Introduction to Cyber Security- Why is it necessary?


It can be rightfully said that today’s generation lives on the internet and we general users are not aware how these random bits of ones and zeros packets reach us safely.

For hackers it is a golden age with so many access points and IP addresses and tons of data traffic due to which black hat hackers are having a field day. Cyber-attacks are evolving exponentially whereas hackers are becoming smarter day by day.

Basic cyber threats are of various kinds as listed.

  • Malware
  • Phishing
  • Password Attacks
  • Ddos Attacks
  • Man in the middle
  • Mal-Advertising

Regardless of the above mentioned threats, rogue software’s/scripts are being developed every day by hackers.

Cyber security has evolved into a field where computers, software and electronic data needs be protected to avoid manipulation. The need for cyber security personnel is increasing day by day because of the dependency on computers, technological devices and software. Cyber security is evolving due to rapid technology advancement. Analysts need to rapidly keep themselves up to date that they can tackle issues that can effect organizations and their operations. As physical machines are being software governed, resulting in creating havoc. Due to recent events in the cyber world from Stuxnet (Olympic Games) to financial application frauds the cyber security teams need to be on top of their game to protect their organizations.

Our daily life, economic vitality and national security depends on a stable, safe and resilient cyber security force. Cyberspace is particularly difficult to secure due to a number of factors: One is majorly of the cyber-attacks can take place from anywhere in the world, the linkages between cyberspace and physical systems is also a major factor. These days’ air gaps are also vulnerable as social engineering plays its own role in cyber-attacks.

The different systems that are majorly at risk with cyber-attacks are financial systems, industrial equipment, aviation, consumer devices, corporations, government organizations and the list goes on. Technology has seeped into our lives at every turn. Even house hold activities from turning the lights on/off to drawing the curtains in your room it is all done through a software that can be vulnerable and can leak private data of your environment. These days cyber security analysts are a need in the technological world for securing your environments from black hat hackers.

The first hack took place in 1908 .A magician and inventor Nevil Maskelyne disrupts John Ambrose Fleming’s public demonstration of Guglielmo Marconi’s purportedly secure wireless telegraphy technology, sending insulting Morse code messages through the auditorium’s projector.

The most famous lurking ground for hackers is the dark web. That’s where they get their core raw data from.

Branches of Cyber security

There are many multiple fields in cyber security but the most demanded ones are the following.

Cyber security engineers

They are mostly concerned with the background of technical development. The language they are mostly well versed in are python and java. They are able to read what is inside the code and able to study where the vulnerabilities reside in the system and what are the factors effecting the performance of the system. Thereafter allocating the issue and tweaking it that vulnerabilities and performance issues can be resolved.


The abbreviation CISO stands for Chief information security officer . The CISO is concerned with the organizations cyber security concerns and devising strategies to protect the integrity of the institute. In this age of technology CISO are must have in any organization. CISO in the past were not that necessary even technical engineers and programmers used to play a side role .Now organizations need a specific CISO as mentioned above. Why? Because these CISO officers are trained to handle security breaches and know the counter tactics that need to be taken to protect the organization. These days’ organizational top tier need people that show them the flaws in their system that they can be rectified before a breach actually occurs. If a breach takes place it’s a million times more costly if the issues are not addressed before hand. CISO are more future minded and their requirement is to grow at every step.

Penetration Testing

The pen-testers are the people that come and test your organizations software and validate whether it can be broken or withstand external or internal breaches. Pen testers are the ones that upgrade your cyber security boundaries and evaluate it. In the evaluation process they study your code and try to access the system for vulnerabilities. If any vulnerabilities are detected the pen testers will take evasive measures or even can give detailed report of flaws that organizations can bring in cyber security engineers or analyst to fix them and make sure that an outside breach doesn’t take place.

Security Architect

They play a vital role in the IT department of an organization. You’ll design systems, manage employees and help evolve the security needs of the organization. A security architect can achieve senior level positions only when he has become extensively experienced in the cyber security field. As a security designer, you’ll be charged of planning security frameworks to prevent malware, hacker intrusions and Denial of Service assaults. When the framework is set up, you should test for any vulnerabilities and review the whole framework. To completely test your framework, you may need to contract an outside adviser who can run an intensive penetration test to guarantee that the framework is secure from outside assaults.

Forensic Expert

Forensic experts are a need in both corporate and governmental organizations. As a computer forensic expert, you will have a great deal of duty on your shoulders. After a security breach, you will be called to investigate the break to decide how it occurred and endeavor to store up the proof to demonstrate who executed the breach. You should be careful and smart with how you handle the evidence and even how you train the first respondents to manage any electronics, for example, PCs, hard drives or external portable drives. On the off chance that any gadgets are messed with and not following proper protocol, your examination may lose data or break the chain of proof, rendering any proof spoiled and inadmissible in a court.

These are the major fields in the cyber security division that cyber security analyst can spread into.
