IT security, cybersecurity as well as computer security is the defence of networks and computer systems from any damage to electronic data, software, hardware and misdirection or disruption. This field is becoming more significant because of the upsurge of dependency in wireless networks like Wi-Fi and Bluetooth, the internet as well as computer systems, because of the rapid increase of IoT and smart devices. Besides, there are various categories like end-user education, business continuity as well as disaster recovery, operational security, information, network and application securities.

End-user education

This usually addresses the unpredictable factor of cybersecurity, such that whoever could accidentally develop viruses to other security systems by lack of following proper security practices. Further, educating the users not to plug-in the undefined USB drives, to eliminate malicious mail attachments as well as various predominant lessons are essential for any organisations security.

Business continuity as well as disaster recovery

This actually defines how organization reacts to incidents regarding cyber security or other incident, which causes operation loss or data loss. The disaster recovery policy addresses how organizations restore its information and operation for returning same operating capacities. Besides, the business continuity is known as planning organizations at the same time attempting to function without some sources.

Operational security

The operational security incorporates the decisions and process to handle data as well as protect data assets. Further, the users have permission while they assess networks and procedures, thereby determining where and how the data is shared or stored. Information security. The information security defends the privacy and integrity of data in transit as well as in storage.

Application security

The application security concentrates on preserving the devices as well as software from threats. Further, compromised applications can give access to data. A successful security origins in a state of designing, before it is programmed and implemented.

Network security

The network security is generally known as practice of protecting network of a computer from the intruders, if they were targeted by any malwares or attackers.

Now, to answer the particular question, “why cyber security is essential?”

In recent years, the cyber security is considered as a top priority for any organization. The executives actually knows, cyber security is perilous for business process and operation. Further, the significance of cyber security is initial theme while planning as well as allocating. Several companies try to get best available Cyberdefenses. In addition to that, just the implementation of security tool such as antivirus and firewall is not effective in today’s world.

Statistics of cyber security

It is important to understand cyber security’s magnitude before we answer to the previous question. The statistics, which are mentioned below depicted, cybercrimes are widespread as well as they are necessary for adopting potential cyber security measures. The damages from cybercrimes has resulted over six trillion dollars in the year 2011. Further, some reports have mentioned that Vice president of Cisco has denoted that, coders might produce about one hundred and eleven billion codes for software development each and every year. As such, this has introduced huge amount of vulnerabilities.

Technology changes the landscape

Various new technologies have developed in past two decades. These technologies redefined the landscape, including business operations, storage and data processing as well as the communication channel. For instance, the social media networks such Twitter and Facebook were frequently utilized for communicating the launch of any products or various other information instantaneously to billions of customers. But when comparing the same in past few years, radio and television were prime means for advertising. Besides, today, every business use cloud services, thus cyber security is only means for protecting the data in cloud.

Cyber threats types

The following are the threats, encountered by cyber security:

• Cyber terrorism
• Cyber attack
• Cyber crime

Cyber terrorism generally destabilizes the electronic systems for causing fear or panic, whereas cyber-attack frequently encompasses the gathering of political motivated-information. Meanwhile cyber-crime consisted group of actors or single actors to target the systems for causing disruption. Under these, how malicious actors can control the systems? The following are certain common techniques utilized for threatening cyber security.

Malwares

Malwares are referred to the malicious software, in which the hackers or cyber criminals developed a software for damaging or disrupting computers. Moreover, they are frequently spread through mail attachments or through unknown contact cards. In addition to that, malwares might be utilized by the cyber criminals for money purposes or also political encouraged cyber-attacks. The following are types of malware,

• Trojans
• Virus
• Botnets
• Adware
• Ransomware
• Spyware

Trojans are known as malware, which are disguised as genuine software. Here, the cyber criminals ingeniously trick the users and they collect data or cause damage. Virus is known as self-duplicating program, which itself attaches to a genuine file or document and spreads to entire system, thereby infecting every files and data with malicious codes. Botnets are considered as infected computer’s network, utilized by the cyber criminals for performing online tasks without the permission of users. Adware usually advertises the software that could be utilized for spreading malware. Ransomware is also a malware that locks the files and data of users, and threatens the users to pay huge amount of money or it erases entire data. Spyware is a program, which secretly records the activities of users, thus the cyber criminals’ could utilize these recorded information. For instance, spyware can also capture and record the details of credit cards.

The following are certain tips and tricks for protecting ourselves against the cyber-attacks.

Keep the operating system and software always up to date, the security patch updates will protect our system from virus. Make sure your system has genuine anti-virus, using genuine paid anti-virus software will benefit a lot. Although, there are several anti-virus software available for free, they may or may not be safe. Always put up a stronger password, and also make sure that the passwords cannot be guessed. Most importantly, don’t open any mails from unknown contacts, since they could also be virus. Also, don’t click any links that are attached with e-mails or unknown websites, because this is most common way for virus spread. In addition to that, stop using unsecure and unknown free Wi-Fi in public places, as these Wi-Fi networks will leave us vulnerable to MITM attacks (Man in the Middle).
