Security 360: What I've learned in recent years

Maybe this post isn’t for you…

But I decided to write down what I’ve learned in recent years about information security in the corporate world. It’s just one personal perspective, built on experience, study and lessons from that period.

Spoiler Alert!
It’s all about communication.

Security 360: What I’ve learned in recent years

1. Security goes beyond technology.
   Information security is not an isolated process. It’s only the tip of the iceberg. Good security management rests on knowledge that cuts across every process in an organization.

   For many years I worked directly on the technical side, in analysis and development, and I moved naturally into information security because my foundation was already aligned with it.

   Over time, I realized that many of the failures I was handling were the result of causes in other processes or departments. The need for a view beyond technology became clearer and more obvious.

   On top of that, the market got more demanding: awareness grew, external threats intensified, incidents made headlines in the mainstream press, personal data became more valuable and LGPD (Brazil’s General Data Protection Law) matured.

   My main lesson starts here: information security goes far beyond technology.

2. An organization is only as secure as its weakest link
   The journey continues when we accept that the attack surface extends to every process. Just as water finds the path of least resistance, vulnerabilities are almost always exploited through the weakest link: human error or persuasion.

   A 360 view makes it clear that you have to protect the organization as a whole. There are opportunities (and risks) in every process. Technology helps, but it can’t solve the problem alone.

3. The devil hides where there’s no glamour.
   As technical solutions mature and get harder to break, attackers look for gaps in bureaucratic, legal or contractual processes, precisely the ones that get little critical review and little attention.

   Areas like HR, support, or sales, which are often forgotten when people think about the attack surface, become easy targets. As technology awareness has grown, these departments have turned into quick entry points for fraud and for stealing information or credentials.

4. Skills
   Communication may be the most important skill, and the most underrated. To drive improvement, you have to understand people and processes, negotiate, handle office politics, be patient, build alliances and get people to “play on the same team.”

   I’ve come to value soft skills much more than hard skills. These days, technical knowledge is relatively easy to learn. Attitude, commitment and communication depend on personal initiative.

   This directly affects how successfully security processes get implemented and maintained.

5. Challenges
   The challenge is much bigger than I imagined at the start. Sometimes it’s frustrating. Sometimes it’s exciting. Along the way I’ve laughed, I’ve cried, I’ve thought about quitting, and I’ve also felt like taking over the world.

   The demands seem endless, and to survive I had to learn to prioritize and accept that I won’t be able to meet every need.

   If you don’t know what you don’t know, you risk falling into the trap of arrogance and assuming everything is secure. I learned (and keep learning) that there are no miracles: it takes conversation, pulling up a chair, watching how the work gets done and learning to ask the right questions. That may be the biggest challenge, but it’s also what sets you apart when it comes to identifying critical risks.

   Communication again. The message has to fit the audience: what you present to senior leadership isn’t what you present to HR, to administration or to the development team.

6. Management and prioritization
   I had to learn to understand what creates the most value and to rank things, so that limited effort goes to what matters most and has the best impact.

   Other methodologies already apply this idea. Scrum, for example, with the 80/20 principle.

   Transparent organization and documentation are important for minimizing blind spots and keeping the focus on the highest-value activities.

7. ISO 27001 and other frameworks
   Supporting frameworks always help. They’re great for covering areas you don’t know or aren’t familiar with.

   Best practices documented in references like ISO, OWASP and NIST give solid direction and keep you from falling into the trap of making decisions on gut feeling.

Security is a process, and it’s cyclical.
It’s not a product.
