\nHow to Implement Phone Login
\nNow that you have read all the advantages of using a phone login and you are planning to implement it for your business, too, your first question will be, \"How can I implement this thing on my website.\" Right ??
\nDon't worry, we've got you covered.
\nLet's start with the first scenario where the user submits the phone number to the App backend through GUI. After submitting the number, they land on a new page which asks for a token. The application backend verifies the input number and combines it with extra information such as IP address, geographical location, and device information. This wholesome mixture of information is now submitted to the User service, which generates a token, and then they associate it with these requests. Here is an important aspect that you need to keep in mind: The generation of a token. See, this generated token will help us in many ways, and they are essential as well. These tokens can be used to expire the ongoing sessions or logging out of an idle account. And many more things like this, which increases the security of your user's account. Now our next challenge is how do we send OTP to the consumers. This will be done by your User Service, which will call a telephony API and will send the OTP to the consumers' phone number as an SMS. Many companies provide this functionality, and LoginRadius is one of them. On receiving the One-time password in SMS, the user will now enter the OTP in the form. Once again, the application backend comes into action and verifies the token which was sent by User Service. If the token is exactly the same as what was sent, the user is logged into the account. Simple! Now that you know how to implement phone login, you must be excited to implement it for your website too. But there are a few things we need to keep in mind while implementing this feature. In this article, we talked about applying a simple approach of using Phone Login on the websites and how it will enhance the businesses. This feature removes the consumer's mental load to remember each password created on different websites. Finally, before implementing any functionality on your website, analyze and consider the pros and cons from every possible angle. Cheers! A list is a set of index-accessible objects that provides functionality for searching, sorting, and manipulating list items. C# List class represents a collection of strongly typed objects that can be accessed by using the index. In this article, we learn how to work with lists in C# using the C# List class to add, remove, and search items in a collection of objects using List class methods and properties. We can create a list by calling the As we have discussed above, Here T is the type of object for which we have to create the list. The type is Note: If we have created the list using the capacity value and when more than the defined capacity elements are added, the list size will automatically increase. We can add elements directly into when we have created a list or add elements after creating a list. I will discuss both methods here. The list has mainly two properties. To get all the elements of a list, we have to loop through the list. We can use for or foreach loop to get the elements. Below is the code to get all the elements using both the loops and print the element's values. In this method, we have to run the loop till the last element of the list. For that, I have used the Count property of the list Both the methods will give the same output. I am taking the above list example so the result will be Output: To remove items from a list, we can use various list methods. In this article, we have discussed the basics of Did you know that in only a few minutes, a DDoS attack can bring your website down? Hackers are targeting your site and overloading your network and your server. Your website becomes unresponsive, unavailable and can even go entirely offline. We'll show you how DDoS attacks can be avoided. A Distributed Denial of Service (DDoS) is a targeted cyber attack on a website or device where a malicious attacker's flood of traffic is sent from single or multiple sources. The primary purpose of DDoS is to make a machine or network resource unavailable to its genuine users by temporarily or disrupting the services of a host connected to the Internet. If we do not use appropriate security practices or tools, it makes your application into a non-functional situation. The malicious attacker uses multiple compromised computer systems or devices or IoT devices for the attack. These all compromised devices make the DDoS attacks more effective. DDoS mitigation is a process in which we have used a set of techniques or tools for minimizing or mitigating the impact of distributed denial-of-service (DDoS) attacks on the targeted servers or networks. The Volume Based Attack DDoS attack is the most common DDoS attack. An attacker uses multiple methods to generate massive traffic volumes to overwhelms a machine's network bandwidth because of creating massive volume traffic that makes it impossible for legitimate traffic to flow into or out of the targeted site. The machine continually has to check the malicious data requests and has no room to accept legitimate traffic. We can detect this type of attack easily. The Protocol attacks target Layer 3 and Layer 4. Attackers use malicious connection requests for consuming the processing capacity of network infrastructure resources like servers, firewalls, and load balancers. An SYN flood (half-open attack) is the most common way; in this attack, the attacker sends repeated initial connection requests and overwhelms all available ports on a targeted server machine or device. The Application attacks target Layer 7, which is the topmost layer in the OSI network model. This layer is closest to the end-user, which means both the OSI application layer and the user interact directly with the software application. These attacks are typically small in volume compared to the other layers attacks, so these attacks are not easy to catch, i.e., a small number of HTTP requests on a login page. A Web Application Firewall (WAF) is a set of rules or policies that helps protect web applications or APIs from malicious traffic. WAF sits between an application and the HTTP traffic and filters the common web exploits that can affect availability. There are various WAF solutions available, but you need to analyze which WAF solution is suitable for your application. Attackers can make so many repeated calls on the APIs. It can make resources unavailable to its genuine users. A rate limit is the number of API calls or requests that a user can make within a given time frame. When this limit is exceeded, block API access temporarily and return the 429 (too many requests) HTTP error code. I m adding node js examples to implement the rate limit. multiple npm packages are available for node js NodeJs Active cache means if the service first attempts to read from the cache backend and falls back to reading from the actual source. The service is not dependent on requesting the data from the real upstream server. A cache backend is a key-value store (e.g., Redis) or In-Memory cache, and the actual source of data is SQL, MongoDB, etc. Passive cache architecture ensures high volume traffic never hits to actual server or service. I m adding node js examples to implement the passive cache. multiple npm packages are available for node js NodeJs Several vendors provide DDoS mitigation services as software as a service model. They have charged a license fee the first time then charge according to service usages. The Cloud-based DDoS mitigation solution has a lot of advantages. They have dedicated staff, better reaction time, High network bandwidth than private networks to perform better in case of volume-based DDoS attack. Multi cross-region availability with auto replica or backup so you can switch to your application load next available region without impacting your actual users, updated policies or rule set, a better experience for handling DDoS attacks. The DDoS attacks are increasing day by day. Organizations need to prepare for any attack. If the organization does not prepare in advance and any attack happens, that case damage control can take months and impact the organization's reputation.

\nWhat is List in C#?
\nList<T> class in C# cotains a strongly typed list of objects. It provides functionality to create a list of objects, add list items, search, sort and manipulate list items. In List<T>, T is the type of objects like int, string, or any user-defined object.List<T> is required when we have multiple items with the same object, like data of student's marks or data of various subject's names (string). In that case, we can use List<T> to maintain that data into a list.List<T> comes under the System.Collection.Generic namespace and the index start from 0.How to Create a List?
\nList<T> constructor; It takes an argument of int type that is the list's capacity. If we do not define the capacity, then the list size will be dynamic and every time an element is added, the list size is increased. The list can be created using the below syntax.
\nList<int> lst=new List<int>(); // list with dynamic capacity\nList<int> lstCapacity=new List<int>(10); // list with capacity of 10 elementsint in the above code, which means we can store the int type of variable's value.Add elements into a list
\n\n
\n
\nList<int> lst = new List<int>\n{\n 1,2,3,4,5,6\n};\n
\n
\nList<int> lst = new List<int>();\nlst.Add(1);\nlst.Add(2);\nlst.Add(3);\nlst.Add(4);\nlst.Add(5);\nlst.Add(3);Properties of a list
\n\n
\n
\nList<int> lst = new List<int>();\nConsole.WriteLine(lst.Capacity); //Prints 0-- Default\nList<int> lst1 = new List<int>(5);\nConsole.WriteLine(lst1.Capacity); // Prints 5\n
\n
\nList<int> lst = new List<int>(5);\nConsole.WriteLine(lst.Count); // Prints 0\nlst.Add(1);\nlst.Add(2);\nConsole.WriteLine(lst.Count); //Prints 2Read all elements of a list
\n
\n\nforeach (var item in lst)\n{\n Console.WriteLine(item);\n}
\nfor (int i = 0; i < lst.Count; i++)\n{\n Console.WriteLine(lst[i]);\n}
\n1\n2\n3\n4\n5\n3Remove element from a list
\n\n
\n
\nlst.Remove(3); // Removes the fist occurance of element 3\n
\nPredicate<T> match)- This method removes all elements from a list that matches the condition defined by the specified predicate. We have to pass the predicate as a parameter.
\nlst.RemoveAll(x=>x==3); // Removes all the elements 3\n
\n
\nlst.RemoveAt(0); // Removes 0th index element from a list\n
\n
\nlst.RemoveRange(0,2); // Removes element 1,2 because the starting index is 0 and count is 2\n
\n
\nlst.Clear(); // Removes all elements from a listConclusion
\nList<T>, properties, and some methods. The main advantage of using the list is that it is faster and it is more friendly because it gives us many inbuilt methods to use and do the manipulation according to ourselves.
