3. Charter

SURFcert operates under a charter. This charter can be found at: R-­92-­01 Operational Framework SURF cert. Details on SURFcert operation can be found in this operational framework.

3.1 Mission statement

The primary purpose of SURFcert is to provide a mechanism for institutions within the Netherlands, connected to SURF, to deal with computer security problems and their prevention.

The goals of SURFcert are:

3.2 Constituency

The SURFcert Constituency are those sites that are connected to SURF.

3.3 Sponsorship and/or affiliation

SURF bv will fund the work of SURFcert and will fund the technical provisions needed in order to gain and maintain maximum reachability.

SURFcert is affiliated with FIRST (http://www.first.org), the Forum on Incident Response and Security Teams and maintains affiliations with various other CSIRTs around the world on an as needed basis. SURFcert is also Trusted Introducer Certified team

3.4 Authority

SURFcert operates under the auspices of, and with authority delegated by, the directors of SURF bv.

SURFcert expects to work cooperatively with system administrators, networkmanagers and users of SURF connected institutions, and, insofar as possible, to avoid authoritarian relationships. However, should circumstances warrant it, SURFcert has the authority to take the measures it deems appropriate to properly handle a computer security related incident.

SURF connected institutions who wish to appeal the actions of SURFcert should contact the SURFcert chair, Wim Biemolt.

If this recourse is not satisfactory, the matter may be referred to the SURF director through your SURF account manager.

4. Policies

4.1 Types of incident and level of support

SURFcert is authorized to address all types of computer security incidents which occur, or threaten to occur, at its constituency (see 3.2). SURFcert may act upon request of one of its constituents, or may act if a constituent is, or threatens to be, involved in a computer security incident.

The level of support given by SURFcert will vary depending on the type and severity of the incident or issue, the size of the user community affected, and the SURFcert's resources at the time, though in all cases some response will be made within one working day. Resources will be assigned according to the following priorities, listed in decreasing order:

  1. Threats to the physical or mental safety of human beings.
  2. Root or system-level attacks on any Server System, or any part of the backbone network infrastructure.
  3. Root or system-level attacks on any large public service machine, either multi-user or dedicated-purpose.
  4. Any other type of compromise which leads or may lead to unauthorised access of systems.
  5. Denial of service attacks on any of the above three items.
  6. Any of the above at other sites, originating from the constituency of SURFcert.
  7. Large-scale attacks of any kind, e.g. sniffing attacks, IRC "social engineering" attacks, password cracking attacks.
  8. Threats, harassment, and other criminal offenses involving individual user accounts.
  9. Compromise of desktop systems.
  10. Denial of service on individual user accounts, e.g. mailbombing.

Types of incidents other than those mentioned above will be prioritized according to their apparent severity and extent. These incidents will be assessed as to their relative severity at SURFcert's discretion.

SURFcert will, in principle, accept any incident report that involves an incident with one of the constituents either as a victim or as a suspect. Henceforth, reports filed by individual end users within the constituency will also be dealt with. However, SURFcert encourages the engagement of qualified security staff at the involved organisation in an early stage. Whenever feasible, SURFcert will contact the relevant Site Security Contact or the Security Entry Point of the organisation alledgedly involved, even if the end user has chosen not to do so.

While SURFcert understands that there exists great variation in the level of system administrator expertise at its constituency, and while SURFcert will endeavor to present information and assistance at a level appropriate to each person, SURFcert shall not train system administrators on the fly, and it cannot perform system maintenance on their behalf. In most cases, SURFcert will provide pointers to the information needed to implement appropriate measures.

SURF, as the organisation under whose sole jurisdiction SURFcert is operating, offers the possibility to the constituency for consultancy projects on an ad-hoc basis. In security related matters, SURFcert may at its own discretion suggest to embark on a consultancy project, which will provide for more resources where necessary in order to do a full analysis and remedial of an observed security breach.

4.2 Co-operation, interaction and disclose of information

While there are legal and ethical restrictions on the flow of information from SURFcert, all of which may also be outlined in policies at the organisations of its constituency, and all of which will be respected, SURFcert acknowledges its indebtedness to, and declares its intention to contribute to, the spirit of cooperation that created the Internet. Therefore, while appropriate measures will be taken to protect the identity of members of our constituency and members of neighbouring sites where necessary, SURFcert will otherwise share information freely when this will assist others in resolving or preventing security incidents.

In the paragraphs below, "affected parties" refers to the legitimate owners, operators, and users of the relevant computing facilities. It does not refer to unauthorized users, including otherwise authorized users making unauthorized use of a facility; such intruders may have no expectation of confidentiality from SURFcert. They may or may not have legal rights to confidentiality; such rights will of course be respected where they exist. SURFcert may release information to any third party or to governing authorities whenever there is a legal obligation to do so. However, SURFcert may in some cases delay this action until such a circumstance has been established irrevocably, e.g. by court order. SURFcert will in such cases always notify the affected persons or organisations.

Information being considered for release will be classified as follows:

Potential recipients of information from SURFcert will be classified as follows:

4.3 Communication and authentication

In view of the types of information that SURFcert will likely be dealing with, telephones will be considered sufficiently secure to be used even 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 to be similar to e-mail for these purposes: sensitive data should be encrypted before transmission.

Where it is necessary to establish trust, for example before relying on information given to SURFcert, or before disclosing confidential information, the identity and bona fide of the other party will be ascertained to a reasonable degree of trust. Within the constituency, and with known neighbour 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).

SURFcert keys can be found on https://keys.openpgp.org/search?q=cert@surfcert.nl.
