SYN cookies: my personal preference is SYN cookies where the firewall acts as a handshake proxy: incoming syn packets are not immediately put into the session table but rather a cookie is generated and sent back to the source. If the sender fails to respond with an ap...
DDoS attacks can lead to various consequences such as lost sales, damage to consumer confidence, forced compensation pay-outs by companies, and long-term harm to a company’s reputation, among other things. Thus, it is essential to have a plan in place to prevent, detect, and respond to D...
It is computationally cheap to execute an HTTP request on the client side, but it can be expensive for the target server to respond because the server typically must load multiple files and run database queries to create a web page. HTTP Flood is one type of application-layer attack, which...
One type – aDomain Name System (DNS)amplification attack – uses “botnets” to spoof the target IP address and make requests to an open DNS server. This causes the server to respond to the target IP and overwhelm the resources. Protocol layer attacks Protocol or infrastructure layer attacks ...

Respond in real time with rule-based event correlation Botnets work by overwhelming legitimate online services to the extent that the online service can't handle the volume of activity and is effectively offline for the duration of the attack. A botnet can lie dormant until it receives instruction...
What is DoS or Denial of Service Attack In a DoS attack, an attacker with malicious intent prevents users from accessing a service. He does so by either targeting your computer and its network connection or the computers and network of the website that you are trying to use. He can thus...
DDoS attack traffic A DDoS attack isn’t the same thing as hacking, although the two can be linked; the perpetrators aren’t attempting to access your website’s files or admin, but instead, they cause it to crash or become vulnerable due to the volume of requests. In some cases, this...
What is a DoS Attack To understandwhat is a DDoS attack, it’s necessary, first of all, to analyze theDoSattacks. Acronym for Denial-of-Service, a DoS attack is a deliberate action that aims to saturate the resources of a computer system that provides a service to the client connected ...
