Who enforces it
Enforcement body
Vatican City State's ordinary criminal justice system; the base offence proceeds only on the victim's complaint, the aggravated forms and offences against Holy See, State, or public-authority systems on the State's own initiative.
What it makes you log
Logging duty
Articles 158 ter and 158 quater make it an offence to enter or remain in a protected computer or telematic system without right, with higher penalties where an official abuses powers, violence is used, the system or its data is damaged, or the system belongs to the Holy See, the State or another public authority, and to obtain or give out access codes for profit or to cause harm. They impose no duty to create, keep, produce or review a log or record and state no territorial clause, so no hook is recorded. Article 18 of the same Law inserts articles 259 bis to 259 decies into the Code of Criminal Procedure, under which the public prosecutor keeps a reserved register of interception orders and the intercepted communications are recorded and kept until the judgment is final; those duties fall on the prosecutor, sit outside the two articles the row cites, and are not borrowed.

What this law does
Legge N. DXXXI of amended Vatican City State's Penal Code, entering into force on (art. 31).
New article 158 ter punishes whoever abusively enters a computer or telematic system protected by security measures, or remains in it against the express or implied will of the person entitled to exclude them, with up to three years' imprisonment; the penalty rises to one to five years where a public official or a person entrusted with a public service commits the offence abusing their powers or duties, or with violence to persons or property, or where the offence causes destruction or damage to the system or an interruption of its operation, or destruction or damage to the data, information, or programs it holds; and it rises further, to three to eight years, where the system belongs to the Holy See, Vatican City State, or another public authority.
The base offence is prosecuted only on the victim's complaint; the aggravated forms proceed on the State's own initiative.
New article 158 quater punishes whoever, to gain a profit or cause harm, abusively procures, reproduces, disseminates, communicates, or supplies passwords, access codes, or other means suited to accessing a protected computer or telematic system, or otherwise supplies instructions for that purpose, with up to one year's imprisonment; this offence too is prosecutable only on complaint where the system belongs to a private party.
Neither provision addresses the status of a public, unauthenticated page carrying no security measure, and no reported Vatican City State case construes either article.
