There are five types of cyber security: power grid, water purification, traffic lights, and retail complexes. Cyber security professionals protect these systems against damage or failure that could result from cyber attacks.
The power grid is the network of generators, transmission lines, and distribution networks that provide electricity to our homes and businesses. The cyber security professional protects this system by monitoring it for signs of intrusion and by implementing appropriate countermeasures when necessary.
The water supply infrastructure is also known as hydropower production facilities, which include dams, reservoirs, treatment plants, and distribution networks. The cyber security professional protects this system by identifying vulnerabilities in the design and maintenance process and by preventing unauthorized access to water supply systems.
The traffic light control system can be found at most intersections across the country. This system is responsible for regulating the flow of traffic by coordinating the activation of red, yellow, and green lights. The cyber security professional protects this system by ensuring that it is secure from malware and malicious intrusions.
Retail complex-related security issues involve payment processing systems, online stores, and other technologies used by retailers to transmit credit card information over the Internet. The cyber security professional protects these systems by evaluating their risk profiles and by implementing appropriate countermeasures when necessary.
What Are the Various Types of Cybersecurity?
However, there are three major forms of IT security: network security, end-point security, and Internet security (the cybersecurity subcategory). Other forms of IT security may typically be classified as falling under one of these three categories. For example, file security would be considered a form of end-point security.
Network security is the practice of protecting data networks against unauthorized access, modification, or destruction. Network security involves preventing attacks on computers connected to the network, monitoring activities on the network for signs of intrusion, and responding to attacks if they occur.
End-point security is the practice of protecting personal computers and other devices that connect to information technology (IT) systems, such as smartphones, tablets, and USB drives. End-point security includes techniques such as password protection and encryption. End-point security does not involve connecting all devices to the network, so it can be practiced independently of network security.
Internet security is the practice of protecting data while it's transferred over the Internet. The two main methods used to protect data during transfer are encryption and authentication. Encryption transforms data into an unintelligible form that cannot be read by anyone other than those who know the decryption key. Authentication ensures that data has come from where it is said to have come from. It does this by using passwords or cryptographic keys.
Cyber security experts should be well-versed in the following sorts of cyber security threats:
Closed circuit television systems (CCTV), Automated Access Control Systems (AACS), and Intrusion Detection Systems are the three basic types of electronic security systems (ID).
In a closed-circuit television system, video images are captured by cameras that are connected to a control panel which monitors activity in the protected area. When an intrusion is detected, the control panel sends an alarm signal to security monitoring stations, where it is transmitted by radio or telephone line to a central station. At the station, police officers can view the video image of the crime scene on a computer screen and take appropriate action.
An automated access control system works like a closed-circuit television system, but instead of cameras, infrared (IR) beams are used to detect intruders. The IR sensors are mounted near entry points into buildings or rooms. If someone passes through one of these beams, the system will notify the controller, which in turn will open one of several doors or gates to allow them entry. The system may also include a microphone to detect voices or other noise beyond normal levels. In this way, people can be allowed entry after hours when the building is empty but security is still present.
Intrusion detection systems work by monitoring a facility's physical environment for changes that might indicate an intruder.
There are three sorts of security system packages available on the market today: home automation, security equipment, and environmental monitoring. Home automation includes such products as lighting control systems, window coverings, alarm systems, and air-conditioning controllers. These are all integrated together using a central controller. They can work independently or in conjunction with one another.
Security equipment consists of everything from door locks to video surveillance equipment. This type of system is used to protect homes, businesses, and other structures. Security systems come in two main varieties: internal security systems and external security systems.
An internal security system uses sensors and control panels located inside the protected structure to activate alarms when intruders are detected. These systems are convenient because they don't require any wiring outside of the building itself. The only maintenance needed is a battery replacement every few years.
An external security system has sensors that monitor for signs of intrusion outside of the protected structure. When someone tries to break into a house, for example, static-charged cables will be exposed on the ground. Electronic sensors use electricity to detect movement and make an audible alert if someone trips the switch. Video cameras capture images of anyone trying to break into your property, which can help police identify suspects later.
Cyber attack protection is critical for all businesses and organizations. The following are some instances of common cyber assaults and data breaches: Identity theft, fraud, and extortion are all forms of extortion. Malware, phishing, spamming, spoofing, spyware, trojans, and viruses are some of the most frequent forms of malware. Laptops and mobile devices that have been stolen are examples of stolen gear. A disgruntled employee or unauthorized user is an example of an outside party stealing information.
Organizations can protect themselves from cyber attacks by using strong passwords, not sharing account credentials, installing anti-virus software, and keeping systems up to date. Also, communicating with customers and employees via secure channels (such as encrypted emails) can help prevent leaks of personal information. Finally, training employees on cyber security practices can go a long way toward preventing incidents such as this one.
Cyber attacks can have a huge impact on business operations. If your company has been target of a cyber attack, it may be necessary to shut down certain functions or even file for bankruptcy. It's important to identify threats early on and take measures to prevent future attacks.
