Is Kerberos safe?

Kerberos is far from obsolete and has proven itself an adequate security-access control protocol, despite attackers’ ability to crack it. The primary advantage of Kerberos is the ability to use strong encryption algorithms to protect passwords and authentication tickets.

Why Kerberos is needed?

Kerberos has two purposes: security and authentication. In addition, it is necessary to provide a means of authenticating users: any time a user requests a service, such as mail, they must prove their identity. … This is done with Kerberos, and this is why you get your mail and no one else’s.

What is Kerberos and how does it work?

Kerberos is a computer network security protocol that authenticates service requests between two or more trusted hosts across an untrusted network, like the internet. It uses secret-key cryptography and a trusted third party for authenticating client-server applications and verifying users’ identities.

What is meant by Kerberos?
