Asset Protection is one of the Security Contracts added as part of the Contract DLC in GTA Online.
You need to go to the marked location and protect the client's assets. There will be a lot of enemies trying to destroy it, and you need to protect the assets from incoming enemies.
We recommend that you use an Armored Kuruma and stock up on armor and snacks, just in case. But realistically, if you're inside the Armored Kuruma, you won't need a lot of snacks and armor.
When you start the mission, a 10-minute timer will start at the bottom-right corner of your screen. This is the total time you get to get to the location and protect the asset. You need to protect the asset until this timer runs out.
When you get to the location, stay inside the Armored Kuruma and eliminate the incoming enemies. You will also have some help from the ally NPCs, so don't worry too much if you're doing it solo.
The enemies will spawn in waves, and they will increase in number as you plow through the waves. Take special care of the enemies with a flame icon on the mini-map.
These enemies have a Molotov, and they can do a lot of damage to the assets. They throw the Molotov and damage the targeted asset and the surrounding assets. Make the Molotov enemies your priority and take them out before dealing with other incoming enemies.
Once the timer nears the end, the enemies will stop spawning, and more backup will arrive. At this point, you've successfully completed the Security Contract mission.
After protecting the important assets, you can return to the main hub to learn how to complete other Security Contract missions.
