The Uses and Abuses of Cryptography

Another day, another data breach, and another round of calls for companies to encrypt their databases. Cryptography is a powerful tool, but in cases like this one it's not going to help. If your OS is secure, you don't need the crypto; if it's not, the crypto won't protect your data. In a case like the Anthem breach, the really sensitive databases are always in use. more

Essential Cyber Security Steps for Your Business

Layered security is a concept that's important for anyone who wants to create a strong, successful defense strategy to understand. This is a strategy that relies on the use of multiple lines of defense in an attempt to repel any potential attacks. For this reason, it's based on the principle that says "no single form of protection is enough to stop a determined cybercriminal. more

Encryption, Our Last Line of Defense

Encryption is fundamental to our daily life. Practically everything we do online makes use of encryption is some form. Access to our financial transactions, health records, government services, and exchanged private messages are all protected by strong encryption. Encryption is the process of changing the information in such a way as to make it unreadable by anyone except for those possessing special knowledge (usually referred to as a "key"), which allows them to change the information back to its original, readable form. more

How IT and Internet Saved Lives in Haiti

Stéphane Bruno writes: "In the first few hours that followed the earthquake, mobile service was completely disrupted. It was almost impossible to place a call, due to the combination of the damages on the cellular networks and the spike in phone calls. However, on some networks, SMS service was still available. People stuck under rubbles started texting to their friends and family (in Haiti and abroad) to tell them they were still alive and needed help. Those friends and family, not knowing what to do, started posting these SOS messages on their social networks, mainly on Facebook." more

Russia to Disconnect Entirely From the Internet as Part of Cyber-Defense Measure

According to various news outlets, Russia is reported to be planning a complete Internet shut down, as part of a test of its cyber-defenses. more

Patient Care Suffers When Data Security is a Budgetary Concern

According to a recent Homeland Security News Wire article, nearly 8 million patient medical records were compromised over the course of the previous two years due to data security breaches. As more hospitals and patient care providers move to store patient data electronically -- primarily as a cost savings effort -- the risk and exposure of our private medical information increases while our individual control over this information diminishes. more

Network Security: How Attackers Gain Access from Inside

Most people - mistakenly - believe that they are perfectly safe behind a firewall, network address translation (NAT) device or proxy. The fact is quite the opposite: if you can get out of your network, someone else can get in. Attackers often seek to compromise the weakest link in a network and then use that access to attack the network from the inside, commonly known as a "pivot-and-attack." more

Microsoft is Abandoning SHA-1 Hashes for Updates - But Why?

Microsoft is shipping a patch to eliminate SHA-1 hashes from its update process. There's nothing wrong with eliminating SHA-1 - but their reasoning may be very interesting. SHA-1 is a "cryptographic hash function". That is, it takes an input file of any size and outputs 20 bytes. An essential property of cryptographic hash functions is that in practice (though obviously not in theory), no two files should have the same hash value unless the files are identical. more

Website Seals of Approval: Can You Trust Them?

The abuse of well-known seal of approvals seems to be the latest ruse used by online fraudsters. Leveraging reputable names that existed long before anyone heard of the Internet is a blaring reminder that even trustworthy seals are not off limits to scammers. In fact, linking to reliable sources of reviews and certification is proving to be an essential part of any fraud strategy today. more

A Great Collaborative Effort: Increasing the Strength of the Zone Signing Key for the Root Zone

A few weeks ago, on Oct. 1, 2016, Verisign successfully doubled the size of the cryptographic key that generates DNSSEC signatures for the internet's root zone. With this change, root zone DNS responses can be fully validated using 2048-bit RSA keys. This project involved work by numerous people within Verisign, as well as collaborations with ICANN, Internet Assigned Numbers Authority (IANA) and National Telecommunications and Information Administration (NTIA). more

Reducing the Risks of BYOD with DNS-Based Security Intelligence; Part 1: Understanding the Risks

Ah, BYOD. How I love thee. BYOD, or "Bring Your Own Device", gives me choices. I can use a device at work I actually like and am most effective with. (How did I ever get by without my iPad?) But BYOD comes with challenges. Personal devices can be infected with malware. Once they're connected to an enterprise's network, they can be controlled by a bot master to hijack enterprise resources and wreak havoc as part of a botnet. more

Reaction: Do We Really Need a New Internet?

The other day several of us were gathered in a conference room on the 17th floor of the LinkedIn building in San Francisco, looking out of the windows as we discussed some various technical matters. All around us, there were new buildings under construction, with that tall towering crane anchored to the building in several places. We wondered how that crane was built, and considered how precise the building process seemed to be to the complete mess building a network seems to be. more

Experts Propose Plan for More Secure Wi-Fi Devices

Over 260 global network and security experts have collectively responded to the newly proposed FCC rules laid out in ET Docket No. 15-170 for RF Devices such as Wi-Fi routers by proposing a new approach to improve the security of these devices. The letter warns FCC ruling will cause more harm than good and risk a significant overreach of the Commission's authority. more

Why More Registries Should Be Talking About DNS Security

I've been incredibly lucky in my time at Neustar to lead both the exceptional Registry and Security teams. While these divisions handle their own unique product and service offerings, it's clear that they have some obvious crossovers in their risks, opportunities and challenges. Having been closely involved in the strategy of both these teams, it strikes me that there is more we as Registry Operators and service providers can and should be doing to align the world of cybersecurity with that of domain names. more

The Effects of the Forthcoming FCC Privacy Rules on Internet Security

Last week, the Federal Communications Commission (FCC) announced new privacy rules that govern how Internet service providers can share information about consumers with third parties. One focus of this rulemaking has been on the use and sharing of so-called "Consumer Proprietary Network Information (CPNI)" - information about subscribers - for advertising. The Center for Information Technology Policy and the Center for Democracy and Technology jointly hosted a panel exploring this topic last May... more
