Conclusions 16 03 Annual Report Trust Services Security Incidents 2017 Executive Summary Electronic trust services are a range of services around digital signatures, digital certificates, electronic seals, timestamps, etc. which are used in electronic transactions, to make them secure. eIDAS1, an EU regulation, is the EU wide legal framework ensuring interoperability and security of these electronic trust services across the EU. One of the goals of eIDAS is to ensure that electronic transactions can have the same legal standing as traditional paper based transactions. eIDAS is important for the European digital market because it allows businesses and citizens to work and use services across the EU. The eIDAS regulation was adopted in July 2014 and came into force in 2016. Article 19 of the eIDAS regulation sets security requirements for trust service providers. National supervisory bodies have to supervise the trust service providers in their country to ensure that they fulfil these requirements. Cooperation and agreement on how to do this in practice is important not only to create a level playing field for providers operating out of different EU countries, but also to protect transactions based on these services. If there is, for instance, a cyber-attack on a trust service provider in one Member State, then this could have an impact on organizations in other parts of the EU who rely on the provider’s trust services. An important part of Article 19 is the mandatory security breach notification requirements: Trust service providers must notify the national supervisory body about security breaches, if there is a significant impact on the trust service(s) they provide. Article 19 requires national supervisory bodies to inform each other and ENISA if there is cross-border impact. Annually, the national supervisory bodies send annual summary reports about the notified breaches to ENISA and the European Commission. This document, the Annual Report Trust Services Security Incidents 2017, marks the second round of security incident reporting for the EU’s trust services sector For 2017, the national supervisory bodies reported 13 security breaches with a significant impact on trust services. We can draw the following conclusions: Notification increase: The number of notified security breaches increased significantly, in comparison to the previous year. This is not a sign of decreasing security, but rather shows that the implementation of the breach reporting requirements is maturing. Trust service providers are more aware of their breach reporting obligations and are becoming more familiar with the procedure. This leads to more notifications to the supervisory bodies. E-signatures and e-seals most affected: Almost half of the notified breaches, 43%, involve certificates for electronic signatures and electronic seals. Most common causes are system failures, third party failures: System failures, third party failures are both responsible for 36% of the breaches. Human errors are more rare (21%). Only 7% of the breaches are caused by malicious actions. Many security breaches had cross-border impact: Almost half of the notified breaches, 46%, had an impact across borders. This shows that indeed the EU trust services sector is cross-border. Many providers (and their suppliers) are offering services across the EU. Half those were severe, i.e. 50% the cross-border incidents had the highest severity rating (5- disastrous). A third of the breaches were due to ROCA: A number of notified breaches had the same underlying cause (the ROCA case). The general conclusion is that, particularly for security supervision of trust services, cross-border collaboration and information exchange between EU Member States are very important and are starting to produce concrete results 1 Regulation (EU) No 910/2014 of the European Parliament and of the Council of 23 July 2014 on electronic identification and trust services for electronic transactions in the internal market and repealing Directive 1999/93/EC, can be consulted at https://eur- lex.europa.eu/eli/reg/2014/910/oj 04 Annual Report Trust Services Security Incidents 2017 that are of value to the community. The eIDAS regulation, and Article 19 in particular, provides the legal basis for collaboration and information exchange between the supervisory bodies. Detailed discussions about security issues and supervision of the sector take place inside the ENISA Article 19 expert group, which is an informal group of experts from national supervisory bodies focusing on the practical implementation of Article 19. 05 Annual Report Trust Services Security Incidents 2017 1. Introduction According to Article 19 of the eIDAS Regulation, Electronic Trust Service Providers in the EU have to notify the national supervisory bodies in their country about security incidents. Annually the supervisory bodies send summaries of these incident reports to ENISA. Subsequently ENISA publishes an aggregated overview of these security incidents. This document gives an aggregate overview of the reported security incidents. This annual report marks the second round of security incident reporting in the EU’s trust services sector, covering the security incidents of 2017. This document only contains aggregated and anonymized information about incidents and does not include details about individual countries or individual trust service providers. Detailed discussions about the reported security incidents take place in the ENISA Article 19 expert

  • Digital Identity Management
    Digital Identity Management An AIT White Paper These days people wish to move both freely and safely; to cross borders swiftly with secure access controls without hindrances; to make transactions payments or access governmental services through quick and convenient proof of identity. We are addressing here the major issues the security discipline and processes. All the above come with new regulations initiated by the European Commission as the new GDPR (General Data Protection Rules). Introduction Identity Management (IDM) is the organisational key process for identifying, authenticating and authorising individuals or groups of people to access applications, systems or networks by associating user’s rights and restrictions with established identities. The managed identities can also refer to software processes that need access to organisational systems. Authentication It is widely agreed that the first step of action for verifying the identity of a user or process is through the control access and proof of identity (authentication). To establish this process three main categories (factors) are used: Figure 1. Three different authentication factors, source: AIT Something you know Knowledge factors are the most commonly used form of authentication. The user is required to prove knowledge of a secret to authenticate him. A “password” is a secret word or string of characters that is used for user authentication. Variations include both longer ones formed from multiple words (a passphrase) and the shorter, purely numeric, Personal Identification Number (PIN) commonly used for ATM access. Traditionally, passwords/PINs are expected to be memorised. Something you have Possession factors ("something only the user has") have been used for authentication for centuries, in the form of a key to a lock.

  • As Devastating As KRACK: New Vulnerability Undermines RSA Encryption Keys a New Security Flaw Has Placed the Security of RSA Encryption in Jeopardy
    As devastating as KRACK: New vulnerability undermines RSA encryption keys A new security flaw has placed the security of RSA encryption in jeopardy. By Charlie Osborne for Zero Day | October 17, 2017 -- 08:57 GMT (09:57 BST) | Topic: Security http://www.zdnet.com/article/as-devastating-as-krack-new-vulnerability-undermines- rsa-encryption-keys/ 3 88 344 (Image: File Photo) Flawed chipsets used by PCs to generate RSA encryption keys have a vulnerability that has weakened the security of stored passwords, encrypted disks, documents, and more. MORE SECURITY NEWS Android security: Google cracks down on apps that want to use accessibility services Resilience to phishing attacks is failing to improve Google: Our hunt for hackers reveals phishing is far deadlier than data breaches Equifax spends $87.5 million on data breach, more expenses on deck This week, researchers from the Centre for Research on Cryptography and Security at Masaryk University, Czech Republic; Enigma Bridge Ltd, Cambridge, UK; and Ca' Foscari University of Venice, Italy, revealed the flaw in cryptographic smartcards, security tokens, chipsets and secure hardware manufactured by German semiconductor firm Infineon Technologies. The ROCA vulnerability, CVE-2017-15361, relates to the Trusted Platform Module (TPM) used to cryptographically sign and protect computer systems and services. The bug was discovered within the implementation of RSA keypair generation in a cryptographic library used by Infineon TPM products, allowing what is called a "practical factorization attack." This attack type permits a threat actor to use a target's public key to generate a private key with some time and power. The attack is possible for common key lengths, including 1024 and 2048 bits.
