There are two actors on every network human and machines. Just human identities are protected with usernames and passwords, machine identities are protected with keys and certificates.
Machine identity on a network
Machine use hides connections to found trust in all kind of digital transactions. Machine identities use digital certificates to validate the authority of both communicating machines.
Varying different use of machine identities across organizations, the challenges related to managing them are consistently the same:
(1) Visibility: When we talk about companies of size the response is that they don’t know how many keys and certificate they have, what policies they comply with, or when they expire.
(2) Protection: Machine identities are based on trust model. Private keys must be stored and protected against arrangement.
(3) Automation: Manual processes are time consuming; they are also open to error and ineffective at scale.
Adopting the Zero trust models
As per the regular security models, all devices inside the company’s network are safe and can be unspoken trusted. Verification of digital identities on your network is significant to a Zero Trust planning.

What are Machine Identities
Jump on a device of some sort, and log on with a username and password. Machines can’t enter a username and password. Instead, they use a set of credentials better suited for highly automated and connected environments – these include:
SSL/TLS Server Certificates establish trust in your public-facing websites and applications, which are deployed on things like web servers, app servers, and load balancers. Without proper visibility, these certificates expire unexpectedly and trigger costly application outage.
SSL/TLS Client Certificates are used to authenticate the identity of users, web services, or machines to one another. These have become much more prevalent with the explosion of DevOps, mobile and IoT devices, cloud and microservices. They typically outnumber server-side SSL/TLS certificates by a factor of 1,000 or more, but are often a ‘blind spot’ for organizations, increasing the likelihood of an outage.
SSH Keys provide users, typically system admins, with secure privileged access to critical systems. They also secure various automated processes and machine-to-machine transactions in enterprise networks. Unlike SSL certificates, SSH keys don’t expire, meaning thousands often sit forgotten across the network, leaving the door open for SSH-based attacks.
Why Machine Identity Management is Critical
Despite varying different use cases for machine identities across organizations, the challenges related to managing them are consistently the same:
·
Visibility- When we talk to companies – regardless of size or industry – the overwhelming response is that they don’t know how many keys and certificates they have, who they belong to, what policies they comply with, or when they expire.
·
Governance- The next problem is lack of ownership and control. This is particularly true for SSL/TLS certificates and SSH keys used by various teams across the organization, often without consistent policy or oversight over how they are issued, who has access, when to rotate or renew, etc.
·
Protection- Machine identities are based on a model of trust. X.509 certificates must be issued from a trusted certificate authority (CA). Private keys must be stored and protected against compromise. If these protections aren’t in place, machine identities can’t be trusted.
·
Automation- Manual processes aren’t just time-consuming; they’re also open to error and ineffective at scale. For example, handling the lifecycle of certificates – from servicing requests to issuance and installation, and eventually revocation or renewal – is often entirely manual, creating hours of work for admin and users alike.
