Which the following is NOT a reason why it is difficult to defend against today's attackers? a. increased speed of attacks b. simplicity of attack tools c. greater sophistication of defense tools d. delays in security updating

The correct answer to the question is OPTION C "greater sophistication of defense tools"

Explanation:

An attacker is the individual or organization whose activities are illegal because they usually aim at ''stealing" people's information or getting access to their accounts without prior knowledge of the victim.

Atimes, website developers make mistakes thereby exposing files on the web server outside of the directory of the website. This files are readable by attackers who capitalize of the mistake who use command injection to carryout an attack, while some attackers use scripts or programs developed by others to attack computer systems and networks.

increased speed of attacks makes it difficult to secure computers from attackers beacause, attackers use modern simple tools  that are fast such that it can quickly scan systems for weaknesses and expose the vulnerability to carryout an attack.
