The demand for Cybersecurity is still reaching its height and is creating many opportunities for programmers to grow in this field. Many industries take Cybersecurity on top of the priority table. It is to secure their data and any pieces of information regarding their developing and developed products. Therefore, it is also known as information security.

We all are aware that Cybersecurity is an international concern. There are cases where many pieces of information about the users’ data were leaked by taking advantage of the vulnerabilities in the system. To avoid such scenarios, you must know the methods to prevent them. You can attain knowledge regarding types of Cybersecurity through Great Learning Academy’s “Types of Cybersecurity” free course.
 

The definition of Cybersecurity is “ Cybersecurity is the set of principles and practices designed to protect our computing resources and online information against the threat.”

Cybersecurity can be categorized into network security, application security, information or data security, identity management, operational security, mobile security, cloud security, disaster recovery and business continuity planning, and user education regarding the threats.
 

You must have heard a lot about hacking. Hacking is a kind of cyber threat that steals data from the system and manipulates it. This can be considered a cyber-attack. To eliminate any uncertainties in your system, you should know about cybersecurity. The main objective of Cybersecurity is to ensure data protection. 
 

Cybersecurity follows the CIA triad principles. CIA refers to confidentiality, integrity, and availability. The CIA model is mainly followed to ensure security and helps design any security architecture for any organization.

Let’s now get familiar with a few of the Cyber threats. Types of cyber threats include Malware, Phishing, Man-in-the-middle attack, DDoS attack, Brute Force, SQL injection(SQLI), and DNS attack.

Malware: refers to malicious software, primarily a commonly used tool to hack into your computer or disrupt your working system. Some examples of malware are viruses, trojans, spyware, and ransomware.

Phishing: Phishing is a cybercrime where the attacker sends spoofed messages to the victim’s machine pretending to be a legitimate person or institution. He tricks the victim into giving up the sensitive information or implants malicious software into the victim’s machine. This results in the theft of personal data and financial loss.  

Man-in-the-middle attack: This attack happens when the invalid third party gets in between the two parties’ conversations or transactions, sends requests or responses as genuine users, and steals your data.

DDoS: A DDoS(Distributed Denial of Service) attack is a cyber-attack in which the attackers flood the network resource with many malicious requests. This exceeds the website’s capacity to handle the requests, and the host machine becomes unavailable for the intended users. Thus, it prevents some or all legitimate requests from being fulfilled.

Some benefits of Cybersecurity include the following:

1. Increased security of information: By implementing security measures, organizations can protect their critical data and information from unauthorized access and cyberattacks.

2. Improved reputation: Organizations that invest in cybersecurity can improve their reputation and trustworthiness in the eyes of their customers and partners.

3. Reduced costs: By preventing data breaches and cyberattacks, organizations can save on the costs associated with these incidents.
