Key attributes of a VPC include:

• Private IP Addresses: Devices within a VPC are assigned private IP addresses, preventing direct internet access.
• Subnet Configuration: Users can segment their VPC into multiple subnets, each governed by unique rules and restrictions.
• Security Groups: VPCs empower users to define security groups, acting as virtual firewalls to control inbound and outbound traffic.

Decoding SSH: Secure Shell for Remote Access

Secure Shell (SSH) is a cryptographic network protocol designed for secure communication over unsecured networks. It establishes a secure channel for remote device access, safeguarding sensitive data during transmission.

How SSH Functions

SSH operates by encrypting data exchanged between a client and a server. This encryption ensures that intercepted data remains unreadable to unauthorized parties. Notable features of SSH include:

• Authentication: SSH supports diverse authentication methods, such as password-based and public key authentication.
• Encryption: SSH employs robust encryption algorithms to protect data during transmission.
• Tunneling: SSH facilitates the creation of secure tunnels for other protocols, including HTTP or FTP.
