Introduction Yearly 1.5 million cyber-attacks translate to 4000 attacks every day, 170 per hour and almost three every minute (Deloitte, 2016), associated with an average cost of $3.86 million U.S. dollars for each successful attack resulting in a breach, where the average time to identify a breach is 196 days (IBM, 2018). These numbers demonstrate the hardship in securing cyberspace. High pace developments in technology constantly throw up new challenges (Linkov, 2013). Organisations can therefore no longer deny the need for cyber security and are urged to implement security measures. However, the rising number and complexity of cyber- attacks makes preventing cyber incidents a difficult – if not impossible – endeavour. Rather than aiming to prevent cyber incidents from happening, the focus has shifted towards cyber resilience, which helps to bounce back, minimise the impact and ensure process continuity (Conklin, 2017). Furthermore, cyber resilience is not a merely technical issue, but encompasses organisational, business, financial and legal aspects (Van der Meulen, 2015). Technology is the accessory, and for organisations to improve cyber resilience there is need for a comprehensive approach that considers the multiple dimensions and aspects of the issue. Current cyber resilience frameworks offer clear overviews of five main steps in the process towards cyber resilience, but often lack the wider organisational context and a connection to practice (Bagheri, 2017) (Knapp, 2009). This thesis presents a comprehensive overview of the issues that are currently left out, underexposed, or sprawled across the literature on cyber resilience. It adopts a helicopter view to the literature and combines strategic, organisational and legal perspectives to increase the understanding of organisations and academics on the non-technical aspects of cyber resilience.

These forces have shaped their worldviews, values, and behaviors. Digital natives’ ability to connect, convene, and create disruption via their keyboards and smartphones has had global impact. From #MeToo to Black Lives Matter, from convening marches on climate change to the Arab Spring, from demanding eco-friendly products to challenging stakeholder capitalism, these generations are compelling real change in society and business. The lockdowns resulting from the COVID-19 pandemic curtailed millennials’ and Gen Zs’ activities but not their drive or their desire to be heard. In fact, the 2021 Deloitte Global Millennial Survey suggests that the pandemic, extreme climate events, and a charged sociopolitical atmosphere may have reinforced people’s passions and given them oxygen. 01 Urging accountability Last year’s report1 reflected the results of two Of course, that’s a generality—no group of people is surveys—one taken just before the pandemic and a homogeneous.

  • Improving PKI Solution Analysis in Case of CA Compromisation
    Master Game and Media Technology Improving PKI Solution analysis in case of CA compromisation Samira Zaker Soltani January 2013 Utrecht University Faculty Computer Science Deloitte Nederland Deloitte Risk Services Supervisors: Gerard Tel - Univeristy Utrecht Henk Marsman - Deloitte Nederland To my mother, for she is the reason. Abstract Creating a secure connection on the Internet is made possible through the usage of certificates, binding an entity to its public key. These certificates can be issued by any of the Certificate Authorities (CA), where each CA has the same privileges. During the last year, we have seen many CA compromises, resulting into the issuance of fraudulent certificates. Fraudulent certificates can be used, in combination with the man-in-the-middle attack, to eavesdrop the communications of Internet users. This research focuses on solutions that can remove or limit the impact of a CA com- promisation and provides a description and analysis of each solution. The solutions have been chosen through interviews and literature. Among the discussed solutions are Public Key Pinning, Sovereign Keys, Certificate Transparency, Perspectives & Convergence, DANE, and MCS. In order to identify each solution’s advantages and disadvantages, we have created a metric of aspects. The aspects have been categorized into security, usability, and costs. The focus of this research has been on security, since that is the aspect in Public Key Infrastructure we are trying to solve. The results indicate that Certificate Transparency and DANE are the most promis- ing solutions for limiting the risks of a compromised CA. Further research will be needed to complete each solution, since both solutions are not yet ready for deploy- ment.

The survey information security programmes (cyber security) in Central Asia, as follows: covers various industries and addresses how organisations view, formulate, implement and maintain their information security programmes. 1.
