What is PKI?

Public Key Infrastructure

Questions on your mind?

We often read about PKI over the net or on the cybersecurity columns even though we know its full form i.e. Public Key Infrastructure.

What is the relation PKI has with CA certificates and how all these are interlinked what key are we talking about, why only keys, not locks??

To answer all these questions we have written this blog in simple terms we will be able to make you understand about PKI.

Answers !!

PKI is the framework of encryption and cybersecurity that protects communication between server (your website) and the client (the users).

There are two keys by which PKI is working from:

  • Public Key
  • Private Key

The public key is available to any user that connects with the website.

The private key is a unique key generated when a connection is made, and it is kept secret.

How it Works?

When communicating, the client uses the public key to encrypt and decrypt, and the server uses the private key. This protects the user’s information from theft or tampering.

There are several elements in PKI one of them is a  Certificate Authority (CA) which is used to authenticate the digital identities of the users, which can range from individuals to computer systems to servers.  

The second component is Registration Authority (RA), which is authorized by the Certificate Authority to provide digital certificates to users on a case-by-case basis.

What is Patch Compliance?

To explain you about a patch compliance lets imagine that when you are working out in the morning while lifting those 25kg dumbles you somehow got hurt on your knees or legs that too a minor cut what you do?

You apply an antiseptic or a Band-Aid so that the cut doesn’t go deeper and get spoiled by airborne viruses. As in the Band-Aid is removed you are back on your daily life routine.

How Band-aid is connected to Patch Management?

So now just imagine if your system or a machine which on an everyday usage keeps on getting cuts and before it goes deeper it should be applied with a Band-Aid that is it should be kept updated with all the latest patches to remove vulnerabilities.

In a technical language a patch management is the process of managing a network of computers by regularly performing patch deployment to keep computers up to date.  This helps to reduce the system-related failures so you can improve productivity and save on the costs associated with poor patch management.

The benefits which one can have after updating patches:

  • Security:  The network security is strengthen to avoid any data breach.
  • Productivity:  The patch update increases the productivity of the system which thereafter increases the profits of the businesses.
  • Compliance:  Patch management ensures that you stay within compliance of the security standards.

What is Information Security?


Information Security is also known as InfoSec, it is all about securing information from unauthorised access which can be done through tools, processes deployed to protect sensitive business information from modification, disruption, destruction and inspection.

These information can be anything from the data stored in your personal laptops , mobiles or anything stored on your social media platform.

There are three pillars of Information Security which are commonly known as :

C – Confidentiality

The information which is not disclosed to unauthorised individuals, entities and process. For example, if we say I have a password for my Facebook account but someone has seen me entering the password through shoulder-surfing when I was trying to login to my account. In such a scenario my password has been compromised and confidentiality has been breached.

I – Integrity

It means maintaining accuracy and completeness of data. This means data cannot be edited in an unauthorised way. 

For example if a person has been diagnosed with an untreated disease and dies due to the same then in this scenario his confidential data such as account details should be updated and closed by the bank authorities to reflect status as ACCOUNT CLOSED so that data is complete and accurate and in addition to this only authorised person should be allowed to edit the account holders details.

A – Availability.

It means information must be available when needed. For example : if an employee who joins a new organisation and the new company wants to do a background check for this employee so in such a scenario the authorities need to share the information related to the employee when needed to the authorised source.

Difference between InfoSec and CyberSecurity?

Information security and cybersecurity are often confused. InfoSec is a crucial part of cybersecurity, but it refers exclusively to the processes designed for data security. Cybersecurity is a more general term that includes InfoSec.
