Concept explainers

VLAN

VLAN stands for Virtual Local Area Network, and it is created from one or more local area networks. A Virtual Local Area Network (VLAN) is a customized network made up of one or more LANs. It allows a set of devices from different networks to be converted into a single logical network. As a result, a virtual LAN that is managed similarly to a physical LAN emerges.

The secure socket layer (SSL) protocol enables a client and a server to communicate securely. The SSLv2 protocol is known to have vulnerabilities. A man-in-the-middle attacker may push communication to a less secure level before attempting to decrypt the data. Encrypted communications may potentially be truncated by the attacker. SSLv3 has addressed these vulnerabilities (TLSv1). SSLv2 and SSLv3 are supported by the majority of servers and clients. For backward compatibility, SSLv2 is enabled by default. Please respond to the following questions. a) Determine the effect of the above statement. c) What is the answer to this problem? c) Do you believe SSLv3 is more secure than SSLv2? Justify your response.
