What is Cyber Security

In this present world where almost everyone is connected via internet, most of us, at least once, have heard the term ‘Cyber Security’. But what is actually? Is it just securing ourselves, our precious devices and data from the attacks of the web world? Here we will explore the vast areas of Cyber Security.

According to Kaspersky, one the worlds leading security software makers, it is a practice of defending the computer systems, electronic items, mobile devices, network and our data from a malicious attack from anywhere. It can be applied for various contexts like business computing, mobile banking applications etc.

As the number of users and devices increases, the rate of cyber threats continues to evolve at a rapid pace. According to the studies by various security firms, data breaches up to September 2019 have exposed almost 2.9 billion records, which is double the number of breaches than the previous year.

Most of the cyber-attacks targets the internal network of a business, organisation or government sectors. Securing the network from intruders or malware is very important. Internal network is the backbone of every organisation. For securing the network from intrusion, companies adopt several methods like internet security software’s and also dedicated hardware-based security products like firewall devices are available now for corporate intrusion prevention.

Application security is yet another major area. The cost of most software are many times higher than the device which we are using it. Most people can’t afford the price for that software. Even though there are lots of free software available from trusted sources, people tend to go for cracked versions of the paid software. Most cracked software comes with a bundle of adware or trojans, which we will discuss later.

The types of cyber threats can be mainly classified into three. Cybercrimes, Cyber-attack and Cyberterrorism. When Cybercrime is mainly a targeted attack for financial gain or to cause disruption, there is a specific agenda behind cyber attack which is gathering the information. Cyber terrorism is intended to cause panic, fear or to collapse the economy of a country or a community.

The most common method used to gain control of a computer system or network is called a malware. Malware is a malicious software, used by cyber criminals to hack into the system. Malware usually spread through emails or USB drives. The different types of malwares affect our system are Viruses, Trojans, Spyware, Ransomware, Adware and Botnets.

There are different methods a user can adopt to fight against these attacks.

  • Use of genuine software and operating system, which gives you proper updates and security patches time to time.
  • Use of security software like Antivirus, Internet security etc
  • Use of Strong and Complicated Passwords for your local accounts, mails and banking applications and change it in regular intervals.
  • Do not open emails from unknown senders, do not click on suspicious attachments. Most emails stating you have won a lottery or mentioning you are the lucky winner is an absolute hoax. Don’t fall into that trap.
  • Do not share your passwords with anyone also do not make your phone number public or share the OTP’s with anyone.
  • Avoid using unsecured public free Wi-Fi. Connecting to most public Wi-Fi can cause immediate data loss.

Even doing all the above steps and precautions you are prone to attacks. Attackers find new and advanced ways to loot you always. Be aware of the things happening in the cyberworld. Don’t fall into trap.
