Table of Contents

As per the Cambridge Dictionary, “Cybersecurity is the things which are done to protect a person, organisation, or country and their computer information against crime or attacks carried out using the internet.” This includes defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. Cybersecurity comprises security on the network, application, information, operational, disaster recovery and business continuity. 

The primary object of cybersecurity is to ensure the confidentiality, integrity and availability of information and resources in the digital world. Confidentiality means protecting data from unauthorised access, integrity means safeguarding the accuracy of the data, and availability means ensuring that digital systems and data are constantly accessible when needed.

Cybersecurity also encompasses various security strategies, practices and technologies to achieve its objectives. These include antivirus software, firewalls, encryption, access controls, Intrusion Detection Systems (IDS), Intrusion Prevention Systems (IPS), encryption, security audits, security compliance, security awareness training, incident response, Multi-Factor Authentication (MFA), etc.

The Need for Strong Cyber Security Architecture

In our ever-evolving interconnected world, we never know what might happen next. We cannot predict when hackers or cyber attackers will find a vulnerability in our computer systems and exploit them. That is why a robust cybersecurity framework should be implemented to reduce the risk of cybersecurity breaches. Gone are those days when cyberattacks were less frequent and less complex and also when the approach to cyber security was not as complicated.

This modern era has brought in complex security threats and sophisticated attackers. So, to stay one step ahead, organisations must adopt a consolidated cybersecurity strategy that offers deeper visibility and more robust defences. Another thing that adds a layer to an already complex digital realm is the increase of cloud environments. The network is sprawling, and it makes it hard to maintain a robust cybersecurity posture all around the organisation.

As technology evolves and “bring your own device” (BYOD) policies become the norm, securing a diverse range of devices, some not even owned by the company, becomes imperative. Additionally, the rise of remote work, exemplified by the response to the COVID-19 pandemic, has reinforced the need for robust cyber security solutions and infrastructure security to protect remote and on-site employees from cyber attacks.

So, to tackle the security risks in today’s complex digital world, organisations need to keep things simple and effective. They must realise that consolidating and streamlining their security programs is the most scalable and sustainable way to manage security risks, threats and vulnerabilities. It’s like building a strong, reliable security fortress to protect against all the potential dangers out there. By doing this, they can ensure good security that stands the test of time and adapts to the ever-changing digital landscape.

Different Types of Cyber Security

Cybersecurity can be divided into a few categories. They are:

Network security is focused on safeguarding the integrity and privacy of data transmitted across networks. It involves measures such as firewalls, intrusion detection systems, and encryption to shield against cyber threats.

Information Security protects sensitive information from unauthorised access, disclosure, or modification and encompasses data classification, access control, and encryption.
Application Security aims to identify and rectify vulnerabilities within software applications to prevent exploitation by malicious actors and involves secure coding practices and regular testing.
Endpoint Security concentrates on safeguarding individual devices like computers and mobile devices. It includes antivirus software, firewalls, and intrusion prevention systems to fortify these entry points.
Cloud Security involves securing cloud-based infrastructure and sensitive data through encryption, access controls, and compliance monitoring.
Data Security is the protection of data at rest or in transit from data breaches, and it encompasses encryption, data loss prevention, and secure data storage practices.
Internet of Things (IoT) Security protects internet-connected devices and networks, ensuring they are resistant to cyber threats.
Mobile Security includes measures to protect mobile apps, data, and the devices themselves from threats like malware and data breaches.

Different Types of Cybersecurity Threats

Hacking is when someone with technical skills gains unauthorised access to computer systems or networks, often to steal or manipulate information.

Malware is software designed to sneak into your computer and disrupt things. There are different types of malware, like viruses, worms, or spyware.
Ransomware is malware software that makes your computer files closed or unable to open unless you pay for them. 
Identity Theft means that a cybercriminal gains access to your personal information,  like your social security number or credit card details, to pretend to be you and steal money or gain other benefits. 
Phishing occurs when cybercriminals send deceptive emails or set up fake websites to trick you into sharing your personal information, like passwords or credit card numbers.
Online Scams are done by real-looking companies who work to get bank details and access them for withdrawal or transfer. 
Data Spill occurs when sensitive information is accidentally or intentionally exposed to the public.
Distributed Denial of Service (DDoS) attacks flood a website with so much traffic that it cannot handle it, making it unavailable to regular users.

Insider threat is a security risk originating from individuals within an organisation, whether intentional or unintentional, that can compromise data and system integrity.

Social engineering is a deceptive and manipulative technique cybercriminals use to trick individuals into revealing sensitive information or taking specific actions. It often involves impersonation, persuasion, or psychological manipulation to achieve malicious goals.

How To Stay Safe from Cyber Threats?

To stay safe and secure online, you should at least follow the major preventive measures against cybercrimes or cybercriminals. Here are some major and straightforward steps you can take to ensure your cybersecurity. 

Strong Passwords: Use strong, unique passwords that combine numbers, symbols, and upper and lower-case letters for your online accounts.

Multi-Factor Authentication (MFA): Enable MFA wherever possible, as this reduces cyber risks. This adds an extra layer of security by requiring multiple forms of identification, like a password and a code sent to your phone.

Update Software: Regularly update your operating system, software, and antivirus programs. Updates often include patches for known security vulnerabilities.

Beware of Phishing: Be cautious about clicking links or downloading attachments from unfamiliar or suspicious sources. Phishing emails often trick you into revealing personal information.

Firewall: Enable your device’s firewall to block unwanted access to your computer or network.

Backup Data: You should regularly back up your important data so that in case of a cyberattack or hardware failure, you won’t lose valuable information.

Employee Training: If you’re a business owner, ensure your employees are trained in cybersecurity best practices to prevent data breaches and protect sensitive company information.

Regular Audits: Conduct security audits and assessments to identify and address system vulnerabilities to prevent cyber security risks.

Incident Response Plan: You should develop and implement an incident response plan that outlines the steps to take in case of a cyber security incident. This can help minimise damage and downtime.
