CISA legislation would lift liability for businesses sharing cyber threat information

A bill that encourages businesses to share threat intelligence with each other and the government is closer to becoming a law than it has been for years now that it offers businesses near immunity from liability if the data they share is stolen and causes harm, but such sharing is still fraught with problems. Nathan Taylor The proposed Cybersecurity Information Sharing Act (CISA) proposal doesn’t force anyone to participate in sharing, but it creates incentives for businesses to do so willingly, says Nathan Taylor, a partner in the law firm Morrison & Foerster, who is following the bill as it wends its way through Congress.To read this article in full or to leave a comment, please click here

Techies back Democrats in Presidential race

It will be many months before presidential candidates face their respective conventions, but for the time being the Democrats are winning the wallets of technology workers. Finance reform bars corporations from directly funding campaigns, but that doesn’t stop individuals from backing candidates of their choice. And according to Network World’s analysis of candidates’ most recent filings to the Federal Elections Commission, those technology workers donated far more to Democratic presidential candidates than did their Republican counterparts since the inception of each candidate’s campaign. The two frontrunning Democrats outpaced the three Republicans examined: $393,444 to $36,588. Network World reviewed the campaign finance reports of the two candidates from each party who are currently leading the polls and also included former HP chief Carly Fiorina.To read this article in full or to leave a comment, please click here

Survey: Vendor NETCONF and REST API Support

Time for another fill-in-the-blanks survey: how many vendors support NETCONF and/or REST API in their data center switches, routers, firewalls and load balancers?

Please help me complete the tables by writing a comment – and do keep in mind that it only counts if it’s documented in a public configuration guide on vendor’s web site.

Also, I’m not aware of any vendor using standard NETMOD YANG models. If someone does, please let me know.

Network Simulation – Cisco VIRL Increases Node Count

Great news everyone. Some of you might have seen that I created a petition to increase the node limit in VIRL. I know there have been discussions within Cisco about the node limit and surely our petition wasn’t the single thing that convinced the VIRL team but I know that they have seen it and I’m proud that we were able to make a difference!

On November 1st the node limit will be increased to 20 nodes for free! That’s right, you get 5 extra nodes for free. There will also be a license upgrade available that gets you to 30 nodes. I’m not sure of the pricing yet for the 30 node limit so I will get back when I get more information on that.

When the community comes together, great things happen! This post on Cisco VIRL will get updated as I get more information. Cisco VIRL will be a much more useful tool now to simulate the CCIE lab and large customer topologies. I tip my hat to the Cisco VIRL team for listening to the community.

Windows users often forget to patch their Apple programs

A survey of applications installed on Windows computers found that a lot of users don't run up-to-date versions of Apple programs. Apple's multimedia program, QuickTime, and its iTunes software were ranked as some of the most "exposed" programs based on risk by Secunia Research, which is now part of Flexera Software. Among U.S. users, some 61 percent of computers detected running QuickTime did not have the latest version. With iTunes, 47 percent of the installations were outdated versions. It's not Apple's fault. Although many software companies alert users to new versions of applications, it's largely up to users to install them.To read this article in full or to leave a comment, please click here

VRRP on Linux Using Keepalived – The Basics

I’ve recently been working on an implementation of VRRP on Linux using Keepalived to provide IP redundancy for some HA Proxy load balancers. I’ve been pleasantly surprised by how simple and fast it is and thought I’d share the details now I understand why it’s the default choice for many. Keepalived has been around for 15 […]

Strengthen your network security with Passive DNS

Over the past few years, we’ve witnessed increasing attacks against DNS infrastructure: DDoS attacks against authoritative name servers, name servers used as amplifiers in DDoS attacks, compromised registrar accounts used to modify delegation information, cache poisoning attacks, and abuse of name servers by malware. Thankfully, we’ve also seen the concurrent development of powerful new mechanisms for combating those threats, including the DNS Security Extensions, response policy zones, and response rate limiting.Perhaps the most promising means of enhancing DNS security, and the security of the Internet generally, has yet to be fully exploited. That’s Passive DNS data.To read this article in full or to leave a comment, please click here

Microsoft’s advice: Hang up on tech support scammers

Microsoft's best advice to combat tech support scams? Hang up the phone."You get a call from someone that's unsolicited, talking about technical support, hang up," said David Finn, the executive director of Microsoft's Digital Crime Unit, during a hearing held by the U.S. Senate last week. "That's the first thing. That is not a legitimate effort to sell something to you."Finn was one of several people who testified last Wednesday before the Senate's Special Committee on Aging, which held a hearing on technical support scams, which disproportionately target the elderly.Such scams, Finn said during his prepared testimony, are the "single largest consumer fraud perpetrated in America today." They victimize an estimated 3.3 million people and rake in $1.5 billion annually. "This translates to a victim nearly every 10 seconds, with an average loss of $454 per consumer," Finn said.To read this article in full or to leave a comment, please click here

IDG Contributor Network: How hackers compromised chipped credit cards, and how the authorities discovered it

Chipped cards have been hacked in the past, despite the security rhetoric from banks and merchants.Until recently, it was done through a Man-in-the-Middle attack.'Man-in-the-Middle' is where an attacker changes the communication between parties who think they're talking with each other directly.Security measures are now in place to stop this kind of chip scam, but it was not until scientists studied the forensics that the police could even figure it out.Second chip It turns out that the fraud worked through a second chip embedded in the card, installed there by the crook.The glued-on dummy chip answered affirmatively when polled. It let a transaction go through when the terminal asked the card's original chip if the entered PIN was correct, Catalin Cimpanu explained in a Softpedia article.To read this article in full or to leave a comment, please click here

South Korean manufacturing industry targeted with new backdoor program

South Korean organizations are being targeted in attacks with a new stealthy backdoor program that gives attackers full access to infected computers.The malware has been dubbed Duuzer and while it's not exclusively used against targets in South Korea, it does seem that the hacker group behind it have a preference for that country's manufacturing industry, according to security firm Symantec.Duuzer was designed to work on both 32-bit and 64-bit Windows versions and opens a back door through which attackers can gather system information; create, list and kill processes; access, modify and delete files; execute commands and more."It’s clearly the work of skilled attackers looking to obtain valuable information," researchers from Symantec's security response team said in a blog post.To read this article in full or to leave a comment, please click here
