Computer security, as I see it, has become a bit like the belt in car. 🚘
Not because it's "fashion" (in fact: no one wakes up happy thinking about patches), but because at some point you stop considering it an accessory and start treating it like a part of the journey.
And the journey today is digital: emails, documents, payments, internal chats, CRM, suppliers, cloud... everything goes through there. 📬
So yes, we can also pretend that security is an "IT" thing, but then it only takes a moment to find out that it concerns anyone who works, decides, signs or simply opens an attachment.
The following is not a cybersecurity manual. It's more like a personal reasoning, a little argumentative, about what it really means "Make sure" nowadays.
Spoiler: It's not just buying a firewall Bigger. 🏋🏻♂️
Computer security is not paranoia... it's more hygiene
For years we've treated security as we treat emergency plans: useful, yes... but until nothing happensThey stay in the drawer.
The problem is that computing is no longer a department. It is the air that breathes in the company. And when the air is compromised, not "IT stops": job stops.
That’s why I’m less convinced of the idea of security as a "project": let’s do the security assessmentLet's get two things done, close the ticket and go.
Computer security works best when it is a habit. When it enters small gestures:
- "Does this email make sense? "
- "Do I really need this access? "
- "where does this file end? "
- "If I lose my account tomorrow, what happens? "
They're boring questions, yes. But it's the questions that keep everything going. 🧑🔧
The real enemy is not the hacker: it is normal
One idea that often returns in cybersecurity talks is: "they attack us." As if the threat was a rare, spectacular, almost film event.
Reality is more trivial (and therefore more dangerous): most problems arise from normality. Hurry up. The passwords you used. From data permissions "temporarily" and never revoked. From shares made "for convenience only". From the backup that "there is so much" but you have never tried to restore.
It is here that security becomes a cultural and technological issue: risk is not the ‘sophisticated attack; risk It's the baby. error repeated 1,000 times in an organization. ⚠️
And if that sounds like a moralistic speech, I'm gonna put it another way: You don't have to be incapable to make a mistake. Stop being human.
Perfect security does not exist (and chasing it is a mistake)
Here I take a clear position, chase the "total security" is a trap (does it really exist? !).
Because it leads you to two typical side effects:
- Block All, slow down the job and eventually people look for shortcuts.
- You're delusional you're okay., because you bought expensive tools and you have a dashboard full of charts. 💸
Good security, however, is the one that holds in real life. The one that does not depend on the IT hero who "knows everything"🦸🏻♂️But from simple and repeatable processes. What if someone is wrong (because it will happen), the damage remains contained.
In other words, the Safety is not eliminating the risk. Is manage it.
"But we are little": the most dangerous phrase in the world
If there is one conviction I would like to retire is this: "We're too young to be interested in someone”. 😎
That's not how it works!
Many attacks today are not "custom": I am automated, Industrial. They scan, try, enter where they find a door ajar.💣And often a small company is a perfect door ajar because:
- ha less controls,
- ha less time,
- ha Less training,
- and often has a mix of tools put together over the years.
And even when the goal is not your company, it can be your supplier, your customer, an email of "fake invoice" at the wrong time. The point is thatecosystem is interconnectedYou're a target just because you exist inside a chain. 🌐
The three things that I think really change security
I'm not giving you the endless list of 100 tips to be sure. I tell you what, in practice, moves the balance needle.
1) Identity and access: who can do what (and why)
If I had to choose one concept: Controlling access is more important than buying new defenses.
- MFA everywhere is possible (yes, even if it "noises").
- Name accounts (only shared users). 🕵️♂️
- Minimum privileges: access only to what is needed.
- Periodic review: people change roles, permits remain. 👮♂️
Safety often does not collapse for a bug, but for a access too wide Given too long ago.
2) Serious backup: not "we have it", but "functional"
Backup is one of those themes that everyone takes for granted until you need it. 💾
A "serious" backup is not just a copy. It's:
- adequate frequency,
- versioning (to go back),
- isolation (not to be encrypted together with data),
- Recovery tests, sometimes, really.
It is not glamorous, but it is one of the few things that transforms a disaster in a bad afternoon And trust me, you only realize it when it happens to you.
3) Awareness: the formation that does not bore
Effective training is not to make a slide a year with "Beware of phishing". 📥
Is creating amental habit, doubt in a healthy way, stop for a moment, ask confirmation.
And above all, avoid the culture of guilt. If one is afraid to admit "I clicked", you find out late. If you know what to report now 🚨 is appreciated, reduce damage.
The right question isn't "How sure are we?" but "How ready are we? "
Security, in the end, is also a matter of resilience.
I would trust much more than a company that says:
"We're not invincible, but we know what to do if something happens." 👨💻
... rather than a company that says:
"Don't worry, we're super protected" 🙂↔️
Being ready means having:
- Clear responsibilities (who decides what, when),
- contacts and procedures (interior/suppliers),
- escalation criteria,
- a minimum of operational continuity plan,
- and the ability to communicate well (in and out).
Because when an accident happens, the problem is not only technical: it is operational, reputational, legal, human.
Making sure is choosing not to postpone?
If I have to end with a Personal Thought I'd say computer security is more of an act of maturity.
Not because you need to be afraid. On the contrary, because you stop relying on luck.🍀 Stop hoping that "you don't happen to us." And start building an organization it all works even when something goes wrong.
And the good thing (yes, there is one good thing) is that You don't have to revolutionize everything. Tomorrow morning. Often just start with a simple question, repeated consistently:
"This choice, this procedure, this access... more robust or more fragile?”
