In an era where cyber threats are a constant risk rather than a possibility, businesses cannot afford to be complacent about cybersecurity. This is why it is crucial that you understand what pentesting is. Penetration testing, also known as “pen testing,” serves as a vital diagnostic tool to identify and resolve security weaknesses before hackers…

The Internet Assigned Numbers Authority (IANA) assigns every Autonomous System (AS) on the internet a 16-digit Autonomous System Number (ASN). . This identification number is what allows independent systems on the internet to both control the routing information within their own networks and exchange routing information with other ISPs. In order to understand the Autonomous System…
