Egress Filter
Egress Filter: A network security measure that monitors and restricts the flow of outbound traffic from one network to another. Typically implemented in firewalls or routers, egress filtering rules ensure that only authorized data leaves the network, helping to prevent data exfiltration and stop the spread of malware. It’s essential for enforcing network security policies […]
Encapsulation
Encapsulation: In computer networking, encapsulation refers to the process of wrapping data with necessary protocol information before network transmission. Similar to an envelope for a letter, it involves adding headers (and sometimes trailers) around data for proper delivery and processing. In object-oriented programming, encapsulation is a fundamental concept that binds together the data and functions […]
Dynamic Host Configuration Protocol (DHCP)
Dynamic Host Configuration Protocol (DHCP): A network management protocol used on IP networks where a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on the network so they can communicate with other IP networks. DHCP eliminates the need for manually assigning IP addresses to all network devices, simplifying […]
Dynamic Link Libraries (DLLs)
Dynamic Link Libraries (DLLs): Modular files containing code and data that can be used by multiple applications simultaneously. DLLs allow for code reuse, modularization, and memory efficiency as the same library can serve multiple applications, reducing the need for redundant code. Their misuse or manipulation could lead to potential security vulnerabilities such as DLL hijacking […]
Dynamic Packet Filtering
Dynamic Packet Filtering: A security measure used in network firewalls to manage the flow of network traffic in real-time. Unlike static packet filtering, which only examines a packet based on predefined rules, dynamic packet filtering evaluates packet information within the context of the packet’s state or connection, providing a more adaptive and sophisticated approach to […]
Dynamic Partitioning
Dynamic Partitioning: In computing, it’s a method of dividing a hard drive or a database into segments that can be easily modified in size. This allows for the efficient use of space and resources by allocating and deallocating partitions as needed, without the need for a static predefined partition size. Dynamic partitioning can improve performance […]
