Network Access Control (NAC) ensures only authorized devices and users reach your network. It enforces policy, blocks unauthorized access, and reduces risk from malware and data breaches. Here’s how to configure it in your environment. 1. Define Your NAC Objectives Security: Protect sensitive systems and data. Compliance: Meet regulatory requirements (e.g., GDPR, HIPAA). Visibility: See […]
Educational institutions handle sensitive data on shared networks with a diverse user base — students, faculty, administrators, and guests. Here’s how to secure that infrastructure. 1. Network Security Segment the network. Use VLANs to separate student, faculty, administrative, and guest traffic. A breach in one segment shouldn’t compromise the others. Deploy next-generation firewalls and IDS/IPS […]
Certificates keep your infrastructure talking securely. When they expire or get misconfigured, things break — often visibly, sometimes silently. Here is how to manage the full lifecycle without it becoming a fire drill. 1. Know the stages Every certificate moves through the same states: Request — Generate a CSR and submit it to a CA. […]
1. Conduct a Risk Assessment Audit current infrastructure: identify vulnerabilities in servers, networks, storage, backups, and endpoints. Classify data by sensitivity and criticality — client data, legal documents, intellectual property. Evaluate threats: phishing, ransomware, insider threats, data breaches. 2. Implement Strong Network Security Deploy firewalls that inspect and filter traffic at the application layer. Require […]
Enterprise wireless security comes down to encryption, authentication, segmentation, and continuous verification. Below are the hardening steps that actually move the needle. 1. Require WPA3-Enterprise Deploy WPA3-Enterprise (SAE or 192-bit mode where hardware supports it). Disable WEP, WPA-TKIP, and WPA2-Personal. If legacy clients force WPA2-Enterprise, enforce AES-CCMP only and plan migration. 2. Enforce 802.1X with […]
