What is Cybersecurity?

What is Cybersecurity?

Systems, networks, programs, and data are all included in the definition of cyber. Through cyber security, computers, servers, mobile devices, electronic systems, networks, and data connected to the Internet are protected from malicious attacks. Cyber and security are the two key components. "Security" protects information, systems, networks, and applications. Information technology security or electronic information security are sometimes used interchangeably. 

Now that we have covered “What is Cybersecurity,” let’s move on to the next section of the topic and understand why is cyber security important.

Why is Cybersecurity Important?

Cybersecurity is crucial because governments, military organizations, corporations, financial institutions, and medical entities handle vast amounts of data on computers and devices. This data often includes sensitive information that, if accessed without permission, can have serious consequences. Cybersecurity focuses on protecting this information and the systems used to process and store it. 

With the increasing volume and complexity of cyber attacks, organizations must prioritize safeguarding sensitive data, especially those responsible for national security, healthcare, or financial records. Cyber-attacks' threat surpasses traditional forms of terrorism, making robust cybersecurity measures essential in preserving data integrity and trust. Now that you know why is cyber security important, let’s begin exploring different types of cybersecurity.

The Different Types of Cybersecurity

Cybersecurity is a broad field covering several disciplines. It can be divided into seven main pillars:

Different Types of Cybersecurity

1. Network Security:- A network security solution identifies and blocks attacks that occur over the network. To enforce safe web use policies, these solutions contain data and access controls, including Data Loss Prevention (DLP), Identity Access Management (IAM), Network Access Control (NAC), and Next-Generation Firewall (NGFW).

2. Cloud Security:- It is becoming increasingly important for organizations to secure their cloud computing systems as they adopt cloud computing. A cloud security strategy includes cyber security solutions, controls, policies, and services that help to protect an organization’s entire cloud deployment (applications, data, infrastructure, etc.) against attack.

3. Endpoint Security:- Data should be micro-segmented whenever possible according to the zero-trust security model. Mobile workforces can be protected through endpoint security.  

4. Mobile Security:- Businesses are exposed to malicious apps, zero-day attacks, phishing, and instant messaging (IM) attacks from mobile devices such as tablets and smartphones, which are often overlooked. 

5. IoT Security:- When utilizing Internet of Things (IoT) devices, organizations can enjoy increased productivity but face new cybersecurity risks. Malicious actors actively target vulnerable devices connected to the internet, exploiting them for unauthorized access to corporate networks or incorporating them into global bot networks.

6. Application Security:- Web applications, being directly connected to the internet, are prime targets for cyber threats. Since 2007, OWASP has identified and tracked the top 10 security flaws in web applications, including injection attacks, broken authentication, misconfiguration, and cross-site scripting.

7. Zero Trust:- The traditional security model, which relies on perimeter defense, is no longer sufficient. Building walls around valuable assets, like a castle, poses challenges, including insider threats and the erosion of network perimeters due to evolving technology and remote work practices. A Zero Trust approach, which assumes that no device or user is automatically trusted and verifies access on a continuous basis, provides a more robust security strategy.

The Evolution of the Cyber Security Threat Landscape

Cyber threats constantly evolves, requiring organizations to stay vigilant against cybercriminals' latest tools and techniques.  

Generations of Cyber Threats: Over time, we have witnessed different generations of cyber threats and the corresponding solutions to combat them:  

  • Generation I (Virus): In the late 1980s, viruses targeting individual computers emerged, leading to the development of antivirus software. 
  • Generation II (Network): As cyberattacks started coming through the internet, firewalls were created to identify and block them. 
  • Generation III (Applications): Exploiting application vulnerabilities led to the widespread adoption of intrusion prevention systems (IPS). 
  • Generation IV (Payload): Advanced malware evaded traditional defenses, necessitating anti-bot and sandboxing solutions. 
  • Generation V (Mega): Each new generation rendered previous security solutions less effective, highlighting the need for Gen V cybersecurity measures.  

Supply Chain Attacks: - Traditional security efforts primarily focused on protecting applications and systems within organizations. However, a rise in supply chain attacks has shown the limitations of this approach, with cybercriminals exploiting vulnerabilities in third-party software or services used by organizations.  

Ransomware: -Ransomware has gained prominence in recent years as a dominant form of malware. The widespread impact of incidents like the WannaCry outbreak highlighted the profitability of ransomware attacks, leading to an increase in such campaigns.  

Phishing:- Phishing attacks remain a common and highly effective method for cybercriminals to gain unauthorized access to corporate environments. These attacks have become more sophisticated, relying on social engineering techniques to trick users into clicking malicious links or opening harmful attachments.  

Malware:- The evolution of malware defines the different generations of cyberattacks. Cybercriminals constantly innovate to overcome the latest security technologies, creating a perpetual cat-and-mouse game between attackers and defenders.  To protect against the ever-changing cyber threat landscape, organizations must adopt advanced cybersecurity measures and stay informed about emerging threats and best practices. 

Cybersecurity Myths: Debunking Common Misconceptions

In cybersecurity, numerous myths and misconceptions have emerged. These myths can lead to complacency and leave individuals and organizations vulnerable to cyber threats if left unaddressed. Let's debunk some of the most prevalent cybersecurity myths:

Myth 1: "I'm not a target, so I don't need to worry about cybersecurity."
