Secure Internal Websites with HTTPS

A.

This is a way to update all internal sites without incurring additional costs? To be a CA (Certificate Authority), you need an infrastructure that consists of considerable operational elements, hardware, software, policy frameworks and practice statements, auditing, security infrastructure and personnel.

The best solution for the network administrator to secure each internal website is to use certificates signed by the company CA (Certificate Authority).

Explanation: HTTPS (Hypertext Transfer Protocol Secure) is the secure version of HTTP, which is the protocol used for communication between web browsers and web servers. HTTPS ensures that all communication between a user's browser and a web server is encrypted, making it more secure against eavesdropping and tampering.

Certificates are used to establish the identity of the web server to the client's browser. When a browser connects to a website using HTTPS, the server presents a certificate to the browser to verify its identity. The certificate includes information about the website, such as its domain name and public key.

In this scenario, the CSO has issued a new policy that requires all internal websites to be configured for HTTPS traffic only. To achieve this, the network administrator needs to obtain a certificate for each internal website.

Option A: Use certificates signed by the company CA Using certificates signed by the company CA is the best solution because it ensures that the certificates are trusted by all internal clients. A company CA is a trusted entity within the organization that issues digital certificates for internal use. By using certificates signed by the company CA, the network administrator can ensure that each internal website has a valid certificate that is trusted by all internal clients.

Option B: Use a signing certificate as a wild card certificate Using a signing certificate as a wild card certificate is not a good solution because it introduces security risks. A wild card certificate is a certificate that is valid for multiple subdomains of a domain. Using a signing certificate as a wild card certificate means that all subdomains share the same private key, which makes it easier for an attacker to compromise the entire domain.

Option C: Use certificates signed by a public CA Using certificates signed by a public CA is not a good solution because it can incur additional costs. Public CAs charge for issuing certificates, and the cost can add up quickly for each internal website.

Option D: Use a self-signed certificate on each internal server Using a self-signed certificate on each internal server is not a good solution because it can create trust issues with internal clients. Self-signed certificates are not trusted by default, which means that users will see a warning message when they visit an internal website with a self-signed certificate. This can create confusion and distrust among users, and it may cause them to avoid using internal websites altogether.

In conclusion, the best solution for the network administrator to secure each internal website is to use certificates signed by the company CA. This solution ensures that each internal website has a valid certificate that is trusted by all internal clients, without incurring additional costs or introducing security risks.
