What is Cyber Security?
Cyber security is the practice of protecting systems, networks, and programs from digital attacks. These cyber-attacks are usually geared towards accessing, changing, or destroying sensitive information; extorting cash from users; or interrupting traditional business processes. Implementing effective cyber security measures is especially difficult nowadays as a result of there are a lot of devices than folks, and attackers have become a lot more innovative.
The term applies in a variety of contexts, from business to mobile computing, and can be divided into a few common categories.

Network security is that the follow of securing a network from intruders, whether or not targeted attackers or opportunist malware.

Application security focuses on keeping software system and devices freed from threats. A compromised application may offer access to the info it’s designed to guard. Successful security begins within the style stage, well before a program or device is deployed.

Information security protects the integrity and privacy of data, both in storage and in transit.

Operational security includes the processes and selections for handling and protective information assets. The permissions users have once accessing a network and also the procedures that verify however and wherever information is also hold on or shared all make up this umbrella.

Disaster recovery and business continuity outline how a corporation responds to a cyber-security incident or the other event that causes the loss of operations or information. Disaster recovery policies dictate how the organization restores its operations and data to come back to a similar operative capability as before the event. Business continuity is the plan the organization falls back on while trying to operate without certain resources. Business continuity is the plan the organization falls back on while trying to operate without certain resources.

End-user education addresses the foremost unpredictable cyber-security factor: Anyone will accidentally introduce an outbreak to an otherwise secure system by failing to follow sensible security practices. Teaching users to delete suspicious email attachments, not plug unidentified USB drives, and numerous different necessary lessons is important for the protection of any organization.

Types of cyber threats.
Malware
Malware means malicious software. One of the most common cyber threats, malware is software that a cyber criminal 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
cyber criminals to make money or in politically motivated cyber-attacks.

There are a number of different types of malware, including:

Virus: A self-replicating program that attaches itself to clean files and spreads throughout a computer system, infecting files with malicious code.

Trojans: A type of malware that is disguised as legitimate software. Cyber criminals trick users into uploading Trojans onto their computers where they cause damage or collect data.

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

Ransomware: Malware that locks down a user’s files and data, with the threat of erasing it unless a ransom is paid.

Adware: Advertising software that can be used to spread malware.

Botnets: Networks of malware-infected computers which cyber criminals use to perform tasks online without the user’s permission.

SQL injection
An SQL (structured language query) injection is a type of cyber-attack used to take control of and steal data from a database. Cyber criminals exploit vulnerabilities in data-driven applications to insert malicious code into a database via a malicious SQL statement. This gives them access to the sensitive information contained in the database.

Phishing
Phishing is when cyber criminals 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 where a cyber criminal intercepts communication between two individuals in order to steal data. For example, on an unsecured Wi-Fi network, an attacker could intercept data being passed from the victim’s device and the network.

Denial-of-service attack
A denial-of-service attack is where cyber criminals 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.

Zero-day attack
Zero-day attacks are becoming more and more common. Essentially, these attacks occur between a network vulnerability announcement and a patch
solution. In the name of transparency and security, most companies will announce that they found a problem with their network safety, but some criminals will take this opportunity to unleash attacks before the company can come up with a security patch.

Importance of Cyber Security

Cyber security is vital because it encompasses everything that relates to protecting our data from cyber attackers who wish to steal this data and
use it to cause damage. this may be sensitive data, governmental and trade data, personal data, in personal identifiable information (PII), protected health information (PHI). Having advanced cyber defense programs and mechanisms in situ to shield this data is crucial and in everyone’s interest. Everybody in society depends on vital infrastructures like hospitals and different tending establishments, monetary service programs,
and power plants. we want these to stay our society running. At a personal level, cyber security attacks will cause fraud and extortion makes an attempt, which might do serious injury thereto individual’s life.
We all must rely on security of our data and private data. For instance, when logging into an application or when filling in more sensitive data in digital healthcare systems. If these systems, networks, and infrastructures haven’t got the proper protection in situ, our data may fall into wrong hands. During this sense, we’re talking regarding protection within the kind of technology and policies. An equivalent goes for organizations and businesses, governments, the military and different socially vital organizations. They store monumental amounts of data in data warehouses, on computers, and different devices. a lot of of this knowledge includes sensitive data.
