Firewall
It refers to network security devices that help to monitor and control the network traffic. It acts as a defender between the trusted and untrusted external network, which allows the data packets to be blocked based on predefined security rules.
Phishing
This kind of cyberattack method is used by the attackers and employs deceptive messages, emails, or websites to make the individuals reveal sensitive data such as financial data or login credentials.
DDoS Attacks
Distributed Denial of Service (DDoS) attacks make the target system or network to be flooded with traffic and thus the user cannot to be able to access those services. To execute this kind of attack, the attackers use the compromised network such as botnets.
Vulnerability
Vulnerability refers to weaknesses in the system, application, and data that are exploited mainly by hackers with the intention of compromising network security. To nullify this kind of attack, we have to identify and patch the vulnerabilities that exist in the network.
Bots
A bot represents an application or script specifically created for executing repetitive and automated functions. While certain bots serve legitimate functions, such as chatbots designed to respond to frequently asked questions on websites, others are employed for malicious intent. These bots engage in activities like distributing spam emails or orchestrating Distributed Denial of Service (DDoS) attacks.
With the increased usage of bots, distinguishing between benign and harmful ones, or even bots from human users becomes increasingly challenging. This growing complexity underscores the escalating threat that bots pose to both individuals and organizations.
Digital Certificate
A digital certificate, also referred to as an identity certificate or public key certificate, serves as a secure key for facilitating data exchanges over the Internet. Think of it as a digital file securely embedded in a device or hardware component. Its primary function is to authenticate the device or server during the transmission of data. In essence, this certificate ensures that data sent and received between two devices or a device and a server remains confidential and secure.

Password Cracking
Password cracking involves the process of attempting to guess or forcibly break a password in order to gain unauthorized access to a system or account.
Ransomware
This is a form of malicious software (malware) that locks a victim’s files or data behind encryption and then demands a ransom payment in exchange for providing the decryption key.
Protective Measures
Antivirus Software
Antivirus software helps to detect, defend, and destroy malware from computers and networks. The software will be involved in scanning malicious code and patterns to retain the system in secured mode.
Multi-Factor Authentication (MFA)
Multi-factor authentication MFA brings an additional layer of security by holding the user’s multiple identities and it requires multiple forms of identification for granting access. Some of the Multi-factor authentication identities such as passwords, tokens, and biometrics.
Patch Management
Patch management involves the process of updating the systems and software in a regular manner to identify vulnerabilities. If the patching process is not carried out in a periodic manner, the system will be exposed to harmful attacks and cyber threats.
Network Segmentation
Network segmentation partitions the network into smaller and isolated segments to restrict breaches and harden the network security to defend against the attacks exploited by intruders.
Incident Response Plan
The incident response plan includes the aligned procedures for detecting, managing, and defending security incidents. To minimize the damage that occurs during the cyberattack, a well-defined incident response plan is required.
VPN (Virtual Private Network)
A VPN is a secure connection established between devices over the internet. It effectively shields all data transmitted between these devices by encrypting it, ensuring confidentiality and security.
Types of Cybersecurity
Application Security (AppSec)
Application security, often referred to as AppSec, involves the practice of integrating and testing security measures within web applications. Its purpose is to shield these applications from potential threats. Vulnerabilities, security misconfigurations, and design flaws can be exploited, leading to issues such as malicious code injections, exposure of sensitive data, system compromise, and other harmful consequences.
Notably, AppSec holds significant importance as the application layer is particularly susceptible to breaches.
Cloud Security
Cloud security is a relatively recent addition to the cybersecurity landscape. It revolves around safeguarding cloud computing environments, applications, and data stored in the cloud. While cloud providers implement their own security measures, clients also have a shared responsibility for configuring and using their cloud services securely.
Critical Infrastructure Security
Critical infrastructure security safeguards the essential infrastructure elements of a region or nation. This encompasses both physical and digital security, systems, and assets that contribute to physical security, economic stability, public health, and safety.
Examples include the electricity grid, hospitals, traffic management systems, and water supply networks. Given the digital nature of critical infrastructure, it is vulnerable to cyberattacks and requires robust protection.
Internet of Things (IoT) Security
IoT security focuses on securing an expansive array of internet-connected devices that can communicate independently. This category includes devices like baby monitors, printers, security cameras, and motion sensors.
Many of these devices collect and store personal information, making them attractive targets for malicious actors seeking to steal identities. Therefore, robust security measures are necessary to protect against unauthorized access and other potential threats.
Network Security
Network security is the practice of defending computer networks and data against threats, both external and internal. This involves implementing identity and access controls, such as firewalls, virtual private networks (VPNs), and two-factor authentication (2FA). Network security typically comprises three main categories: physical, technical, and administrative, all of which aim to ensure that only authorized individuals have access to network components, data, and the network infrastructure itself.
Each of these cybersecurity domains plays a crucial role in safeguarding digital assets and ensuring the integrity, confidentiality, and availability of data and systems.
