Definition of Cyber Security: 

Cyber security can be defined as a set of technologies, processes, and practices designed to protect networks and devices, software, programs and data against attacks, vulnerabilities, damage or unauthorized access. Cyber security is also known as IT (Information technology) security.

or

In simple words, Cyber security is the practice of protecting servers, computers, IT and network devices, electronic systems, and data from threats and malicious attacks.

Cyber Security is also known as information technology security or electronic information security. The Cyber Security term is frequently applied in a variety of platforms, from business to mobile computing, and can be segregated into some common categories.

Why  Cyber Security is Importance?

The Importance Of Cyber Security:

  • Cybersecurity is important because the military, government, business, financial and medical institutions or organizations create, collect, process and store a large chunk of data on computers and other devices.

  • An important part of that data may be secured and confidential information, whether financial data, personal information, intellectual property, or other data for which unauthorized access or exposure would result in negative consequences.
  • Nowadays, Organizations transfer confidential data over conventional IT networks and other devices in the course of their business, and cybersecurity describes the measure dedicated to protecting that information and the systems used to process or store it.
  • As the volume and evolution of cyber threats creates new challenges to companies and organizations, especially those that have the task of protecting information related to national security, financial records, health or must take preventive measures to protect their business information and confidentiality of data.

Types Of Cyber Security:

Network security: It is the practice of protecting a computer network from cyber threats and vulnerabilities, whether selective attackers or opportunistic malware.

Information security: It protects the integrity and privacy of data, both in the stage of storage and in transmission.

Application security: It focuses on ensuring software and devices free of vulnerability and threats. A compromised application could provide access to data that is designed to protect. Effective cyber security begins at the initial design stage, long before a program or device is implemented.

Operational security: It includes the processes and decisions to manage and protect data assets. The permissions that users have when accessing a network and the procedures that determine how and where data can be stored or shared are included in this framework.

Disaster recovery and business continuity: It defines how an organization is ready to respond to a cybersecurity incident or any other event that causes loss of operations or data.

Disaster recovery policies dictate how the organization has taken standard measures to restores its operations and information to return to the same operational capacity as before the event.

Business continuity is the plan that the organization uses when trying to operate without certain resources.

End-user or End Point Security: The most important one! education of End-user addresses the most unpredictable cybersecurity factor: people. Anyone can accidentally introduce a virus into a secure system if they do not follow good security practices. Get users educated to remove suspicious email attachments, not plug in unidentified USB devices, and several other important cyber awareness are vital to the security of any organization

Challenges Of Cyber Security:

  • One of the most difficult challenge in cyber security is the ever-evolving nature of security vulnerabilities and risks poses by the intruders.
  • Conventionally, the government and organizations have focused most of their cybersecurity resources on security aspects to protect only the most critical infrastructure or components of the system and defend against known threats or enemies. In today’s context, this approach is insufficient, as threats move forward and change faster than organizations can keep up.

  • As a result, advisory organizations promote more proactive and adaptive approaches to cybersecurity. Similarly, the National Institute of Standards and Technology (NIST) issued guidelines in its risk assessment framework that recommend a shift towards continuous monitoring and real-time assessments, a data-centric approach to security rather than the traditional perimeter-based model.
  • For effective cybersecurity, an organization needs to coordinate its efforts throughout its information system. The elements of cyber security cover all of the following:
      • Network security
      • Application security
      • Database and infrastructure security
      • Cloud security
      • Mobile security
      • Endpoint security
      • Data security
      • Identity management
      • Disaster recovery/business continuity planning
      • End-user education

Cyber Security Management:

The National Cyber ​​Security Alliance (NCSA), through SafeOnline.org, recommends a top-down approach to cybersecurity in which corporate management leads the task of prioritizing cybersecurity management in all business practices.

The NCSA reports says that companies must be prepared to “respond to the inevitable cyber incident, restore normal operations and ensure that the company’s assets and the company’s reputation are protected.”

The NCSA guidelines for conducting cyber risk assessments focus on three key areas:

  1. Identifying the “crown jewels” of your organization, or your most valuable IT asset that requires protection.
  2. Identifying the threats and risks that informational data may face.
  3. Outlining the damage that your organization would incur if such data is lost or exposed by mistake.

Types of cyber security threats:

The threats posses by cybersecurity are threefold:

1. Cybercrime includes individual actors or groups that point to systems to obtain financial gain or cause disruptions.

2. The cyber attack often involves the collection of politically motivated information.

3. Cyberterrorism is intended to undermine electronic systems to cause panic or fear.

So how do malicious agents or actors gain control of IT systems? These are some common methods used to threaten cybersecurity:

Malware: Malware means malicious software. One of the most common cyber threats, malware, is software that a cybercriminal or hacker has created to interrupt or damage a legitimate user’s computer. Often propagated through an unsolicited email attachment or a legitimate-looking download, cybercriminals can use malware to make money or in politically motivated cyber attacks.

There are several different types of malware, which includes:

  • Virus: A self-replicating program or code that is attached to clean files and spreads through a computer system and network systems, infecting files with malicious code.
  • Trojans: A type of malware that poses itself as legitimate software. Cyber ​​criminals trick users into loading Trojans on their computer where they cause damage or collect data.
  • Ransomware: A malware that blocks access to user’s files and data, with the threat of deleting it unless a ransom or demand is paid.

  •  Adware: An advertising software that can be used to spread malware.
  • Spyware: A program that secretly steals information what a user does, so that cybercriminals can make use of this information. For e.g., spyware could capture credit card details.
  • Botnets: Computer networks gets infected with malware that cybercriminals use to perform online tasks without the user’s permission.
  • Man attack in the middle: A man attack in the middle is a type of cyber threat in which a cybercriminal intercepts communication between two individuals to steal data. For e.g, in an unsecured WiFi network, an intruder could intercept the data transmitted from the victim’s device and the network.
    • Identity fraud: Impersonation occurs when cyber criminals attack victims with emails that appear to come from a legitimate company that requests confidential information. Phishing attacks are often used to trick people into delivering credit card data and other personal information.
    • Denial of Service Attack: A denial of service attack is when cybercriminals prevent a computer system from satisfying legitimate requests by overwhelming networks and servers with traffic. This makes the system unusable, preventing an organization from performing vital functions.
    • SQL injection: An SQL injection (structured language query) is a type of cyber attack used to take control and steal data from a database. Cybercriminals exploit vulnerabilities in data-based applications to insert malicious code into a database through a malicious SQL statement. This gives them access to the confidential information contained in the database.

    It would not be wrong if we say today’s generation lives on the internet. So your private data on social networking sites, online shopping, chatting apps, and in this digital world, how much secure? let us know.
