Some NPM vendors started pairing DNS lookup records with flow data in order to separate business applications from non-business applications hosted on the same IP address. The problem is that many companies have several DNS servers spread out in far-reaching locations, and not all DNS vendors allow access to the logs.

While redundancy is a significant contributor to network resilience, other mechanisms, protocols, and methods can also contribute to overall network resilience. Many network protocols have been designed to handle different aspects of this process. Let’s highlight some of the primary protocols.

There exist several protocols, from different network layers that can be used for OS fingerprinting. Figure 1 displays these protocols, based on the Open Systems Interconnection (OSI) model. Over this protocol, a unique physical identifier, called the MAC address, is allocated to the network interface card (NIC) of each network device.

Our first thought was that perhaps the legacy router is faster at forwarding requests to the dyno because its underlying TCP client manages connections in a way that plays nicer with the Puma server. dyno root@router.1019708

In simple terms, Border Gateway Protocol (BGP) is the protocol that routes traffic on the Internet. During last week’s attack, the attacker was redirecting traffic that belonged to Amazon’s Route 53 DNS servers. Here we have the DNS clients sending their DNS queries to the hijacked blocks advertised by AS10297.

In addition to basic data like source and destination IP address, port, protocol, etc., we collect network performance metrics like TCP connection setup latency, retransmitted and out-of-order packet counts, and window size.

In the early days of the internet the internet was protocol driven, decentralized, and often distributed—FTP (1971), Telnet (<1973), FINGER (1971/1977), TCP/IP (1974), UUCP (late 1970s) NNTP (1986), DNS (1983), SMTP (1982), IRC(1988), HTTP(1990), Tor (mid-1990s), Napster(1999), and XMPP(1999).

The victim can update DNS to point at a different IP address in an attempt to get their application back up. However, if the attack is targeting the DNS hostname and not the IP address, the attack will just switch over to the new IP address. IP Protocol. The mitigation actually “completes the attack.” Destination Prefix.

According to Akamai’s Q1 2015 State of the Internet report , over 50% of volumetric attacks are IP flood attacks involving a high volume of spoofed packets such as TCP SYN, UDP, or UDP fragments. So next we’ll look at the protocol and destination port # of the traffic. DDoS detection and analysis cases.

It isn’t so much that packet loss is a huge problem — TCP and QUIC were engineered in anticipation that lost packets would be inevitable. Latency : Missing packets in connection-oriented protocols such as TCP and QUIC result in lost packets getting resent. UDP vs. TCP. Packet Loss Causes Problems with Cloud Applications.
