You may have heard about a data breach at a major cell phone company that compromised the personal data of approximately 40 million customers. According to reports, hackers disclosed 18.8 billion records in the first six months of 2021. According to Reuters, the seller provided data on 30 million mobile phone victims for 6 Bitcoin, or around $270,000. Later reports indicated that the asking price had dropped, and the entire data cache was unloaded for only $200.

Individuals have grown accustomed to losing their privacy and becoming tired of personal data dumps due to data theft; therefore, people must understand how to protect industries’ data or network security systems from criminals. Businesses and other critical operations institutions are taking cybersecurity very seriously, and that is why Cybersecurity Experts are in higher demand than ever.

What is Network Security?

Network security is a collection of rules that use software and hardware to secure the confidentiality, accuracy, and accessibility of computer networks and data. Because the threat environment is constantly changing and attackers always find and exploit flaws, every company uses Network Security to protect our data from ever-growing cyber threats.

What is the Purpose of Network Security?

The purpose of network security is to safeguard computer networks from unauthorized access, theft, misuse, modification, destruction, and other malicious activities that can compromise the confidentiality, availability, and integrity of resources and data. Network security aims to create a secure and safe environment for the network's users, data, and resources. It involves a range of measures, technologies, and best practices designed to prevent, detect, and respond to security threats and attacks. A network security breach may lead to hefty financial losses, harm to one's reputation, and possibly legal ramifications. Therefore, network security is critical to any organization's overall security posture and should be given due attention and resources.
