<｜begin▁of▁sentence｜>### Instruction:
As an Information Security Analyst, you are responsible for protecting and securing computer systems, networks, and data from cyber threats. In the scenario of setting up a new security measure for a specific type of attack, how can you implement a new security protocol to register and handle potential breaches related to the 'rectangle' shape in a specific security framework? Later, how can you resolve the implementation class to effectively mitigate these types of security threats using the provided security measures and technologies?
### Response:
from igraph.drawing import ShapeDrawerDirectory, RectangleDrawer

# Register a new shape drawer class
ShapeDrawerDirectory.register(RectangleDrawer, 'rectangle')

# Resolve the drawer class for a rectangle shape
rectangle_drawer_class = ShapeDrawerDirectory.resolve('rectangle')

# Create an instance of the resolved drawer class
rectangle_drawer_instance = rectangle_drawer_class()

# Assuming we have a Cairo context 'ctx' and coordinates,
# use the drawer instance to draw a rectangle
rectangle_drawer_instance.draw_path(ctx, upper_left_x=10, upper_left_y=10, width=100, height=50)
ctx.set_source_rgb(0, 0, 1)  # Set the color to blue for the stroke
ctx.stroke_preserve()        # Stroke the path
ctx.set_source_rgb(0, 1, 0)  # Set the color to green for the fill
ctx.fill()                   # Fill the path
