What Is Cybersecurity?

We live in a digital age where systems and networks are more interconnected than ever. The age of digital innovation and rapid technological advancement has catapulted all businesses, regardless of size, into a sphere of digital threat exposure. With growing dependency on digital systems, systems can also rapidly become compromised.

As systems become more interconnected, networks, devices, and applications become more vulnerable. Cybersecurity helps protect vulnerable systems by placing barriers around networks and applications, and protecting sensitive data from unauthorized users. While cybersecurity serves multiple purposes across an organization, at its essence, it serves to protect organizations from exposure and potential attack.

Different Aspects of Cybersecurity

Cybersecurity is highly complex, and entails a multifaceted, layered, approach that functions across and encompasses all elements of a digital environment. Modern businesses operate using a multitude of digital resources, and as a result, they have complex digital environments that require similarly complex protection.

Infrastructure Security

In addition to cyber warfare and terrorism, the protection of vital systems and resources, such as energy, healthcare, and communications, is of prime importance to national defense and economic stability of a country. Without such protection, systems of Modus Operandi would be compromised, leading to a loss of control and severe repercussions.

Application Security

Not all applications are victim to Cybersecurity Attack (CSA), but all applications have the potential to be, and thus the potential to be attractive to unauthorized users. Application security is not a cure to the application, but rather a means by which applications can become more secure and consequently reduce the potential that they can become cyber attacks.

Network Security

Network security is protecting the systems that businesses use daily. This includes protecting against unauthorized access via firewalls, intrusion detection, data encryption, and controlled access to private networks.

As the targets of the majority of cyberattacks, networks are the most defensively critical layers of the system.

Cloud Security

As the need to store company data in the cloud become more prevalent, securing that data in the cloud system has become a necessity. Cloud security protects cloud-based applications and the data stored within them from breaches and unauthorized access.

While the cloud provides flexibility, it is virtually useless if the company has not properly put in place the necessary safeguards.

Internet of Things (IoT) Security

Connected devices such as smart appliances, sensors, industrial machines, and vehicles pose new cybersecurity hurdles. Protecting those devices from exploitation and unauthorized access is the main focus of IoT security.

The continual collection and distribution of irreplaceable data by IoT devices mandates the need to secure them.

What Exactly Is a Cyberattack?

Cyberattacks are hostile attempts to gain unauthorized access to, and potentially steal information from, a computer system, a computer network, or an entire system. They are meant to disrupt normal operations, andor to inflict damage in other ways.

While there are many methods to perform a cyberattack, the goals can usually be distilled to a few categories: the theft of money, espionage, data destruction, or ransomware.

The Most Common Cybersecurity Threats Businesses Face

Cyber threats can come in many forms, however, there are a select few methods that are more prevalent, and that are due to their efficacy and evolutionary characteristics.

Malware

Malware is a term used for many types of application software designed to damage computer systems, or to steal sensitive information. Types of malware include, but are not limited to, data-wiping viruses, ransomware, spyware, computer worms, and Trojans.

Once malware breaks into a system, it can collect information, destroy files, or completely lock users out without being detected.

Phishing

Phishing is an attempt to collect personally sensitive information by masquerading as a trusted entity. Fraudulent messages (usually) sent by email that appear to be from a bank, a company, or some other official-looking organization can be the source of the attack.

Phishing messages can capture passwords, banking information, and other sensitive data about an organization.

Man-in-the-Middle Attacks

In a Man-in-the-Middle attack, one of the two communicating parties is not aware that the other party is in control of the data. The attacker is positioned to intercept communication between the two parties.

While an attacker can target any network, public Wi-Fi networks are more common, especially when an attacker can use weak encryption to make the data easier to intercept. In this way, an attacker can capture login credentials, payment information, messages, etc.

Denial-of-Service (DoS) Attacks

DoS attacks aim to render a target system inoperable by flooding it with more traffic than the system can handle.

The purpose of DoS attacks is to disrupt normal operations. Disruption of a target system can make websites inaccessible, and all services it provides may become unavailable.

The Need for Cyber Resilience

The cybersecurity landscape has evolved. Now, organizations are not only focused on preventing attacks, but also on how quickly the organization can respond, recover, and continue operations after an attack.

Cybersecurity is a rapidly growing, high-priority area for business investments. For example, GMI Research estimates that Vietnam Cybersecurity Market will be USD 912 million by 2032. This figure exemplifies the growing need for organizations to invest in advanced security measures to protect systems with the increase in cyber threats.

Conclusion

For organizations operating in a digitized world, the necessity of having cybersecurity in place to counter existing and evolving threats cannot be overstated. Knowing the various dimensions of cybersecurity and the threats they protect against is the first step to building a more robust system that provides an additional layer of protection that businesses can trust.
