A Server Certificate is digital certificate used to identify the server to clients when they connect. The public and private keys associated with the server certificate are also used to encrypt the SSL session key information. Public key lengths of at least 768 bits must be used to be considered secure.
Which of the following is an enhanced type of domain digital certificate ? A certificate repository (CR) is a publicly accessible centralized directory of digital certificates . True. A Subject Alternative Name (SAN) digital certificate , is also known as a Unified Communications Certificate (UCC).
” What common method is used to ensure the security and integrity of a root CA ? – Keep it in an offline state from the network.
A digital certificate is a technology used to associate a user’s identity to a private key. A user electronically signs a Certificate Signing Request (CSR) by affixing their public key and then sending it to an intermediate certificate authority. False. Root digital certificates are should never be self-signed.
What should never be included in a digital certificate ? A) The digital signature of the certificate authority (CA) that has issued the digital certificate . B) The private key of the party to whom the digital certificate is tied. C) The identity of the party that owns the digital certificate .
In addition to protecting data in-use and data at-rest, cryptography is most often used to protect data in- transit across a network. One of the most common transport cryptographic algorithms is Secure Sockets Layer (SSL).

What common method is used to ensure the security and integrity of a root CA ? Keep it in an offline state from the network. What is a value that can be used to ensure that plaintext, when hashed, will not consistently result in the same digest?
A SYN flood attack broadcasts a network request to multiple computers but changes the address from which the request came to the victim’s computer . Traditional network security devices can block traditional network attacks , but they cannot always block web application attacks .
In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS ) or, formerly, Secure Sockets Layer (SSL ). The protocol is therefore also referred to as HTTP over TLS, or HTTP over SSL.
A digital certificate is a digital form of identification, like a passport. A digital certificate is issued by a Certification Authority (CA). Examples of trusted CA across the world are Verisign, Entrust, etc. The CA guarantees the validity of the information in the certificate .
The main purpose of the digital certificate is to ensure that the public key contained in the certificate belongs to the entity to which the certificate was issued, in other words, to verify that a person sending a message is who he or she claims to be, and to then provide the message receiver with the means to encode
A digital certificate contains the public key information , along with a digital signature from a CA. It also includes information about the certificate , like the entity that the certificate was issued to.
