What is cyber security threat, importance, and uses of cyber security

What is cyber security?

Cybersecurity refers to the process of protecting critical systems and sensitive data against digital attacks. Cybersecurity measures, also known as information technology (IT) security, are designed to protect networked systems and applications against attacks that originate within or outside of a firm.

A data breach will cost an average of USD 3.86 million globally in 2020, and USD 8.64 million in the United States. These expenses include the costs of discovering and responding to the breach, as well as the costs of downtime and lost revenue, as well as the long-term reputational damage to a company’s brand. Customers’ personally identifiable information (PII), such as names, addresses, national identity numbers (e.g., Social Security numbers in the United States, fiscal codes in Italy), and credit card information, are targeted by cybercriminals and sold on underground digital marketplaces. Customer trust is routinely undermined as a result of PII breaches, which may result in regulatory penalties and even legal action.

Prices may rise due to the complexity of security systems, which is worsened by various technologies and a lack of in-house experience. Companies that implement a comprehensive cybersecurity strategy based. Best practices and automation, such as advanced analytics, artificial intelligence (AI), and machine learning. May be able to successfully combat cyber threats and limit the duration and severity of breaches when they occur.

Importance of cyber security:

The importance of cyber security is that companies no longer have to worry about unauthorized persons accessing their network or data because of cyber security. It aids them in protecting both their clients and their employees. Even if security does not prevent an attack or breach, it does shorten the recovery time.

What are the 5 types of cyber security?

Critical infrastructure cyber security:

Critical infrastructure businesses are more vulnerable to assault than others because SCADA (supervisory control and data acquisition) systems are often based on obsolete software.

The NIS Regulations apply to operators of essential services in the UK’s energy, transportation, health, and water sectors, as well as digital service providers (Network and Information Systems Regulations 2018).

Among other things, the Regulations compel enterprises to take appropriate technological and organizational actions to mitigate their security risks.

Application security:

Application security is concerned with addressing vulnerabilities that arise from unsafe development procedures in the design, coding, and publication of software or a website.

Cloud security:

The security of data, apps, and infrastructure in the cloud is the focus of cloud security.

IoT (Internet of Things) security:

The IoT security refers to the safeguarding of smart devices and networks linked to the internet of things. IoT devices that connect to the Internet without human intervention include smart fire alarms, lights, thermostats, and other appliances.

Network security:

Network security includes addressing vulnerabilities in your operating systems and network architecture. Such as servers and hosts, firewalls and wireless access points, and network protocols.

Types of cyber threats:

• The following are examples of common cyber threats:
• Malware includes ransomware, botnet software, RATs (remote access Trojans), rootkits and bootkits, spyware, Trojans, viruses, and worms.
• Remote access using backdoors
• Formjacking is the practice of inserting harmful code into online forms.
• The act of installing illegal bitcoin mining software on a computer is known as cryptojacking.
• DDoS attacks (distributed denial-of-service) flood servers, systems, and networks with traffic in an attempt to knock them down.
• DNS poisoning attacks, in which the DNS is hacked and traffic is routed to malicious websites.

What are the advantages and disadvantages of Cyber Security?

Advantages of Cyber Security:

• It protects individuals and organizations from the theft of personal and sensitive data.
• The main advantage of implementing these superb cyber-security measures is that networks may be safeguarded against multiple phony nodes attempting to gain unauthorized access to the network.
• The most important aspect is that it increases the system’s cyber-security.
• It decreases the possibility of computers being hacked, as well as system freezes and malfunctions.
• It enhances the firm’s overall security processes by utilizing a better information structure, resulting in smooth company management operations.
• It protects sensitive information that may damage users’ sentiments if released, giving consumers and companies much-needed privacy.
• It is beneficial to one’s mental health since it provides a sense of security.
• Stakeholder support for the company’s stringent cybersecurity processes has grown.
• If effective cyber security mechanisms were built, the stolen data might be easily retrieved.
• The firm’s credentials are more reliable with a solid security system in place.

Disadvantages of cyber security:

• Cyber security may be costly due to the need for highly qualified personnel.
• The most recent security patches must be regularly updated with the most recent security definitions, which is difficult to keep track of.
• To keep the system safe, a firewall must be correctly configured, which is a difficult task. Because multiple security measures must be applied successfully, legitimate users may be shut out of the system if they are not.
• Identity management may be another issue for the organization. Since it is probable that the company lacks defined access controls, enabling anybody to use the system.
• The continually changing nature of security threats is the most difficult part of cyber security. As a result, the organization may be unable to take any proactive strategies for safeguarding its data from different cyber-attacks.
• While remote access is an important component of the firm, it may also be a security weakness because an attacker can gain unauthorized access over this network.
• AI development is a challenge for cybersecurity since robots are being designed to avoid cyber-attacks.
