IDG Contributor Network: Overcoming kludges to secure web applications

When it comes to technology, nothing is static, everything is evolving. Either we keep inventing mechanisms that dig out new security holes, or we are forced to implement existing kludges to cover up the inadequacies in security on which our web applications depend.The assault on the changing digital landscape with all its new requirements has created a black hole that needs attention. The shift in technology, while creating opportunities, has a bias to create security threats. Unfortunately, with the passage of time, these trends will continue to escalate, putting web application security at center stage.Business relies on web applications. Loss of service to business-focused web applications not only affects the brand but also results in financial loss. The web application acts as the front door to valuable assets. If you don’t efficiently lock the door or at least know when it has been opened, valuable revenue-generating web applications are left compromised.To read this article in full, please click here

DNS in the cloud: Why and why not

As enterprises consider outsourcing their IT infrastructure, they should consider moving their public authoritative DNS services to a cloud provider’s managed DNS service, but first they should understand the advantages and disadvantages.To read this article in full, please click here(Insider Story)

Response: Vendors Pushing Stretched Layer-2

Got this response to my Stretched Layer-2 Revisited blog post. It’s too good not to turn it into a blog post ;)

Recently I feel like it's really vendors pushing layer 2 solutions, rather than us (enterprise customer) demanding it.

I had that feeling for years. Yes, there are environment with legacy challenges (running COBOL applications on OS/370 with emulated TN3270 terminals comes to mind), but in most cases it’s the vendors trying to peddle unique high-priced non-interoperable warez.

What Drives IPv6 Deployment?

It's been six years since World IPv6 Launch day on the 6th June 2012. In those six years we've managed to place ever increasing pressure on the dwindling pools of available IPv4 addresses, but we have still been unable to complete the transition to an all-IPv6 Internet.

Weekend Reads 051818: Botnets and Throwhammer

The Facebook freak-out provides an outlet for fears regarding the digital environment we inhabit. A few companies control most channels of information. The gadgets that we use for convenience and entertainment also create the mechanisms for near-total surveillance, from tracking devices in our pockets to wiretaps in our homes—hi, Alexa! Someone besides Santa is watching and knows whether you have been naughty or nice. —Nathanael Blake @Public Discourse

Within just 10 days of the disclosure of two critical vulnerabilities in GPON router at least 5 botnet families have been found exploiting the flaws to build an army of million devices. Security researchers from Chinese-based cybersecurity firm Qihoo 360 Netlab have spotted 5 botnet families, including Mettle, Muhstik, Mirai, Hajime, and Satori, making use of the GPON exploit in the wild. —Swati Khandelwal @The Hacker News

Exploitation of Rowhammer attack just got easier. Dubbed ‘Throwhammer,’ the newly discovered technique could allow attackers to launch Rowhammer attack on the targeted systems just by sending specially crafted packets to the vulnerable network cards over the local area network. Known since 2012, Rowhammer is a severe issue with recent generation dynamic random access memory (DRAM) chips in which repeatedly accessing a row of memory Continue reading
