Cybersecurity provides physical security measures such as system locks, intrusion detection systems, alarms, surveillance systems, and data-destruction systems help organizations safeguard their valuable assets and maintain the security of the overall system.

Rules and Security:

Cybersecurity plays a crucial role in establishing guidelines and regulations for users, attackers, and network participants to stick to while using the Internet. It empowers authorities to address security concerns and optimize the network accordingly.

Compliance and Investigations:

Cybersecurity plays vital role in examination of suspicious situations and ensuring the safety of digital environments.

Threats of Cyber Security:

When it comes to cyber security, various types of threats can put individuals, organizations and even nations at risk. These threats are:

Malware:

Malware is a type of malicious software that poses a significant threat to cybersecurity. It refers to various forms of harmful programs, such as viruses, worms, and Trojans, that can infect computer systems and cause damage. Malware can be spread through infected websites, email attachments or even removable storage devices. Some malware is designed to remain hidden and operate silently, making it difficult to detect.

Phishing:

Phishing is a deceptive technique used by cybercriminals to trick individuals into revealing sensitive information. It typically involves sending fraudulent emails or messages that appear to be from trustworthy sources, such as banks or popular websites. These phishing messages often create a sense of urgency or use scare tactics to prompt recipients to click on malicious links or provide their confidential information.

Ransomware:

Ransomware is malicious software that can cause significant damage to computer systems and data. It works by encrypting files on a victim’s device, making them inaccessible until a ransom is paid to the attacker. Ransomware can be distributed through various means, such as malicious email attachments, infected websites, or compromised software. It can target individuals, businesses, or even entire networks, causing extensive data loss and financial harm.

Data Breach:

A data breach is a cybersecurity incident where unauthorized individuals gain access to confidential information. It can occur due to various reasons, such as hacking, malware attacks, or human error. During a data breach, personal or financial data can be stolen.
