The achievment is self-explanatory for completing all MP maps on Gold. There are 6 maps, simply survive all 10 waves (and extract) on all of the on Gold difficulty.

In order to get this in SP, you need to complete all unique missions on Insanity (best done when doing your Insanity run). These are the missions where you land on a planet/space station, do something and leave. The random fetch quests for Citadel people do not count.

As per the in-game achievement tracker, there are 27 such missions. As far as I know they are as follows:

All Priority missions (story related and unmissable). 13/27.
- Earth
- Mars
- Palaven (Menae)
- Sur'Kesh
- Tuchanka
- Citadel (Cerberus)
- Geth Dreadnought
- Rannoch
- Thessia
- Sanctuary
- Cerberus Headquarters
- Earth Return
- Citadel Finale

All other planetary missions. For safety, do these BEFORE doing the Priority mission. 17/27.
- Tuchanka: Turian Platoon
- Tuchanka: Bomb
- Rannoch: Rescue Admiral Koris
- Rannoch: Geth Fighter Squadrons

All N7 Missions (6 of them). 23/27.
- N7: Cerberus Lab
- N7: Cerberus Attack
- N7: Cerberus Abductions
- N7: Cerberus Fighter Base
- N7: Fuel Reactors
- N7: Communication Hub

Miscallaneous. 27/27.
- Grissom Academy: Emergency Evacuation
- Attican Traverse: The Rachni
- Kallini: Ardat-Yakshi Monastery
- Arrae: Ex-Cerberus Scientists

Eden Prime (from the From Ashes DLC) is not required for this achievement.

Note that both Grissom Academy and Tuchanka: Bomb are missable if you do not do them within three missions of receiving them. Do them ASAP. Thanks to Pyro1099 and Kennyannydenny in the comments for the intel on these.

In addition, you can obtain these across saves (you could, for example, miss Grissom Academy, reload a previous save and do the mission for the achievement progression to register). Thanks to Tony Starc in the comments for the confirmation of this fact.

As far as I am aware, these are the missions that must be completed on Insanity. You can keep track via the Achievements tracker on the Main Menu (there will a bar with #/27 completed).

If I missed anything, left anything out please let me know in the comments. Good Luck!
