What is Cyber Security?

Cyber security, also called computer security or information technology is the process of protecting the system and networks from the disclosure of information, damage or theft occurring to the hardware and software of the system.

As everything is digitalized nowadays, digital attacks are happening to capture sensitive information or data in the system. To eradicate this problem, cyber security is implemented. Various forms of cyber threats are occurring in confidential data. Hence technologies like artificial intelligence and machine learning save data. This security system identifies whether this threat occurred inside or outside the system.

Types of Threat

The various types of the threat occurring in computer technology are listed below:

Malware

Malware is known as malicious software such as viruses, Trojans, worms and spyware, which cause unwanted access or damage the computer system. As malware attacks are increasing widely, techniques like antivirus tools and the scanning process of malicious file attachments should be done.

Ransom ware

Ransomware is the process of locking the files or data which threatens to erase the data and tries to display the private data in a public manner of sensitive data until a ransom amount is paid to the individual who launched this attack. Recently, ransom attacks are targeting state and local governments to easily breach the organizations to get a ransom to restore the applications and websites.

Phishing

Phishing is a form of social engineering which provides its own PII or sensitive information. The scam is done by sending emails or text messages that appear to legitimate companies that ask for sensitive information like login process data or bank card details.

Insider threats

Inside threats are occurred by the company or organizations employees, contractors or partners who abuse their access permissions is called inside threats. The inside threats cannot be visible to the security system, such as firewalls and intrusion detection systems where it concentrates on an external system.

Denial of Service attack (DOS)

A denial of service attack tries to crash a server, website or network by overloading traffic from multiple coordinated systems. It attacks the network enterprise through the Simple Management Protocol, which is used for switches, routers, printers, modems and servers.

Advanced Persistent threats (APTs)

In advanced persistent threats, a group of intruders infiltrate a system which remains undetected for an extended period. The intruder leaves the network and system intact, so the intruder can easily spy on business activity that steals sensitive data. An example of Advanced Persistent threats is the Solar Wind Breach of the United State Government system.

Man-in-the-middle attacks

A man-in-the-middle attack is similar to eavesdropping, where a cybercriminal intercepts and relays messages between two persons to theft the data. An example is the third party access through an unsecured Wi-Fi network to intercept the data being passed between the guest device and network.

Various domains in Cyber Security

The various domains present in Cyber Security are,

  1. Critical Infrastructure Security-It protects the computer system, networks and multiple assets, including national security, public health and economic safety. The National Institute of Standards and Technology created cyber security to help organizations in this area, and the Department of Homeland Security provided guidance.
  2. Network Security- Network security includes wired and wireless communication systems protecting them from intruders.
  3. Application Security-Applications are protected at the initial stage of the designing process for data handling and user authentication in the cloud.
  4. Cloud Security-The confidential information in the cloud is travelled using encryption in the storage state and processed to support customer privacy, business requirements and regulatory standard of compliance.
  5. Information Security-Data or information is protected using General Data Protection Regulation or GDRP, which secures confidential data from third-party access, theft or exposure.
  6. End-user education-To strengthens the endpoint security, and security awareness is built across the organization. Users can be taught to delete malicious email attachments, avoiding unknown USB devices.
  7. Mobile Security-Mobile security is managing and securing the mobile workforce with application security, container app security and secure mobile application.

Summary

Cyber security plays a vital role in handling and securing data and information. It connects all resources of data from various attacks. Day by day, the data and information are increasing day by day. Thus, the importance of cyber security is rising for protecting data.
