Before going into the definition of Cybersecurity let’s cover some basics. Online communications take place in cyberspace, which is described as an electronic medium of computer networks. Hundreds of thousands of networked computers, servers carrying large amounts of data, routers, modems, and switches make up this vast network that makes the transfer of critical electronic data possible.
Cybersecurity is defined as the use of various applications, technologies, manpower, and measures to protect electronic data.
These are linked by tens of thousands of powerful optical fibre cables that run both on land and under the water, known as submarine cables. As a result, maintaining these networks is everyone’s responsibility, both individually and collectively.
Keeping this network safe for individuals, companies, and governments have now become a massive undertaking that necessitates a significant investment in both manpower and infrastructure. The act of protecting all of these from cyberthreats and cyberattacks using different applications, tools and the measures taken to protect the electronic data is the definition of cybersecurity
Individuals, small enterprises, large organizations, and government agencies are increasingly focusing on securing their systems against all types of cyber threats as a result of the rising number of cyber threats.
In layman’s terms, cybersecurity is the process of protecting individual computers, networks of interconnected computers, individuals, organisations, and extremely sensitive government and national security data against destructive cyber attacks.
Cybersecurity, in layman’s terms, is the act of defending standalone computers, a network of interconnected computers, individuals, organizations, and highly sensitive government and national security data against harmful cyber attacks. Adopting several Cybersecurity principles to meet the needs of the users is part of this approach.
Cybersecurity principles and concepts for a novice include knowing how to protect yourself against email scams, malware, viruses, wi-fi security, financial scams, phishing scams, 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 must comprehend some basic ideas in cybersecurity and subscribe to anti-virus software for personal computers and small business networks.
Regular 2 or 3 step auto or manual backups of corporate data must be provided for in business premises in case of data loss due to a computer crash or hacking.
Key Areas Of Cybersecurity
The CIA trinity or core areas of cybersecurity are
Confidentiality, Information, and Availability are the CIA trinity or key areas of cybersecurity.
Everything revolves around information. All of this is contingent on the secrecy of information about an organization. Each person needs only a specific type and level of information, and the amount of information available rises as one progresses up the corporate ladder.
Through a password and other security methods, each employee is properly trained to secure and maintain the confidentiality of all information available to him. A dedicated department is in charge of the organization’s entire cybersecurity, which is protected by an adequate firewall.
This is critical for data integrity since it ensures the accuracy, dependability, and consistency of data. It should not be vulnerable to unauthorized access, corruption, manipulation, or disclosure.
If this occurs, there should be a well-defined procedure in place to detect and isolate the threat, as well as recover the data. Information accessibility is enabled by thorough risk assessments and the integration of appropriate hardware and software.
It is tailored to the type of company, the sensitivity of the information housed, the overall risk profile, and all potential weaknesses.
