Again my weekly security sprints arrives in late, but I hope not too late as this time, I’m experimenting with dangerous new horizons, such as Perl and Forensics. I approached to Perl with respect and, yes why not saying it, fear. First of all everyone, except my cloud computing teacher, warned me about the complexity of this language. Anyway I tried to made it the easy way, and searched for help in an already prepared script for security I found on GitHub. The script is quite clear and organized which helped me to both learn perl and...
Recently something amazing was added in my university’s library: you can ask not only for for books but also for electronic programming bundles such as Raspberry or Arduino kits. I decided to take a Raspberry Pi kit in order to make an experiment: a network capture probe.
A network capture probe is a tool for network system monitoring that allows you to capture traffic in real-time. I learned about this technique not long ago when I met a guy who was wearing one of those in his bag everywhere using his Raspberry...
I found a nice topic to write about: CA pairs creation with openssl in Linux. A digital certificate tells an application (a browser, for example) that a public key is owned by the one who calls it. This allows relying parties to rely upon signatures made to this public key. OpenSSL is a free and open-source cryptographic library that provides several command-line tools for handling digital certificates. So, for now we are working on
root so first of all I suggest to
sudo -i and then do the rest.
In this case we are working on a directory...
Basically, distributed ledger is the concept of sharing data evolution control in a common network. One of the most famous examples of this are BITCOINS, which works over a blockchain, a data base distributed between several participants (nodes) inside a ledger, which contains the updated status of each transaction between the nodes. These nodes are connected using a specific protocol.
The key of this system’s movement lays on Token, elements that contains information and are encrypted. This token could act as a currency, vote, message, or anything that can be fixed in Distributed Ledger system. Several startups saw in this...
