What does the following option in the /etc/sysctl.conf file do? net.ipv4.icmp_echo_ignore_broadcasts = 1 Ignores Internet Control Message Protocol (ICMP) messages that do not conform to standards Prevents systems from replying to broadcast ping requests Protects from SYN floods Prevents Internet Protocol version 4 (IPv4) forwarding on a system

Which of these countermeasures might be helpful in preventing against a SYN flood attack? a. End systems perform egress screening of IP packets to ensure they are generated from valid sources. b. Routers perform ingress screening of IP packets to make sure that they are coming from valid sources. c. Prevent all further connections after the limit of connection requests is reached. d. Use an intrusion detection system (IDS) to monitor for rates of SYN requests greater than normal, and try to limit these.

An analyst is reviewing the following output as part of an incident: ICMP ECHO REQUEST 192.168.1.10 -> 10.20.30.40 Length=10 ABCDEFGHIJ ICMP ECHO REQUEST 192.168.1.10 -> 10.20.30.40 Length=15 ABCDEFGHIJ ICMP ECHO REQUEST 192.168.1.10 -> 10.20.30.40 Length=20 ABCDEFGHIJ1234567890 Which of the following is MOST likely happening? - The hosts are part of a reflective denial-of-service attack. - Information is leaking from the memory of host 10.20.30.40. - Sensitive data is being exfiltrated by host 192.168.1.10. - Host 192.168.1.10 is performing firewall port knocking.
