Software-Defined Perimeter Essentials

I’ve written about Software-Defined Perimeter (SDP) a few times, as I think this model is a strong fit for today’s IT cocktail made up of mobile applications, public cloud infrastructure and pervasive security threats. What is an SDP? The model is really based upon the “black cloud” concept coming out of the Defense Information Systems Agency (DISA) where network access and connections are allowed on a “need-to-know” basis. Similarly, the Cloud Security Alliance (CSA) refers to SDPs as “on-demand, dynamically-provisioned, air gapped networks.”Several vendors, including Cryptzone and Vidder, actively market SDP offerings. In addition, Google’s BeyondCorp is a homegrown SDP project that Google has made public and highly visible. While these efforts clearly fall under the SDP category, I viewed the SDP model a bit more broadly. SDP is clearly associated with numerous innovations and initiatives of the past, including next-generation firewalls, network access control (NAC) and even 802.1X, so there are plenty of SDP-like solutions from vendors such as Cisco, HP (Aruba) and Pulse Secure (formerly part of Juniper). To read this article in full or to leave a comment, please click here

Cost of a Windows zero-day exploit? This one goes for $90,000

Ever wonder how much an exploit for a previously unknown vulnerability that affects all Windows versions costs on the black market? The answer, according to a recent offer seen on a cybercrime forum, is $90,000.The offer was observed by researchers from security firm Trustwave on an underground market for Russian-speaking cybercriminals, where users hire malware coders, lease exploit kits, buy access to compromised websites or rent botnets.Zero-day exploits -- exploits for unpatched vulnerabilities -- are typically used for cyberespionage. Hackers sell them to governments and large corporations, under strict non-disclosure agreements, often through specialized brokers, so it's uncommon to see them traded on cybercrime forums.To read this article in full or to leave a comment, please click here

$90,000 zero-day exploit for sale: It could potentially impact all Windows OS versions

On the Russian underground forum exploit.in, seller “BuggiCorp” has a zero-day for sale that purportedly works against all versions of Windows. The price tag is $90,000.In the words of the email alerting me to this zero-day, this vulnerability “could affect almost all Windows machines on the planet.” If the local privilege escalation (LPE) vulnerability truly does exit in all versions of Microsoft Windows, from Windows 2000 up to Windows 10, then it could potentially impact “over 1.5 billion Windows users.”According to SpiderLabs security researchers at Trustwave, who found the post on a cybercriminal underground forum, “It seems the seller has put in the effort to present himself/herself as a trustworthy seller with a valid offering. One of the main indicators for this is the fact that the seller insists on conducting the deal using the forum's admin as the escrow.”To read this article in full or to leave a comment, please click here

Review: Microsoft masters microservices

Many businesses either have implemented or claim to be implementing microservice architectures, for better or for worse. Microservice architectures give you strong module boundaries, independent deployment and independent scaling of lightweight pieces, isolation of concerns, and the opportunity to use whatever technology is appropriate for each small service. On the other hand, distributed systems inherently have higher latency and more opportunities for failure than monolithic systems, as well as higher operational complexity, so the application has to be “big enough” to justify the overhead of being distributed.To read this article in full or to leave a comment, please click here(Insider Story)
