3. Charter

3.1 Mission Statement

CYNET-CSIRT provides incident response and security services to all Academic Institutions, Research Institutes and educational networks that are members of the Cyprus Research & Academic Network (CYNET).
It also provides early warning, alerts, announcements and dissemination of information to its constituency and relevant parties regarding risks and incidents. This is accomplished by acting as an intermediary between affected parties and offering, when required, technical advice leading to the resolution of the incident. The affected parties may be internal or external entities to CYNET. CYNET-CSIRT aims to educate its members about the effects of cyber threats and cyber-crime, and train them to provide early warnings, alerts, announcements and efficient use of the respective tools.

3.2 Establishment

The CYNET-CSIRT was established in 2017 according to the Commissioner of Electronic Communications and Postal Regulation decision Action No. 358/2010.

Responsibilities of the CYNET-CSIRT:

  1. The response to the information security incidents in cooperation with the universities and research institutes of Cyprus, as well as similar organisations;
  2. Awareness raising in the field of information security;
  3. Cooperation with European CSIRT teams;

3.3 Constituency

CYNET-CSIRT’s constituency is the CYNET community, comprising Academic Private Institutes and similar organisations, Research Institutes and similar organisations and Public and Private Schools.

CYNET-CSIRT may provide CSIRT support to other public or private organizations upon signing a binding legal agreement.

3.4 Affiliation

CYNET-CSIRT is the Incident Response Team of the Cyprus Academic and Research Network (CYNET). CYNET-CSIRT cooperates with other European CSIRT teams, inter alia, the National CSIRT-CY team and the Digital Security Authority of Cyprus.

3.5 Authority

CYNET-CSIRT coordinates incidents on behalf of its constituency. CYNET-CSIRT is authorized to take operational actions regarding vulnerabilities and mitigation of incidents. Such actions may include but are not limited to blocking access to the CYNET network.

 

4. Policies

4.1 Types of Incidents and Level of Support

CYNET-CSIRT is authorized to address all types of computer security incidents which occur, or threaten to occur, at CYNET and its members (as defined in 3.2).

CYNET-CSIRT is committed to informing its constituency and to issue alerts and warnings. Furthermore, it analyses the logs from incidents, vulnerabilities and artefacts and performs incident response. The team actively maintains and tests a list of updated security software tools that are used to assist in various activities such as system audits, vulnerability analysis, antivirus and malware handling tasks. These tools are available to all interested parties and to the best of the team’s knowledge do not contain software that may exploit known or unknown system vulnerabilities. In addition, it collects various documents related to security issues, such as technical “how to” guides and documentation on system security related techniques, such as system installations, evidence handling, etc.

CYNET-CSIRT will respond to request for assistance by other CSIRTs external to CYNET. CYNET-CSIRT will usually respond within the same work day to request for incident response.

The level of support offered by the CYNET-CSIRT depends on the type of constituent, the severity and the impact of the incident.

4.2 Co-operation, Interaction and Disclosure of Information

The CYNET-CSIRT highly regards the importance of operational cooperation and information sharing between Computer Security Incident Response Teams, and also with other organizations which may contribute towards or make use of their services. All sensitive data and information (personal data, system/service configuration, vulnerabilities with their locations) are transmitted encrypted. The CYNET-CSIRT operates in accordance with the GDPR and supports the Traffic Light Protocol (TLP).

CYNET-CSIRT aims to (and is working towards) participate in the TF-CSIRT (Task Force – Computer Security Incident Response Team) program of TERENA and attend its meetings. It also aims to participate in the Trusted Introducer that has been established to facilitate the communication between European CSIRTs.

CYNET-CSIRT wishes to acknowledge 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, CYNET-CSIRT will otherwise share information freely in order to assist with the resolution and/or prevention of security incidents. CYNET-CSIRT may release information to any third party or to governing authorities whenever there is a legal obligation to do so.

Vulnerability information will be released freely, though every effort will be made to inform and work with the relevant vendor before the general public is informed. Statistical information will be released at the discretion of CYNET-CSIRT. Other sites and CSIRT’s, when they are partners in the investigation of a computer security incident, can be trusted with confidential information. This will happen only if the other site’s credentials can be verified and the information transmitted will be limited to that which is likely to be helpful in resolving the incident. Law enforcement officers will receive legally required cooperation from CYNET-CSIRT.

4.3 Communication and Authentication

For normal communication not containing sensitive information CYNET-CSIRT might use conventional methods like unencrypted e-mail or fax.

For Secure communication, the preferred method of communication is by digitally signed email by using either PGP (to be established) or other well-known cryptographical means.

Note digital signatures with self-signed certificates will not be considered secure. Telephone communication 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 non-sensitive data. Where it is necessary to establish trust, for example before relying on information given to CYNET-CSIRT, or before disclosing confidential information, the identity and trust level of the other party will be ascertained to a reasonable degree. Within the constituency, and referrals from known trusted people will suffice to identify someone. Otherwise, appropriate methods will be used, such as a search of FIRST or TI members, the use of WHOIS and other Internet registration information, 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. Note that self-signed digital certificates are not considered adequate for establishing the identity of the communicating party.
