ISPs: No New Cybersecurity Regulations Needed

IDG News Service (Washington, D.C., Bureau) — The U.S. Congress should resist any temptations to pass new cybersecurity rules affecting broadband and mobile service providers, a group of Internet service providers told lawmakers Wednesday.

Instead, Congress could remove some legal barriers for ISPs to share cyberthreat information with each other and for the government to share information with private companies, officials with five broadband and mobile network operators said during a hearing before the House of Representatives Energy and Commerce Committee's communications subcommittee.

Introducing DNSCrypt (Preview Release),by OpenDNS


"DNSCrypt and DNSSEC are complementary.  DNSSEC does a number of things.  First, it provides authentication. (Is the DNS record I'm getting a response for coming from the owner of the domain name I'm asking about or has it been tampered with?)  Second, DNSSEC provides a chain of trust to help establish confidence that the answers you're getting are verifiable.  But unfortunately, DNSSEC doesn't actually provide encryption for DNS records, even those signed by DNSSEC.  Even if everyone in the world used DNSSEC, the need to encrypt all DNS traffic would not go away. Moreover, DNSSEC today represents a near-zero percentage of overall domain names and an increasingly smaller percentage of DNS records each day as the Internet grows.  
That said, DNSSEC and DNSCrypt can work perfectly together.  They aren't conflicting in any way.  Think of DNSCrypt as a wrapper around all DNS traffic and DNSSEC as a way of signing and providing validation for a subset of those records.  There are benefits to DNSSEC that DNSCrypt isn't trying to address. In fact, we hope DNSSEC adoption grows so that people can have more confidence in the entire DNS infrastructure, not just the link between our customers and OpenDNS."

DNSSEC Update from ICANN 42 in Dakar

"Perhaps the most encouraging update came from CZ.NIC, the manager of Czech country-code top-level domain .cz, which has been aggressively promoting DNSSEC since 2009. According to CZ.NIC's Ondrej Filip, 17% of domains in the .cz zone are now signed. That's 145,000 domains, making .cz probably the most DNSSEC-saturated zone in both relative and absolute numbers."

The Economist: Accessories after the fact


That risks damaging the internet’s vital internal addressing system, which lets people use words instead of numbers to access websites. It also clashes with DNSSEC (don’t ask), a protocol that America has long championed to increase internet security. Messing with DNSSEC could create loopholes for hackers by allowing rogue websites to pose as legitimate ones. Savvy users (who do the most downloading) will be able to bypass these filters anyway. And the bill’s vague wording leaves open the possibility that American ISPs might have to institute more intrusive forms of filtering, with the costs, performance problems and privacy issues that would inevitably entail.

P2P DNS – Taking ownership of the internet

"DNS is one of those core technologies on which the internet runs. For most end users, DNS is pretty much invisible until they want to register their first domain for their own websites. At that point, the concept of a domain registrar suddenly pops into view."

Finland to launch improved Fi-domain name service

"Finland's telecom regulator Ficora announced that an upgraded fi-domain name service domain.fi will be launched soon. As a result of the launch process, applying for new fi-domain names or making changes to existing ones will not be possible from 17 September at 8:00hrs until 19 September at 10:00hrs.

The improved fi-domain name service offers users a more user-friendly way of applying for fi-domain names as well as for renewing, terminating and paying for them. At the same time, the system takes into consideration the modern requirements for electronic services better than before. The renewed service introduces the so-called DNSSec support to improve the information security of fi-domain names. The service also contains full IPv6 support, which is critical since it is believed that IPv6 connections will grow strongly in the future as available IPv4 addresses can no longer be assigned.

The improvements in the service contain added information on domain names for different user groups, such as companies, organisations and private persons. The service provides answers to such questions as who is entitled to apply for a domain name, to whom are fi-domain names granted, what can be registered as a domain name, what are domain names used for and the ways in which one can apply for a domain name.

The service has a specific section for service providers who can be authorised to apply for a domain name and assists domain name applicants in matters concerning the name server, server status and e-mail servers."

PROTECT IP threatens the future of DNS security

"PROTECT IP is the name of a bill which is working its way through the US Senate with a version also expected to be introduced in the House of Representatives next month. It would require the Attorney General's office to compile of list of domain names which DNS operators (in the US) will be required to block. According to some critics, it threatens to undo more than a decade of Internet security development in a single stroke."- AfterDawn

Getting started with a DNSSEC implementation

"Can you clarify what fixes are being implemented to the DNS system (via DNSSEC) to make it more secure? Do enterprises need to take any action in turn or will these DNS security improvements be transparent?

Attackers sometimes attempt to manipulate DNS records through cache-poisoning attacks that insert malicious false DNS records into a server. Attackers hope these records will be distributed to client machines, which will then unknowingly guide users to malicious webpages.

Until recently, there was little that could be done on the client side to defend against this type of attack.  But the release of the DNS Security Extensions (DNSSEC) changes that, allowing for the application of digital signature technology to DNS records, and providing the end user with assurance that the record is authentic.
The idea to secure DNS has been around for over a decade, but it took time to work out the details, and adoption has been quite slow.  Over the past year, the idea picked up some steam, especially after the publicity surrounding the DNS vulnerabilities that Dan Kaminsky announced at 2010 Black Hat Briefings conference.  Major network and hosting providers such as Comcast and GoDaddy have joined the federal government in deploying DNSSEC.

If you want to get started with a DNSSEC implementation"

DNSSEC signature can crash Bind name servers



"Where a Bind name server is set up as a caching resolver, it is vulnerable to DoS attacks which could cause it to crash. ISC describes the issue in its advisory Large RRSIG RRsets and Negative Caching can crash named and categorises the problem, which can be triggered remotely, as 'high' severity.

The DNSSEC extension plays a key role in the latest security problem to hit the widely used name server. It appears that the internal memory manager can become confused when it has to cache signed entries for non-existent domains. ISC's Larissa Shapiro has confirmed to The H's associates at heise Security that servers which do not themselves offer DNSSEC functionality are also vulnerable.

According to ISC, to exploit the bug an attacker must be running a DNSSEC-signed authority server for a domain. He would then be able to induce DNS lookups for non-existent names on that domain (for example by sending out spam), which would trigger the bug on the vulnerable name server. Versions 9.4-ESV-R3, 9.6-ESV-R2, 9.6.3, 9.7.1, 9.8.0 and earlier are all affected. ISC has released updates which should fix the problem."

BIND Update Patches Security Flaw

The Internet Systems Consortium (ISC) recently released Update 9.8.0-P1 for its BIND DNS server, which closes a potential denial of service vulnerability.
"Signed server replies (RRSIG) can cause a BIND server to crash under certain circumstances," The H Security reports. "ISC says that the vulnerability only occurs, however, if the vulnerable server supports response policy zones (RPZs)."
"ISC says the DoS has not yet been used for actual attacks, but the firm is keeping an eye on a number of DNSSEC validators that have sent answers to the BIND server which unintentionally caused crashes," the article states.
Go to "Update for BIND server patches DoS hole" to read the details.

.CO Registry Deploys DNSSEC

"Joins a select group of Registry operators leading the charge in the implementation of a suite of new security features that will help create a more secure internet.

.CO Internet S.A.S., the Registry operator for the .CO domain, yesterday announced that it has completed deployment of Domain Name System Security Extensions (DNSSEC) into the Internet root zone. The company claims that in doing so, it joins a select group of Registry operators leading the charge in the implementation of a suite of new security features that will help create a more secure internet.

It avers that DNSSEC is a set of specifications for securing certain kinds of information provided by the Domain Name System (DNS) that is designed to protect the Internet from specific types of attacks, such as DNS cache poisoning, which can lead to cyber-crimes such as identity theft. With full end-to-end deployment, it will eventually allow internet users to know with certainty that they have been directed to the precise website they intended to reach.

The company says that the smooth implementation of DNSSEC follows several months of careful planning and a successful test phase in January 2011. A strong partnership with Neustar, Inc., the .CO Registry's technology services partner, was a critical success factor.

"We're proud to be announcing the successful implementation of DNSSEC today," said Nicolai Bezsonoff, COO of .CO Internet. ".CO is one of the fastest growing domain extensions in the world, and registrants and end users can rest assured that we are committed to providing the highest level of internet security - both now and into the future."

"By implementing DNSSEC so soon after the launch of .CO as a global domain, the .CO Registry has reaffirmed its commitment to ensuring the security and integrity of the .CO name space," said Tim Switzer, Vice President of Domain Name Registry Services at Neustar. "We look forward to continuing to support the .CO Registry as it plays an increasingly active role in addressing the security challenges of the 21st century - and in helping to develop the policies, standards and practices that govern the global internet.""

Performance hit could be the price of DNS security

Recent security fixes to the Domain Name System have bought the Internet community time to implement a more permanent solution in the form of the DNS Security Extensions, but the job of putting the protocols into place has only begun, said one industry observer. And when DNS zones are signed securely, there will likely be a trade-off in performance.

A study by Infoblox, which makes network management automation tools, showed a fourfold increase in the number of digitally signed zones from 2009 to 2010, said Vice President of Architecture Cricket Liu. But that still amounted to only 0.022 percent of zones that had been signed with DNSSEC.

Implementing DNSSEC to ensure that IP address information received in response to DNS queries is legitimate is complicated by two factors. First, the system requires a chain of trust for validating digital signatures, which means they will not work unless the protocols are enabled on a substantial portion of the Internet. Fortunately, the root zone at the top of the DNS hierarchy has been signed, and a number of top-level domains immediately under it have also been signed.

“The last big domino to fall is going to be .com, which is scheduled to be signed in March,” Liu said Jan. 25 during a talk in Washington. “This is the year of no excuses because .com is signed this year.”

VeriSign Launches Cloud Security Service

VeriSign Inc. has just launched its newest cloud computing service designed to ease the implementation of Domain Name System Security Extensions (DNSSEC). Bizjournals states that the DNSSEC provides an additional layer of security to all users of the internet by protecting against cache websites and "man-in-the-middle" attacks. These attacks occur when forged data is used to redirect users to fraudulent websites and unintended addresses.

The VeriSign DNSSEC Signing Service will allow companies to incorporate signing and provisioning into their databases while reducing costs, according to Bizjournals. This service is designed specifically for registrars who provide DNS hosting and management services for their registrants without the additional complexity of signing and managing the keys associated with DNSSEC.

Kaminsky To Release 'Phreebird' For Easy DNSSEC

Free toolkit lets organizations, developers test-drive new DNS security protocol

Renowned researcher Dan Kaminsky tomorrow at Black Hat Abu Dhabi will release a free toolkit that lets organizations test-drive DNSSEC deployment and also demonstrates his claims that the protocol is simple to implement.

"I've been making a lot of claims and promises about what DNSSEC is capable of and why the security industry should care. This is the argument I've been putting forth, in code form. This is for real," says Kaminsky, who will make the Phreebird Suite 1.0 kit available tomorrow on the Black Hat website. Kaminsky gave a sneak peek demonstration of Phreebird at Black Hat USA in July.

Phreebird Suite 1.0 is a real-time DNSSEC proxy that sits in front of a DNS server and digitally signs its responses. "This is a collection of technologies [that show how] DNSSEC can be very easily deployed on the server side and trivially on client side," he says. The code is not for operational use, he says, but for testing out the technology.

"This code is cool. It makes DNSSEC easy to achieve," Kaminsky says. "It makes it easy to take your existing DNS deployment and supplement it with DNSSEC services."

The goal is to show how DNSSEC could be used to "bootstrap" trust -- a.k.a. authentication -- across organizations, he says, authenticating clients, business partners, customers, contractors, and other groups with one another. DNSSEC has been in the works for nearly two decades: It was finally fully deployed in the root this summer and so far has been implemented in the .gov, .net, .edu, and .org. domains. The .com domain will be signed by DNSSEC in March. The protocol is considered the key to preventing attacks exploiting the now-infamous cache-poisoning vulnerability Kaminsky revealed at Black Hat USA in 2008.
Kaminsky hopes to dispel concerns that DNSSEC will be complex, disruptive, and expensive to deploy in organizations. "Application developers don't want to be cryptography experts," Kaminsky says. "They just want the key ... and to move on."

Phreebird automatically generates keys and provides real-time signing. There is "zero configuration" on the server side with the tool. "There is enough context in the DNS reply to figure out all of the necessary settings for how to sign it. You don't have to have a huge amount of preconfiguration. This is a revolution here," Kaminsky says.

The tool requires using GoDaddy for creating a test .org domain, and in the end it takes about 30 seconds to get valid, signed records via the Internet, according to Kaminsky.

On the client side, Phreebird includes Phreeload, a tool that adds DNSSEC support to OpenSSL applications and sits at the authentication layer. DNSSEC can be used in lieu of of X.509 certificates: Phreebird's Phreeload tool basically provides authentication without certificates, using DNSSEC instead. "At present, it's surprisingly difficult and expensive to validate key material via X509 and CAs [certificate authorities]. I'm demonstrating how to make it easy and inexpensive to validate the same material using DNSSEC," Kaminsky says.

Kaminsky is also working on a Phreebird tool that lets email systems use DNSSEC for authenticating correspondents. "When my mom receives an email from the bank, she should know it's from the bank," he says.

Meanwhile, Kaminsky is urging fellow researchers to hack at Phreebird to look for vulnerabilities. He's hoping to get up-front input on any major vulnerabilities.

Observers recommend broader role for government in cybersecurity

Public service campaigns to promote safe Web surfing and developing best practices for fending off cyberattacks are not constructive activities for the government, a panel of cybersecurity experts told Federal Communications Commission officials on Friday.

FCC is now identifying the five most critical threats to the Internet, as well as a plan to address such risks in accordance with the Obama administration's National Broadband Plan, a roadmap for attaining ubiquitous, affordable high-speed Internet access. To assess the threat landscape, the agency on Friday sought the input of about 10 security officials who work for Internet service providers, research institutions and the government.

The most vocal participants said the mercurial nature of attacks makes it nearly impossible to devise defensive procedures or rely on computer users to ensure that viruses don't spread. The most effective role for the government is preparing for the unknown, they said.

October marked the government's annual cybersecurity awareness month. This year's theme was the notion that cybersecurity is a shared responsibility among the government, network services providers and Web surfers.

But James Lewis, a senior fellow at the Center for Strategic and International Studies, a Washington think tank, said educating end users will not protect the Internet.
"I've kind of given up on the end points. We had National Cybersecurity Awareness month last month. A complete waste of time," he said. "We're never going to get the end, the edge, to be safe. It's never going to happen."

Instead, the government should concentrate on which agency or combination of agencies, such as FCC and the Homeland Security Department, should coordinate with ISPs, Lewis said. They should cooperate to ensure that customers, including federal workers, are supplied almost automatically with the best defenses against malevolent intruders.

An example of the need for such proactive tactics is the shift from attacks against networks to botnets. Botnets -- organized by cybercriminals -- invisibly hijack multiple Internet users' computers or mobile devices to spread content that steals personal information through the users' communications with others.

"We've seen less attacks on the Internet, or at us, and more using us to go after financial gain," said Ed Amoroso, senior vice president and chief security officer for AT&T. "The threat that seemed so real two or three years ago around attacks at infrastructure really in two years has changed."

Studying past attacks to defend against future threats, therefore, may not be productive, he added. "It's hard to lay out a concrete set of best practices and follow it because what we do is so fluid that we have to be willing to take the playbook and throw it out and start a new one the next week or the next month, depending on what the threat is." Amoroso said that today he is obsessed with how botnets are affecting his customers but tomorrow he could be worried about vulnerabilities with different risks and fixes.

A more effective approach for protecting government and private sector computers would be practicing solutions to worst-case scenarios, the panelists said. "Have you had a day yet where you came in and you had a directive at work, where it said: 'Don't turn on your Blackberry . . . It's probably infected. If you do, all this awful stuff is going to happen,' " Amoroso said. "And you would go, 'Ok, what do I do?' "

The government has not discussed those sorts of situations, he said. "I think this idea of preparing for a battle that we can't define today is the way we need to start to operate," Amoroso said.

But other participants said there are some strategies to reduce risks that government and industry should immediately carry out.

"It's true that this problem is not going to go away. That doesn't mean we give up on trying to solve it," said Ari Schwartz, senior Internet policy adviser at the National Institute of Standards and Technology. He likened the situation to fighting fires. "We're never going to have an end to all fire accidents. But we can come up with different standards, different technologies, different policies that help us mitigate them," such as building codes and smoke alarms, Schwartz said.

Many preventive measures are expensive for ISPs to deploy across the country. That's where the government can step in to help, even without subsidies, which the industry generally opposes, panelists noted.

The federal government -- the largest U.S. consumer -- can wield its purchasing power to require that ISPs include security enhancements in all federal contracts. Such technologies include the Domain Name System Security Extensions (DNSSEC) protocol, a set of standards for identifying server addresses that ensures that when computers and mobile devices talk to each other, hackers can't misdirect their communications to fake websites.

If agencies bought only products that support DNSSEC, that would help the Web industry afford to develop the same protections for all products and services nationwide, said Andy Ellis, senior director of information security and chief security architect for Akamai, a content delivery company.

"That's not a subsidy. That's the government as a consumer, saying, 'We feel that level of security is important for us and therefore we'll pay for it,' "Ellis said. "When the government decides to do that, people will build it. And once you've built a technology, you're really happy to go sell it to everybody else."
