Chapter-15, LEC-5 | External Network Attacks Outro | #cybersport #cybersecurity

External network attacks refer to a type of cyber attack that targets an organization's network infrastructure or systems from outside the organization's network perimeter. These attacks are typically initiated by malicious actors who are not authorized to access the organization's network or systems and can cause significant damage to an organization's operations, reputation, and financial stability.

External network attacks can take many forms, including:

Malware attacks - In this type of attack, an attacker sends a malicious software program or code to the victim's system, which can then execute unauthorized actions, such as stealing sensitive data or encrypting the victim's files for ransom.

Denial-of-service attacks - These attacks overload the victim's network or systems with traffic, making them inaccessible to legitimate users. This can disrupt the organization's operations, cause financial losses, and damage its reputation.

Phishing attacks - In a phishing attack, an attacker sends an email or message to the victim, pretending to be a trustworthy source, and lures them into providing sensitive information, such as login credentials, credit card information, or personal data.

Man-in-the-middle attacks - In this type of attack, the attacker intercepts communication between two parties and can steal sensitive information or modify the communication to their advantage.

SQL injection attacks - These attacks exploit vulnerabilities in web applications and databases to inject malicious code into them, enabling the attacker to execute unauthorized actions, such as stealing or manipulating data.

To protect against external network attacks, organizations should implement multiple layers of security, including firewalls, intrusion detection and prevention systems, endpoint protection, and regular security audits and vulnerability assessments. They should also provide employee training on security best practices, such as identifying phishing attacks, using strong passwords, and reporting suspicious activity. It is also essential to keep all software and systems up-to-date with the latest security patches and to regularly back up critical data.
