About Computer Networks and Information Security

A computer network is a mechanism by which computers in a small area or across the globe share information. The other term which is commonly associated with this is network security or information security. In general, information security can be called something that helps in transmitting data from one device to the other safely and securely. Or, computer security or information security can be called the protection of the device from any data theft, information disclosure, damage to the hardware or software, or the electronic data stored in them.

What is Computer Networks and Information Security?

The most common example of sharing information in a computer network is the internet which has access to nearly every device globally. This acts as a boon for everyone. Still, when we look at the negative parts, it opens a gateway for the attackers to infiltrate the information transmitted or stored in the device. Communication in a mobile ad hoc network consists of two phases, route discovery and data transfer. In an adverse environment, both steps are vulnerable to different attacks. To resolve and end such malpractices, a concept of network and information security was developed. Network security includes the strategies, procedures and practices adopted to prevent, detect, and monitor unauthorized access, abuse, modification, or denial of computer networks and access network resources. The most common attacks in the networks are software attacks. Ranging from malicious websites, injection of viruses into the systems to get the information or gaining control of the system, sending spam emails or developing phishing sites are examples of such attacks. The other attacks could be Identity Theft which is the attempt to act like an unconventional person to obtain that person's personal information or to take advantage of their access to critical information through social engineering. Attacks like these can be used to get information about any organization or any company. One of the recent worldwide attacks was ransomware. The attackers demanded a certain amount of money to release the systems from their hands. In such attacks, the victim is bound to pay the bounty because, in one click, the whole information can be made public or deleted.

Eligibility and Career in Computer Networks and Information Security

Candidates who have passed 12th grade with mathematics and science as compulsory. In today's world, attacks on the systems are widespread especially bypassing the system's security to retrieve or misuse the information. Because of this, demand for network security engineers has risen in the computer world. There are various undergraduate programs offered at colleges that teach about these attacks and how to overcome them. A good cybersecurity expert is always in demand for maintaining a secure environment for the employees in any company.
