Cybersecurity is the practice of protecting critical systems and sensitive information from digital attacks. Also known as information technology (IT) security, cybersecurity measures are designed to combat threats against networked systems and applications, whether those threats originate from inside or outside of an organization.
Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative.
A successful cybersecurity approach has multiple layers of protection spread across the computers, networks, programs, or data that one intends to keep safe. In an organisation, the people, processes, and technology must all complement one another to create an effective defence from cyber attacks. A unified threat management system can automate integrations across select Cisco Security products and accelerate key security operations functions: detection, investigation, and remediation.
Cyber security is essentially the application of technologies, processes, and controls to protect systems, networks, programs, devices and data from cyber attacks.
It aims to reduce the risk of cyber attacks and protect against the unauthorised exploitation of systems, networks, and technologies.
Why is cyber security important?

1) The costs of cyber security breaches are rising.
Privacy laws such as the GDPR (General Data Protection Regulation) and DPA (Data Protection Act) 2018 can mean significant fines for organisations that suffer cyber security breaches. There are also non-financial costs to be considered, like reputational damage.
2) Cyber attacks are increasingly sophisticated.
Cyber attacks continue to grow in sophistication, with attackers using an ever-expanding variety of tactics. These include social engineering, malware and ransomware.
3) Cyber security is a critical, board-level issue.
New regulations and reporting requirements make cyber security risk oversight a challenge. The board needs assurance from management that its cyber risk strategies will reduce the risk of attacks and limit financial and operational impacts.
4) Cyber crime is a big problem.
According to The hidden costs of cybercrime, a 2020 study carried out by McAfee and the CSIS (Centre for Strategic and International Studies), based on data collected by Vanson Bourne, the world economy loses more than $1 trillion (approximately £750 billion) each year. Political, ethical, and social incentives can also drive attackers.

Uplatz provides this Cybersecurity course that explains in brief about the world of Cybersecurity. The Cybersecurity course will help you understand the key fundamentals of IT security and the best practices.

1. What is Cryptography?

Cryptography is the practice and study of techniques for securing information and communication mainly to protect the data from third parties that the data is not intended for.


2. What is the difference between IDS and IPS?

IDS is Intrusion Detection System and it only detects intrusions and the administrator has to take care of preventing the intrusion. Whereas, in IPS i.e., Intrusion Prevention System, the system detects the intrusion and also takes actions to prevent the intrusion


3. What is traceroute? Why is it used?

Traceroute is a tool that shows the path of a packet. It lists all the points (mainly routers) that the packet passes through. This is used mostly when the packet is not reaching its destination. Traceroute is used to check where the connection stops or breaks to identify the point of failure.


4. What is a Botnet?

A Botnet is a number of devices connected to the internet where each device has one or more bots running on it. The bots on the devices and malicious scripts used to hack a victim. Botnets can be used to steal data, send spams and execute a DDOS attack.


5. What is a firewall?

A firewall is a system that monitors incoming and outgoing traffic on the network. It analyses all the activities carried out by users on the network and matches it with predefined policies. If there are any violations or deviations from the set policies, the traffic is blocked. It is highly helpful against common cybersecurity threats such as trojans, viruses, malware, etc.


6. What is a VPN?

VPN stands for Virtual Private Network. It is used for data protection against spoofing, censorship, and interference from higher authorities.


7. What are DDoS attacks?

DDoS is an abbreviation for Distributed Denial of Service. It makes servers unavailable when they are occupied and cannot be handled.

A DDoS attack attempts to disrupt normal traffic of the target server or network by overloading it with Internet traffic.

DDoS attacks can be further classified into flooding attacks and crash attacks.


8. What do you understand by phishing?

Phishing is a type of attack which is often used to steal private data and credentials.

It uses fraudulent emails or messages which lead unsuspecting people to click on malicious URLs and fake websites in disguise.

Phishing can have dangerous results like malware being installed on a system, ransomware attacks, stealing money, exposing sensitive information, identity theft, etc.


9. How does the ransomware function?

Ransomware is used to launch malicious attacks on systems, hold them “hostage” and extort money and/or information.

It encrypts the target system’s data, making it inaccessible or corrupt.

Attackers can then demand a ransom amount from the victim in exchange for the decryption key for the unreadable data and restoring access.


10. Define Botnet. Is It Crucial in Cybersecurity?

A botnet is a sophisticated, centrally coordinated malware-infected network controlled by a remote attacker. Each controlled device within this network is considered a bot. Large-scale botnets can consist of millions of bots, enabling cybercriminals to launch massive attacks. Botnets are capable of executing distributed denial-of-service attacks (DDoS attacks), brute force attacks, and more. The term “botnet” is shorthand for “robot network.” Because botnets can cause extensive damage, combating these types of attacks is crucial in the field of cybersecurity


11. What Is SSL Encryption?

SSL (Secure Sockets Layer) encryption serves to create a secure internet connection. SSL encryption protects client-client, server-server, and client-server connections, circumventing unauthorized parties from monitoring or tampering with data transmitted online. An updated protocol called TLS (Transport Layer Security) encryption has replaced SSL encryption as the standard security certificate.


12. What Is Forward Secrecy?

Forward secrecy is a feature of certain key agreement protocols that generates a unique session key for each transaction. Thanks to forward secrecy, an intruder cannot access data from more than one communication between a client and a server—even if the security of one communication is compromised.  


13. What Are Spyware Attacks?

Spyware is a kind of malware that is covertly installed on a targeted device to collect private data. Spyware can infiltrate a device when a user visits a malicious website, opens an infected file attachment, or installs a program or application containing spyware. Once installed, the spyware monitors activity and captures sensitive data, later relaying this information back to third-party entities. 


14. What is the main objective of cyber security?


Cybersecurity aims to protect the computers, networks, and software programs from such cyber attacks. Most of these digital attacks are aimed at accessing, altering, or deleting sensitive information; extorting money from victims; or interrupting normal business operations


15. Where is cyber security used?


Cybersecurity is the protection of internet-connected systems such as hardware, software and data from cyberthreats. The practice is used by individuals and enterprises to protect against unauthorized access to data centers and other computerized systems.


16. What are the 7 types of cyber security?


Malware. Malware is malicious software such as spyware, ransomware, viruses and worms. 


Denial of Service. 

Man in the Middle.


SQL Injection.

Password Attacks.


17. What are the 3 elements of good cyber security?


The CIA triad refers to an information security model made up of the three main components: confidentiality, integrity and availability.


18. What are the 5 best methods used for cyber security?


Keep Your Software Up to Date. 

Use Anti-Virus Protection & Firewall.

Use Strong Passwords & Use a Password Management Tool.

Use Two-Factor or Multi-Factor Authentication. 

Learn about Phishing Scams – be very suspicious of emails, phone calls, and flyers.
