Digital Forensics

Digital forensics is the process of gathering, preserving and analyzing data from a computer system and/or network for use as evidence in a legal procedure. It can be challenging to properly collect relevant evidence while complying with the rules of evidence in order to ensure that such collected evidence is admissible in court.

DLP (Data Loss Prevention)

DLP is a set of security mechanisms that prevent data loss or leakage. It includes strict access controls, blocking email attachments, network file exchange, cut-and-paste, social networks, and encrypting stored data.

DMZ (Demilitarized Zone)

A DMZ is a segment of a private network that is isolated from the private network using a firewall and is protected from obvious abuses and attacks from the Internet using a firewall. There are two main configurations for deploying a DMZ: screened subnet and multi-homed firewall.

DOS (Denial of Service)

A DoS (Denial-of-Service) attack aims to disrupt access to a resource. It violates availability. Flooding, connection exhaustion, and resource demand are the types of DoS attacks. A flooding attack overloads network devices and servers with massive network traffic. Connection exhaustion consumes all system resources related to connections, preventing other connections. Resource demand repeatedly requests a resource, keeping the server too busy to respond to other requests.

Encryption Key

A key is a secret number used to control encryption and decryption. The length of the key determines the key space and provides more security against confidentiality breaches.
