What Is Cyber Security ? | Types of Cyber Attacks, Threats | How To Prevent Them

Cyber security is the protection of internet connected systems like hardware, software and data from cyber-threats. The practice is employed by individuals and enterprises to guard against unauthorized access to data centers and other computerized systems.

Cyber-attacks are often designed to access, delete, or extort an organization’s or users sensitive data; making cybersecurity important. Medical, government, corporate and financial organizations, may all hold vital personal information on a private, for instance. ( To know more about How to Recover Data Read Here )

Network security: – Network security is intended to protect your network and its data from multiple levels of security breaches and intrusions into hardware and software solutions. Network security may be a broad and overarching term that’s not only one but a broad term that’s wont to describe many various sorts of technology and various processes that are wont to define variety of rules and configurations associated with network usage, threats, Accessibility and general threat protection are used.

Application Security:– Application security focuses on protecting software and devices against threats A compromised application can provide access to the data it is supposed to protect Successful security begins in the design phase, long before a deployment is made. Program or device.

Operational security: – Operational security includes processes and decisions regarding the management and protection of data resources. The permissions that users have when accessing the network, and the procedures that govern how and where data can be stored or shared, fall within this scope.

Disaster recovery and business continuity:- Disaster recovery and business continuity define how a corporation responds to a cybersecurity incident or other event that leads to the loss of operations or data disaster recovery policies determine how the company restores its operations and information in order to restore the same operational capacity as before. The Business Continuity event is the blueprint on which the organization relies when trying to operate without certain resources.

End user training addresses the foremost unpredictable think about cybersecurity: People Anyone can accidentally introduce an epidemic into an otherwise secure system by not following good security practices. Important lessons are vital for the safety of any organization.

The scale of the cyber threat:

The global cyber threat is evolving rapidly and there is an increasing number of data breaches every year. A report by RiskBased Security found that a shocking 7.9 billion records were uncovered through data breaches in the first nine months of 2019 alone, which is more than double (112%) the number uncovered in the same period in 2018 Records. Medical services, retailers, and public institutions have the most violations, with malicious criminals responsible for most of the incidents Customer attacks are targeted.

With the dimensions of the cyber threat continued to grow, the International knowledge Corporation foretold that world payment on cybersecurity solutions can reach $ 133.7 billion by 2022. Organizations implement effective cybersecurity practices In the United States, the National Institute of Standards and Technology (NIST) has created a cybersecurity framework. To combat the proliferation of malicious code and facilitate early detection, the framework recommends real-time monitoring of all resources electronic. The importance of system watching is echoed within the “10 steps to cyber security”, steerage provided by the U.K. government’s National Cyber Security Centre.

In Australia, The Australian Cyber Security Centre(ACSC) frequently publishes steerage on however organizations will counter the newest cyber-security threats.

What is cyber Security? How to Prevent Cyber Attacks

Types of cyber threat

Common cyber threats:

  • Backdoors:

Backdoors allow remote access to computers or systems without user’s permission and user’s knowledge.

  • Formjacking:

Formjacking is that the method of inserting malicious JavaScript code into on-line payment forms so as to reap customers’ card details.

  • Cryptojacking:

Cryptojacking is that the malicious installation of cryptocurrency mining – or ‘cryptomining’ – software package. This software package illicitly harnesses the victim’s process power to mine for cryptocurrency.

  • DDoS attacks:

DDoS (distributed denial-of-service) attacks decide to disrupt normal internet traffic and take targeted websites offline by flooding systems, servers or networks with additional requests than they’ll handle, inflicting them to crash.

  • DNS poisoning attacks:

Domain name system poisoning attacks compromise domain name system to redirect traffic to malicious sites. Affected sites aren’t ‘hacked’ themselves.


Types of cyber attacks


Common Types of cyber attacks:


Botnets are large networks of compromised computers, whose processing power is employed without the user’s knowledge to hold out criminal activity. This will include distributing spam or phishing emails or completing DDoS attacks.

Drive-by downloads:

Drive by downloads install malware when users visit a compromised or harmful website. They don’t believe unsuspecting users taking action, like clicking malicious email attachments or links, to infect them.

Exploits and exploit kits:

An exploit may be a piece of malicious code which will compromise a security vulnerability. Many are developed by the safety services. As an example, in 2017 the WannaCry ransomware spread using an exploit referred to as EternalBlue. This exploit was developed and stolen by the US National Security Agency.

Exploit kits are collections of multiple exploits. Available for rent on the dark web, they allow unprofessional criminals to automate attacks on known weak networks.

MITM attacks:

An MITM (man-in-the-middle) attack occurs when a criminal hacker inserts themselves between a tool and a server to intercept communications which will then be read and/or altered.

MITM attacks often occur when a user logs into an insecure public Wi-Fi network. Attackers can insert themselves between a visitor’s device and therefore the network. The user will then without knowing pass information through the attacker.

Social engineering:

Social engineering is employed to deceive and manipulate victims so as to get information or gain access to their computer. It does this by tricking users into clicking malicious links or by deceiving them to physically access a computer.

Phishing attacks:

Phishing may be a method of social engineering wont to trick people into divulging sensitive or tip, often via email. Not always easy to differentiate from genuine messages, these scams can inflict enormous damage on organizations.

How To Prevent Cyber Attacks

Update your software and operating system: This means you are using the latest security patches.

Use strong passwords: Make sure your passwords are not easily guessable.

Do not open email attachments from unknown senders: they could be infected with malware.

Don’t click links in emails from unknown senders or unknown websites: This is a common way of spreading malware.

Avoid using unprotected WiFi networks in public places: Unprotected networks leave you vulnerable to man-in the middle attacks.
