Causes of CyberCrime and Preventive Measures

By Ravi Bandakkanavar | June 10, 20170 Comment
We are living in the modern era based on the technology. Our daily life depends on it, live with it. So, nowadays the internet is a common name known to all. It is a pool of Information. Everything we need, any information regarding anything we can find on the internet. So, people are using and depending on it more and more. As internet usage is increasing day by day, it makes the world small; people are coming closer. Rapid technological growth and developments have provided vast areas of new opportunity and efficient sources for organizations of all sizes. It has become now a national asset, the whole national security is also depending on it. But these new technologies have also brought unprecedented threats with them a cyber crime. Cybercrime is a crime in which a computer is used for the crime like hacking, spamming, phishing etc.

Introduction to Cybercrime:

Cyber criminals use internet and computer technology to hack user’s personal computers, smartphone data, personal details from social media, business secrets, national secrets etc. Criminals who perform these illegal activities through the internet are called – Hackers. Though law enforcement agencies are trying to tackle this problem, it is growing regularly and many people have become victims of identity theft, hacking and malicious software. One of the best ways to stop these criminals and protect sensitive information is by making use of inscrutable security that uses a unified system of software and hardware to authenticate any information that is accessed over the Internet. Let’s find out more about cyber crimes.

Causes of Cybercrime:

Cyber criminals always opt an easy way to make big money. They target rich people or rich organizations like banks, casinos and financial firms where a huge amount of money flows daily and hack sensitive information. Catching such criminals is difficult. Hence, that increases the number of cyber-crimes across the globe. Computers are vulnerable, so laws are required to protect and safeguard them against cyber criminals. We could list following reasons for the vulnerability of computers:

Easy to access – The problem behind safeguarding a computer system from unauthorized access is that there are many possibilities of breach due to the complex technology. Hackers can steal access codes, retina images, advanced voice recorders etc. that can fool biometric systems easily and bypass firewalls can be utilized to get past many security systems.
Capacity to store data in comparatively small space – The computer has the unique characteristic of storing data in a very small space. This makes it a lot easier for the people to steal data from any other storage and use it for own profit.
Complex – The computers run on operating systems and these operating systems are programmed of millions of codes. The human mind is imperfect, so they can do mistakes at any stage. The cyber criminals take advantage of these gaps.
Negligence – Negligence is one of the characteristics in human conduct. So, there may be a possibility that protecting the computer system we may make any negligence which provides a cyber-criminal the access and control over the computer system.
Loss of evidence – The data related to the crime can be easily destroyed. So, Loss of evidence has become a very common & obvious problem which paralyzes the system behind the investigation of cyber-crime.
Types of CyberCrimes

There are many types of cyber-crimes and the most common ones are explained below:

Hacking: It is a simple term that defines sending an illegal instruction to any other computer or network. In this case, a person’s computer is hacked so that his personal or sensitive information can be accessed. The criminal uses a variety of software to crack a person’s computer and the person may not be aware that his computer has been accessed from a remote location. Often, government websites are a hot target for hackers because it helps them gain notoriety which is further fuelled by aggressive media coverage. This is different from ethical hacking which is used by many organization to check their Internet security protection.
Child pornography and Abuse: The internet is being highly used to abuse children sexually worldwide. This is also a type of cyber-crime wherein criminals solicit minors via chat rooms for the purpose of child pornography. The Cybersecurity department of every nation is spending a lot of time monitoring chat rooms frequented by children with the hopes of reducing and preventing child abuse and soliciting.
Piracy or Theft: This crime occurs when a person violates copyrights and downloads music, movies, games, and software. There are even peer sharing websites which encourage software piracy and many of these websites are now being targeted by the FBI. Today, the judicial system is addressing this cyber crime and there are laws that prevent people from illegal downloading. Film producers and directors often become victims of this crime.
Cyber Stalking: This is a kind of online harassment wherein the victim is subjected to a barrage of online messages and emails. Typically, these stalkers know their victims and instead of resorting to offline stalking, they use the Internet to stalk. However, if they notice that cyber stalking is not having the desired effect, they begin offline stalking along with cyber stalking to make the victims’ lives more miserable.
Cyber Terrorism: Cyber terrorism, also known as information wars, can be defined as any act of Internet terrorism which includes deliberate and large-scale attacks and disruptions of computer networks using computer viruses, or physical attacks using malware, to attack individuals, governments and organizations. The goal of terrorism is to create a feeling of terror in the minds of the victims. Keeping this concept in mind, it becomes easier to differentiate cyber-attacks for a financial, or egotistical, gain from acts of cyber terrorism. Cyber terrorists operate with the goal of damage and destruction at the forefront of their activities.
Identity Theft: This has become a major problem with people using the Internet for cash transactions and banking services. In this cyber-crime, a criminal accesses data about a person’s bank account, credit cards, Social Security, debit card and other sensitive information to siphon money or to buy things online in the victim’s name. It can result in major financial losses for the victim and even spoil the victim’s credit history.
Computer vandalism: Computer vandalism is a type of malicious behavior that involves damages computers and data in various ways and potentially disrupting businesses. Typical computer vandalism involves the creation of malicious programs designed to perform harmful tasks such as erasing hard drive data or extracting login credentials. Computer vandalism differs from viruses, which attach themselves to existing programs.
Malicious Software: These are Internet-based software or programs that are used to disrupt a network. The software is used to gain access to a system to steal sensitive information or data or causing damage to software present in the system.
How to tackle CyberCrime

To tackle cybercrime effectively, establish multidimensional public-private collaborations between law enforcement agencies, the information technology industry, information security organizations, internet companies and financial institutions. Unlike the real world, Cyber criminals do not fight one another for supremacy or control. Instead, they work together to improve their skills and even help out each other with new opportunities. Hence, the usual methods of fighting crime cannot be used against cyber criminals.

The best way to go about is using the solutions provided by Cross-Domain Solutions. This allows organizations to use a unified system comprising of software and hardware that authenticates both manual and automatic transfer and access of information when it takes places between different security classification levels. This allows seamless sharing and access of information within a specific security classification, but cannot be intercepted by or advertently revealed to the user who is not part of the security classification. This helps to keep the network and the systems using the network safe.

Use Strong Passwords: Use the different password and username combinations for different accounts and resist the temptation to write them down.
Be social media savvy: Be sure to keep your social networking profiles (Facebook, Twitter, YouTube, etc.) are set to private. Be sure to check your security settings. Be careful of what information you post online. Once it is on the Internet it is there forever.
Secure your Mobile Devices: Many people are not aware that their mobile devices are also vulnerable to malicious software, such as computer viruses and hackers. Be sure to download applications only from trusted sources. It is also crucial that you keep your operating system up-to-date. Be sure to install anti-virus software and to use a secure lock screen as well. Otherwise, anyone can access all your personal information on your phone if you misplace it or even set it down for a few moments. Someone could even install malicious software that could track your every movement through your GPS.
Protect your data: Protect your data by using encryption for your most sensitive files such financial records and tax returns.
Protect your identity online: When it comes to protecting your identity online it is better to be too cautious than not cautious enough. It is critical that you be cautious when giving out personal ID such as your name, address, phone number and/or financial information on the Internet. Be certain to make sure websites are secure when making online purchases, etc. This includes enabling your privacy settings when using/accessing social networking sites.
Keep your computer current with the latest patches and updates: One of the best ways to keep attackers away from your computer is to apply patches and other software fixes when they become available. By regularly updating your computer, you block attackers from being able to take advantage of software flaws (vulnerabilities) that they could otherwise use to break into your system.
Protect your computer with security software: Several types of security software are necessary for basic online security. Security software essentials include firewall and antivirus programs. A firewall is usually your computer’s first line of defense. It controls who and what can communicate with your computer online. You could think of a firewall as a sort of “policeman” that watches all the data attempting to flow in and out of your computer on the Internet, allowing communications that it knows are safe and blocking “bad” traffic such as attacks from ever reaching your computer.
Call the right person for help: Try not to panic if you are a victim. If you encounter illegal online content, such as child exploitation, or if you suspect a cybercrime, identity theft or a commercial scam, just like any other crime report this to your local police. There are many websites to get help on cybercrime. To name few http://www.cybercrimehelpline.com http://www.cyberpolicebangalore.nic.in, http://www.cybercellmumbai.gov.in

5G Wireless Technology

By Ravi Bandakkanavar | March 30, 201727 Comments
5G simply refers to the next and newest mobile wireless standard based on the IEEE 802.11ac standard of broadband technology. We can say that – 5G Wireless Technology denotes the proposed next major phase of mobile telecommunications standards beyond the current 4G standards. Rather than faster Internet connection speeds, 5G planning aims at a higher capacity than current 4G, allowing a higher number of mobile broadband users per area unit, and allowing consumption of higher or unlimited data quantities in gigabyte per minute and user. This would make it feasible for a large portion of the population to consume high-quality streaming media many hours per day on their mobile devices, also when out of reach of wifi hotspots. 5G research and development also aim at improved support of machine to machine communication, also known as the Internet of things, aiming at lower cost, lower battery consumption, and lower latency than 4G equipment.

The main aim of 5G research and development is to provide a higher speed of internet at a lesser cost, to reduce battery drainage, lower latency, to increase the security and connectivity for a large community.

High & increased peak bit rate (Up to 10Gbps connections to endpoints in the field)
Efficient use of energy in devices
Larger data volume per unit area (i.e. high system spectral efficiency)
High capacity to allow more devices connectivity concurrently and instantaneously (100percent coverage)
More bandwidth
Lower battery consumption
Better connectivity irrespective of the geographic region, in which you are
Larger number of supporting devices (10 to 100x number of connected devices)
Lower cost of infrastructural development
Higher reliability of the communications (One millisecond end-to-end round trip delay)
With a huge array of innovative features, now your smartphone would be more parallel to the laptop. You can use broadband internet connection; other significant features that fascinate people are more gaming options, wider multimedia options, connectivity everywhere, zero latency, faster response time, and high-quality sound and HD video can be transferred to another cell phone without compromising the quality of audio and video.

5G Wireless Technology

5G Wireless Technology Uses UWB (Ultra Wide Band) networks with higher Band Width at low energy levels. Band Width is of 4000 Mbps, which is 400 times faster than today’s wireless networks. It uses a smart antenna and CDMA (Code Division Multiple Access). 5G will be the single unified standard of different wireless networks, including LAN technologies, LAN/WAN, WWWW- World Wide Wireless Web, unified IP & seamless combination of broadband. It follows Master Core technology to be operated into parallel multimode including all IP network mode and 5G network mode. In this mode (as shown in the image given below), it controls all network technologies of RAN and Different Access Networks (DAT). Any service mode can be opened under 5G New Deployment Mode as World Combination Service Mode (WCSM). WCSM is a wonderful feature of this technology; for example, if a teacher writes on the white board in a country – it can be displayed on another white board in any other part of the world besides conversation and video. Further, new services can be easily added through parallel multimode service.

It is expected that the implementation of 5G Wireless Technology is about to take four years more from now. As to make it usable for the people o the third world we need more time. We need more time to develop its functionality. We need more research on its users and security. The speed, it is promised to serve is hard to achieve and we need high infrastructure for 5G wireless technology Deployment. So, we can see there are various challenges to overcome. So we can expect its deployment in 2020. Currently, the United States and South Korea are leading in the implementation of 5G. The South Korean government has reportedly invested $1.5billion in 5G research and promised a trial of 5G in 2017.

5G Wireless Technology is more intelligent technology, which will interconnect the entire world without limits. It is designed to provide unbelievable and extraordinary data capabilities, unhindered call volumes, and vast data broadcast. Our world would have universal and uninterrupted access to information, communication, and entertainment that will open a new dimension to our lives and will change our lifestyle meaningfully.

Moreover, governments and regulators can use this technology as an opportunity for the good governance and can create healthier environments, which will definitely encourage continuing investment in 5G, the next generation technology.

India is also advancing towards 5g though the implementation of 4G and 3G is still under process. The Indian Institute of Technology, Hyderabad (IITH), is getting ready to exhibit the first Cloud RAN prototype for 5G. This will be much faster than the existing 4G. The faculty and students of IITH started working on the 5G project about two years ago and now it has become a reality. “Cloud RAN prototype for 5G with interference free communications is one of the first prototypes in the world. To understand it in common man’s language, this will allow downloading a cinema from the web within eight to 10 seconds. The usage of data and communication in the society will have a direct correlation with the increase of gross domestic product of the country. We are already witnessing the game change brought by 4G technology and the impact of 5G will be multiple,” says associate professor Kiran Kuchi of the Department of Electrical Engineering.
