Sorting Out Security: Making Sense of Today's Solutions
Security at the process level is essential to creating an immunity to the cyberattacks of tomorrow.
Embedded Devices Need Embedded Security
Von Neumann's architecture doesn't account for the additional information a processor needs to ensure that it does only what the application designer intended. Processors will blindly execute the instructions they receive, and they have no way of knowing whether an instruction came from a trusted source or a malicious attacker.
Complex software will always have exploitable bugs because software is written by humans—and humans make mistakes. Our processors need computing security. They need to be modified to make them immune to attacks that prey on software vulnerabilities. They need to be given the intelligence to distinguish between good and bad instructions, and the ability to stop malicious instructions at the processor level before any damage can be done.
The Bottom Line
We need to secure our communications, so people can't siphon off corporate or national secrets, or steal identities and other personally identifiable information. Communications security is accomplished by using well-established cryptographic algorithms to encrypt and decrypt communications. We also need to secure our computing devices to protect against the inevitable and unavoidable vulnerabilities in software that enable attackers to hijack processors. That's computing security. As Larry Ellison, Oracle's CTO and chairman, noted, "Even the best hackers have not figured out a way to download changes to your microprocessor… You can't alter the silicon."
Security at the process level—and the systems in which it is embedded—is essential to creating an immunity to the cyberattacks of tomorrow.
