Introduction

The increased availability of technology and subsequent use of it have had a significant impact on how people communicate and conduct their daily lives. The internet, for example, connects people and businesses worldwide swiftly, simply, and affordably.

However, the internet and computers can be misused in harmful ways, wreaking havoc on societies. Cybercrime is a hazard to businesses and individuals who use computers that are connected to the internet, particularly mobile technology.

Cybercrime can be defined as a type of criminal conduct that primarily targets or includes the use of a computer, a computer network, or a connected device. Cybercrime is not only carried out by individuals or hackers; businesses can also carry it out. The basic goal of cybercrime is to cause personal or political harm to computers for monetary gain. Cybercrime is a broad phrase that refers to a variety of unlawful behaviors that are carried out using a computer or the Internet.

Common ways in which cybercrime occurs

Malware

A computer virus infects computers, corrupts files, and disrupts the machine’s overall operation. It also copies itself, causing damage to other devices and systems. A virus is a type of malware that includes harmful software, programs, or instructions that are designed to harm or corrupt data, steal it, and profit from it. This includes ransomware, which requires you to pay a ransom in order to access data that has been locked, as well as adware, which will bombard you with unwanted advertisements.

• Cyber Bullying

It includes all forms of online harassment, such as sexual harassment, stalking, and doxing, which refers to the release of personal information without the consent of the individual, as well as framing.

• Phishing

Phishing campaigns are when spam emails or other kinds of communication flood recipients’ inboxes, tricking them into performing activities that put their security at risk. Infected attachments or links to sites or viruses are included in these emails or contacts. They may also request personal details. Spear-phishing attacks deceive particular targets into jeopardizing their personal or corporate security. Spear-phishing efforts are designed to appear very trustworthy, with no obvious signs that they are fake.

• Cyber Extortion

It’s a computerized version of money extortion, exactly as it sounds. Ransomware is one of the most frequent ways to encrypt files and then demand money in exchange for their decryption. Other forms of cyber extortion include blackmailing victims by releasing personal information, images, and videos, as well as threatening businesses with DDoS assaults (which shut down a system or network).

• Cyber Espionage

Cybercriminals can also be state-sponsored organizations that infiltrate the complex web of international networks of countries and prominent organizations in order to foment war, strife, division, and other catastrophic events around the world.

The roots of cybercrime

There can be a myriad of ways in which computers find themselves vulnerable to cyber-attacks, which has brought forward an urgent call to action for lawmakers over to world to come up with solutions to protect individuals and organizations alike. Some of the reasons for the vulnerability of computers may be said to be:

1. Accessibility

The difficulties in preventing unauthorized access to a computer system originate from the fact that there is always the chance of unauthorized entry, not because of human error, but because of the complicated technology. Many security systems can be bypassed by discreetly implanting a logic bomb, key loggers that can steal access codes, advanced voice recorders, retina imagers, and other devices that can trick biometric systems and penetrate firewalls.

2. Complexity

Operating systems are used by computers, and these operating systems are made up of millions of lines of code. The human brain is faulty, and it is impossible to rule out the possibility of a lapse at any point. Cybercriminals use these flaws to get access to the computer system, frequently utilizing more sophisticated methods than the systems engineers might’ve anticipated.

3. Negligence

Negligence is inextricably linked to human behavior. As a result, it’s extremely likely that neglect occurred while defending the computer system, allowing a cybercriminal to gain access and control of the computer system. The improvement of security barriers within software packages and network structures could lead to improved security. This negligence is usually a property of under-resourced IT security provisions, and the improvement of security barriers within software packages and network structures could lead to improved security.

Cybercrime against individuals

This category of cybercrime involves ordinary individuals who may not practice careful digital habits while surfing the internet. One of the more widely occurring instances of cybercrime against individuals is cybercrime against children and minors. Intellectuals have pointed out that the internet has allowed child pornography by providing offenders with a variety of unrestricted avenues to exchange information and an opportunity to acquire and improve abilities unlawfully. As a result of predators’ increased activity in establishing open relationships with young victims such as teens, the number of youngsters who use the internet and transmit child pornography has increased, posing a severe threat to children’s safety.

Solution

One of the frequently proposed solutions is for parents to be responsible for their children’s online behavior. However, parents are unable to shoulder this responsibility alone because it is difficult and challenging for them to always be present with their children while they are surfing the Internet. As a result, this problem can be solved by close collaboration between parents and governments.

Furthermore, parents can educate their children to avoid risks such as communicating with strangers on the internet, which can lead to harmful circumstances. Parents should not rely solely on software to keep track of the websites their children visit.

Outside the home, responsibility can be taken by states, which might prove to have a real effect on the safety of children. Operation Ore, a British Police operation in 2003, led to 1,600 arrests in the UK of individuals who had subscribed to a US-based child pornography website; the arrests were made possible by cooperation with US law enforcement authorities, who provided credit card details of UK residents who had subscribed to the service.

Cybercrime against organizations

The second type of cybercrime is one that poses a serious threat to businesses and political websites, to mention a few examples. It is fairly typical for hackers to concentrate their efforts on a single target, which is commercial websites such as shopping sites and banks. Cybercrime against commercial websites can take many forms, but one typical activity among hackers is piracy, which includes illegally downloading music, videos, and games, as well as stealing information or any substances that are private or not made readily accessible. The Record Industry Association of America (RIAA), for example, claims that illegally downloaded music costs the economy $12.5 billion per year.

Solution

In order to combat cyber-attacks, companies have been suggested to create and safeguard their websites by implementing anti-piracy softwares, which may help to lower the danger of cybercrime and its associated activities. Furthermore, organizations should acquire smart and experienced computer security experts to oversee their information and resources, ensuring a secure atmosphere in cyberspace.

Companies should be encouraged to join a variety of organizations and international cooperation groups in order to counter piracy and build an international law in cyberspace that punishes anyone who engages in cybercrime.

Other practices to prevent cybercrime

1. Become vigilant when browsing the internet.
2. Avoid opening suspicious emails with dodgy links or attachments.
3. Never click on unknown links or advertisements.
4. Make sure to update your computer with software updates.
5. Make sure you have strong, unique passwords that are a combination of letters, numerals, and symbols.
6. Always have an antivirus installed that will throw warnings and protect your systems from attacks.

Conclusion

Hackers seem to be taking over our systems in the present age of technology, and no one seems to be safe. The average dwell time, or the amount of time it takes for a corporation to identify a cyber breach, is over 200 days. Most internet users are unconcerned about the possibility of being hacked, and they rarely change or update their passwords. As a result, many people are vulnerable to cybercrime, thus, it’s critical to educate yourself. Educate yourself and others on the precautions you can take to protect yourself as an individual or as an organization.

What is edge?

The term “edge” describes computational infrastructure that is located close to data origin sources. In simple words Edge is the entry point to the network where devices themselves are communicating with the Internet. In a distributed IT architecture and infrastructure, data is processed as close to the original source as is feasible at the network’s edge.

What is Edge Computing?

“A component of a distributed computing topology in which information processing is positioned close to the edge — where things and people produce or consume that information,” is how edge computing is defined. Edge computing, to put it simply, is the practice of shifting fewer processes from the cloud to local locations, such as a user’s PC, an IoT device, or an edge server. The amount of long-distance communication between the client and server decreases if computation is moved to the network’s edge.

How Edge Computing Works?

Fig 2: Wikipedia

In traditional enterprise computing, generally data passed from client through WAN like the Internet. After enterprise applications process that data, send the results back to the client endpoint. But as the number of devices connected to the Internet increases, too much data will pass to the centralized data center resulting in server failure. That’s why now IT industries are moving towards infrastructures like Edge Computing. In edge computing we moved storage and computing resources to the point where data is generated. So, the access and processing time gets reduced. And that will result in an increase in efficiency of the system. Processing frequently includes normalizing and analyzing the data stream in search of business intelligence, with only the findings of the analysis sent back to the main data center. Basically, edge computing is not a new terminology. It has been used for decades like remote offices and Branch offices where it was more reliable and efficient to locate computing resources at the desired location rather than rely on a single central site.

Edge Vs Cloud Computing

While comparing Edge computing with Cloud, we will come to know that the main difference is the place where the data is processed. In Edge Computing, data processes at information sources like IOT devices, while in Cloud Computing data processing happens at the centralized cloud server which is very far away from the information source.

Edge Computing and 5G

Fig 3: A10

Edge computing and 5G are two closely related technologies that have the potential to greatly enhance application performance and allow for the real-time processing of enormous volumes of data. While mobile edge computing lowers latency by moving processing capabilities inside the network and closer to the end user, 5G speeds can be up to ten times faster than those of 4G.

Benefits of Edge Computing

1. Cost Saving:

Businesses who first used the cloud for many of their apps may now be searching for a less expensive option after learning that the expenses for bandwidth were greater than anticipated. For them Edge Computing will be the great alternative

2. Fast Data Processing:

The capacity to process and store data more quickly enables more effective real-time applications, which are essential to businesses. Prior to the development of edge computing, a smartphone scanning a person’s face for facial recognition would have to process the facial recognition algorithm using a cloud-based service, which would take a long time. But in an edge computing architecture, these algorithms could run on local edge servers and even smartphones too.

3. Useful in many applications:

Virtual and augmented reality, self-driving cars, smart cities, and even building automation systems necessitate a high level of processing and response where edge computing works excellently.

4. New Features:

Edge computing can deliver previously unavailable capability. For example, a corporation can employ edge computing to process and analyze data at the edge, allowing it to be done in real time.

5. Enhances privacy protections and data security :

Data kept on centralized servers is more vulnerable to hacking since it contains more detailed information about individuals, places, and events. In contrast, additional data that would expose privacy in the event of a hack are not tampered with since edge computing creates, processes, and analyzes only the set of data needed at a given time.

6. Support AI/ML applications:

There is no doubting the growing importance of machine learning (ML) and artificial intelligence (AI) in contemporary computing. However, AI/ML applications operate by obtaining and analyzing massive amounts of data. When the data is stored on a centralized server, connectivity and latency problems may arise. Edge computing, on the other hand, makes it easier and faster for AI/ML applications to get results because data is processed near to the point of creation.

Edge Computing in Action — Use Cases

1. Manufacturing:

In an industrial setting, adaptive diagnostics can increase machine and equipment uptime while reducing service costs. Error codes produced by edge computing in conjunction with previous repair data might give technicians context, accelerating troubleshooting and repairs.

2. Smart Cities:

Public buildings and facilities can now be monitored for improved lighting, heating, and other systems. Cameras and signals can increase safety and traffic flow in applications for traffic control. Real-time edge computing will soon be most evident and dramatic in autonomous vehicles, where near-zero latency is essential.

3. HealthCare :

Wearable technology can keep track of variables like heart rate, temperature, and others and then send prescription reminders. To further improve security and privacy, edge computing enables developers to make sure sensitive data, such as medical images, does not leave the device.

4. Autonomous Vehicles:

In the platooning of truck convoys, a convoy of trucks follows closely behind one another to conserve fuel and ease traffic. Since the trucks will be able to interact with one another with extremely low latency thanks to edge computing, it will be possible to do away with the need for drivers in all but the front truck.

Drawback of Edge Computing

1. More Local Hardware:

While using Edge computing architecture we required more local hardware setup e.g. An IoT camera needs a built-in computer to send its raw video data to a web server, but in order to run its own motion-detection algorithms, it would need a much more advanced computer with more processing power. But the cost of hardware is falling, making the construction of smarter devices more affordable.

2. Network Bandwidth:

More computers are needed as more data is protected at the edge. The bandwidth needs to be expanded as a result. The balancing of network bandwidth is required for the implementation of edge computing.

3. Data Loss:

Although sorting through all of the data in a cloud data center can be time-consuming, you can rest easy knowing that it will be accessible when you need it thanks to the data’s central storage. Although edge computing operations reduce storage costs and space requirements, by accident an edge device could misinterpret or even destroy sensitive data.

Conclusion

Although there are advantages and disadvantages to edge computing, most IT professionals agree that it is here to stay, especially with the anticipated spread of 5G access. More consumers are accessing data through a variety of devices, which is fast changing edge computing and how it is used.

A good operating system is essential to run any device smoothly. When someone says operating system people immediately think of computers. Well, it is not completely their fault as the majority of them do not think about the mobile phone’s operating systems. People do not realize how important an operating system is in building a great mobile. A mobile phone’s operating system is a software or platform which enables other programs or software to run on it. An operating system is what specifies the features of a mobile phone. It determines how mobile should function when doing specific actions like texting, emailing, and so on. Moreover, it handles all the interactions between the software and the hardware. Before knowing different mobile OS, let us study some functions of an operating system.

Functions of OS

An operating system performs various tasks like memory management, process management/ scheduling, device management, file management. Also, keeps the system and programs safe and secure through authentication. A user ID and password decide the authenticity of the user. In addition to that, it also does Error detection, keeping a record of system performance, Communication between different software, etc.

Different Mobile Operating Systems:

1. Android

Android is the most popular mobile phone operating system right now. It is arguably the best mobile operating system that was ever created. Android was developed by Android Inc which was later bought by Google in the year 2005. Its operating system is designed based on the Linux kernel and some other open-source software. Android launched its first-ever device in 2008. Since then, android has been unstoppable with the latest version releasing every other year. The latest version of Android is Android 10.0 which does not have any name of a dessert like its predecessors.

2. Apple IOS

Apple IOS which was formerly known as iPhone OS is an operating system that was designed and developed by Apple Inc. It was specifically designed to only support the hardware that is used in iPhones. IOS was first released in the year 2007 which later extended its support to other Apple devices such as iPad and iPod touch. Its app store contains more than 2 million apps. iPhone iOS is known for its awesome security features and performance. It is the most reliable operating system present in the market.

3. Windows Mobile

We all know windows as the most widely used computer operating system in the world, but it also created its own mobile operating system in the name of Windows Phone mobile is an operating developed by Microsoft for smartphones. It was Microsoft’s big attempt to get its hands on the mobile phone market, but it was not that successful. It seemed a little difficult to operate for new users but soon its popularity started increasing. Its last release Windows 10 was the most loved as it removed its complications. You can find Microsoft Digital Asset Management Alternatives which are highly advanced DAM software that provides its services to businesses in midsize to large industries

4. BlackBerry OS

BlackBerry OS was developed by a Canadian company called BlackBerry Limited to use it for their brand of handheld mobiles. Just like Apple’s IOS, this operating system is specially designed for the devices manufactured by BlackBerry. This operating system is very robust as most of the time it was written in JAVA. It was specially designed for BlackBerry’s Research In Motion devices. Its ability to support trackball and trackwheel features made Blackberry devices more popular. BlackBerry OS is still one of the most secure platforms as its network is separate from other carriers. It was discontinued in the year 2013 when the company released BlackBerry 10 in 2013.

5. Symbian

Once upon a time, the Symbian operating system was the most popular operating system on the planet. It was developed in the 1980s by a company called PSION back then this OS was called EPOC. It was renamed SYMBIAN after PSION offered its platform to phone manufacturing companies. Nokia, Motorola, and SONY Ericsson are the popular mobile brands that used this operating system in their devices. Nokia used this OS more than any other mobile manufacturer. It also acquired SYMBIAN in 2008. The last version of SYMBIAN was released in 2012, later it was discontinued. Even today many of the phones made in China use its OS.

6. BADA

Samsung, the popular mobile phone brand has also created its own operating system called BADA. It was developed in 2009 with the intention of Samsung having its own mobile operating system. In 2010 Samsung released the Samsung wave which was its first phone that integrated BADA operating system. Samsung releases its phones with BADA operating system as wave series similar to its android powered galaxy series. BADA is considered to be one of the most developed operating systems that is available in the market. It was last used in the Samsung wave III.

7. KaiOS

KaiOS is another Linux based operating system that was created in the year 2017. It was developed by a US-based company called KaiOS Technologies. Its aim was to make smartphones more affordable. KaiOS wanted to achieve this goal by integrating 4G LTE, GPS and WiFi capabilities into non-touch phones. It also supports the installation of apps like Twitter and YouTube in non-touch phones. KaiOS is currently the third most popular OS after Android and IOS.
