Essentially, cybersecurity involves taking action to prevent the occurrence of cybercrime, which refers to criminal activities carried out in cyberspace.
For those involved in business, conducting research on cybersecurity is crucial as it can help minimize the risk of cybercriminals stealing and misusing company data.
So, what exactly is cybersecurity, and how should it be implemented? Discover the explanation by reading this article in its entirety.
What is Cybersecurity?
Cybersecurity encompasses security tools, policies, concepts, and more that can be utilized to safeguard organizations and user assets.
It protects organizational and user assets, including computing devices, applications, services, and information transmitted and/or stored in a networked environment.
Implementing cybersecurity measures can reduce the risks posed by threats targeting computer systems.
Concept of Cybersecurity
Cybersecurity refers to the activities aimed at ensuring the confidentiality, integrity, and availability of information. These three aspects are collectively known as the CIA Triad.
The CIA Triad is a security model designed to help individuals comprehend the various components of information technology security. This model serves as the foundation of cybersecurity concepts.
Confidentiality entails efforts to keep data private and secure. It involves controlling access to data in order to prevent theft or unauthorized disclosure.
One way to achieve this is by restricting access to authorized personnel only. For example, only payroll employees should have access to the company’s payroll database, while other employees can only view the company structure, which includes names and job titles.
Privacy can also be ensured through two-factor authentication (2FA). By enabling 2FA, users must complete two authentication steps before gaining access to data. The first step involves a password, while the second step requires a unique code sent to a designated device.
For instance, suppose hackers manage to obtain your website username and password. If you have 2FA enabled, they still won’t be able to log in. Why? Because they don’t have the necessary unique code.
Integrity, in the field of information technology, involves maintaining consistent, accurate, and reliable data.
For instance, if you run an online business store, it is essential to provide clear product information and accurate prices. This allows your customers to trust the integrity of your online store.
Similarly, it is crucial to securely store customer data to prevent data breaches that could impact your customers.
Some methods to maintain data integrity include encryption, digital signatures, and digital certificate authorities (CAs). Certificate authorities such as SSL/TLS are useful for verifying the identity of website users.
The final component of the CIA Triad, availability, refers to the accessibility of your data. In business, it is imperative to ensure that systems, applications, and data are readily accessible to customers.
For example, mobile banking users rely on instant transfers. They would be highly frustrated if the application suddenly crashes, which can erode trust in the bank in question.
Elements of Cybersecurity
There are several elements that make up cybersecurity. Some of these elements include:
1. Application Security
Application security focuses on enhancing the security features of applications to prevent threats from occurring. It protects websites and web applications from various types of cyberattacks that exploit vulnerabilities in the source code.
Common threats that target software or applications include input validation, authorization, session management, and encryption. Measures that can be taken to prevent them include:
- Authentication: Implementing two-factor authentication by sending a code to the user’s mobile phone.
- Authorization: Verifying the user’s authorization level to use the application.
- Encryption: Protecting sensitive user data from hackers.
- Logging: Recording system activities and information.
- Security testing: Checking the effectiveness of the in-app security system.
2. Information Security
Information security refers to the processes and methods used to prevent unauthorized access, use, interference, modification, or destruction of information. This includes protecting personal information, social media profiles, login credentials, emails, network details, bank account data, and more.
3. Network Security
Network security is an element that prevents and protects against unauthorized access to computer networks. It involves configuring measures to prevent and monitor misuse and modification of network and computer resources. Network security includes both hardware and software technologies.
Some methods to enhance network security include:
- Virtual Private Networks (VPNs)
- Network Access Control (NAC)
- Antivirus Software
- Email security
- Web security
- Wireless security
- Endpoint security
4. Disaster Recovery Planning
Disaster recovery planning involves preparing for and recovering from various disasters, including natural disasters and cyber threats. It involves creating a formal document that contains information about administration, financial budget, resources and technology, hardware, and operational security.
5. Operational Security
Operational or procedural security is an element of risk management that protects vulnerable data. It identifies critical information and develops protection mechanisms to ensure its security.
6. Cloud Security
Cloud security aims to protect the security of data stored in the cloud. Threats can come in the form of service traffic hijacking, abuse, and data theft. Implementing cloud security measures is crucial for cloud service providers to protect sensitive customer data and comply with security requirements.
7. End-User Education
End-user education is a vital element of cybersecurity. Lack of cybersecurity education and awareness among end users poses significant risks to individuals and organizations.
Many security vulnerabilities arise from a lack of awareness and insufficient policies, procedures, and protocols. Common areas of vulnerability include text messages, email usage, social media use, application downloads, and password creation and usage.
Types of Cybersecurity Threats
In the field of cybersecurity, various types of threats may arise. Some common types of cybersecurity threats include:
Cybercrime refers to crimes that target computer systems. Cybercriminals engage in illegal activities such as unauthorized access, data manipulation, and disruption, often for financial gain.
Unlike cybercrime, which can target anyone, cyberattacks are often motivated by political gain. These attacks aim to gather information, steal data, or gain control over targeted systems.
Cyberterrorism involves attempts to intimidate, incite fear, or cause panic through computer systems. This type of cyber activity is particularly dangerous as it can create widespread panic and fear.
Cybersecurity Threat Methods
In the application of cybersecurity, various types of threats may arise. Let’s explore some common methods of cybersecurity threats:
The first type of threat is malware, which often takes the form of harmful software that can cause harm to computer users. Malware can spread computer viruses, spyware, worms, and more, posing risks to both computers and their users.
Another cybersecurity threat is ransomware, which is a more extreme form of malware. Hackers typically block access to computers or important documents, demanding a ransom to regain access. However, paying the ransom does not guarantee the return to normalcy for hijacked files or computer systems.
3. Social Engineering
Social engineering is a term used to describe attacks based on human interaction. It manipulates users into providing sensitive information such as passwords and answers to security questions.
These threats often exploit people’s curiosity and trick them into engaging in seemingly normal activities that are, in fact, highly dangerous.
Phishing is a prevalent form of fraud that primarily occurs via email. Scammers send emails using addresses similar to those of trusted sources, with minor alterations that may go unnoticed. These scams aim to steal sensitive data like credit card security (CVC) numbers, passwords, and other important information.
To avoid falling victim to phishing attacks, always double-check the reputation of the email sender when asked to provide sensitive data.
5. SQL Injection
SQL (Structured Query Language) injection is a type of cyberthreat that involves capturing and stealing data from data centers. Cybercriminals exploit vulnerabilities in data-driven applications to inject malicious code into databases using SQL statements, thus gaining access to sensitive information stored in the data centers.
6. Man-in-the-Middle Attack
A man-in-the-middle attack intercepts communications between two individuals with the intention of stealing data. For example, on an unsecured Wi-Fi network, an attacker can intercept data transmitted from the victim’s device and network.
7. Denial-of-Service Attacks
Denial-of-service attacks executed by cybercriminals aim to prevent computer systems from responding to legitimate access requests. This is achieved by flooding the network and servers with bogus traffic, rendering the system unable to function properly.
How to Overcome Cybercrime Attacks
