In the media, the term "cyber security" is often used broadly to encompass protection against various forms of cybercrime, including identity theft and digital warfare at a global scale. Although these descriptions are accurate, they may not fully convey the essence of cyber security to those who lack a background in computer science or experience in the digital industry.
According to Cisco Systems, a leading technology conglomerate specializing in networking, cloud services, and security, cyber security is defined as "...the practice of safeguarding systems, networks, and programs from digital attacks. These cyberattacks typically aim to gain unauthorized access, manipulate or destroy sensitive information, extort money from users, or disrupt normal business operations."
Why is Cybersecurity Crucial?
In today's digital era, the importance of cybersecurity cannot be overstated. A single security breach has the potential to expose the personal information of millions of individuals, leading to significant financial consequences for companies and eroding the trust of customers. Therefore, safeguarding against spammers and cybercriminals through effective cybersecurity measures is paramount for both businesses and individuals.
The Magnitude of Cybersecurity Threats
Forbes predicts that 2022 will bring forth a multitude of diverse and daunting cybersecurity challenges, ranging from disruptions in the supply chain to increased risks associated with smart devices, along with the ongoing scarcity of cybersecurity talent.
According to Cybercrime Magazine, cybercrime is projected to cost the world a staggering $10.5 trillion annually by 2025. Moreover, global cybercrime costs are expected to rise by nearly 15 percent each year over the next four years.
Factors such as the pandemic, cryptocurrency, and the rise of remote work have created a fertile ground for criminals to exploit.
Understanding Cybersecurity and its Challenges
Cybersecurity encompasses the use of technologies, processes, and methodologies to defend computer systems, data, and networks against various forms of attacks. To gain a comprehensive understanding of what cyber security entails and how it functions, it can be broken down into several subdomains:
Application Security
Application security focuses on implementing robust defenses within an organization's software and services to protect against a wide range of threats. Cybersecurity experts in this subdomain write secure code, design secure application architectures, and employ stringent data input validation techniques to minimize the risk of unauthorized access or modification of application resources.
Cloud Security
Cloud security involves creating secure architectures and applications for companies that utilize cloud service providers like Amazon Web Services, Google, Azure, Rackspace, and others.
Identity Management and Data Security
This subdomain encompasses activities, frameworks, and processes that facilitate authorization and authentication of authorized individuals to an organization's information systems. It involves implementing robust information storage mechanisms to protect data during transmission or while residing on servers or computers. Additionally, this subdomain emphasizes the use of authentication protocols, including two-factor or multi-factor authentication.
Mobile Security
As the reliance on mobile devices continues to grow, mobile security has become increasingly significant. This subdomain focuses on safeguarding organizational and personal information stored on mobile devices such as tablets, cell phones, and laptops from various threats, including unauthorized access, device loss or theft, malware, and viruses. Authentication measures and user education play a crucial role in enhancing mobile security.
Network Security
Network security encompasses the hardware and software measures in place to protect networks and infrastructure from disruptions, unauthorized access, and other forms of abuse. It aims to safeguard organizational assets against a wide range of threats originating from within or outside the organization.
Disaster Recovery and Business Continuity Planning
Not all threats are posed by humans. The subdomain of Disaster Recovery (DR) and Business Continuity (BC) focuses on processes, alerts, monitoring, and plans designed to help organizations prepare for and maintain the operation of their critical systems during and after incidents such as power outages, fires, or natural disasters. It involves resuming and recovering lost operations and systems in the aftermath of an incident.
User Education
Knowledge is power, and raising staff awareness of cyber threats is crucial in the realm of cybersecurity. Providing business staff with training on computer security fundamentals plays a vital role in promoting awareness about industry best practices, organizational procedures, and policies, and monitoring, and reporting suspicious and malicious activities. This subdomain covers cybersecurity-related classes, programs, and certifications.
Understanding Cybersecurity and Types of Cyber Threats
Cybercrime refers to any unauthorized activity involving a computer, device, or network. Cybercrime is generally classified into three categories: computer-assisted crimes, crimes where the computer itself is the target, and crimes where the computer is incidental to the crime rather than the primary target.
Here is a list of common cyber threats:
Cyberterrorism: Politically motivated attacks on computers and information technology aimed at causing harm and widespread social disruption.
Malware: This encompasses ransomware, spyware, viruses, and worms, which can install harmful software, block access to computer resources, disrupt systems, or covertly transmit information.
Trojans: Deceptive attacks that trick users into opening seemingly harmless files, which then provide unauthorized access to cyber criminals.
Botnets: Large-scale cyberattacks conducted by remotely controlled malware-infected devices, creating a network of compromised computers.
Adware: A form of malware that generates unwanted online advertisements, often installed without permission.
SQL injection: An attack that inserts malicious code into a SQL-using server.
Phishing: Hackers use false communications, typically through email, to deceive recipients into sharing personal information or installing malware.
Man-in-the-middle attack: Hackers intercept and insert themselves into a two-person online transaction to filter and steal desired data, often occurring on unsecured public Wi-Fi networks.
Denial of Service (DoS): An attack that overwhelms a network or computer with excessive "handshake" processes, rendering the system unable to respond to user requests.
As data breaches, hacking, and cybercrime continue to rise, companies increasingly rely on cyber security experts to identify potential threats and safeguard valuable data. This growing demand is reflected in the projected growth of the cyber security market, expected to reach $345 billion by 2026 with a Compound Annual Growth Rate (CAGR) of 9.7% from 2021 to 2026.
The Benefits of Cybersecurity
The cyber security industry is primarily focused on protecting devices and systems from attackers. Although the technical aspects may be complex, the effects are easier to grasp. Without the tireless work of cyber security professionals, many websites would be rendered inaccessible due to constant denial-of-service attack attempts.
