It will start requesting blocks from all of its connected peers. It requests for spreading the load and en‐ suring that it doesn’t overwhelm any peer with requests. The node keeps track of how many blocks are ‘in transit’ per peer connection, meaning blocks that it has requested but not received, checking that it does not exceed a limit (MAX_BLOCKS_IN_TRANS‐…

    2) Network traffic shows that hundreds of hosts are constantly sending only SYN packets to a single Web server on campus. a. This type of traffic suggests a SYN flood attack, which according to Techtarget (http://searchsecurity.techtarget.com/definition/SYN-flooding) is when half-open connections are attempted by the user only sending SYN packets. The server will respond with SYN/ACK packets (on open ports), but the client ignores them and re-sends SYN packets. This means the server cannot handle legitimate traffic when needed. Similar to #1 above, IDS and IPS devices can detect all of this traffic and an IPS can drop the packets before they get to the target server after the pattern is recognized as an attack.…
