Dynamic Network Security States for Layered Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer network security measures are static and unable to dynamically adjust protection levels in response to user needs or system requirements, leaving networks vulnerable to attacks.
Innovation Solution
A computer security mechanism that employs multiple security states with transitions based on specified conditions or events, allowing successively increased levels of network access, including disabling all network access initially, then allowing outbound connections, local inbound connections, remote connections, and finally authenticated connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static firewalls and security measures are used, then network security is maintained at a fixed level, but the system cannot dynamically adapt to changing user needs or attack conditions
Solution Approach 1:
The patent implements dynamic security states that can transition between different levels of network access based on real-time conditions. The system moves from a static firewall approach to a dynamic state machine that adjusts security parameters automatically, allowing the network to adapt its security posture in response to user actions, network conditions, and detected threats.
Solution Approach 2:
The system changes security parameters by transitioning between multiple defined security states (e.g., state 1: no network access, state 2: outbound only, state 3: local inbound allowed, state 4: remote inbound allowed). Each state is characterized by different parameter settings for network access control, enabling flexible adaptation without compromising security reliability.
2Adaptability or versatility
If multiple security states with transitions are implemented, then dynamic security adjustment is achieved, but the system complexity increases
Solution Approach 1:
The security mechanism is segmented into discrete, manageable security states (state 1 through state 4 in the patent) with clearly defined transition conditions. This segmentation breaks down the complex security control into manageable components, making the system more implementable while maintaining flexibility. Each state is a distinct configuration with specific access rules.
Solution Approach 2:
The patent uses a state machine approach where security transitions are triggered by specific events or conditions. This dynamic structure provides flexibility through multiple states while managing complexity through event-driven transitions rather than continuous monitoring and adjustment.
3Object-affected harmful factors
If network access is completely disabled, then security against unauthorized access is maximized, but legitimate user needs for network communication are blocked
Solution Approach 1:
The system dynamically adjusts network access based on user needs and security conditions. Instead of a fixed blocked state, the system can transition to allowed states when legitimate communication is detected or authorized, balancing security with usability.
Solution Approach 2:
The security system incorporates feedback mechanisms that monitor network activity and user actions. When legitimate communication patterns are detected, the system responds by transitioning to more permissive security states, allowing network access while maintaining protection against unauthorized access.

AI summary
Techniques and systems for computer network security are described. One example system includes a computer security mechanism based on multiple security states that each allow successively increased levels of network access, where transitions between the security states occur in response to specified conditions or events. An example system starts (e.g., boots, initializes, powers up) in a first state in which no network communication is allowed. In response to an event such as a user starting a Web browser or other approved program, the system transitions into a second state, in which only outbound network communication is allowed. Thus, in the second state the Web browser can make an outbound request for information but any inbound connection requests will be rejected. In response to other events, the system transitions to security states that allow successively higher levels of network communication.
