Role of Communication Networks in Internal Security

Introduction

Effective communication networks are critical for preserving internal security. Communication networks facilitate the interconnection of communicating through electronic devices such as computers, laptops, mobile phones, and telephones that allows executives to send important and confidential information from all other sectors, such as voice, data, video, and internet networks. Computer networks such as Local area networks and Wide-area networks should not be confused with communication networks because they are only one form of a communication network. 

• Effective communication networks are critical for preserving internal security. As a result, communications systems play an important role in internal and external security as well as emergency preparedness. 
• Furthermore, communication networks are heavily reliant on one another in a complex manner. If one communication network fails, it might have a negative impact on other industries. 
• Severe security threats, such as data breaches, frauds, denial of service (dos), hacking and cyberwar, terrorist and anti-national crimes, may occur in communication networks. 
• A cyber-attack that can take control of the infrastructure could cause the system to malfunction and the communication network to be disrupted. 
• Viruses, malware, Trojan horses, hacking, network scanning, probing, and phishing are all possible methods of attack. 
• Furthermore, social network attacks may become a major source of attacks in the future due to the large number of people who utilise these networks to submit personal information on websites.
