Experiments in AI-assisted publishing (coding and cybersecurity)

I am using NotebookLM more and more, for various tasks related to teaching and research. I have to read quite a lot of technical and scientific reports as part of my job and I find it really hard to keep track of all the important insights and news that I discover every day. One extremely useful application of NotebookLM is summarising such sources: sources that I have actually read and that I actually find important . I have decided to start sharing some of these reports publicly. I think some of these topics are very important and maybe there is someone interested in looking at an automatically-generated summary ( that I have read and checked ) of sources that I have carefully selected .

AI and Cybersecurity

I wish I had the time to write down my thoughts on all the important news and misleading information related to 'AI and cybersecurity'. I don't expect people to be interested in reading my thoughts on this topic, but I feel the need to write something down anyway. Even though I don't have enough time to write a clear and concise summary, recent news has urged me to write something, if only to get my thoughts down on paper. While reading the following, please bear in mind that it is an incomplete summary of my views. Why should I study Cybersecurity? I can defend my systems by asking the AI. AI is going to harden my defenses and solve all my defensive problems. Microsoft is one of the companies trying to convince us that AI, including in the field of cybersecurity, will solve all our problems. They are heavily pushing us to use Copilot — one of many incarnations of the LLM models that support ChatGPT — in almost all Microsoft tools. One of the most heavily promoted appl...

Cose che racconto nei corsi (e che poi si verificano) - UPDATED

Reti di Calcolatori e Principi di Cybersecurity , intorno alla fine di settembre: " Il DNS è una infrastruttura critica per il funzionamento della società. Pensiamo a cosa accadrebbe se si bloccasse completamente la risoluzione di alcuni nomi. " Il 20 ottobre 2025 molti servizi Internet usati da molti milioni di utenti in tutto il mondo si sono bloccati o sono diventati lentissimi. Tra questi Apple Music, Airbnb, Spotify, Reddit, Perplexity AI, Duolingo, Goodreads, Fortnite, Apple TV, Mc Donald's App, Signal e molti altri (compresi alcuni servizi della pubblica amministrazione UK). Tutti questi servizi dipendono in tutto o in parte da funzionalità software in Amazon Web Services (AWS), uno dei principali fornitori di servizi cloud al mondo. AWS è composto internamente da molti servizi software. Il motivo scatenante del blocco globale è stato un problema nella risoluzione DNS del nome di un particolare servizio usato internamente in AWS.

One must write correctly. One must explain oneself clearly.

The title of this blog says it all. It is a deep truth of fundamental importance in every profession . I have always tried hard to convince students of this fact. Explaining things clearly and correctly, whether in written or in spoken form, is hard .  It takes a lot of time and experience. Most importantly, some people may have more innate talent. Others may have fewer. However, the first step is to convince oneself of the importance of this fact. Otherwise, the battle is lost before it has begun. I have come to believe that many students have a problem in this respect, as they do not realize how important it is to be clear and correct in our own language. They either believe that technical skills are all that is needed, or that they will magically become perfectly understandable to everyone at some unspecified point in the future. This is definitely not the case. Consequently, they will encounter many unexpected and challenging obstacles in their professional careers. Writing...

AI and Cybersecurity

More than a year ago (January 2024), I gave a presentation at a meeting entitled "Crime and new technological frontiers", held at the University of Trieste and aimed mainly at local police forces. A major focus of the meeting was, needless to say, the cybersecurity implications of so-called artificial intelligence. My opinion was quite strong and somewhat unpopular (as is often the case): We should not be particularly worried. There is no significant evidence of AI usage for phishing/spearphishing.  I think this fact will hold for a long time. The main AI-related risk in cybersec is "getting distracted by its promises": for MANY serious problems we have practical and effective solutions...but we don't apply them! Every year, cybersecurity companies publish a report summarising the main trends they have observed. A few days ago, I read two commentaries on the 2024 data that confirmed my opinion. This is Kevin Beaumont : My main observations: Firstly, no mention o...

Cybersecurity: some of today's news

Every day there is a lot of interesting news related to cybersecurity. Many of these news items are closely related to topics discussed in my Cybersecurity course . Sometimes these news are very closely related to the lectures of a few days ago. Yesterday was a very interesting day in this respect. On Tuesday we discussed how to attribute a specific attack campaign to a specific threat group, what IoCs (Indicators of Compromise) are, their role in attribution, and how they can be used by a defender. Yesterday I found a report that discusses all these issues in a nice and easy to read way, with reference to a specific attack campaign attributed to a Chinese threat group. The report includes a technical description of the software tools used, including "living off the land" tools (another term we discussed), a description of the download and execution steps of the infection chain and, of course, a mapping to the MITRE ATT&CK Enterprise Matrix (the report mentions LSASS dum...

La PhD school più importante della mia vita

Mi è tornata in mente proprio in questi giorni che ho iniziato il corso di Cybersecurity , nel quale parlo più volte dei design principles proposti da Saltzer e Schroeder nel loro capolavoro del 1974 . Se potessi incontrare Mike Schroeder oggi gli esprimerei con grande entusiasmo la mia ammirazione per quel suo capolavoro, nonostante la mia veneranda età e nonostante non abbia più la passione per la tecnologia e la ricerca che avevo da giovane. La cosa curiosa è che Mike Schroeder l'ho incontrato proprio quando ero giovane ed entusiasta: era un docente di quella PhD school...solo che non sapevo nulla di cybersecurity e quindi non ero a conoscenza di quel suo capolavoro, nonostante lo avesse scritto quasi venti anni prima! Mea culpa, mea grandissima culpa. Lisboa 92 - An advanced course on distributed systems Sono stato studente di solo due PhD schools...il titolo di questo blog post è quindi un pò clickbait . Comunque, Lisboa 92 è stata davvero molto importante per me. Non tanto ...
