DLSP – QoS-Aware Routing Protocol on Software Gone Wild

When I asked “Are there any truly QoS-aware routing protocols out there?” in one of my SD-WAN posts, Marcelo Spohn from ADARA Networks quickly pointed out that they have one – Dynamic Link-State Routing Protocol.

He also claimed that DLSP has no scalability concerns – more than enough reasons to schedule an online chat, resulting in Episode 40 of Software Gone Wild. We didn’t go too deep this time, but you should get a nice overview of what DLSP is and how it works.

How to use stipends to ensure BYOD success

Stipends are a way for businesses to reimburse employees for a portion of their wireless costs and, if implemented properly, address these common issues: cost, eligibility, control and taxes. Here’s how:

* Costs. When businesses talk about costs, they generally are referring to either time or money. And companies opting to use expense reports for stipends will find the task occupies a good bit of both. It’s time-consuming for accounting departments to sort through individual expense reports and issue payments only after an employee’s usage has been verified. It’s no surprise, then, that an Aberdeen Group study suggests each expense report costs $18 to process. Compounding those costs, companies opting for this method will issue hundreds or even thousands of payments each month, so the benefits that attend stipends can be quickly outweighed.

Under DDoS attack? Look for something worse

When businesses are hit by noticeable distributed denial-of-service attacks, three-quarters of the time those attacks are accompanied by another security incident, according to Kaspersky Lab.Those other attacks may or may not originate from the same party, but they can go undetected if IT staff is totally focused on defending against the DDoS, says Evgeny Vigovsky, head of Kaspersky DDoS Protection.“In many cases, it may be a coordinated effort, but even if these attacks originate from different sources, IT staff have to allocate resources to solve two problems at the same time, under a lot of stress,” Vigovsky says. Kaspersky polled top managers and IT pros at 5,500 companies in 26 countries about their experiences with DDoS attacks.To read this article in full or to leave a comment, please click here

Malware enables cheating at online poker

Online poker malware lets players cheat by getting a peek at cards held by opponents whose machines have been infected.The Trojan, called Win32/Spy.Odlanor, is typically downloaded by victims because it is disguised as installers or resources such as poker databases and poker calculators, according to the ESET WeLiveSecurity blog.“In other cases, it was loaded onto the victim’s system through various poker-related programs … such as Tournament Shark, Poker Calculator Pro, Smart Buddy, Poker Office, and others,” the blog says.Once installed it grabs screenshots of the PokerStars and Full Tilt Poker clients, letting the attackers see what cards the victim holds. In order to carry out the scam, the cheaters have to find and join the table at which the infected machine is playing.To read this article in full or to leave a comment, please click here

IDG Contributor Network: What does a next-generation WAN look like?

After years of sitting in the shadow of virtualization, SaaS, containers, and all the other exciting IT trends, the wide area network is finally getting some attention. These other trends are actually drivers for this change in many cases; while WAN architectures have remained relatively static in recent years, the applications they need to support have changed beyond recognition. This is driving the need to re-think what the WAN looks like and how it operates.The phrase 'next-generation WAN' will mean different things to different enterprises, but let's identify some of the characteristics that are starting to become more common. Some of these are new, but in many cases the next-generation WAN is a new network methodology or mindset. This can impact the technologies used, insourcing/outsourcing decisions, and functionality provided by the network.To read this article in full or to leave a comment, please click here

Breach Presumption: The East-West Data Center Security Problem

A recurring trend in security briefings I've taken over the last year is that breaches are assumed. If you don't assume your infrastructure has been breached, you're ignorant, and probably willfully so. Ostrich, meet sand. A weird response my brain had to this is to ponder that if we've lost the war, why are we still fighting?

Fiber bandits: FBI hunting serial fiber-cutting vandals in California

AT&T recently announced a $250,000 reward to anyone with information on whoever entered its underground facilities in Livermore, California – a San Francisco suburb – and severed two of its fiber cables earlier this week, USA Today reported yesterday. The vandalism echoes 14 similar attacks that have destroyed damaged fiber cables and disrupted internet service for customers of several service providers in the northern California region dating back to July 2014. USA Today also reported a similar attack in late June, when "someone broke into an underground vault and cut three fiber-optic cables belonging to Colorado-based service providers Level 3 and Zayo," according to an earlier USA Today report. The FBI confirmed at the time that it was investigating connections between that attack and 11 similar outages in the region over the year prior. To read this article in full or to leave a comment, please click here
