What is Kerberos? Kerberos is a network authentication protocol. The Internet is an insecure place. Some sites attempt to use firewalls to solve their network security problems. Kerberos was created by MIT as a solution to these network security problems. Kerberos is freely available from MIT, under copyright permissions very similar those used for the BSD operating system and the X Window System. In summary, Kerberos is a solution to your network security problems. $Id: index.html,v 1.215 2015/02/25 23:38:52 tlyu Exp $ All images and text on this page are copyright MIT.

MIT Formally Kicks Off Cybersecurity Work -- Campus Technology Security MIT Formally Kicks Off Cybersecurity Work By Dian Schaffhauser03/16/15 MIT has shared additional details on how it plans to spend a $15 million cybersecurity grant. For the technology angle, Cybersecurity@CSAIL will continue work into hardware- and software-based approaches to computer security. For the organizational side, MIT Sloan's interdisciplinary Consortium for Improving Critical Infrastructure in Cybersecurity, otherwise known as (IC)3, will focus on the human element — how organizations can make sure staff and other internal users don't create security vulnerabilities, intentionally or otherwise. "Various studies have shown that up to 80 percent of the incidents [of cybersecurity breaches] are aided or abetted by authorized users," said Stuart Madnick, a professor of IT at MIT Sloan and a professor of engineering systems, who will lead (IC)3. About the Author Dian Schaffhauser is a writer who covers technology and business for a number of publications.
About Exploit Exercises 5 Killer Tricks to Get the Most Out of Wireshark Wireshark has quite a few tricks up its sleeve, from capturing remote traffic to creating firewall rules based on captured packets. Read on for some more advanced tips if you want to use Wireshark like a pro. We’ve already covered basic usage of Wireshark, so be sure to read our original article for an introduction to this powerful network analysis tool. Network Name Resolution While capturing packets, you might be annoyed that Wireshark only displays IP addresses. Wireshark can automatically resolve these IP address to domain names, although this feature isn’t enabled by default. You can enable this setting by opening the preferences window from Edit -> Preferences, clicking the Name Resolution panel and clicking the “Enable Network Name Resolution” check box. Start Capturing Automatically You can create a special shortcut using Wirshark’s command-line arguments if you want to start capturing packets without delay. wireshark -i # -k Capturing Traffic From Remote Computers

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. The WPS PIN is an eight-digit random number. The main problem lies with how devices respond to failed WPS authentication attempts. The U.S.

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? You did what you were told to do, you logged into your router after you purchased it and plugged it in for the first time, and set a password. What does it matter what the little acronym next to the security encryption standard you chose was? WEP, WPA, and WPA2: Wi-Fi Security Through the Ages Since the late 1990s, Wi-Fi security algorithms have undergone multiple upgrades with outright depreciation of older algorithms and significant revision to newer algorithms. Wired Equivalent Privacy (WEP) Wired Equivalent Privacy (WEP) is the most widely used Wi-Fi security algorithm in the world. WEP was ratified as a Wi-Fi security standard in September of 1999.
InfoSec Handlers Diary Blog - Hashing Passwords After talking about SQL Injection, this is the second part of the mini series to help you protect yourself from simple persistent attacks as we have seen them in the last couple months. A common MO employed in these attacks is to steal passwords from a database via sql injection. Later, the attacker will try to use these passwords to break into other sites for which users may choose the same password. First of all: What is hashing? Storing a password as a hash will make it difficult to figure out the actual password a user used. A hash isn't fool proof. Probably the most important defense against rainbow tables is the idea of introducing a "salt". In order to use a "salt", the salt value and the users password are first concatenated, then the string is hashed. Another trick to harden a hash is to just apply the same algorithm multiple times. When selecting an algorithm to hash passwords, it is important to select carefully as it is difficult to change the algorithm later.
Storing Passwords - done right! Written by: Christoph Wille Translated by: Bernhard Spuida First published: 1/5/2004 Viewed 257725 times. 1766 ratings, avg. grade 4.76 In very many - not to say almost all - Web applications user data is administered, from Web forum to Web shop. These user data encompass login information of the users which contain the password besides the user name - and this in plain text. A security leak par excellence. Why is storing the user name and password in plain text a security leak? How can this security risk be eliminated? What is a Salted Hash? A hash is a numerical value of fixed length which unequivocally identifies files of arbitrary legth. The reason for this is that usually so called 'Dictionary Attacks' are run against hashed passwords - a good example being the MD5 hashed passwords of NT4. The intention behind a Salted Hash is to have this type of attack fail by attaching a random value - the so called salt - to each password and only then compute the hash over password and salt.
