3. Provided that personal data are protected in accordance with applicable Union data protection law, CERT-EU shall, without undue delay, exchange relevant incident-specific information with Member State counterparts to facilitate detection of similar cyber threats or incidents, or to contribute to the analysis of an incident, without the authorisation of the Union entity affected. CERT-EU shall exchange incident-specific information which reveals the identity of the target of the incident only in the event of one of the following:
|
(a)
|
the Union entity affected consents;
|
|
(b)
|
the Union entity affected does not consent as provided for in point (a) but the disclosure of the identity of the Union entity affected would increase the probability that incidents elsewhere would be avoided or mitigated;
|
|
(c)
|
the Union entity affected has already made public that it was affected.
|
Decisions to exchange incident-specific information which reveals the identity of the target of the incident pursuant to the first subparagraph, point (b), shall be endorsed by the Head of CERT-EU. Prior to issuing such a decision, CERT-EU shall contact the Union entity affected in writing, explaining clearly how the disclosure of its identity would help to avoid or mitigate incidents elsewhere. The Head of CERT-EU shall provide the explanation and explicitly request the Union entity to state whether it consents within a set timeframe. The Head of CERT-EU shall also inform the Union entity that, in light of the explanation provided, he or she reserves the right to disclose the information even in the absence of consent. The Union entity affected shall be informed before the information is disclosed.
