Some video issues (audio problems, spelling issues, editing), the background web app is not particularly good at "handing off" lessons and you will repeat MANY videos, most weblinks are 404 errors.

Best tip for these courses get a notebook and write down the question thats put at the beginning of each video then answer it by the end if you do this you will have no problem completing any course!

Title: Safeguarding Digital Frontiers: A Review of Cybersecurity Tools and Attacks
Introduction: In the age of pervasive technology and interconnected systems, the importance of cybersecurity cannot be overstated. As the digital landscape continues to evolve, both organizations and individuals face an escalating threat from cyber attacks. To combat these dangers, a multitude of cybersecurity tools have emerged, designed to fortify our digital frontiers and protect against various forms of attacks. This review aims to shed light on the diverse array of cybersecurity tools available and delve into the intricate world of cyber attacks, highlighting their evolving nature and the measures required to mitigate them.
a) Firewall Solutions: Firewalls act as a first line of defense by monitoring and filtering incoming and outgoing network traffic. They provide granular control over network traffic and help prevent unauthorized access to systems.
b) Antivirus and Anti-Malware Software: These tools detect, quarantine, and eliminate malicious software such as viruses, worms, Trojans, and spyware. They employ heuristic analysis and real-time scanning to identify and neutralize threats.
c) Intrusion Detection and Prevention Systems (IDPS): IDPS tools monitor network traffic for suspicious activities and provide alerts or take action to prevent potential intrusions. They offer an additional layer of security by detecting and mitigating attacks in real-time.
d) Vulnerability Assessment Tools: These tools scan networks, systems, and applications to identify vulnerabilities that can be exploited by attackers. They help organizations prioritize and remediate security flaws before they are exploited.
e) Data Encryption Tools: Encryption tools protect sensitive data by converting it into an unreadable format, which can only be decrypted with a specific key. They play a vital role in safeguarding data during transmission and storage.
a) Phishing Attacks: Phishing involves the use of deceptive emails or websites to trick users into revealing sensitive information such as passwords or credit card details. Attackers often masquerade as trustworthy entities to lure victims into their traps.
b) Ransomware Attacks: Ransomware is a malicious software that encrypts a victim's data and demands a ransom in exchange for decryption. It has gained prominence due to its disruptive nature, targeting both individuals and organizations.
c) Distributed Denial of Service (DDoS) Attacks: DDoS attacks flood a target system or network with an overwhelming volume of traffic, rendering it inaccessible to legitimate users. Attackers often use botnets to orchestrate these attacks.

Informative, well structured course. The main issue I have with it is the quality of audio. In many videos microphone quality, used for recording, was absolutely abysmal. The only saving grace in those videos were captions below the video. Although, in some rare cases the captions were in fact, completely incorrect or simply state, that the audio is INAUDIBLE. Moreover, some instructors speak too slow, but I don't consider it particularly a bad thing, because coursera provides the ability of speeding up the videos, which allows you to adjust the tempo to your preference. Finally, there were some minor errors on this course, speficailly with some quizes, for example week 1 quiz has a question of the topic that will only be discussed in week 4, this may demotivate some learners, who carefuly took-in all the information taught in the course throughout the week, only to find a question which was not discussed. Overal: To me personaliy, the drawbacks were not significant, I still enjoyed the course and the information provided. I love how each section and topic is structured. Moreover, I am glad, that many of the topics inter-connect with one another and you get to learn things gradually getting deeper and deeper into subject matter, while reinforcing your already acquired knowledge.
