A continuación, le indicamos cómo puede evaluar el impacto potencial de sus decisiones en la seguridad del sistema.

For COTS software, sourcing information relevant to the changes you wish to make is crucial. Finding drawbacks experienced by others will allow you to side step potential pitfalls. For proprietary or locally generated software, a mature, robust development/test environment, unit and regression testing, and a mature Change Management DB are key.

Analysis is always crucial when it comes to any new beginning. So it is better to have a best practise setup for evaluating and avoiding risk elements. Have an approved or examined software inventory list. Keep your organization systems with upto date patch fixes and always ensure it is under compliance.

No matter how much you want to make your system secure, it will have vulnerabilities. It doesn't matter who writes your code, artificial intelligence or a human - this code will not be perfect. But you can and should to reduce the risks through training your staff or timely software updates. If you need help and you are making a web service, you can ask Crunch.is specialists. If you want to go into the vulnerabilities of the software, then it is better to do it through the services of the SOC Prime company. Better safe than sorry.

Always choose virtualization to try outs if possible... And if Not possible, make sure the try out is done after the weekly full backup, outside working hours. All of this should be done after having done research about the new software methods and compat

I faced a critical Azure VM outage during peak hours. Diagnosing the issue quickly, I identified a misconfiguration in the network security group, implemented a fix, and restored services. Continuous learning and networking are key. Staying updated with Azure certifications and participating in webinars have been essential. Soft skills like communication and teamwork are crucial for managing Azure-based projects and resolving cloud-related issues. Automation in Azure is impactful. Using Azure Automation to create runbooks for routine tasks reduces errors and improves efficiency. Implementing Azure Backup and Recovery Services ensures data integrity and business continuity.

Use the CI/CD tool set for change control and promotion of code changes. full automation for approvals otherwise the change cannot promote to production. More intelligence can be added with AI insights to the tool set. I am envisioning a big change in coming years.

Implementing changes in a production environment requires robust change management processes. Establish clear procedures for requesting, reviewing, approving, and implementing changes. Documenting every step ensures accountability and facilitates tracking changes for auditing purposes. Additionally, define roles and responsibilities within the change management team to streamline communication and decision-making. Regularly review and update change management processes to adapt to evolving business needs and technologies.

Add to this Change Management enforcement with tools like TripWire, or Ansible/Puppet/Windows DSC, and your well on your way to ensuring changes happen only when desired.

Viele Wege führen nach Rom. Wichtig ist, dass man sich auf den Weg macht. So oder ähnlich könnte man das sehen, was ich damit sagen will - Ein Servicehandbuch, change-log oder lückenloses auditing ist nur so gut wie man es ausfüllt oder einrichtet. Wichtig ist, dass man seine gut überlegten Änderungen auch festhält. Es muss kein Referat geschrieben werden, einfach simple Dinge wie Wer/Wie/Was/Warum genügen, wichtige ist einfach nur es IMMER zu beachten. Fehler passieren in einer schnelllebigen Zeit, hat man Dokumentiert gelingt es auch Fehler wieder rückgängig zu machen.

Ou mettre en place differents environnements iso pour effectuer des tests en hors production avant production. Egalement prevoir des rollbacks.

Die Möglichkeiten einer Testumgebung ersparen einem viele potentielle Probleme. Ein festhalten der Abläufe in einer Testumgebung erleichtert das umsetzen der changes an der produktiven Umgebung sehr. Leider ist das ein Punkt bei dem sich viele ITler oftmals zu wenig Zeit nehmen oder Zeit zur Verfügung gestellt wird.

La simulación de los servicios en entornos de prueba facilita el estudio de los próximos cambios que va a sufrir el entorno de producción, ayudándonos a entender los posibles fallos en las nuevas implementaciones e intentar corregirlos o realizar los cambios necesarios antes de que se lance como entorno de producción.

Creating test environments that closely mirror production and operation of systems is a practice I have honed through my work on UAV systems and avionics. Before rolling out any changes, extensive testing is conducted in a controlled environment to ensure no new vulnerabilities are introduced. This process includes unit testing, integration testing, and regression testing. Establishing different environments for testing and ensuring thorough documentation of test procedures can prevent potential issues when changes are moved to production. Detailed test plans and checklists ensure that every aspect of the change is thoroughly vetted before deployment.

Testing protocols are vital for system administrators to ensure system reliability and performance. Clear objectives, appropriate methodologies, realistic test environments, thorough documentation, and adaptability are key elements of effective testing. By implementing robust testing protocols, system administrators can identify and address potential issues, safeguarding the reliability and performance of IT systems.

Die Einholung der Erkenntnisse Ihrer Kollegen bietet wertvolle zusätzliche Perspektiven auf die potenziellen Auswirkungen Ihrer Entscheidungen. Im Rahmen eines Peer-Review-Prozesses prüfen sachkundige Personen Ihre vorgeschlagenen Änderungen. Dabei können sie potenzielle Probleme identifizieren, die Sie möglicherweise übersehen haben, und alternative Lösungen vorschlagen. Dieser kollaborative Ansatz erhöht nicht nur die Sicherheit Ihrer Systeme, sondern fördert auch eine Kultur der gemeinsamen Verantwortung unter den Teammitgliedern. So profitieren alle von einem sicheren und kooperativen Arbeitsumfeld.

Kollegen ersetzen einem nicht das Denken, sie helfen ggf. Ansichtspunkte zu erkennen, die man im aktuellen Setting teilweise gar nicht hat. Verschiedene Sichtweisen und produktives, kollektives schaffen am System ist eine Bereicherung, nicht nur für die Systeme oder die Kunden... sondern auch für einem selbst.

La sincronización entre los miembros del equipo técnico puede llevarnos a tener una mayor percepción de los problemas que puedan surgir y tener esa consciencia colectiva nos ayudara a tener una visión lateral diferente.

Peer review has been integral to my work, particularly in collaborative projects involving design and testing of aerospace systems. By involving colleagues with diverse expertise, we can identify potential issues that might be overlooked by a single individual. This collaborative approach not only improves the quality and security of our systems but also fosters a culture of shared responsibility and continuous learning.

Peer review is indispensable in system administration, offering error detection, knowledge sharing, and accountability. By adhering to established guidelines and providing constructive feedback, system administrators can maintain quality and consistency in their work, ultimately leading to more reliable and secure systems.

Continuous monitoring in security is vital in ensuring a robust security program. Often times when tools have a lag of reporting, this slows the ability for teams to adapt and address issues as they arise. Education of the importance of risk and their lack of easily digestible and accurate information also slows efforts in adapting to an ingrained security posture and mindset in software and systems delivery. Shifting left as far as possible will get you about 75-90% there. But it’s the use cases that people don’t account for, like zero day vulnerabilities and hacker attacks, that require extra automated and orchestrated deployments to address the threats expediently. AI and ML can help in this effort, but models need to be fine trained.

Guter Rat ist wertvoll, ein gutes Monitoring noch wertvoller! Es geht im Dasein eines IT Dienstleisters eigentlich nichts darüber, bereits vor dem spürbaren Auftreten von Problemen, bereits im vorneherein davon zu wissen. Leider ist gutes Monitoring ein zartes, filigranes Pflänzchen dass gut gepflegt und getestet sein will. Es ist teilweise schwierig zu implementieren aber wenn's denn geklappt hat, möchte man es nie mehr missen.

Regular audits and reviews of system logs and engaging in proactive monitoring allows for the swift isolation and mitigation of potential security breaches before they escalate.

Debemos hacer revisiones periódicas de las implementaciones realizadas ya sea utilizando software específico de monitoreo o revisando los simples log´s, de esta manera podemos tener una mayor idea de que esta ocurriendo en nuestros sistemas y si las implementaciones han salidos bien

Continuous monitoring after implementing changes is crucial, especially in high-stakes environments like aerospace. We utilize advanced monitoring tools to track system performance and system logs, ensuring any abnormal activities are detected promptly. Establishing baseline metrics before changes allows for effective comparison and quick identification of issues. This proactive approach ensures that any detrimental impacts are swiftly addressed, maintaining system integrity and security. Regularly reviewing logs and using monitoring tools helps in early detection and resolution of any issues that may have escaped testing.

Die Aktualisierung Ihrer Dokumentation nach Änderungen ist entscheidend für die Systemsicherheit. Stellen Sie sicher, dass alle relevanten Dokumente, wie Systemkonfigurationen, Benutzerhandbücher und Sicherheitsprotokolle, die letzten Änderungen widerspiegeln. Eine genaue Dokumentation ist wertvoll für die Fehlerbehebung, zukünftige Audits und informiert alle Teammitglieder über den aktuellen Systemzustand. Aktuelle Dokumentation minimiert das Risiko von Sicherheitsverletzungen aufgrund veralteter Informationen oder Verfahren und trägt zur langfristigen Sicherheit und Effizienz Ihres Systems bei.

Let's make sure the run books are also updated been there done that. Yup, your the sole person that knows what you did to fix it or updated an script. That means at 3am your getting the call and you co-workers are going to be not so happy reverse engineering what changed and why. So if there is a Content Management System or what have you be sure to make notes when someone makes a change. It can mean five minutes versus an hour or more to solve an issue. Remember 3-6 months later when it happens again you'll have to reverse engineer what you did.

Furthermore, version control should be employed to track changes and maintain historical records of documentation updates. Regularly review and validate documentation for accuracy and completeness to avoid discrepancies that could lead to security vulnerabilities. Engaging all team members in the documentation process ensures comprehensive coverage and fosters a culture of accountability and continuous improvement.

Assess potential risks, identifies threats and vulnerabilities, analyzes potential consequences, benefits, and continually monitors for the security threats. Cost considering

Perform "what-if" scenarios to anticipate security impacts under different conditions.Engage external security experts or consultants for unbiased reviews.Implement bug bounty programs to incentivize independent researchers to report vulnerabilities.Engage in ethical hacking to uncover security weaknesses via penetration testing and analyze user behavior patterns to detect anomalies indicating potential threats with User Behavior Analytics.

En los tiempos que corren, cada vez es mas necesario las tareas de red y blue team para conocer el estado de los servicios de cara a la ciberseguridad, tener una mentalidad abierta y un buen plan de respuesta es fundamental, no podemos tener la mentalidad de que nunca nos van a hackear, mas bien debemos tener una mentalidad y pensamiento de como actuaremos cuando nos hackeen. La formación del usuario final es clave para evitar brechas de seguridad ya que el humano sigue siendo el eslabón mas débil de esta cadena llamada informática.

Assessing potential impact requires a mix of foresight and flexibility. Look ahead to predict outcomes, but be ready to adapt your strategies as situations evolve.

How about an unannounced Penetration Testing to see the vulnerabilities the security of their network and which areas are vulnerable including their E-Mail, Gateway, Database procedures and others like dismissed former employees, disgruntled former employees, higher ranking employees with access to backdoors into the Network System including Network Operations, former C.I.O.s, Database Dept., Finance Operations and others. Backup plans and operations, Business Continuity Planning, ERP, etc.
