Packet sniffing:

For IPv4:

For SYN flag set:
windump -i 1 "tcp[13] & 2 == 2"
tcpdump -i eth0 "tcp[13] & 2 == 2"

For ACK flag set:
windump -i 1 "tcp[13] & 2 != 0"
tcpdump -i eth0 "tcp[13] & 2 != 0"

For FIN flag set:
windump -i 1 "tcp[13] & 1 == 1"
tcpdump -i eth0 "tcp[13] & 1 == 1"

For IPv6:

For SYN Flag set:
windump -i 1 "ip6[6]=6 and ip6[40] & 2 == 2"
tcpdump -i eth0 "ip6[6]=6 and ip6[40] & 2 == 2"

For ACK Flag set: 
windump -i 1 "ip6[6]=6 and ip6[40] & 2 != 0"
tcpdump -i eth0 "ip6[6]=6 and ip6[40] & 2 != 0"

For FIN flag set:
windump -i 1 "ip6[6]=6 and ip6[40] & 1 == 1"
tcpdump -i eth0 "ip6[6]=6 and ip6[40] & 1 == 1"

Hvis man skal få dette til å kjøre sammen med Wireshark under windows, så må man først intallere Windump med tilhørende revisjon av pcap.

Masteroppgave i Cyber Security for OT

Denne masteroppgaven vinkler problemstillingen rundt Cyber Security i et ganske interessant tverrfaglig perspektiv.

Tittelen er:  Ikke-tekniske cybersikkerhetsbarrierer for OT-systemer i petroleumsindustrien. (Men den har nok også relevans utenfor petroleumsindustrien.)

Her er også en annen masteroppgave innenfor beslektet tema:

“Cybersecurity Incident Management Process in Industrial ICT Systems”

https://ntnuopen.ntnu.no/ntnu-xmlui/handle/11250/2781139

Her har vi en masteroppgave som er rettet mot innkjøp i forhold til overføringssystemene for elektrisk kraft. Inneholder kanskje litt generell informasjon som kan være interessant.
