What is cyber security definition


  • Cyber security is the practice of protecting computer networks from unauthorized access, use, disclosure, disruption, modification.
  • Cybersecurity is the protection of information technology systems against cyber threats.
  • Cybersecurity is the practice of securing computers, networks, software, data, and other IT assets against attacks, intrusions, misuse, and unauthorized access.
  • Cybersecurity is the science of preventing unauthorized access to computer networks and their resources.
  • Cybersecurity is the set of practices that protect organizations’ information technology infrastructure from damage or loss resulting from malicious activities.
  • Cybersecurity is the study of methods for defending organizations’ information technology infrastructures from attack.

Why is cyber security important for us ?

Costs of Cyber security Breaches are rising.

  • Cybersecurity is becoming increasingly expensive. In 2016, the cost of data breach incidents was $4 billion. By 2020, that number could reach over $6 billion. This increase is due to the fact that companies are spending more money on cybersecurity measures.
  • Companies are investing in cybersecurity solutions to protect their networks from hackers. According to Gartner, the number of organizations using cloud-based security services increased by 50% between 2015 and 2017.
  • Cloud-based security solutions provide better protection against cyber threats than traditional methods. They can monitor network activity, detect suspicious behavior, and prevent attacks before they occur.

Cyber security is a critical level issue ?

  • Cybersecurity is a critical, board level issue that impacts almost every business today. In fact, according to Gartner’s 2018 Hype Cycle for Emerging Technologies, cybersecurity has moved from being a hype cycle peak to becoming a mainstream technology. This means that cybersecurity is now considered a strategic priority for businesses across industries.
  • The threat landscape is constantly changing. New threats emerge daily, and existing ones evolve into new forms. As a result, organizations need to be able to adapt their cybersecurity strategies to stay ahead of these changes. To do this, they need to have a clear understanding of how cyberattacks work and what steps can be taken to mitigate them.
  • Organizations are increasingly adopting cloud computing platforms to store data and applications. However, this presents a risk to companies because many cloud providers lack robust security measures. If cloud services are compromised, sensitive information could be exposed.
  • Businesses need to adopt a holistic approach to cybersecurity. They should not rely solely on perimeter defenses to protect against attacks. Instead, they should focus on protecting access points (e.g., firewalls) and internal systems (e.g., network devices).
  • Companies need to ensure that their employees understand the importance of cybersecurity. Employees who don’t know about cybersecurity risks may inadvertently expose company data to hackers.
  • Security professionals need to take a proactive role in helping companies implement effective cybersecurity solutions. They should assess the current state of cybersecurity at each organization and identify gaps in the security posture. Then, they should help develop plans to address those issues.

Is a Cyber crime a big Business ?

  • Cyber Crime
    The term cybercrime refers to criminal activity that takes place over computer networks. This includes everything from identity theft to credit card fraud. In recent years, cybercrime has become increasingly sophisticated and difficult to prevent. Criminals are constantly developing new ways to steal your personal information and financial data. They can use this information to commit other crimes against you.
  • Identity Theft
    Identity theft is the fastest-growing type of cybercrime. It involves criminals using your personal information to open fraudulent accounts in your name, then drain your bank account or spend your money. You may never find out who did this to you until it’s too late.
  • Credit Card Fraud
    Credit card fraud is the biggest problem facing banks today. Criminals have figured out how to hack into merchant systems and redirect transactions through their own cards

Types of Cyber Threats.

  • Ransomware
    Ransomware is a type of malware that holds your data hostage until you pay them money. This can be anything from a few dollars to thousands of dollars. Once they have your information, they may demand payment through Bitcoin, gift cards, or other methods. They then use this information to extort money from their victims.
  • Botnets
    A botnet is a collection of compromised computers used to send spam, steal personal information, or perform DDoS attacks. These are often run out of someone’s home who has no idea what they are doing.
  • Malware
    Malware is any software designed to infiltrate a computer system without permission. Malware includes viruses, worms, Trojan horses, spyware, adware, crime ware, and rootkits
Cyber security is the practice of protecting computer networks from unauthorized access, use, disclosure, disruption, modification, or destruction (UDM)

5 types of Cyber Security

1.Network Security.

  • Firewall
    A firewall is a network device that controls incoming and outgoing traffic at a computer network boundary. A firewall can be used to protect computers from unauthorized access, prevent attacks from outside sources, and provide secure communications between trusted networks.
  • Intrusion Detection System (IDS)
    An intrusion detection system (IDS) monitors network traffic and alerts administrators if any suspicious activity occurs. An IDS may use pattern matching techniques to identify known attack patterns.
  • Antivirus Software
    Antivirus software scans files before they are opened or executed on your computer. This helps detect viruses and other malicious code.

2.Cloud Security.

  • Cloud Security
    The cloud is a term that describes a collection of remote servers connected over the internet. These servers are used to store data and provide services to users. The cloud is becoming increasingly popular due to its flexibility and scalability. There are many benefits to using the cloud including cost savings, increased efficiency, and access from anywhere. However, this type of technology comes with risks. In order to protect your business against cyber attacks, you need to have a secure cloud environment.
  • Anti-Virus Software
    Anti-virus software is a computer program that scans files for viruses. This allows computers to stay protected from malware. Malware includes programs that cause harm to a computer user’s privacy or damage their hardware. Anti-virus software works by scanning files for malicious code. If any suspicious activity is detected, the anti-virus application notifies the user and takes action.

3.IOT Security.

  • IoT Security
    The Internet of Things (IoT) is a network of physical objects or “things” embedded with electronics, software, sensors, actuators, and connectivity that enables these things to collect and exchange data via cloud-based services. This can include anything from smart home devices to industrial equipment.
  • IoT Security Threats
    There are many different types of threats that can affect IoT devices. These range from simple malware attacks to more complex cyberattacks. Malware includes viruses, worms, trojans, rootkits, adware, spyware, and other malicious programs. Cyberattacks include phishing, social engineering, brute force hacking, denial of service attacks, and distributed denial of service attacks.
  • IoT Security Solutions
    In order to protect IoT devices from these threats, organizations need to implement solutions that address each type of threat. Some examples of IoT security solutions include firewalls, intrusion detection systems, anti-malware tools, access control lists, and encryption technologies.

4.Application Security.

  • Application Security
    The application security of your website is what determines how safe your customers are while using your site. There are many ways that hackers can gain access to your customer’s information, including through SQL injection attacks. This type of attack occurs when malicious code is injected into a database query string. Hackers may use this method to steal user data from your database.
  • Session Management
    Session management is the process of managing session-based authentication. A session is a unique identifier assigned to each visitor to your website. When a visitor logs in, their session ID is stored in a cookie on their computer. If they close their browser without logging out, then their session ID remains active until they log back in.
  • Cross Site Scripting (XSS)
    Cross-site scripting (XSS) is a common web vulnerability that allows attackers to inject client-side script into the pages viewed by other users. XSS exploits occur when a user submits content containing HTML tags that contain executable scripts. These scripts can allow an attacker to take control over the affected system.

5.Infrestacture Cyber Security.

  • Critical Infrastructure Cyber Security (CISC)
    The CISC program provides federal assistance to state and local governments that are developing plans to protect critical infrastructure from cyber attacks. This includes power grids, water treatment facilities, transportation systems, financial institutions, healthcare providers, emergency services, and other public safety organizations.
  • National Cybersecurity Center of Excellence (NCCOE)
    The NCCOE is a partnership between the Department of Homeland Security (DHS), the Office of Management and Budget (OMB), and the General Services Administration (GSA). The NCCOE was created to provide cybersecurity training and education for government employees and contractors.
  • National Initiative for Cybersecurity Education (NICE)
    The NICE is a collaboration between DHS, OMB, GSA, and the private sector. Its mission is to improve the nation’s ability to prevent, detect, respond to, and recover from cybersecurity incidents.
