Today, you will be learning about the following topics in Cyber Security as well as its scope as a career. The blog will cover the all types of cyber security tactics, some of the popular tools used, and more.
What is Cyber Security? Learn here in detail:
Any individual or organization should be aware of their valuable assets that are present in their system or network and identify the threats that risk those assets being lost or damaged should they get into the wrong hands.
What is Cyber Security?
Cyber Security is about adding layers of security to computers, devices, systems, and networks to stop attacks. Almost all organizations have a system and framework to deal with cyberattacks, whether they are attempted or successful. A good framework can help detect and identify threats, protect networks and systems, and recover in case any attack was successful.

Types of Cyber Security
Let’s now break down the different types of Cyber Security.
- Database and Infrastructure Security: Considering the fact that everything in a network includes physical equipment and databases, securing these devices is vital. Database and infrastructure security is for these cyber-physical systems, which may include even water purification systems and electricity grids.
- Network Security: Network security covers numerous technologies, devices, and processes. It involves a designed set of rules and configurations implemented for the protection of the confidentiality, integrity, and accessibility of networks and data.
Network security is intended to protect internal networks from attackers by securing the infrastructure. The implementation of new, strong passwords and two-factor authentication (2FA) are perfect examples of network security.
- Application Security: Application security uses software and hardware for the protection and security against threats that may crop up during the development stage of an application. For example, firewalls, antivirus programs, encryption, etc. are kinds of application security.
- Information Security: Information security or InfoSec helps in preventing unauthorized access, disruption, disclosure, misuse, modification, inspection, destruction, recording, or any other kind of malintent involving sensitive data or information.
Information security is typically built around three objectives—CIA (confidentiality, integrity, and availability)—and aims to protect both physical and digital information in any form.
- Cloud Security: Cloud security refers to the technologies, services, controls, and policies that aim to provide protection for cloud data, infrastructure, and applications from cyber threats and attacks. It helps to do away with any risks that are associated with on-premises attacks by constantly protecting and monitoring the data in the cloud.
- Data Loss Prevention: Data loss prevention focuses on coming up with processes and policies designed to prevent and handle data loss, as well as recovery policies as a countermeasure for successful Cyber Security breaches. Data loss prevention involves having network permissions and policies in place for data storage.
- End-user Education: End-user education is the process of educating and training users about the best security practices and safety measures (e.g., not to click on unknown links, not to download suspicious attachments received in emails, etc.) to avoid letting in malware or other malicious software.
A good end-user security training program can help enhance the security in an organization when done properly. The training should be in a language and at a technical level that can be understood and followed by everyone.
- Identity Management and Access Control: Identity management and access control can be crucial components in a security architecture, and it basically involves the management of access to enterprise resources. This is a good measure that can ensure the security of systems and data. This type of security helps in the verification of users’ identities before granting them access to the systems and sharing information with them.
- Mobile Security: Mobile security, also known as wireless security, is the protection that is in place for smartphones, laptops, tablets, and other portable devices and the networks they are connected to from the threats and risks that are involved in wireless computing.
- Disaster Recovery or Business Continuity Planning: Disaster recovery is the process of resuming business after a disruptive event. Business continuity planning, on the other hand, ensures that enterprises can keep running the business and capitalize not only after small disruptions but also in the event of bigger disasters. Because of their many common considerations, the two terms are often mentioned under the acronym BC/DR.
All BC/DR plans are mapped out to help employees communicate and go about doing their jobs in the event of an attack. The details of a BC/DR plan may vary depending on the size, scope, and workings of the company. Also, it is crucial to understand that physical, HR, and IT plans cannot be developed independently of each other in this case.

Importance of Cybersecurity
Cybersecurity is even more significant now as most things that we enjoy today are in the form of connected devices and systems. With IoT revolutionizing the way the world operates, it has become imperative that Cybersecurity be implemented in all systems that are prone to threats and attacks to prevent extortion attempts, identity theft, loss of valuable data, misuse of sensitive information, cyberstalking, etc.
Critical infrastructures such as hospitals, financial service companies, power plants, etc. possess sensitive data not only pertaining to their consumers but also to themselves. This calls for serious consideration for Cyber Security implementation to keep our society functioning without disruptions.
Cyber Threat Researchers, in this regard, uncover new vulnerabilities, strengthen open-source tools, and educate people on the importance of cybersecurity.

Challenges in Cyber Security
The biggest challenge faced by companies in Cyber Security is the implementation of effective cybersecurity measures due to the ever-evolving nature of risks. It is as if there are more devices than people in this world today, and attackers are becoming more and more creative.
Organizations and the government’s security endeavors taken for only the most crucial system components have proved to be insufficient with more advanced and evolved threats on the loose. Thus, there is a necessity for organizations to adopt more proactive and adaptive approaches to Cyber Security.
Unlike the traditional approach, the National Institute of Standards and Technology (NIST) recommends a shift toward real-time assessments and continuous monitoring, thus making security more data-oriented.
