Is the call encrypted with something like HTTPS to prevent a corrupt government (or ISP) from messing with the DNS routing, sniffing, snooping etc? Can my ISP or government listen to my Skype calls?
I’m calling a bank’s 800 number from Sky… Continue reading Can my ISP or government listen to my Skype calls?
I have written a simple C program (~30 lines) that opens an internet socket and sends data to the client on every connection. The program never read()s from the socket; it just parses the /proc filesystem and write()s the output to the soc… Continue reading Is an open TCP port that doesn’t take input secure?
In my search for a comprehensive list of implemented RFC’s as pertaining to TCP/UDP traffic, I’ve come across RFC 7414 – but it only provides links and only for TCP. Is there any project that either meta-analyzed these, or that has been ma… Continue reading Is there a way to filter RFCs for what would constitute minimum allowed TCP/UDP traffic for functioning of web applications?

Statement (In Interview):
ARP spoofing attacks are more effective for UDP packets rather than
TCP packets since TCP establishes reliable communication channels.
I have opposed the statement saying that once ARP spoofing is done, then we … Continue reading ARP spoofing on TCP and UDP
I’m trying to set up port knocking using iptables on a Debian server hosted by VirtualBox on my Ubuntu machine. For some reason, when I knock on a port on the server from the host machine, this knock is automatically repeated several times… Continue reading Why does my simple TCP connect cause a cascade of repeated connection attempts on my vitual server?

Since TeamViewer is using a Master Sever to help connect two clients behind NATs it is very likely that UDP hole punching is used to establish a connection.
But in the TeamViewer settings, you can set the used Transport Protocol to TCP.
Is… Continue reading Is TeamViewer using TCP Hole Punching? [closed]
I’d like to know if this communication technique is secure enough against attacks, both on the connection itself and the password-storing procedures.
Both the client and the server have access to 2 pre-shared static keys:
Enc Key A (32-by… Continue reading Is this TCP socket encryption and password storage implementations secure enough?
If a script tag https://domain.com/script.js is loaded to a website, and then in this script there are additional calls to the same domain, such as an AJAX (xhr) request to https://domain.com/another-resource, will the browser do the SSL n… Continue reading Does the browser reuse the SSL negotiation process (and/or the tcp connection) for additional resources? [migrated]
I understand the TCP meltdown problem is associated with overcompensation from errors and incorrect sequencing when arriving the the receiver end. OpenVpn connections are recommended to use the UDP protocol.
Does this mean that the connect… Continue reading Can UDP traffic be transmitted over TCP ports on OpenVpn to avoid the TCP meltdown [closed]
