What is a replay attack? Describe the role of the sequence number field in a replay attack? Describe the Transport Layer Security (TLS) service in detail. Why is there a separate Change Cipher Spec Protocol, rather than including a change_cipher_spec message as part of the Handshake Protocol?

Network Security

The word "network security" refers to a wide range of technology, devices, and processes. In its most basic form, it is a combination of rules and configurations that use both hardware and software technologies to safeguard the confidentiality, integrity, and accessibility of computer networks and data. Every company, regardless of sector, size or infrastructure, needs network security solutions to protect itself from the ever-increasing landscape of cyber threats that exist today.
