Overview of this book

Organizations have always been a target of cybercrime. Hands-On Cybersecurity for Finance teaches you how to successfully defend your system against common cyber threats, making sure your financial services are a step ahead in terms of security. The book begins by providing an overall description of cybersecurity, guiding you through some of the most important services and technologies currently at risk from cyber threats. Once you have familiarized yourself with the topic, you will explore specific technologies and threats based on case studies and real-life scenarios. As you progress through the chapters, you will discover vulnerabilities and bugs (including the human risk factor), gaining an expert-level view of the most recent threats. You'll then explore information on how you can achieve data and infrastructure protection. In the concluding chapters, you will cover recent and significant updates to procedures and configurations, accompanied by important details related to cybersecurity research and development in IT-based financial services.

Encryption today

The invention of computers led to great leaps in encryption. The first state-of-the-art encryption method was the Data Encryption Standard (DES), invented in 1979. The encryption algorithm was celebrated as the unbreakable 56-bit encryption and not even the most capable supercomputers were able to break it through brute force. It was estimated by its inventors that the computers would take at least 20 years in order to break a ciphertext made using DES. However, advances in computing and particularly the processing power led to DES being broken twice in a short period of time. In 1998 and 1999, DES was broken in 56 and 22 hours respectively, instead of the estimated 20 years. From then, there was a need to replace DES, and AES was then created after the public was invited to participate in a competition to build a secure encryption algorithm. 15 proposals were...
