEs on their electronics and systems. On Earth, protective measures can include fortifying power grids and communication networks to lessen the likelihood of damage from CME-induced geomagnetic storms.
