The firewall

It is located in the network gateway and is used to define the rules by which resource users can access inside and outside and by which protocols.

Network Access Control-NAC

Network access control technology, instead of identifying devices in the system and preventing or allowing them to be included in the network at the backbone key level, perceives which devices (PC, laptop, smartphone, etc.) are trying to access corporate resources and from which location (business, home, cafe, etc.). It includes solutions to determine access privileges accordingly.

Attack Prevention System-IPS

Attacks to the network from outside or inside cause data loss as well as making systems inaccessible. An example of this type of attack is to make the bandwidth of the institutions unusable due to heavy traffic by attacks made over the botnet networks formed by millions of users. Intrusion prevention systems send a large number of requests to servers to prevent attacks that render servers inoperable.
