Poor Firewall Management Leaves Networks Vulnerable to Attack

By Ericka Chickowski on 2011-12-08



Managing changes in firewall rules is a necessary evil for security professionals. Many, however, don’t believe they have the time or resources to undertake the complicated and time-consuming steps necessary to make sure their corporate firewalls are up-to-date and secure. In reality, security professionals sometimes resort to cheating, shortcutting, or the old bubble-gum and duct-tape approach -- wasting both time and money in the long run for a few dollars and minutes saved now. Most audit cheaters cited lack of time, many also said that they felt the audit’s requirements were irrelevant to the business or they feared that the network security team would seem incompetent. And while the overworked network security staff struggles to keep up, attackers are poised to find a way in through any cracks. A recent survey of network security professionals conducted by Tufin Technologies shows just how big those cracks are, and the areas where security professionals are struggling.
