Five Tips for Better Internal Network Security

In the early days of the Internet, a firewall and intrusion prevention system was enough to protect your network from hackers. Yet as the threat landscape evolved and the targets of these hackers changed from the large Fortune 1000 companies to small and mid-size businesses, it is no surprise that these external security solutions alone will no longer be enough to defend your network from attack.

Hackers can retrieve sensitive information from a business in many ways, largely stemming from holes in your internal network. Knowing the vulnerabilities that exist on your network as well as the devices, both trusted and not, are the first steps in securing your network from the inside-out. Yet internal security is expensive, and many businesses like yours are struggling to find the best fit to properly secure your networks at the right price and in a simple manner.

We, along with our partner, NetClarity, have compiled the top five tips for better internal network security:

Tip #1: Asset Discovery: Make sure you always have an up-to-date list of assets on your network: use agentless NAC technology to discover network assets.
  • Who’s on the network? BYOD?
  • Baseline for building the trust list
  • Activate easy-NAC blocking engine
  • Quarantine or block unknown or infected assets from gaining access to your network
Tip #2: Asset Analysis: Once you have an accurate asset inventory, analyze each asset by fingerprinting it – no agents or clients are necessary with agent-less NAC. Key information is obtained to make:
  • Network access decisions
  • Vulnerability assessments
Tip #3: Vulnerability Auditing:Make sure you are scanning your attached network devices for vulnerabilities and exposures – find and fix holes on your network quickly! Assets (or the entire network) can be audited to:
  • Make access decisions and identify network trends
  • Assess vulnerabilities
Tip #4: Malware Protection: Monitor each asset for zero-day malware and Advanced Persistent Threats (APTs). Common anti-virus software does not find “zero-day” malware! You need a solution that is:
  • Non-intrusive
  • Looking for call-back URLs
  • IT manager can then determine actions
Tip #5: Compliance Reporting: Know exactly what is going on within your network with compliance reporting and provide this information to auditors and management!
  • Audit yourself with NACwall’s built-in CVE® certified vulnerability scanning and management system.
  • Report using over a dozen different reports including Differential and Trend Analysis reports.
  • Comply with GLBA, HIPAA, Visa PCI, NERC/FERC and many other U.S. and international regulations.

Small and Medium-sized Enterprises NEED security. Follow these tips and be on your way to a secure network, from the inside-out.
