A little bit about the ISO 27001 standard

By Sin categoría No Comments

Si hablamos de normativas fundamentales en nuestra labor digital, la ISO 27001 es el eje central. Su objetivo es proteger la confidencialidad, integridad y disponibilidad de la información en una empresa. Este tipo de actividad se realiza mediante la investigación de cuáles son los potenciales problemas que podrían afectar a la información, es decir, una evaluación de riesgos. 

Por otra parte define en fondo y forma que elementos son necesarios para evitar que estos problemas se produzcan.

Esta norma puede ser implementada en cualquier tipo de organización ya que proporciona una metodología de cara a implementar una gestión de la seguridad de la información en una organización. Una vez solventado ese camino, permite que una empresa sea certificada por una entidad de certificación como la nuestra, confirmando así su seguridad en lo que a información se refiere.

Por tanto, podemos definir que la norma ISO 27001 basa su funcionamiento principal en  gestionar riesgos, investigar su procedencia y ser tratados de forma adecuada.

As streets, businesses, and public buildings emptied, other places took center stage. Electronic notifications were already doing so, but they are another of the protagonists of this period of State of Alarm due to the COVID-19 pandemic.

An electronic system of notifications allows any type of natural or legal person to receive the different notices and documents that the Public Administrations have issued in digital format.

The Tax Agency, the Directorate General of Traffic, and the Social Security are the main issuing bodies of this type of notification that allow public entities to make significant savings in terms of messaging and users to save travel time as they no longer have to be present when the notification is delivered.

The private sector has also developed reliable notification systems, which can now be adapted to the requirements of EU Regulation 910/2014 (EIDAS) and can thus be converted into certified delivery systems. This is provided for in Articles 43 and 44 of the EIDAS Regulation:

Electronic or digital signature and seal

By #eIdAS, Advanced Signature, Electronic Certificates, electronic delivery, EN 319 412, Firma cualificada, Qualified Seal, Qualified Signature, Secure Signature Creation Devices, Sello cualificado No Comments

Electronic signatures and electronic seals are cryptographic operations that associate a document (the signed or sealed document) with the identity of a natural or legal person.

Both operations are technically similar. Their main difference is that the electronic signature is associated with a natural person and the electronic seal is associated with a legal person.

When the electronic signature is carried out with an electronic certificate and its associated private key, there can be different variants:

  • Advanced Signature. There are no special requirements regarding the certificate.
  • Semi-qualified Signature. The certificate must be qualified. That is to say, it must contain the OID “id-etsi-qcs-QcCompliance” qcs-QcCompliance(1)
  • Qualified Signature. The certificate must be qualified and based on a qualified device. I.e. it must contain the OID “id-etsi-qcs-QcCompliance” qcs-QcCompliance(1) and the OID “id-etsi-qcs-QcSSCD” qcs-QcCompliance(4).

Similarly, when the electronic seal is performed with an electronic certificate and its associated private key, the same variants may occur:

  • Advanced Seal. There are no special requirements regarding the certificate.
  • Semi-qualified Seal. The certificate must be qualified. I.e. it must contain the OID “id-etsi-qcs-QcCompliance” qcs-QcCompliance(1)
  • Qualified Seal. The certificate must be qualified and based on a qualified device. i.e. it must contain the OID “id-etsi-qcs-QcCompliance” qcs-QcCompliance(1) and the OID “id-etsi-qcs-QcSSCD” qcs-QcCompliance(4)
