4Policies

4.1Types of Incidents and Level of Support

Grupo Banco Sabadell CERT is authorized to address all types of computer security incidents that occur at its constituency.

All incident reports received by Grupo Banco Sabadell CERT are analyzed, classified and prioritized according to an internal incident classification policy so that an efficient and appropriate level of service is provided.

Resources will be assigned according to the following priorities:

• Threats to the physical safety of human beings.
• Root or system-level attacks on any Management Information System or any part of the backbone network infrastructure.
• Root or system-level attacks on any large public service machine, either multi-user or dedicated-purpose.
• Compromise of restricted confidential service accounts or software installations, in particular those used for MIS applications containing confidential data, or those used for system administration.
• Denial of service attacks on any of the above three items.Any of the above at other sites, originating from the constituency of Grupo Banco Sabadell CERT.
• Large-scale attacks of any kind.
• Threats, harassment, and other criminal offenses involving individual user accounts.
• Compromise of individual user accounts on multi-user systems.
• Compromise of desktop systems.
• Forgery and misrepresentation, and other security-related violations of local rules and regulations.
• Denial of service on individual user accounts.

Types of incidents other than those mentioned above will be prioritized according to their apparent severity and extent.

Note that no direct support will be given to end users; they are expected to contact their system administrator, network administrator, or department head for assistance. In most cases, Grupo Banco Sabadell CERT will provide pointers to the information needed to implement appropriate measures.

Grupo Banco Sabadell CERT is committed to keeping the constituency informed of potential vulnerabilities, and where possible, will inform this community of such vulnerabilities before they are actively exploited.

4.2Co-operation, Interaction and Disclosure of Information

Grupo Banco Sabadell CERT will cooperate with other organizations in the field of computer security. This cooperation also includes and often requires the exchange of information regarding security incidents and vulnerabilities. Nevertheless Grupo Banco Sabadell CERT will protect the privacy of its constituency and therefore (under normal circumstances) pass on information in an anonymized way only.

Grupo Banco Sabadell CERT will only provide information to other parties with the sole purpose of facilitating the tasks of containment, eradication and recovery of incidents under the general principle of providing the minimum information possible.

Grupo Banco Sabadell CERT operates under the restrictions imposed by the law of Spanish Data

Protection Authority. Therefore it is also possible that Grupo Banco Sabadell CERT may be forced to disclose information due to a Court’s order.

4.3Communication and Authentication

In view of the types of information that the Grupo Banco Sabadell CERT will likely be dealing with, telephones will be considered sufficiently secure to be used even if unencrypted. Unencrypted e-mail will not be considered particularly secure, but will be sufficient for the transmission of low-sensitivity data. If it is necessary to send highly sensitive data by e-mail, PGP will be used. Network file transfers will be considered similar to e-mail for these purposes: sensitive data should be encrypted for transmission.

Where it is necessary to establish trust, for example before relying on information given to the Grupo Banco Sabadell CERT, or before disclosing confidential information, the identity of the other party will be ascertained to a reasonable degree of trust. Within Community, and with known neighbor sites, referrals from known trusted people will suffice to identify someone. Otherwise, appropriate methods will be used, such as a search of FIRST members, the use of WHOIS and other Internet registration information, etc., along with telephone call-back or e-mail mail-back to ensure that the party is not an impostor. Incoming e-mail whose data must be trusted will be checked with the originator personally, or by means of digital signatures (PGP in particular is supported).
