Where Should I Start with Cybersecurity

What is Cybersecurity?

Cybersecurity refers to any technology, measure, or practice designed to prevent or mitigate the impact of cyber attacks. The goal of cybersecurity is to protect the systems, applications, computing devices, sensitive data, and financial assets of individuals and organizations from a range of threats, from simple computer viruses to sophisticated and costly ransomware attacks.

Cyber attacks can disrupt business operations, harm business interests, and even cripple an organization. The costs incurred by victims are continuously rising.

For example, according to IBM's 2023 Cost of a Data Breach Report, the average cost of a data breach in 2023 was $4.45 million, a 15% increase over the past few years. The average cost of data breaches related to ransomware was even higher, reaching $5.13 million in 2023. This does not include ransom payments, which averaged an additional $1.54 million, an 89% increase from the previous year. It is estimated that by 2025, cybercrime will cost the global economy $10.5 trillion annually.

Over the past few years, information technology has rapidly evolved, with the adoption of cloud computing, increased network complexity, remote and home working, Bring Your Own Device (BYOD), and connected devices and sensors ranging from doorbells and cars to assembly lines.

While these advancements bring significant business benefits and technological progress, they also create exponentially more attack vectors for cybercriminals.

Unsurprisingly, a recent study found a global cybersecurity workforce gap of 3.4 million people. Security teams are focusing on developing comprehensive cybersecurity strategies, leveraging advanced analytics, artificial intelligence, and automation to more effectively mitigate cyber threats.

Types of Cybersecurity

A robust cybersecurity strategy protects all layers or domains of IT infrastructure from cyber threats and cybercrime. Here are some common types of cybersecurity:

  • Critical Infrastructure Security: Protecting computer systems, applications, networks, data, and digital assets that society relies on for national security, economic health, and public safety. In the United States, the National Institute of Standards and Technology (NIST) has developed a cybersecurity framework to help IT providers in this area, and the Cybersecurity and Infrastructure Security Agency (CISA) offers further guidance.

  • Network Security: Preventing unauthorized access to network resources, detecting and stopping ongoing cyber attacks and vulnerabilities, while ensuring authorized users can safely access the network resources they need.

  • Endpoint Security: Protecting endpoints (servers, desktops, laptops, mobile devices) and their users from attacks, as well as protecting networks from adversaries who use endpoints to launch attacks. Endpoints remain a primary attack surface for cyber attacks.

  • Application Security: Protecting applications running locally and in the cloud from unauthorized access and use, and preventing hackers from exploiting design flaws or vulnerabilities to infiltrate data. Modern application development methods, like DevOps and DevSecOps, build security and security testing into the development process.

  • Cloud Security: Protecting cloud-based services and assets, including applications, data, storage, development tools, virtual servers, and cloud infrastructure. Generally, cloud security follows a shared responsibility model: the cloud provider protects the services and infrastructure used to deliver them, while customers protect their data, code, and other assets in the cloud. Details vary depending on the cloud service used.

  • Information Security: Protecting all important information of an organization (digital files and data, paper documents, physical media, even human speech) from unauthorized access, disclosure, use, or tampering.

  • Mobile Security: Includes many principles and techniques specific to smartphones and mobile devices, such as Mobile Application Management (MAM) and Enterprise Mobility Management (EMM). Recently, mobile security has been offered as part of Unified Endpoint Management (UEM) solutions, which support configuring and securing all endpoints (not just mobile devices, but also desktops, laptops, etc.) from a single console.

The Importance of Cybersecurity

Cybersecurity is crucial for both individuals and organizations because it protects the following:

  • Personal Privacy: Cybersecurity prevents personal information (such as name, address, phone number, email, bank account, social security number, etc.) from being stolen or leaked, thus avoiding risks such as identity theft, credit card fraud, ransomware, and more.

  • Business Interests: Cybersecurity protects a company’s trade secrets, patents, customer data, financial data, and more, preventing theft by competitors, damage by hackers, and legal repercussions.

  • National Security: Cybersecurity protects critical infrastructure, government agencies, military departments, and public services from attacks, terrorism, espionage, and other threats.

Challenges in Cybersecurity

Cybersecurity faces numerous challenges, including:

  • Complexity and Variety of Cyber Attacks: The types and methods of cyber attacks are constantly changing. Cybercriminals use various techniques and strategies, such as social engineering, malware, botnets, zero-day vulnerabilities, making them hard to predict and defend against.

  • Costs and Resources: Cybersecurity requires significant investment in funds and manpower to establish and maintain effective security measures and tools, such as firewalls, intrusion detection systems, encryption, authentication, backups, etc. Additionally, there is a need to continuously address growing cyber threats and regulatory requirements.

  • Talent Shortage: Cybersecurity is a highly specialized and technical field requiring skilled professionals with extensive knowledge and experience. Currently, the supply of cybersecurity talent is far from meeting demand, making recruitment and training challenging.

  • Awareness and Culture: Cybersecurity is not only a technical issue but also a human related issue. Raising security awareness and responsibility among all network users, cultivating good security habits and culture, and preventing security vulnerabilities or risks caused by negligence or ignorance are all crucial.

Conclusion

Cybersecurity faces numerous challenges. Things will get easier if we take advantage of automatic security tools. As for web application security, a web application firewall is the most necessary method to defend various attacks and threats.
