PC Security Vulnerabilities

A system or any other device can be vulnerable when they are prone to kind of malicious attack.

The three main ingredients of Vulnerability

• A system flaw

• the access of hacker to the flaw

• the hacker exploiting the flaw

System vulnerabilities often open the door for a hacker to attack the system. It is also called as the attack surface. There are many ways that the system can be attacked. To know how to secure your computer from vulnerable attacks, you should first have knowledge about the various modes of attacks and the threats responsible for it.

• Backdoors

• Denial-of-service attack

• Direct-access attacks

• Eavesdropping

• Spoofing

• Tampering

• Data Breaches

Backdoors - A backdoor is an algorithm that escapes authentication and validation factor of security and helps the cybercriminal to remotely access the computer and remains undetected.

Denial-of-service attack (DoS) - They are developed and generated by cyber criminals on the targeted machine to render it unusable. This is also called as distributed Denial of Service (DDoS) attack. They create an attempt to ensure that the network resources are unavailable for the users to access it.

Direct-access attacks - Cyber criminals can perform an unauthorized remote access on its victim's computer remotely. By doing so it can compromise the system's security, Keyloggers, computer worms are some kind of malware that can process an unauthorized remote access, thereby the criminal downloads a huge amount of sensitive data from the target victim.
