Five free network analyzers worth any IT admin's time If you work on a network, you then know the value of information. Solid information leads to a strong and worry-free network (or at least as worry-free as you can manage). In order to gather that information, you need the right tools. The tools I speak of are network analyzers.
HTG Explains: The Difference Between WEP, WPA, and WPA2 Wireless Encryption (and Why It Matters) Even if you know you need to secure your Wi-Fi network (and have already done so), you probably find all the encryption acronyms a little bit puzzling. Read on as we highlight the differences between encryption standards like WEP, WPA, and WPA2–and why it matters which acronym you slap on your home Wi-Fi network. What Does It Matter? 4 Keys To A Data Security Strategy Organizations must prepare for the inevitable security breach and focus on protecting sensitive corporate data. Here are some ideas to build on. If you’re an IT pro, protecting your company’s security may have recently become part of your job description. This probably didn’t come as a surprise -- more than 40% of companies suffered a breach last year, according to the Ponemon Institute. Maintaining a secure environment is no longer a question of locking down the perimeter or eliminating the chance of an attack.
Wi-Fi Protected Setup Flaws Make Wireless Network Brute-force Attacks Feasible Design flaws in the Wi-Fi Protected Setup (WPS) wireless standard can make it easier for attackers to obtain access codes for secured wireless networks by brute force. The vulnerabilities identified by security researcher Stefan Viehbock affect a large number of WPS-enabled routers and wireless access points. The WPS standard was created in 2007 by the Wi-Fi Alliance in order to provide non-technical users with a simple method of setting up wireless networks. The standard supports several Wi-Fi authentication methods including one that requires pushing a physical button on the router and one that uses a predefined PIN number printed on a sticker by the device manufacturer. The PIN-based method is mandatory for WPS-certified devices, which support it by default.
Understanding and selecting authentication methods If you are serious about computer/network security, then you must have a solid understanding of authentication methods. Debra Littlejohn Shinder takes a moment to lay out the role authentication plays in a security plan. Computer/network security hinges on two very simple goals:Keeping unauthorized persons from gaining access to resourcesEnsuring that authorized persons can access the resources they needThere are a number of components involved in accomplishing these objectives.

IPv6: The security risks to business Predictions about when the world will end are about as consistent as the predictions about when IPv4 internet addresses will finally run out, but some IT security professionals say that is really the least of our worries. A much bigger concern, they say, should be the security holes that will open up in many business organisations as the world moves over to internet protocol version six (IPv6). This is an important aspect of the changeover that has been lost in all the hype around how IPv4 is about to run out of IP addresses assigned to each internet-connected device because of the explosion of internet users, devices and web services. IPv6 will solve this problem because it provides over four billion times more addresses than IPv4, but in solving that problem, it could expose businesses to cyber attacks as hackers use IPv6 to bypass security controls and filters designed and configured for IPv4 traffic. IPv6 attacks likely to increase with adoption Security advantages of IPv6
Radia Perlman On SDN, IPv6 & Security The networking pioneer touched on current hot topics in a keynote speech at the 2015 USENIX Annual Technical Conference. Radia Perlman is a legend in the networking industry, having invented the Spanning Tree Protocol (STP) and then improved on STP with TRILL (Transparent Interconnection of Lots of Links). With a PhD in computer science from MIT, she holds more than 100 patents and is currently a fellow at EMC.
Working with Open Shortest Path First (OSPF) Routing Protocol Because Open Shortest Path First (OSPF) is an open standard protocol, many people have contributed to its design and thousands upon thousands of people have reviewed it. In this section,some functional components of this interior gateway protocol (IGP) and its use in your networks will be highlighted. Because every IGP behaves slightly differently from other IGPs, you should be familiar with a few OSPF terms that are used with the protocol before jumping into the configuration commands. This section attempts to clarify the major terms and concepts you should be familiar with.
How Hackers Protect Themselves From Getting Hacked When Adrian Lamo goes online, he leaves nothing to chance. To log in to personal accounts, he uses a digital password generator -- a plastic key chain-like device that displays a new string of digits every 60 seconds. He adds an extra layer of security to some accounts by entering a special code that he receives via text message. And he uses browser extensions to avoid downloading malware by accidentally visiting dangerous Web sites. Some techniques “may seem like a ‘Mission Impossible’ level of security to the average user," Lamo said. Dhcp Explorer - Discover DHCP servers on your LAN Dynamic Host Configuration Protocol (DHCP) is a client-server networking protocol and uses the same two IANA assigned ports for BOOTP: 67/udp for the server side, and 68/udp for the client side. A DHCP server provides configuration parameters specific to the DHCP client host requesting, generally, information required by the client host to participate on an IP network. DHCP also provides a mechanism for allocation of IP addresses to client hosts. DHCP server is a useful tool that automates the assignment of IP addresses to hundreds of workstations in your network. The server maintains a pool of IP addresses that you use to create scopes.
Cybercrime in the DeepWeb Earlier, we published a blog post talking about the recent shut down of the Silk Road marketplace. There, we promised to release a new white paper looking at cybercrime activity on the Deep Web in more detail. This paper can now be found on our site here. While the Deep Web has often been uniquely associated with The Onion Router (TOR), in this paper we introduce several other networks that guarantee anonymous and untraceable access — the most renowned darknets (i.e., TOR, I2P, and Freenet) and alternative top-level domains (TLDs), also called “rogue TLDs.” We analyzed how malicious actors use these networks to exchange goods and examined the marketplaces available in the Deep Web, along with the goods offered.
80+ Best Free Hacking Tutorials Learning to become hacker is not as easy as learning to become a software developer. I realized this when I started looking for learning resources for simple hacking people do. Even to start doing the simplest hack on own, a hacker requires to have in depth knowledge of multiple topics. Some people recommend minimum knowledge of few programming languages like C, Python, HTML with Unix operating system concepts and networking knowledge is required to start learning hacking techniques. Though knowing a lot of things is required, it is not really enough for you to be a competent and successful hacker.
syswow64 blog: Bitlocker What is Bitlocker? Bitlocker Drive Encryption allows you to encrypt all data stored on the Windows operating system volume and configured data volumes, and by using a Trusted Platform Module (TPM), it can also help ensure the integrity of early startup components. Bitlocker was updated with the release of Windows 7 and Windows Server 2008 R2.
