Types of networks:
1) Personal network (Cell phone, Social networking like Facebook, Whatsapp, Instagram,Twitter)
2) Private network (Company network )
3) Government network ( Officer’s network )
4) Underworld network ( Mumbai underworld )
Networks are prone to be insecure as human beings are prone to cheating.
Trust grows with time and trustworthiness of people (past record). So Multilevel privileges are the only way to make networks safer.
Networks are split into smaller groups and each group understands what they should understand when the same communication is made to the whole network.
Every network is recorded in communication media and monitored. So Theres no possibility of 100 % confidential networks. If at all its present it will be destroyed by the system if its anti-social.
