Give me your opinion on Blockchain technology, and how do you think it will revolutionize cyber security?
Since Blockchain was introduced to the market, security technologists have been busy keeping Blockchain transactions secure through distributed networks so people can use bitcoin or crypto-currency as a payment gateway. Hiring managers, especially in the finance/banking industries, are well aware of this technology, so when they ask this question, they are looking for your opinion on how it applies to cyber security. They expect you to be well versed in this area and to be able to respond with a strong, fact-based opinion that examples and presidents can support.
"Anytime I see the introduction of a new technology or payment gateway, I take it upon myself to research that technology to see where it is relevant in the world of Cyber Security. When Blockchain came out, I did extensive research on where it might have vulnerabilities, and be susceptible to attacks. According to my research, Blockchain has been around for about a decade and was initially introduced to store and/or send crypto-currency like Bitcoin. Blockchains are distributed networks with millions of users all over the world. Since Blockchain uses cryptology, it's easier for businesses to authenticate devices and users without the need for a password. This definitely eliminates manual intervention in the process of authentication, thereby avoiding potential attacks."
"The way I view Blockchain revolutionizing Cyber Security is through decentralized storage, record keeping, and peer-to-peer sharing. Furthermore, Blockchain users will be able to store all their data on their network or computer if they choose to do so. Basically, a blockchain is a decentralized, digitized, public ledger of all cryptocurrency transactions known as Distributed Ledger Technology. One of the big reasons why I think blockchain is going to be an integral part of Cyber Security is (Distributed Denial of Service. In a nutshell, Blockchain transactions can be denied easily if the send-receive participants are impeded from sending transactions. Blockchains provide a non 'hackable' entrance point, thereby, provide more security when compared with database-driven transactional structures."
If you have experience working in an environment that uses Blockchain, showcase that experience in a way that makes you stand out from the crowd. For example, use a scenario (without giving away sensitive company information) where you used it and how you could protect web servers and ID systems so the transactions were safe and secure. If you have limited knowledge of Blockchain, show your eagerness to learn the technology and how your skills would apply in those situations.
