Cyber security is a method of protecting computers, servers, mobile devices, electronic systems, networks and data from malicious attacks.
Types of Cyber Security Threats
Malware
Malware is malicious software, such as spyware, ransomware, viruses, and worms. When it activates when a user clicks on a malicious link or attachment, which may lead to the installation of malicious software.
- Restrict access to major network components (ransomware)
- Install more malicious software
- Get confidential information by transferring data from a hard drive (spyware)
- Disable individual components and disable the system
Denial of Service
Service denial (DoS) is a type of cyber attack that attacks a computer or network so that it does not respond to requests. Distributed DoS (DDoS) does the same thing, but the attacker originates from the computer network. Cyber attackers often use flood attacks to disrupt the “handshake” process and manage DoS.
There are many other strategies that can be used, and some cyber attackers use network time to launch other attacks.
Phishing
Phishing attacks use fake communications such as e-mails to manipulate notifications such as recipient numbers and credit cards. “It aims to steal sensitive data such as credit cards and login information or install malware on the victim’s computer,” Cisco explained.
Password Attacks
With the right password, cyber attackers can have a wealth of information. Social engineering is a type of password attack that Data Insider “relies heavily on human communication technologies used by cyber attackers and generally deceive people into violating standard security practices.” Other types of password attacks include accessing or guessing password databases.
Man-in-the-Middle Attack
Man-in-the-middle (MITM) attacks occur when criminals obstruct traffic between two individuals. For example, criminals can insert themselves between public WiFi and a person’s device. Without a secure Wi-Fi connection, cybercriminals can sometimes see all of a victim’s information without being caught.
SQL injection
Structured Query Language (SQL) injection is a type of cyber attack that involves inserting malicious code into a server that uses SQL. When infected, the server issues information. Submitting malicious code is as easy as entering a malicious website search box.
Dridex Malware
Dridex is a financial Trojan with a wide range of capabilities. Affects victims since 2014, affecting computers via phishing emails or existing malware. This has resulted in financial loss of crores of rupees, including the ability to steal passwords, banking details and personal data used for fraudulent transactions.
Emotet malware
Emotet is an advanced Trojan that can steal data and load other malware. This evolves with advanced passwords: Reminds us of the importance of creating secure passwords to protect ourselves from cyber threats.

Why is cybersecurity important?
Cyber security is important because it covers everything related to protecting our data from cyber-attackers who use it to steal and damage information. This could be sensitive data, government and industry information, personal information, personally identifiable information (PII), intellectual property and protected health information (PHI).
Having extensive cyber security programs and procedures to protect this data is crucial and in everyone’s interest. Everyone in the community depends on complex infrastructures such as hospitals, other healthcare facilities, financial service programs and power plants. These are essential to sustain our society.
End-user protection
End-user security or endpoint security is an important component of cyber security. After all, usually, a person (end-user) accidentally loads malware or some other type of cyber threat onto their desktop, laptop or mobile.
How do cyber security measures protect end-users and systems? First, cybersecurity relies on cryptographic protocols to encrypt emails, files, and other sensitive data. This not only protects the information in transit but also protects it from damage or theft.
Additionally, end-user security software scans the computer for malicious code, blocks this code and removes it from the machine. Security programs are designed to detect and remove malicious code hidden in the primary boot record and to encrypt or delete data from a computer hard drive.
Security programs will continue to develop new defences as cyber security experts identify new threats and new ways to deal with them. To get the most out of end-user security software, employees must be educated on how to use it. Most importantly, running it and updating it regularly will ensure users are protected from the latest cyber threats.
Conclusion:
To protect your business and computers, you must update the Operating System, install the best antivirus, use high-security passwords, don’t click any suspicious email link from an unknown sender.
