This is a guest post co-written by Sergio Delgado from YoucanBook.me. In their own words, “YouCanBook.me is a small, independent and fully remote team, who love solving scheduling problems all over the world.”

At YoucanBook.me, we like to say that we’re “a small company that does great things.” Many aspects of our day-to-day culture are derived from such a simple motto, but especially a great emphasis on the efficiency of our operations.

Although we’re far from the first years in which our CTO programmed the entire first version of our SaaS tool, when I joined the company, we were only five developers, of which only three were in charge of backend services, and none were dedicated to it 100%. The daily tasks of a programmer in a startup like ours are incredibly varied, from answering customer support requests to refining the backlog of tasks, defining infrastructure, or helping with requirements. The job is as demanding as it is rewarding, where the challenges never end, but that forces us to seek efficiency in everything we do. A project not very well defined, where we’re not very clear about the way forward and that can take months of research, is a challenge for a team like ours, and we’ll probably postpone it again and again to prioritize more urgent developments that bring value to our customers as soon as possible. For us, it’s very important to extract the maximum benefit from every development we make in the shortest possible time.

The result of this philosophy is our involvement with Amazon Web Services and its different platforms and tools. Although the early versions of our backend services didn’t run on AWS, the migration to the cloud allowed us to stop worrying about managing physical servers in a hosting company and focus our efforts on our business logic and code.

Currently, our backend servers are based on Java technology and run on AWS Elastic Beanstalk, while for the frontend we have a mix of JSP pages and React client applications. In JVMs, we deploy WAR files, which we compile from the source code that we store in AWS CodeCommit repositories using AWS CodeBuild scripts. In addition, all our monitoring is based on Amazon CloudWatch logs and metrics.

An interesting feature is that the different environments (such as development, pre-production, production, and analytics) are completely separate, but we manage them through AWS Organizations. AWS Identity and Access Management (IAM) users are created in a root account, and then assume roles to operate on the rest of them.

With all this, three people manage half-a-dozen services, across four different environments, running in dozens of instances and, quite simply, everything works.

Our problem

Although our services are all developed with Java technology, the truth is that not all of them share the same technology stack. Over the years, they have been migrating to more modern frameworks and standardizing their design, but not all of them have been able to update yet. We were aware that some services had clear performance issues and caused bottlenecks when there were high load spikes, especially the older code based on legacy technologies.

Our short-term solution was to oversize those specific services, with the consequent extra cost, and redeploy them in the long term following the architecture of our most modern applications. But we were sure that we could achieve very fast improvements if we invested in some performance analysis tool, or APM (Application Performance Monitoring). We knew there were many in the market and some of us had experience working with some of them, and good references from others. So we created a performance improvement project on our roadmap, researched a little of which products looked better and … not much more. We never found the time to spend weeks contacting suppliers, installing the tools, analyzing our services during the trial period, and comparing the results. That’s why performance tasks were constantly being postponed, always waiting for some time of the year where we didn’t have much else to do. Which was never going to happen.

Amazon CodeGuru Profiler arrives

One of the good habits we have is being very attentive to all the news of AWS, and we’re usually very quick to test them, especially when they don’t involve changes in our applications’ code.

In addition, relying on AWS products gives us an extra advantage. As a company policy, we love being able to define our security model about IAM users, roles, and permissions, rather than having to create separate accounts and users on other platforms. This rigorous approach to managing access and permissions for users of our infrastructure allows us to regularly undergo security audits and successfully overcome them without investing too much effort for a company of our size. In fact, our safety certifications are one of our differentials from our competitors.

That’s why we immediately recognized the opportunity Amazon CodeGuru Profiler offered us when it was announced at the re:Invent conference in late 2019. On paper, other APM tools we wanted to evaluate seemed to offer more information or a larger set of metrics, but the big question was whether they would be useful to us. What good were reporting screens if we weren’t sure what they meant or if they didn’t offer recommendations that we could implement immediately? Amazon CodeGuru seemed simple, but instead of seeing it as a disadvantage, we had the intuition that it could be a big benefit to us. By testing it, we could analyze the results in hours, not weeks, and find out if it really gave us value when it came to discovering the parts of the code that we needed to optimize.

The best thing about CodeGuru Profiler is that it would take us longer to discuss whether or not to use it than just install it and try it out. A single developer, the infrastructure manager, was able to install the CodeGuru agent on all our JVMs in one afternoon. We ran CodeGuru Profiler directly in the production environment, allowing us to analyze latencies and identify bottlenecks using actual production data, especially after a load peak. We realized that it’s much easier and more realistic for us than simulating a synthetic workload, and there’s no possibility of us defining it incorrectly or under untrue assumptions. All we find in CodeGuru is the authentic behavior of our systems

The following screenshot shows our systems pre-optimization.

The following screenshot shows our systems post-optimization.

Analysis

The flame graphs of CodeGuru Profiler were very easy for us to understand. We simply select the time interval in which we detected a scaling problem or peak workload and, for each server application, we see the Java classes and methods that contributed most to the latencies of our users’ requests. Because our business is based on integrating with different external calendar systems (such as Google, Outlook, or CalDAV) much of that latency is inevitable, but we quickly found two clear strategies for optimizing our code:

  • Identify methods that don’t make requests to third-party systems but nevertheless add significant time to latencies. In these cases, CodeGuru Profiler also offered recommendations to optimize the code and improve its performance.
  • See exactly what percentage of response times were due to which type of requests to the underlying calendars. Some requests (such as creating an event) don’t have much room for improvement, but we did find queries that were done much more frequently than we had estimated, and that could be largely avoided by a more appropriate search policy.

We got down to work and in a couple of weeks, we generated about 15 tickets in our backlog, most of which were deployed in production during the first month. Typically, each ticket requires hours of development, rather than days, and we haven’t undone any of them or identified any false positives in CodeGuru’s recommendations.

Aftermath

We optimized our oldest and worst-performing service to reduce its latency by 15% by the 95th percentile on a typical working day. In addition, our response time graphs are much flatter than before, because we eliminated latency spikes that occurred semi-regularly (see the following screenshot).

The improvement is such that, in one of the last peak loads we had on the platform, this service was no longer the bottleneck of the system. It supported all requests without problem or blocking the rest of our APIs.

This has saved us not only the cost of extra instances we no longer need (which we had running just to service in these scenarios), but dozens of work-hours in deeper refactoring over legacy code, which was just what we were trying to avoid.

Another of our backend services, which typically holds a very high workload during business hours, has improved further, reducing latency by up to 40%. In fact, on one occasion, we introduced an error in the configuration of our autoscaling and reduced the number of execution instances to only one machine. It took us a couple of hours to realize our failure because that single instance could handle all our users’ requests without any problem!

The future

Our use of CodeGuru Profiler is very simple, but it has been tremendously valuable to us. In the medium term, we’re thinking of sampling part of our servers or user requests instead of analyzing all production traffic, for efficiency. However, it’s not too urgent for us because our services are working perfectly well with performance analytics enabled, and the impact on response times for our users is imperceptible.

How long do we plan to have CodeGuru Profiler activated? The answer is clear: indefinitely. Improving problematic parts of our services that we more or less already knew is a very good result, but the visibility that it can offer us in future peak loads is extraordinarily valuable. Because, let’s not fool ourselves, we removed several bottlenecks but will have hidden ones, or introduce them with new developments. With CloudWatch metrics and alarms, we can detect when this happens and know what happened, but CodeGuru helps us know why.

If you have a problem similar to ours, or want to prevent it, we invite you to become more familiar with CodeGuru.

A single file that includes numerous supporting files is commonly known as a form template. Some files will define or show the controls to appear on the free form templates or design. The collections of these supporting files or templates are also called form files. While designing free form templates, users should be able to view and also work with the form files. 

It will create a new free form template by copying and storing those files within a folder. A form template (.XSN) file designing or creation of a single file will include various supporting files. Users may fill out the online form by accessing the .XML form file, which is a form template.

Designing Free Form Templates

There are numerous processes that define free form template design, and are as follows:

  • Designing the form’s appearance – the instructional text, labels, and controls
  • Controls will assist with user interaction behavior on the form template. You can design a specific section to appear or disappear when the user chooses a particular option
  • Whether the form template may include some additional views. For a permit application form design, for example, you have to provide different views for each person. One view especially for the electrical contractor, next for the receiving agent, and finally, the investigator. He or she will deny or approve the permit application
  • Next, you need to know how & where to store the form data. Designing free from templates will allow users to submit their data within the database either online or direct access. If not, they can also store the same in any specific shared folder
  • It is essential to design the other elements, colors, and fonts within the form template
  • Users must be able to personalize the form. Allowing users to include various rows within the optional section, repeating section, or a repeating table
  • Users should receive a notification when they forget to input a mandatory field or make mistakes within the form
  • After completing the free form templates design, you can publish the same online using a .XSN file format

Club Signup Form

A simple registration form can help your Club Signup Form creation process go smoother. This signup form could be an ideal solution for a new club membership registration for any organization or club.

Application Form

Application form templates are much easier to use & set-up to streamline your application process. You can customize this online form and utilize the same for numerous applications. Make use of this application form as a job application form, volunteer applications, contest entries, or high school scholarship applications. It is an ideal solution for scholarship programs, nonprofit organizations, business owners, and many such users and use cases.

Scheduling Form

Scheduling form templates are handy and can be used for numerous appointment booking requirements. A scheduling form is also utilized for various appointment scheduling or online reservations and booking purposes. Regardless of your business requirement, it is easy to customize the form template.

Concept Testing Survey

While testing a new design or concept, it is essential to gather the responses quickly. Freeform templates for a concept testing survey make it much easier to gather product feedback and reach the target audience. It is essential to conduct market research while planning to release a new product.

Are Chatbots Vulnerable? Best Practices to Ensure Chatbots Security

Published

on

Rebecca James

A simple answer is a Yes! Chatbots are vulnerable. Some specific threats and vulnerabilities risk chatbots security and prove them a wrong choice for usage. With the advancement in technology, hackers can now easily target the hidden infrastructure of a chatbot.

The chatbot’s framework has an opportunity for the attackers ready to inject the malicious codes or commands that might unlock the secured data of the customers and your business. However, the extent of the attack’s complexity and success might depend on the messaging platform’s security.

Are you thinking about how chatbots are being exposed to attacks? Well! Hackers are now highly advanced. They attack the chatbots in two ways, i.e., either by social engineering attack or by technical attacks.

  • An evil bot can impersonate a legal user by using backup data of the possibly targeted victims by social engineering attack. All such data is collected from various sources like the dark web and social media platforms. Sometimes they use both sources to gain access to some other user’s data by a bot providing such services.
  • The second attack is technical. Here also attackers can turn themself into evil bots who exchange messages with the other bots. The purpose is to look for some vulnerabilities in the target’s profile that can be later exploited. It can eventually lead to the compromise of the entire framework that protects the data and can ultimately lead to data theft.

To ensure chatbots security, the bot creators must ensure that all the security processes are in place and are responsible for restoring the architecture. The data flow via the chatbot system should also be encrypted both in transit and rest.

To further aid you in chatbot security, this article discusses five best practices to ensure chatbots security. So, let’s read on.

The following mentioned below are some of the best practices to ensure the security of chatbots.

It’s always feared that data in transit can be spoofed or tampered with the sophistication of cybercriminals’ technology and smartness. It’s essential to implement end-to-end encryption to ensure that your entire conversation remains secured. It means that by encryption, you can prevent any third person other than the sender and the receiver from peeping into your messages.

Encryption importance can’t be neglected in the cyber world, and undoubtedly the chatbot designers are adapting this method to make sure that their chatbot security is right on the point. For more robust encryption, consider using business VPNs that encrypt your internet traffic and messages. With a VPN, you can also prevent the threats and vulnerabilities associated with chatbots.

Moreover, it’s a crucial feature of other chat services like WhatsApp and other giant tech developers. They are anxious to guarantee security via encryption even when there’s strict surveillance by the government. Such encryption is to fulfill the legal principles of the GDPR that says that companies should adopt measures to encrypt the users’ data.

User identity authentication is a process that verifies if the user is having secure and valid credentials like the username and password. The login credentials are exchanged for having a secure authentication token used during the complete user session. If you haven’t, then you should try out this method for boosting user security.

Authentication timeouts are another way to ensure your chatbots security. This method is more common in banks as the token can be used for the predetermined time.

Moreover, two-factor authentication is yet another method to prove user identity. Users are asked to verify identity either by a text message or email, depending on the way they’ve chosen. It also helps in the authorization process as it permits access to the right person and ensures that information isn’t mishandled or breached.

The self-destructive message features open another way for enhancing chatbot security. This option comes in handy when the user provides their personally identifiable information. Such information can pose a serious threat to user privacy and should be destroyed or deleted within a set period. This method is handier when you’re associated with backing or any other financial chatbots.

By using secure protocols, you can also ensure chatbots security. Every security system, by default, has the HTTPS protocol installed in it. If you aren’t an IT specialist, you can also identify it when you view the search bar’s URL. As long as your data is being transferred via HTTPS protocol and encrypted connections, TLS and SSL, your data is secured from vulnerabilities and different types of cyber-attacks.

Thus, make sure to use secure protocols for enhanced security. Remember that when Chatbots are new, the coding and system used to protect it is the same as the existing HIMs. They interconnect with their security systems and have more than one encryption layer to protect their users’ security.

Do you know what the most significant security vulnerability that’s challenging to combat is? Wondering? Well! It’s none other than human error. User behavior must be resolved using commercial applications because they might continue to believe that the systems are flawed.

No doubt that an unprecedented number of users label the significance of digital security, but still, humans are the most vulnerable in the system. Chatbot security continues to be a real big problem until the problem of user errors comes to an end. And this needs education on various forms of digital technology, including chatbots.

Here the customers aren’t the ones who are to be blamed. Like customers, employees can make a mistake, and they do make most of the time. To prevent this, the chatbot developers should form a defined strategy, including the IT experts, and train them on the system’s safe use. Doing so enhances the team’s skillset and allows them to engage with the chatbot system confidently.

However, clients can’t be educated like the employees. But at least you can provide them a detailed road map of securely interacting with the system. It might involve other professionals who can successfully engage customers and educate them on the right way to interact with the chatbots.

Several emerging technologies are keen to play a vital role in protecting the chatbots against threats and vulnerabilities in the upcoming time, among all the most potent method behavior analytics and Artificial Intelligence developments.

  • User Behavioral Analytics: It’s a process that uses applications to study the patterns of user behavior. It enables them to implement complex algorithms and statistical analysis to detect any abnormal behavior that possibly represents a security threat. Analytical tools are quite common and powerful; thus, this methodology can become a fundamental component of the chatbot system.
  • Developments in AI: Artificial technology is a two-end sword that offers benefits and threats simultaneously. But, as AI is predicted to fulfill its potential, it will provide an extra security level to the systems. It is mainly because of its ability to wipe a large amount of data for abnormalities that recognizes security breaches and threats.

The Bottom Line

Security concerns have always been there with new technologies and bring new threats and vulnerabilities with them. Although chatbots are an emerging technology, the security practices that stand behind them are present for a long time and are effective. Chatbots are the innovative development of the current era, and emerging technologies like AI will transform the way businesses might interact with the customers and ensure their security.

What’s the Best Tech Stack for Mobile App Development? Read To Know

Which is the Best Tech Stack for Mobile Application Development? Kotlin, React Native, Ionic, Xamarin, Objective-C, Swift, JAVA… Which One?

Image Source: Google

Technology Stack for smartphones is like what blood is for the human body. Without a technology stack, it is hard even to imagine smartphones. Having a smartphone in uncountable hands is rising exponentially. For tech pundits, this is one unmissable aspect of our digital experience wherein tech stack is as critical as ROI.

The riveting experience for a successful mobile app predominantly depends on technology stacks.

The unbiased selection of mobile apps development language facilitates developers to build smooth, functional, efficient apps. They help businesses tone down the costs, focus on revenue-generation opportunities. Most importantly, it provides customers with jaw-dropping amazement, giving a reason to have it installed on the indispensable gadget in present times.

In today’s time, when there are over 5 million apps globally, and by all conscience, these are whopping no.s and going to push the smartphone industry further. But now you could see mobile app development every ‘nook and corner.’ But the fact is not who provides what but understanding the behavioural pattern of users.

So the pertinent question is, which is the ideal tech stack to use for mobile app development?

In native mobile app development, all toolkits, mobile apps development language, and the SDK are supported and provided by operating system vendors. Native app development thus allows developers to build apps compatible with specific OS environments; it is suitable for device-specific hardware and software. Hence it renders optimized performance using the latest technology. However, since Android & iOS imparts — — a unique platform for development, businesses have to develop multiple mobile apps for each platform.

1. Waz

2. Pokemon Go

3. Lyft

1.Java: The popularity of JAVA still makes it one of the official programming languages for android app development until the introduction of Kotlin. Java itself is at the core of the Android OS. Many of us even see the logo of Java when the device reboots. However, contradictions with Oracle (which owns the license to Java) made Google shift to open-source Java SDK for versions starting from Android 7.0 Nougat

2.Kotlin: According to Google I/O conference in 2019- Kotlin is the officially supported language for Android app development. It is entirely based on Java but has a few additions which make it simpler and easier to work.

It’s my gut feeling like other developers to say that Kotlin is simply better. It has a leaner, more straightforward and concise code than open-cell Java, and several other advantages about handling null-pointer exceptions and more productive coding.

HERE’S A Programming Illustration Defining the CONCISENESS OF KOTLIN CODE

public class Address {

private String street;

private int streetNumber;

private String postCode;

private String city;

private Country country;

public Address(String street, int streetNumber, String postCode, String city, Country country) {

this.street = street;

this.streetNumber = streetNumber;

this.postCode = postCode;

this.city = city;

this.country = country;

}

@Override

public boolean equals(Object o) {

if (this == o) return true;

if (o == null || getClass() != o.getClass()) return false;

Address address = (Address) o;

if (streetNumber != address.streetNumber) return false;

if (!street.equals(address.street)) return false;

if (!postCode.equals(address.postCode)) return false;

if (!city.equals(address.city)) return false;

return country == address.country;

}

@Override

public int hashCode() {

int result = street.hashCode();

result = 31 * result + streetNumber;

result = 31 * result + postCode.hashCode();

result = 31 * result + city.hashCode();

result = 31 * result + (country != null ? country.hashCode() : 0);

return result;

}

@Override

public String toString() {

return “Address{“ +

“street=’” + street + ‘\’’ +

“, streetNumber=” + streetNumber +

“, postCode=’” + postCode + ‘\’’ +

“, city=’” + city + ‘\’’ +

“, country=” + country +

‘}’;

}

public String getStreet() {

return street;

}

public void setStreet(String street) {

this.street = street;

}

public int getStreetNumber() {

return streetNumber;

}

public void setStreetNumber(int streetNumber) {

this.streetNumber = streetNumber;

}

public String getPostCode() {

return postCode;

}

public void setPostCode(String postCode) {

this.postCode = postCode;

}

public String getCity() {

return city;

}

public void setCity(String city) {

this.city = city;

}

public Country getCountry() {

return country;

}

public void setCountry(Country country) {

this.country = country;

}

}

class Address(street:String, streetNumber:Int, postCode:String, city:String, country:Country) {

var street: String

var streetNumber:Int = 0

var postCode:String

var city: String

var country:Country

init{

this.street = street

this.streetNumber = streetNumber

this.postCode = postCode

this.city = city

this.country = country

}

public override fun equals(o:Any):Boolean {

if (this === o) return true

if (o == null || javaClass != o.javaClass) return false

Val address = o as Address

if (streetNumber != address.streetNumber) return false

if (street != address.street) return false

if (postCode != address.postCode) return false

if (city != address.city) return false

return country === address.country

}

public override fun hashCode():Int {

val result = street.hashCode()

result = 31 * result + streetNumber

result = 31 * result + postCode.hashCode()

result = 31 * result + city.hashCode()

result = 31 * result + (if (country != null) country.hashCode() else 0)

return result

}

public override fun toString():String {

return (“Address{“ +

“street=’” + street + ‘\’’.toString() +

“, streetNumber=” + streetNumber +

“, postCode=’” + postCode + ‘\’’.toString() +

“, city=’” + city + ‘\’’.toString() +

“, country=” + country +

‘}’.toString())

}

}

I’d say KOTLIN IS THE BEST FIND FOR ANDROID APP DEVELOPMENT.Google has dug deeper with some plans ahead since announcing it as an official language. Moreover, it signals Google’s first steps in moving away from the Java ecosystem, which is imminent, considering its recent adventures with Flutter and the upcoming Fuchsia OS.

Objective C is the same for iOS what Java is for Android. Objective-C, a superset of the C programming language( with objective -oriented capabilities and dynamic run time) initially used to build the core of iOS operating system across the Apple devices. However, Apple soon started using swift, which diminishes the importance of Objective -C in comparison to previous compilations.

Apple introduced Swift as an alternative to Objective-C in late 2015, and it has since been continued to be the primary language for iOS app development.Swift is more functional than Objective-C, less prone to errors, dynamic libraries help reduce the size and app without ever compromising performance.

Now, you would remember the comparison we’ve done with Java and kotlin. In iOS, objective-C is much older than swift with much more complicated syntax. Giving cringeworthy feel to beginners to get started with Objective-C.

THIS IS WHAT YOU DO WHEN INITIALIZING AN ARRAY IN OBJECTIVE-C:

NSMutableArray * array =[[NSMutableArray alloc] init];

NOW LOOK AT HOW THE SAME THING IS DONE IN SWIFT:

var array =[Int]()

SWIFT IS MUCH MORE ` WHAT WE’VE COVERED HERE.

In cross-platform app development, developers build a single mobile app that can be used on multiple OS platforms. It is made possible by creating an app with a shared common codebase, adapted to various platforms.

Popular Cross-platform apps:

  1. Instagram
  2. Skype
  3. LinkedIN

React Native is a mobile app development framework based on JavaScript. It is used and supported by one of the biggest social media platforms- Facebook. In cross-platform apps built using React Native, the application logic is coded in JavaScript, whereas its UI is entirely native. This blog about building a React Native app is worth reading if you want to know why its stakes are higher.

Xamarin is a Microsoft-supported cross-platform mobile app development tool that uses the C# programming language. Using Xamarin, developers can build mobile apps for multiple platforms, sharing over 90% of the same code.

TypeScript is a superset of JavaScript, and is a statically-typed programming language supported by Microsoft. TypeScript can be used along with the React Native framework to make full use of its error detection features when writing code for react components.

In Hybrid mobile app development, developers build web apps using HTML, CSS & JavaScript and then wrap the code in a native shell. It allows the app to be deployed as a regular app, with functionality at a level between a fully native app and a website rendered(web browser).

Apache Cordova is an open-source hybrid mobile app development framework that uses JavaScript for logic operations and while HTML5 & CSS3 for rendering. PhoneGap is a commercialized, free, and open-source distribution of Apache Cordova owned by Adobe. The PhoneGap platform was developed to deliver non-proprietary, free, and open-source app development solutions powered by the web.

Ionic is a hybrid app development framework based on AngularJS. Similar to other hybrid platforms, it uses HTML, CSS & JavaScript to build mobile apps. Ionic is primarily focused on the front-end UI experience and integrates well with frameworks such as Angular, Vue, and ReactJS.

To summarize, there are 3 types of mobile apps- Native mobile apps, Cross-platform mobile apps, and Hybrid mobile apps; each offers unique technologies, frameworks, and tools of their own. I have enlisted here the best mobile app technology stacks you could use for mobile app development.

The technologies, tools, and frameworks mentioned here are used in some of the most successful apps. With support from an expert, a well-established mobile app development company, that may give much-needed impetus in the dynamic mobile app development world.
