In our previous post, we explored the foundational elements of building a strong and scalable network. Now, in part two of our series, we turn our focus to securing that network and preparing for the future.
At KayPrism, we understand that security is not just an add-on but an integral part of network design. In this blog, we’ll discuss about the integration of security from ground up, identify common threats, and explore proactive measures and future trends like SD-WAN and Zero Trust.
Security from the Ground Up
Security should never be an afterthought. In fact, the most resilient networks are those where security is baked into the design from day one, integrating security protocols during the network design phase. This includes defining access controls, authentication methods, and data handling procedures early. For example, implementing role-based access control (RBAC) ensures that employees only have access to the resources they need for their job roles.
Common Threats to Network Infrastructure
- Malware & Ransomware: These can cripple operations and compromise sensitive data. Regularly updating antivirus software and educating employees about phishing attacks can mitigate these risks.
- Phishing Attacks: Target employees to gain unauthorised access. Implementing multi-factor authentication (MFA) can add an extra later of security.
- DDoS Attacks: Overwhelm your network, causing service outages. Using DDoS protection services can help absorb and mitigate these attacks.
- Insider Threats: Often overlooked, but potentially devastating. Monitoring user activity and implementing strict access controls can help detect and prevent insider threats.
Proactive Security Measures
- Firewalls & IDS/IPS: First line of defense against unauthorised access. Firewalls control incoming and outgoing traffic, while Intrusion Detection and Prevention Systems (IDS/IPS) monitor and respond to suspicious activites.
- Encryption: Protects data in transit and at rest. Using strong encryption protocols ensures that even if data is intercepted, it remains unreadable to unauthorised parties.
- Continuous Monitoring: Use Security Information and Event Management (SIEM) tools to detect and respond to anomalies in real time. Continuous monitoring helps identify potential threats before they can cause damage.
The Synergy Between Network Building and Security
Network performance and security are not separate goals—they are interdependent. A fast network that isn’t secure is a liability. A secure network that isn’t efficient can hinder productivity.
Why Integration Matters
- Unified Management: Centralised control simplifies both performance tunning and threat response. This ensures that security policies are consistently enforced across the network.
- Reduced Risk: Integrated systems are harder to exploit and easier to monitor. This reduces the likelihood of successful attacks and minimises the impact of any breaches.
- Business Continuity: A secure, resilient network ensures minimal disruption during incidents. This helps maintain operations and protect the company’s reputation.
Future Trends: What’s Next for Networking and Security?
As technology evolves, so must your network strategy. Here are some key trends to watch:
Software-Defined Networking (SDN)
What is it: SDN separates the control and data planes, allowing centralised, programmable network management.
Benefits: Enables faster deployment, better traffic control, and improved security enforcement.
SD-WAN (Software-Defined Wide Area Network)
What is it: A specific application of SDN that optimises WAN performance by dynamically routing traffic across multiple connections.
Benefits: Lower costs by reducing reliance on expensive MPLS, improved performance for cloud applications, and built-in security features like encryption and firewalls.
Zero Trust Architecture
What is it: Never trust, always verify.
Benefits: Limits lateral movement within networks and reduces breach impacts.
AI-Driven Network Management
What is it: Predictive maintenance, anomaly detection, automated threat response.
Benefits: Reduces human error and improves uptime.
Edge Computing & 5G
What is it: Processing data closer to the source, reducing latency and bandwidth usage.
Benefits: Requires decentralised security modeals and robuts endpoint protection.
Final Thoughts
Security is not a destination, it is a continuous journey. By integrating security from the start and embracing future-ready technologies, businesses can build networks that are not only resilient but also agile and scalable.
