I have developed a multithreaded server/client python application, my next goal is to encrypt the traffic between both parties but I can’t tell where should I invest all my research energy in
Using SSL/TLS has a warning that is really not … Continue reading How to properly secure a tcp server/client application
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?
