What is Cybersecurity
Electronic devices, networks, and sensitive data are protected by cybersecurity against unauthorized access, theft, damage and other criminal activity. Various technologies, procedures and practices protect digital information’s privacy, availability, and integrity.
The growing use of technology and the internet has made it simpler for hackers and other crooks to access sensitive data, making cybersecurity important. It may result in severe financial losses, harm one’s reputation, and potentially have legal repercussions for individuals and businesses. Some basic cybersecurity strategies are using secure passwords, installing firewalls and antivirus software, keeping software and systems up to date, and training staff to spot and prevent common cyber threats.

Types of Cybersecurity
There are several types of cybersecurity, each focusing on a specific protection and security area. The most common types are explained below.
Network Security
Network security defends computer networks from unauthorized entry, use, theft or damage to their hardware, software or data. It involves implementing various measures and technologies to secure network infrastructure, data, and communications against attacks, threats, and vulnerabilities. There are several types of network security measures as follow:
- Access control
This refers to controlling who can access the network and their access level. - Firewalls
They are hardware or software systems that observe and filter incoming and outgoing network traffic & blocking unauthorized access. - Encryption
It converts data into an indistinct form that can only be translated using a secret key or password. - Intrusion detection and prevention
These systems monitor network traffic for suspicious activity and can prevent or mitigate attacks. - Virtual private networks (VPNs)
A VPN creates a protected and encrypted link between two devices over the internet & allowing remote access to network resources. - Anti-virus and anti-malware software
These programs catch and remove negative software such as viruses, adware and spyware from network devices.
Application Security

FAQ’s
Is cybersecurity hard?
Yes, cybersecurity is challenging. It requires a deep understanding of complex systems and technologies and thinking like a hacker to anticipate and prevent attacks. It also demands constant vigilance and adaptation to evolving threats. It is a challenging but essential field critical in protecting digital assets and safeguarding sensitive information.
How long does it take to get a cybersecurity degree?
The degree level and the programme’s design are two variables that influence how long it takes to earn a cybersecurity degree. An average cybersecurity bachelor’s degree could take four years and a master’s degree could take further two years. But additional colleges offer accelerated courses that can be completed in as small as two to three years. Furthermore, online or part-time programmes may take longer to complete than regular full-time ones. The time required to achieve a cybersecurity degree eventually depends on the student’s unique situation and the programme’s requirements.
What are the 5 laws of cybersecurity?
Principle of least privilege: Users and techniques should only have access to the details and resources required to complete their tasks.
Defense in depth: Multiple layers of security controls should be implemented to protect against attacks from various vectors.
Patching and updating: Regular updates and patches should be applied to software and systems to address known vulnerabilities.
Continuous monitoring: Ongoing monitoring and analyzing network traffic and system logs can detect and prevent cyber-attacks.
Incident response: Organizations should have a plan to quickly and effectively respond to security incidents to minimize damage and ensure business continuity.
How to measure anything in cybersecurity risk?
Quantitative analysis: involves assigning a numerical value to the likelihood and impact of potential risks. It can be done using statistical models or simulations to estimate a cyber attack’s probability and potential damage.
Qualitative analysis: This involves using expert judgment and subjective criteria to assess the severity and likelihood of potential risks. It can be done through workshops or surveys to gather input from stakeholders.
Risk scoring: involves assigning a score to each risk based on its likelihood and impact. It can be done using a standardized risk assessment framework, such as NIST Cybersecurity Framework or ISO/IEC 27001.
Red team testing: This involves simulating a cyber attack to identify vulnerabilities and assess the potential impact of an attack. It can be used to validate and improve risk assessments.
What is a network security key?
A sequence of letters and numbers called a network security key, Wi-Fi password or network passphrase is used to establish and encrypt transmission between devices on a wireless network. It is a type of network security that needs a password to join the network, preventing illegal access and data theft. The network administrator creates the security key that authorized users must enter to access the network.
How to find network security key?
You can use a third-party programme to look up Wi-Fi passwords by checking the router’s label or web interface, checking the device settings for a connected device or resetting the router to its manufacturer’s default settings to recover the network protection key. It is important not to share your network protection key with unauthorized users or store it in an easily available location for security reasons.
What is Application Security testing?
Application security testing is the method of determining and managing security vulnerabilities in software applications. It involves testing the application for weaknesses that attackers could exploit such as injection attacks, cross-site scripting and authentication issues. Application security testing is typically performed using automated tools and manual testing techniques.
What is Web Application Security?
Web application security protects web applications from various cyber attacks that can compromise their confidentiality, integrity or availability. It includes selecting and managing vulnerabilities in web applications such as SQL injection, cross-site scripting and cross-site demand imitation. Web application security is crucial for organizations relying on web applications to conduct business operations.
Information Security Analyst?
