Here's how you can effectively manage and mitigate cyber threats to your business in network security.

In an increasingly digital world, network security is paramount for the protection of your business. Cyber threats are evolving, becoming more sophisticated, and can originate from anywhere across the globe. As a business owner or network administrator, you have the power to shield your company from these potential attacks. Effectively managing and mitigating cyber threats involves a proactive approach, from understanding the risks to implementing robust security measures. The following strategies will guide you in fortifying your network and safeguarding your business assets.

1 Risk Assessment

Understanding the specific risks your business faces is the first step in network security. Conduct a thorough risk assessment to identify vulnerabilities within your network. This means evaluating all the components, such as routers, switches, and servers, for potential weaknesses. Also, consider the human element—employees can unwittingly become the weakest link in your security chain. Once you have mapped out where your system might be compromised, you can prioritize these areas for immediate attention.

Proper planning and preparation are key to success. Architect your network designs so that security is at the heart of the plans. Much like the layout of a medieval castle or a bank, identify, isolate and fortify your network defences using a layered approach (aka Defence in Depth (DiD)) to isolate your important business systems from the less important environments. Prioritise the remediation of any identified vulnerabilities, based on actual the perceived risks. Ensure that your SOC has an awareness of the network designs. That way, long before an opportunist attacker has the chance to compromise your most important business services, there's an increased chance of their ABNORMAL activities having been identified and responded to.

Identify all critical assets, including hardware, software, and data. Identify potential threats and vulnerabilities to organization’s network environment. Assess the likelihood and impact of identified threats to prioritize mitigation efforts. Implement Strong Network Security Controls as Firewalls/NGFW, IDS/IPS, Network segmentation. Implement Access Control as Role based access, 2FA/MFA. Have patch management process for all assets. Continuous Monitoring and Threat Detection using SIEM, Threat Intelligence.

Think like a realist. Always think that your corporate network will get compromised and then plan and prepare for such an eventuality. - Employees are human, they make mistakes: 1. Anticipate. In the event of a compromised network, how can you limit the impact? 2. Withstand. How quickly can you return your Important Business Services to normal operations? How often do you test your capabilities? 3. Recover. What risk responses are applied, following a capabilities test or actually incident? Are you able to modify your business operations to mitigate any emerging threats? 4. Adapt.

2 Policy Creation

After identifying potential risks, develop a comprehensive security policy tailored to your business needs. This policy should outline acceptable use of network resources, password protocols, and guidelines for internet and email usage. Educate your staff on these policies to ensure everyone understands their role in maintaining network security. Regular updates to this policy are essential as new threats emerge and technologies evolve.

3 Access Control

Limiting access to your network is a critical component of security management. Implement strong user authentication mechanisms to ensure only authorized personnel have access to sensitive information. Utilize multi-factor authentication (MFA) for an added layer of security, which requires users to provide two or more verification factors to gain access. Furthermore, regularly review user permissions and modify them as necessary to minimize the risk of internal threats.

4 Regular Updates

Keeping software and systems up to date is a vital defense against cyber threats. Hackers often exploit known vulnerabilities in outdated software. Ensure that all systems are patched with the latest security updates from vendors. Automate this process where possible to reduce the likelihood of human error. Additionally, upgrade your hardware components periodically to benefit from advancements in technology that provide enhanced security features.

5 Monitoring Systems

Continuous monitoring of your network can detect suspicious activities before they escalate into serious incidents. Deploy intrusion detection systems (IDS) and intrusion prevention systems (IPS) to monitor network traffic for signs of anomalies or malicious activities. Set up alerts so that you are notified immediately of any potential breaches. Regularly review logs and patterns to adjust your security measures and respond to new types of attacks.

El monitoreo debería implementarase no solo como un elemento reactivo (cuando la amenaza se materializa). Establecer mecanismos de identificación de amenazas en etapas tempranas del ciclo de vida de los servicios es vital para poder definir patrones de comportamiento y vectores de ataque.

6 Incident Response

Even with robust security measures in place, breaches can occur. Be prepared with an incident response plan that outlines steps to take when a security incident is detected. This plan should include containment strategies, eradication of threats, recovery processes, and communication protocols with stakeholders. Conducting regular drills can help ensure that your team is ready to act swiftly and effectively in the event of a cyber attack.
