When it comes to PKI (Public Key Infrastructure), there are a lot of different aspects to consider. In this blog post, we’ll be discussing some of the most commonly asked questions about PKI in interviews. This will include questions about what PKI is, how it works, and why it’s used. We’ll also touch on some of the challenges that can come with PKI and how to overcome them.
What is Public Key Infrastructure (PKI)?| Cybersecurity Interview Questions and Answers| Security
Ans: This we can understand with help of the example. Assume Tom wants to send electronic documents to Eric digitally. Tom and Eric have acquired digital signatures. Public and private keys are two characteristics of the subscriber that are included in the digital signature. First, both have shared public key with each other. Now, Tom uses his private key to encrypt the message and send it to Eric. After receiving, Eric will decrypt the message using Tom’s shared public key to ensure the message’s integrity. By using DSC, Tom can do this while exchanging messages in a secure manner.
Answer: A digital signature certificate (DSC) is a digital version of a signature. It serves as identification and authentication documentation. Accessing information or services on the internet is another use for it. DSC is a technique for verifying the legitimacy and integrity of electronic messages or data, to put it another way.
These days, digital signature certificates protect the authenticity and integrity of data over an unreliable network. Here, we’ll go over interview inquiries and responses relating to digital signature ideas.

Jeff Stapleton, coauthor of Security Without Obscurity: A Guide to PKI Operations, said the following in a recent Q&A:
It goes without saying that a properly developed and implemented PKI will aid your company in managing and protecting data both now and in the future. However, there are many misperceptions and assumptions about PKI. Deploying PKI in an environment is not a quick process. According to a different study, Global Encryption Trends Study by Thales and Ponemon Institute, 57% of respondents say that managing keys can be a very difficult activity. 2.

Why do you need CMS if a CA handles the fundamentals of certificate management?
PKI has been one of the best technologies for user and device authentication for many years. However, many businesses observe that the PKI evolution does not keep pace with the expanding demands of users. Many issues arise as a result of legacy systems’ inability to satisfy modern customer demands. We asked PKI expert Nikolay Lazitskiy to respond to the most difficult and perplexing queries from customers around the world.

PKI is not only alive but also actively evolving. Any size business or company can benefit from using it properly. The certificate management system can make your PKI experience as efficient as possible. With the right CMS in place, you can automate the process, lessen the workload for the IT department, cut costs for the business, and raise security.
FAQ
What protocol is used for PKI?
Secure Sockets Layer (SSL) protocols are one of the PKI framework’s most widely used applications. SSL and Transport Layer Security (TLS), its successor, aid in creating the encrypted and authenticated links between various networked computers used in PKI.
What is PKI and how does it work?
To secure and authenticate digital communications, a framework of encryption is made up of a variety of technologies and procedures. PKI uses digital certificates and cryptographic public keys to authenticate the device or user sending the digital communication.
What are the two components of PKI?
A private PKI’s certificate authority (CA) serves as a trusted component and issues certificates for entities. A certificate is a digital document that is signed by a CA and used in a PKI to demonstrate who is the owner of a public key.
How many types of PKI are there?
There are three common types of PKI certificates: SSL/TLS certificates. code signing certificates. client certificates.
