So, if you are a beginner, & wondering about cybersecurity what is it! We are going to cover each section in detail, beginning with what is cybersecurity and why is it important! 

Down the post you will get visibility on-

And much more…

Let’s start by exploring, what is cybersecurity?

What is Cybersecurity?

Cybersecurity is the art of protecting networks, devices, and data against unauthorized, unethical access for criminal or fraudulent use and the practice of guaranteeing network & data confidentiality. A subset of IT security, cybersecurity focuses primarily on protecting digital assets from vectors of digital attacks. 

With so many access points, public IPs and constant traffic, and tons of data to exploit, hackers are exploiting vulnerabilities and creating malicious software for the same.

However, cybersecurity is based on detecting, mitigating, and remediating cyber attacks with advanced technology solutions. The industry’s lack of quality cybersecurity professionals is one of the primary reasons businesses cannot sustain increasing cyberattacks.  

International Data Corporation (IDC) says AI in the cybersecurity market is growing at a CAGR of 23.6% and will reach a market value of $46.3 billion in 2027

In the next section, we are going to help you understand how cybersecurity is important for businesses.

Importance of Cybersecurity In Business

Cybercriminals attempt to access, change, or destroy data, extort money from users or the organization, or aim to disrupt typical business environments & operations. 

Cybersecurity measures are designed to combat security threats against networked systems and applications. IBM says the global average cost of a data breach in 2023 was USD 4.45 million, a 15% increase over 3 years in the United States. These costs include economic costs (cost of repairing damaged systems, cost of downtime, and lost revenue), regulatory costs (including regulatory fines or sanctions costs), and reputational costs (loss of consumer trust and loss of customer loyalty).

Cyber attackers target customers’ personally identifiable information (PII) —including names, addresses, national identification numbers, and credit card details— and then sell these records on the dark web & underground digital marketplaces. Compromised PII often leads to a significant loss of brand reputation & loyal customer trust, imposition of regulatory fines, and legal action.

Organizations with a comprehensive cybersecurity strategy, governed by best practices and automated using advanced analytics, artificial intelligence (AI), and machine learning, can fight against malicious cyber threats to create a secure web environment & protect their hard-earned brand reputation.

Well, hope you get a clear picture of cybersecurity and why we need it!

Let’s move on to the next section and explore critical cybersecurity subdomains & CIA Triad to understand cybersecurity and its importance!

Cybersecurity Subdomains & CIA Triad

The core importance of cybersecurity in business is that a robust cybersecurity strategy has layers of multi-domain protection to defend and fight back against cyber-attacks and protect organization data, network, and architecture from fraudulent activities. 

To best answer the question “What is cyber security” and how cyber security works, we must divide it into a series of subdomains:

Here are the critical cybersecurity domains cybersecurity experts consider to identify potential threats and protect valuable data.

  • Network security - Subdomain refers to security measures consisting of the policies, processes, and practices adopted to prevent, detect and monitor unauthorized access, misuse, or denial of a computer network and network-accessible resources.
  • Application security - Subdomain refers to protecting the applications software operating on-premises and in the cloud environment against various threats to minimize the chance of unauthorized access or modification of application resources.  
  • Infrastructure security - Subdomain refers to protecting the computer systems, networks, and other assets that digital infrastructure relies upon for creating a secure web environment.
  • Cloud security - Subdomain refers to creating secure cloud architectures and applications for companies that use cloud services and infrastructure. 
  • Information security - Subdomain refers to the data protection measures covering activities, and data security frameworks, such as the General Data Protection Regulation or GDPR, which aim to secure your sensitive data from unauthorized access or theft.
  • End-user education - Subdomain refers to giving business staff and teams training on the fundamentals of computer security, critical for raising awareness about industry best practices, organizational procedures and policies, monitoring, and reporting suspicious, malicious products or activities.
  • Disaster recovery/business continuity planning - Subdomain refers to practices & procedures that refer to responding to unplanned odd events, such as natural disasters, power outages, or cybersecurity attacks, with minimal disruption to key operations.
  • Storage security - Subdomain refers to the group of parameters for solid data resilience with numerous safeguards to support restoration or data recovery, minimizing the impact of a cyber-attack.
  • Mobile security - Subdomain refers to protecting organizational and personal information stored on mobile devices like tablets, smartphones, and laptops from threats like unauthorized access, device data loss or theft, malware, viruses, etc.

All the critical subdomains are an integral part of the end-to-end Cybersecurity Model to defend the network from cyberattacks that are usually aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting or hampering business operations & processes.

Next, we help you explore what is cybersecurity CIA Triad and how it plays a foundational role in security systems development to keep your data safe and secure against growing cyber threats. 

What Is Cybersecurity CIA Triad?

The CIA triad refers to an information security model comprising three principles: confidentiality, integrity, and availability. Each of these components represents a fundamental objective of information security, vital for enhancing data security posture, and helps organizations stay compliant with complex regulations, and ensures business & operation continuity.

CIA Triad  

  • Confidentiality: The confidentiality principle asserts that only authorized parties can access sensitive information and functions. It addresses the need to protect sensitive, private information from unauthorized access.
  • Integrity: The integrity principle asserts that only authorized people, authority, and means can modify, add, or remove sensitive information and functions. Example: an unauthorized user entering incorrect data into the database.
  • Availability: The availability principle asserts that systems, functions, and data must be accessible & available on-demand to authorized users based on agreed- terms & conditions.

Priority of these principles may suffer, depending on an organization’s security goals, industry, regulatory requirements, or nature of your business.

For a better understanding of what is cybersecurity and the importance of cybersecurity in business, let's explore some of the most common but critical cybersecurity threats, which are malicious attacks that seek to unlawfully access data, disrupt digital operations, or damage critical information. 

Potential Cybersecurity Threats Continually Evolving Across The Globe

Getting hacked isn’t the only threat to data confidentiality; it can also ruin their relationships with customers. The need to protect confidential information is a pressing concern at the highest levels of government and industries across the globe. There are dozens of types of cyber security threats. Let’s explore some critical ones.

  • Cyberterrorism: This threat is a politics-based attack on computer networks to cause harm and create widespread social disruption.
  • Malware: It can encompass ransomware, spyware, viruses, and worms,  install harmful software, block access to your computer resources, disrupt the system, or covertly transmit information from your data storage.
  • Trojans: Like the legendary Trojan Horse of mythology, this attack tricks users into thinking they're opening a harmless file. Instead, once the trojan is in place, it attacks the system, typically establishing a backdoor that allows access to cyber criminals.
  • Botnets: This especially hideous attack involves large-scale cyberattacks conducted by remotely controlled malware-infected devices. 
  • Adware: This threat is a form of malware, often called advertisement-supported software. The adware virus is a potentially installed unwanted program (PUP) without your permission and automatically generates unwanted advertisements.
  • SQL injection: A Structured Query Language attack inserts malicious code into a SQL-using server.
  • Phishing: Hackers use fake communications, especially e-mail, to fool the recipient into opening it and following instructions to fetch all personal information. According to the firm Lookout, the highest rate of mobile phishing in history was observed in 2022, with half of the mobile phone owners worldwide exposed to a phishing attack every quarter.
  • Man-in-the-middle attack: MITM attacks involve hackers inserting themselves into a two-person online transaction. Once succeeds, the hackers can filter out and steal confidential data. These attacks often happen on unsecured public Wi-Fi networks.
  • Denial of Service: DoS is a cyber attack that floods a computer network with an overwhelming amount of “handshake” processes, effectively overloading the systems and making them incapable of responding to user requests.

Exploring all these threats helps you understand why cybersecurity is so important to provide security solutions to help organizations drive security into the fabric of their business so they can thrive in the face of uncertainty.

Industries Under Cyber Attacks

Depending on the nature of the business, some industries are more vulnerable to cyber threats than others. An organization that holds sensitive data or personally identifiable information is a common target for hackers. Types of institutions or organizations that are most vulnerable to cyber attacks include

  • Financial Institutions: Database contains customer credit card details and bank account details.
  • Education Institutions: The database holds information on enrollment data, financial records, and personally identifiable information like names, addresses, and billing info. 
  • Government Agencies: The database contains a wide range of sensitive data, from payment information to social security plan details, budgetary information, and more.
  • Healthcare Institution: The database contains patient records such as social security numbers, billing information, and insurance claims.
  • Corporate Organizations: Database has data such as intellectual property, marketing strategies, client and employee databases, contract deals, account transfer details, and more. 

The frequency of malicious breaches is growing at a massive pace. The volume of sensitive personal and financial information stolen is higher than ever before and the industry is confronting a heavy shortage of cybersecurity professionals.

Cyber Security services, which include planning of cyber security strategies, policy development, and building security architecture, are expected to grow at a compound annual growth rate (CAGR) of 9.7% over 5 years to become a market worth over $345 billion by 2026.”
