Cybersecurity
Internet security, including cybersecurity, hardware, software, and data, is connected to the system.
What is Cyber Security?
Cyber Security is the practice of protecting systems, networks, and programs from digital attacks. These attacks are usually intended for access, change, or destruction of sensitive information; Withdraw money from users; Or disrupt normal business processes.
Implementing effective cybersecurity measures is especially challenging today because there are more devices than people, and the attackers are becoming more innovative.
It is also known as Information Technology Security or Electronic Information Security.
Types of Cybersecurity
This term applies in a variety of references, from business to mobile computing, and can be divided into some general categories.
1) Network Security:
Network Security is the practice of securing computer networks with intruders, whether targeted attackers or opportunistic malware.
2) Application Security:
The application focuses on keeping security, software, and devices free of danger. A compromised application can provide access to the data designed for security. Successful security begins in the design step before any program or device is deployed.
3) Information Security:
Information security protects the integrity and privacy of data, both in storage and transit.
4) Operational Security:
Operational security includes procedures and decisions for handling data assets and their security. While accessing a network, the user's permissions and the procedures for determining how and where the data can be stored or shared, all come under this security.
5) Disaster Recovery and Business Continuity:
This security defines how an organization responds to the cybersecurity incident or any other event that causes the loss of operation or data. The Disaster Recovery Policy states that the organization brings its operations and information back to the same operating capacity as was before the attack. The continuity of business is the plan that the organization comes back in an attempt to operate without some resources.
6) End-User Education:
End-user education addresses the most unexpected cyber-security factor: people. Anyone can accidentally bring a virus to the security system by failing to follow good security practices. For the security of any organization, users should learn to remove suspicious email attachments, not plug in an unknown USB drive, and various other important lessons.
Challenges of Cyber Security-
For effective cybersecurity, an organization needs to coordinate its efforts in its entire information system. All of the following include Cyber Elements:
Network security
Application security
End Point Security
Data security
Identity management
Database and Infrastructure Security
Cloud security
Mobile security
Disaster Recovery / Business Continuity Plan
End-user education
The toughest challenge in cybersecurity is the increasing nature of self-risk risks. Traditionally, the organization and government have focused on most of their cybersecurity resources on the security of more layers so that only their most important system components can be protected and protected against known threats.
Today, this view is insufficient, because the threats have become advanced and can change faster than the Organizations. As a result, advisory organizations promote a more active and adaptive approach to cybersecurity. Therefore, the Security Institute issues guidelines in its risk assessment framework, in contrast to traditional surveillance-based models, recommend continuous monitoring and real-time assessment, a shift toward a data-focused approach to security.
Three columns of cybersecurity1) People:
2) Processes:
Processes are important in defining the activities, roles, and documentation used in the organization to reduce the risks of organizational information. Cyber hazards change quickly, so continuous review is needed to be able to optimize processes with them.
3) Technology:
By identifying cyber risks that face your organization, you can begin to see where you have to control, and what techniques you need to do this. The technology can be deployed to prevent or minimize the impact of cyber risks, which comeRisk risk assessment and you depend on acceptable levels of risk.
Why is Cyber Security Important?
So what makes Cyber Security so important? Most companies today are browsing more and more information on computer databases. When you are connected to the internet individually or do shopping with your credit, not only is your information at risk but it is also at risk of denting it at any time of the day.
Government, military, financial institutions, various corporations, hospitals, and many other business processes do and store your information on their network. While these organizations use sophisticated security tactics, there is no way to guarantee that your information is always safe.
In the coming years, using new technologies and intentions will lead to more advanced cyber attacks. There will be a dramatic increase in the availability of ransomware and malware on the Dark Web. It does not matter to anyone, no matter how technical their knowledge is, they will not be allowed to start a cyber attack easily and quickly.
Nevertheless, due to the loss of cyber attacks in the past, there is now more awareness about cyber attacks and better cyber security measures are also needed between all types of organizations.
It will serve as a motivation for cybercriminals to work on stage for new and more sophisticated attacks in the future, to promote their game.
Cybersecurity is a continuous process because of the risk. The security system is constantly updated in an effort to thwart the increasing amount of cyber-attacks and complexity.
i) Cost of data breaches is increasing:
With the EU GDPR (General Data Protection Regulation) now implemented, organizations may have to face up to 20 million euros or up to 4% of annual global business for some violation. There is also a non-financial cost to consider, such as the loss of reputable damage and customer trust.
ii) Cyber attacks are becoming increasingly sophisticated:
In order to take advantage of vulnerabilities in social engineering, malware, and ransomware (such as in the case of Petya, Vasari, and Notepatia), sometimes using increasing strategy, cyber attacks with the attackers have become more sophisticated.
Types of Cybersecurity Threats
1) Viruses
Viruses are a type of malware program designed specifically to harm victims' computers. Viruses can self-replicate under the right conditions and can infect the computer system without the user's permission or knowledge.
2) Identity Theft
This is a type of cyber security threat that involves the use of that information to steal the personal information of victims from social media websites such as Facebook, Instagram, etc. and to create a picture of victims. If enough sensitive information is collected, then it may allow cyber crime to pretend like you in some way.
3) Password Attacks
This is a type of cyber security threat that involves the hacking attempt by hackers to crack the user's password. With the help of hacking tools, hackers can enter many passwords to obtain the credentials of the victim's account and to gain access.
4) Spyware and Keyloggers
Spyware and Keyloggers collect user information, passwords, browsing the history, and then direct them to their creator (hackers) who can sell or distribute this personal information to a third party. Hackers can also use that information to steal money from the victim's bank account.
5) Adware
Adware is a group of malware that is known to generate pop-ups. If the user downloads that additional software, it can either delete or steal your data. Some of these pop-up messages can also be used to make your computer screen bombs with just unwanted information such as ads.
6) Trojans
Trojans are a type of malware program that presents itself as harmless or useful software. Trojans can cause many types of malicious activities, including the download of malicious programs on a victim's computer, deleting files or stealing, and providing hackers with unauthorized access to victims' computers.
7) Ransomware
Unlike many other types of cyber attacks, ransomware attacks inform victims of exploitation and also gives instructions on how to recover them (usually demanding payment for recovery). To prevent a crack by law enforcement, hackers who are behind the ransomware attacks, usually demand payment in virtual currencies like Bitcoin.
8) Phishing Emails
Phishing emails are usually used to steal personal information from the user, while spam email is usually used to flood the Internet with many copies of the same message, which will bring the computer user to this message Attempts are made to compel those who otherwise choose not to get it.
Advantage of Cybersecurity
Better Information Security and Business Continuity Management
Better stakeholder trust in your information security arrangement.
Better company credentials with correct security control
Fast recovery time in case of violation
