If you want to keep intruders away from your home, what precaution will you take in the first place?
The simplest answer is locking your doors and gate.
Right?
The Cyber world is just like a home, and to keep it safe from ‘cyber-intruders’, we all need a robust safety lock, cybersecurity.
Cybersecurity helps your online world stay secure from unwanted people by ensuring your important information stays safe, confidential, and available only to the reliable and right people.
When someone with wrong and harmful intentions tries to breach this security, it’s called cyber-attacking, and the person is named a hacker.
Cyber attacks in the internet world are so normal and happen every day globally. With no basic protection, any individual or company can become a victim in the cyber world.
Therefore understanding about cyber security, even a little, is as crucial as locking your home.
Let’s understand further more about cyber security in terms of digital and technical outlook.
Cybersecurity is the compulsory practice of securing sensitive data, internet networks, and all digital devices from potential cyber threats. Here, cyber threats mean hacking, malware, and phishing attacks. It is also referred to as Information Assurance (IA), System Security, and Information Security (INFOSEC).
Cybersecurity offers a vast range of efficient strategies, modern technologies, and best practices designed and developed to protect computers, networks, and confidential data from hackers. It includes utilizing specialized tools to detect harmful software first and then remove it properly, while identifying and avoiding online scams simultaneously.
In 1972, the internet was just beginning its journey and was called ARPANET back then. An experiment was done by experts. In this experiment, a program as a test virus was created, named ‘Creeper’. Then another software called ‘Reaper’ was designed to remove ‘Creeper’. This early experiment clearly defined why digital security was compulsory and led initiate what we now name Cyber security.
Cybersecurity is so crucial for governments, corporations and other organizations. Because these institutions and authorities collect military, financial, and developmental inputs, then process and store these unprecedented amounts of confidential data on a computer (server) along with other personal information.
Without proper cybersecurity protection, these information exposures could have serious negative consequences. At this stage, cybersecurity is compulsory now for every government, authority, organization, and institution, including individuals, working in the cyber world.
Cybercrimes and Cyberattacks can harm and damage, destroy, and ruin businesses, communities, institutions, and even human lives. Breached security incidents often cause identity theft, extortion and the loss of personal sensitive information. These consequences affect the businesses and economies significantly.
Here is an estimate by experts: cybercrime will cost the global economy approximately USD 11 trillion per year by 2025-2026. The cost of cyber attacks is also increasing rapidly every year.
The latest cost of a ‘Data Breach Report’ (DBR) in 3 points:
Average Loss/Cost: The average cost of data breached in 2023 was, USD 4.45 million, which jumped to USD 4.88 million in 2024. A considerable 10% spike and the highest raise documented since the pandemic.
Losses on Businesses: Business losses and after breach response cost increased almost 11% over the last year. A single data breach averages USD 1.38 million of lost business in 2025. This figure includes lost clients, reputational damage and costs related with system downtime.
Regulatory Fines: The number of organizations increased 22.7% over the last year, paying more than USD 50,000 in regulatory fines. While companies paying more than USD 100,000 as regulatory fines, increased by 19.5%.
Hackers, the cyber criminals, generally use advanced techniques to steal data, find weaknesses in systems to change the actual data, and break into organizations’ networks without permission.
Here are the top 10 cybersecurity threats and attacks that target businesses, cloud storage and individual devices:
Malware is a harmful program. It is created by hackers and cyber criminals to enter, attack, and compromise computer systems. It includes Trojans, rootkits, and spyware.
Phishing is a technique used by hackers, applying tricks and manipulation to steal confidential information as login details, session tokens, and financial information.
While Spear phishing is a more targeted and advanced version of Phishing. It uses open-source intelligence (OSINT) to establish personalized fake messages.
As name suggests Ransom-ware attack is associated with asking ransom money. It locks important system files of individual or company, by encrypting them using asymmetric cryptography (like RSA, ECC) or hybrid encryption (AES-RSA). Then it demands a ransom, usually in ‘Crypto currency’, to unlock the encrypted files and let use the data as before.
A DDoS attack is one of the most powerful and effective weapons on the cyber platform, used by hackers. A DDoS attack generally uses multiple servers, systems, and internet connections.
These connections are Trojan infected, to overload a network or targeted resource, with massive amounts of traffic at different level, causing servers to crash and making services collapsed.
SQL injection (SQLi) and NO-SQL injection (NO-SQLi) are security vulnerability, occur when a hacker or an attacker inject malicious SQL code into the queries to modify database records, steal login credentials, delete sensitive data or even run admin level command in a weak web application. In many cases, attackers can even gain full control over the database or server.
Zero-day exploits take advantage of unknown software vulnerabilities before developers release security patches, making them highly dangerous.
An advanced Persistent Threat (APT) refers to a long-term and sophisticated attack, using stealthy methods to avoid advanced detection inside organizations for month or years and at the same time continuously stealing confidential and sensitive data.
Man-In-The-Middle (MITM) attacks, as name itself define, secretly intercept the confidential data and modify data exchanged between two parties. Attackers use this technique by exploiting weak encryption protection or unsecured communication channels.
When a compromised or malicious employee with high-level access, steals confidential data or sensitive files, change access permissions, or install a backdoor to outsmart security process, Insider Threats occurs. As these insiders have already access to sensitive data, they misuse this for their own interests.
Cyber-frauds often take help of AI to produce fake emails, applications and other business documents in any minute. Some hackers use open source generative AI and others also use organization’s AI tools as attack vectors.
When cyber-attackers gain access to a computer device and use it to mine crypto-currencies as ‘Bitcoin’ and ‘Ethereum’, that when Crypto-jacking happens. Many security experts and analysts identified crypto-jacking as a cyber-threat in 2011, just after the crypto-currency introduced.
Each and every organization uses its own cyber security methods, which can be way differ in strategies and in executions. But many use some common but advanced tool and tactics to eliminate vulnerabilities, intercept potential cyber-frauds, and prevent cyber-attacks.
These are 6 most commonly used best practices:
Security awareness training and robust data security policies can be a great help for employees to protect their personal and professional data in an organization.
Data security tools offer significant help to stop cyber-security threats or minimize their effects. Data Loss Prevention (DLP) tools can effectively detect and instantly block attempted sensitive data theft.
Identity & Access Management (IAM) defines the tools and strategies that monitor and control how users are accessing digital resources and what they can do with those resources and data.
Attack surface management (ASM) is a continuous process of analysis, discovery, and monitoring of the potential cyber-security vulnerabilities & frauds that can lead cyber-attacks on an organization’s system.
In modern era analytics and AI-driven technologies can be a great help in identifying and responding to potential attacks or cyber-crimes in progress.
These technologies can include Security Information and Event Management (SIEM), Security Orchestration, Automation and Response (SOAR) and Endpoint Detection and Response (EDR).
Disaster recovery capabilities play a remarkable role in the maintenance of business continuity and eliminating or minimizing threats during any cyber-attack.
Encryption is a key part of cyber security. Encryption keeps our sensitive and confidential information private and accessible only to authorized users. Encryption as cyber security is vital for protecting financial transactions, personal messages or information, and corporate data from any misuse or theft. Practicing good cyber security habits helps keep your data private and ensures a safe online experience.
