Create a simplistic cartoon-style design for a cyber security concept. The design should feature a friendly, cartoonish character representing a security guard or a shield. Use a vibrant color palette with shades like blue, green, and orange to evoke a sense of trust and protection. Incorporate elements like a shield, a lock, or a computer screen with a padlock icon. The character should have a reassuring expression and be depicted in a dynamic, protective pose, such as holding up a shield or checking a lock. The background should be clean and minimalistic, with subtle tech-themed patterns or icons to emphasize the cyber security theme. The overall style should be engaging, approachable, and convey a sense of safety and reliability.
