Network architecture – Security threat

Slide Content

The slide presents a schematic visualization of a network security threat, specifically focusing on the challenges posed by both direct attacks and hidden malware. "My company’s network" represents the internal network, where computers are protected by a firewall that prevents attacks and filters out malicious content. "Direct attack" indicates an immediate threat targeting the network, while "Hidden malware" suggests the risk of compromised software within the network. "Threat source" consists of various technologies which could be vectors of cyber attacks. "Customers and services from outside world" imply interactions with external entities that could introduce risks. A cautionary note states "An infected device is brought behind the firewall," highlighting a common security breach scenario where a compromised device within the network's perimeter bypasses the firewall's protection.

Graphical Look

• The slide has a dark blue background with a large, lighter blue, curved shape on the left side.
• A red banner is placed at the top of the slide with the title text in white.
• Two main sections are visually divided by color: the left side representing the company's network is in blue, and the right side representing external threats and services in lighter blue with cloud icons.
• Computer icons in both sections are illustrated with green arrows pointing towards a central firewall icon and red arrows pointing away from threat sources.
• The firewall is shown as a central hub with a shield icon, emphasizing its protective role.
• Icons representing various technology devices are arrayed around the threat source area, suggesting multiple points of vulnerability.
• There is a red-bordered caution sign with white text at the bottom left, drawing attention to the critical note about the infected device.

The slide uses contrasting colors, arrows, and icons to visually represent the flow of information and potential security threats within a network. It provides a clear distinction between the protected internal network and the external threat sources.

Use Cases

• To educate employees or stakeholders about network security vulnerabilities and the importance of a strong defense system.
• During a cybersecurity training session, explaining how security threats can infiltrate a network and the mechanisms of firewall protection.
• As part of an IT security assessment presentation to highlight potential risks and the paths that malware might take to compromise network integrity.
• In a proposal for cybersecurity solutions or investments, illustrating the need for robust protection against both direct attacks and hidden malware.
