SSH Key And IAM (Identity and Access Management) — An Insight Into Data Security.
Secure Shell Keys (SSH Key)
Data security is one of the most important components of a progressive IT world. Security, accuracy, and integrity of data is a must for any organization. In today’s day and age, data is equally important as finances, employees, and whatnot. To ensure data security, different mechanisms are used by different organizations based on their scale, level of operation, and work area. SSH i.e Secure Shell keys are one of the most widely used methods to ensure data security.
An SSH key is an access credential in the SSH protocol. These keys are based on the principle of Public-key cryptography. A pair of encryption keys are generated which are mathematically linked to each other: a private key and a public key. The public key is used to encrypt a message whereas the private key is used to decrypt it. This provides a very nice property that allows anyone having access to the public key to encrypt a message that can only be decrypted by someone with access to the private key.
Identity and access management (IAM) definition
Identity and access management (IAM) in enterprise IT is about defining and managing the roles and access privileges of individual network users and the circumstances in which users are granted (or denied) those privileges. Those users might be customers (customer identity management) or employees (employee identity management. The core objective of IAM systems is one digital identity per individual. Once that digital identity has been established, it must be maintained, modified, and monitored throughout each user’s “access life cycle.”
On a fundamental level, IAM encompasses the following components:
✔How individuals are identified in a system (understand the difference between identity management and authentication)
✔How roles are identified in a system and how they are assigned to individuals
✔Adding, removing, and updating individuals and their roles in a system
✔Assigning levels of access to individuals or groups of individuals
✔Protecting the sensitive data within the system and securing the system itself.
Why is Identity and access management important?
Businesses leaders and IT departments are under increased regulatory and organizational pressure to protect access to corporate resources. As a result, they can no longer rely on manual and error-prone processes to assign and track user privileges. IAM automates these tasks and enables granular access control and auditing of all corporate assets on-premises and in the cloud.
Benefits of IAM
IAM brings an organization the following IAM benefits:
- Access privileges are granted according to policy, and all individuals and services are properly authenticated, authorized and audited.
- Companies that properly manage identities have greater control of user access, which reduces the risk of internal and external data breaches.
- Automating IAM systems allows businesses to operate more efficiently by decreasing the effort, time, and money that would be required to manually manage access to their networks.
To protect data integrity, security, and consistency, it is imperative to have robust security protocols in place. This is where SSH Keys and IAM comes in. Effective and efficient use of these policies can go a long way in DATA SECURITY and hence putting the organization towards the path of success.
