This involves keeping communications secure between a client and server or a client and another client. Digital signatures for documents — Certificates can also be used as digital signatures for documents. Digitally signing a document lets the recipient of the document know that the signer has sent the document and that there is nothing malicious within the document. Code signing — Code signing with certificates is very similar to document signing.

When code is created, the code designer signs the code to verify they have created it and that no malicious code is hidden within. Client-server authentication — Client-server authentication verifies the identity of both the client and server to the other party of the communication.

Key elements to setup your own PKI. Identify your certificate requirements — You must first identify all current and future requirements for digital certificates. This refers to what your certificates within your PKI are, and will, be used for. Selecting the Right Certificate Authority — Based upon your requirements, you must select the type of Certificate Authority you want to setup. If you are typically using your PKI to support your enterprise requirements, which are mostly based on Microsoft services, then setting up a Microsoft CA would be a good option for your organization.

More and more often, however, applications and services are migrating to the Cloud, so it is important to support Cloud requirements. In situations where the majority of services and products are on the Cloud, it is important to ensure that the CA you are setting up supports Cloud-based requirements.

Certificate Management — Just setting up an internal PKI infrastructure does not ensure that your organization will be able to meet and manage all PKI-related requirements. One of the most important requirements of a PKI infrastructure is automating certificate management operations. This ensures all certificate operations necessary are quick to be completed and human error will not effect them. As such, it is important that these private keys are stored securely on an HSM.

These documents also act as the framework and scope of your Certificate Authority, telling it to whom it can issue certificates, what the boundaries within which the CA will work are, and the procedures used to manage your CA.

Certificate revocation and CRL checking — One more important step in creating your PKI is ensuring that certificates are revoked when necessary, and that when they are revoked, they are placed into the CRL. It is also important to have your CAs regularly check for new CRLs, allowing them to be up-to-date on the latest revoked certificates. Basic Architectures. Two-Tier Architecture. A two-tier architecture is the most common form of PKI hierarchy, and also the most balanced architecture.

The below image shows how the setup of a two-tier PKI looks. The design of a two-tier PKI architecture works with security and simplicity in mind, allowing the root of trust, the Root CA, to stay offline, protecting it from attack.

Since the Root CA cannot be compromised, there is no worry that certificates are being misused or given to untrusted users. Instead of the Root CA giving out certificates, it creates the certificates for its original Issuing CAs, and allows them to to issue certificates to end-users. Two-tier PKI architectures are the most common type of hierarchy used.

Three-Tier architecture. The Intermediary CAs add another layer to the certification path, allowing users to see one more CA in the chain of trust. The three-tier architecture is the most secure, as there are more links in the chain that would need to be compromised by attackers.

However, setting up a three-tier architecture is a much more complicated process than setting up a two-tier architecture.

A three-tier architecture is used much less often than a two-tier architecture. Common Deployment Mistakes. Lack of planning and tracking: One of the more common mistakes with a PKI is the lack of planning and tracking. Poor planning can also lead to poor certificate and key management, offering another avenue for attackers to exploit. Along with planning, poorly tracking PKI assets can also cause issues. If certificates are compromised or left unused, malicious users could use the certificates to steal or access sensitive data.

Proper automation and monitoring of the certificate lifecycle can stop this mistake from occurring. PKI as a Service. The way PKI as a Service works is that a provider will have the PKI setup, whether at their own data center or within your organization, and handle all of the management and updating in the PKI.

This allows the organizations purchasing this service to not need to train or hire PKI professionals, thus saving them money and manpower. We assist your organization in the design, implementation, and deployment of your PKI. We can implement it in our data center in Dallas, Texas, or onto your site. Whichever hardware security module you choose to use, they are all FIPS Level 2 and 3 compliant, so you should reach all of your compliance requirements.

Along with an HSM, we also help you build and design a backup for your PKI, for minimal to no loss of service from unseen circumstances. We can also implement different SIEM tools into your PKI, allowing you to monitor certificates and keys, to keep you up to date on revoked certificates, unused keys, etc. Subscribe to.
