In this article, we will cover the important applications of cyber security and the importance of securing cyberspaces. We will also touch upon the various challenges that cyber security faces and the different types of cyber security threats.
Organizations are facing complicated problems when it comes to protecting their data and IT infrastructure. Owing to the massive rise of cybercrime, it is essential to implement good cyber security protocols and methods. Securing data, software, cloud systems, networks, and other digital assets is of prime focus now.
Companies heavily rely on IT infrastructure and the internet for their daily activities. This is one of the primary reasons why securing the IT infrastructure is so important. Getting hacked results in compromise of data, loss of customer trust, and obviously financial loss. Add to this, it also leads to data theft, blackmailing, bankruptcy, and a complete shutdown of operations.
More than anything, companies must protect sensitive information from competition or market enemies in order to protect their future products and business strategies. Gaining access to company data can compromise years of hard work. More and more organizations have started shifting to cloud systems and databases in modern times, becoming even more vulnerable to various types of cyberattacks and hackers.
This is why it is absolutely necessary to employ good cyber security strategies and put holistic cyber security measures in place in order to prevent data leaks and infrastructure sabotage. Once hackers are inside the systems or systems are infected, anything can be extracted or manipulated by the threats, thus leading to a loss of data integrity as well.

Cyber Security – Overview
Cyber security can be defined as a process of protecting computers, networks, servers, programs, and other electronic systems from malicious attacks. This domain also deals with recovering the said networks, data, programs, and computers after the attack as well. The methods associated with cyber security help defend businesses against threats that are trying to destroy, access, alter, or extract business information. Cyber security ensures the integrity of data, and also that data flow or business operation is not interrupted by cyberattacks.
The field of cyber security also deals with authentication, authorization management, and monitoring. Most of the methods employed in this domain are used with the notion that prevention is always better than cure. This is true as early detection of threats or predicting attacks can prevent thousands or even millions in recovery costs.
Hackers are getting increasingly more innovative and using more non-traditional methods such as Artificial Intelligence and Social Engineering to gain access to systems and data. These attacks are also becoming more frequent and being assisted by powerful malware, spyware, and other viruses. It is not just these kinds of threats that cyber security must deal with though, but the field must also deal with scanning infrastructure, programs, and networks to find defects that can allow security to be compromised.
There can also be glitches or loopholes that hackers can take advantage of to gain entry into the system or create make-shift access points. Cyber security also deals with guidelines that should be followed and the education of employees to do their part in protecting their organization from both internal and external threats. For example, not leaving your computer unlocked as someone else can get access to it or not clicking on suspicious links sent by unknown individuals that can download a program into your system.
Cyber security protects:
- Users or Individuals
- Data, Operations, and Processes
- Devices, Networks, and Technology
Different Types of Cyber Security Threats
Cyber security threats can appear anywhere at any time. These attacks can be commissioned or carried out by business rivals, cyberterrorists, industrial spies, criminal groups, ex-employees, or unhappy employees. These threats can even arise due to political agendas or other foreign deep state reasons.
Here are the different types of cyber security threats:
- Spyware, ransomware, worms, viruses and other malware

Important Applications of Cyber Security
When talking about the various applications of cyber security in real life, we, by default, always think about locking our systems when needed and using strong passwords and antiviruses. However, when talking about the applications of cyber security in companies and IT infrastructure, there are multiple security requirements that various cyber security methods serve. These requirements can range from monitoring, authentication, threat prevention, recovery, and data protection, thus requiring a holistic set of methods and frameworks to tackle every vector or source of security threats.
The important applications of cyber security are as follows:
- Access Control: In this application, authentication, authorization, and monitoring are focused upon. Here, professionals must use cyber security methodologies and frameworks to limit users and assign roles. Also, suspicious activities must be tracked and monitored extensively in order to stop unauthorized access or activities.
- Telecommunications and Network Security: Information and communication confidentially are protected. The main focus of this application is to protect data and ensure the flowing availability of data. Networks are secured and reinforced while it is made sure that telecommunications are not compromised.
- Information Security Governance and Risk Management: This application of cyber security deals with risk management, security governance, data integrity, security education, and risk analysis. Risk management has a lot to do with risk assessment and control of the damage that can be caused by these risks. Information security also deals with the integrity of sensitive information.
