Cyber Security

What is cyber security?

Cyber security is the protection to defend internet-connected devices and services from malicious attacks by hackers, spammers, and cybercriminals. The practice is used by companies to protect against phishing schemes, ransomware attacks, identity theft, data breaches, and financial losses.

We can divide cyber security into two parts one is cyber, and the other is security. Cyber refers to the technology that includes systems, networks, programs, and data.

Security is concerned with the protection of systems, networks, applications, and information. In some cases, it is also called electronic information security or information technology security.

As our world becomes more interconnected through the internet, cyber threats have become a significant concern for individuals, organizations, and governments alike.

Cyber security encompasses a wide range of measures, technologies, processes, and best practices aimed at safeguarding digital assets and ensuring the confidentiality, integrity, and availability of information.

Need for cyber security

Here are some key reasons highlighting the need for cybersecurity: 

Data privacy and confidentiality –

Personal and sensitive information is stored and transmitted digitally. Cyber security ensures that this data is kept private, restricts access, and maintains the privacy of individuals and organizations.

Preventing Financial Loss –

Cyber-attacks can cost individuals and organizations money. Cybersecurity measures help prevent financial fraud, money laundering, and other financial losses due to cybercrime.

Protecting Against Cyber ​​Threats –

The Internet is full of cyber threats such as hackers, malware, ransomware, phishing, and more. Cyber security systems help protect systems, networks, and data from these threats, preventing unauthorized access and potential damage.

Business continuity –

Many businesses rely on digital platforms for collaboration, communication, and communication. Cyber-attacks can disrupt these activities, resulting in financial losses and reputational damage. Effective cyber security ensures business continuity and reduces the impact of such a breach.

Trust and reputation –

Organizations that make cyber security a top priority demonstrate a commitment to protecting their customers’ data and privacy. This builds trust and reputation, which is essential for long-term success.

Compliance –

Many businesses are subject to cyber security laws and standards to ensure that customer information is protected. Failure to comply may result in legal penalties and reputational damage.

Applications of cyber security

Government and Defense

Securing critical infrastructure, such as power grids, transportation systems, and communication networks, to prevent potential cyber-attacks that could impact national security and public safety.

Defending government agencies and military systems against cyber espionage, data breaches, and other cyber threats.

Healthcare – 

Protecting patient medical records and personal information to ensure patient privacy and compliance with healthcare regulations.

Securing medical devices and systems to prevent unauthorized access or interference that could harm patients or compromise medical data.

Entertainment and Media –

Protecting media distribution platforms, digital content, and online streaming services from piracy, unauthorized access, and cyber-attacks.

Bots –

Nowadays, hackers utilize bots to make the server crash by overloading it with traffic from various devices. Cyber security assists in locating those false users and forcing them to end their connection.

Threat management system –

It locates computer system flaws that hackers could exploit to subvert it and optimizes all of its effects with the capacity to fix performance problems. It also provides effective control to the users about the vulnerabilities and issues that occur.

Types of Cybersecurity

There are three types of cybersecurity

  • Information security
  • Network security
  • Application Security

Information security

Information is used to protect privacy from attackers and hackers. It also helps in cases where hackers demand that users pay a ransom in exchange for their data.

Network security

Network security deals with mechanisms of privacy, availability, and authentication. in network elements used by users and contribute to denial-of-service attacks.

Application security

It focuses on protecting software and applications from possible attack threats created by flaws.
