| 1 | + | Every piece of code may contain viruses, spyware, trojan horses, backdoors, rootkits, keyloggers and other kinds of malware. The risk has dramatically increased with the advent of wide-area networks like the internet, where it is easy to download programs of unknown or unverified origin. | |

| 3 | + | One measure to reduce the effects of malicious code is that some modern operating systems require executables and scripts that have been downloaded from the internet to be signed with a developer's certificate. Code signing confirms the identity of the software author and guarantees that the code has not been altered or corrupted since it was signed by use of a cryptographic hash. Therefore, it ensures both authenticity and integrity of the executables. | |
