What is the definition of cyber security?
Communication over the Internet occurs in cyberspace, which is described as an electronic medium for computer networks. This vast network makes up hundreds of thousands of networked computers, servers that carry large amounts of data, routers, modems, and switches. These are connected by tens of thousands of strong fiber-optic cables that run on land and under water, known as submarine cables. As a result, maintaining these networks is everyone's responsibility, both individually and collectively.
Keeping this network secure for individuals, businesses, and governments is now a huge task that requires significant investment in both manpower and infrastructure.
Cyber Security Concepts:
Individuals, small businesses, large organizations, and government agencies are increasingly focusing on securing their systems against all kinds of cyber threats as a result of the increasing number of cyber threats. Cybersecurity, in layman's terms, is the process of defending autonomous computers, a network of interconnected computers, individuals, organizations, government data and highly sensitive national security against malicious cyber attacks.
Cyber security principles and concepts for beginners include knowing how to protect yourself from email scams, malware, viruses, wi-fi security, financial scams, phishing, and safe use of internet resources like social media, among other things. Smartphones are becoming an increasingly important part of our daily lives and require some basic protection. To protect themselves, beginners should understand some basic ideas in cybersecurity and subscribe to antivirus software for personal computers and small business networks.
Automatic or manual two-step or three-step company data backups should be available on premises in case of data loss due to computer failure or hacking.
Cyber security courses:
Attending a basic course can help beginners understand the basics of cyber security in simple words such as securing Wi-Fi/router/modem connections, antivirus software, safe internet browsing, risks of clicking on unknown links, spotting phishing sites, common scams, and scams In SIM swapping, secure use of credit cards and digital payment apps, and more are covered in the basics. These are some of the cybersecurity basics for beginners that must be grasped before entering the cyberspace. However, before delving into this great topic, a newbie should be well versed with the basics of cyber security.
Beginners can prepare for the course by reading some materials such as
1- “Cyber Threat, Know the threat to overcome the threat, by Bob Gurley.
2- “NIST’s Cyber Security Framework.”
3- “The Five Most Common Cyber Attacks” is a list of the most common cyber attacks. from CSO.
What are the types of electronic attacks?
In recent years, there have been a large number of new types of cyber attacks. Many of them are involved in:
1- Denial-of-service attacks by sending massive spam emails or messages aimed at disrupting organizations' servers and websites.
2- Bot attacks through a network of real and fake computer systems spread across multiple continents to hide their origin. They can be used to spread social media messages and emails to target an individual or organization, refuse service, or steal confidential data.
The main areas of cybersecurity:
The CIA's triad, or core areas of cybersecurity, are confidentiality, information, and availability.
It's all about information. It all depends on the confidentiality of information about the organization. Each person only needs a certain type and level of information, and the amount of information available rises as one advances up the corporate ladder. With a password and other security methods, each employee is properly trained to secure and maintain the confidentiality of all information available to him. There is a dedicated department responsible for this for the entire organization, which is protected by a proper firewall.
This is critical to data integrity, as it ensures accuracy, reliability, and consistency of data. It should not be subject to unauthorized access, corruption, tampering or disclosure. Should this occur, there should be a well-defined procedure for threat detection and isolation, as well as data recovery. Access to information is enabled through comprehensive risk assessments and appropriate hardware and software integration. It is tailored to the type of company, the sensitivity of the information present, the overall risk profile, and all potential weaknesses.
It is the duty of every person to be familiar with some concepts of cyber security. If you want to keep pace with the times and enter the digital world, you must learn how to protect yourself from any attack that may threaten your data and privacy.
