A minimalist vector diagram of an abstract execution flow graph with nodes and paths, including bug and code shield icons.

A clean, minimalist academic thesis cover illustration focused on computer systems security and Control Flow Integrity (CFI). The image depicts an abstract execution flow graph with clearly structured nodes and edges, symbolizing control-flow paths being strictly constrained and validated. The logos of the two tools are attached. Certain paths are highlighted or enclosed to convey enforcement and integrity, while forbidden paths fade out or terminate abruptly. Two small, subtle tool logos are integrated naturally into the composition, placed symmetrically near the lower half of the image, rendered as monochrome or low-contrast line icons so they do not dominate the design. The visual style is modern, restrained, and professional, suitable for a PhD dissertation cover. Flat design, vector-like clarity, no text, no characters, no clutter. Color palette limited to deep blue, muted gray, and off-white, evoking trust, rigor, and technical depth. Soft lighting, high contrast, and strong negative space to allow overlaid title and author text. See more
