What are the business benefits of using PKI? In the corporate environment, where any organization’s corporate processes need to be secured, it is highly important for both employees and clients to have a single sign-on system, in addition to electronic messaging and document securing systems Improving business processes by enabling time optimization, managing errors and reducing costs. Improving client and user satisfaction, enabling communications from anywhere and at any time. In the defence sector, data confidentiality and authenticity is particularly important. Stored data, e-mail messages and communications are encrypted with strong encryption algorithms and keys. In the health sector scenario, data access control and data protection are essential for supplying information concerning a patient’s health record, which is confidential. In the banking scenario, digital certificates are required to control clients’ access to their banking accounts and to digitally sign transaction orders. Why would a small business firm implement a PKI solution? The use of Public Key Infrastructure (PKI) can be an effective way to meet 1.business 2.regulatory 3.compliance requirements It is important to review the components of PKI before addressing requirements and solutions. The ease of installation, use, maintenance and cost of a PKI solution can help companies determine the solution that best meets their requirements. Steps in verifying a certificates validity : The PKI certificate path validation process happens automatically through the system to ensure each certificate in the chain is valid. This means that the system verifies that the certificate is active and has not expired, that the certificate has integrity and has not been altered or tampered with and that the certificate has not been revoked by the CA. The PKI certificate path validation relies on several different factors. This includes name chaining, where the certificates between the root certificate and the end certificate have to be issued from the named CA in the next immediate certificate. However, this is not the only issue that will be considered when completing the validation. Public keys are also used in the process through an Authority Key Identifier and a Subject Key Identifier. To establish a secure connection website require a certificate. Basically, these certificates have a Public key certificate which has a digital signature for them so that it can be trusted for the name, address, organization it has in the certificate by the client. In a typical public-key infrastructure (PKI) scheme, the signer is a certificate authority (CA), usually a company which charges customers to issue certificates for them. Browsers ensure user safety by requesting certificate information from the vendor instead of from the web application server. The job of a CA who issues the certificate is not to just issue the new certificate requests. It needs to provide the certificate revocation information for all the requests it is receiving from the clients. In this article, we will have a look at how certificate revocation works. Below are the types of certificate revocation check that can be configured CRL Distribution. - Certificate Revocation List. OCSP - Online Certificate Status Protocol. OCSP Staple. Both the configuration (CRL & OCSP) needs to be done on the certificate authority properties extension tab as shown below CRL distribution is the core component of the certificate revocation check.so the latter two options are indirectly and totally dependent on the CRL. The CRL configuration has components: Base CRL - This will contain the whole complete list of revoked certificates (non-expired). so whatever the revoked certificates we have will be present here. An example below of how it will show in the CRL and will show all the revoked certificates.
