Importance of Cyber Security in 2020 and Why should we learn it?
“By 2025 every organization in the world will be under the some kind of Cyber Attack “
Cyber Security is the protection of internet-connected systems including Hardware, Softwares, and Data. According to the market survey, there will be a shortage of Cybersecurity professionals by 2025 and highly paid Cybersecurity jobs will come to the job market as companies will be willing to invest money to maintain confidentiality, Integrity, and Availability of their data. So the importance of cybersecurity in 2020 is very very high.
Data is the most important thing out there e.g. Anywhere in the world we need to share our data e.g. while checking in a hotel we have to provide our credit card details, which contains
our names, phone numbers, or maybe some times social media information. So attackers can get all the possible information and eventually try to hack the password of our account.
That’s where Cybersecurity becomes important.
The duty of Cybersecurity professionals is to protect my business ( online business ). If my business website is under cyber attack, it may not function in a proper way. So as a Cyber Security professional my responsibility is to protect the website so that it functions properly and my business is up and running. Cybersecurity professionals contribute to the business bottom-line
About 20% of businesses will be improved using cybersecurity implementation.
Key Concepts of Cyber Security
- Availability: Data being available for genuine users for genuine business purposes, then we call it data availability e.g. every time we log in to our Gmail server it verifies if the combination of username and password is matching correctly. While logging into Gmail some bot sends a wrong username and password anonymously to log into an email account and hack the email. The speed goos down and availability is compromised.
- Integrity: If between the sender and receiver someone modifies the data and the receiver knows about it. Any software we try to download from the web. We want to ensure that the data I am downloading is safe. E.g. lets transfer 100$ from person A to person B. Integrity confirms there is no unauthorized modification.
- Confidentiality: When we send a message from person A to person B, no one should be able to understand the message. When you log in to your banking application, no one should be able to understand the password you use to login.
Important steps for maintaining the confidentiality
Encryption: Technique to maintain confidentiality. It’s all about converting a plain text to the ciphertext in a high-level context.
Man in the Middle Attack: If somebody in between squandered the message from sender to receiver.
As long as these three above principles are maintained then we call there is cybersecurity present in the system.
As the importance of Cybersecurity is very high in 2020 and we need to take proper measures to become a cybersecurity professional and we must have these basic skills.
- Basic computer Skills e.g. Basic understanding of coding, database, Operating system, etc
- Basic knowledge of Networking
- Understanding basic Cyber Security measures ( Confidentiality, Integrity, and Availability )
Cybersecurity is needed when we are trying to protect a system that is connected to the internet or any other network ( LAN, WAN, MAN, etc ) or hosted in Cloud. If the system is not connected to the internet or any other network or system we don’t need to implement cybersecurity measures. If a system is standalone and not connected to the internet then the kind of security measures needed is called information security.
Securing Systems: Applied Security Architecture and Threat Models
Internet attack on computer systems is pervasive. It can take from less than a minute to as much as eight hours for an unprotected machine connected to the Internet to be completely compromised..

We need to learn how to put layers for the defense to protect our system. Physical Security also a part of cybersecurity e.g. data centers need to be protected.
Why do we need Cybersecurity and What is the importance of Cybersecurity in 2020?
Cybersecurity is one of the most secure jobs in the industry. The importance of Cybersecurity in 2020 is very high to keep people’s data safe. For any System, whether it’s a banking application to maintain financial data or Healthcare data safe, we need to understand, learn, and develop cybersecurity skills.
There are hackers outside to penetrate the data. There are three main types of hackers
- Blackhat Hackers: Use vulnerabilities of the interconnected applications to threaten the organization for their personal benefit.
- Whitehat Hackers/ Ethical hackers: They try to defend the organization with their hacking skills.
- Greyhat Hacker: Who turns from Black to White. They have both the skills of Black Hat and Whitehat Hacking
Blackhat and Greyhat hackers want to create chaos by disrupting the organization’s critical infrastructure. They target organizations and damage them financially or damage their reputation. This is a part of cyber Crime. There are different types of Cybercrimes.
Computer-Assisted Crimes: Using the help of a computer e.g. Denial of service or distributed denial of service.
It is expected that by 2025 every organization will be in a situation of some kind of cyber attack.
So let’s discuss some of the cyber attacks.
Possible attacks against organizations?
Wannacry Ransomware
This cyberattack affected some of the prestigious organizations of the USA totaling the loss of 300 million US dollars. This incident happened in 2017. They get access to the machine and decrypt the data and when the user wants to access the data it asks for money. Unless you pay within a certain time the data will be lost.
Botnets Attacks
If the attackers want to bring down the email server by trying random usernames and passwords. e.g. WordPress website can get hacked easily by the hacker who can try to hack the username and password. Hackers can try from different machines with different IP-address which are also called rogue machines or bots. So multiple hackers present within a network of different rogue machines create BOTNET and the attack they do is called Botnets attacks.
Phishing Attack
This is a type ofSocial engineering attack hacker will try to trick legitimate business usage by accessing and downloading a document that is confidential. Most of business entrepreneurs know how to run the business but they have no clue how to protect the system. E.g Ukrain Powergrid attack. This was a state-sponsored attack and more sophisticated than normal attacks.
To prove a hacker guilty we need to understand the “Chain of Custody” to get the log files as proof e.g Operating System Logs, Database Logs for any organization. Based on the behavior of the logs and if there is any abnormal behavior, we can identify if there is any attack happened. To understand this concept better, we also need to understand Forensic security which is a part of Cybersecurity.
