You can also look at the companies that have done well in this area and learn from them. For example, a recent article describes how Telekom Malaysia adopts the internal and external Method for migrating to IPv6, and IPv6 supporters need to be prepared to persuade the management to understand the advantages of IPv6, these advantages are not very obvious and easy to see. In addition to pointing out IPv6 Security Issues, Neetha Edwin also talked
Practice of setting a route table to restrict Website accessThe website that received this experiment: for short, "website", PING the website domain name and obtain the IP address. The IP address ends with. 69 www.2cto.com. Then, we can find out how many hops the route goes through under tracert.Www.2cto.com uses SolarWinds. Engineers to scan the IP address segment of the website. We know that there is a Cisco router in the website CIDR block, which t
user data packet protocol on port 1900. Within 24 hours, 539 matching modes appear. This indicates that the attacker exists.Because forwarding traffic data is only a feature of some routers and switches, you need to find a way to capture and view the data. You can use VPC analysis tools from companies such as SolarWinds, NetScout, or lanw.cn, or use the aforementioned log management tools. I chose 21 Ct's LYNXeon tool because it not only analyzes the
