With security constantly in the news lately, you can’t help but feel ill at ease and vulnerable — vulnerable to teams of hackers whose only motivations are to expose and attack their victims. Perhaps you think you’ve done due diligence by keeping your patches updated, installing security fixes, and maintaining a corporate firewall.
Those methods are effective about 50 percent of the time. For the other 50 percent, you need to do more. You need penetration testing, security audits, intrusion prevention and intrusion detection, and you need to plug security holes that only hackers know about by using the tools they use to compromise your systems.
Security is expensive no matter how you slice it but it doesn’t have to be a death knell for your business. This list of 10, in no particular order, security-enhanced Linux distributions can give you peace of mind by beating hackers on their turf.
