The fundamental imbalance in such an arms race is that the tech giant might have countermeasures that would prevent the SSH alias from working (my team does), but the level of paranoia required to get those countermeasures in place is beyond what a bank could effectively implement. This particular battle disproportionately favors the red team.
And that's not to say that my team has everything covered. The red team consistently manages to find forehead slapping holes in our defenses. There's just too much surface area to cover.
