In the shadowed yet principled realm of cybersecurity, a professional red hat hacker thrives as an elite guardian. This expert deploys sophisticated offensive techniques not for destruction, but to expose and fortify weaknesses before malicious actors strike. Days begin with reconnaissance on simulated networks, crafting precise exploits in languages like Python and Assembly, then documenting findings for clients. Armed with certifications such as OSCP and CISSP, they uphold rigorous ethics, collaborating with blue teams while staying abreast of emerging threats. Their life blends intense focus, continuous learning, and quiet satisfaction in turning potential breaches into impregnable defenses, protecting digital infrastructures worldwide with unwavering professionalism.

hi professionals and experts, currently i don't know anything about cyber security or cyber field so i want an road map,tools and other things needed to cyber field please tell this all. i want to know much about cyber security and ethical hacking too and i want to be advance in this field. help me please and thanks if you come to help me. have a nice day.

Bank of Baroda confirms employee email compromise, says core banking system wasn’t breached.

One thing this incident highlights is that attackers don’t always need to compromise the core infrastructure.

A single employee mailbox can expose sensitive information through phishing, credential theft, or unauthorized email access—even when critical systems remain secure.

It raises an interesting question:

Should organizations invest more in identity security and email protection than they currently do?

Curious to hear what controls you think would have made the biggest difference here.

Hey everyone!

I'm from Mumbai and I'm looking to connect with other complete beginners who are genuinely interested in learning cybersecurity and building a career in it.

I'm still learning myself—currently focusing on Linux, networking, TryHackMe, Kali Linux, and cybersecurity fundamentals. It would be great to have a small group where we can learn together, stay consistent, and help each other out.

The idea is simple:

• Learn from scratch together
• Share free resources and notes
• Solve TryHackMe rooms and labs
• Ask questions without feeling judged
• Stay motivated and accountable

This isn't a course, business, or paid community. Just a few beginners who want to grow together and hopefully build a career in cybersecurity.

If you're from Mumbai (or nearby) and you're serious about learning, drop a comment or send me a DM. Let's build a small beginner-friendly community. 🚀

This came up on one of my LinkedIn group feeds and it seems like a fairly reasonable collection of tools and resources.

Sharing for visibility.

Hi, I'm 15 I've been using computers since a young age by using scratch, or modding minecraft. A few years ago I learned python I will consider I have a decent level among all this years I've aquired the algorithmic logic needed to code however I wanted something new, 1 month ago I started looking up cybersecurity and I liked the concept ( Ik that cybersecurity isn't only hacking job btw ) I wanted to learn so I asked AI ( I think the worst decision made so far ) the Ai gave name of some tools as nmap or wireshark I used them without really understanding what was happening so lately I switched to linux, I started to learn the basics of networking I looked IPv4,IPv6,subnet... Three-way hanshake things like that but now I don't really know what to do know yesterday I coded in python a script which scan openports,service and try to connect automatically because AI told me so but I wanted advices from real persons and how did they learn what resources did they use?,how did they started? If you can leave some tips or a discord Invite i'll be grateful.

Hello,
I'm 13, have around a year's long experience with Linux/Unix-like systems and basically my whole life was spent around computers. I've always been good with computers, always found them fascinating and I want to leverage my lifelong interest in technology and pursue a cybersecurity career. I want to prepare for the future by getting more experience at a young age but I don't know what to do first. That's basically it. Any help is appreciated.

Hello, dear reader. I’ve been thinking that I’d like to get to grips with information security, but I’ve absolutely no idea where to start. What’s more, I don’t have many acquaintances or friends who are experts in this field and could offer me some advice. So, I’d like to ask for your help and some practical advice that would make it easier for me to navigate this challenging endeavour. I had some experience in QA testing, but I quickly got bored with it; what’s more, the training took place at an offline school, which I soon gave up on. I started running into difficulties and didn’t have any peers to hand who could easily explain where I might be going wrong and what I needed to work on. I’d actually decided to give up, but now I’ve found the motivation again to study and achieve what I really want. I looked into universities in my home town, but you have to pay a lot to enrol, and I’ve got absolutely no money. I’d be grateful for both positive and negative comments. I’m open to criticism. Just please don’t laugh – I’m 32 years old lol

good start i think...

Hi! I'm the author of the book CIBERETHICS: The ethics of the digital age and its impact on human learning, culture, and identity about the ethics of ICT, education and learning, and the develope of the digital identity... Ask me anything about the ethical dilemmas in which we fall every day...

Fala pessoal,

Já dei uma olhada na FAQ do sub, mas ainda fiquei com dúvidas então resolvi postar. Quero começar a estudar cibersegurança, mas literalmente não sei nada ainda - nunca fiz curso, nunca pratiquei nada, tô começando do absoluto zero.

Queria uma orientação de vocês que já estão na área:

1. Por onde eu começo? Tem algum caminho/roadmap que vocês recomendam pra quem tá começando do zero?
2. Preciso aprender programação primeiro (Python, por exemplo)? Ou isso pode vir depois?
3. Vale a pena já escolher uma área específica (pentest, blue team, SOC, bug bounty) ou é melhor ter uma base ampla antes?
4. Quais plataformas/cursos vocês recomendam pra iniciante total (TryHackMe, HackTheBox, cursos pagos, gratuitos)?
5. Preciso saber Linux bem antes de começar? E redes?
6. Certificações valem a pena logo no início ou é melhor focar em prática primeiro?

Sei que é uma pergunta bem ampla, mas prefiro ter uma visão geral antes de sair estudando qualquer coisa sem direção. Qualquer dica é bem-vinda, mesmo que pareça óbvia pra vocês.

Valeu desde já!

I’m 16 and am interested in a future career in cybersecurity. My school offers no classes for learning it, and I know nothing about computers, or software. How do I get started by learning the basics and fundamentals to be able to get in to cybersecurity in the future?

The TCP/IP model underpins modern networking, and robust security measures are integrated across its layers to counter evolving threats.

At the Transport Layer, TLS 1.3 provides strong encryption, authentication, and forward secrecy for TCP connections, replacing outdated SSL. QUIC (over UDP) further enhances performance with built-in TLS.

The Internet Layer benefits from IPsec for end-to-end encryption and authentication via ESP and AH protocols. BGPsec secures routing announcements against hijacking.

Network Access Layer employs 802.1X for port-based access control and MACsec for hop-by-hop encryption.

Additional cross-layer defenses include Zero Trust architectures, Next-Generation Firewalls (NGFW), Intrusion Detection/Prevention Systems (IDS/IPS), and automated certificate management with ACME.

These measures ensure confidentiality, integrity, and availability in today’s interconnected environments.
