How the basics of network security systems have evolved
Today's sophisticated network security technologies work together to provide a tighter net and block malicious behavior both within and at the edge of the network. Read Now
For any enterprise, getting the network security basics right is critical, and next-generation threats require a next-generation approach. The challenge for network security architects today is to ensure network security tools work with each other rather than alongside each other, and not just at the network edge, but within the network itself.
Many network security systems are difficult to implement and require a trained staff to oversee updates and maintenance. The high overhead costs associated with this oversight means many network security tools are not implemented fully in the enterprise, leaving those organizations vulnerable to emerging threats and determined hackers.
Next-generation network security tools aim to correct this by providing overlapping protection to implement a defense-in-depth strategy. Firewalls, secure Web gateways, and intrusion prevention systems thwart attacks at the network's edge, while malware sandboxes provide strategic depth, and network access control tools protect the network from within.
1The business case for network security tools
Next-generation security tools can help prevent data breaches that put the enterprise at risk from both a regulatory and customer trust perspective. A robust network security posture can also lower overhead costs and allow businesses to expand into BYOD, cloud services, IoT and other undertakings.
2Criteria to consider when buying network security products
Before making your purchasing decision, consider where your mission-critical data resides, how devices access your network, and how your network security tools will be deployed.
3Which network security products should I buy?
Network security basics call for a comprehensive examination of the wide range of network security products now available in the marketplace. But narrowing these down to the select few you will deploy in your network requires patience and a focused approach.
