In this blog we learn about cyber security what is it and what is cyber security so learn.

what is cyber security

Cyber security is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. We can divide cybersecurity into two parts one is cyber, and the other is security. Cyber refers to the technology that includes systems, networks, programs, and data. And security is concerned with the protection of systems, networks, applications, and information. In some cases, it is also called electronic information security or information technology security.

Types of Cyber Security

Network security is the practice of securing a computer network from intruders, whether targeted attackers or opportunistic malware. 

Application security it includes shielding the product and gadgets from undesirable dangers. This insurance should be possible by continually refreshing the applications to guarantee they are secure from assaults. Effective security starts in the plan stage, composing source code, approval, danger demonstrating, and so on, before a program or gadget is conveyed.

Information or Data Security it involves implementing a strong data storage mechanism to maintain the integrity and privacy of data, both in storage and in transit.

Identity management it deals with the procedure for determining the level of access that each individual has within an organization.

Operational Security It involves processing and making decisions on handling and securing data assets.   

End-user education addresses the most unpredictable cyber-security factor: people. Anyone can accidentally introduce a virus to an otherwise secure system by failing to follow good security practices. Teaching users to delete suspicious email attachments, not plug in unidentified USB drives, and various other important lessons is vital for the security of any organization.

Why is Cyber Security important?

Today we live in an advanced time where all parts of our lives rely upon the organization, PC and other electronic gadgets, and programming applications. All basic framework like the financial framework, medical care, monetary establishments, states, and assembling ventures use gadgets associated with the Web as a center piece of their tasks. A portion of their data, like protected innovation, monetary information, and individual information, can be delicate for unapproved access or openness that could have unfortunate results. This data gives interlopers and danger entertainers to invade them for monetary profit, coercion, political or social intentions, or just defacing.

Digital assault is currently a worldwide worry that hacks the framework, and other security assaults could jeopardize the worldwide economy. Subsequently, it is fundamental to have a great network safety technique to shield delicate data from high-profile security breaks. Besides, as the volume of digital assaults develops, organizations and associations, particularly those that arrangement with data connected with public safety, wellbeing, or monetary records, need to areas of strength for utilize measures and cycles to safeguard their delicate business and individual data.

Types of Cyber Security Threats

The global cyber threat continues to evolve at a rapid pace, with a rising number of data breaches each year. A report by Risk Based Security revealed that a shocking 7.9 billion records have been exposed by data breaches in the first nine months of 2019 alone. This figure is more than double (112%) the number of records exposed in the same period in 2018.

Types of cyber threats

 Malware means malicious software, which is the most common cyber attacking tool. One of the most common cyber threats, malware is software that a cybercriminal or hacker has created to disrupt or damage a legitimate user’s computer. Often spread via an unsolicited email attachment or legitimate-looking download, malware may be used by cybercriminals to make money or in politically motivated cyber-attacks.

Virus It is a malicious piece of code that spreads from one device to another. It can clean files and spreads throughout a computer system, infecting files, stoles information, or damage device.

Spyware A program that secretly records what a user does, so that cybercriminals can make use of this information. For example, spyware could capture credit card details.

Trojans It is a type of malware or code that appears as legitimate software or file to fool us into downloading and running. Its primary purpose is to corrupt or steal data from our device or do other harmful activities on our network.

Ransomware It's a piece of software that encrypts a user's files and data on a device, rendering them unusable or erasing. Then, a monetary ransom is demanded by malicious actors for decryption.

Worms It is a piece of software that spreads copies of itself from device to device without human interaction. It does not require them to attach themselves to any program to steal or damage the data.

 Adware Advertising software which can be used to spread malware.

Botnet Networks of malware infected computers which cybercriminals use to perform tasks online without the user’s permission.

SQL injection

SQL injection is a common attack that occurs when cybercriminals use malicious SQL scripts for backend database manipulation to access sensitive information. Once the attack is successful, the malicious actor can view, change, or delete sensitive company data, user lists, or private customer details stored in the SQL database.

Phishing

Phishing is when cybercriminals target victims with emails that appear to be from a legitimate company asking for sensitive information. Phishing attacks are often used to dupe people into handing over credit card data and other personal information.

Man-in-the-middle attack

A man-in-the-middle attack is a type of cyber threat (a form of eavesdropping attack) in which a cybercriminal intercepts a conversation or data transfer between two individuals. Once the cybercriminal places themselves in the middle of a two-party communication, they seem like genuine participants and can get sensitive information and return different responses. The main objective of this type of attack is to gain access to our business or customer data. For example, a cybercriminal could intercept data passing between the target device and the network on an unprotected Wi-Fi network.

Denial-of-service attack A denial-of-service attack is where cybercriminals prevent a computer system from fulfilling legitimate requests by overwhelming the networks and servers with traffic. This renders the system unusable, preventing an organization from carrying out vital functions.

Latest cyber threats

It is a type of financial Trojan malware identifies by the U.S. in December 2019 that affects the public, government, infrastructure, and business worldwide. It infects computers through phishing emails or existing malware to steal sensitive information such as passwords, banking details, and personal data for fraudulent transactions. The National Cyber Security Centre of the United Kingdom encourages people to make sure their devices are patched, anti-virus is turned on and up to date, and files are backed up to protect sensitive data against this attack.

Emotet malware Emotet is a type of cyber-attack that steals sensitive data and also installs other malware on our device. The Australian Cyber Security Centre warned national organizations about this global cyber threat in 2019.

Romance scams In February 2020, the FBI warned U.S. citizens to be aware of confidence fraud that cybercriminals commit using dating sites, chat rooms and apps. Perpetrators take advantage of people seeking new partners, duping victims into giving away personal data.

Benefits of cybersecurity

The following are the benefits of implementing and maintaining cybersecurity:

Cyberattacks and data breach protection for businesses.

Data and network security are both protected.

Unauthorized user access is avoided.

After a breach, there is a faster recovery time.

End-user and endpoint device protection.

Regulatory adherence.

Continuity of operations.

Developers, partners, consumers, stakeholders, and workers have more faith in the company's reputation and trust.
