By security we mean safety. And cyber security is security for the digital world. The process that ensures the security of our important information in the digital world we use such as mobile, computer is cyber security. None of us are safe in this world of current technology because we may know how to use digital devices, but we don’t know how to keep ourselves safe in this digital world. And so, it is very important to keep ourselves safe to avoid attacks from hackers in the virtual world.
What is Cyber Security
Cyber ​​security is often abbreviated as “cybersec”. Cyber ​​security is the type of security that should be given to digital devices to protect them from threats such as computer system, network, device data theft, damage or anyone else can’t access it.
Through this, we can keep our own information on digital devices safe and confidential.
Why Cyber ​​Security is Needed
Cyber ​​security is a very important issue in today’s digital age especially when we know that none of us is safe in the virtual world so cyber security is very important for us to eliminate this security concern.
Data Protection: Cyber ​​security helps protect our sensitive data from unauthorized access, theft, or alteration. And it contains our personal information and financial information, these are very important and sensitive information. Cyber ​​security helps us keep that information safe.
Maintaining privacy: We have many types of personal information online that is hidden from the online world through virtual security.
Business Continuity: Cyber-attacks can damage business by disrupting business continuity. And so cyber security can protect our business from all these pitfalls.
Protection of Digital Assets: Various types of research information companies keep on their website which is very important and also various types of software, and courses such as digital assets are protected through cyber security.
National security: A cyber-attack is a threat to the security of a country because the government has various types of sensitive information on its servers and also uploads various information related to infrastructure defence to its own servers. Cyber ​​security is very important and important for security.
Financial institutions: Any financial institution is a prime target for cybercriminals. Hacking servers and stealing huge amounts of money is a very common phenomenon in the world of cybercrime.
Health Organizations: Due to the large amount of data of the general public and the huge demand for it in the black market, health organizations are also at a great cyber security risk.
Prevention of Ransomware and Blackmail: Cybercriminals carry out ransomware attacks on organizations or individuals to encrypt their data and then the hackers demand a ransom of varying amounts to release that data. Hence cyber security helps to reduce such chances.
Global Connectivity: The world is digitally interconnected making cyber-attacks a concern for the entire world. Cyber ​​security can protect you from cyber-attacks to some extent.
So, it can be said that cyber security is very necessary and very useful in this digitally connected world of ours which helps to protect us from the attacks that arise from the virtual world.
Types of Cyber ​​Attacks
However, most cyber-attacks involve taking control of various websites or hacking into central servers to steal information. But nowadays there has been quite a change in the type of cyber-attack. Cybercriminals have also made several changes in their attack patterns.
Cyber-attacks can be carried out in various ways to harm an individual or organization. It may be, for business purposes, to attack the opponent or to destroy his establishment. However, we will now learn about some such aspects of cyber-attacks.
DDoS Attacks
DDoS is one of the most common forms of cyber-attack nowadays. Denial of Service is a type of attack where hackers send a large number of requests to the server. After sending a large number of requests, the server goes down or crashes. A denial-of-service attack is executed by a single device.
On the other hand, hackers use multiple compromised machines for DDoS attacks. uses and sends requests to that server. And as a result, it becomes impossible for the common user or anyone else to access that website. Basically, such a method is adopted to attack the business counterparty. By doing this, the opponent’s website is brought down.
Malware Attack
Malware attacks are the most common form of cyber-attack on digital devices. In this method, a part of Malware or Malicious Software is entered into a person’s device by hackers in various ways. As a means of this, most hackers inject viruses into computers through phishing email attacks and email attachments.
When malware is installed on a person’s computer, the other party can steal or track their sensitive information without their permission. In this case, the hacker on the other end steals many of his sensitive data such as his social media account username and password, credit card details, and other important account information.
Ransomware Attacks
Ransomware Attacks are one of the most significant cyber-attacks nowadays. Basically, this type of attack is carried out using Malicious Software. In this method, all the files on a user’s computer are encrypted. A certain amount of money is demanded as ransom to get the decryption key. In most cases, victims of such attacks are ransomed in Bitcoin.
Social Engineering Attacks
In this type of cyber-attack, the user may unknowingly hand over his personal information to the hackers. Social engineering attacks have been conducted for a long time. In this way, a hacker can ask to log in to their account to get a service. In this case, it can be a Facebook or Google account. If you mindlessly click on a link while taking a service and give your Facebook account username and password, then you may be a victim of hacking.
Sometimes hackers can create web pages similar to Facebook or Google’s login interface and ask you to log in. In this case, you must look up the domain name of the original website from the address bar of the browser; So that you don’t enter your Facebook or any other account password on the wrong website.
How to prevent Cyber-Attacks?
Secure all hardware
The importance of hardware security to cyber security is often overlooked. But it’s an easy way to increase the security of your network and devices. Therefore, you make sure that you have a strong firewall system and antivirus solution. And it’s crucial to create strong passwords for your various accounts and store them securely.
Keep device software updated
A common threat to almost every individual being a victim of a cyber-attack is the vulnerability of the software used. Hackers take advantage of such flaws to gain access to a device and gain confidential information. And so, it is important to update any of the software you are using as soon as it gets updated. This way you can get the latest security fixes.
If a security flaw is detected in the software, its developers update the app to fix the flaw. Before updating an app, you can also check its latest update. Update your app by checking what has been changed or added in the latest update. If you see a security update, update it soon.
Use Two Factor Authentication or 2FA
Two-factor authentication is a powerful authentication system. Another name for it is two-step verification. If this verification system is enabled in any one account, then a two-factor authentication code will be required in addition to the username and password to login to it. And this authentication adds extra security in terms of security.
If you are aware of the potential risks and types of cyber-attacks, you will be able to prevent potential cyber-attacks. In this case, you can prepare yourself better. Therefore, for cyber security, you need to always be updated and aware of the security risks.
