DNS Cache Poisoning Attacks: Understanding the Security Threat

🔒DNS cache poisoning is a technique used by attackers to manipulate DNS responses and redirect users to malicious IP addresses.

🌐DNS is a system that links domain names to their corresponding IP addresses, allowing users to access websites through human-readable URLs.

🔑DNS cache poisoning attacks can lead to various security risks, such as phishing, malware distribution, and data theft.

⏱️The time-to-live (TTL) value in DNS cache determines how long a response is stored, affecting the duration of cache poisoning attacks.

🛡️Implementing DNS Security Extensions (DNSSEC) can mitigate the risks of DNS cache poisoning attacks by providing authentication and integrity checks.

What is DNS cache poisoning?

—DNS cache poisoning is an attack where an attacker manipulates the DNS cache of a name server to redirect users to malicious IP addresses.

What are the risks of DNS cache poisoning attacks?

—DNS cache poisoning attacks can lead to various risks, such as phishing, malware distribution, and data theft.

How can DNS cache poisoning be prevented?

—Implementing DNS Security Extensions (DNSSEC) can help prevent DNS cache poisoning attacks by providing authentication and integrity checks.

What is the role of Time-to-Live (TTL) in DNS cache poisoning?

—The TTL value in DNS cache determines how long a DNS response is stored, affecting the duration of cache poisoning attacks.

Are DNS cache poisoning attacks common?

—While DNS cache poisoning attacks are less common nowadays due to security measures, they still pose a significant threat.
