What is Cybersecurity?

Updated: Jun 24


what is Cybersecurity


Cybersecurity protects organizations, employees, and their assets from cyber threats. As cyberattacks increase in frequency, sophistication, and corporate networks grow more complex, organizations need to deploy a variety of cybersecurity solutions actively to mitigate cyber risks.


The Various Types of Cybersecurity

● Endpoint Security Endpoint security plays a vital role in implementing a zero-trust security model by securing end-user devices such as desktops and laptops. It involves deploying data and network security controls, advanced threat prevention measures like anti-phishing and anti-ransomware technologies, as well as endpoint detection and response (EDR) solutions for forensic purposes.

● Mobile Security When businesses utilize mobile devices like tablets and smartphones, they face vulnerabilities to malicious apps, zero-day exploits, phishing, and instant messaging attacks. However, mobile security actively combats these threats by implementing measures to secure operating systems and devices, which include safeguards against jailbreaking and rooting. Additionally, businesses ensure compliance by employing Mobile Device Management (MDM) solutions.


● IoT Security The use of Internet of Things (IoT) devices increases productivity while also exposing organisations to new cyber threats. IoT security safeguards these devices by discovering and categorising connected devices, implementing auto-segmentation for network control, employing Intrusion Prevention Systems (IPS) as virtual patches to prevent exploits, and enhancing firmware with small agents to prevent attacks.


● Application Security Due to their close connection to the internet, web applications make for attractive targets for threat actors. OWASP’s Top 10 list of critical web application security flaws, such as injection, broken authentication, misconfiguration, and cross-site scripting, are addressed by application security to address these issues. Additionally, it guards against malicious interactions with APIs and applications by bots and continuously updates to counter new threats.


● Zero Trust The conventional security approach centres on constructing boundaries around important assets, yet it faces shortcomings like internal threats and the eroding network perimeter caused by cloud adoption and remote work. In contrast, zero trust adopts a detailed strategy that safeguards individual resources by employing micro-segmentation, surveillance, and the enforcement of role-based access controls.


● Network Security A network security solution is crucial, as most attacks occur over networks. Among these solutions are Data Loss Prevention (DLP), Identity Access Management (IAM), Network Access Control (NAC), and Next-Generation Firewall (NGFW) application controls. Technology for preventing network threats includes intrusion detection systems (IPS), next-generation antivirus (NGAV), sandboxing, content disarming and reconstruction (CDR), network analytics, threat hunting, and automated Security Orchestration and Response (SOAR).


● Cloud Security It has become increasingly important for companies to secure their cloud computing networks as they adopt cloud computing. Organizations actively use cybersecurity solutions, controls, policies, and services to protect all aspects of their cloud deployment, including applications, data, and infrastructure. Although cloud providers offer security solutions, organizations often need to incorporate additional third-party solutions to attain enterprise-grade security in the cloud actively.


The Change in the Landscape of Cybersecurity Threats

The cyber threat landscape constantly evolves, requiring organizations to defend against current and future tools and techniques used by cybercriminals. The following generations of cyber threats have shaped the security landscape:


● In Generation I, also called the Virus generation, cyber threats targeted standalone computers. Cybersecurity experts and developers actively created antivirus programs in response to these attacks, playing a crucial role in protecting and preventing the spread of viruses during that time.


● During Generation II, also known as the network generation, cyberattacks transitioned to the internet. To counter these attacks, cybersecurity experts developed firewalls that prioritized network-level security, effectively recognizing and preventing such threats.


● In Generation III, known as the generation of the application, cyber attackers actively exploited security flaws in applications. As a result, intrusion prevention systems (IPS) gained popularity in mitigating this threat by preventing unauthorized access and shielding applications from potential attacks.


● Advanced malware that could get past conventional signature-based defences started to appear in Generation IV, also known as the “Payload generation.” Anti-bot and sandboxing solutions became necessary, adding extra layers of security to detect and counteract these novel threats.


● In the most recent stage of cyber threats, known as the Mega Generation or Generation V – large-scale, multi-vector attacks have emerged as their defining feature. These attacks require the implementation of sophisticated threat prevention solutions. To effectively protect organizations from evolving cyber threats, it is essential to deploy strong security measures, given the complexity and sophistication of these attacks.


Ransomware Ransomware has become the dominant form of malware in recent years, with attacks evolving to steal and extort data through double and triple extortion techniques. Ransomware as a Service (RaaS) has made sophisticated attacks more common. Protecting against ransomware requires robust cybersecurity strategies and solutions.


Phishing Cybercriminals predominantly rely on phishing attacks as the most common method to gain access to corporate environments. These attacks have evolved into highly sophisticated forms, often indistinguishable from legitimate emails. To effectively combat phishing, organizations need advanced cybersecurity solutions that can proactively identify and block malicious emails, ensuring robust protection against this prevalent threat.


Malware The evolution of malware has played a significant role in shaping cybersecurity threats. Modern malware is swift, stealthy, and sophisticated, rendering legacy security solutions ineffective. Prevention-focused cybersecurity solutions are necessary to mitigate the threat of advanced malware.


Logistics Attacks The rise in supply chain attacks actively exposed the limitations of perimeter-focused security strategies. Incidents such as the SolarWinds, Microsoft Exchange Server, and Kaseya hacks actively demonstrated how cybercriminals can exploit trust relationships with other organizations. To effectively protect against these attacks, organizations need to actively adopt a zero-trust approach, proactively limiting access for third-party users and continually monitoring their activities.


The Importance of an Integrated Cybersecurity Framework

With the complexity of modern environments, including sophisticated attacks, diverse endpoints, and the rise of remote work, managing cybersecurity with an array of disconnected solutions becomes overwhelming. To effectively manage cyber risks, organizations need to consolidate and streamline their cybersecurity architectures, enabling comprehensive security monitoring, policy enforcement, and risk mitigation across their entire IT infrastructure.

In conclusion, cybersecurity is a critical defence mechanism that safeguards organizations, their employees, and their valuable assets from a wide range of cyber threats. As the frequency and sophistication of cyberattacks continue to increase, it is imperative to deploy various cybersecurity solutions to effectively mitigate these risks.

The need for a consolidated cybersecurity architecture is paramount in today’s digital landscape. By implementing an integrated framework, organizations can enhance their resilience against cyber threats, protect their critical assets, and ensure the continued integrity of their operations in an increasingly interconnected world.
