Data encrypted using symmetric-key encryption is subject to corruption during transport.

Symmetric-key encryption operates slower than asymmetric-key encryption.

Polymorphic virus-based attack

Denial-of-service attack

Distributed denial-of-service attack

Man-in-the-middle attack using a packet sniffer

It is slow because it requires extensive calculations by the computer.

It can lead to the corruption of encrypted data during network transfer.

It is reliant on the Secure Sockets Layer (SSL) standard, which has been compromised.

It is difficult to transfer any portion of an asymmetric key securely.

HTTP uses cleartext transmission during authentication, which can lead to a man-in-the-middle attack.
