What is a CSR?

A Certificate Signing Request (CSR) is essentially a stepping stone in acquiring a digital certificate, which plays a crucial role in enabling secure communication over the internet. This process starts by generating a private key and a CSR on your server. The CSR contains information like your organization's name, domain name, locality, and country. It also carries a public key that will be included in the certificate. Once the CSR is created, it's sent to a Certificate Authority (CA) to apply for a digital certificate. The CA validates the information, signs the certificate with its private key, and issues it back. This digital certificate can now be installed on your server to establish a secure sockets layer (SSL) or transport layer security (TLS) communication.

What is a PEM File?

When delving into the realms of digital security, you might come across various file formats pivotal to encryption and authentication processes. One such format is the PEM file. Standing for Privacy Enhanced Mail, PEM files are primarily used to store cryptographic keys, certificates, and other data necessary for securing communications.

Mutual Authentication: The Keystone of Zero Trust

Mutual Authentication serves as a fundamental component of the Zero Trust security model, a paradigm shift in the cybersecurity landscape that assumes no implicit trust is given to systems or users, regardless of their location or network. Instead, trust must be continuously verified. In this context, Mutual Authentication is not just beneficial—it's essential.

Securing Connections with mTLS: Smallstep's Approach

Mutual TLS (mTLS) strengthens the security of data transmissions by requiring both client and server in an exchange to authenticate each other's identities before establishing a connection. This two-way verification process not only confirms that the entities involved are who they claim to be but also lays the groundwork for a secure communication channel, adding an extra layer of trust and integrity to digital interactions.

Why Device Attestation Rules the Roost

Device identities come in various forms, but not all are created equal when it comes to securing digital ecosystems. Password-based methods, hardware tokens, and digital certificates are common, but each has its limitations. Enter device attestation—a method that provides a more comprehensive security approach by verifying the integrity of the device itself, rather than just the identity of the user or the validity of a token.
