You have firewalls and antivirus software. You implement security patches regularly, and even have IDS. You may think you're doing all you can to protect your network, but think again. Security dangers you're not even aware can be lurking in every corner of your network. Security expert Dave Piscitello presents the top ten practical guidelines you can put into place today to protect your network and critical data in the future.
- Adopt a risk management methodology – ou can't know what to protect and how much to spend if you don't know what assets are at risk.
- Layer your security measures – Complement firewalls with host and application security.
- Compartmentalize your network and data – Would you put a screen door on a submarine?
- Implement stronger authentication – Authentication is the enabler of all security, so firm it up!
- Implement admission and endpoint controls – Only allow devices that pass admission criteria to connect to your network.
- Improve the granularity of your access controls – Carte blanche access is a recipe for disaster.
- Develop a secure software methodology – Secure code review and testing are as important to Web applications as operating systems.
- Be proactive with security – Routinely scan networks, servers and clients.
- Develop an "attack anticipation" mentality – Prevention is better than detection.
- Ensure information integrity, privacy, availability – If you can't make your data accurate and available to authorized users only, what's the point of networking at all?
