Simply complete the ViewPoint Museum mission. It's in the lower east side of Federal Triangle right before DZ East.
At low-level, this is actually a pretty hard mission. The hardest part is near the end as you can't use skills because of 3x Skill jammers, you need to shoot these puppies out asap. If you're in a squad have 3x on crowd control and 1x knocking out the three jammers. Now you can use your skills, and it's much easier.
