firewall
A self-proclaimed sentinel of good and evil erected on the invisible border of networks, in reality furnishing endless loopholes under the guise of misconfiguration. It flings its gates wide for high-privilege packets, yet mercilessly blocks the lowly. It serves as a shield for administrator negligence, sealing anomalies in cryptic logs that are promptly ignored. When forgotten in good health, it is instantly scapegoated at the first sign of trouble—the unfortunate guardian of the IT realm.
