It can be implemented as hardware, software, or a combination of both. Some of the important security technologies used in the cybersecurity are described below- Firewallįirewall is a computer network security system designed to prevent unauthorized access to or from a private network. Most security is based on one of these types of things: something we have (like a key or an ID card), something we know (like a PIN or a password), or something we are (like a fingerprint).

The fact that the information and tools & technologies needed to penetrate the security of corporate organization networks are widely available has increased that security concern. With the rapid growth in the Internet, cybersecurity has become a major concern to organizations throughout the world.
