Takeaway: Internet Explorer 7 is designed to make browsing safer. Here's a quick rundown of some of the new security features, including Active X opt-in, the Phishing Filter, cross-domain security, enhanced privacy protection, and an international character alert.
The code, which was posted on the Internet early Sunday morning, could be used to disable the Windows Firewall on a fully patched Windows XP PC that was running Windows' Internet Connection Service (ICS). This service allows Windows users to essentially turn their PC into a router and share their Internet connection with other computers on the local area network (LAN.) It is typically used by home and small-business users.
This is a cool little trick I’ve picked up in my travels and decided to share it with you fine and ethical individuals =). Log in and go to your DOS command prompt and enter these commands exactly:
copy logon.scr temphack\logon.scr
copy cmd.exe temphack\cmd.exe
rename cmd.exe logon.scr
A vital tool to use when troubleshooting computer networking problems and monitoring computer networks is a packet sniffer. That being said, one of the best methods to use when troubleshooting connection problems or monitoring suspicious network activity in a Cisco Systems PIX firewall is by using the capture command. Many times Cisco TAC will request captures from a PIX in PCAP format for open problem tickets associated with unusual problems or activity associated with the PIX and the network.
Since our talks at Black Hat Vegas and DEFCON, Jon Ellch and I have been peppered with questions regarding how to find vulnerabilities in wireless device drivers and the specific techniques that were employed. Rather than answer these questions one at a time, an article seemed a better course of action. In this first article, we will discuss how to build an auditing environment, how to construct fuzzing tools and, finally, how to interpret the results.
IPsec is a suite of protocols for securing network connections, but the details and many variations quickly become overwhelming. This is particularly the case when trying to interoperate between disparate systems, causing more than one engineer to just mindlessly turn the knobs when attempting to bring up a new connection.
Firewalls are one of the fastest growing technical tools in the field of information security. However, a firewall is only as secure as the operating system it resides upon. This article will take a step by step look at how you can best armor your Solaris box, both Sparc and x86. These steps can apply to any situation, however I will be using Check Point FireWall-1 on Solaris 2.6 as an example. At the end of this article is a script that you can download that will automate most of the armoring process, to include implementing TCP Wrappers.
This white paper shows how to meet the challenge of low fiscal impact by using open source tools and re-purposing equipment in-hand. The challenge of low service impact was met through three layers of analysis before cutover. The methods used to develop this analysis are structured for re-use in other firewall projects and presented for use by others with similar challenges.
This tutorial is a comprehensive guide to the features provided by the Nmap Port Scanner. It is meant as an introduction for new users, a reference on new and existing features for experienced users, and an FAQ list. It is not intended as a replacement for the Nmap Manual Page, but more as a supplement to it.
There are times when you have to restart the fwd deamon. You might have to restart this in case the firewall starts logging locally, or you encounter a runaway process where the firewall experiences high CPU, or other instances where the firewall might start dropping packets for not so well known reasons.You can use this command to restart the Firewall deamon, fwd process using the watchdog services.
Check Point Software Technologies plans to acquire intrusion prevention company Sourcefire in a $225 million deal, as it seeks to expand beyond its core firewall and virtual private network businesses.
A flaw in Windows Firewall may prevent users from seeing all the open network ports on a Windows XP or Windows Server 2003 computer.
The flaw manifests itself in the way the security application handles some entries in the Windows Registry, Microsoft said in a security advisory published Wednesday. The Windows Registry stores PC settings and is a core part of the operating system.
If you have given your trusted employees and key contractors remote access to your network via a client virtual private network (VPN), congratulations! By now, you have seen the productivity and cost benefits from allowing collaboration that surmounts geographical separation.
Cross-site scripting, often abbreviated XSS, is a class of Web security issues. A recent research report stated that XSS is now the top security risk.
