Execution Isolation
Definition
This technique is to prevent unauthorized access and ensuring that system stability and security are maintained.
By isolating processes and restricting their access to only necessary resources, these techniques help mitigate
the risks of security breaches, resource conflicts, and system instability.
How it works
Execution isolation works by creating boundaries between different parts of a system (such as processes,
applications, or services) to ensure that they operate independently. This independence is crucial for
preventing interference, whether accidental or malicious, between these parts.
In robotics
Execution isolation in robotics, particularly as a measure to protect against attackers, involves creating
distinct and separate operational environments within a robot's system to enhance its security. This concept is
crucial in preventing unauthorized access or control and ensuring that the robot remains safe and functional
even in the presence of potential threats.
Considerations
- Classification: By isolating different functions or processes, a breach in one area doesn't necessarily
compromise the entire system. For example, if an attacker gains access to a robot's sensory data
processing,
they still might not be able to control its movement if these functions are isolated.
- Limited Access and Privileges: Execution isolation often involves implementing varying levels of access
and
privileges for different processes. This means that even if an attacker compromises one process, they
can't
necessarily leverage it to gain broader system access.
- Reduction of Attack Surface: By isolating systems, the attack surface (the number of potential points of
entry
for an attacker) is reduced. Each isolated system can be fortified individually, making it harder for
attackers
to find vulnerabilities.
