The Internet nowadays is the main source of communication over the globe. Everyone is relying on the internet because it has made our life’s easier and faster. Just like the real world, there are criminals in the virtual world of the internet. So, to prevent them “Cybersecurity” came in action to protect our data and system from cyber-attacks.

Cybersecurity has become a serious issue to discuss nowadays. Peoples are earning through various ways from the internet nowadays, for example, Youtube, Olx, Facebook these all companies are continuously under attack, but because they have invested a lot in cybersecurity they are running safely. Let’s take another example of banks if our bank accounts are hacked, the hacker transfer all the to his account, for which banks are also investing a lot on cybersecurity techniques. If you’re in the United States, you can follow top cybersecurity firms in Pittsburgh, that are best in providing their services that help mitigate this problem.

However, one must be aware of the cyber-attacks. There are various types of attacks, Such as trojans attacks, Social Engineering attacks, Phishing attacks; and ransomware attacks. Let's have a brief look at them:

Trojan Attack

This attack works the same as when trojans attacked Greeks when they tricked them by offering a gift. The attacker will send you an email attachment, with some good words written in your email draft. When you open it, the attacker can gain access to your system and hence security compromise. So, don’t accept any attachment of an email, if it is unknown. 

Social Engineering Attack

In this kind of attack, the “Hacker” will try to convince you to provide your credentials to him. It has been mostly found in bank account cases. The attacker will call you as a banking officer and ask you to provide your bank account number and credentials. Therefore, nowadays banks, send messages that they never ask for passwords. So be aware and never provide your credentials to anyone.

Phishing attack 

This kind of attacker is mostly found in your own office or organization. Due to some reason the employee leaks the organization confidential information or if it is an IT person, he can delete all the system files, which will bring the company’s system down.

Ransomware attack

This is the most recent type of attack. The hacker will hack your system and encrypt the system file. To decrypt the file, a hacker will ask for a ransom amount. Thousands of computers were hacked in 2019, where many of them were server machines. It was found that all those computers which were not updated with the latest patches of security were hacked. So, to prevent an attack like this, always keep your security patches updated. 

Here I would like to suggest that all people must take general awareness training, to prevent such attacks. Schools and colleges also include the extra subject of cybersecurity in their syllabus. For seeking security against cybercrime, one must look following important points:

Never use common passwords or codes

Though it might be problematic for many people to remember intricate passwords and it is quite possible that you stay blank while logging in. But it is safer! Here you can jot down your passwords and keep them secret, it's better to remain safer than to be easily accessible for the hacker. So the advice here is: Use difficult passwords – that no one can guess. For this, you can use different symbols like: @, #, $, % or so on. Or you can add up some numbers, and letters with upper and lower cases.

Encrypt your data

If your data will be encrypted, like your personal information, photos, videos, files or address books, the hacker cant access it. So once a hacker approaches your files, he can’t get access to your files, rather he would encounter somewhat gobbledygook.

Always Keep a back-up

Meanwhile, you should also keep your data on the safer side, as a backup. In case you lose your device or your device gets hacked, you should have your personal and important data be duplicated, using different sources like cloud storage or USB or a memory card. By this, you’d at least be satisfied enough in having your data in back-up.
