A security specialist in general is someone who deals with performing or implementing detection of threats and vulnerabilities and/or prevention of general or defined risks. Their specialization depends on their experience on the kind of industry they work in. A regular day may involve risk assessment, threat modelling and device manual or automatted approach to verify attack scenarios. Based on these, they suggest solutions. Sometimes they might have to validate reports from external auditors or public programs, sign off new features or enhancements. A good security specialist will have complete knowledge about the systems/infrastructure they're working on. Some of them are great at identifying threats by reviewing the architecture.

A Computer Security Specialist requires a robust skill set to navigate the dynamic cybersecurity landscape. Proficiency in frameworks like MITRE ATT&CK and NIST is essential, complemented by education from top institutions like CMU, MIT, and Stanford. Certifications such as CISSP, CEH, and OSCP validate expertise. A deep understanding of threat modeling, including assessing zero-day vulnerabilities, countering insider threats, and combating ransomware, is vital. Awareness of quantum computing's hacking implications and government-sponsored hacking groups is crucial. Skills in hypothesis testing and threat modeling contribute to a holistic approach to fortifying cybersecurity defenses.

Besides the technical skills, a computer security specialist must have very strong communication abilities. At the end of the day, the specialist will also need to translate technical security requirements or actions into simple (business) language, and this is no simple job at all.

En mi humilde opinión, aparte de tener unos conocimientos técnicos bastante versátiles y que la mayoría de colaboradores ya mencionan son importantes: - La adaptabilidad - La capacidad de resolución de problemas - La capacidad de comunicar información técnica al personal no técnico, si es posible en varios idiomas. - Y lo que yo considero más importante, trabajo en equipo, ya que siempre habrá un compa?ero o varios que aporten lo que a ti te pueda faltar.

Computer security specialists typically are involved in day-to-day management of network security hardware and software, as well as in supporting various aspects of technical, installation, operational and performance operations. but some common responsibilities, include: Troubleshooting server and network security-related issues Designing, implementing and testing compliant network security systems and solutions Maintaining security infrastructures Drafting technical documentation and security guidelines Collaborating with management, staff, department heads and external partners or regulators Developing business continuity and disaster recovery plans

The cybersecurity landscape poses challenges requiring continual adaptation. Zero-day vulnerabilities and insider threats are ever-evolving risks, alongside ransomware attacks and cyber warfare. Constant vigilance is paramount. Opportunities include enhancing cyber awareness, fostering public-private collaboration, and investing in quantum-resistant encryption. Governments must fund initiatives combating hacking groups, particularly those targeting critical infrastructure like OT networks, SCADA, DCS, and smart vehicles. Mitigating human errors through improved cybersecurity training and raising awareness about critical environmental risks are integral to addressing these challenges.

Computer security specialists face challenges in staying ahead of evolving threats, adapting to new technologies, and addressing the constantly changing cybersecurity landscape. On the flip side, opportunities arise from the increasing demand for skilled professionals in response to growing cyber threats. The dynamic nature of the field provides specialists with chances for career growth, specialization, and contributing to the overall enhancement of cybersecurity measures in organizations.

I agree with Razieh, I think one of the biggest challenges is keeping up with the changes. The cyber world changes so fast that we have to be open to changing course and stay adaptive every day. Understand the threats, what they mean to us and act to stay safe. It's always a balancing act of cost verses benefit and someone will need to make the call on how much to spend (act) against the threat. Clear assessment of risk is essential, to do that you have to understand your environment as well as the new threat. That's a tough job for anyone.

Um dos principais desafios é a crescente sofistica??o dos ataques cibernéticos. Com a transforma??o digital acelerada pela pandemia, as empresas est?o mais expostas a esses ataques, especialmente porque os criminosos digitais est?o constantemente mudando suas táticas. Além disso, cada dispositivo conectado é uma potencial porta de entrada para um ataque cibernético, aumentando a complexidade da prote??o da seguran?a.

Challenges: 1. Constantly Changing Threats: Keeping up with evolving cybersecurity threats is a challenge. 2. High Stakes: Security breaches can have severe consequences, leading to high-pressure situations. 3. Skills Gap: There's a shortage of skilled professionals, creating a competitive job market. Opportunities: 1. High Demand: There's a strong demand for cybersecurity skills, offering excellent career prospects. 2. Diverse Specializations: The field offers various specializations, allowing individuals to find their niche. 3. Continuous Learning: The dynamic nature of cybersecurity provides opportunities for ongoing learning. 4. Competitive Salaries: Professionals in cybersecurity often enjoy competitive salaries and benefits.

Imagine a scenario where you, as a lead CISO in a top network oil and gas environment, detect traces of a cyber-attack originating from Germany. The hackers, exploiting default passwords, are on the verge of gaining access to the router and are dangerously close to infiltrating the Programmable Logic Controller (PLC). Utilizing MITRE ATT&CK techniques, promptly address the situation by enhancing router security, implementing multifactor authentication, and deploying threat detection mechanisms. Implementing strategies to secure the PLC, such as adopting a zero-trust framework and regular security audits, becomes crucial to prevent a potentially catastrophic scenario.

Some things that only security teams can relate. 1. They know a lot of confidential information about and inside the organisation (new features, architectures, attacks, exploits, incident analysis) but they should never talk about it. 2. They enforce the security policies. So even if its them or their friends at work. They have to follow those policies or SOP, no matter how uncomfortable it may make you or your friends. 3. They usually run on smaller budget than rest of the org (or atleast within IT). It's no global secret anymore. 4. No matter how hard you invest in awareness or training. People always click those links from spooky emails or SMS. So improve your access management, and enforce policies if your IAM or IDP allows for it.

A cyber or computer security specialist is someone that understands the mission, vision, values of the organization to then apply risk-based professional judgement when implementing controls (safeguards) and managing associated risks. This happens (or should) regardless of the cyber domain this person performs their function. The best specialists practice what they preach, have the heart of teachers to help others, and consistently drive risk-based implementations.
