So the answer seems to be (and admittedly we speak here of matters which we can currently only 'see through a glass darkly,' as Paul wrote), that Satan can no longer get such close access to God as he had once enjoyed; he had enjoyed certain rights as ruler of this world, but he is dethroned in Christ. This suggests that it is now harder, or even completely impossible, for Satan to actively accuse the brethren before God's throne in Heaven. He now appears to be restricted to roaming the earth, looking for the weaker members of God's flock whom he can entice into sin. See Ephesians 6:10-18...."
