Friendly Reminder That Notes Do Look Like A Mess 90% Of The Time And It’s Ok!!

Espresso-stained pages, whispered thoughts between hardcover spines, and mornings that begin with poetry and croissants. A soft life of books, cafés, and intentional stillness.

On today's todo list:

Draft and schedule emails

Review existing literature on my PI's current research direction

Review previous NSF GRFP applications

Look into other national fellowships (listed)

Brainstorm about personal statements + project proposals

I've unfortunately fallen off my daily journaling/work routines the last few months, and I'm working on getting myself back into good habits. Today, my main goal is to schedule all my emails to other PhD programs their declining offers of admission. I just finalized everything with my chosen program this week, and the April 15th decision deadline is looming. I feel terrible for dragging my feet on communications, but I want to make sure I send personalized emails to each professor I interviewed with. I know this is part of the process, but I still hate disappointing people.

On the upside, I've already set up my graduate school accounts, put together a preliminary schedule of my classes in the fall, and set up my new email. I'm eager to get back to work

~Sunday, August 4th 2024~

This weekend was exhausting. Manifesting a good start to the week. Otherwise, I did a bit of CSS yesterday and I only have two more chapters left on the course material.

back at barnes and noble

hi internet people :)

the burnout is hitting me hard today. i don't know if it is work or that this material is getting more difficult but doesn't really matter. we're back at barnes and noble today to knock out a few more sections of css and js. i plan on staying until they close bc i will not do anything if i'm at home. please don't scream at me for the drink, b&n is one of the few places i can be without getting overstimulated easily.

forest time: 1 hr 25min as of 3:24 pm | actual productivity time is about 2.5 hr.

An Introduction to Cybersecurity

I created this post for the Studyblr Masterpost Jam, check out the tag for more cool masterposts from folks in the studyblr community!

What is cybersecurity?

Cybersecurity is all about securing technology and processes - making sure that the software, hardware, and networks that run the world do exactly what they need to do and can't be abused by bad actors.

The CIA triad is a concept used to explain the three goals of cybersecurity. The pieces are:

Confidentiality: ensuring that information is kept secret, so it can only be viewed by the people who are allowed to do so. This involves encrypting data, requiring authentication before viewing data, and more.

Integrity: ensuring that information is trustworthy and cannot be tampered with. For example, this involves making sure that no one changes the contents of the file you're trying to download or intercepts your text messages.

Availability: ensuring that the services you need are there when you need them. Blocking every single person from accessing a piece of valuable information would be secure, but completely unusable, so we have to think about availability. This can also mean blocking DDoS attacks or fixing flaws in software that cause crashes or service issues.

What are some specializations within cybersecurity? What do cybersecurity professionals do?

incident response

digital forensics (often combined with incident response in the acronym DFIR)

reverse engineering

cryptography

governance/compliance/risk management

penetration testing/ethical hacking

vulnerability research/bug bounty

threat intelligence

cloud security

industrial/IoT security, often called Operational Technology (OT)

security engineering/writing code for cybersecurity tools (this is what I do!)

and more!

Where do cybersecurity professionals work?

I view the industry in three big chunks: vendors, everyday companies (for lack of a better term), and government. It's more complicated than that, but it helps.

Vendors make and sell security tools or services to other companies. Some examples are Crowdstrike, Cisco, Microsoft, Palo Alto, EY, etc. Vendors can be giant multinational corporations or small startups. Security tools can include software and hardware, while services can include consulting, technical support, or incident response or digital forensics services. Some companies are Managed Security Service Providers (MSSPs), which means that they serve as the security team for many other (often small) businesses.

Everyday companies include everyone from giant companies like Coca-Cola to the mom and pop shop down the street. Every company is a tech company now, and someone has to be in charge of securing things. Some businesses will have their own internal security teams that respond to incidents. Many companies buy tools provided by vendors like the ones above, and someone has to manage them. Small companies with small tech departments might dump all cybersecurity responsibilities on the IT team (or outsource things to a MSSP), or larger ones may have a dedicated security staff.

Government cybersecurity work can involve a lot of things, from securing the local water supply to working for the big three letter agencies. In the U.S. at least, there are also a lot of government contractors, who are their own individual companies but the vast majority of what they do is for the government. MITRE is one example, and the federal research labs and some university-affiliated labs are an extension of this. Government work and military contractor work are where geopolitics and ethics come into play most clearly, so just… be mindful.

What do academics in cybersecurity research?

A wide variety of things! You can get a good idea by browsing the papers from the ACM's Computer and Communications Security Conference. Some of the big research areas that I'm aware of are:

cryptography & post-quantum cryptography

machine learning model security & alignment

formal proofs of a program & programming language security

security & privacy

security of network protocols

vulnerability research & developing new attack vectors

Cybersecurity seems niche at first, but it actually covers a huge range of topics all across technology and policy. It's vital to running the world today, and I'm obviously biased but I think it's a fascinating topic to learn about. I'll be posting a new cybersecurity masterpost each day this week as a part of the #StudyblrMasterpostJam, so keep an eye out for tomorrow's post! In the meantime, check out the tag and see what other folks are posting about :D
