CVE-2023-2003

Restricting software to licensed versions and controlling P2P prevents introduction of software containing embedded malicious code from unauthorized sources.

The control prevents users from installing software that contains embedded malicious code.

Regular inventory reviews and updates make it harder to conceal or exploit embedded malicious code by requiring all components to be documented and accounted for.

Reverting to a known state removes any malicious code embedded by an attacker.

The approval and review process for maintenance tools can prevent introduction or continued use of tools containing embedded malicious code.

Supply chain strategy requires vetting and controls during acquisition to prevent or detect insertion of malicious code by vendors or integrators.

Background screening for development or deployment roles makes intentional insertion of malicious code by insiders materially harder to accomplish.

The capability explicitly searches for embedded malicious code and backdoors as indicators of compromise.

Due diligence prior to supplier relationships helps avoid sources of embedded malicious code.

Supplier risk assessment reduces likelihood of receiving products containing malicious code.

Pre-acquisition assessment of critical suppliers mitigates risk of malicious code in procured software.

Requiring suppliers to furnish component lists, attestations, and cryptographic verification of delivered artefacts makes it harder for an attacker to embed hidden malicious code that would otherwise go undetected through the supply chain.

Checks that executed code has not been tampered with and monitoring for malware-associated activity reduce the likelihood that hidden malicious code remains active.
