Methods and systems for securing data processing systems are disclosed. A data processing system may be operably connected to other devices via ports. When operably connected, some devices connected via the ports may cause undesired actions to be performed. To limit physical access to the ports, a security apparatus may be used to lock the ports. The security apparatus may transition between states where it may be inserted into openings for the ports and may be locked to the openings for the ports. When so locked, physical access to the ports may be limited.
