Chapter-15, LEC-1 | External Network Attacks Introduction | #ethicalhacking #cybersecurity

External network attacks are a type of cyberattack in which an attacker attempts to exploit vulnerabilities in a computer network from outside the network's perimeter. These attacks can be launched from anywhere in the world and are becoming increasingly common as more organizations rely on computer networks for their daily operations.

External network attacks can take many forms, such as:

Phishing: attackers send emails, messages or texts with links to fake websites to trick users into giving away sensitive information, such as login credentials or credit card numbers.

Malware: attackers can use various types of malicious software, such as viruses, worms, or Trojan horses, to infiltrate networks and steal sensitive data.

Denial of Service (DoS): attackers can flood a network with traffic to cause it to crash or become unavailable to legitimate users.

Man-in-the-middle (MITM): attackers can intercept communications between two parties to steal or modify sensitive information.

Password attacks: attackers can use various methods to guess or steal passwords, such as brute-force attacks or phishing.

The impact of external network attacks can be devastating, including theft of sensitive data, financial loss, and damage to an organization's reputation. Therefore, it is essential for organizations to have robust security measures in place to protect their networks against external threats. This can include firewalls, intrusion detection and prevention systems, regular software updates, and employee training programs to raise awareness about cyber threats.
