Cyber Security

by Shamiyal Sheraz

Cybersecurity is the name for the Safeguards taken to avoid or reduce disruption from the attack on data, computers, and mobile devices. Security Breaches can occur when we use paper Records, send information using a fax machines and even verbally.

The Internet has made the world smaller in many ways but it has also opened us to influence that has never before been so varied and so many challenging. As fast as security grew, the hacking world grew faster.

There are two ways of looking at the issue of cybersecurity. One is that company that provides cloud computing do that and only that so these companies will be extremely well-secured with the latest in the cutting edge encryption technologies

What is cybersecurity?

It’s been protected by internet-connected systems including Hardware, Software, and data from cyber-attack. In computing, Context Security comprises Cyber-security and physical security both are used by enterprises to safe against unauthorized access to the data center and other computerized systems. The security which is designed to maintain confidentiality, integrity, and availability of data is a subset of cybersecurity. A successful cybersecurity approach has multiple layers of protection spread across the computers, networks, programs, or data that one intends to keep safe. In an organization, the people, processes, and technology must all complement one another to create an effective defense from cyber-attacks. A unified threat management system can automate integrations across select Cisco Security products and accelerate key security operations functions: detection, investigation, and remediation.


Users must understand and comply with basic data security principles like choosing strong passwords, being wary of attachments in email, and backing up data


Associations must have a system for how they manage both endeavored and effective digital assaults. One very much regarded structure can control you. It clarifies how you can recognize assaults, ensure frameworks, distinguish and react to dangers, and recoup from fruitful assaults.


Technology is essential to giving organizations and individuals the computer security tools needed to protect themselves from cyber-attacks. Three main entities must be protected: endpoint devices like computers, smart devices, and routers; networks; and the cloud. Common technology used to protect these entities include next-generation firewalls, DNS filtering, malware protection, antivirus software, and email security solutions.

Why do we need cybersecurity?

 The range of operating cybersecurity involves protecting information and system from major cyber threats. These threats take many forms. Keeping pace with cybersecurity strategy and operations can be a challenge, particularly in government and enterprise networks where there is most innovative form, cyber threat often take aim at secret political and military assets of a nation or its people.

Some of these Common Threats are

Cyber Terrorism

Innovative use of information technology by terrorist groups to further their political agenda. It took the form of an attack on the network’s computer systems and Telecommunication Infrastructure.

Cyber Warfare

It involves nation-state using information technology to go through other national networks to cause damage.

In the US and many other people live in a society Cyber Warfare is acknowledged as the fifth domain of Warfare. Cyber-attacks Warfare is primarily executed by hackers who are well trained in the use of benefit the quality of detailed computer networks that comprise data and degrade communication to interrupt commerce.

 Who are cybercriminals?

  • Cyber-criminals are those who conduct such acts
  • Gaining unauthorized access to a computer system
  • Cyber talking
  • Credit card frauds

Types of Cyber Criminals

Black Hat Criminals

Black Hat hackers are criminals who break into computer networks with malicious intent. They may also release malware that destroys files, holds computers hostage, or steals passwords, credit card numbers, and other personal information

Black Hat Criminals earn profit from crime

Grey Hat

A grey hat hacker is an individual who employs illegal means to discover threats even though he/she does not share the malicious intent commonly attributed to black hat hackers. Grey hat hackers occupy the middle ground that lies between white hat hackers who aim to protect systems and networks from attacks and black hat hackers who exploit vulnerabilities for malicious gain. In essence, a grey hat hacker looks for vulnerabilities without the hardware or software manufacturer’s permission to spread awareness about his/her findings.

White Hat

A White Hat hacker tests systems and networks by trying to break into them. They are hackers, but their talents are being used to improve Cyber Security. Being hackers, they are familiar with the tactics that malicious hackers use to compromise systems; White Hat hackers try to find the vulnerabilities before the bad guys do.

White Hat hackers are also called “Ethical Hackers” or “Certified Ethical Hackers.” In some instances, White Hat hackers assume other Cyber Security titles within an organization.

  • Cybersecurity analyst
  • Information security analyst
  • Intrusion detection analyst
  • IT security engineer
  • IT security administrator
  • Network security analyst
  • Penetration tester

Suicide Hackers

Not worried about facing jails terms or any other punishments. The concept of suicide hackers is the same as suicide bombers. The suicide bombers know that if they can blast the bomb they can also kill the people but they can do that for revenge and for money etc.

Like the same, the suicide hackers know that if they can hack the system, website, etc. they can be caught by the cyber police. But they can do this.

They can do this for two reasons. First to take revenge from their big enemies and the second one is for money. Someone takes a lot of money for them and tells them that he/she can also take care of their family etc. if they can complete his/her demand for the hacking website and for hacking system etc.

Who is a Cybersecurity Expert?

Cybersecurity Experts are those skilled people who keeps checking and performing safety measures on computer systems. Their job is to protect all the computers in the system from being hacked and data breach.

Domains is cyber security?

  • Assets Security
  • Security Architecture and Engineering
  • Communication and Network
  • Identify and Access Management
  • Security Operations (Day to day Monitor Operation)
  • Security assessment and testing
  • Software Development Security
  • Security and Risk Management
