What is Smurf Attack?

 

A smurf attack is a form of a distributed denial-of-service attack that renders computer networks inoperable

The Smurf program accomplishes this by exploiting vulnerabilities of the Internet Protocol (IP) and Internet Control Message Protocols (ICMP).

Huge numbers of ICMP requests are sent to the victim's IP address.

The source and destination IP address is spoofed. The hosts on the victim's network respond to the ICMP requests.

This creates a significant amount of traffic on the victim’s network, resulting in the consumption of bandwidth and ultimately causing the victim’s server to crash.

Countermeasures

Configure individual hosts and routers to not respond to ICMP requests or broadcasts; or

Configure routers to not forward packets directed to broadcast addresses.

What is Brute Force Attack?

Brute Force Attack

A brute-force attack consists of an attacker trying many passwords or passphrases with the hope of eventually guessing correctly.

The attacker systematically checks all possible passwords and passphrases until the correct one is found.

When password guessing, this method is very fast when used to check all short passwords.

There is a computer program run automatically to get the password.

The most basic brute force attack is a dictionary attack, where the attacker works through a dictionary of possible passwords and tries them all.

Countermeasures

• Account Lockout - You Have Implemented Account Lockout With A Clipping Level Of 4

• Implement Captcha - It is used to differentiate between real users and automated users, such as bots.

What is Man-In-The-Middle Attack?

It is an attack where the attacker secretly relays and possibly alters the communication between two parties who believe they are directly communicating with each other.

Countermeasures

• Digital Signature - A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents.

• Mutual authentication - Mutual authentication, also known as two-way authentication, is a security process in which entities authenticate each other before actual communication occurs.
