Cybersecurity acts a shelter on the internet-connected devices such as hardware, software from cyber attacks. It is also used by individuals and organizations to protect themselves against unauthorized access to data centres or exploitations of systems and technologies.
It also ensures the integrity and confidentiality of data. Thus, it provides risk management methods, pieces of training, technologies to protect networks from attack.
We enforce cybersecurity to provide better security to computers, networks, servers and data stored on these devices from attackers with venomous intent. Cyber attacks can be mild or destructive. Attackers can access, delete user’s sensitive data or extort money. If we want to make cybersecurity crucial, govt. and financial institutions may hold confidential information on an individual.
Cybersecurity is a dynamic field. With the development of technologies, attackers also come with new types of attack strategies. Problems mainly arise in small organizations as compared to big organizations because they are concern with security rifts. Small companies are often targets of virus etc.
Why CyberSecurity is Important?
In today’s world, cybersecurity is a need for all. It becomes a part of the computer’s life. It is important because the government, financial, corporate, and medical organizations stored a huge amount of data on their Computers. The data they are storing can be hypersensitive. Whether it is related to financial data, personal data or other types of data for which unauthorized exposure could have negative effects on an individual or organization.
For example for doing business, organizations have to send important data to other devices across the network. Cybersecurity aims to protect the transmitting information. As the graph of cyber attacks grows, service providers need to take steps to protect sensitive and personal information.
Types of CyberSecurity
- Application Security
Its main goal is to protect the software and hardware from viruses. An infected application can provide access to the data. Security starts in the designing stage before the application has been set up for use. For example antivirus software, firewalls and encryption.
- Network Security
It helps to protect the network from interlopers. For example network security is implementing the two network authentication, strong passwords etc.
- Information Security
It helps to protect the probity and data privacy. It protects both physical and digital data from unauthorized access.
- Cloud Security
Software that safeguards and supervise our data on the cloud which helps in eliminating the risks.
- End-user Education
People often make mistakes. Everyone makes mistakes in this world. However, without doing mistakes no one can even learn anything. But here everyone has to be more careful otherwise the consequences will be disastrous. For example, we have to teach the users to delete the incredulous emails. Do not open any USB without scanning it. Do not click on unknown links.
- Security of Infrastructure
It contains physical systems like power grid and water distillation systems.
Types of CyberSecurity Threats/attacks
Its main purpose is to get unauthorized access or to destruct the computer. For example, such software are computer viruses, spyware, and Trojan horses etc.
It is a type of venomous software. The main purpose is to extort money by blocking access to system files through encryption until a ransom is paid. But paying ransom money does not provide you guarantee that your files will be recovered.
- Social Engineering
A way that the attacker uses to trick you so that you can reveal confidential information. They can gain access to your protected data. It combines with any threats like click on unknown links, download virus etc.
In Phishing an attacker sends fake emails that resemble emails from esteemed sources. But their aim is to steal very important data such as debit card numbers, credit card numbers and login information etc.
Three bases of Cyber Security
Each employee in an organisation must be aware of cyberattacks. Cybersecurity department must be up to date with the latest risk, viruses and its solutions as well. They should also be aware of cybersecurity principles.
Companies must have a structured process for how they deal with cyber attacks. As cyber-attacks are fastly evolving, there should a clear and well-defined process. Firstly, how you can identify and respond to attacks. Secondly, protect the systems. And finally, successfully recover from attacks.
It is the need of every organisation and individuals. However, it provides security tools to protect themselves from cyber-attacks. The devices which need protection are computer, mobile devices, networking devices like router, modems. At present these tools and utilities provide protection are firewalls, DNS filtering, antivirus software etc.
The Scale of Cyber Security Threats
The universal cyber threat continues to grow at a very fast speed. The number of data breaches cases increases every year.
Medical organisations and retailers face more violations. These departments are moving towards to cyber cell because attackers collect medical and financial data.
As the rate of cyberattacks continues to rise, the International Data Corporation assumes the spending on cybersecurity will reach more than $ 130 billion by 2022 worldwide. Government worldwide has acknowledged the rising cyber-attacks and instructs to help companies by adopting good cybersecurity practices.
Also, you can see in the United States, the NIST has created a cybersecurity framework to battle with the rising of venomous code and try to detect it in the early stage. The framework also recommends regular observing electronic resources.
To protect yourself from these cyber threats you, it’s vital to know different types of cybersecurity threats:
- Terrorism– This is designed to break electronic systems and inculcate panic in victims.
- Attacks– This is committed to stealing out confidential information or maybe for political reasons.
- Crime- This is done by an individual or a group with the purpose of financial gain or wants to create chaos by targeting your system.
The Advantages of Cyber Security
- It protects the end-user.
- Helps in improving recovery time after the violation.
- Prevents access from unauthorized users.
- Provides protection for networks and data.
- Protects the business against all types of threats like malware,
- ransomware, social engineering etc.
How to protect yourself from Cyber Attacks?
- Never use unprotected Wi-Fi in public places: When it connects it may steal your very important data.
- Do not click on unknown links in emails from anonymous sender: By this way, they can spread the malware.
- Never open mail attachments from strange sender: Because these emails can be infected with malware.
- Use Vigorous passwords: Always use strong passwords which cannot be guessed easily.
- Using Antivirus Programs: By installing any antivirus programs like bit defender security, quick heal, Kaspersky etc. will secure your computer by detecting and removing threats.
- Keep on update your operating system: Protect the PC by updating your system and software.
Careers in Cyber Security
Cyber attacks are continuously rising in a speedy way. With the development of new technology, attackers also come with new tactics and tricks. For this, a candidate needs good skills and need to adopt good cybersecurity practices to combat cyber attackers.
Some IT specialists are required to do security jobs as:
- Security architect: In this, the individual is responsible for providing security to the company’s computer system. He/she must think and acts as a hacker so that they can understand all the moves and tricks the hacker will use to gain unauthorized access to computer systems.
- Security engineer: In this the individual performs all the activities like planning, implementing, managing, monitoring security measures for the safeguard of the company’s data and networks. He also responds to all the networks violation and troubleshoots network and security problems.
- Security analyst: The job duties of security analyst are to install software like firewalls to protect the computer networks. He also plans and finds some important measures to safeguard the company’s networks and systems. As the number of cyberattacks increases, their duties also increase.
- Ethical Hacker: It is also called a white-hat hacker and the role of the ethical hacker is to find and exploit weakness and problems in several systems. Just like a black hat hacker. They enter into systems ethically and legally.
- CISO (Chief Information Security Officer): He/she is the chief level executive in an organization. He is responsible for establishing the company’s strategy, takes care of its vision. It also takes care of the company’s assets and technologies are completely appropriate.
- Incident Responder: The duties of incident responder are to provide an instant response to any security threats, invasion as they enter in company’s network. It ensures systematic changeover during hardware or software fixes and patches.
