How can you verify the authenticity of software being installed?

1. Check the software's user reviews

2. Look for code signing

3. Download from any website

4. Use software without confirmation

The correct answer is: Look for code signing

Verifying the authenticity of software being installed is crucial to ensure it is legitimate and has not been tampered with. Looking for code signing is a reliable method for this verification. Code signing is a security measure that involves a cryptographic signature, which is applied to the software by its publisher. This signature helps to confirm that the software has not been altered since it was signed and that it comes from a verified source. When software is code signed, the operating system can check the validity of the signature when the software is run. If the signature is intact and matches the trusted publisher, this indicates that the software is authentic. It is a robust mechanism to safeguard against the risks of malware and counterfeit software. The other choices do not provide a reliable method for verifying software authenticity. User reviews can be manipulated and do not guarantee safety or legitimacy. Downloading from any website, especially untrusted ones, poses a significant risk as such software may contain malware. Using software without any confirmation entails a lack of due diligence, which can lead to substantial vulnerabilities in a system. Thus, relying on code signing stands out as a secure method for authenticating software.
