Insight into Cyber Security: A Brief Overview

There is no sign that the world’s reliance on technology will lessen in the near future. From nearly instantaneous Internet information access to the modern comforts provided by automation technology and concepts like the Internet of Things, this phenomenon has many benefits.

It can be tough to comprehend that potential dangers hide behind every technology and network when the internet has brought so much good. Nonetheless, despite how favorable the current advancements are, cyber security concerns presented by advanced technologies pose a major concern.

The perpetual rise in cybercrime highlights the vulnerabilities in the technology and internet that we’ve become so dependent on. That is why the importance of cyber security has risen equivalently.

What is Cyber Security?

Cybersecurity is the defensive technique against cyber threats for systems connected to the internet, including their hardware, software, and data. Individuals and businesses both utilize this approach to prevent illegal access to data centers and other digital systems. Cybersecurity refers to the safeguarding of sensitive information and critical systems against online threats. Cyber security systems are also referred to as information technology (IT) security. Cyber security works in a way to counter attacks on networked systems and applications, regardless of whether those threats come from within or outside of an organization.

A robust cybersecurity system can offer a good security stance against malicious attempts and cyber attacks. The motive behind the cyber attacks and threats can be to gain access to, modify, delete, corrupt, destroy, or extort sensitive IT data and systems. These data and systems may belong to a business or individual. Cyber security measures are essential in preventing cyber attacks that try to disrupt or impair a system or device’s functionality.

What Makes Cyber Security so Important?

The value of cybersecurity is expanding. Fundamentally, there is no sign that the role of technology in our economy or society as a whole will decrease. Identity theft-related information breaches have become more common now. Everyone now uses cloud storage solutions like Google Drive or Dropbox to store personal and sensitive data.

The truth is that everyone uses internet networks on a routine basis, whether they’re individuals, local firms, small businesses, or giant multinationals. We now have a broad range of possible security vulnerabilities that weren’t present a few years ago. It also accentuates when we combine this with the surge in cloud services, smartphones, lax cloud service security, and the Internet of Things (IoT). Therefore, ignoring the importance of cyber security can result in substantial damage.

Antivirus software and firewalls are no longer effective and adequate at preventing cyber threats. The possibility of cyberattacks is indeed rising, and for companies and organizations, the concern is no longer “if” but instead “when.” Due to this, cyber security is very crucial.

The importance of cybersecurity is only going to increase with an influx of more data, most of it confidential or sensitive. The problem is accentuated by the rise in the number of cyberattackers and attack techniques, as well as their complexity.

Cyber Security Domains

A robust and comprehensive cyber security system includes many layers of defense to avoid and tackle cyber threats at various levels of an organization’s IT infrastructure. In light of the fact that an organization’s IT assets include a variety of multiple platforms and channels, an effective cyber security architecture is a must to synchronize operations across all of its systems. As a result, the following sub-domains fall under cyber security:

Application Security

Application security is the implementation of multiple defenses into all software and services deployed within an organization. This is to safeguard them against a broad range of threats. It is crucial to create secure application architectures, produce cryptographic protocols, implement rigorous data input validation, execute threat modeling, and other actions. The goal is to decrease the probability of any unauthorized access and modification of IT and software application resources

Data Security and Identity Management

The frameworks, workflows, procedures, and operations involved in identity management allow only authorized users to access information systems inside an organization. Data security encompasses the application of reliable information storage solutions that ensure data security both at rest and in transit.

Network Security

This encapsulates a broader security domain that includes the use of both hardware and software solutions to safeguard the IT infrastructure and network from unauthorized access, breaches, malfunctions, and abuse. The assets of an organization must be protected from both internal and external threats, which is why network security is crucial.

Mobile Security

Mobile security pertains to protecting against threats like illegal access, device theft or loss, virus, ransomware, etc., for both organizational and personal data stored on mobile devices.

Cloud Security

For companies using AWS, Google, Azure, Rackspace, and other cloud service providers, cloud security refers to the development of secure cloud systems and applications. A well-designed ecosystem and setup confirm protection from a wide range of threats.

Disaster recovery and Business Continuity

Processes, surveillance, alert notifications, and plans that assist organizations in preparing for maintaining business critical systems online during and following an accident, in addition to resuming and restarting lost operations and systems, are referred to as disaster recovery and business continuity planning.

When a cybersecurity incident occurs or another event results in the loss of operations or data, an organization’s response makes up the disaster recovery and business continuity strategy. Disaster recovery procedures specify how the company restores its activities and data to resume normal operations in the same manner as before the incident. The organization’s backup plan, which it uses when operating without specific resources, is called business continuity.

User Education

Each and every member of an organization must be aware of cyber threats. It is crucial to provide business staff with training in the fundamentals of cybersecurity in order to increase awareness of organizational procedures, internal structure, working policies, and industry best practices, as well as to observe and report suspicious, fraudulent, or malicious activity. Cybersecurity-related seminars, training programs, and certifications are covered by this subdomain.

Common Cyber Threats to Manage

Cybersecurity experts put a lot of effort into reducing security breaches, but attackers are constantly seeking new ways to avoid detection by IT, get around defenses, and take advantage of flaws that are appearing. New cloud services, work-from-home scenarios, remote access technologies, and cybersecurity threats are being used by the most recent cyberattacks to repurpose “known” vulnerabilities.

The following are some of the most typical cyber threats:


Despite a steady drop over the past couple of years, the malware remains among the most prevalent types of cybersecurity risks. It is basically “malicious software,” a broad category that encompasses programs and several lines of code that corrupts the program or grants unauthorized access.

Malicious software versions, such as viruses, worms, Trojan horses, and spyware, that enable illegal access or impair a computer are referred to as “malware.” Deploying this malware can be as easy as installing unwanted pop-up windows on a computer or as dangerous as collecting personal information and transmitting it somewhere else. These days malware attacks are becoming more “fileless.” Furthermore, the structure of this malware is such that it can easily steer clear of common detection systems. These may include antivirus software that scans for malicious files.


Ransomware is a type of virus that encrypts data, files, or systems and keeps them as hostages. Cybercriminals who attack the systems through these kinds of viruses then demand a ransom payment. They ask for ransom in order to unlock and decrypt the hostage files. Failing to pay the ransom may force cybercriminals to delete, damage, or publicly release the data. Paying the ransom does not, however, ensure that the system will be restored or that the files will be recovered.

Phishing/Social engineering

Users are tricked into disclosing their own personal information or confidential details through the practice of phishing, which is basically a type of social engineering. In phishing scams, emails or text messages are sent that seem to be from a reliable company seeking private information. Such phishing emails demand login credentials, bank details, or credit card details. The rise of remote employment has been linked to an increase in pandemic-related phishing.

The most prevalent type of cybercrime is phishing. You can better protect yourself by getting educated or by using a technological tool that screens malicious communications.

Insider Threats

Anyone who has had access to a company’s networks or systems in the past might be regarded as an insider threat if they misuse their access privileges. This can include the organization’s current or former employees, business associates, partners, contractors, or other individuals. Most of the conventional cyber security measures like firewalls and intrusion detection technologies target external threats. Henceforth, they may not be capable of recognizing insider threats.

Distributed denial-of-service (DDoS) Attacks

A DDoS attack attempts to shut down a server, website, or entire network system. They do so by overloading it with traffic, frequently from many synchronized systems. DDoS attacks inrush enterprise networks by using the simple network management protocol (SNMP), which modems, printers, switches, routers, servers, and other IT infrastructure resources use.

Advanced Persistent Threats (APTs)

An APT is when a hacker or group of hackers infiltrates an IT system or network and goes unnoticed for a long time. In order to snoop on corporate activity and collect sensitive data without triggering off defensive counter mechanisms, the hacker leaves the networks and systems untouched.

Man-in-the-middle Attacks

An eavesdropping tactic known as “man-in-the-middle” involves a cybercriminal intercepting and transmitting data/critical information between two entities in order to steal data. An attacker may, for example, collect data passing between a visitor’s device and an unsafe Wi-Fi network.

Implementing Cybersecurity: A Brief Guide

The implementation of robust cybersecurity can be difficult since the cyber threat landscape is always changing. However, it’s not unrealistic if businesses embrace a systematic technique that includes the following components:

Risk Assessment and Management

A risk-based approach implies and ensures that cyber security professionals are aware of the most significant cyber threats to the company. Certainly, this also makes sure that they are capable of taking the needed actions to mitigate their potential impact.

Manage Asset Inventories

Understanding enterprise assets is essential for identifying any threats to those assets and addressing them.

Determine and Fix the Vulnerabilities

In particular, if a vulnerability is critical and has the potential to seriously impact any organization or its operations, the concerned organization should identify and resolve it as immediately as possible.

Set Up Identity and Access Management Solutions

Access to services, systems, and data must be protected. Indeed, this must be in complete control in order to avoid cyberattacks from both insiders and outsiders.

Data Security

Safeguard all confidential and sensitive corporate data and files from unauthorized access or use.

Incident Management

Effective and well-built incident management reduces the overall impact and harm that security incidents can cause to the networks and IT infrastructures.

Supply Chain Security

Detecting, identifying, and continuously addressing the risks and vulnerabilities of third-party systems and networks is equally essential.

Workforce Training and Education

Many research studies show that human error is a major factor in many security breaches and cyberattacks. Employees commonly make the blunders of creating weak passwords or succumbing to phishing attempts. Furthermore, they sometimes neglect to update their devices’ software security applications. A successful cybersecurity plan entails rigorous training of employees in proper cybersecurity practices. Indeed, it also ensures that they follow all the cyber security protocols.

The Emergence of AI in Cyber Security

Artificial intelligence (AI) is assisting under-resourced security operations analysts in keeping ahead of threats as cyberattacks increase in volume and complexity. Using AI technologies like machine learning and natural language processing reduces the response times substantially. In fact, this also offers quick insights to cut through the cacophony of everyday alerts.


In the connected world of today, cutting-edge cyber security measures are a must for every individual as well as organization. A cybersecurity intrusion can ultimately lead to anything from data theft, identity theft. Further, this can also lead to fraud, extortion threats, and loss of sensitive information.

Every day, cyber threats can affect both big and small businesses. Companies frequently fail to adopt cyber security measures until it is much too late. This is because they are unaware of the myriad of cyber threats that exist within their IT infrastructure.

Specialists in cyber security can be quite helpful in defending against cyber predators and cyber threats. They continually look into potential cyber risks and devise cyber security tactics. Indeed, they strengthen open source tools, unveil unidentified flaws, and create awareness about the value of cybersecurity.
