There are two denial of service (DoS) conditions in the Tiny Personal support Firewall 3.0 window. The first concerns a vulnerability affecting late installation and use of certain activity recorder tabs. When an attacker uses SYN, UDP, Internet Control Message Protocol (ICMP), and TCP Full Connect to allow you to port scan a host while a vulnerable user scans the firewall log of the Personal Firewall Agent Module from the host, it causes a system crash. which consumed 75% of system resources. The second DoS condition is similar to the first, but occurs with our own high security settings, when an attacker uses a fake source that accesses the IP address of a specific firewall.
Software vendor Tiny has been notified but is not yet offering a fix for this vulnerability. ”

The first quantitative evaluation of the quality of enterprise firewall configuration evaluation was carried out in 2004 based on the Check Point Firewall 1 rule sets. In general, one should consider the fact that corporate firewalls too often use poorly written rule sets. This article goes back to the first poll. The current human study is not only larger, but also includes setups from two major vendors. It also introduces strategic complexity. The results of the study confirm the main findings of the 2004 study: firewalls are (still) poorly configured, and management system complexity is (still) positively related to the number of configuration errors found. However, unlike the 2004 specific study, the current study does not indicate that later versions of the software contain fewer bugs.

Security educators generally agree that corporate firewalls
very often require poorly written brainstorming. This text is based on a 2005 survey
of headquarters firewalls, in which most of them assessed the magnitude of the problem. The current study is not only
more extensive, but includes installations involving two main
suppliers. Another new “demographic measure” is also introduced, which
corresponds to both types of “measures”. The results of the study confirm
the most important human observation of 2004: “Firewalls are common, (still) misconfigured, and theory complexity
(still) is positively related to the number of configuration errors detected.
However, unlike the 2004 study, the groundbreaking study does not suggest that this may happen later.
There are fewer problems in software releases.
