If you want to transfer or share files with someone else, it’s important that they are also connected via a local area network (LAN). 

This way, each person can access their own files through a single connection point at any time without going through another machine before accessing them again later on their own device.

Network protocols include:

  • Internet Protocol Suite (IP) defines how packets move across the internetwork. It includes routing table entries used by routers so they know where certain messages should go next based on destination addresses contained within those packets themselves;

11. Ethical Hacking For Beginners

Ethical hacking is a way of hacking used to improve a system’s security. It’s not illegal, but it can be seen as unethical if you do it for personal gain. 

Most people will hire an ethical hacker to test their systems and find vulnerabilities in them so that they can fix them before anyone else finds out about them.

14. Enabling End-To-End Security For Data In Transit

End-to-end security protects data in transit. With end-to-end, each step of the data’s journey from sender to receiver is encrypted and authenticated by both parties. 

This prevents hackers from intercepting or altering information at any point along its route and ensures that only authorized users can view or manipulate it.

While this approach has been used for years by companies like Gmail, Yahoo!, and Facebook (among others), it’s only recently become more popular among online security practitioners due to its ability to prevent attackers from accessing sensitive information. 

It also protects users’ privacy concerns regarding personalized ads or targeted advertisements based on their browsing history or location data collected through cookies. 

This is collected when surfing websites within local networks owned by companies affiliated with Google Inc., Apple Inc., Microsoft Corp., Mozilla Foundation Ltd., etcetera.

15. OSINT 101

OSINT is a subset of intelligence gathering, discovering information about people, organizations, and other entities from publicly available sources.

What is .NET?

.NET is a general-purpose programming language that Microsoft designed and implemented to support the development of software applications for Windows, Linux, and mobile devices. 

It’s also known as Common Language Runtime (CLR) or Common Language Infrastructure (CLI). How do you build secure .NET applications?

You must ensure that your application uses algorithms resistant to side-channel attacks like timing and memory leaks.

You can do this by using object-oriented programming techniques such as encapsulation, information hiding, and polymorphism, where each class has its own functionality.

It also shares common traits with other classes in order not only to reduce code duplication but also to prevent data leaks through public/private access control rules.

17. Basics Of Online Safety

Online safety is a term that refers to the practice of avoiding risks associated with online activities.

  •  Spamming/phishing/vishing/smishing etc.

19. Introduction To Cryptocurrency Treasury Management Essentials

Cryptocurrency is a digital currency. A central bank or government does not back it, and any authority does not regulate it.

Cryptocurrency is used in transactions between two parties who agree on the price of their respective cryptocurrencies before transacting.

21. Getting Started With Cybersecurity For Small Businesses

Cybersecurity is important for small businesses because it can help them avoid financial loss and protect their customers’ data.

Cybersecurity is not just about protecting your data but also protecting your customers’ data. Cybersecurity isn’t just a technical issue; it’s a people issue. 

You need to understand the needs of your employees and the public they serve to keep them safe online while keeping costs down through automation and less reliance on manual processes.

22. The Art And Science Of Cyber-Security Risk Assessment

Risk assessment is the process of analyzing and evaluating the risk associated with a particular course of action. 

It involves determining whether or not an action’s consequences are likely to be positive or negative and then making adjustments if necessary. 

For example, if you’re considering buying a new house in your neighborhood but don’t know much about it yet, how can you tell if it’s safe? 

In order to answer this question properly, you will need to research crime rates in the area where your home will be located before deciding whether or not buying there makes sense for your family.

There are two categories of risk assessment: qualitative and quantitative. Qualitative assessments look at things like demographics and past crimes.

However, quantitative assessments look at statistics instead because they provide more accurate data points for comparison purposes later down the road when comparing different locations across town/state/country, etcetera.

23. The Changing World Of International Privacy And Data Protection Law

The GDPR is a new European Data Protection Directive that went into effect on May 25, 2018. 

It requires companies to have robust privacy and data protection policies, including the right to be forgotten, effective consent for personal processing data, etc. What does this mean for companies that handle personal data?

It’s complicated. You need to understand how your business works with people who have their own individual rights under the GDPR. 

In addition, there are also international standards such as the Swiss Federal Data Protection Act (the “Swiss Act”), which has some of its own requirements as well as overlapping provisions from other jurisdictions like Canada’s Personal Information Protection and Electronic Documents Act (“PIPEDA”).

24. Managing Cybersecurity Risk And Compliance In The Cloud Era

The Cloud computing era is used for enabling sufficient, on-demand access to a shared pool of computing resources. 

There are servers, networks, storage, services, and application that can be provisioned and released with little management effort or service provider interaction. 

Cloud providers typically use cloud platforms such as Amazon Web Services (AWS) or Microsoft Azure to provide services like computing power, database storage, and communication links between computers over the Internet. 

The best way to think about cloud computing is that it’s just another way of delivering infrastructure technology rather than replacing it with something else entirely.

25. Modernizing Your Applications Via Windows 10 Enterprise Security Features​

Windows 10 Enterprise Security Features

  • Windows 10 has many security features that make it more secure than previous versions of Windows.
