Question

what non cryptographic technique we use to protect data in future

Answer 1

The non-cryptographic technique that must be used for protecting data in the future is as follow:

Port Security:

Maintaining the ports according to the needs is one of the most important things which one should consider while listing down the systems to be secure. As it is going to be one of the most important and major parts of port security.

There are certain steps which one should follow for port security which I believe works for every organization:

• Limiting the number of devices on most of the switch ports is to be done in each organization.
• Also using MAC ADDRESSES in the organization must be limited to a certain level of work procedure.

Now, coming to the techniques in securing ports are as follows:

• Making Use of Dynamic MAC Addresses:
  • It becomes important to dynamically configure and also secure the MAC addresses of the devices which are been connected to the certain ports.
  • The addresses must always be stored in the address table so as to keep the data secure and also in working mode.
  • In this technique, we also stay away from forwarding traffic from unspecified devices or devices which are not known to the network.
• Using Static MAC Addresses:
  • It is one of the most useful methods as it secures the MAC addresses by statically configuring each of them with the switch port.
  • The MAC Addresses are also stored in the address table.
  • The static configuration of the network is been stored by default while using port security.
  • The table which stores addresses can be made permanent by actually saving them to the startup configuration.
• Using Sticky MAC Addresses:
  • In this, a technique the MAC addresses are used as hybrid addresses which are being dynamically learned from most of the devices which are being connected with the switch port.
  • The addresses are also being put in the address table and are also been entered into most of the running configuration that is static secure MAC addresses.
  • The MAC addresses are also lost if they are not saved in the startup configurations.

Hence, this is the non-cryptographic technique that is going to be used for protecting data in the future.
