You're in charge of network security. How do you juggle continuous monitoring and high-level standards?

- Set Policies on monitoring framework viz- Develop high-level standards for technologies and processes (e.g., encryption protocols, firewall configurations) that align with industry best practices (like NIST, SANS25, CIS, ISO 27001). - Use continuous monitoring tools such as security information and event management (SIEM) systems, SOAR and intrusion detection/prevention systems (IDS/IPS) to monitor network traffic and detect anomalies in real time - Continuous Improvement: Establish a feedback mechanism to continuously evaluate the effectiveness of security measures and make necessary adjustments.

In my view, managing network security is like keeping a machine running smoothly. Continuous monitoring is like regular check-ups, while maintaining high standards ensures efficiency. I’d use automated tools like IDS/IPS and SIEM for daily checks, freeing up time to focus on broader improvements like updating security strategies and training staff. Regular reviews of policies, system performance and threats will help keep the network secure without compromising quality or performance.

Managing network security effectively requires a delicate balance between continuous monitoring and adhering to high-level standards. the strategy is 1. implementing a robust monitoring system like using Automated tools, Log management and Network traffic analysis 2. Establish Clear Security Policies and Standards like Ensure adherence to relevant regulations (e.g., GDPR, HIPAA) and integrate these requirements into your security posture. 3. Continuous improvement like regular audit and Keep all systems, software, and hardware up to date with the latest security patches and updates.

1. Monitoring and Detection : Implement SIEM and SOAR solutions, tools and technologies such as IDS, IPS, Firewalls at network endpoints or to find Indicators of Compromise to avoid unauthorized access to the network and proactive monitoring of any escalated alerts or incidents. Implement network segmentation to isolate critical assets and limit the impact of potential breaches. 2. Implement best security policies and ensure to follow standard frameworks required by the law, (e.g., NIST, ISO/IEC 27001). Conduct regular audits to ensure policies are followed and adjust them based on evolving threats. 3. Develop and maintain an incident response plan with clearly defined roles and procedures for handling security incidents.

Number one is read as much as you can. Don't silo yourself into the things that you know. Look for the things that you don't know. Another thing is to automate as much as you can, but don't be afraid to get your hands dirty into your SIEM. A third thing would be to play the other side. Think of how an attacker thinks. What are your weaknesses that can be exploited? This method will improve your level of vigilance immensely. Lastly, don't forget that a cyber security professional is an evangelist. Preach to people what they can do to protect themselves, but also what they can do for their organization.

Although policy is important, you may already have a policy in place. If so, your time could be best spent updating policy requirements to account for software defined networks and making policies more flexible to accommodate cloud based computing. In a cloud first world, with virtual address spaces, compute or storage elasticity and regional data centers, you may find that the policy prevents the organization from considering risk appropriately.

Crafting robust security policies is essential for aligning continuous monitoring with high-level standards. Develop policies that define security objectives, acceptable use, and monitoring practices. Ensure these policies incorporate best practices and compliance requirements. Clearly outline roles and responsibilities to enforce policies effectively. Regularly review and update policies to adapt to evolving threats and technological advances. By creating well-defined policies, we set a framework that supports ongoing monitoring while maintaining rigorous security standards.

Just like in *"The Hunt for Red October,"* where every move was a calculated strategy, crafting security policies requires precision and foresight. After assessing risks, the next step is to develop policies that dictate how to protect your network and respond to incidents. These policies must align with standards like ISO/IEC 27001, ensuring your organization navigates safely through potential threats. Like Captain Ramius following protocols to achieve his mission, your policies should be clear, enforceable, and regularly updated to reflect the latest security practices. In network security, policies are your navigational charts. How do you ensure yours are as strategic as those in "The Hunt for Red October".

And remember that tools require privileges to operate. Before purchasing tools, look at the provenance of the software and the integrity of the maintenance for that tool. If you use Open Source, you will be responsible for the update and management process. If you buy from a vendor, look at the capability of the vendor to maintain software better than you would. Can they act responsibly with the keys to your kingdom?

When selecting a system or tool, make sure you understand what your needs are and then follow a procurement process that allows for testing, reference checks, asking colleagues and friends about their experience or search in the forums. Also important to understand the level of depth and commitment the tool would require. Avoid locking yourself and your company in a multi-year agreement for a tool that will be left under-utilized or that you don't have an associate that can manage it. Some tools or systems can be "full-time jobs".

In network security, selecting the right tools is as crucial as when John McClane teamed up with hacker Matt Farrell in *"Live Free or Die Hard."* Just as they used real-time responses and advanced technology to stop a cyber-terrorist, your network needs IDS and IPS tools to detect, prevent, and respond to threats instantly. The film shows how quick thinking and the right resources make all the difference—much like how scalable, integrated security systems are essential to staying ahead of cybercriminals. Are your security tools as sharp and adaptive as those that helped McClane and Farrell save the day?

Effective training programs are vital for maintaining a balance between continuous monitoring and high-level standards. We need to develop training modules that cover security best practices, monitoring tools, and incident response procedures. We need to see that all relevant staff are trained on how to use monitoring tools effectively and understand their roles in maintaining security. We must regularly update training programs to address new threats and technological changes. By investing in comprehensive training, we will empower our team to manage monitoring tasks while adhering to security standards.

Implementing comprehensive training programs for your staff is crucial to building a strong security culture. When employees understand the 'why' behind security policies, they transform into a human firewall, actively safeguarding your organization against threats. Regular, real-world scenario-based training ensures they can recognize and respond to potential risks, enhancing continuous monitoring with human vigilance. Leadership must set the tone, making security awareness a priority at all levels. How does your organization keep security top of mind for everyone?

Any incident response plan must have interfaces to the incident response processes of machines and services hosted on the network. The plan must enable rapid response when a partner team experiences an outage. Although the outage and security responses may be handled by different groups, they must be able to interoperate and support diagnostics across those surfaces.

- Real-Time Alerts: Assess the capability of the monitoring systems to provide real-time alerts on suspicious activities or potential security incidents. - Log Management: Ensure that logs from various sources are collected, stored, and analyzed. Regular review and correlation of logs are essential for identifying patterns and potential threats. - Performance Metrics: Evaluate metrics such as the frequency of false positives/negatives, the time taken to detect and respond to incidents, and the effectiveness of threat intelligence feeds. - Incident Response: Review how well the monitoring integrates with the incident response plan. Effective monitoring should facilitate a rapid response to detected threats.

Regular compliance checks are crucial for maintaining high standards while managing continuous monitoring. We need to ensure that our monitoring practices align with relevant regulations and industry standards viz GDPR, DPDPA etc. We have to conduct periodic audits to verify compliance and identify any gaps or areas for improvement. We must add Right to Audit clause with Third Party Vendors while contract is signed. We must address any non-compliance issues promptly and adjust monitoring strategies as needed. By integrating compliance checks into our monitoring routine, we ensure that our security practices meet legal and regulatory requirements, supporting a robust and reliable security posture.

Verify that all employees that you work with whether Client or associate when responding to a ticket, look for the reason the issue came up. CALMLY explain to the employee that it's what HACKERS are looking to do and involve your associates to do the same. In the case of where I worked, make sure that they are not accessing their personal email or sending company email from their private account. In addition, do not allow clients to install their own software or use a removable drive from any machine they use. We had a very bad case of over anxious Teacher that would want to put software on her machine without corporate approval.
