What Is Cybersecurity -The practise of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks is known as cyber security. It is also referred to as information technology security or electronic data security. The term is used in a variety of contexts, ranging from business to mobile computing, and can be classified into a few broad categories.
- Network security is the practise of defending a computer network against intruders, whether they are targeted attackers or opportunistic malware.
- Application security is concerned with keeping software and devices safe from threats. A compromised application may allow access to the data it is supposed to protect. Security starts in the design stage, long before a programme or device is deployed.
- Information security safeguards the integrity and privacy of data while it is in storage and transit.
- The processes and decisions for handling and protecting data assets are included in operational security. This includes the permissions that users have when connecting to a network as well as the procedures that govern how and where data can be stored or shared.
- Disaster recovery and business continuity define how a company responds to a cyber-security incident or any other event that results in the loss of operations or data. Disaster recovery policies govern how an organisation restores its operations and information in order to resume normal operations following a disaster. Business continuity is the plan that an organisation uses when it is unable to operate due to a lack of resources.
- End-user education addresses the most unpredictable factor in cyber security: people. By failing to follow good security practises, anyone can introduce a virus into an otherwise secure system. Teaching users to delete suspicious email attachments, not to plug in unidentified USB drives, and a variety of other important lessons is critical for any organization’s security.
What Is Cybersecurity Threats
What Is Cybersecurity counters three types of threats:
- Single actors or groups targeting systems for financial gain or disruption are examples of cybercrime.
- Cyber-attacks frequently involve the collection of politically motivated information.
- Cyberterrorism aims to disrupt electronic systems in order to cause panic or fear.
- So, how do bad actors gain access to computer systems? Here are some common methods for jeopardising cyber-security.
What Is Cybersecurity And Cyber Attacks Types
A virus is a self-replicating programme that attaches to clean files and spreads throughout a computer system, infecting files with malicious code.
These are a type of malware that masquerades as legitimate software. Cybercriminals trick users into downloading Trojans that cause damage or collect data on their computers.
A programme that secretly records what a user does in order for cybercriminals to use this information. For example, spyware could record credit card information.
Malware that encrypts a user’s files and data and threatens to delete it unless a ransom is paid.
This is advertising software that can be used to spread malware.
Networks of malware-infected computers used by cybercriminals to perform online tasks without the user’s permission.
Phishing occurs when cybercriminals send emails that appear to be from a legitimate company and request sensitive information from victims. Phishing attacks are frequently used to trick people into providing credit card information and other personal information.
Attack with a man-in-the-middle
A man-in-the-middle cyber threat occurs when a cybercriminal intercepts communication between two people in order to steal data. On an insecure WiFi network, for example, an attacker could intercept data passing between the victim’s device and the network.
A distributed denial-of-service attack
A denial-of-service attack occurs when cybercriminals overload networks and servers with traffic, preventing legitimate requests from being fulfilled. This renders the system inoperable and prevents an organisation from performing critical functions.
