Cybersecurity is a term that is used to describe the protection of computer networks and systems from unauthorized access, use, disclosure, or destruction. Cybersecurity threats can come from a variety of sources, both known and unknown, including cyberattacks, unintentional user actions, and natural disasters.
Cyber Security risks can be categorized as either physical or electronic. Physical threats include attacks on the network infrastructure itself (for example, break-ins), while electronic threats include unauthorized access to data or computer networks through the use of malware or cyber espionage.
There are many types of cybersecurity threats, but some of the more common ones include:
Malware: Software that is designed to damage or steal data.
Viruses: Software programs that can spread automatically from one computer to another through contact with removable media (like USB drives) or email attachments.
Spammers: Individuals or organizations who send an unsolicited bulk email (email messages that are not sent to specific recipients).
Phishing: The practice of trying to obtain personal information such as login credentials by masquerading as a legitimate entity in an email.
In order to understand how cyberattacks are executed in cyberspace, one must first understand the ways in which computers function. When a user accesses a website, for example, their computer sends a request to the website’s server. This request contains information about the user – such as their browser type and IP address – and the website’s response will be sent back to the user’s computer.
There are many ways that hackers can attack a computer system, but the most common way is by trying to guess your passwords. Attackers also use other methods, such as viruses and trojans, to infiltrate systems. Once they are inside, they can steal data, plant malware, or spy on your activity.
One of the most important things you can do to protect yourself from cyber attacks is to change your passwords often and make sure that you never give out your personal information, such as your date of birth or bank account number, to anyone.
