ABSTRACT

Cyber Security plays an important role in the field of Information Technology. Securing information has become one of the biggest challenges in the present day. Whenever we think about cybersecurity the first thing that comes to our mind is ‘cyber crimes’ which are increasing immensely day by day. Various Governments and companies are taking many measures in order to prevent these cybercrimes. Besides various measures, cybersecurity is still a very big concern to many. This paper mainly focuses on challenges faced by cybersecurity on the latest technologies. It also focuses on the latest about cybersecurity techniques, ethics, and trends changing the face of cybersecurity.

INTRODUCTION


Today man is able to send and receive any form of data may be an e-mail or an audio or video just by the click of a button but did he ever think how securely his data-id a transfer or sent to the other person safely without any leakage of information?? The answer lies in cybersecurity. Today Internet is the fastest growing infrastructure in everyday life. In today’s technical environment many latest technologies are changing the face of mankind.

But due to these emerging technologies, we are unable to safeguard our private information in a very effective way and hence these days cyber crimes are increasing day by day. Today more than 60 percent of total commercial transactions are done online, so this field requires high quality of security for transpar and best transactions. Hence cybersecurity has become the latest issue. The scope of cybersecurity is not just limit to securing the information in the IT industry but also to various other fields like cyberspace etc.


Even the latest technologies like cloud computing, mobile computing, E-commerce, net banking, etc also need a high level of security. Since these technologies hold some important information regarding a person their security has become a must thing. Enhancing cybersecurity and protecting critical information infrastructures are essential to each nation’s security and economic wellbeing. Making the Internet safer (and protecting Internet users) has become integral to the development of new programs. As day by day technology is playing a major role in a person’s life the cyber crimes also will increase along with technological advances.

CYBERCRIME

Cybercrime is a term for any illegal activity that uses a computer as its primary means of commission and theft. The U.S. Department of Justice expands the definition of cybercrime to include any illegal activity that uses a computer for the storage of evidence. The growing list of cybercrimes include crimes that have been made possible by computers, such as network intrusions and the dissemination of computer viruses, as well as computer-based variations of existing crimes, such as identity theft, stalking, bullying, and terrorism which have become a major problem to people and nations.

Usually in common man’s language cybercrime may be defined as a crime commit use a computer and the internet to steal a person’s identity or sell contraband or stalk victims or disrupt operations with malevolent. technology and healthcare executives nationwide, Silicon Valley Bank find that companies believe cyberattacks are a serious threat to both their data and their business continuity.

SOME POINTS
  • 98% of companies are maintaining or increasing their cybersecurity resources and of those, half are increasing resources devoted to online attacks this year
  • The majority of companies are preparing for when, not if, cyber-attacks occur
  • Only one-third are completely confident in the security of their information and even less confident about the security measures of their business partners.

There will be new attacks on Android operating system-based devices, but they will not be on a massive scale. The fact tablets share the same operating system as smartphones mean they will be soon targeted by the same malware as those platforms. The number of malware specimens for Macs would continue to grow, though much less than in the case of PCs. Windows 8 will allow users to develop applications for virtually any device (PCs, tablets, and smartphones) running Windows 8, so it will be possible to develop malicious applications like those for Android, hence these are some of the predicted trends in cybersecurity.

CYBER SECURITY


Privacy and security of the data will always be the top security measures that any organization takes care of. We are presently living in a world where all the information is maintained in a digital or a cyber form. Social networking sites provide a space where users feel safe as they interact with friends and family. In the case of home users, cyber-criminals would continue to target social media sites to steal personal data. Not only social networking but also during bank transactions a person must take all the required security measures.

The above Comparison of Cyber Security Incidents reported to Cyber999 in Malaysia from January–June 2012 and 2013 clearly exhibits the cybersecurity threats. As crime is increasing even the security measures are also increasing. According to the survey of U.S.

TRENDS CHANGING CYBERSECURITY

Here mentioned below are some of the trends that are having a huge impact on cybersecurity.

1. Web servers:

The threat of attacks on web applications to extract data or to distribute malicious code persists. Cybercriminals distribute their malicious code via legitimate web servers they’ve compromised. But data-stealing attacks, many of which get the attention of the media, are also a big threat. Now, we need a greater emphasis on protecting web servers and web applications. Web servers are especially the best platform for these cybercriminals to steal data. Hence one must always use a safer browser, especially during important transactions in order not to fall prey to these crimes.

2. Cloud computing and its services

These days all small, medium, and large companies are slowly adopting cloud services. In other words, the world is slowly moving towards the clouds. This latest trend presents a big challenge for cybersecurity, as traffic can go around traditional points of inspection. Additionally, as the number of applications available in the cloud grows, policy controls for web applications and cloud services will also need to evolve in order to prevent the loss of valuable information. Though cloud services are developing their own models still a lot of issues are being brought up about their security. Cloud may provide immense opportunities but it should always be noted that as the cloud evolves so as its security concerns increase.

3. APT’s and targeted attacks

APT (Advanced Persistent Threat) is a whole new level of cyber crimeware. For years network security capabilities such as web filtering or IPS have played a key part in identifying such targeted attacks (mostly after the initial compromise). As attackers grow bolder and employ more vague techniques, network security must integrate with other security services in order to detect attacks. Hence one must improve our security techniques in order to prevent more threats coming in the future.

4. Mobile Networks

Today we are able to connect to anyone in any part of the world. But for these mobile networks security is a very big concern. These days firewalls and other security measures are becoming porous as people are using devices such as tablets, phones, PCs, etc all of which again require extra securities apart from those present in the applications used. We must always think about the security issues of these mobile networks. Further mobile networks are highly prone to these cybercrimes a lot of care must be taken in case of their security issues.

5.IPv6: New internet protocol

IPv6 is the new Internet protocol that is replacing IPv4 (the older version), which has been a backbone of our networks in general and the Internet at large. Protecting IPv6 is not just a question of porting IPv4 capabilities. While IPv6 is a wholesale replacement in making more IP addresses available, there are some very fundamental changes to the protocol which need to be considered in security policy. Hence it is always better to switch to IPv6 as soon as possible in order to reduce the risks regarding cybercrime.

6.Encryption of the code

Encryption is the process of encoding messages (or information) in such a way that eavesdroppers or hackers cannot read them. In an encryption scheme, the message or information is encrypted using an encryption algorithm, turning it into an unreadable ciphertext. This is usually done with the use of an encryption key, which specifies how the message is to be encoded. Encryption at the very beginning level protects data privacy and its integrity. But more use of encryption brings more challenges in cybersecurity. Encryption is also used to protect data in transit, for example, data being transferred via networks (e.g. the Internet, e-commerce), mobile telephones, wireless microphones, wireless intercoms, etc. Hence by encrypting the code one can know if there is any leakage of information.
Hence the above are some of the trends changing the face of cybersecurity in the world. The top network threats are mentioned below

The above pie chart shows the major threats for networks and cybersecurity.

ROLE OF SOCIAL MEDIA IN CYBERSECURITY

As we become more social in an increasingly connected world, companies must find new ways to protect personal information. Social media plays a huge role in cybersecurity and will contribute a lot to personal cyber threats. Social media adoption among personnel is skyrocketing and so is the threat of attack. Since social media or social networking sites are almost used by most of them every day it has become a huge platform for cybercriminals for hacking private information and stealing valuable data.


In a world where we’re quick to give up our personal information, companies have to ensure they’re just as quick in identifying threats, responding in real-time, and avoiding a breach of any kind. Since people are easily attracted by these social media the hackers use them as bait to get the information and the data they require. Hence people must take appropriate measures especially in dealing with social media in order to prevent the loss of their information.

The ability of individuals to share information with an audience of millions is at the heart of the particular challenge that social media presents to businesses. In addition to giving anyone the power to disseminate commercially sensitive information, social media also gives the same power to spread false information, which can be just being as damaging. The rapid spread of false information through social media is among the emerging risks identified in the Global Risks 2013 report. Though social media can be use for cyber crimes these companies cannot afford to stop using social media as it plays an important role in the publicity of a company.

Instead, they must have solutions that will notice all of the threats in order to fix them before any real damage is done. However, companies should understand this and recognize the importance of analyzing the information especially in social conversations and provide appropriate security solutions in order to stay away from risks. One must handle social media by using certain policies and the right technologies.

CYBERSECURITY TECHNIQUES

1. Access control and password security

The concept of user name and password has been a fundamental way of protecting our information. This may be one of the first measures regarding cybersecurity.

2. Authentication of data

The documents that we receive must always be authenticated be before downloading that is it should be checked if it has originated from a trusted and a reliable source and that they are not altered. Authenticating these documents is usually done by the anti-virus software present in the devices. Thus a good anti-virus software is also essential to protect the devices from viruses.

3. Malware scanners

This is software that usually scans all the files and documents present in the system for malicious code or harmful viruses. Viruses, worms, and Trojan horses are examples of malicious software that are often groupe together and refer to as malware.

4. Firewalls

A firewall is a software program or piece of hardware that helps screen out hackers, viruses, and worms that try to reach your computer over the Internet. All messages entering or leaving the Internet pass through the firewall present, which examines each message and blocks those that do not meet the specified security criteria. Hence firewalls play an important role in detecting the malware.

5. Anti-virus software

Antivirus software is a computer program that detects, prevents, and takes action to disarm or remove malicious software programs, such as viruses and worms. Most antivirus programs include an auto-update feature that enables the program to download profiles of new viruses so that it can check for the new viruses as soon as they are discover. Anti-virus software is a must and a basic necessity for every system.

Techniques on cyber security

CYBER ETHICS

Cyberethics is nothing but the code of the internet. When we practice these cyber ethics there are good chances of us using the internet in a proper and safer way. The below are a few of them:

  • DO use the Internet to communicate and interact with other people. Email and instant messaging make it easy to stay in touch with friends and family members, communicate with work colleagues, and share ideas and information with people across town or halfway around the world
  • Don’t be a bully on the Internet. Do not call people names, lie about them, send embarrassing pictures of them, or do anything else to try to hurt them.
  • Internet is consider as the world’s largest library with information on any topic in any subject area, so using this information in a correct and legal way is always essential.
  • Do not operate other accounts using their passwords.
  • Never try to send any kind of malware to other’s systems and make them corrupt.
  • Never share your personal information with anyone as there is a good chance of others misusing it and finally you would end up in a trouble.
  • When you’re online never pretend to the other person, and never try to create fake accounts on someone else as it would land you as well as the other person into trouble.
  • Always adhere to copyrighted information and download games or videos only if they are permissible.

The above are a few cyber ethics one must follow while using the internet. We always teach proper rules from our very early stages the same here we apply in cyberspace.

CONCLUSION

Computer security is a vast topic that is becoming more important because the world is becoming highly interconnected. with networks being used to carry out critical transactions. Cybercrime continues to diverge down different paths with each New Year that passes and so does the security of the information.

The latest and disruptive technologies, along with the new cyber tools and threats that come to light each day, are challenging organizations with not only how they secure their infrastructure. but how they require new platforms and intelligence to do so. There is no perfect solution for cyber crimes but we should try our level best to minimize them in order to have a safe and secure future in cyberspace.
