Cyber-Security:Is It Really Required?????

As per the statistics,around 51% or 3.8 billion of the world population has internet access,there are more than 30 trillion sites on Google,and it’s gigantically increasing year on year!!!

However,it is more like a double-edged sword ,because along with usage and connectivity ,hacking,viruses,spams,leaking confidential data and other malicious uses are also intensifying at a great velocity.

As domain experts are getting more expertise for constructive purposes,the spiteful users are working on their expertise for destructive purposes.So an agile,continuous,smarter and impactful all-around approach is required.

What is cyber-security??

Cyber-security is the protection of internet-connected systems, including hardware, software and data, from cyber-attacks.
It is the the technique of protecting computers, networks, programs and data from unauthorized access or attacks that are aimed for exploitation.

Why Is It So Important??

 It is important because effective cyber-security reduces the risks of cyber attacks. Cyber-security is a high-demand but changing field. Since hackers are trying to find new ways to access, change, or delete sensitive information and extort money, users must be aware of cyber threats and comply with basic cyber-security principles.

Raising cyber-security awareness is one of the main strategies of data protection. Now many organizations are developing programs to train to battle with cyber threats. This not only helps them become skilled and forward-looking but also be as close as possible to in-demand and highly-paid jobs. Knowing how to secure a computer means being aware of how to secure the whole company and all its staff members.

Tools

Cyber-security is a very broad category which has numerous hardware and software technologies, and can be applied on any level, including personal, corporate or governmental devices or networks.

Passwords are a cyber-security tool that people encounter nearly every day. Other common cyber-security tools include:

  • Anti-virus/anti-malware software
  • Software patches
  • Firewalls
  • Two-factor authentication
  • Encryption

Common Threats

Keeping pace with cyber-security strategy and operations can be a challenge, particularly in government and enterprise networks where, in their most disruptive form, cyber-threats often take aim at secret, political, military or infrastructural assets of a nation, or its people. Some of the common threats are given below:

  • Cyber-terrorismis the disruptive use of information technology by terrorist groups to further their ideological or political agenda. This takes the form of attacks on networks, computer systems and telecommunication infrastructures.
  • Cyber-warfare involves nation-states using information technology to penetrate another nation’s networks to cause damage or disruption. In the U.S. and many other nations, cyber-warfare has been acknowledged as the fifth domain of warfare (following land, sea, air and space). Cyber-warfare attacks are primarily executed by hackers who are well-trained in exploiting the intricacies of computer networks, and operate under the auspices and support of nation-states. Rather than “shutting down” a target’s key networks, a cyber-warfare attack may intrude into networks to compromise valuable data, degrade communications, impair such infrastructural services as transportation and medical services, or interrupt commerce.
  • Cyber-espionage is the practice of using information technology to obtain secret information without permission from its owners or holders. Cyber-espionage is most often used to gain strategic, economic, political or military advantage, and is conducted using cracking techniques and malware.

Cyber-Crime

Cyber crime is the use of computers and networks to perform illegal activities such as spreading computer viruses, online bullying, performing unauthorized electronic fund transfers, etc. Most cyber-crimes are committed through the internet. Some cyber-crimes can also be carried out using mobile phones via SMS and online chatting applications.

Types Of Cyber-Crimes

  • The following list presents the common types of cyber-crimes:
  • Computer Fraud: Intentional deception for personal gain via the use of computer systems.
  • Privacy violation: Exposing personal information such as email addresses, phone number, account details, etc. on social media, websites, etc.
  • Identity Theft: Stealing personal information from somebody and impersonating that person.
  • Sharing copyrighted files/information: This involves distributing copyright protected files such as eBooks and computer programs etc.
  • Electronic funds transfer: This involves gaining an un-authorized access to bank computer networks and making illegal fund transfers.
  • Electronic money laundering: This involves the use of the computer to launder money.
  • ATM Fraud: This involves intercepting ATM card details such as account number and PIN numbers. These details are then used to withdraw funds from the intercepted accounts.
  • Denial of Service Attacks: This involves the use of computers in multiple locations to attack servers with a view of shutting them down.
  • Spam: Sending unauthorized emails. These emails usually contain advertisements. 

So Who Are Hackers???

Hacker is a person who finds and exploits the weakness in computer systems and/or networks to gain access. Hackers are usually skilled computer programmers with knowledge of computer security.

Hackers are classified according to the intent of their actions.

The following list classifies hackers according to their intent.

SD
Ethical Hacker (White hat): A hacker who gains access to systems with a view to fix the identified weaknesses. They may also perform penetration testing and vulnerability assessments.
Cracker (Black hat): A hacker who gains unauthorized access to computer systems for personal gain. The intent is usually to steal corporate data, violate privacy rights, transfer funds from bank accounts etc.
Grey hat: A hacker who is in between ethical and black hat hackers. He/she breaks into computer systems without authority with a view to identify weaknesses and reveal them to the system owner.
Script kiddies: A non-skilled person who gains access to computer systems using already made tools.
Hacktivist: A hacker who use hacking to send social, religious, and political, etc. messages. This is usually done by hijacking websites and leaving the message on the hijacked website.
Phreaker: A hacker who identifies and exploits weaknesses in telephones instead of computers.

Some Trends In Cyber-Security

1.Blockchain technology originated through Bitcoins in 2008,but from 2008 it’s true momentum has got realized in the IT domain and now it is being used to safeguard data,preventing potential frauds and scams,protecting data from unwanted uses.

2.Firewall is the evergreen solution in cyber-security.It is a network security system that authenticates incoming and outgoing network crowd based on predefined security rules.

3.Artificial intelligence and Machine Learning can understand past events and predict future events on cyber-security threats,It can be used to detect malware and cyber attacks,proactive measures can be taken.

4.Sandbox technology is a security mechanism for bifurcating the running programs,with an intention to mitigate system failures or software vulnerabilities from unrolling.It has become a popular method for identifying and safeguarding against malware infections.

5.Cloud computing as everything is managed on clouds or offsite,the risks are reduced to a great extend,there is no data breach on spaces like AWZ, Azure,GCP and they act as the benchmark in safeguarding data and enjoy the title of the most secured firm platform.
