MEASURES AGAINST SPAM SENDING FROM OVH NETWORK
OVH is implementing a set of technical measures to fight against the sending for fraudulent e-mails as well of SPAM from its infrastructures.
To this end, OVH performs some verification on the traffic sent from the server used by the client to port 25 (SMTP) on the Internet. The traffic is analyzed by automatic tools .
Emails sending are neither filtered nor intercepted but checked with a time lag of a few seconds. These operations are performed in parallel and in sequentially before the emails are sent to the Internet.
Similarly, no operation is performed on the emails sent: OVH does not tag emails, and does not alter in any way the emails sent by the Client. No information is stored by OVH during these operations outside of statistics. This operation is done regularly and is fully automatic. No human intervention is performed when checking traffic to port 25 (SMTP port).
In the case of the emails sent from a Client’s server identified as spam or fraudulent, OVH will inform the Client by email and will block the SMTP server port.
OVH does not retain any copies of emails sent from the SMTP Server even when identified as spam.
The Customer may request the unblocking of the SMTP port through the management interface.
Any new email identified as spam will result in a new blocking of the SMTP port for a longer time.
From the third blocking, OVH reserves the right to refuse any request to unblock the SMTP port.
MITIGATION (PROTECTION FROM DOS AND DDOS ATTACKS)
OVH is implementing a protection against Denial Of Service (DOS) and Distributed Denial Of Service (DDOS) computer attacks and provided when made in a massive way. This feature is intended to prevent the Customer’s operations to be inaccessible during the attack.
This object of this feature is to check the traffic to the Customer’s Service and from outside of the OVH network.
The illegitimate qualified traffic is then rejected upstream in the Client’s infrastructure, allowing legitimate users to access the Service despite the undergoing cyberattack.
These safeguards do not prevent other computer attacks such as SQL injection, bruteforce, security vulnerabilities’ exploitation etc.
Due to the great complexity of this Protection Service, OVH is not subject to an obligation of means; it is possible that the attack is not detected by the tools in place, and that the tools developed do not prevent the operation of the Service to be interrupted.
Depending on the nature of the attack and its complexity, OVH deploys a protection at different levels of traffic to preserve its infrastructure and the Customer Service.
Mitigation is activated only after the attack is detected by OVH tools, and a minimum of 26 hours. Therefore until the activation of mitigation, the Service is frontally affected by the attack, which can lead to its unavailability.
As soon as the cyber attack is identified and mitigation is automatically activated, mitigation can not be disabled until the end of a 26 hours period.
Throughout the duration of the activation of mitigation, OVH can not guarantee the availability and accessibility of the Client’s applications but will try to limit the impact of this attack on Customer's Service and on OVH’s Infrastructure.
If, despite the activation of mitigation, the cyber attack is likely to jeopardize the integrity of the OVH’s or of other OVH customers, OVH will strengthen its protective measures which may cause a degradation of the Customer Service or impact its availability.
Finally, it is possible that some of the data generated by the attack can not be detected by the OVH equipment and reach the Customer Service. The effectiveness of mitigation also depends on the configuration of the Customer's Service; as such, it is up to them to verify that they have the necessary skills to ensure proper administration.
The mitigation does not exempt the Client to secure its Service, to implement security tools (firewalls ...), to regularly update its system, backup its data or to ensure the security of its computer programs (scripts, codes ...).

Dados para acesso: Mon, 23 Nov 2015 10:48:08 -0200
Foi entregue com Debian 7, tinha encomendado Debian 8.
Não cheguei a acessar. É apenas para testes, principalmente relativos a OpenStack. "Curiosamente" não veio com endereços IPv6.
23-11-2015, 13:47 #8
13:45 liberou para reinstalação. Lá vamos nós.
23-11-2015, 13:58 #9
Morreu em 58%
Daqui a z horas, quando liberar novamente, vou tentar Debian 7.
