Imagine you’re on your laptop and transferring some amount of money to your friend. And hackers are accessing all the passwords which are supposed to be kept confidential. This is then used by the hacker to steal money from your account.

Did this sound a little dramatic? Unfortunately, this happens very much in the reality. And, that is when Cybersecurity comes into the picture. Now, you might be thinking about what is Cybersecurity and Cyber security Importance and how all these are related. Proceed with the reading, and you’ll get to know what is Cybersecurity.

What is Cyber Security? A guide for the beginners

Cyber Security is the practice of protecting systems & information from digital attacks. It protects all categories of data from theft, damage, and cybercrimes. Cybercrimes are the criminal activity that involves a computer, and an internet connection. Generally, organizations have a systematic process and a framework that helps to identify and detect any type of Cyberattacks in well advance. The framework also helps in retrieving the data if the cyber-attack was successful.

Cyber Security Importance

As you now know, what is Cybersecurity, let’s see Cyber Security Importance You might have not realized that most of the activities we perform or enjoy have digital forms. In our daily life, we take the help of the digital medium the n number of times. And, with more such usage, the threat to our data increases.

Various infrastructure in different fields like hospitals, the government sector, businesses, etc contains sensitive information which if lost can cause havoc not only for its customers but also for the owners. Imagine a banking company with no Cyber Security. Cybercriminals if successful can steal from hundreds or thousands of people in a few clicks. Not only big businesses and companies, small business owners, or even individuals can be the target of Cybercrimes. The concept of cyber security is important because it is applicable and to be used by anyone and everyone.

Top Seven Cyber Crimes

Cybercrimes are digital activities that are performed through the internet and are illegal to perform. The goal behind such activities is to steal and misuse the confidential data of the victim without the latter’s permission.
In a world that is now on the verge of becoming digitally dependent for a minute of the activity, there are various types of Cybercrimes, and we’ve mentioned seven types of Cyber Crimes below:

Malware

Malware is the umbrella term that includes viruses, spyware, worms, and trojan horses. These can enter your system through downloads via the internet or your email attachments. Malware is used for:

  • Extracting personal data of individuals
  • Extract data like credit card information for financial gain.
  • Attacking computers first and using them to steal cryptocurrencies.
There are certain signs through which you can identify if your system is infected with Malware. These signs are:
  • Slow Computer processing

  • Browser getting redirected
  • Problem with system shut down or starting with
  • More frequent Ad pop-ups

Phishing

Phishing is sending emails that seem to be authentic and from legitimate sources asking for your data. Hackers generally send such emails that are fraudulent and ask for data like credit card information, usernames, passwords, otps, and more such things. This is the most common type of Cyber Crime as people generally fall for such things.

Phishing can be avoided only by educating individuals. Training on how to detect fraudulent mail and what to do if you come across one should be provided. Also, Network security should be used to determine such malicious mails at an early level.

Man in the Middle (MITM)

Man in the Middle happens during the process of data transfer. The attackers place themselves in the middle of the transfer and then pose as authorized participants. This enables an attacker to send malicious links to both legitimate participants in a way that can’t be identified timely.
This type of Cyber-attack can be prevented by:

  • Not using WIFI that isn’t password protected.
  • Logging out of banking or other important sites when not in use.
  • Avoid public or generic WIFI like coffee shops, and restaurants for confidential transactions.

Denial of Service (DoS)

This type of attack is caused by bombarding the victim’s system with traffic until it gets crashed. DoS can last for a few hours or weeks or months which can cost wastage of time, money, and resources for companies or individuals.
Ways to prevent DoS are:

  • Ensure good network security
  • Pay attention to signs such as crashes, poor connectivity, slow performance, etc.
  • Monitor the network traffic

Ransomware

In Ransomware, the attackers block access to files on the system and demand a huge amount from the victim. Generally, this demand comes with a deadline. If the amount is not paid on time either the data is permanently lost or the amount is increased. However, paying the amount doesn’t guarantee the return of access to all the data.
Here’s what you can do to stay away from Ransomware:

  • Avoid clicking on suspicious links
  • Always try to create a backup of your data
  • Have Anti-virus and firewalls installed
  • Keep updating the essential programs

Social Engineering

Social engineering is the practice of persuading users to provide sensitive & confidential information. During targeting the victim, the criminal tries to trick you to provide bank passwords, or computer access to install the malicious software.  
Thinking about how to stay alert? Here are the ways:

  • Research the source and facts before trusting anyone with information
  • Stay alert of any download on your system
  • Don’t act first and think later

Advanced Persistent Threats (APTs)

An attack in which an unauthorized user gains access to a system or network and stays there for a long time without being discovered is known as an Advanced Persistent Threat. Enterprises are particularly vulnerable to advanced persistent threats because hackers continuously have access to private data.+

Some of the signs of APTs attacks are:

  • A large amount of flow of data
  • Access to network at an unusual time
  • Network with various backdoor Trojans

What is Cyber Security?-What are the types of Cybersecurity?

With so many different ways to attack your system, there are many ways to protect your system from such attacks. Here, we’ve discussed the top six types of Cyber Security:

Application Security

Application security is utilized to safeguard against threats like unauthorized access and modification. It entails developing, incorporating, and testing security controls into applications. The fact that modern apps are regularly accessed through several networks and linked to the cloud makes them more susceptible to security risks and breaches. Application security is therefore extremely important.

Cloud Security

The protection of cloud computing systems is the topic of a subfield of cyber security termed "cloud security." Keeping data secure and private across internet platforms, technology, and applications is part of this. Together, all sized businesses, enterprises, and cloud service providers cooperate to protect all the mentioned systems.

Mobile Security

The measures put in place to protect confidential information transferred and stored on pcs, phones, tablets, smartwatches, and other portable devices are referred to as "mobile device security." Mobile device security's main goal is to stop unethical users from accessing corporate or individual networks.

Network Security

Network security protects your network and data against hackers, breaches, and other threats. Network security covers a variety of topics such as network access, antivirus, application security, and more. Business organizations are shielded from substantial losses caused by a data leak or other related catastrophes and administrative costs are reduced thanks to an efficient network security solution.

Data Loss Prevention

Protocols and guidelines for managing data loss as well as a recovery plan. To avoid data loss, internet connectivity and storage-related rules must be in place.
In order to protect against serious cyber security incursions, data loss prevention focuses on developing.

Infrastructure Security

Servers, data centers, network connections, and IT facilities are all protected by this security mechanism. The goal is to lessen how sensitive these systems are to fraud, theft, and other types of crime. Businesses and organizations that rely on critical services should be mindful of the dangers and take precautions to protect their operations.
After learning what is cybersecurity and its types, let’s see how to make a career in cybersecurity:
