Network Appliance
A dedicated hardware device with pre-installed software for specific networking services like security, data storage or server functions inside of a nework infrastructure
Different Types of Network Appliances
Load Balancers
Crucial component in any high-availability network or system that is designed to distribute network or application traffic across multiple servers
● Enhance server efficiency and prevent overload
● Ensure redundancy and reliability
● Perform continuous health checks
● Application Delivery Controllers (ADCs) offer advanced functionality like SSL termination, HTTP Compression and Content Caching
● Essential for high-demand environments and high-traffic websites
Different Types of Network Appliances
Proxy Servers
Intermideiary between a client and a server to provide various functions like content caching, request filtering and login management
● Enhance request speed and reduce bandwidth usage
● Add a security layer and enforce network utilization policies
● Protect against DDoS attacks
● Facilitate load balancing and user authentication
● Handle data encryption and ensure compliance with data sovereignty laws
Different Types of Network Appliances
Sensors
Network sensors are designed to monitor, detect and analyse traffic and data flow across the network
in order to identify any unusual activities, potential security breaches or performance issues.
● Provide real-time insights for proactive network management
● Aid in performance monitoring and alerting
● Act as the first line of defense against cyber threats
Different Types of Network Appliances
Jump Servers/Jump Box
A jump server, also known as a jump box, is a dedicated gateway used by system administrators to securely access devices located in different security zones within your network.
● Control access and reduce the attack surface area
● Offer protection against downtime and data breaches
● Simplify logging and auditing
● Speed up incident response during cyber-attacks
● Streamline system management and maintenance
● Host essential tools and scripts
● Monitor system health for performance and security
