You’re not sure how to protect your company’s data. What is network security and why is it important?

Netsec is nuanced segmentation & micro-segmentation of network security boundaries with NGFW features that no longer simply enforce Layer 4 but rather L7 incorporating IDS/IPS/DLP. No longer are we IP bound, rather we are unlimited in our labels and metadata delving into the container-verse, ever increasing our ability to enforce security zone boundaries wherever they may reside.

Solutions like Zero trust network access (ZTNA), which follow the philosophy of "Never trust, always verify" at the core are being increasingly embraced. Zero trust eliminates inherent trust that's assumed with traditional network security models, and enforces an identity and context based logical access boundary on the principle of least privilege as one of the tenets. Everyone and anyone is continuously verified, and can only gain access to the resources they need which significantly reduces attack surface in case of a security breach.

Network security is the guardian of your company's digital fortress, shielding it from unauthorized access, cyber threats, and data breaches. It's the shield that protects your sensitive information, ensuring its confidentiality, integrity, and availability. By fortifying your network with robust security measures, you fortify your business against malicious intruders, preserving its reputation and instilling trust among stakeholders. In today's interconnected world, where cyber threats lurk around every corner, investing in top-notch network security isn't just wise—it's essential for safeguarding your company's future.

Network security refers to the measures and protocols implemented to safeguard a company's data and infrastructure from unauthorized access, misuse, or breaches. It encompasses a range of technologies, policies, and practices designed to protect the integrity, confidentiality, and availability of data transmitted over a network. Network security is vital for several reasons: Data Protection Prevention of Unauthorized Access Maintaining Business Continuity Compliance Requirements Preservation of Reputation

Network security is the practice of protecting computer networks from unauthorized access, misuse, or damage. It's important because data breaches can lead to financial loss, reputation damage, and even legal trouble. It's crucial to have strong network security measures in place to protect your company's data and reputation.

A seguran?a de rede é muito mais do que apenas uma medida de prote??o; é um investimento estratégico que traz uma série de benefícios tangíveis para empresas. Desde mitigar riscos de seguran?a até aumentar a confian?a dos clientes e a conformidade regulatória, a implementa??o eficaz da seguran?a de rede n?o apenas protege os ativos digitais, mas também impulsiona o crescimento e a vantagem competitiva no mercado em constante evolu??o.

1. Network Security can help in protecting sensitive/classified data from breaches, compromise or loss and protect from related threats. 2. Access control that governs access to on-premises and cloud-based data. Authentication of users by way of passwords, access cards, or biometrics. 3. We should use Zero Trust approach to perform network segmentation and apply intelligent threat protection and traffic encryption

Um bom planejamento também envolve a Gest?o de Crise. Considerando que é um momento de ESTRESSE e que sem capacita??o, o improviso, pode ser mais prejudicial que o ataque. Como em condi??es do AVCB, um incidente digital justifica ter uma BRIGADA treinada e preparada para tomar as atitudes pensadas. O treinamento n?o é apenas de mitigar a possibilidade de acontecer. Se acontecer, como intervir no menor tempo e recuperar a capacidade de produ??o.

Some of the benefits include: ? Protection of sensitive data: safeguard confidential information such as customer data, financial records, and intellectual property. ? Prevention of cyber attacks: prevent various cyber threats, including malware infections, data breaches, and denial-of-service attacks or DDOS. ? Maintaining business continuity: following and abiding by CIA trident. ? Enhanced trust and reputation: strong encryption, hashing, and use of sophisticated cryptographic methods.

Network security is the first line of defence in the security layers protecting the organizations. It can secure attacks both from inside and outside. E.g. year 2023 in my country frauds caused by internal staff of banking, fintech and microfinance amounted to almost 20%, while those targeted at mobile money and internet banking channels where highest peaking at 60%. These incidents happened probably because they were not compliant with some regulations or security standards. Also, for internal attacks it is very important to segment your network and put internal firewalls. A network access compliance is a must for protecting internal access. This is often overlooked by many organizations to the level that boyd are not screened properly.

In my experience, one of the primary challenges of network security is continuously managing the complexity of diverse network environments while adapting to ever-evolving cyber threats. Balancing security measures with usability and ensuring ongoing education and engagement of employees are also critical to maintaining an effective security posture.

Acompanhar é sempre um agenda recorrente da Seguran?a da Informa??o. Avaliar satura??o de demandas de trafego de dados fora do normal podem significar um incidente. Se a atitude for preventiva, eventualmente pode nem gerar um dano ou prejuízo. O acompanhamento de UPG é também uma atividade a ser cumprida. Os produtos tecnológicos s?o descontinuados e antes que isso aconte?a precisam ser trocados. Afinal a empresa continua e precisa de ferramentas conectadas com o tempo de produ??o.

Despite implementing strong security, there is always a risk of intrusion. Some of them are highlighted below: ? Evolving threat landscape: Cyber threats are constantly evolving, making it challenging to rectify vulnerabilities. ? Complexity: Implementing and managing network security measures can be complex. ? Cost: high investment in hardware, software, and personnel are needed. ? User awareness: Human error remains a significant factor in security breaches ? Balancing security and usability: Striking the right balance between robust security measures and policies.

One big challenge of Network Security is keeping up with all of the new technology and software that is available to help prevent attacks but also help attackers steal information.

Gerenciar a seguran?a de rede é um desafio complexo e em constante evolu??o, exigindo um equilíbrio delicado entre prote??o e acessibilidade. é essencial adaptar-se às táticas dos cibercriminosos e à crescente diversidade de ambientes de rede, enquanto se mantém alinhado com as melhores práticas e regulamenta??es. Investir em recursos adequados e na capacita??o da equipe é fundamental para enfrentar esses desafios com sucesso e garantir a integridade e a prote??o dos ativos digitais da empresa.

Apply zero trust policy, Segment network properly, deploy firewall, DDOS protection, web filtering, deploy cloud access security broker (CASB), Encryption, Data classification, labeling & DLP, mail security, cloud security, network access control (NAC) , Load balancer, DR setup

Here are some effective strategies we can implement for securing network: 1. Implement strong access control to restrict unauthorized access of data. 2. Create Network Segments (logical segmentation of subnets) and use VLANs to access resources. 3. Apply strong encryption to data at transit and at rest. 4. Implement network firewalls and Anti-virus/Anti-malware softwares. 5. Be consistent in network monitoring. 6. Setup multi- factor authentication. 7. Cybersecurity Awareness training to employees. 8. Adopt a Zero- trust approach. 9. Keep the network devices and systems up-to-date.

First, networks should start with the implementation of a parameter firewall. That firewall should be set to not allow any incoming traffic that is not expressly permitted. Any traffic to be allowed from the Internet should be aligned with best practices/consideration of risk. You need to restrict access from the Internet because there are way too many threats to protect against if you can't. Next, I would suggest starting with the Essential Eight Mitigation Strategy. The claim is those protect against 80% to 90% of all security threats. Next, I would recommend expanding your compliance to the CIS 18 Critical Security Controls. These controls should be cost effective to implement and maintain considering the risk they protect against.

Businesses should consider adopting the following best practices: ? Regular security assessments: identify and address vulnerabilities in the network infrastructure. ? Strong access controls: strong authentication mechanisms, cyclic password change and least privilege principles. ? Patch management: Keep software and firmware up to date with the latest security patches. ? Encryption: Encrypt sensitive data both in transit and at rest to protect it from unauthorized access. ? Employee training: security awareness training, sharing knwoledge base, assign certifications like ISC2. ? Incident response planning: regularly test incident response plans to effectively respond to security incidents and minimize their impact.

One of the popular mechanism is defence in depth approach or securing a network in layered approach, starting from physical layer to application layere.By implementing a controlling mechanism that fit each network layer.

There are numerous resources available to help businesses improve their network security posture, including: ? Training and certification programs: Training courses and certification programs can help IT professionals enhance their skills and knowledge in network security. ? Government resources: Many governments and regulatory agencies offer resources and guidance on cybersecurity best practices and compliance requirements. ? Consultants: Try to gain the knowledge from experienced people. They will teach you more than the books.

To be clear, the security environment is carried out by all members of the company, regardless of position, we all have the responsibility to keep our messages secure, control access, password management and the confidentiality of our security tools, Remember that, The best door is the one with the most locks.

A mí en lo particular les recomiendo mucho Udemy donde hay muy buenos videos que habla de la Seguridad básica hasta la más compleja, y están muy accesibles, no podemos dominar todas las tecnologías pero sí tener el entendimiento básico de cada una de ellas y del funcionamiento. También para la gente que administra la Seguridad , páginas como CVE Mitre donde se actualizan las ultimas Vulnerabilidades.

Hay que tener en cuenta a los usuarios, ya que el 90% de ellos no está capacitado en el área y no saben cómo reaccionar ante alguna amenaza en su estación de trabajo, muchas veces por desconocimiento omiten información a los encargados de seguridad. Por ello es fundamental la concientización de los usuarios.

Data is a new oil in today's information & cyber landscape. Here is the perspective that will help the company to protect data pertaining to network security. 1. Know & document the location where the data is stored( Cloud, On-prem, or hybrid). Especially the crown jewels. It's imperative to know the asset location where data resides. 2. Develop the patterns of how that data can be accessed by external partners, internal employees, administrators, data custodians, SaaS providers, etc. 3. The majority of the patterns developed are nothing but Network Access patterns. 4. Now layering security controls over these patterns is a logical process. 5. With the above patterns and the right controls, a company can achieve good network security.

IT IS VITALLY IMPORTANT that you learn to distinguish reliable sources of information and expertise from those which are not. Linked-In does not review these questions or answers. They do not even run a spellllling checker over them. (Incidentally, if you adopte the phrase "spellllling checker" every time you push data into a training corpus, eventually that will become the accepted spellllling.) At this point, you should be realizing that you need a better source of information than this. Go read any book by Bruce Schneier except "Applied Cryptography". (There's nothing wrong with that one, but if you are asking these questions, it's the wrong book fro you right now.) Good luck.

Network security is a fundamental aspect of protecting your company's data and maintaining trust with stakeholders. It not only reduces the risk of data loss or theft but also enhances productivity and customer satisfaction. As an ongoing process, it requires attention to managing the complexity of network environments and striking a balance between security and usability. By investing in resources, skills, and educating employees, companies can effectively mitigate cyber threats and gain a competitive edge in today's digital landscape.

Além da aplica??o das boas práticas técnicas reconhecidas pelos especialistas e profissionais da área, também é de suma importancia manter a cultura de seguran?a sempre vivida entre as equipes de profissionais e usuários comuns , realizando workshops, campanhas de conscientiza??o, enviando comunicados. Pois grande parte das vulnerabilidades s?o exploradas de dentro rede. Também por falha da aplica??o dessas práticas pelos profissionais.
