What is Cyber Security And How They Work?

Cyber security refers to the collection of methodologies, technologies, and processes used to safeguard the confidentiality, integrity, and availability of computer systems, networks, and data from cyber-attacks or unauthorised access. The primary goal of cyber security is to safeguard all organisational assets from both external and internal threats, as well as natural disaster-related disruptions.

The technique of protecting computers, servers, mobile devices, electronic systems, networks, and data from hostile intrusions is known as cybersecurity. It’s also known as electronic information security or information technology security. The phrase is used in a range of contexts, ranging from business to mobile computing, and it may be broken down into a few categories.

Network security: The practise of guarding a computer network from intruders, whether targeted attackers or opportunistic malware, is known as network security.

Application security: Application security is concerned with ensuring that software and devices are free of dangers. A hacked application could allow access to the data it was supposed to secure. Security starts throughout the design phase, long before a programme or device is deployed.

Information security: Data integrity and privacy are protected by information security, both in storage and in transport.

Operational security: The processes and decisions for handling and securing data assets are included in operational security. The protocols that dictate how and where data may be kept or exchanged, as well as the permissions users have while accessing a network, all fall under this umbrella.

Disaster recovery and business continuity: Disaster recovery and business continuity are terms used to describe how a company reacts in the case of a cyber-security breach or any other catastrophe that results in the loss of operations or data. Disaster recovery policies define how an organisation returns operations and information to the same operational capabilities as before the 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: People are the most unexpected aspect in cyber-security, hence end-user education is critical. By failing to follow appropriate security measures, anyone can put a virus into a system that is otherwise secure. It is critical for any organization’s security to teach users how to discard suspicious email attachments, not to plug in unfamiliar USB drives, and other crucial lessons.

Different types of cyber-threats

Cyber-security counters three types of threats:

1. Cybercrime refers to individuals or groups who attack systems for monetary gain or to cause disruption.

2. Politically motivated information collection is common in cyber-attacks.

3. The goal of cyberterrorism is to generate panic or dread by undermining electronic systems.

Cyber-Attacks: What They Are and How They Work

Cyber threats come in a variety of forms and kinds. Some are overt ransomware assaults (hijacking critical company products or tools in exchange for money to unlock them), while others are stealthy operations in which criminals infiltrate a system to steal vital data, only to be detected months later, if at all. Criminals are becoming more sophisticated in their acts, and here are some of the most common sorts of cyber attacks that harm thousands of individuals every day.

Malware is a type of malicious software that can

Spyware, ransomware, and viruses are examples of malevolent software. It usually infiltrates networks by exploiting a flaw, such as clicking on phishing emails or installing a dangerous application. Malware can gather sensitive information once within a network, develop additional destructive software throughout the system, and even prevent access to critical corporate network components (ransomware).

Phishing is a type of online fraud.

Phishing is the technique of delivering harmful messages (typically emails) that appear to come from well-known and trusted sources. To assuage doubts and persuade recipients to click on hazardous links, these emails imitate the same names, logos, phrasing, and other elements as a CEO or firm. When a phishing link is clicked, cyber criminals gain access to sensitive information such as credit card numbers, social security numbers, or login credentials.

Social Engineering is a term that refers to 

The process of mentally manipulating someone into giving personal information is known as social engineering. Phishing is a type of social engineering in which criminals use people’s natural curiosity or trust to their advantage. Voice manipulation is an example of more advanced social engineering. In this example, cyber fraudsters use a person’s voice (from sources such as a voicemail or a social media post) to phone friends or family and request credit card or other personal information.

Attack by a Man-in-the-Middle

Man-in-the-Middle (MitM) attacks occur when criminals interfere with a two-party transaction’s traffic. Criminals, for example, can place themselves between a public Wi-Fi network and a user’s device. Cyber crooks can occasionally read all of a victim’s information without ever being discovered if they don’t have access to a secure Wi-Fi connection.

Attack on a zero-day basis

Zero-day assaults are on the rise. In essence, these assaults occur between the announcement of a network vulnerability and the application of a patch solution. Most firms will report that they have discovered a flaw with their network security in the name of transparency and security, but some criminals will seize the chance to launch attacks before the firm can provide a security fix.

What is the distinction between a cyber-attack and a data breach?

A cyber-attack differs from a security breach in several ways. A cyber-attack, as defined above, is an attempt to compromise a system’s security. Using various types of cyber-attacks as detailed in the preceding section, attackers attempt to exploit the confidentiality, integrity, or availability of a software or network. A successful event or occurrence in which a cyber-attack results in the compromise of sensitive information, unauthorised access to IT systems, or service disruption is known as a security breach.

Attackers regularly try a variety of cyber-attacks on their targets in the hopes that one of them would result in a security breach. As a result, security breaches draw attention to another important aspect of a comprehensive cyber security strategy: business continuity and incident response (BC-IR). In the event of a successful cyber-attack, BC-IR assists an organisation in dealing with the situation. When a security incident occurs, Business Continuity is concerned with keeping important business systems online, whereas Incidence Response is concerned with responding to a security breach and limiting its effects, as well as aiding the recovery of IT and business systems.
